    [0001] The present disclosure relates to vehicle seat supports, seat assemblies including such supports, and methods of mounting such supports in a vehicle.
    [0002] Technological background
    [0003] More particularly, the present description relates to vehicle seat supports comprising two parallel rails on which the vehicle seat can slide and a footrest.
    [0004] Abstract
    [0005] The aim of the present description is in particular to improve the comfort provided to the user by such vehicle seat supports.
    [0006] To this end, the present description proposes a vehicle seat support comprising: - a first rail extending between a rear end and a front end in a longitudinal direction, a second rail parallel to said first rail and extending between a rear end and a front end, the first rail and the second rail being intended to be fixed to a vehicle floor, - a central module which is slidably mounted on the first rail and the second rail and which is adapted to support the vehicle seat, a footrest slidably mounted on the first rail and the second rail between the respective front ends of the first and second rails and the central module, the footrest being adapted to receive the feet of an occupant seated on the seat, - a first actuation system able to slide the central module along the first rail and the second rail, - And a second actuation system able to slide the footrest along the first rail and the second rail independently of said central module.
    [0007] By virtue of these arrangements, the occupant of the seat can independently actuate the position of the seat and the position of the footrest, which enables him to easily choose the position of the assembly which is the most comfortable. for him. Optionally, the control of the two actuation systems can be coordinated by an electronic control device such as a central unit controlling the two actuation systems, but in all cases, the two actuation systems are mechanically independent. one another. In particular, the electronic control device allows any one or more of the following configurations for the vehicle seat support: - A “morphological adaptation” mode, in which the advance (respectively the retreat) of the footrest along the rails is carried out with a retreat (respectively an advance) of the seat, for example simultaneously. This configuration is particularly suited to accommodate a variety of size of an occupant. - A "conservation" mode, in which the advance (respectively the retreat) of the footrest along the rails is carried out with an advance (respectively a retreat) of the seat, for example simultaneously. For example, this configuration makes it possible to maintain the same distance between the footrest and the seat when the passenger shifts longitudinally. - A "comfort" mode in which the advance (respectively the retreat) of the footrest along the rails is carried out with a retreat of the seat and an inclination towards the rear of the seat back (respectively an advance of the seat and a forward tilt of the seat back), for example simultaneously. This configuration is particularly suitable for changing from a nominal configuration to a comfort position and vice versa. Thus the use of an electronic control device to coordinate the two actuation systems, which are independent of each other, allows the implementation of several modes of movement of the seat and the footrest for a increased flexibility and ease of use for the user. Each of these modes is obtained by actuation of an actuator (for example a button) which controls the electronic control device.
    [0008] According to one embodiment, the central module comprises a first plate which is adapted to partially cover the floor of the vehicle, and the footrest comprises a second plate which is adapted to partially cover the vehicle floor, the first plate and the second. plate being arranged to overlap such that the vehicle floor is covered by the first plate and the second plate between the center module and the footrest regardless of the relative position of the center module and the footrest.
    [0009] Thus, the reliability of the assembly is improved because the passenger's feet can also rest on the second plate and do not risk interfering with the sliding of the footrest or with the rails.
    [0010] According to one embodiment, the first rail and the second rail each comprise at least one flap respectively covering the rail between the central module and the footrest.
    [0011] Thus, the reliability of the assembly is improved because the rails are protected against the entry of foreign bodies into the rails which could interfere with the sliding of the footrest and / or the central module.
    [0012] Optionally, said at least one flap can be arranged obliquely with respect to the horizontal, on an open face of the corresponding rail.
    [0013] According to one embodiment, the at least one flap is dimensioned and arranged to entirely cover the rail between the central module and the footrest.
    [0014] According to one embodiment, the at least one flap is secured to a first element chosen from among the central module and the footrest and is arranged to engage under a lateral part secured to a second element chosen from among the central module. and the footrest.
    [0015] According to one embodiment, the first rail and the second rail each comprise a first flap and a second flap together covering the rail between the central module and the footrest, the first flap and the second flap being respectively connected to the central module and at the footrest.
    [0016] For example, the first flap and the second flap are mounted to overlap when the center module and footrest move closer to each other.
    [0017] For example, the first flap is slidably mounted in the longitudinal direction relative to the central module and is resiliently biased towards the second flap and / or the second flap is slidably mounted in the longitudinal direction relative to the footrest and is resiliently biased towards the first flap, the first flap and the second flap being adapted to abut axially against each other by sliding the first flap and / or the second flap when the central module and the footrest move closer to one another the other.
    [0018] According to one embodiment, the first actuation system comprises at least one motor.
    [0019] For example, the first actuation system comprises a first motor which is able to drive the central module on the first rail and a second motor which is able to drive the central module on the second rail (advantageously, the two motors are controlled so synchronized).
    [0020] Thus, the sliding of the central module on the rails is more reliable.
    [0021] According to one embodiment, the second actuation system comprises at least one motor.
    [0022] According to one embodiment, the footrest is mounted on a support which comprises a first shuttle which is able to slide on the first rail and a second shuttle which is able to slide on the second rail, the first shuttle and the second shuttle. being interconnected by at least one rigid structure, the motor being carried by the rigid structure.
    [0023] Optionally, the support structure may include at least one cross member secured to the two shuttles and said motor is fixed to said cross member.
    [0024] According to one embodiment, the central module comprises a rigid structure which is secured to two slides mounted to slide respectively along the two rails.
    [0025] According to one embodiment, the first rail and the second rail are secured together by at least one transverse structure and kept parallel by the central module and the footrest.
    [0026] The present description also relates to a seat assembly comprising a vehicle seat support according to the present description and a vehicle seat which is mounted on the central module.
    [0027] Finally, the present description also relates to a method of mounting an assembly as defined above, comprising at least the following steps: - preliminary assembly of a first assembly comprising the first rail, the second rail, a transverse structure secured to the first rail and to the second rail, and at least one rigid support structure belonging to the central module or to the footrest, said structure of support being integral with two elements mounted to slide respectively on the first rail and on the second rail, - fixing of the first assembly on the vehicle floor.
    [0028] According to one embodiment, during the preliminary assembly step, the central module is mounted on the rails by a first rigid support structure integral with two slides mounted to slide respectively on the first rail and on the second rail, and the footrest is mounted on the rails by a second rigid support structure integral with two shuttles mounted to slide respectively on the first rail and on the second rail.
    [0029] Optionally during the preliminary assembly step, the seat can be mounted on the central module.
    [0030] Optionally, during the preliminary assembly step, at least one cable is placed in at least one of the rails, said at least one cable being connected to the first actuating device and to the second actuating device, and said to less cable is connected to the vehicle when attaching the first set to the vehicle floor.
    [0031] Furthermore, the vehicle seat support according to the present description could have a single rail instead of two rails. In this case, the vehicle seat support comprises: a rail extending between a rear end and a front end in a longitudinal direction, said rail being intended to be fixed to a floor of the vehicle, - a central module which is slidably mounted on the rail and which is adapted to support the vehicle seat, - a footrest slidably mounted on the rail between the front end of the rail and the central module, the footrest being adapted to receive the feet of an occupant seated on the seat, - a first actuation system able to slide the central module along the rail and the rail, - And a second actuation system able to slide the footrest along the rail independently of said central module.
    [0032] Finally, the vehicle seat support according to the present description could comprise one or two rails for guiding the central module and one or two other rails for guiding the footrest in the longitudinal direction. In this case, the vehicle seat support comprises: - at least one seat guide rail extending between a rear end and a front end in a longitudinal direction, - at least one footrest guide rail extending between a rear end and a front end in the longitudinal direction, the seat guide rail and the footrest guide rail being intended to be fixed to a floor of the vehicle, - a central module which is slidably mounted on said seat guide rail and which is adapted to support the vehicle seat, - a footrest slidably mounted on said footrest support rail, the footrest being adapted to receive the feet of an occupant seated on the seat, - a first actuation system able to slide the central module along the seat guide rail, - And a second actuation system able to slide the footrest along the footrest guide rail independently of said central module.

    [0056] More detailed description
    [0057] Figure 1 shows in perspective a vehicle seat support which is adapted to support a seat 90 (shown in Figure 18) of a vehicle and includes a footrest 40. The footrest 40 enables the occupant of the seat to put his feet down while sitting on the seat.
    [0058] The vehicle seat support comprises a pair of parallel rigid rails, for example of metal, extending in a longitudinal direction X, namely a first rail 10 extending between a rear end 11 and a front end 12, and a second rail 20 extending between a rear end 21 and a front end 22. These rails are intended to be fixed to the floor (not shown) of the vehicle. The direction "front - rear" and the adjectives "front" and "rear" are defined with respect to the direction of the longitudinal axis X. The rails 10, 20 are arranged facing each other in one direction. transverse Y which is perpendicular to the longitudinal direction X, the XY plane being horizontal. The terms “above” / “over” and “below” / “under” are defined with respect to a vertical Z axis perpendicular to the XY plane, the X, Y, and Z axes forming an orthogonal frame of reference. The term "interior" designates the part of an element which is directed towards the middle (the interior) of the assembly, that is to say towards the longitudinal axis X which divides the assembly into two symmetrical parts. .
    [0059] As clearly visible in particular in Figures 1, 3-4, 6, 10-11, 13, the first rail 10 and the second rail 20 can be metal profiles each having for example a C-shaped section (in a perpendicular plane to the longitudinal axis X). For example, as shown in the figures, the open face of the first rail 10, which extends longitudinally between its two ends 11, 12, is directed towards the interior of the assembly, making an angle with respect to the transverse axis Y. Similarly, the open face of the second rail 20, which extends longitudinally between its two ends 21, 22, is directed towards the interior of the assembly, making an angle with respect to the transverse axis Y. Thus, in the example shown, each of these two open faces is directed obliquely upwards (positive direction of the Z axis), forming a V between them.
    [0060] More particularly, the first rail 10 has a first opening 13 which extends longitudinally between its two ends 11, 12 and which is directed towards the interior of the assembly. Likewise, the second rail 20 has a second opening 23 which extends longitudinally between its two ends 21, 22 and which is directed towards the interior of the assembly. The first opening 13 and the second opening 23 are located opposite each other along the entire length of the rails 10, 20.
    [0061] The assembly also includes a central module 30 which is slidably mounted on the rails 10, 20 and on which a seat 90 is intended to be fixed. The seat 90 is therefore integral with the central module 30, as illustrated in FIG. 18.
    [0062] The central module 30 may include a first rigid plate 35, for example metallic, which covers the entire module 30. The first central plate generally extends along the XY plane. The first plate 35 can extend transversely between the two rails 10, 20 so as to cover the vehicle floor between the two rails 10, 20.
    [0063] The seat 90 is fixed on the central module 30 by mechanical fasteners 95 (visible in FIG. 1). For example, these fasteners 95 are arranged at the four vertices of a rectangle, that is to say each near one of the corners of the first plate 35 which covers the central module 30. The fasteners 95 can for example be screws / nuts. Alternatively, the fixings 95 are threaded holes allowing the seat to be fixed by screwing.
    [0064] The central module 30 is mounted on slides 513, 523 which are mounted to slide respectively on the rails 10, 20 (see Figures 3 and 4, as well as Figures 16 and 17). The first slide 513 comprises, for example, rollers 513a which rest on the lower part of the first rail 10 in order to allow this sliding. These rollers are shown in Figure 8. The other slide 523 includes similar rollers. The term slide is not limited to a particular shape or to a particular mounting on the rails 10, 20: it designates any element slidably mounted along one of the rails 10, 20, in the X direction.
    [0065] The sliding of the central module 30 along the rails 10, 20 is achieved by a first actuation system 50. For example, the first actuation system 50 comprises at least one electric motor, which allows automatic displacement of the central module 30. In the example shown, the first actuation system 50 can comprise a first motor 51 which is able to drive the slide 513 on the first rail 10 (in particular, the first motor 51 can control (via a rod 515) a pinion (not shown) engaged with a rack 14 belonging to the first rail 10) and a second motor 52 which is able to drive the slide 523 on the second rail 20 (in particular, the second motor 52 can control (by via a rod 525) a pinion (not shown) engaged with a rack 14 belonging to the second rail 20). The first motor 51 and the second motor 52 are visible in Figures 1 and 2 (see below). The rails 10, 20, motors 51, 52 and the slides 513, 523 may for example be as described in patent application FR1900015 filed on January 2, 2019. The motors 51, 52 are advantageously controlled in a synchronized manner.
    [0066] Alternatively, the actuation system 50 could be manual.
    [0067] The first plate 35 helps protect the mechanical elements of the central module 30 (in particular the actuation system 50).
    [0068] Figures 2 and 3 show the support structure of the central module 30. The central module 30 comprises a rear transverse cross member 33 rigid (for example metallic) and a transverse front cross member 34 rigid (for example metallic) which each extend from the first. rail 10 to the second rail 20. The cross members 33, 34 are each fixed to the slider 513 of the first rail 10 and to the slider 523 of the second rail 20. The fasteners 95 which hold the seat 90 on the central module 30 fix the seat 90 and the first plate 35 on the rear cross member 33 and the front cross member 34. In FIG. 3 the motor 51 is not shown for the sake of clarity. It will be noted that the central module 30 could comprise any other rigid support structure interconnecting the slides 513, 523. Such a structure could for example comprise a single cross member instead of two, or take any other form.
    [0069] Figure 4 details an example of fixing the rear cross member 33 and the front cross member 34 on the slide 513 which slides in the first rail 10. In Figure 4 the motor 51 does not appear for the sake of clarity. One end of the rear cross member 33 is fixed by a mechanical link (for example screw / nut as illustrated) on a rear leg 331 integral with the slide 513. The rear leg 331 extends for example transversely towards the inside of the seat support. vehicle from its distal end where it is fixed to the slider 513. Likewise, one end of the front cross member 34 is fixed by a mechanical connection (for example screw / nut as illustrated) on a front leg 332. The front leg 332 extends for example transversely towards the interior of the vehicle seat support from its distal end where it is fixed on the slider 513.
    [0070] The rear transverse bar 33 and the front transverse bar 34 are similarly mounted on the slider 523 which slides in the second rail 20. The above description of the slider 513, the rear leg 331 and the front leg 341 is therefore valid for the fixing of the bars 33, 34 on the other slide 523, by replacing the references 10, 331 and 341 by the references 20, 332 and 342 respectively in the description above. These latter references are shown in parentheses in Figure 4.
    [0071] Figures 5 and 6 show the structure of the first plate 35. At its lateral edge which covers the first rail 10, the first plate 35 can be extended forward along this first rail 10 by a longitudinal protuberance 351. This protuberance 351 covers part of the first rail 10, at least upward and inwardly of the vehicle seat support, and contributes, with a primary flap 361 (see below) to cover the first rail 10 for avoid or limit in particular the risks of foreign bodies entering the first rail 10 and the risks of injury to users with the first rail 10. The longitudinal protuberance 351 covers at least the rear end of the primary flap 361.
    [0072] Similarly, the first plate 35 extends forward along the second rail 20 by another longitudinal protuberance 352, at its other lateral edge which covers the second rail 20. This other protuberance 352 covers part of the second. rail 20, at least upwards and towards the interior of the vehicle seat support, and contributes, with a primary flap 362 (see below) to hide the second rail 20 between the module 30 and the footrest 40 The longitudinal protuberance 321 covers at least the rear end of the primary flap 362. The longitudinal protuberances 351, 352 have an inner face which is directed towards the interior of the assembly and which covers the opening 13, 23 of the rail. 10, 20, and an upper face which covers the upper part of the rail 10, 20. This inner face may be oblique in particular if the opening 13, 23 of the rail 10, 20 opens obliquely upwards (with an angle by relative to the transverse axis Y, as shown in the figures). Alternatively, this inner face can be vertical, in particular if the opening 13, 23 of the rail 10, 20 opens out horizontally in the XY plane. The protuberances 351, 352 are also visible in Figure 12.
    [0073] The assembly also includes a footrest 40 which comprises a body 41 which is slidably mounted on the rails and a longitudinal extension 42 which is intended to receive the feet of an occupant seated on the seat. The footrest 40 is located in front of the central module 30. The body 41 therefore slides between the front ends (12, 22) of the rails (10, 20) and the central module 30. The body 41 extends from the first rail 10 to the second rail 20. The longitudinal extension 42 is integral with the body 41 such that the extension 42 slides integrally along the rails 10, 20 with the body 41. The longitudinal extension 42 extends the body 41. of the footrest 40 in the longitudinal direction X towards the front, that is to say in the direction opposite to the central module 30. The body 41 and the extension 42 cover a portion of the floor located between the rails (10, 20) . As illustrated in Figure 1, the upper face 425 (which may in particular be flat) of the extension 42, on which the passenger's feet are intended to rest, makes a fixed angle with the horizontal plane XY. Alternatively, the extension 42 could be pivotally mounted on the body 41 by a pivot link (along the transverse axis Y) so that this upper face 425 is able to take various orientations with the horizontal plane XY. A mechanism, manual or motorized, allows in this case to adjust the inclination of the extension 42.
    [0074] The construction of the footrest 40 is detailed below, with reference to Figures 1 and 6 to 10.
    [0075] The body 41 and the extension 42 are mounted on a support 43, clearly visible in Figure 10. The support structure 43 consists of rigid parts, for example metal. The support 43 comprises a first shuttle 431 which is able to slide in the X direction in the first rail 10 and a second shuttle 432 which is able to slide in the X direction in the second rail 20. Thus, the first shuttle 431 is accommodates in the internal space of the first rail 10, and the second shuttle 432 is housed in the internal space of the second rail 20. The first shuttle 431 comprises rollers 431a which rest on the lower part of the first rail 10 in order to allow this sliding. These rollers are visible in Figure 8 and Figure 14. The second shuttle 432 includes similar rollers. The first shuttle 431 and the second shuttle 432 are interconnected by a rigid support structure which comprises for example a rear cross member 441 and a front cross member 442. These cross members 441, 442 are also secured to the frames 443, for example at number of two, which each extend in the longitudinal vertical plane XZ and which are perpendicular to the sleepers 441, 442. Of course, the shape of the support structure is not limited to this particular example, and the term shuttle is not limited to a particular shape or to a particular mounting on the rails 10, 20: it designates any element slidably mounted along one of the rails 10, 20, in the X direction.
    [0076] The connection of the sleepers 441, 442 with the shuttles 431, 432 is now described in more detail with reference to FIG. 11. FIG. 11 illustrates the connection between the first shuttle 431 and the first rail 10. For the sake of clarity, the sleepers 441, 442 are not shown. The first shuttle 431 comprises a rear tab 4314 on which is mechanically fixed (for example by screw / nut) one end of the rear cross member 441. The first shuttle 431 also comprises a front tab 4315 on which is fixed mechanically (for example by screw / nut) one end of the front crossmember 442. These tabs (4314, 4315) extend inwardly of the vehicle seat support. The above description of the shuttle 431, of the tab 4314 and of the tab 4315 is valid for the other shuttle 432 by replacing the references 10, 431, 4314, 4315 and 6315 by the references 20, 432, 4324, 4325 and 6325 respectively in the description above. These latter references are shown in parentheses in Figure 11.
    [0077] The sliding of the footrest 40 along the rails is achieved by a second actuation system 60 visible in Figures 1, 2, 7, 10.
    [0078] The second actuation system 60 allows automatic displacement of the footrest 40. The second actuation system 60 comprises at least one electric motor 61, which is carried for example by the front cross member 442. The second actuation system 60 further comprises a drive mechanism which is connected to the motor 61. The drive mechanism may for example comprise a transmission 62 driven by the motor 61 (for example mounted in the same casing as the motor 61), a first shaft d 'drive 631 and a second drive shaft 632. The first drive shaft 631 extends from the transmission 62 to the first rail 10 in the transverse direction Y, and the second drive shaft 632 extends from the transmission 62 to the second rail 20 in the transverse direction Y. The end of the first drive shaft 631 at the level of the first rail 10 comprises a first pinion 6315 meshing with the aforementioned rack 14, and the end of the second ar The drive train 632 at the second rail 20 has a second pinion 6325 meshing with the aforementioned rack 14. The transmission 62 converts (eg by gearing) the rotation of the motor 61 at each of the drive shafts 631, 632.
    [0079] The actuation system 60 is actuated independently of the actuation system 50. The sliding of the footrest 40 thus takes place independently of the sliding of the central module 30, so that a relative positioning of the central module 30 and of the rest. -40 feet can be carried by the passenger from the seat. Thus, passenger comfort is optimal.
    [0080] As shown in Figures 1, 6, 7 and 8, the body 41 of the footrest 40 comprises a rigid base 411 (eg made of plastic) which is fixed at its front end to the rear cross member 441 of the structure. support 43. The base 411 can be flat. The extension 42 comprises a rigid base 421 (made for example of plastic material) which is fixed to the frames 443. The base 421 comprises a horizontal portion 421a which extends the base 411 and an inclined portion 421b which extends towards the forward and upward from the horizontal portion.
    [0081] The base 411 can simply rest on the rear cross member 441 and be hooked onto said rear cross member 441, for example by hooking members 411a engaged on said rear cross member 441, as can be seen in FIGS. 8 and 10. The base 411 can in in addition to resting on the floor P of the vehicle. The underside of the base 411 may further include ribs 411b parallel to the longitudinal direction X which facilitate the sliding of the base 411 on the vehicle floor (in particular on a textile covering of carpet type or the like of the floor P), in limiting friction (due to the fact that the ribs limit the contact surface between the base 411 and the floor P of the vehicle). The free spaces between the ribs 411b can possibly be used for the passage of cables, in particular cables used for the power supply of the footrest 40 or of low current cables belonging to the connectors of the footrest 40. These ribs 411b are visible on Figure 8, which is a perspective and bottom view of the footrest 40. Figure 9 is a sectional view of Figure 8 in a vertical transverse plane (YZ) which shows the relative position of the base 411 by compared to the floor P.
    [0082] The hooking members 411a can be retained on the rear cross member 441 in particular by resting the base 421 on said hooking members 411a.
    [0083] The extension 42 may include, in addition to the base 421, a plate 422 which covers the base 421, and elements 423 which are located under the front end of the extension 42 and which reinforce and protect it. This front end of the extension 42 is, for example, curved upwards to be vertical. The footrest 40 comprises, in addition to the body 41 and the extension 42, a rigid shell 45 (eg made of plastic). The shell 45 rests on the body 41 and the extension 42 which it covers. Thus, the shell 45 comprises a rear part 45a forming a second horizontal plate, and a front part 45b which is oblique and which extends parallel to the oblique part of the base 421 which it covers. The front part of this shell 45 extends transversely along the transverse axis Y from the first rail 10 to the second rail 20. The shell 45 is optionally covered with a protective or comfort layer 455, as illustrated in Figure 7.
    [0084] At its lateral edge which covers the first rail 10, the shell 45 is extended towards the rear along this first rail 10 by a longitudinal protuberance 451. As illustrated in Figures 1, 7, and 12, this protuberance 451 covers part of the first rail 10, at least upwards and towards the interior of the vehicle seat support and contributes, with a secondary flap 461 (see below) to protect the first rail 10. The longitudinal protuberance 451 covers at least the front end of the secondary flap 461. Similarly, at its lateral edge which covers the second rail 20, the shell 45 is extended rearwardly along the second rail 20 by another longitudinal protuberance 452 This further protuberance 452 covers, at least upwardly and inwardly of the vehicle seat support, part of the second rail 20 and contributes, with a secondary flap 462 (see below) to protect the second rail 20. . Longitudinal outgrowth 452 r covers the front end of the secondary flap 462. The longitudinal protuberances 451, 452 have an interior face which is directed towards the interior of the vehicle seat support assembly and which covers the opening 13, 23 of the rail 10, 20 , and an upper face which covers the upper part of the rail 10, 20. This inner face may be oblique in particular if the opening 13, 23 of the rail 10, 20 opens obliquely upwards (with an angle relative to the 'transverse axis Y, as shown in the figures). Alternatively, this inner face can be vertical, in particular if the opening 13, 23 of the rail 10, 20 opens out horizontally in the XY plane.
    [0085] When the central module 30 and the footrest 40 are the furthest apart, the front edge of the first plate 35 and the rear edge of the shell 45 are located substantially at the same position along the axis. longitudinal X, with the shell 45 partially engaged under the first plate 35. When the central module 30 and the footrest 40 are brought together by sliding along the rails (10, 20), the rear part of the shell 45 passes under the first plate 35 and is covered, partially or entirely, by this first plate 35. Thus, the footrest 40 can be brought closer to the central module 30, which improves the ergonomics of the assembly . In addition, the passenger's feet can also rest on the shell 45 and do not risk interfering with the sliding of the footrest 40 or of the central module 30. In addition, the vehicle floor between the rails 10, 20 between the central module 30 and the longitudinal extension 42 being covered regardless of the relative position of the central module 30 and the footrest 40, this floor is protected from the arrival of foreign objects between the rails 10, 20 which could disturb the operation of the whole.
    [0086] The portion of each of the rails 10, 20 which is located between the central module 30 and the footrest 40 is covered by the aforementioned primary flap 361 and the secondary flap 461, which can be made in particular of plastic material and which make it possible to on the one hand, to protect these rails by preventing foreign bodies from entering the interior space of a rail 10, 20 and hampering its operation and on the other hand, to prevent injuries to users on the rails 10 , 20.
    [0087] A first embodiment of these shutters and their operating mechanism will now be described, for the first rail 10, with reference to FIGS. 12, 13, and 14. In this first embodiment, the primary shutter 361 and the secondary shutter 461 are integral with one another and fixed to the footrest 40. For example, the primary flap 361 can be supported by a primary frame 371 and the secondary flap 461 can be supported by a secondary frame 471 which is fixed to 'on the one hand, to the primary reinforcement and on the other hand, to the shuttle 431.
    [0088] The flaps 361, 461 are parallel to the open face of the first rail 10, that is to say oblique with respect to the transverse axis Y, in order to prevent the introduction of foreign bodies into the interior space of the first rail 10. The oblique flaps 361, 461 can be extended by a horizontal extension which covers the top of the first rail 10 in order to also protect upwards.
    [0089] FIG. 15 is a sectional view of the second rail 20 at the level of the secondary flap 462, which shows the attachment of this secondary flap 462 to the secondary frame 472.
    [0090] The front end of the secondary flap 462 may be partially covered by the extension 451 of the shell 45 and in the position where the footrest 40 is furthest from the central module 30, the rear end of the primary flap 461 is substantially at the same level as the front end of the extension 351, for example the rear end of the primary shutter 461 can be partially engaged under the front end of the extension 351.
    [0091] As the central module 30 and the footrest 40 move closer to each other, the primary flap 361 and then the secondary flap 461 slide under the extension 351 and the side edge of the first plate 35.
    [0092] It will be noted that in this first embodiment, the primary shutter 361 and the secondary shutter 461 could be replaced by a single shutter.
    [0093] We now describe a second embodiment of these shutters and their operating mechanism, for the first rail 10, with reference to Figures 16 and 17. In this second embodiment, the primary shutter 361 is fixed to the central module 30 and the secondary flap 461 is fixed to the footrest 40, these flaps being arranged to overlap.
    [0094] For example, the primary flap 361 can be carried by a primary frame 371 connected to the slider 513 and the secondary flap 461 can be carried by a secondary frame 471 connected to the shuttle 431. The connection of the primary frame 371 to the slider 513 can be an elastic connection (spring or other elastic link 381, allowing the flap 361 and its frame 371 to slide rearward in the longitudinal direction X relative to the slide 513) while the connection of the secondary frame 471 to the shuttle 431 can be a rigid link. As a variant, the connection of the primary armature 371 to the slide 513 can be a rigid connection while the connection of the secondary armature 372 to the shuttle 431 can be an elastic connection (spring or other elastic link 381 (spring or other, allowing the shutter 461 and its frame 471 to slide forward in the longitudinal direction X relative to the shuttle 431).
    [0095] Figures 16 and 17 show the central module 30 and the footrest 40 respectively in a position far apart from each other as far as possible and in a position close to each other as far as possible. When the central module 30 and the footrest 40 approach each other, the flaps 361, 461 overlap until they are almost completely covered, then the flap 461 and its frame 471 come into abutment against the flap 361 and the frame 371 and push the flap 361 and the frame 371 back against the elastic stress of the elastic link 381 (the movement would be similar with movement of the flap 461 forward in the case where the elastic link 381 would be between the frame 471 and the shuttle 431), allowing the shell 45 and the first plate 35 to come into contact with each other. When the central module 30 and the footrest 40 move away from each other, the flaps and their frames follow a reverse movement, the return of the flap 361 to the initial position being effected by the elastic bias of the elastic connection. 381.
    [0096] As a variant, the two flaps 361, 461 could be connected by elastic connections respectively to the slider 513 and to the shuttle 431 and mounted to slide in the longitudinal direction X with respect to the slider 513 and to the shuttle 431. In this case, the shutters 361, 461 do not need to overlap, they remain in axial abutment with each other and disappear respectively under the extensions 351, 451 when the central module (30) and the footrest (40) come closer to each other.
    [0097] It will be noted that the flaps 361, 461 could be devoid of reinforcements, in particular when they are formed with a geometry and / or a material giving them sufficient rigidity.
    [0098] The above descriptions of the shutter mechanism 361, 362 in the first embodiment and the second embodiment have been made for the first rail 10. The assembly being symmetrical with respect to a vertical plane (XZ) passing through its middle, the mechanism of the shutters is identical for the primary shutter 362 and the secondary shutter 462 which cover the second rail 20, and for their respective reinforcements 372, and where appropriate the elastic link 382. These last references are indicated in brackets on the relevant figures. Everything that has been described above also applies to the second rail 20.
    [0099] The primary reinforcements 371, 372 and the secondary reinforcements 471, 472 can be housed at least partially in the respective rails 10, 20 and slide longitudinally with respect to the respective rails 10, 20.
    [0100] In the above description, as illustrated in Figure 1, the first plate 35 is located above the rails 10, 20, and the rear part of the shell 45 slides under the first plate 35, so that the rear part of the shell 45 is located between the rails 10, 20 (in the horizontal plane containing the rails). Alternatively, the rear part of the shell 45 could slide above the first plate 35.
    [0101] The assembly further comprises an end module 80 which is fixed to the rear ends 11, 21 of each of the rails 10, 20. This end module 80 will now be described with reference to FIGS. 19 to 22. This module d 'end forms a transverse structure which secures together the rails 10, 20, which are also kept parallel by the central module 30 and the footrest 40 before mounting the seat support in the vehicle, which allows the mounting of the support of seat in the vehicle as a single module during vehicle construction.
    [0102] This end module 80 extends transversely along the Y axis from the rear end 11 of the first rail 10 to the rear end 21 of the second rail 20. The end module 80 comprises a box 83 provided with 'a cover 84. The box 83 is fixed at a right end to the rear end 11 of the first rail 10, and at its left end to the rear end 21 of the second rail 20. The adjectives “right” and “left” are defined with respect to the direction and direction of the longitudinal X axis, such that the right side is towards negative values of the transverse Y axis and the left side is towards positive values of the transverse Y axis Thus, in Figures 19 and 20, the first rail 10 is on the right of the longitudinal axis X, and the second rail 20 is on the left of the longitudinal axis X.
    [0103] The end module 80 has a first connector 81 which is connected with the first belt 851, and a second connector 82 which is connected with the second belt 852. These connectors are visible in figure 22. Their function is detailed below. .
    [0104] The end module 80 comprises a first belt 851 and a second belt 852, which are housed in part in the box 83. Each of these belts 851, 852 extends in a main direction, which is their length, and has a length. width and thickness. The first belt 851 is fixed by one of its ends 8514 to the end module 80 and by the other of its ends 8513 to the central module 30. For example, as illustrated in FIG. 22 (where the cover 84 is omitted), the end 8514 of the first belt 851 is fixed in the box 83 on its right side, extends to the left and is folded once on itself to return to the right side and exit through the right end of the box 83 in the first rail 10. Similarly, the end 8524 of the second belt 852 is fixed in the box 83 on its left side, extends to the right and is folded once on itself to return to the left side and exit through the left end of the box 83 in the second rail 20. Thus, a large part of the length of each of these belts (851, 852) is housed in the box 83, being folded back on itself or wound up . When the central module 30 slides from its rear position closest to the end module 80 which is shown in figure 19, towards its front position which is shown in figure 20, the first belt 851, the end of which 8513 is pulled by the central module 30 slides along the first rail 10. Likewise, the second belt 852, the end of which 8523 is pulled by the central module 30, slides along the second rail 20.
    [0105] The belts 851, 852 protect the interior spaces of the rails (10, 20) against the arrival of external foreign objects which could interfere with the sliding. The belts 851, 852 also have a function of supporting and guiding cables between the end module 80 and the central module 30 (see below).
    [0106] The first belt 851 and the second belt 852 are made of a material flexible enough to be folded back on itself in the end module 80 and sufficiently rigid to slide freely in the rails 10, 20. This rigidity is a function of the width. and the thickness of the belts 851, 852.
    [0107] For example, this material can be a metal. Alternatively, this material can be a polymer. For example, this material is an elastomer. In this case the belts 851, 852 can be overmolded on the cables 89.
    [0108] Advantageously, the end module 80 is attached to the rails 10, 20 in a removable manner. The assembly is therefore easily configurable and repairable. For example, this fixing is effected by snap-fastening. When attached, the right and left ends of the end module 80 attach to the rear end 11 of the first rail 10 and the rear end 21 of the second rail 20, respectively. The first belt 851 and the second belt 852 are then inserted on the first rail 10 and the second rail 20 respectively.
    [0109] The first belt 851 slides along the first rail 10 so as to cover the entire first opening 13 between the end module 80 and the central module 30. Thus, the width of the first belt 851 is equal to the width of the first. opening 13, measured in the plane (plane P1) in which this first opening 13 extends. Likewise, the second belt 52 slides along the second rail 20 so as to cover the entire second opening 23 between the end module 80 and the central module 30. Thus, the width of the second belt 852 is equal to the width of the second opening 23, measured in the plane (plane P2) in which this second opening 23 extends. For example, these two planes P1, P2 are vertical, that is to say perpendicular to the transverse axis Y. Alternatively, as shown in the figures, these planes P1, P2 are oblique (each of these planes contains the longitudinal axis X and makes an angle θ with the vertical axis Z, these two planes forming between them an angle "V" at the vertex equal to 2 ∙ θ). These planes and the angle θ are illustrated in Figure 22. For example the "V" is directed upwards (positive direction of the vertical axis Z).
    [0110] The first opening 13 has a lower guide 16 along its lower edge, and has an upper guide 17 along its upper edge. For example, these guides are C-shaped slides. The first belt 851 has along its edge. lower edge a lower bead 8516, and has along its upper edge an upper bead 8517. The lower bead 8516 slides in the lower guide 16, and the upper bead 8517 slides in the upper guide 17. This sliding takes place when the central module 30 is moved relative to end module 80. These guides (16, 17) and these beads (8516, 8517) are visible in Figure 22.
    [0111] Likewise, the second opening 23 has a lower guide 26 along its lower edge, and has an upper guide 27 along its upper edge. For example, these guides are C-shaped slides. The second belt 852 has the along its lower edge a lower bead 8526, and has along its upper edge an upper bead 8527. The lower bead 8526 slides in the lower guide 26, and the upper bead 8527 slides in the upper guide 17. This sliding s' performs when the central module 30 is moved relative to the end module 80. These guides (26, 27) and these beads (8526, 8527) are visible in figure 22, and in figure 21.
    [0112] The first belt 851 comprises a support 8515 which is suitable for guiding cables 89 as far as the central module 30. Likewise the second belt 852 comprises a support 8525 which is suitable for guiding cables 89 as far as the central module 30. These cables 89 are visible in figure 21. The supports (8515, 8525) are elements which are fixed on the belts (851, 852), or which come from molding. These elements run the full length of the belts (851, 852). Alternatively, these elements are distributed regularly along the belts (851, 852). The cables 89 on the first belt 851 are connected at one end to the first connector 81 of the end module 80 then enter the first belt 851 at its first end 514, and run along the first belt 851 to its second end 8513 for be connected to the central module 30. The cables 89 on the second belt 852 are connected at one end to the second connector 82 of the end module 80 then enter the second belt 852 at its first end 8524, and run along the second belt 852 to 'at its second end 8523 to be connected to the central module 30.
    [0113] For example, these elements have longitudinal holes (that is to say in the main direction of the belts 851, 852) through which the cables 89 can pass. The support 8525 of the second belt 852 is visible in figure 18.
    [0114] The vehicle seat support which has just been described is in the form of a ready-to-use module, which can optionally be attached in one piece with all its elements pre-assembled or only some of its elements. pre-assembled) in the vehicle under construction. The electrical connection (of power and advantageously of control) to the vehicle, of the actuation systems 50, 60 and advantageously of all the electrical elements of the seat assembly, can be done in a single operation during the assembly of the assembly. seat on the vehicle floor P. This electrical connection can be made in a single operation, either with a single connector (not shown), or with several connectors (for example a power connector and a low current connector) (not shown) provided for example at the level of the rear module 80.
