    detailed description
    In the different figures, the same references designate identical or similar elements. For the sake of brevity, only the elements which are useful for understanding the embodiment described are shown in the figures and are described in detail below.
    In the following description, when reference is made to qualifiers of absolute position, such as the terms "front", "rear", "top", "bottom", "left", "right", etc., or relative, such as the terms "above", "below", "upper", "lower", etc., or to qualifiers of orientation, such as "horizontal", "vertical", etc., it is done reference, unless otherwise specified, to the orientation of the figures or of a seat in its normal position of use.
    Figure 1 schematically shows a motor vehicle seat assembly 10 comprising a motor vehicle seat 12 mounted on a slide mechanism 13 for fixing the vehicle seat device 12 on the floor 11 of a motor vehicle. The floor 11 is for example formed by the chassis of the motor vehicle. The motor vehicle seat 12 is here a rear seat.
    In the following, the longitudinal direction X is understood to mean the longitudinal direction of the seat 12. The longitudinal direction of the seat 12 is considered to be the same as the longitudinal direction of the motor vehicle in which the seat 12 is mounted. This longitudinal direction X corresponds to the normal direction of advance of the vehicle. The transverse direction Y is the transverse direction of the seat 12. The transverse direction of the seat 12 thus corresponds to the transverse or lateral direction of the motor vehicle. This transverse direction corresponds to a direction perpendicular to the normal direction of advance of the vehicle. Finally, the vertical direction Z is a vertical direction of the seat 12, perpendicular to the longitudinal and transverse directions.
    The seat 12 comprises a seat 14, with a seat frame 15, and a back 16, with a back frame 17. The back frame 17 is pivotally mounted relative to the seat frame 15 around a first transverse axis Al, parallel to direction Y.
    In the following, one side of the car seat 12 is described, it being understood that the two sides of the seat 12 are substantially identical.
    The backrest frame 17 is also pivotally mounted about a second transverse axis A2 with respect to a flange 18. In the present case, an articulation mechanism is interposed between the flange 18 and the backrest frame 17. The articulation mechanism 20 is for example a discontinuous mechanism, that is to say it is adapted to adjust the angular position of the backrest frame 17 relative to the flange 18 in a finite number of discrete positions. The articulation mechanism 20 can advantageously have a "disengaged" mode for folding down the back frame 17, for example in the position shown in FIG. 2, as opposed to the "engaged" mode in which the articulation mechanism allows adjustment of the inclination of the backrest frame 17. Preferably, the articulation mechanism 20 is electrically controlled. Thus, the adjustment of the inclination of the backrest frame 17 is carried out by means of control buttons of the articulation mechanism 20. To do this, the articulation mechanism 20 may for example comprise a drive motor. The drive motor can then be controlled using the control buttons. Alternatively, the articulation mechanism 20 can in particular be a “hook-cable” type system, comprising a cam and having an angular adjustment range in which the articulation mechanism is not locking (disengaged position), and a another adjustment range, distinct from the first, in which the articulation mechanism can be locked (engaged position). For example, the articulation mechanism must be unlocked in order to be able to adjust its angular position, the adjustment being carried out while keeping the articulation mechanism unlocked. Then, once the satisfactory angular position has been reached, the articulation mechanism 20 is again locked.
    In the example illustrated, the flange 18 is connected to a support 21 of the seat, by means of first and second connecting rods 22, 24. Each connecting rod 22, 24 is pivotally mounted in the vicinity of a first end on the flange 18 around 'a third and a fourth transverse axis A3, A4 respectively. Each connecting rod 22, 24 is also pivotally mounted, in the vicinity of its second end, on the support 21, around a fifth and a sixth transverse axis A5, A6 respectively.
    An actuator can advantageously be provided for adjusting the angular position of the connecting rods 22, 24 relative to the support 21 of the seat. For example, a jack, in particular an electric jack, may be provided between the support 21 of the seat and one of the connecting rods 22, 24. In this case, the jack is advantageously mounted free to rotate about axes transverse to each of its ends, relative to the support 21, on the one hand, and to the connecting rod 22, 24, on the other hand.
    Here, a third connecting rod 26 connects the seat frame 15 and the support 21. This third link 26 is mounted to rotate freely around a seventh transverse axis A7 relative to the seat frame 15 in the vicinity of a first end. In the vicinity of its second end, the third connecting rod 26 is here mounted to rotate freely relative to the support 21, around an eighth transverse axis A8.
    Furthermore, the seat 12 includes a headrest 28 with a headrest frame 30. The headrest frame 30 is mounted on the backrest frame 17. For example, the support frame -head 30 can be moved relative to the back frame 17, especially in translation, to adjust the height of the headrest 28.
    Finally, in the example illustrated, the support 21 of the seat forms a rail, in this case the movable rail, of the slide mechanism 13, the support 21 being received in a rail 32, in this case the fixed rail, of the slide mechanism 13, fixed to the floor 11. Thus, the slide mechanism 13 makes it possible to adjust the longitudinal position of the seat 12 in the vehicle.
    As illustrated in Figures 1 to 3, the seat assembly 10 which has just been described can in particular take three distinct positions, corresponding to three different uses.
    In a first position, called "deployed", illustrated in FIG. 1, the seat 12 is in a position making it possible to receive an occupant of the seat 12. In this position, the back frame 17 and the seat frame 15 forms an angle substantially equal to 90 ° or even greater than 90 °. For example, the angle between the back frame 17 and the seat frame 15 is greater than or equal to 80 °, preferably greater than or equal to 85 ° and / or less than or equal to 120 °, preferably less or equal to 115 °.
    In this deployed position, the first and second connecting rods 22, 24 are in a low position. The first and second connecting rods 22, 24 can then form a substantially zero angle, for example less than 5 °, with the support 21 of the seat 12.
    On the contrary, the third connecting rod 26 is in a raised position, the angle between the third connecting rod 26 and the support 21 of the seat here being substantially equal to 90 °. For example, the angle between the third connecting rod 26 and the support 21 of the seat is greater than or equal to 60 °, preferably greater than or equal to 70 ° and / or less than or equal to 130 °, preferably less than or equal to 110 °. Thus, the seat frame 15 is in a high position, that is to say at a distance from the support 21 of the seat. Above all, the seat frame 15 is then at a distance from the floor 11 of the motor vehicle, so that the seat 10 is in a position allowing an occupant to sit there comfortably.
    This position is maintained for example by blocking the actuator for adjusting the angular position of the first and second connecting rods 22, 24 in its corresponding position (in particular in its corresponding length).
    Alternatively or additionally, this “deployed” position is maintained by blocking the position of the flange 18 on the support 21, the rail 32 of the slide mechanism 13 or the floor 11 of the motor vehicle, by means of a lock 33. The lock 33 can also cooperate with a bar integral with the support 21, the rail 32 or the floor 11.
    In this position, the inclination of the backrest frame 15 can be adjusted by means of the articulation mechanism 20. Thus, there are in fact many deployed positions.
    In addition, for safety reasons, the angular position of the third connecting rod 26 can be locked in its corresponding angular position, by means of any blocking device accessible to those skilled in the art. In particular, a blocking latch can be provided.
    The articulation 20 can be locked in the position of FIG. L In this deployed position of FIG. 1, the back of the backrest frame 17 can extend in a direction B.
    FIG. 2 illustrates a “storage” position of the seat 12.
    In this storage position, intended to increase the space in the boot, for example, the position of the first and second connecting rods 22, 24 is unchanged. However, the angular position of the backrest frame 17 has been modified, so that the backrest frame 17 is folded down, in this case in a substantially horizontal position, and is placed opposite the seat frame 15. To reach this position of the back frame 17, for example, we went into the disengaged position of the articulation mechanism 20 and the back frame 17 was folded down. Thus, preferably, the articulation mechanism 20 is preferably free, so that the backrest 16 is a priori mobile relative to the seat 14.
    In the example illustrated, the back of the backrest frame 17 extends in a direction Bl forming with the axis B, corresponding to the deployed position, an angle βΐ for example between 100 and 105 °, advantageously between 101 and 104 °.
    The folding of the back frame 17 is accompanied by a displacement of the seat frame 15 and of the third connecting rod 26. In the storage position, in fact, the third connecting rod 26 is more inclined relative to the support 21 only in the deployed position. In other words, the angle between the third link 26 and the support 21 is greater in the storage position than in the deployed position. This brings the seat frame 15 closer to the support 21 and / or the floor 11. It is then possible to maintain the position of the seat by blocking the angular position of the third connecting rod 26 relative to the support 21. Again, all blocking system accessible to those skilled in the art can be implemented, in particular a blocking latch.
    In this storage position, the latch 33 is preferably always in its position for locking the flange 18 relative to the support 21.
    Finally, in the so-called console position, illustrated in FIG. 3, the first and second connecting rods 22, 24 are pivoted relative to their positions corresponding to the deployed and storage positions of the seat, described above, in order to raise the flange 18 relative to to the support 21 of the seat and therefore the floor 11. To do this, the first and second connecting rods 22, 24, the support 21 and the flange 18 can for example substantially form a deformable parallelogram. The lifting of the flange 18 with respect to the support 21 is thus controlled by the actuator for adjusting the angular position of the first and second connecting rods 22, 24. In this console position, the back frame 17 is always substantially opposite. seat frame screw 15.
    To move into the console position, the latch 33 is previously unlocked.
    To hold the backrest frame 17 in position, the articulation mechanism 20 is in an angular locking position of the backrest frame 17 relative to the flange 18. For example, this backrest frame position 17 corresponds to that in which the back of the backrest frame 17 is substantially horizontal. By substantially horizontal is meant here forming an angle of plus or minus 10 ° relative to the horizontal direction. Thus, in this position, the backrest frame 17 can advantageously be implemented as a console, table or armrest, in particular, for occupants of vehicle seats adjacent to seat 12.
    In this so-called console position, the angular position of the third connecting rod 26 relative to the support 21 can also be blocked. Any device for locking in angular position of the third connecting rod 26 relative to the support 21, accessible to those skilled in the art can be envisaged. In particular a blocking latch can be implemented.
    In the position illustrated in FIG. 3, by way of example, the angle between the direction B2 of the back of the backrest frame 17 and the direction B of this same back of the backrest frame 17, in the position deployed, forms an angle β2, which can for example be greater than or equal to 100 °, preferably greater than or equal to 107 ° and / or less than or equal to 115 °, preferably less than or equal to 110 °. The angle β2 is here substantially equal to 108 °, more precisely equal to 108.75 °.
    In addition, as is more particularly visible in FIG. 4, the seat 12 is provided, on its back 16, with a device 34 for a retractable shelf, the shelves 42 of which are deployed in FIG. 4.
    This retractable shelf device 34 is described in more detail below, with reference to FIGS. 5 to 8.
    The retractable shelf device 34 firstly comprises a frame 36, fixed relative to the backrest 16 of the seat 12. According to a variant not shown, the frame 36 is formed by the backrest frame 17. The frame 36 is notably illustrated in Figure 8, where we can see that the frame 36 has a substantially T-shaped. The frame 36 is substantially planar. The frame 36 has a first pair of straight slots 38a, 38b, extending over substantially the entire length of the frame 36. The frame 36 also has a second pair of curved slots 40a, 40b. The slots 40a, 40b have a first portion, close to the straight slots 38a, 38b, which extends substantially parallel to the slots 38a, 38b, and a second portion which gradually moves away from the straight slots 38a, 38b, towards the exterior of the frame 36. The slots 40a, 40b thus extend from a first end in the vicinity of which they are substantially parallel, towards a second end in the vicinity of which they diverge.
    The retractable shelf device 34 further comprises two retractable shelves 42. These retractable shelves 42 have here a substantially rectangular shape, with rounded angles. Each shelf 42 also has two through openings 44, 46: a first opening 44 is arranged in the vicinity of a corner of the shelf 42; and a second opening 46 is arranged at a distance from the angle where the first opening 44 is made, and preferably at a distance from the edge 47 of the shelf 44, greater than the distance between the first opening 44 and the edge 47 of tablet 42.
    The retractable tablet device 34 also comprises a device 48 for controlling the retraction and deployment of each tablet 42, independently of one another. The control device 48 is here electrical. The control device 48 is notably visible in FIGS. 5 and 6.
    The part of the control device 48 enabling the deployment or retraction of a shelf 42 is described below. To control the deployment or retraction of the two shelves 42, independently of one another, the control 48 may thus include the means described below, in duplicate, as shown in Figures 5 and 6, in particular.
    The control device 48 firstly comprises an electric motor 50, for example fixed to the frame 36. This electric motor 50 rotates an endless screw 52, in this case by means of a reduction device 54 The endless screw 52 is arranged opposite one of the two rectilinear slots 38a, 38b of the frame 36.
    On the endless screw 52 is fixed a slider 56 so that the rotation of the endless screw 52 causes a translation of the slider 56 relative to the endless screw. For example, the slide 56 has a housing for receiving a nut mounted on the worm 52. The slide 56 can for example be prevented from pivoting around the axis of rotation of the worm 52 by being received in one of the straight slots 38a, 38b. In this case, the edges of the rectilinear slot 38a, 38b block the rotation of the slider 56, which consequently moves in translation in the rectilinear slot 38a, 38b, which receives it. The slide 56 is thus guided in translation by the rectilinear slot 38a, 38b.
    The slide 56 is also received in the first opening 44 of one of the two shelves 42. The shelf 42 is free to rotate relative to the slide 56, in the plane of the shelf 42.
    Finally, a pin 58 is fixed to the tablet 42, free to rotate relative to the tablet 42. The pin 58 is moreover received in a slot 40a, 40b, the pin 58 being able to pivot in the slot 40a, 40b.
    According to the example illustrated, the retractable shelf device 34 also comprises a shell 60. The shell 60 essentially has an aesthetic function. This shell 60 can be substantially flat to allow the use of the backrest 16 of the seat 12 as a table. The shelves 42 preferably extend between the frame 36 and the shell 60.
    The operation of the retractable shelf device 34 is described below. The electric motor 50 causes the rotation of the endless screw 52. This rotation of the endless screw 52 causes the translation of the slider 56 along the endless screw 52. The translation of the slider 56 induces a movement of the angle of the shelf 42 in the vicinity of which the first opening 44 is made. The distance between the two openings 44, 46 in the shelf 42 being fixed, the movement of the angle of the shelf 42 also causes a displacement of the shelf 42 comprising a translation along the endless screw 52 and a rotation around the first opening 44. The shape of the slot 40a, 40b then makes it possible to guide the tablet between a deployed position, visible in FIG. 4, and a retracted position corresponding to the Figures 1 to 3. It should be noted here that the displacement of the shelves 42 is carried out substantially in the plane of these shelves 42. To do this, in particular, the shelves 42 can be guided in their movement s between the frame 36 and the shell 60. Thus, the retractable shelf device 34 is particularly compact. The retractable shelf device 34 can in particular be received in whole or in part between two uprights of the backrest frame 17.
    Figures 9 to 12 illustrate an example of implementation of the seat assembly 10 of Figures 1 to 4.
    FIG. 9 thus schematically illustrates a motor vehicle 100, comprising two front seats 102, 104 aligned in a transverse direction, and three rear seats 12, 106, 108, the central seat of which is a seat 12 of a seat assembly 10, as previously described. The rear seats 12, 106, 108 are offset in the longitudinal direction X, with respect to the front seats 102, 104.
    According to the example illustrated, the shelves 42 of the seat 12 can be used by occupants of the front seats 102, 104. To do this, as illustrated in FIG. 10, the front seats 102, 104 are pivoted about a substantially axis respective vertical A102, A104, so that the two front seats 102, 104 are oriented in converging directions, preferably without facing each other, as illustrated in FIG. 10. This frees up space between the two front seats 102 , 104, space which allows the central rear seat 12 to pass between the two front seats 102, 104 or, at the very least, the backrest 16 of said central rear seat 12. The central rear seat 12 is then in a position where the backrest is folded down, in particular in the console position of the seat 12. If necessary, the longitudinal position of the central rear seat 12 relative to the front seats 102, 104 can be adjusted by translation of at least one of the seats front 102, 104 and said central rear seat 12.
    In addition, the front seats 102, 104 may be in a position in which their backrest is inclined relative to their seat, for example by an angle greater than the angle of inclination of the backrest in a driving position, greater angle corresponding to a rest position of the occupants of the front seats 102, 104.
    The back 16 of the central rear seat 12 can then be used as a table by the occupants of the front seats 102, 104.
    Here, furthermore, the central rear seat 12 being provided with a retractable shelf device 34, the shelves 42 can then be deployed, as illustrated in FIG. 12. The shelves 42 then deploy in front of the front seats 102, 104. The shelves 42 can then be used by the occupants of the front seats 102, 104.
    As a variant, however, the shelves of the central rear seat 12 can be used by the occupants of the rear seats 104, 106. To do this, for example, the central rear seat 12 is not moved longitudinally in the direction of the front seats 102, 104. In this case, the backrest 16 of the central rear seat 12 can extend entirely or start behind the front seats 102, 104.
    The example of a vehicle seat assembly described above is capable of numerous variants accessible to those skilled in the art.
    In particular, the seat support can take many forms. Thus, according to a particular example, the seat support is formed by the floor of the passenger compartment of the motor vehicle equipped with the seat.
