    [0002] Longitudinal displacement system for a vehicle seat, vehicle seat assembly and vehicle including the system
    [0004] Technical sector
    [0006] The present invention concerns, in a first aspect, a longitudinal movement system for a vehicle seat, which comprises a positioning system arranged at a height greater than that of a longitudinal guide on which a seat base slides and the seat supported by it.
    [0008] A second aspect of the present invention concerns a seat assembly comprising the longitudinal displacement system of the first aspect of the invention and a vehicle seat.
    [0010] A third aspect of the present invention concerns a vehicle comprising the seat assembly of the second aspect mounted on a floor thereof.
    [0012] Prior state of the art
    [0014] Longitudinal displacement systems for a vehicle seat are known, comprising the characteristics of the preamble of claim 1 of the present invention, that is:
    [0016] - at least one longitudinal guide configured and arranged to be fixed to the floor of a vehicle;
    [0018] - a seat base configured and arranged to be coupled in a guided manner to said longitudinal guide, to slide along the longitudinal guide according to a longitudinal displacement in a direction X, in both directions; and
    [0020] - a positioning system configured and arranged to selectively position said seat base in each of a plurality of positions that can be adopted along said longitudinal movement, and to block the longitudinal movement of the seat base in the position in whichever is positioned.
    [0022] One of such known systems is described in patent US9688164B2, which includes at least two longitudinal guides, and the seat base is supported by cross members whose ends are guided by such longitudinal guides. In such a known system the positioning system is implemented in the longitudinal guides themselves, for example in the form of zippers defined therein and corresponding gears attached to the ends of the crossbars.
    [0024] The fact that in the US9688164B2 system the longitudinal guides themselves, which are the ones that support the weight of the seat base and the seat supported by it, are the ones that implement the positioning system, makes the components of the positioning system positioning (racks and gears) are subject to great mechanical stress and the force that must be exerted to move from one position to another is considerable.
    [0026] Likewise, the arrangement proposed in such patent, where both the guidance and the positioning are at the ground level of the vehicle, or slightly above it, makes the accessible space that remains available under the seat is very small, which can be necessary, for example, for a passenger of the vehicle to insert their feet.
    [0028] Likewise, for seats that are designed with greater height to provide such space below it, for systems such as that of patent US9688164B2, it would be necessary to have actuating means that would have to travel a long way, go down a lot, from the actuator of the same until almost level with the ground of the vehicle.
    [0029] On the other hand, in the system proposed in US9688164B2, when having access to the base of the seat, small objects can get in the way that obstruct the guiding and positioning mechanism, even the user could insert the foot and crash with any part of the mechanism, get dirty if some lubricant is used, etc.
    [0031] It appears, therefore, necessary to offer an alternative to the state of the art that covers the gaps found in it, by providing a longitudinal displacement system for a vehicle seat that does not suffer from the above-mentioned drawbacks, allowing a positioning that requires exerting only a small force, as well as having more space under the seat that is accessible to a user.
    [0033] Explanation of the invention
    [0035] To this end, the present invention concerns, in a first aspect, a longitudinal displacement system for a vehicle seat, comprising:
    [0037] - at least one longitudinal guide configured and arranged to be fixed to the floor of a vehicle;
    [0038] - a seat base configured and arranged to be coupled in a guided manner to said longitudinal guide, to slide along the longitudinal guide according to a longitudinal displacement in a direction X, in both directions, that is to say forwards and backwards according to the direction of travel; and
    [0040] - a positioning system configured and arranged to selectively position said seat base in each of a plurality of positions that can be adopted along said longitudinal movement, and to block the longitudinal movement of the seat base in the position in the one that is positioned;
    [0042] Unlike the systems known in the state of the art, in the longitudinal displacement system of the first aspect of the present invention, characteristically, the aforementioned positioning system comprises:
    [0044] - at least one structural member configured and arranged to be fixed to said vehicle floor, and comprising positioning configurations arranged along said structural member, which is at least one, at a height greater than that of the longitudinal guide, with respect to the ground of the vehicle;
    [0046] - a locking element attached to the seat base to move longitudinally together with it, and configured and arranged to adopt:
    [0048] - a locking position in which the locking element cooperates with a respective one of said positioning configurations to lock the longitudinal movement of the seat base in the position in which it is positioned, and
    [0050] - an unlocking position in which said longitudinal displacement is unlocked;
    [0052] and
    [0054] - actuating means configured and arranged to actuate the locking element to adopt said locking position or said unlocking position.
    [0055] According to an exemplary embodiment, said blocking element comprises:
    [0056] - a first portion attached to the seat base; and
    [0058] - a second portion comprising at least one locking configuration, said second portion being movable with respect to the first to adopt said locking position, wherein said locking configuration cooperates with a respective one of said positioning configurations to block movement longitudinal of the seat base in the position in which it is positioned, and said unlocking position, in which said locking configuration, which is at least one, does not cooperate with any of the positioning configurations allowing longitudinal displacement of the seat base .
    [0060] For an exemplary embodiment, the at least one longitudinal guide and the seat base are configured and arranged so that, once coupled, the longitudinal guide supports the entire weight of the seat base and of a possible seat supported by it.
    [0061] According to a preferred embodiment, the system of the first aspect of the invention comprises a single longitudinal guide, which together with the fact that the positioning system is not implemented by such a single longitudinal guide, which constitutes the most voluminous element of the system, reduces the space required for guidance and positioning considerably compared to the state of the art.
    [0063] The fact that, for said embodiment, the seat load rests exclusively on the longitudinal guide and not on the structural member (s) of the positioning system is also advantageous. By not having to bear weight, the action on the locking element requires much less effort, facilitating its action.
    [0065] Advantageously, the only longitudinal guide is arranged in a centered position, according to a Y direction orthogonal to the X direction, with respect to the seat base, being coupled thereto, and to a possible seat supported by the seat base.
    [0066] For an implementation of said embodiment, the structural member or each of the structural members, in the event that there is more than one, is configured and arranged so that, once fixed to the vehicle floor, it is located to one side. of the only longitudinal guide, according to the Y direction.
    [0068] According to an example of embodiment, the system of the first aspect of the present invention comprises two structural members, configured and arranged so that, once fixed to the vehicle floor, the only longitudinal guide is located between the two structural members according to the direction And, advantageously adjacent to it, that is to say at a small distance from it (a few centimeters).
    [0070] For an implementation of said embodiment, the system of the first aspect of the present invention comprises two locking elements such as the one described in this document, each one configured to cooperate with the positioning configurations of a respective one of said two structural members, to provide respective locking positions, and to stop doing so to provide corresponding unlock positions. Preferably, such two locking elements are mechanically integral (for example, forming two parts of a single piece) to move in unison evolving from the locking positions to the unlocking positions, and vice versa.
    [0072] According to an exemplary embodiment, the structural member or each of the structural members, in the event that there are more than one, is a wall with a lower end configured to be fixed to the vehicle floor and an upper end comprising the aforementioned positioning configurations arranged along it.
    [0074] Preferably, said wall or each of the walls, in the event that there is more than one, is configured and arranged so that, once fixed to the vehicle floor, it runs in parallel with the longitudinal guide (s) .
    [0076] With the present invention it is sought that the seat has a sufficient height so that there is enough space for the user to insert the feet. So that the positioning elements do not have to move to the vehicle floor, the wall (s) extend vertically in Z, having the locking element (s) closest to the actuator and the base of the seat. Another advantage that the design of the vertical walls brings with it is that it protects the longitudinal guide and its assembly from objects falling nearby or the user entering this area by mistake.
    [0078] According to an exemplary embodiment, each of the positioning configurations comprises one or more slits, and the locking configuration comprises one or more teeth configured and arranged to selectively engage, in the locking position, with the one or more slits. of each of the positioning configurations, and disengage from the same (s) in the unlock position.
    [0080] According to a preferred embodiment, the first portion of the locking element is hingedly fixed to the seat base along an articulation axis, so that the second portion pivots around the articulation axis to evolve from the position. from lock to unlock, and vice versa.
    [0082] Alternatively, for other embodiments, the fixing of the locking element to the seat base is different from that indicated in the previous paragraph, so that at least the second portion of the locking element evolves from the locking position to that of unlocking, and vice versa, according to another type of displacement, for example linear.
    [0083] According to an exemplary embodiment, the locking element comprises an elongated piece, where the first portion is a first end portion of said elongated piece and the second portion is or projects from a second end portion of the elongated piece.
    [0085] Advantageously, the locking element is configured and hingedly fixed to the seat base so that the pivoting movement of the second portion thereof runs along a plane parallel to the wall or walls that constitute the structural member or members.
    [0087] For an exemplary embodiment, the aforementioned elongated piece is an L-shaped piece, with a larger segment that, in the assembly situation, runs adjacent to the wall closest to it, and a smaller segment that projects from a end of the larger segment in the direction of said wall, transversely with respect to it (orthogonally for the case of an L-shape with segments that form a right angle, or not necessarily orthogonally if the segments do not form a perfectly right angle). The locking configuration is included in said minor segment, so that it can cooperate with the positioning configurations.
    [0089] According to an exemplary embodiment, the actuating means comprise an actuator (such as a pushbutton) connected by a kinematic chain to the second portion of the locking element to move the second portion between the locking and unlocking positions, and vice versa.
    [0091] According to a preferred implementation of said embodiment, the kinematic chain comprises a traction cable with one end attached to the second portion of the locking element and an opposite end attached to the actuator, where the traction cable is configured to move the second portion to the unlock position by pulling the traction cable when actuating the actuator.
    [0093] According to a variant of said implementation, the actuating means comprise a compression spring interposed between a region of the seat base, or of a part fixed to it, and the second portion of the locking element to exert a force against it. to carry or maintain it in the locking position, so that to carry out the movement of the second portion to the unlock position, a traction force must be applied with the traction cable, which exceeds that exerted by said spring Of compression.
    [0094] According to an alternative embodiment, the actuating means comprise an actuator and a motor operatively connected to the second portion of the locking element to automatically move it between the locking and unlocking positions, and vice versa, when the actuator is actuated.
    [0096] For another alternative embodiment, the actuating means comprise an actuator and an electromagnet configured and arranged so that when activated, when actuating the actuator, it magnetically attracts the second portion of the locking element, which is ferromagnetic or comprises a ferromagnetic element, bringing it to the locked or unlocked position.
    [0098] For an exemplary embodiment, the system of the first aspect of the present invention comprises a support plate to which the longitudinal guide (s) and the structural member (s) are attached. , the support plate being configured and arranged to be fixed to the floor of the vehicle and with it to the elements fixed to it.
    [0100] In a second aspect, the present invention concerns a seat assembly for a vehicle, comprising the longitudinal displacement system of the first aspect and a seat fixed to the seat base to be supported by it.
    [0102] A third aspect of the present invention concerns a vehicle, generally motorized, comprising the seat assembly of the second aspect mounted on a floor thereof. Preferably, the vehicle comprises two such seat assemblies, one for the driver and the other for the passenger sitting next to him.
    [0103] Brief description of the drawings
    [0105] The foregoing and other advantages and characteristics will be more fully understood from the following detailed description of some embodiments with reference to the attached drawings, which should be taken by way of illustration and not limitation, in which:

    [0109] Figure 3 shows through a perspective view taken from the opposite side to that of Figure 2, also the system and seat assembly of the present invention, for the same example of embodiment, with its components assembled, but having omitted one of the walls, in order to allow the elements arranged behind it to be appreciated more clearly.
    [0111] Figure 4 is a front elevation view of the system and seat assembly of the present invention, for the same embodiment of Figures 2 and 3, with all its components assembled and illustrated.
    [0113] Detailed description of some examples of realization
    [0115] An example of embodiment of the longitudinal displacement system of the first aspect of the present invention and of the seat assembly of the second aspect (Figures 2 to 4) is illustrated in the attached Figures.
    [0117] As can be seen in the Figures, the system of the first aspect of the invention comprises, for the illustrated embodiment:
    [0119] - a support plate F to be fixed to the floor of the vehicle, and with it to the elements fixed to it;
    [0121] - a single longitudinal guide G fixed to the support plate F;
    [0123] - a seat base B with a lower part Bc that is coupled in a guided manner to the only longitudinal guide G, to slide along it according to a longitudinal displacement in a direction X, in both directions; and
    [0125] - a positioning system to selectively position the seat base B in each of a plurality of positions that can be adopted along its longitudinal displacement, and to block the longitudinal displacement of the seat base B in the position in the that is positioned.
    [0127] It can be seen in the Figures how the single longitudinal guide G is arranged in a centered position, according to a Y direction orthogonal to the X direction, with respect to the seat base B and to a seat A supported by the seat base B.
    [0129] For the illustrated embodiment, the positioning system comprises two walls P1, P2, arranged side by side of the single longitudinal guide G (according to direction Y), in parallel with it, each of which is provided with a lower end P1i, P2i fixed to the support plate F, and an upper end P1s, P2s comprising positioning configurations, in particular grooves H arranged along it (like spaces between the teeth of a rack), at a height greater than that of the longitudinal guide G, with respect to the vehicle floor, and in this case to the support plate F. Thus, the only longitudinal guide G is located between the two structural members P1, P2 according to the Y direction.
    [0131] Alternatively, for an exemplary embodiment not illustrated, the support plate F can be dispensed with and both the single longitudinal guide G and the walls P1, P2 fixed directly to the floor of the vehicle.
    [0133] The positioning system further comprises two locking elements L (for a non-illustrated embodiment the system only comprises one such locking element L) attached to the seat base B, in particular to the lower portion Bc, to move longitudinally together with the same, and configured to adopt respective locking / unlocking positions, to lock / unlock the longitudinal movement of the seat base B in the position in which it is positioned.
    [0135] The two locking elements L are mechanically integral, forming, for the illustrated embodiment, two parts of a single piece CL to move in unison evolving from the locking positions to the unlocking positions, and vice versa.
    [0137] As can be seen especially in Figure 1, each locking element L comprises:
    [0138] - a first portion L1 hingedly fixed, along an articulation axis E, to the seat base B, in particular to a middle part Bb thereof (by inserting the bolt Ja into the aligned holes Jb of the part J fixed to the middle part Bb of the seat base B);
    [0140] - a second portion L2 comprising a locking configuration, and which is displaced by pivoting around said articulation axis E along a plane parallel to the adjacent wall P1, P2, to evolve from the locking position to the unlocking position, and vice versa.
    [0142] For the illustrated embodiment, each locking configuration comprises teeth D, in this case three, which selectively engage, in the locked position, with three corresponding slots H of each of the positioning configurations, and disengage from the same when evolving to the unlock position.
    [0144] For the illustrated embodiment, to move the seat base B from one longitudinal position to another contiguous one, it is only necessary that the three teeth of each locking element L disengage from three corresponding slots H, and if the displacement is very small, they re-crimp in two of the same slits H plus in a third adjacent to them.
    [0146] Each locking element L comprises an elongated L-shaped piece, with a larger segment Sa that, in the assembly situation, runs adjacent to the wall P1, P2, and a smaller segment Sb. The first portion L1 of the locking element lock L is a first end portion of the major segment Sa of the elongated piece and the second portion L2 forms part of the minor segment Sb.
    [0148] As can be seen in particular in Figure 1, the minor segment Sb projects from one end of the major segment Sa in the direction of the adjacent wall, orthogonal to it.
    [0150] The locking configuration is included in the minor segment Sb, so that it can cooperate with the positioning configurations, that is, engaging the teeth d in the slots H, to lock the longitudinal movement of the seat base B in the position in the one that is positioned,
    [0152] Advantageously, the single longitudinal guide G supports the entire weight of the seat base B and of a possible seat A supported by it.
    [0154] The positioning system also comprises actuation means which, for the illustrated embodiment, as can be seen in particular in Figures 1 and 2, comprise an actuator T, in particular a push button arranged under the seat A (in an accessible position for the user), joined by means of a traction cable C (such as a Bowden cable or similar) to the second portion L2, or semi-free end, of one of the locking elements L, in particular the one with the through hole Sbh , which is traversed by one end of the traction cable C to which a stop Ct has been fixed to prevent the cable C from coming out of the hole Sbh and to push the second portion upwards (according to the position illustrated) L2 (or minor segment Sb), moving it (and with it the second portion L2 of the other locking element L) to the unlocking position, by pulling the traction cable C when actuating the actuator T. Other types of end connection cable Traction to the second portion L2 that dispenses with said stop Ct are also possible.
    [0156] As can be seen in the Figures, the actuating means comprise a compression spring R interposed between a piece Z, which guides the traction cable C and which is fixed to an upper part Ba of the seat base B, and the second portion L2 of the locking element L, to exert a force against it that takes or maintains it in the locked position, so that to carry out the displacement in Pivoting the second portion L2 to the unlocking position, a traction force must be applied with the traction cable C, which exceeds that exerted by said compression spring R.
    [0157] Alternatively, such a spring R can be dispensed with, and let gravity be responsible for moving the second portion L2 towards the locked position when pulling with the traction cable C.
    [0158] For the illustrated embodiment, a locking position is adopted when the user does not actuate the actuator T, so that the locking element L is in the locking position, with at least one (three, for the illustrated embodiment) of its projections / teeth D crimped into a slot H, so that the X offset of the seat is blocked.
    [0159] Likewise, an unlocking position is adopted when the user has actuated the actuator T. By means of the mechanical or traction cable C the force is transmitted and it is forced at one end or second portion L2 of the semi-free element, that is to say of the locking element L , to move upwards, so that it is not retained by the walls P1, P2, allowing a movement in X of the whole assembly.
