Description

Title of the invention: Seat and seating assembly for vehicle and associated vehicle Technical field of the invention

[0001] The present invention relates to a seat and a set of seats or a bench seat for a vehicle, as well as a vehicle comprising such a seat. In particular, the invention relates to a rear seat or a rear bench seat for a vehicle.

[0002] Prior art Safety standards mandate that the seat belt cannot be severed in its nominal position and in the event of a collision, particularly a side or frontal impact. To this end, the edges of vehicle floor panels are generally oriented in the opposite direction to the seat belt. However, for some rear seats with a narrow, pivoting central backrest, this positioning can lead to the upholstery and trim at the corners of the central backrest being torn away due to friction when the central backrest is tilted forward, for example, when transporting long loads. This tearing of the seat upholstery and trim is visible and unsightly. Presentation of the invention

[0003] A first object of the present invention is to prevent the severing of the seat belt strap in nominal position and in case of impact. A second objective of the present invention is to allow the tilting of the rear seat center backrest without tearing the upholstery and trim of the corner of the backrest while respecting the safety standards prohibiting the possibility of cutting the seat belt strap.

[0020] In this description the term reference seat 2 means front seat, rear seat, set of seats or rear bench seat of a vehicle. An orthogonal XYZ coordinate system is defined with respect to the vehicle. It comprises three axes perpendicular to each other: an X axis defining a longitudinal direction coinciding with the general direction of movement of the vehicle, a Y axis defining a transverse direction and a Z axis defining a vertical direction. In the following description, and in relation to the reference frame defined above, the terms "longitudinal" or "longitudinally" refer to a direction coinciding with the X-axis, the terms "transverse" or "transversely" refer to a direction coinciding with the Y-axis, and the terms "vertical" or "vertically" refer to a direction coinciding with the Z-axis. Absolute position terms, such as "front", "rear", "up", "down", "left", "right", or relative terms such as "above", "superior", "below", "inferior" are defined with respect to the normal direction of travel of the vehicle corresponding to "forward movement". Identical or similar technical elements are designated by the same references.

[0021] With reference to [Fig. 1], an example of a vehicle seat 2 according to the invention comprises a support structure 4 extending along the transverse direction Y, a first 6, a second 8 and a third 10 backrest frames mounted pi- voters in relation to the support structure. Support structure 4 is, for example, a metal bar. The first, second, and third backrest frames consist of a metal structure designed to serve as the framework for a seat back. The first backrest frame 6 is adjacent to the second and third backrest frames. It is generally positioned in the center of the support structure 4. The second and third backrest frames are similar to the first backrest frame. In the embodiment shown schematically in [Fig. 1], the first backrest frame 6 has a width less than the width of the second and third backrest frames. It also includes a stiffening plate 12 covered with padding and upholstery, for example, fabric. This stiffening plate advantageously helps maintain the shape of the backrest during the installation of the upholstery. Indeed, given the narrow width of the first backrest frame, it deforms during upholstery installation due to tension. Advantageously, this stiffening plate increases the comfort of the passenger leaning against the first backrest frame 6. Seat 2 comprises a first 14 and a second 16 central floor slabs fixed to the support structure 4 and two lateral floor slabs 18, 20 also fixed to the support structure 4.

[0022] The first floor slab 14 is made of stamped sheet metal. It comprises a base 22 intended to be fixed to the floor 23 of the vehicle and a fin 24 extending substantially perpendicular to the base.

[0023] The fin 24 is substantially flat to allow the backrest frames to pivot. It comprises a front portion 25 and a rear portion 27. The rear portion extends longitudinally in the vertical direction Z. The first 6 and second 8 backrest frames are pivotally mounted on the rear portion 27 of the fin. A portion of the rear portion of the fin 24 is located between the first and second backrest frames. The fin has two main faces 31, 32, a front longitudinal edge 26 directed towards the front of the vehicle and towards a seat not shown in the figure and a rear longitudinal edge 28 directed towards the rear of the vehicle. In the embodiment shown in [Fig.2], the front longitudinal edge 26 is a dropped edge 29 directed towards the second seat frame. It extends along the front part 25 and the rear part 27 of the fin. In the embodiment shown, a portion 30 of the front longitudinal edge 26 the fin has a rounded shape with a center of curvature located outside the fin. In the illustrated embodiment, the fin 24 has a hole 56 and a through-hole 58 arranged at a distance from each other on the front part 25 of the fin. These through-holes are intended for the attachment of a protective cover illustrated in [Fig. 3]. With reference to figures 1 and 2, seat 2 further comprises a first element 33 of a safety belt fixed to the first floor slab 14 and a second element 34 of a safety belt fixed to the second floor slab 16. The first element 33 of the seat belt comprises a first fastening member 36 of the clasp type, a flexible strap 38 attached to the fastening member and an anchor plate 40 for the flexible strap attached to the base 22 of the first floor slab. The flexible strap 34 extends opposite the main face 31 of the flange when the seat belt is in a nominal operating position as illustrated in [Fig. 2]. As seen in Figures 1 and 2, the longitudinal edge 26 of the fin, i.e. the edge that falls in the embodiment shown, is directed towards the flexible strap 34, when the safety belt is in a nominal operating position. Advantageously, the seat includes a protective cover 46 arranged on a portion of the longitudinal edge of the fin and covering this portion.

[0024] Advantageously, the protective cover prevents the flexible strap of the safety belt from being cut, in the nominal operating position when it extends parallel to the fin and in the event of a side impact when it tilts in the direction indicated by arrow F. Preferably, the protective cover 46 comprises a bottom wall 48 and two side walls 50, 52 perpendicular to the bottom wall. Advantageously, the edges between the side walls and the bottom wall are rounded.

[0025] The bottom wall 48 rests on a face of the longitudinal edge 26 of the fin. This face of the longitudinal edge of the fin is formed by the upper face of the inclined wall of the dropped edge. When the edge of the fin is a straight edge, this face of the edge of the fin is formed by the edge of the fin.

[0026] The side walls 50, 52 extend parallel to the fin and are fixed to the fin. Advantageously, the shape of the protective cover allows for a durable fixing of the protective cover to the first floor slab 14.

[0027] In the illustrated embodiment, the protective cover 46 further comprises an end wall 54. Alternatively, the protective cover 46 does not comprise an end wall 54.

[0028] In the embodiment shown, the side walls of the protective cover each include at the front a clip 60 engaged in the hole 56 of the fin, and at the rear an orifice 62. The protective cover 46 further includes a fastening element 64 of the screw, bolt nut or rivet type arranged in the through orifice 58 of the fin and in the orifices 62 of the side walls of the protective cover to fix the protective cover 46 to the first floor slab. Advantageously, the absence of the fastening element 64 can be easily detected on the assembly line. Alternatively, the protective cover can be secured with two clips or two fasteners. Specifically, the protective cover can be secured with two clips and two screws. The protective cover 46 can be made of plastic, preferably polypropylene or polyethylene. With reference to figures 1 and 4, the second element 34 of the safety belt comprises a second attachment member 42 of the penne type, a flexible strap 44 attached to the attachment member and an anchor plate 40 of the flexible strap attached to the base 22 of the second floor slab. The longitudinal edge 26 of the fin of the second floor slab 16, i.e. the dropped edge, is directed towards the flexible strap 44, when the safety belt is in a nominal operating position. Advantageously, seat 2 also includes a protective cover 46 covering at least a portion of the longitudinal edge 26 of the fin of the second floor slab 16. The protective cover prevents the flexible strap from being cut when it comes into contact with this longitudinal edge. According to an alternative not shown, the portion of the longitudinal edge of the fin has a substantially horizontal part and a substantially vertical part. In this case, the bottom wall 48 of the protective cover comprises two walls extending perpendicularly to each other. According to an unshown variant, the front longitudinal edge 26 is straight. It does not have a dropped edge.

[0029] In this case, the bottom wall 48 of the protective cover is in contact with the edge of the fin.

[0030] According to a more environmentally friendly variant, the protective cover is made of metal or wood.

[0031] Alternatively, the seat or seat assembly does not include a support structure 4. In this case, the first backrest frame 6 is connected to the first floor slab 14. This connection is a pivot connection. Thus, the first backrest frame is mounted pivotally relative to the first floor slab.

[0032] The second backrest reinforcement 8 is also connected to the first floor slab 14. This connection is a pivot connection. Thus, the second backrest reinforcement is mounted pivotally relative to the first floor screed.

[0033] Finally, the third backrest reinforcement 10 is linked to the second floor slab 16. This connection is a pivot connection. Thus, the third backrest frame is mounted pivotally relative to the second floor slab.

[0034] According to one embodiment, the seat belt anchor plate 40 is directly fixed to the floor 23 of the vehicle. Advantageously, the cover protects the flexible seat belt webbing both when it is in its nominal position and in the event of a frontal or side impact. The flexible webbing will rub against the protective cover. Thanks to the rounded edges of the cover, it will not be severed by the protective cover.
