Definitions
- the invention relates primarily to a frame of seat backs of the rear row of a motor vehicle.
- the invention also relates to a motor vehicle equipped with at least one such frame,
- Backrest seats of the three-seater rear row seats of a motor vehicle generally consist of a first frame corresponding to a lateral seat back, and a second frame of greater width corresponding to the opposite side seat back and backrest central seat.
- the first and second frames can be independently folded to give the rear seat row the name of seat 2/3 - 1/3 illustrating the ability to fold 1/3 or 2/3 of the row of rear seats to increase the volume of loading the vehicle.
- These frames are specifically sized according to the vehicle in which they are mounted. Therefore, it is not possible to use these frames, and in particular the second frame covering the lateral seat back and the central seat back, for vehicles with different widths of rear seat rank.
- these frames have a significant weight.
- the reduction of carbon dioxide emissions includes reducing the weight of vehicles.
- the publication WO2013001 19 describes a seat back frame 1 comprising a first support element 2 forming the bottom of the back of a side seat and consisting mainly of a rigid tubular frame 3 on which an element extension support 4 made of a folding steel wire 5 forming the bottom of the central seat back is secured.
- the armature also comprises a second support element 6 identical or symmetrical to the first support element 2 and forming the bottom of the back of the opposite side seat.
- the extension support member 4 may provide a head support frame 7 welded on its upper part and intended to receive the lining of the head support.
- the invention relates to a frame of seat backs of the rear row of a motor vehicle to overcome the aforementioned drawback.
- the backrest frame of the rear row of a motor vehicle of the invention is essentially characterized in that it comprises a main support member forming the frame of a lateral seat back, and an extension support member forming a backrest of the central seat which is secured to the main support member extending in the same plane, and which comprises a receiving member of two headrest guides.
- the armature of the invention may also include the following optional features considered in isolation or in any possible technical combination:
- the receiving element of the two sliding headrest guides consists of two hollow metal tubes welded to the extension support element and in which two parallel headrest guides are intended to be mounted.
- the extension support member comprises a sheet which extends over the entire height of the main support member, and the hollow metal tubes are welded to said sheet.
- the hollow metal tubes are welded to a metal cross member which is itself secured to the extension support member.
- the extension support member comprises a folded steel tube which extends over the entire height of the main support member, and the metal cross member extends from the upper end of the folded steel tube to the main support element.
- the receiving element of the two sliding head support guides is a hollow body which is integral with the extension support member and on which is provided a snap interface of the two headrest guides traversing the said hollow body.
- the extension support element comprises a folded steel tube which extends over the entire height of the main support element, and in that the hollow body forming a receiving element of the two sliding support guides head is a hollow cross member extending from the upper end of the folded steel tube to said main support member.
- the extension support element comprises a stamped sheet which extends over the entire height of the main support element, and the hollow body forming a receiving element of the two sliding headrest guides is a hollow cross-member; secured to the upper part of said sheet.
- the armature comprises a second lateral support member forming the frame of an opposite lateral seat back, the first and second lateral support elements being identical or symmetrical relative to a transverse center axis of said armature.
- the invention finally relates to a motor vehicle equipped with at least one armature as previously stated.
- FIG. 1 is a schematic representation of the front face of a rear seat seat backrest reinforcement of the prior art
- FIG. 2 is a schematic representation of the front face of a seat back frame of the rear row of a motor vehicle according to a first variant of the invention
- FIG. 3 is a schematic representation of the front face of a seat back frame of the rear row of a motor vehicle according to a second variant of the invention.
- FIG. 4 is an enlarged schematic representation of the cross member of the extension support member on which are mounted the headrest guides according to a third embodiment of the invention.
- the rear seat back frame of the invention 10,10a comprises a first main support member January 1 and a second main support member 12 corresponding to the respective frame left and right side seat backs.
- the first 1 1 and second 12 main support elements are identical or, when they are asymmetrical with respect to their own transverse median axis XX ', they have a symmetry with respect to the transverse median axis YY' of the armature of the invention 10,10a ( Figure 2).
- Each main support element January 1, 12 comprises a rigid tubular frame 13,14 with a cross sectional diameter of 25 millimeters and a metal thickness of 1.5 millimeters. It goes without saying that these specific dimensions are adapted by those skilled in the art.
- the rigid tubular frame 13,14 of each of the main support elements 11, 12 is of substantially rectangular shape and comprises an upper segment 15,16, a lower segment 17,18, a lateral end segment 19,20 and a central lateral segment 21, 22.
- each lateral support element 2, 3 comprises latch hinges 23,24, a latch support 25,26 and a hinge axis 27,28.
- an extension support member 30 forming the frame of the central seat back is secured to a main support member January 1 extending in the same plane.
- the extension support member 30 comprises a folded steel tube 30a extending over the entire height of the main support member.
- the lower portion of the extension support member 30 is U-shaped 34, the lateral branch 35 of the side of the main support member January 1 is welded to the central lateral segment 21 of this main support member January 1 .
- the upper end 31 of the extension support member 30 is secured to a metal cross member 32 extending from the upper portion of the central lateral segment 21 of the main support member January 1.
- the opposite ends of the metal cross member 32 are respectively welded to the upper end 31 of the extension support member 30 and to the upper part of the central lateral segment 21 of the main support member January 1.
- two hollow metal tubes 33 are welded vertically on the crosspiece 32. These two metal tubes 33 form a receiving element of two plastic head support guides not shown. In known manner, these two plastic guides form two parallel metal rods slidable in these plastic guides and integral with the headrest of the seat back considered.
- a non-visible snap-in interface is provided inside each hollow metal tube 33 in order to join the plastic head support guides.
- the crossmember 35 can be hollow in order to directly provide two latching interfaces 36 of the two plastic head support guides 37.
- the extension support member 38 is a stamped sheet whose peripheral edges are rolled to position and maintain the lining of the central seat back.
- the stamped sheet 38 extends over the entire height of the support element, its lateral edge 39a on the side of the main support element January 1 being welded to the central lateral segment 21 of the main support element January 1;
- two hollow metal tubes 39 are welded vertically and in parallel. As for the variant already described in Figure 2, these two hollow metal tubes 39 form receiving element of two plastic head support guides not shown.
- the central support element 30,38 of a seat back frame of the rear row of a vehicle can be equipped with a receiving element of the plastic head support guides for mounting height-adjustable headrests.
