The present invention relates to an arrangement for attaching the seat and more specifically to an arrangement for attaching a seat with respect to a vehicle bodyshell structural element, in which at least one locking means is able to attach said seat and is secured to a support element, this support element being held in position with respect to the bodyshell structural element.
It is known practice, when attaching seats, to use locking systems welded to elements secured to the vehicle bodyshell.
In the conventional way, and as depicted in
One of the objectives of the invention is therefore to propose an arrangement for attaching the seat which provides a reliable attachment of the seat, capable of withstanding load but which, in response to objectives invariably encountered with the various motor manufacturers, is inexpensive and not very bulky.
In order to meet these objectives, the invention proposes an arrangement as described hereinabove, and characterized in that the support element, the vehicle floorpan and the structural element are secured together by a common weld.
According to various features of the present invention:
The invention is also aimed at a motor vehicle, which comprises two independent seats attached with an arrangement as described above, and which comprises three support elements, one of these being a central support element comprising two locking means.
Other features and advantages of the invention will become apparent from reading the detailed description which follows, for an understanding of which reference will be made to the attached drawings in which:
In the description which will follow, a longitudinal, vertical and transverse orientation according to the traditional orientation used in motor vehicles and indicated by the trihedron L, V, T in
The present invention is aimed at protecting an arrangement for attaching a motor vehicle seat 1. In the exemplary embodiment which will follow, the attachment arrangement is described in relation to a rear seat 1 independent of a second rear seat. It will be appreciated that this arrangement can be applied to any vehicle seat, particularly a front seat, or to a rear bench seat, and that an attachment arrangement according to the invention may be combined with other means of attachment for the other attachment points of this same seat.
As depicted in
According to the present invention, the locking means 10 are welded to a support element 12, 13. As depicted in
According to the present invention, each locking means 10 is in the form of a cylindrical element, equipped at its center with a bore 11 able to collaborate with the locking systems associated with the seat 1 and which have not been depicted. Each cylindrical element rests against the underside 18 of a support element 12, 13 and is positioned in such a way that the bore 11 of the cylindrical element that forms the locking means 10 corresponds with an orifice 15 created in the support element 12, 13 so that the locking system associated with the seat can be inserted into this bore 11 through a downward vertical action.
The dimensions of each orifice 15 in the support elements 12, 13 are designed so that, on the one hand, the bore 11 of the locking means 10 is completely uncovered and accessible and, on the other hand, welded seams 20 can be created where the underside 18 of the support element 12, 13 makes contact with the periphery of the cylindrical element that forms the locking means 10. According to one embodiment of the invention, three arc welded seams 20 are created to secure the cylindrical element that forms the locking means 10 to the support element 12, 13. These three welded seams 20 are then arranged uniformly about the periphery of the cylindrical element, 120° apart. By way of example, these welded seams may be SMAW seams produced by gas-shielded metal arc welding.
The longitudinal dimension of each support element 12, is at least equal to the longitudinal dimension of the corresponding structural element 2 so that the edges 16 corresponding to the longitudinal ends of each support element can rest on and be attached to rebates 3 of the corresponding structural element 2.
According to the invention, each support element 12, 13 is formed of a plate with substantially flat edges 16 and at least one central part formed by a pressing 14 so that this central part is situated in a plane that lies lower than the plane containing the edges 16 of the plate and therefore of the rebates 3 of the corresponding structural element 2. As depicted in
According to one embodiment of the invention which has been depicted in
Each support element 12, 13 is welded to the floorpan 4 and to the corresponding structural element 2 by spot welds 22 capable of welding three thicknesses. As depicted in
The magnitude of the support elements 12, 13 in the transverse direction allows enough three-thickness spot welds 22 to be welded that the assembly is able to withstand the various loading scenarios.
Each spot weld 22 is therefore produced in order to weld together three thicknesses: the corresponding structural element 2, the vehicle floorpan 4, and the plate 12, 13 bearing the locking system 10. In the example depicted in the figures, the corresponding structural element 2 is the rear central crossmember and the floorpan is cut to allow the support plate and the locking means through.
The invention is not in any way restricted to the embodiment described and illustrated which has been given merely by way of example.
