Abstract: A motor vehicle chassis includes two lateral floor supports and a seat-cushion support part positioned between two lateral raisers fixed on top of the lateral floor supports and assembled with the lateral floor supports. The chassis further includes two seat-cushion support reinforcements each assembled with a lateral floor support and with a lateral raiser, each seat-cushion support reinforcement including: a substantially horizontal plate extending the seat-cushion support part laterally, assembled with the lateral raiser along a substantially vertical mating edge of the plate, and a single support leg extending downwards from the plate, assembled with the lateral floor support, and the assembly end of which is positioned vertically below the plate, some distance from a projection onto the horizontal of the mating edge.

Abstract: A motor vehicle chassis including a rear central cross member, a hollow beam positioned over the rear central cross member along this rear central cross member, and a floor seat-cushion support part including rear seat fittings, supported at the rear by the hollow beam positioned under the seat-cushion support part. The beam includes a rear raiser including a horizontal plate fixed to the rear central cross member and further includes a blanking sheet fixed to the horizontal plate of the rear raiser and including at least one anchoring reinforcement assembled on the inside of the hollow beam. The reinforcement, which forms a hollow box section, connects the rear raiser and the blanking sheet, an upper face of the anchoring reinforcement supports a connecting piece, the connecting piece also being assembled, on the outside of the hollow beam, with the rear raiser.

Abstract: A motor vehicle chassis includes two side rail members covered at the front by two lateral floor reinforcements, a rear central cross member and a transverse reinforcement which is welded to the two lateral floor reinforcements, and a floor having a seat-cushion support part. The chassis further includes a rear raiser welded to the rear central cross member and two lateral raisers welded respectively to each of the two lateral floor reinforcements. The seat-cushion support part of the floor is welded to the two lateral raisers, to the rear raiser and to the transverse reinforcement, so as to create a space for an energy reservoir under the seat-cushion support part of the floor.

Abstract: A motor vehicle chassis including two side skirt lateral flanks comprising a horizontal portion. The motor vehicle chassis also includes a central floor situated between the two side skirt lateral flanks and including a horizontal main surface and horizontal secondary surfaces for attachment to the horizontal portion of the lateral flanks. The horizontal surfaces exhibit a height difference. The motor vehicle chassis also includes at least one fixing piece on each side of the central floor, between the horizontal main surface of the central floor and one of the side skirt lateral flanks. The at least one fixing piece includes two horizontal parts for fixing to the central floor, which are respectively fixed to the horizontal main surface and to a horizontal lateral surface of the central floor. One of the horizontal parts includes a first passage to accept a fixing lug of a bodywork element.
