Abstract: An underbody structure for at least two motor vehicles, in particular for at least two passenger cars having a first and a second wheelbase, is provided. The underbody structure comprises a middle underbody structure and a rear underbody structure with laterally arranged side members, between which at least one connecting profile is arranged. The connecting profile is connected to the side members and to a floor of the middle underbody structure to form a first overlap region for the first wheelbase and a second overlap region for the second wheelbase. The first and the second overlap region have an at least approximately same width.

Abstract: With a motor vehicle having a front axle and rear axle, underbody and shock absorbers, each of which extend between an upper point of action on the underbody and a control arm on the rear axle extending adjacent to a rear wheel, and at least one back seat the upper point of action of one of the shock absorbers is located vertically below the back seat.

Abstract: A vehicle chassis structure includes, but is not limited to a central tunnel extending in the longitudinal direction of the vehicle, plate sections extending on both sides of the central tunnel, and two longitudinal beams projecting over a front edge of the plate sections, which are constructed respectively in one piece with two branches, an inner branch of which extends on one of the plate sections to the central tunnel, and an outer branch is connected with an outer sill, which extends on an edge, facing away from the central tunnel, of one of the plate sections.

Abstract: A seat attachment device in a motor vehicle with a first row of seats and a second row of seats is provided. The seat attachment device includes at least two longitudinal rails adjacent to each other in the traveling direction, which are suitable for establishing a connection with a vehicle floor on their lower side and accommodating at least one seat element of the second row of seats on their upper side. The longitudinal rails each exhibit a recess suitable for accommodating a cross member lying transverse to the traveling direction. Also provided is a method for installing a second row of seats.

Abstract: An energy storage arrangement is provided in a floor area of a vehicle that includes, but is not limited to an energy storage device carrier having a floor and side walls with a fixing mechanism for fixing at least one energy storage device. An underfloor mounting plate fixes the energy storage device carrier and the energy storage device provided in said energy storage device carrier on an underfloor structure of the vehicle. A cover plate in the floor area of the vehicle covers at least the energy storage device carrier toward the vehicle interior in a media-tight manner.

Abstract: A frame structure is provided for the underbody of a self-supporting motor vehicle bodywork. The frame structure includes, but not included with an elongate tunnel and two sillboards parallel hereto. The sillboards are disposed on both sides of the tunnel. The frame structure also includes, but is not limited to a dashboard cowl with closing plate, which is connected directly to both sillboards and the tunnel, a wheel housing with a downwardly open main structural arc, the ends whereof are connected to the underbody, and on its side facing the underbody (e.g., the vehicle inner side) the main structural arc has a damper receptacle in its upper area, from which a supporting strut connected to the underbody projects downward.

Abstract: A motor vehicle front end and a method for producing a motor vehicle front end are provided in accordance with embodiments of the invention. The motor vehicle front end has a front wall and the front wall girder, the front wall girder essentially being situated in the direction of a vehicle transverse axis. In addition, the motor vehicle front end has a first front wall girder, the first front wall girder being situated essentially in the direction of a vehicle vertical axis. The first front wall girder is supported on the front wall crossbeam in a first area of the front wall crossbeam.
