A motor vehicle bodywork has a floor assembly with an upwardly convex and downwardly open longitudinal center tunnel and two side sills parallel thereto. Floor elements are disposed between the longitudinal center tunnel and the side sills. A driver side and a passenger side are each provided with at least one front and one rear seat crossmember, seen in the direction of travel. The seat cross-members extend in the transverse direction of the vehicle and rest on the associated floor elements. It is important that the driver side and/or passenger side seat cross-members are each connected to each other in their upper regions via a plate-like thrust element.

Bodywork

A motor vehicle has a rear axle cross member, from which two diagonal struts project forward in a V-shape, which diagonal struts are connected with their front end in each case to a vehicle longitudinal member. Here, it is important that an annular, closed stiffening structure is provided behind the rear axle cross member as viewed in the direction of travel. The stiffening structure is supported with its front end on the rear axle cross member and with its rear end, via struts which project rearward in a V-shape, on rear vehicle longitudinal members.

Motor vehicle

A rollover protection device is disposed behind the vehicle seats of a motor vehicle, in particular a convertible with a convertible top, and has at least one rollover protection cassette containing a rollbar. It is important here that the at least one rollover protection cassette or a housing of the same is a supporting component of a stiffening support which is of multi-part construction and extends in the transverse direction of the vehicle.
