Abstract: Vehicle bodies having a mounting frame fastened to a floor frame lead to damage to the mounted assemblies and floor frame when, for example, the engine assembly is arranged directly adjacent to the vehicle front or rear side. It is proposed to provide a crossmember of the mounting frame as a member for the bumper and to provide in the side members, in the region of the other crossmember, deformation zones which, in the event of a collision at relatively low speed, allow a displacement of the entire mounting frame together with the built-in assemblies, without the floor frame being damaged. The mounting frame is usable for vehicles with a rear or front engine.
