Abstract: A chassis for a passenger car includes two main longitudinal chassis beams which are connected to one another via a bumper cross member. A support arrangement extends between the two beams and is supported on a central tunnel. The support arrangement forms a load path in an event of a collision-related force being applied to the passenger car where above and/or below the support arrangement an installation space region is provided for accommodating a component or unit in need of protection. The support arrangement includes a strut which extends in a region of a center of the passenger car between the two beams and which forms a protective device which transmits impact forces forwards to the central tunnel. The strut has a first longitudinal section that is deformable in a targeted energy-absorbing manner and a second longitudinal section which functions as a rigid beam.

Abstract: A motor vehicle column includes an inner shell and an outer shell made from a metal, which are connected to each other in respective flange regions and which enclose a hollow space between them. In the hollow space a reinforcement element having a basic body made from a fiber composite plastic is arranged to strengthen the body component. The reinforcement element includes a metallic insert, which connects the reinforcement element to the inner and/or outer shell.
