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.
