UNDERRIDE PROTECTION FOR A VEHICLE WITH METAL FOAM IN A HOLLOW PROFILE

摘要

The invention relates to an underrun protection (2) for a vehicle which is light and in the event of a collision absorbs as much energy as possible through deformation work without breaking. The invention also relates to a vehicle with such an underrun protection (2) and a method for producing an underrun protection (2) for a vehicle. This problem is solved by an underrun protection (2) in which a metal foam (8) is arranged in the hollow profile (4). The object is also achieved by using a hollow profile (4), in which a metal foam (8) is located, for an underrun protection (2) of a motor vehicle. By introducing the metal foam (8) into the hollow profile (4), the energy absorption by the underrun protection (2) is significantly increased in the event of a collision. At the same time, the deformability of the metal foam (8) ensures that the underrun protection (2) does not break even if it is severely deformed. The metal foam (8) is also characterized by its low weight, so that the total weight of a vehicle equipped with the underrun protection (2) according to the invention is only slightly increased.
