Frame-shaped, unilaterally closed with a band-shaped cover support member of a motor vehicle

摘要

The invention relates to a frame-shaped supporting element of a motor vehicle for supporting a bumper containing an energy-absorbing material, more particularly a U-shaped profile (1) tied to the frame side rails (3) of the vehicle with the longitudinal edges of the U-shaped profile and the stiffening webs (4) possibly provided in the U-shaped profile as frame parts, whose free area enclosed by the frame faces the bumper and which is firmly closed by a web-shaped cover (2) facing the absorbing material of the bumper on the frame edges adjacent to the adjacent bumper. The aim of the invention is to increase the resistance of the web-shaped cover (2) against plastic deformation in case of a crash without having to increase the weight of said cover (2). According to the invention, said beam is characterized in that the web-shaped cover (2) has a concave configuration at least between some individual frame edges opposite the adjacent bumper in the entire free space of the frame that lies between said frame edges.
