Bumper cross member for a vehicle

Bumper beam for a vehicle, especially a motor vehicle, which is fixed on the vehicle side at least two mutually spaced suspensions, with two connected sections (2, 3) which form a across the width of the vehicle extending hollow body (1) and at least one of the profiles (2, 3) is coupled to the suspensions, characterized in that the profiles (2, 3) in cross-section such convex and congruent to each other formed bulges and their elongated lengths at least approximately the same length, that formed at a force application to as a compression chord profile (2) is elastically deformed and the same applied forces transferred to serving as a tension chord profile (3), which is also elastically deforms until the two profiles (2, 3) bear against each other approximately.
