ABSTRACT:
A bearer, especially a longitudinal bearer of a motor vehicle frame, which is constructed as hollow profile and includes a deformable section dissipating impact energy; the walls of the longitudinal bearer have different strength characteristics as a result of a treatment of these areas changing the strength of the wall material compared to non-treated areas; a greater strength thereby exists in the treated wall areas than in the untreated areas.
