Abstract

The tubular reinforcement member (2) has a circular cross section. Compared to the end portions serving for fastening the reinforcement member to the inner side of the door, the middle portion (1) in longitudinal direction of the reinforcement member has a greater resistance against bending loads. For this purpose, at least one sheet steel strip (4) extending parallel to the longitudinal axis (3) of the reinforcement member is tangentially fastened to the periphery of the middle portion (1) in a plane extending parallel to the impact direction (5). The width (B) of the sheet steel strip (4) is overall smaller than the thickness (D) of the reinforcement member. The width (B) decreases in accordance with the bending moment pattern toward the ends of the sheet steel strip (4). The decrease in width may be linear or parabolical.
