Abstract

The reinforcement member of a body structure is composed of two member elements which are of u-shaped profile in cross section and which are arranged nested one inside the other. Turned-up limb portions of the outer member element have edge-side retaining lugs between which are arranged edge-side cutouts. The retaining lugs can be connected to turned-up limb portions of the inner member element, and connecting points to the bodywork outer shell are arranged in the interposed cutouts. The outer member element is composed of a high-strength steel material, with the inner member element being composed of a relatively low-strength steel material, and the terminating bodywork outer shell is formed from an aluminium material.
