Abstract

A vehicle frame consisting of longitudinal bearers with hollow profile which are interconnected near their ends by at least one transversely extending element; at least one of the edges of the longitudinal bearers is provided with intentionally weakened places for reducing the compressive strength in the end areas, which are constructed as beads or corrugations that extend preferably in the vehicle transverse direction; the beads or corrugations may thereby have their greatest depth in the area of the edges and after reaching the bearer walls adjoining on both sides thereof, run out in the plane thereof.
