Abstract

The deformation member (1) is disposed between a longitudinal member (2) and a cross member (3) of a motor vehicle, with the cross member having a horizontal central longitudinal plane which is vertically offset to the horizontal central longitudinal plane of the longitudinal member (2). The deformation member includes an elongate, hollow base body (4) of polygonal cross section and a height which is greater than its width, and an upper and a lower reinforcing shell (14, 19) which are connected through welding to the base body (4) via the longitudinal edges of their legs (13, 18). The end walls of the lower reinforcing shell (19) are closed by cover plates (22, 24). The deformation member (1) can be coupled via a plate (23) with the longitudinal member (2) of the motor vehicle.
