The vehicle energy absorbing beam comprises a long rectangular section caisson (1) formed from two U shaped sections (10,11) which are fitted and welded together. The caisson has on two opposite sides a succession of convex portions (20) separated by plane portions (21). On the other two opposite sides are a succession of concave (22) portions separated by plane portions (23). The length and depth of the convex and concave portions is variable, according to their placing on the caisson, as a function of the deformations to be obtained. |
