Crashbox for motor vehicles

The crash box is fabricated from a semi-finished sheet metal part (1), which is bent and/or folded into a multiple chamber profile, esp. a double chamber profile. Open sides and/or butt-jointed segments of the profile are closed esp. by welding, riveting, jointing and/or adhesive. Before forming, the profile is subjected to at least one further forming process, e.g. punching, folding and/or raising. The crash box contains deformation elements (10,12,13,16,17), which are mainly located on the outside, and it also has apertures (18-21), cut-outs, stiffeners, brackets (28,29), etc.
