Device for impact energy absorption by plastic deformation according to principle of rolling bend, particularly crash-box for motor vehicle, has tubular intrusion section formed in conical tapered manner from averted end

摘要

Device has a tubular supporting section (1.1) and a tubular intrusion section (1.2). The intrusion section is formed in a conical tapered manner from an averted end, which is seen in a direction of a transient area. The conical taper ratio extends from the averted end of the intrusion section to the transient area.
