VEHICULAR METAL ABSORBER, VEHICULAR BUMPER SYSTEM, VEHICULAR BUMPER ABSORBER, AND AUTOMOBILE BUMPER SYSTEM

摘要

A vehicular metal absorber which efficiently absorbs the impact energy exerted from pedestrian legs at a short stroke and protects the pedestrian legs with less remaining crushed parts in the event of collision between pedestrian and automobile. The vehicular metal absorber comprises a center flange, a top web and a bottom web leading to both sides of the center flange, a top flange leading to the top web and a bottom flange leading to the bottom web as a lengthy absorber with its cross-sectional surface integrally formed in a hat shape. On the hat-shaped cross-sectional surface, the inner angle α1 formed between the top web and a flange surface including the top flange and bottom flange as well as the inner angle α2 formed between the bottom web and the above flange surface is above 0 (degree) and below 90 (degrees), and a concave or convex bead roughly parallel to the anteroposterior direction of a vehicle is provided at either one or both of the top web and bottom web.
