COLLISION ENERGY ABSORBING STRUCTURE OF VEHICLE BODY UPPER PORTION OF AUTOMOBILE |
摘要 |
A collision energy absorbing structure of a vehicle body upper portion of an automobile having a roofside rail (20) extending in the forward and backward direction and formed to be a closed structure with an outer panel (30) and an inner panel (32) includes a metal energy absorbing panel (22) and a resin interior trim material (24). The energy absorbing panel (22) has a thickness smaller than the thicknesses of the outer panel (30) and the inner panel (32) and is arranged with a space (D) inward of the inner panel. The terminal portion in the longitudinal direction of the energy absorbing panel (22) has a tendency that energy absorption reduces but the tendency is compensated by resin material (26, 28).
