Abstract
Abstract Inner and outer reinforcing and shock absorbing members are mounted on the inner panel of a vehicle door. The inner member is designed to provide only low resistance to a lateral impact force caused by a lateral collision and the outer member is designed to provide high compression resistance in a fore-and-aft collision of a vehicle.
