Abstract
In an automotive door assembly including an outer panel and an inner panel, the inner panel is reinforced by a plate member attached to the outer surface of the inner panel so as to define a closed vertical cross section by a pair of mutually opposing concave surfaces thereof. The inner reinforcement member is relatively large in thickness but is allowed to relatively readily extend vertically by being relatively sharply bent at upper and lower portions thereof. Thus, according to the present invention, the automotive door demonstrates a relatively high rigidity against external side impacts, and can spread the impact energy over a large area, thereby involving a relatively small deformation. On the other hand, the door can readily deform itself against internal side impacts, and a relative large amount of impact energy can be absorbed again without involving a large lateral deformation because the collapsing and the vertical extension of the closed cross section formed by the inner panel and the associated inner reinforcement member allows a large amount of energy to be absorbed.
