Modular door system for motor vehicle bodies incorporates buffer unit between inner and outer door panels to absorb initial shock during side impact

摘要

The door (10) consists of an inner panel (12) and an outer panel, and an integrated buffer unit (17). One side of the buffer unit is fastened to the inner surface of the outer body on the same level as the upper body of a passenger, the other buffer unit side projects towards the inner panel. The buffer unit consists of a main part, a curved side wall part extending from an edge of the main part to form a hollow space, and a flange. The flange extends towards the side wall unit, and is in direct contact with the inner face of the outer panel. The side wall unit has apertures.
