Abstract The method for making an energy absorbing panel comprises the steps of coating a stretchable lightweight fabric with resin, molding the resin coated fabric into a generally planar sheet having a plurality of spaced apart conical projections rising from the planar sheet, cutting the fabric to provide molded panels in a size and shape of the desired energy absorbing panel structure, cutting adhesive coated planar sheet material in a size and shape of the desired energy absorbing panel structure to provide interface panels, interleaving the molded panels and the adhesive coated interface panels to the desired thickness of the energy absorbing panel structure, and then curing the adhesive to attach the panels and thereby form the energy absorbing structure. Upon the imposition of a force against the energy absorbing structures, the resin rigidified projections collapse to absorb energy. The energy absorbing structure is mounted on a vehicle door above the arm rest and below the window opening between the door trim panel and the door inner panel to absorb energy in the event that the occupant contacts the door inner panel.
An energy absorbing vehicle door comprising: inner and outer panels joined together in spaced apart relation and having upper marginal portions defining a window opening; an arm rest mounted on the inner panel in spaced relation beneath the window opening; a door trim panel mounted on the inside of the inner panel between the window opening and the arm rest and concealing the inner panel; and an energy absorbing structure interposed between the door trim panel and the inner panel beneath the window opening and above the arm rest and including a plurality of energy absorbing sheets of stretchable lightweight textile fabric having a generally planar base and a plurality of resin rigidified spaced apart conical shaped projections stretched from the base, and an interface sheet of generally planar material interleaved between the adjacent sheets of stretchable lightweight textile fabric and adhesively secured thereto to define an energy absorbing structure whereby the application of a predetermined load thereto causes the collapse of the resin rigidified stretched projections and absorbs energy.
