Abstract

Abstract A method and arrangement is disclosed for providing one or more air bag deployment doors in which an explosive containing coating is deposited on the inside of an auto interior trim piece in the pattern of the doors immediately over the air bag receptacle in which the air bag is stored. The coating is comprised of a suspension of explosive material in a carrier which is detonated when the system is activated and the door or doors so formed are pushed open by the inflating air bag.
