Abstract
Abstract An apparatus for use in an air bag safety restraint system including: a deployment door (20) having a first part (36, 38, 39) including a tear seam (38) along one side thereof, attached to a cooperating structure (22) to permit the door to open when the tear seam is stressed, a central portion (32) connected to the first part via the tear seam and an integral hinge (42) connected to the central portion (32) and integral therewith. A door retainer bracket (70) is provided with a plurality of lands (72a-72b) and a plurality of rectangular shaped bosses (74a-74c) each boss having a fastener hole (78) therein. The door retainer bracket is fitted to a flange 44 of the cover 20 such that the lands lie against flat portions of the flange (44) and the bosses extend into corresponding rectangular openings 60a-60c of the flange. A door retainer plate (90) is mated against an outward side (80) of the flange 44 and includes fastener openings (94) aligned to the fastener openings (78) in the door retainer bracket (70).
