an automotive instrument panel includes a molded plastic retainer formed with an integral airbag deployment door surrounded by a channel defining a tear seam enabling the door to separate and hinge outwardly upon deployment of the airbag . a foam - backed cover of flexible plastic material is applied over the outer surface of the panel and is severed along the length of the channel to eliminate any influence that the cover may have on resisting the opening of the door . the severed cover portion can either be removed to expose the door or else be left in tact and bonded to the door .
