Abstract: A method for deployably concealing an air bag behind an instrument panel which includes a decorative plastic skin that covers a structural panel and a door that covers an opening in the panel. The panel includes a retainer and an outer foam layer adhered to a retainer outer surface. The door pivots on a hinge at a rear margin of the door. The skin is adhered to outer surfaces of the door and the panel. When closed, the door outer surface lies flush with the panel outer surface forming a seam between the door and the panel. The skin extends across the seam to conceal the door and panel. When opened, a front edge of the door pivots away from the opening to provide an air bag deployment path through the panel. A portion of the skin surrounding the door separates from the outer foam layer of the panel. The skin peels back to form a skin "tent" when the door opens. A delaminated front edge of the skin forms a tent opening that serves as an exit for the deploying air bag.
