Abstract: A closure for an air bag assembly includes a flexible outer skin and a layer of foam material covering a retainer member that has an air bag deployment opening that is closed by a moveable door. The door overlaps portions of the retainer member to support the door against movement inwardly of the retainer member and allow free hinging movement outwardly of the retainer member for stressing and separating the layer of foam and the outer skin to form a deployment path for the air bag. The moveable door may be retained in the closed position by frangible portions of the retainer member to facilitate manufacture of the closure.
