A hinge connects the door to the retainer panel and allows the door to swing open under the force of an inflating air bag. A foam layer is sandwiched between an outer skin and the retainer panel and extends across both the retainer panel and the air bag door. A weakened tear-seam is formed in an outer surface of the outer skin and runs parallel to and adjacent an edge of the door opposite the hinge. A rigid applique is supported in a layered disposition over the outer skin to conceal the weakened tear-seam from passenger compartment occupants.

Abstract: A molded motor vehicle instrument panel made of a thermoplastic material has an integral air bag deployment door for a passenger side air bag that is defined by a tear seam and is normally retained by an integral flexible mounting/hinge flange to a part of the vehicle structure when the seam is torn by the inflating air bag and wherein this flange then bends to allow the door to swing open to allow deployment of the air bag through an opening in the instrument panel while retaining same to the vehicle structure as the door is then free of the instrument panel. At very low temperatures, a portion of the air bag door can break away from the mounting/hinge flange because of plastic embrittlement at these low temperatures and the high bending stresses encountered at this juncture.

Abstract: An arm rest (18, 20, 22) is mounted for vertical adjustment relative to the door panel (14) or center console (16). The arm rest is operably connected to an air spring bladder (32, 46, 54) or an adjustable mechanical mechanism (72). The bladder is controlled by a pump (40) and switch (41). The mechanism (72) is controlled by an electric motor (70).
