Abstract: A method for manufacturing decorative features in situ in a base layer of cast plastic material includes the steps of providing a heated mold tool with a selectively heated surface in the form of a desired decorative feature; depositing a covering of thermoplastic material in the recessed surface and heating the recessed surface to partially fuse the thermoplastic material on the recessed surface to form segments of plastic corresponding to the desired decorative feature; dumping excess thermoplastic material from the heated mold tool; thereafter spray coating the mold at the recessed surface to stabilize the location of the partially fused material in the recessed surface; reheating the mold tool to partially remelt the retained stabilized segments and thereafter depositing a base layer of thermoplastic material across the full surface of the mold and reheating the mold to bond the retained stabilized segments to the base layer and cooling and stripping the mold to form a finished plastic shell having a decorative feature formed in situ therein.

Abstract: An air bag door construction for air bag deployment comprises a trim panel and air bag door of unitary construction, at least a portion of the door defined by an area of reduced cross-section outlining at least a portion of the periphery thereof. One or more tethers are formed in the panel, outlined by an area of reduced cross-section, preferably in a dovetail shape which does not direct the propagation of tearing into the tether. A tear stop may be formed at the ends of the tether. The improvement comprises a stiffening frame that is attached to the backside and/or the topside of the panel just outboard of the air bag door periphery but not located across the tethers to improve deployment performance.

Abstract: An instrument panel of an automotive vehicle includes a rigid retainer preformed with an air bag opening and a recessed ledge extending about the opening. A separately formed door is installed on the opening and hinged to the retainer along one edge. The remaining three edges overlie the ledge to prevent inward movement of the door. The retainer and door are placed in a cavity of a mold tool in spaced relation to an outer skin and foam constituents are reacted therebetween to develop a foam layer. A foam seal is provided at the interface of the ledge and door to prevent the escape of foam past the ledge.

Abstract: An apparatus for deploying an air bag through an automotive dash panel includes an air bag door integrally formed in the panel and defined by a frangible edge of reduced cross section. A dispenser supports the air bag behind the door. A metal reaction plate is positioned between the air bag and the door. When the air bag inflates it forces the reaction plate to bend around a horizontal hinge line. As the reaction plate rotates it concentrates inflation force along a lower portion of the frangible door edge. This helps predictably separate the door from the dash panel by tearing along the lower door edge and allowing the tear to propagate up two side edges. In one embodiment, the tear also propagates across an upper edge to completely separate the door from the panel. At least one, and preferably two or three tethers limit how far the door can travel during air bag inflation. A stop member may be included to limit reaction plate bending. After deployment, the reaction plate remains in a position that prevents the door from returning to its original position.

Abstract: A cover assembly for concealing an automotive vehicle air bag restraint assembly with an air bag, an air bag housing and a gas generator located in the housing for supplying gas to the air bag in response to vehicle impact. The cover assembly includes an inner retainer panel secured between the air bag and a vehicle passenger compartment. An air bag door is mounted within an opening in the retainer panel. 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: An interior trim panel for a motor vehicle has an opening for deployment of an air bag and a discrete air bag door that is attached to the interior trim panel for closing the opening and for being opened by an air bag when it is deployed. The door includes a retainer that hinges the door to the trim panel and a covering that includes a frangible flap at an end of the retainer that holds down an end of the door and breaks away when the air bag is deployed. An alternate interior trim panel has another discrete air bag door that includes a bracket attached to the retainer for establishing the location of the hinge line. Another alternate interior trim panel arrangement has an integrated or invisible air bag door that includes a bracket attached to the retainer for establishing the location of the hinge line in an invisible door arrangement.
