    Abstract: A method of forming a motor vehicle instrument panel with a flexibly tethered air bag deployment door includes the steps of molding an instrument panel with a first plastics material to a desired shape and with an integral air bag deployment door whose opening is defined by a tear seam formed by a groove molded in one side of the panel and with an integral mounting/hinge flange that extends from an inside surface of the door, and forming a bonded layer of second plastics material on one side of the flange and the inside surface of a potentially frangible portion of the door. The second plastics material has the physical characteristic of remaining ductile to a substantial degree at low temperatures substantial below the temperature at which the first plastics material becomes brittle and as a result the bonded layer forms a tether that connects the frangible door portion to the mounting/hinge flange in a flexible manner when this door portion breaks away from the flange because of embrittlement of the first plastics material at the low temperatures on tearing of the tear seam and opening movement of the door by an inflating air bag pressing against the inside surface of the frangible door portion.

    Abstract: A discrete air bag tear seam is provided in the finishing cover of an interior component of an automotive vehicle. An applique installed on the cover has an elongated external decorator head concealing the tear seam. Elongated and laterally spaced retention flanges of the applique stabilize and releasably retain the cover at the tear seam. The applique is secured to a fixed retainer part of the component and operates by releasing the cover at the tear seam to form an air bag door in response to the forced outward movement of an underlying door substrate on air bag deployment. The underlying door substrate exerts a force on the cover and particularly the outer skin thereof and causes it to pull away from the applique starting at the concealed tear seam to establish an opening for improved air bag deployment.

    Abstract: A method for molding a thin walled plastic shell utilizes the following apparatus. An apparatus (40) for molding a thin walled plastic shell includes a mold box (42) having an inner mold surface (48). A powder box (52) includes an internal chamber and first divider wall (54) for separating the internal chamber into at least two sections (56,58). A carrier framework (60) is removably mounted on the mold box (42) and includes a peripheral seal for perfecting a seal between the mold box (42) and the powder box (52) when the same are connected thereto. A second divider wall (64) is connectable to the first divider wall (54) separating the inner mold surface into two chambers continuous with the two sections of the powder box (52). The carrier framework (60) further includes a mold surface seal (66) for perfecting a seal between the second divider wall (64) and mold surface (48).

    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.
