Abstract: A cover for covering an air bag in a motor vehicle has a thin elastic plastic skin, a rigid substrate and an intermediate layer of soft plastic foam. The skin has a tear seam and the substrate includes a door that is impacted by the inflating air bag and presses outward against the foam layer and the skin to tear the foam layer and the tear seam and then swing outward with a torn section of the foam layer and skin to form an opening in the cover for deployment of the air bag into the passenger space in the vehicle. The tear seam in the skin is formed with extremely small laser machined holes that are not observable to a person of normal vision when viewed from a normal viewing distance in the passenger compartment by having a maximum hole size dimension at the outer side of the skin that does not exceed about 0.0005 inches. The array of holes are arranged in a prescribed tear seam pattern and relative to each other so as to reduce the tensile strength of the skin along the tear seam by not more than about 50 percent whereby the structural integrity of the skin is maintained prior to air bag inflation but then on the occurrence of the latter, the tear seam will assuredly tear from the force of the inflating air bag to form an opening therefor in the skin.

Abstract: Method and apparatus including a powder box and heatable shell tool are disclosed for forming a thermoplastic automotive air bag cover skin with a lesser strength thermoplastic tear seam strip insert wherein the latter is initially formed with a protruding rib on one side and a pointed ridge on an opposite side. A heat resistant elastomeric transfer socket attached to the powder box interior receives and holds the insert rib and thereby the insert in a prescribed tear seam configuration and then positions the tear seam strip insert against a heated skin defining mold surface on the shell tool when the powder box is joined with the latter. The skin is formed by casting thermoplastic powder from the powder box against the heated mold surface and about the tear seam insert. The pointed ridge of the tear seam strip insert is pressed with a limited force against the heated mold surface by the transfer socket and prevents air entrapment between the tear seam strip insert and mold surface as the insert melts and joins with a surrounding layer of powder melt that forms the skin on cooling. In the process of melting, the pointed edge of the ridge and all of the rib of the insert melts and becomes part of a tear seam where the insert fuses with the skin while conforming to the mold surface to smoothly blend with the outer side of the skin while the backside of the insert smoothly blends with the surrounding inner side of the skin.

Abstract: A modular assembly for separating a passenger compartment from an engine compartment in an automotive vehicle body comprises three structural cross car members that combine to provide sufficient cross car stiffness between the side pillars so as to eliminate any need for an upper cross car beam at the cowl of the vehicle body. The three structural cross car members include a front of dash panel, an intermediate close out panel and an instrument panel carrier that form two rows of ducts for meeting the needs of the heating, ventilating and air conditioning system of the vehicle and the wiring requirements of the instrument panel. The instrument panel carrier is part of a covered instrument panel subassembly that includes a shell and an underlying foam cushion. The foam cushion is foamed in place in a mold that includes a slide and pivot mechanism for manipulating a mold lid and clamp between a closed clamped position and a shaping position where the molded subassembly is accessible for a shaping operation.

Abstract: Apparatus for manufacturing multiple color thin-walled hollow shells for parts such as automobile door panels, consoles and instrument panels from dry thermoplastic plastisol includes a supply box with a divider to form two or more compartments in the box. The box divider cooperates with selectively positioned split mold parts defining a separation in an open-ended heated mold for separating the mold into two or more sections. Complementary open ends of the charge box and mold are joined. Then the apparatus is rotated so that the powder is distributed into each mold section by gravity flow with the powder from each section flowing to the divider which separates the colors so as to form two or more tones on a resultant shell of cured material; thereafter the powder box is removed and the split mold parts are joined to clamp cast shell segments for fusion at a joint line.
