Abstract:
A method for forming a design in a panel includes providing an outer panel layer on an inner panel layer to form a single composite panel including two layers. The design is then formed into the panel by forming voids in the outer layer. The voids are formed by exposing predetermined regions of the outer layer to a laser beam that burns, vaporizes or otherwise removes portions of the outer layer in each exposed region. The voids create the design by exposing the inner panel layer.
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:
A vehicle passenger compartment floor console includes a module receptacle and a plurality of interchangeable storage and appliance modules designed to fit within the module receptacle. The floor console may also include a drum-type carrousel supported for rotation about a generally horizontal axis within the console outer shell. The carrousel holds three storage modules and is positioned to sequentially rotate each module past an access opening cut or formed through the console outer shell. A passenger compartment occupant may use the console to selectively present any one of a number of interchangeable modules for occupant access while traveling.
Abstract:
An air bag occupant restraint system (10) for a vehicle comprises an inflatable cushion (14) adapted to inflate in the event of a vehicle collision. A gas generating device (16) in communication with the cushion (14) inflates the cushion. The cushion (14) includes a transparent portion (18) disposed on at least a portion of the interior of the windshield (12) when in the collapsed state. With this arrangement, the transparent portion (18) can inflate to inhibit the occupant from colliding with the windshield (12) and other objects adjacent to the windshield in the event of a collision. Similarly, the inventive method for cushioning a vehicle occupant in the event of collision comprises the following steps. First, dispose an inflatable cushion (14) over the windshield (12) of the vehicle when the cushion is in an uninflated state. Next, communicate the cushion (14) with a gas generating device (16) adapted to inflate the cushion in the event of a collision. Then, sense when a collision occurs. If a collision occurs, inflate the cushion (14) with gas.
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 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 thin-walled hollow shells for parts such as automobile door panels, control and instrument panels and the like includes a charge box or powder box for supplying dry thermoplastic material to separate casting surfaces on a heated mold selectively connected to the charge box during a casting process. A selectively pressurizable inflatable seal gasket is connected to the charge box for sealing a division surface on the heated mold which surface separates the casting surfaces of the mold. The inflatable seal gasket includes a base portion fixed to the charge box; an inflatable core with expandable walls to bridge the distance between the charge box and the division surface and a seal bead that sealingly engages the division surface when the seal gasket is inflated to keep the division surface clean for a subsequent application of material to form a connector bond between previously cast two tone colored segments.
