Abstract: A cover for an air bag module is provided. The cover comprises a polymeric sheet and one or more thinned portions. The polymeric sheet has a first surface and a second surface and includes a plurality of cells formed therein. A skin is formed on at least the first surface. The thinned portions are formed in the second surface and define a weakened region of the cover.

Abstract: In one embodiment, the method to produce a foamed material with variable cross-linking comprises mixing a first resin, a first blowing agent, and a first cross-linking agent to form a first mixture and mixing a second resin, a second blowing agent, and a second cross-linking agent to form a second mixture and cross-linking the first mixture and the second mixture such than the amount of cross-linking in the first mixture differs from the amount of cross-linking in the second mixture. The first mixture and second mixture may be co-extruded to form an extrudate having a varying amount of cross-linking across the thickness of the extrudate. The blowing agent is activated to result in a foamed material.

Abstract: A fastener assembly for detachably connecting a molded door trim panel to an apertured inner door panel of a vehicle, where upon disassembly, the fastener assembly will disengage, or a replaceable portion will fracture without damaging the molded door trim panel. A detent is utilized to connect a hook portion to a retainer housing that is molded into the molded door trim panel. Upon the hook portion being mistakenly pulled against the inner door panel during disassembly, the detent will either disengage the hook portion from the retainer housing, or the hook portion will fracture before the retainer housing is damaged or disconnected from the molded door trim panel. By preventing damage to the retainer housing and molded door trim panel, only the hook portion of the hook fastener assembly need be replaced or reconnected, instead of the entire molded door trim panel.
