Abstract
A variety of embodiments are disclosed, in both apparatus and method form, that relate to the use of fabric material in the manufacture of an air bag deployment system. In addition, fabric weakening is disclosed according to a technique that does not result in physical alteration of the fabric. This invention therefore includes an air bag cover for an air bag safety system for a vehicle comprising a fabric outer layer having a frontside and a backside and a substrate containing an opening wherein the opening has a periphery. The substrate is preferably formed by low pressure molding, wherein the fabric outer layer overlies the opening in the substrate, and wherein the fabric outer layer is weakened at a location that is adjacent or overlies the substrate opening periphery.
