Abstract
An air bag installation is disclosed in which a flattened tube is expanded by a flow of pressurized gas from the air bag inflator or a separate source when the air bag system is deployed. The resulting tube expansion drives a cutting edge to sever an opening in a covering layer disposed over a substrate panel of an interior trim structure. A pyrotechnic charge may be used to augment the flow of pressurized gas. The tube may alternatively form an integral part of the instrument panel or the air bag assembly.
