Abstract
Air bags for vehicles are disclosed. The air bags are made from a composite material comprising at least one film layer attached to a plurality of reinforcing elements. For instance, in one embodiment, a plurality of reinforcing elements may be located in between a first film layer and a second film layer. In one embodiment, each film layer may comprise a multilayer film. The composite material is particularly well suited to forming side-curtain air bags.
