Abstract
Vehicular air bags formed from multilayer composites. The multilayer composites include a polymeric film and at least one tear resistant fabric attached to the polymeric film, and more particularly include a polymeric film, an open mesh, tear resistant fabric attached to the film and a fabric layer attached to the open mesh, tear resistant fabric. Air bags formed therefrom have low base weight, low elongation and high tear propagation resistance, protecting vehicle occupants from injury during and after air bag deployment.
