Abstract
A woven textile fabric is disclosed which is formed of synthetic yarns of at least two different deniers to which a solid polymeric film is laminated. An adhesive polymeric coating is provided for adhering the solid polymeric film to the woven textile fabric. The combination of yarns of different deniers provides a superior adhesion surface for the polymeric film. The yarns and the polymeric coating are preselected respectively in deniers and thicknesses so as to render the fabric substantially impermeable to fluid under pressure, while maintaining superb packageability and anti-blocking properties for use in vehicle occupant restraint systems. An air bag incorporating the woven textile fabric of the invention and having two outer surfaces and pre-configured air holding cavities woven therein to which a solid polymeric film is bonded for receiving and containing fluid under pressure for use in a vehicle air restraint system is also disclosed. Air vents are provided for preventing entrapped air from forming bubbles in the lamination process.
