Abstract
The invention is directed to multi-layered textile fabrics having a plurality of polymeric coating layers of polyurethane and/or polysiloxane coated thereon. The coating layers are applied to such multi-layered woven textile fabric substrates having preconfigured air-holding cavities therein to form an improved air-holding vehicle restraint system, such as an air bag or side air curtain with superior air-holding characteristics. In certain instances, the multi-layered textile fabrics are coated on one side only, and in others they may be coated on both sides, i.e., opposed first and second surfaces. The layers of the multi-layered fabric can then be joined by means of heat sealing, RF welding or combinations thereof, for purposes of forming an air bag or side air curtain without the need for sewing or stitching. The coated fabrics facilitate manufacture of air bags, side curtains or the like with both reduced cutting and sealing steps than fabrics of the prior art.
