Abstract
The invention is directed to textile fabrics for use in air bags and side curtains having at least one coating layer of polyvinyl chloride thereon. The textile fabric can be a flat sheet, such as used in driver side air bags, or a multi-layered woven textile having preconfigured air-holding cavities therein for use in side curtains such as are installed in sport utility vehicles (SUVs). In certain embodiments of the invention coating layers of elastomeric polyurethane may be applied to the textile fabric in addition to the coating layer of polyvinyl chloride. In certain instances, the textile fabrics are coated on one side only, and in others they may be coated on both sides, i.e., on opposed first and second surfaces. In either case, the polyvinyl chloride coatings, whether alone or in combination with other polymeric coatings, provide the air bags or side curtains with superior air-holding characteristics.
