Abstract
A multi-layered woven side air curtain has pre-configured air holding cavities and a polymeric film laminated thereto. An adhesive polyether polyurethane or polyester polyurethane prime coat layer is first coated onto a textile substrate, and then a polymeric film, such as polyamide, polyolefin, or polyurethane is laminated thereto. The textile substrate may be woven of nylon, polyester, or other synthetic fibers. According to an alternative embodiment, a multi-layered composite film product can be used as a film laminate without the need for a prime coat adhesive layer being first applied to the textile substrate. In such a case, the adhesive prime coat is applied to the textile substrate in a single step via the film laminate itself. The side air curtain can be pre-configured or prefabricated to numerous varied designs and shapes prior to coating.
