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 is disclosed that 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.
An automotive protective device comprising a woven or non-woven textile substrate having an adhesive prime coat polyurethane layer coated on at least one surface thereof and a solid polymeric film laminated thereto.
A method of manufacturing an automotive protective device which comprises:
A method of manufacturing an automotive protective device which comprises:
A method of manufacturing an automotive protective device which comprises:
A composite sealing and air holding laminating film for use in the manufacture of an automotive protective device with a woven or non-woven textile substrate, said composite laminating film comprising a solid polymeric carrier film and a layer of adhesive prime coat polyurethane coated thereon.
A method of making a composite sealing and air holding laminating film for use in the manufacture of an automotive protective device which comprises:
An automotive protective device comprising a one-piece woven textile substrate having two outer surfaces and pre-configured air holding cavities woven therein, each of said outer surfaces having an adhesive polycarbonate-based aliphatic polyurethane prime coat layer and a solid polymeric film laminated to each of the outer surfaces of said woven textile substrate.
