Abstract: Provided herein are specific coating compositions, which are used as a monolithic coating layer for airbags. Preferably, these coating compositions are comprised of urethanes, which are blended together, where at least one of the urethane components is inherently flame retardant and the other of which is a urethane with gas-retaining properties. The gas-retaining urethane may be characterized as having high tensile strength at break, high elongation at break, and a 100% modulus less than 2,000 p.s.i. The inherently flame retardant urethane is the result of a manufacturing process in which a halogenated diol is reacted with an isocyanate, resulting in the incorporation of halogens into the polyurethane backbone. The resulting coating compositions (that is, the blends of gas-retaining urethane and flame retardant urethane), when applied as a single layer to an airbag fabric, result in an airbag with good gas retention, flame retardance, anti-blocking properties, and aging stability.

Abstract: An inflatable passenger restraint airbag having an inflatable and transferable gas vent is disclosed. A system and method is provided whereby the force of airbag deployment may be reduced in real time if the airbag strikes an out of position seat occupant. This force reduction is made possible by release of inflation gas at an early stage of deployment through an adjustable gas vent. This gas vent is operable between an open venting position and a closed non-venting position. Whether or not the transfer of the vent occurs in a given deployment situation is determined by the presence or absence of an out of position obstruction in the pathway of the airbag.

Abstract: The present disclosure is directed to the use of specific hybrid resins as airbag coatings. Preferably, the polymers used to create these hybrid resins, as described herein, are urethanes blended with acrylates, vinyls, silicones, and combinations thereof, where at least one of the components has a glass transition temperature of 20° C. or less. The urethanes are preferably of the polycarbonate, polytetramethyleneglycol, silicon-based diol, or olefin-based diol type. The hybrid resins may be produced in an aqueous dispersion, in a solvent, or by mixing the polymers together where one polymer is dissolved directly into a second polymer to form a continuous matrix. The resulting hybrid resins exhibit a tensile strength of at least 1,000 p.s.i. and an elongation at break of at least about 200%.

Abstract: A fabric construction utilizing a tying yarn knitting arrangement wherein a portion of the tying yarns are threaded to engage needles so as to form two stitches with one on either side of the inlay warp yarn at rows of stitch formation. The neighboring stitches resist yarn separation and resultant combing while also blocking the commencement and propagation of de-knitting when a tying yarn is broken thereby enhancing seam strength character.
