    Abstract: A fabric for use in an air bag is provided. The fabric of the invention is produced by mechanically compressing a preliminary fabric constructed substantially of synthetic yarn such that the packed volume per unit area of the compressed fabric is less than the packed volume per unit area of the preliminary fabric. Air permeability is not adversely affected.

    Abstract: The present invention relates to a vehicle restraint system which comprises an airbag into which an inflator can assembly may be placed. The inventive airbag preferably comprises two body panels, attached by one substantially straight seam, and a separator panel which, upon folding and attaching of the two body panel sections of the airbag produces a mouth (looped pocket) for holding of the above-mentioned inflator can assembly. Such an article allows for quick and complete inflation upon release of propellant and facilitates packing in a standard restraint system enclosure. The invention thus encompasses both the restraint system and the airbag itself.

    Abstract: The present invention relates to an airbag fabric which is woven in such a manner as to possess a cover factor of less than about 1900 but which simultaneously, through the presence of a film (laminate) or coating, possesses an extremely low air permeability. The utilization of such a loosely constructed fabric within airbag cushions has heretofore not been possible, even with the application of standard airbag coatings (such as silicones) over the fabric surface since such coatings with not easily remain in contact over the loosely constructed fabric surface (i.e., the coating would leak through the fabric). The coupling of a low cover factor fabric with a laminate film (or with a coating wherein the cover factor is at least 1600), however, solves such a problem and permits the utilization of inexpensively produced woven fabrics within airbag applications.

    Abstract translation: 本发明涉及一种气囊织物，其以这样的方式编织，即具有小于约1900的覆盖系数，但是通过膜（层压体）或涂层的存在同时具有极低的透气性。 迄今为止，即使将织物表面上的标准气囊涂层（例如硅树脂）应用于织物表面上也是不可能的，因为这样的涂层不容易在松散构造的织物表面上保持接触 即涂层会渗透织物）。 然而，低覆盖因子织物与层压膜（或覆盖因子至少为1600的涂层）的耦合解决了这样的问题，并且允许在气囊应用中利用廉价生产的织造织物。

    Abstract: An airbag fabric has a finish on a surface thereof, the finish comprising a plurality of particles having a diameter of about 20 μm or less. A process for producing a coated airbag fabric comprises the steps of (a) providing an airbag fabric, (b) contacting at least one surface of the airbag fabric with a coating composition comprising a plurality of particles having a diameter of about 20 μm or less, and (c) drying the fabric treated in step (b) to produce a finish on the airbag fabric.

    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.
