    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: The present invention relates to an airbag cushion which exhibits a low amount of seam usage (in order to attach at least two fabric panels or portions of a panel together) in correlation to an overall high amount of available inflation airspace within the cushion itself. These correlated elements are now combined for the first time in what is defined as an effective seam usage index (being the quotient of the length of overall seams on the cushions and the available inflation airspace volume). The inventive cushion must have at least one substantially straight seam and must possess an effective seam usage factor of less than about 0.11. A cushion exhibiting such a low seam usage factor and also comprising an integrated looped pocket for the disposition of an inflator can is also provided as well as an overall vehicle restraint system comprising the inventive airbag cushion.

    Abstract: Airbag cushions manufactured from polyester yarn having certain levels of intrinsic viscosity (IV) and certain specific carboxyl end group (“CEG”) levels perform unexpectedly well in high temperature and high humidity environments for airbag cushion applications. This specification identifies certain polyester yarns and characteristics of such polyester yarns that are necessary to achieve unexpectedly good performance in such high humidity and high temperature applications. A polymeric polyester yarn for airbags, said yarn having a high degree of tenacity even after a long period of exposure to high temperature and high humidity conditions is disclosed. In one aspect of the invention, a polyester yarn having CEG of less than about 60 equivalents/106 gram, and more preferably less than about 30 equivalents/106 grams, is particularly useful. In another embodiment, a polyester yarn having an IV value of at least about 0.6 performs exhibits superior properties.

    Abstract: An inflatable side protection airbag having a first panel and a second panel, in which the first panel and second panel each have an anterior portion and a posterior portion. The first panel may comprise the outboard portion of the inflated structure. The second panel may be formed in separate fabric pieces which are sewn together, reducing the overall amount of fabric required to construct the second panel. A bridging portion may be provided in the second panel. The bridging portion may be provided adjacent a void area which is positioned at least partially between the anterior portion and the posterior portion of the second panel. An anterior portion of the first panel is mated to the anterior portion of the second panel in forming a front pillow. A posterior portion of the first panel is mated to the posterior portion of the second panel to form a back pillow. The ratio of the amount of fabric actually employed in the final product to the amount of fabric blank utilized for the construction may be as much as eighty or even ninety percent or greater for some designs.

    Abstract: An airbag having low gas permeability characteristics. The airbag is formed from two separate layers of material, an inner layer having low air permeability and an outer strength layer enclosing the inner layer, where the layers are only attached together along seam lines. The inner layer is made from a film material, preferably urethane. The outer layer is formed from a fabric.
