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: 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: 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: The present invention relates to an airbag cushion, which simultaneously exhibits a very low amount of fabric utilized to produce the target airbag cushion in correlation to an overall high amount of available inflation airspace within the cushion itself. These two correlative elements are now combined for the first time in what is defined as an effective fabric usage index (being the quotient of the amount of fabric utilized in the construction of the airbag cushion and the available inflation airspace volume). The inventive airbag cushion must possess an effective fabric usage factor of at most 0.0330. A cushion exhibiting such low seam usage and fabric usage factors 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: A modular airbag cushion system adaptable to different vehicle platform configurations comprises i) a plurality of separate, interconnectable inflatable airbag cushions each of which comprises at least one port for transmitting gas; ii) an optional connector for transmitting gas comprising a tube having a coaxial opening at at least one end, said tube being between and connected with at least two of said airbag cushions to provide a gas-tight connection between said ports; and iii) a gas source in communication with at least one of said ports for inflating said cushions in response to a signal. By varying the length of the connector or the ports, the system can be adapted to a variety of vehicle configurations using cushions of essentially the same length to protect outboard vehicle occupants from injurious contact with exposed interior sides of the vehicle in a crash.

Abstract: The present invention relates to air bag tethers and to a pattern-wise arrangement of such tethers in relation to air bag panels on a fabric blank, thus resulting in increased fabric utilization per tether and an overall cost savings per finished air bag. The air bag tether system of the present invention is comprised of two congruent tether panels that are joined to one another and to a respective air bag panel. In a preferred embodiment, the tether panel that is attached to the face panel of the air bag is cut in alignment with the warp and the fill of the fabric blank, while the rear tether panel that is attached to the rear panel of the air bag is cut on the bias with respect to the warp and the fill of the fabric blank. The two tether panels are then connected to one another to form a functional tether system. This two-piece construction, with one bias-cut piece, decreases the amount of fabric that is used in the manufacture of the air bag and tethers, while providing sufficient elongation for the tether system to be functional.
