    Abstract: An airbag construction for a vehicle is described. The construction utilizes non-circular polygon shaped panels, which provide greater nesting efficiency than previously achieved by comparable airbags using round panels. In addition, the construction enables the airbag to take full advantage of the strength of the yarns forming the fabric, and the energy absorption of the fabric construction, enabling the use of lower tenacity yarns and/or materials at comparable levels of performance.

    Abstract: An airbag cushion for use in a vehicle restraint system is provided. The airbag cushion is formed from two body panel sections of substantially similar straight line geometry which are joined to one another by two substantially straight seams along corresponding lateral boundary edges. The upper boundary edges of the body panels which are not joined to one another are joined around the perimeter of a rectilinear center panel by a series of substantially straight seams. A method of forming the cushion according to the present invention is also provided.

    Abstract: The present invention relates to multi-segment air bag tether panels and to a pattern-wise arrangement of such tether segments in relation to air bag panels on a fabric blank. In one embodiment, the tether panel is comprised of two or more tether segments that are cut in substantial alignment with the warp or the fill of the fabric blank. The tether panels are then connected to one another along their tether-attachment ends to form a functional tether system. This multiple-segment construction 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.

    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 method utilizing welds, reinforced with sewn seams, to adhere two fabrics together to form an inflatable airbag cushion. Although welded seams provide better and more easily produced attachment points between multiple layers of fabrics, not to mention improved manners of reducing air or gas permeability as such attachment points, the utilization of sewn seams adjacent to such welded areas provides stronger reinforcement, and thus more reliable non-permeable fabrics. Seam welding generally concerns the utilization of a film on the underside of a fabric which, upon contact with a second, film-treated fabric and upon exposure to high frequency energy, forms a bead of polymeric material at the attachment point between the two fabric layers. Lower numbers of sewn seams may be utilized to permit sufficient reinforcement if the size of the formed polymeric bead if of sufficient size to permit thorough sealing and adhesion between the fabric layers. Such a specific reinforced fabric, as well as high bead-size welded airbag fabrics are encompassed within this invention.

    Abstract: An inflatable restraint cushion for use in transportation passive restraint systems is provided. The inflatable restraint cushion according to the invention is of a foldable construction having two panels. The first panel is of generally a pyramidal configuration while the second panel is of an elongated rectangular configuration joined to and extending from the apex of the first panel. The first panel is divided into right and left segments along a center fold line. The right and left segments each contain corresponding depressed sections. The right and left segments of the base are folded towards one another and are seamed together. The second panel is thereafter folded in loop fashion towards the first panel and a single seam is used to join the mating edges of the first and second panels. The presence of the depressed sections results in a cushion configuration having a depressed lower profile which is capable of engulfing the instrument panel of the vehicle.

    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.
