    摘要： 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.

    摘要翻译： 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。

    摘要： An air bag substrate fabric 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.

    摘要： 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.

    摘要： An airbag and a method for making an airbag of the type that includes an irregularly-shaped panel, such as the side panels of a passenger airbag. The irregularly-shaped side panel is first divided into two segments with a single straight line to define an inflation segment and an impact segment. The straight line drawn to define the largest polygon that can be defined by any single straight line without coming too close to the inflation module hole. By segmenting the larger, irregularly shaped panel into two smaller ones with one of those being polygonal, better nesting of the segments can be obtained, which significantly improves fabric utilization to offset the labor cost from sewing the two segments together when making the irregularly shaped side panel required for the airbag.

    摘要： The present invention relates to an airbag cushion which simultaneously exhibits a low amount of seam usage (in order to attach at least two fabric panels or portions of a single panel together) as well as a very low amount of fabric utilized to produce the target airbag cushion, both in correlation to an overall high amount of available inflation airspace within the cushion itself. These two separate, but correlated factors, one based on an effective seam usage index 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) and the other based on an effective fabric usage index (being the quotient of the amount of fabric utilized in the construciton of the airbag cushion and the available inflation airspace volume). The inventive airbag cushion must possess an effective seam usage factor of at most 0.11 and 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.

    摘要： The present invention relates to air bag tethers formed from multiple bias-cut tether segments. Groups of tether segments are attached to the front and rear air bag panels and are then connected to one another to form a functional tether system. This multiple-segment construction, with its bias-cut segments, 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.
