Airbag fabric processing very low cover factor

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.

Inflatable fabric with peel seams

The invention relates to inflatable fabrics which comprise two separated and distinct fabric layers in discrete areas of such fabrics as well as connecting seam-producing materials to which such fabric layers are simultaneously attached. The resultant inflatable fabric composite thus includes inflatable areas separated, at least partially, by seamed barrier areas. This configuration will form 'pillowed' structures within the target fabric upon inflation. Such connecting seam-producing materials are incorporated within the two-layer structure as peel seams in relation with the individual fabric layers. Upon inflation, the seams then act as shear seams which greatly increases the overall strength of the two-layer inflatable fabric. These shear seams thus provide a relatively effective manner of reducing air permeability within the entire fabric article. Such a fabric may be utilized in numerous and various applications wherein fabric inflation is desired or necessary. In particular, the inventive fabric may be incorporated within an airbag cushion.

Abrasion and/or puncture resistant fabrics, airbag cushions, and methods

Typical road surfaces are concrete, and gravel filled asphalt. They are very abrasive to fabrics that slide on those surfaces. For the new side impact curtain-type airbag, in a rollover situation, the airbag needs to protect the occupant from directly contacting the road hazard and should not deflate quickly or break when sliding on such road surfaces. We have found that a layer of elastomer can provide much better abrasion resistance than a layer of heavy industrial fabric. A Jacquard bag coated with 1.2 oz/yd 2 polyurethane showed significant increase in air leakage rate after 5 cycles of concrete sliding abrasion. A 3 mil thick polyurethane film was laminated to the coated Jacquard woven airbag. After 110 cycles of sliding abrasion using the same concrete, no visual damage or change in bag leakage was observed. This finding indicates surprisingly better abrasion resistance of a thin elastomer film than a heavy industrial fabric.

Multiple chamber airbag and method of producing the same

Airbag fabric possessing a very low cover factor

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 will 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.

Simplified air bag configuration

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.

Airbag with flame retardant monolithic coating layer

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.
