Embodiment Construction

[0030] refer to figure 1 , shows a close-up view of warp yarn fibers 1 and weft yarn fibers 2 forming a fabric 3 for manufacturing an inflatable airbag. Each warp fiber 1 passes alternately under and over the weft fibers 2 it encounters along its length. Similarly, each weft fiber 2 passes alternately under and over the warp fibers it encounters along its length.

[0031] exist figure 1 In the embodiment shown, both warp 1 and weft fibers 2 are at least partially coated with an adhesive substance to increase the friction between warp 1 and weft 2 fibers in the woven fabric 3 . It will be appreciated that the increased friction generated at the intersection point 4 between warp fibers 1 and weft fibers 2 will prevent relative movement of said fibers 1, 2 with respect to each other, thus increasing the stability and overall strength and reliability of the fabric 3. sex.

[0032] In an embodiment of the invention, the warp yarn fibers 1 and the weft yarn fibers 2 may be compl...

Abstract

A fabric for use in the manufacture of an inflatable airbag, the fabric comprising interwoven warp and weft fibers aligned substantially perpendicular to one another, one or more of the warp and weft fibers being at least partially coated with an adhesive Substance to increase the friction between warp and weft fibers at their intersection points.

Description

technical field [0001] The present invention relates to fabrics for use in the manufacture of inflatable airbags, and methods of making said fabrics. Background technique [0002] Inflatable airbags used in occupant restraint systems in motor vehicles are typically formed from woven fabrics. These fabrics generally include two groups of fibers called warp fibers and weft fibers, which are interwoven with each other and arranged at approximately right angles to each other. Coatings are often applied to these fabrics, and the coatings provide the function of reducing the permeability of the material, as well as keeping the fibers in place. [0003] It is advantageous to reduce the weight of the airbag as much as possible. Not only would this reduce the amount of material required to construct the airbag, thereby reducing the cost of the finished product, but it would also reduce the weight that a vehicle incorporating the airbag would have to transport. [0004] With regard...
