Patent ID: 7770607

Claim:
A woven, double-yarn fabric for an inflatable airbag, the fabric comprising: a non-inflatable fabric portion comprising a single, woven fabric layer; and an inflatable fabric portion surrounded by the non-inflatable fabric portion; wherein the inflatable fabric portion comprises a first woven fabric layer and a second woven fabric layer that is opposite from the first woven fabric layer to define at least one inflatable cell to be inflated; wherein the opposing woven fabric layers of the inflatable fabric portion are formed from a plurality of first yarns forming a first, second, third, and fourth sets of first yarns, and a plurality of second yarns oriented substantially laterally to the plurality of first yarns; wherein the first set of first yarns is woven under a first adjacent pair of second yarns while the third set of first yarns is woven over the first adjacent pair of second yarns, and the first set of first yarns is woven over a second adjacent pair of second yarns while the third set of first yarns is woven under the second adjacent pair of second yarns, forming a first weaving pattern, the first weaving pattern being repeated to form the first woven fabric layer; and wherein the second set of first yarns is woven under a third adjacent pair of second yarns while the fourth set of first yarns is woven over the third adjacent pair of second yarns, and the second set of first yarns woven over a fourth adjacent pair of second yarns while the fourth set of first yarns is woven under the fourth adjacent pair of second yarns, forming a second weaving pattern, the second weaving pattern being repeated to form the second woven fabric layer; and wherein the non-inflatable fabric portion is formed through weaving the first and second sets of first yarns over a fifth adjacent pair of second yarns while the third and fourth sets of first yarns are woven under the fifth adjacent pair of second yarns, and weaving the first and second sets of first yarns under a sixth adjacent pair of second yarns while the third and fourth sets of first yarns are woven over the sixth adjacent pair of second yarns, forming a third weaving pattern, the third weaving pattern being repeated to form the single, woven fabric layer.
