AN INFLATABLE FABRICS AND AN AIR-BAG

摘要

The present invention relates to a inflatable double-layered fabric including an inflating part having gas inflatability, a non-inflating part supporting the inflating part, and a co-woven part constituting a boundary between the inflating part and the non- inflating part, wherein the inflating part is composed of two separated fabric layers, and the weave of the co-woven part is set up at a nk+1 pixel from the width or length end of the double-layered fabric (where, k is 2 or 3, and n is 0 or a positive number) when dividing the double-layered fabric into a plurality of pixels, an airbag including the same, and a method of preparing the airbag. The present invention also relates to a inflatable double-layered fabric including an inflating part having gas inflatability, a non-inflating part supporting the inflating part, and a co -woven part constituting a boundary between the inflating part and the non-inflating part, wherein the inflating part is composed of two separated fabric layers, and the non-inflating part includes a stepwise co-woven weave that is co-woven stepwise and alternately, and an airbag including the same. The present invention can block the gas leaking from the co-woven part effectively, when the airbag is inflated by the gas, to improve the perfomace for maintaing the internal pressure of the double-layered fabric.
