Abstract
A filter cloth for air bags comprises a synthetic fiber woven fabric having (1) a ground weave structure segment having a single plain weave structure or a single twill weave structure and (2) a plurality of high gas-permeability weave structure segments substantially evenly distributed in the ground structure segment, exhibiting an air permeability higher than that of the ground structure segment and having (A) a mock leno weave structure having pinholes, (B) a double plain weave structure or (C) a double twill weave structure, and allows, when an air bag is formed from the cloth, a layout for cutting and a cutting of the cloth to be made freely and when the resultant air bag is inflated, the bag allows an inflation gas to instantly flow out from the bag so as to ensure the safety of the occupant.
