ABSTRACT:
A method of forming an air bag which includes the steps of weaving on a loom an upper and lower fabric simultaneously, the two fabrics being combined in selected areas to define a seam of substantially circular shape. A bag is produced by cutting within the seam. The bag does not have an additional coating, but the permeability of the bag is determined by controlling the sett thereby utilizing the permeability of the weave itself.
