US Patent 7353669 Air bag fabric and inflatable elements formed therefrom

An air bag substrate fabric utilizing a tying yarn knitting arrangement wherein a portion of the tying yarns are threaded to engage needles so as to form two stitches with one on either side of the inlay warp yarn at rows of stitch formation.
