Abstract
Abstract An air bag, when inflated, is in the form of a substantially rectangular bag having a front edge, two side edges, and a rear edge. The air bag is folded in such a manner that the front edge approaches the rear edge and the two side edges are each folded inwardly at predetermined intervals, forming first creases which lie perpendicular to the side edge portions, and a pair of opposing walls located between the front and rear edges which are each folded inwardly at predetermined intervals, forming second creases which are positioned perpendicular to the side edges and are continuous with the first creases.

Independent Claim
154 words
An air bag for use in an air bag device and having a substantially rectangular form when inflated, comprising: a rear edge along which an inflator for supplying an inflating gas is attached; two side edges which extend from opposing ends of said rear edge so as to be substantially parallel with each other; a front edge; and a pair of walls located between said front and rear edges so as to define two opposing faces of the air bag when inflated, and said air bag when folded comprises: said two side edges folded inwardly forming first creases in said two side edges, and said pair of walls folded outwardly to form second creases which are perpendicular to said first creases and continuous with said first creases; and said front edge being located closer to said rear edge than when inflated, so that said front edge is located in front of said rear edge.
