US 6,485,403 B2 · Air bag system of folding an air bag

Abstract

A pouch-shaped air bag (12) is spread out in a circle. Then, the portion of the air bag (12) located outside the inflator (16) is folded into a wave-like pattern from four directions so that four side portions (61) are formed along the inflator (16). Next, each one of the four excess portions (62), which are continuously formed between each two adjacent side portions (61) and protrude outward, is placed along the outer face of each side portion (61). Thus, the air bag (12) can be easily folded compactly that can be smoothly unfolded.
