Patent ID: 8202208

Claim:
An airbag folding method for folding like bellows an airbag comprising an airbag body formed of front and back base fabrics to be in a shape of a bag, and a tubular tether belt extending from a central position of the front base fabric toward an interior of the bag in a longitudinal direction thereof, said airbag folding method comprising: a step of causing one end of the tubular tether belt and the airbag body in sequence to ascend; a step of causing the raised tubular tether belt to descend by a distance corresponding to a length substantially equal to half a full length thereof; a step of pulling the other end of the tubular tether belt upward around one end of the tubular tether belt to thereby fold back the tubular tether belt at a position corresponding to substantially the middle of the full length thereof; a step of causing one end of the tubular tether belt to descend to thereby pull one end of the tubular tether belt with securing a position of the other end of tubular tether belt; a step of causing one end of the tubular tether belt to ascend to thereby fold the tubular tether belt; and a step of compressing the airbag body from above to thereby fold the airbag body.
