Soft deployment air bag fold.

摘要

An air bag cushion is made of air bag fabric and has a mouth defined by a cushion retainer. The air bag cushion has a top and a bottom and an initially unfolded and uninflated condition. The air bag cushion when in the initially unfolded and uninflated condition is positioned with the bottom facing up and the mouth at a central side position. Folding of the air bag cushion is effected by a succession, one after the other, of tucks and rolls comprising the centre of the fabric being tucked towards the mouth of the air bag cushion to create an upper pleat and a lower pleat. The lower pleat with the upper pleat is rolled towards the mouth of the air bag, stopping after about half of the fabric of the air bag cushion is rolled up. One side of the rolled cushion fabric is tucked to the adjacent edge of the cushion mouth inside of the cushion between the upper and lower pleats. The opposite side of the rolled cushion fabric is tucked to the adjacent edge of the cushion mouth inside of the cushion between the upper pleat and the lower pleat.
