ABSTRACT:
An inflatable airbag (10) for restraining an occupant in a vehicle which is first laid out flat and turned inside out before being rolled into the form of a bag roll. The entire bag is consumed in the roll and the rolling step is continued until the bag roll passes into and through the mouth (14) of the bag thus inverting the entire bag pack so that the roll now stands in front of the bag mouth (14) and on front of the pack. As deployment of the air bag inflator pushes the roll away from the canister, the cushion unrolls in a downward motion toward the lap of the occupant. Because the roll is slightly trapped within itself, the cushion is free to inflate to the sides but must overcome resistance to extend away from the canister. Ultimately, the deployment action of the inverted roll cushion is more lateral and less extended than other known folds.
