Abstract:
1. An inflatable curtain for a motor vehicle formed of layers of fabric and being deployable from a rolled state forming a roll to an inflated state, the air-bag comprising part of the air-bag that forms the upper-most edge of the air-bag when the air-bag is in the inflated state extending downwardly from the roll to lie proximate a side part of the motor vehicle on which the air-bag is to be mounted, wherein at least a portion of the roll is positioned above the upper-most edge in the rolled state and is driven downward below the upper-most edge during deployment to the inflated state, wherein the air-bag further provides a gas flow duct, and when the air-bag is in the rolled state the gas flow duct extends along a top-most part of the roll such that during deployment the gas flow duct initially inflates driving a remaining portion of the roll downward to facilitate deployment to the inflated state, wherein the air-bag is rolled to form the rolled state in a direction towards the outboard side of the air-bag, wherein in the rolled state the upper-most edge extends downwardly from the roll without having a fold formed therebetween, and at least an upper half portion of the roll is positioned above the upper-most edge.
