  • Publication number: 20090184497
    Abstract: In at least one embodiment of the present invention, an inflatable curtain for a motor vehicle is provided. The inflatable curtain is formed of layers of fabric and is deployable from a rolled state forming a roll to an inflated state. The air-bag comprises 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. 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. The air-bag further provides a gas flow duct. When the air-bag is in the rolled state, the gas flow duct is provided at the top part of the roll.
