Patent ID: 7380819

Claim:
An air-bag arrangement comprising an inflatable element and a gas generator configured to inflate the inflatable element, the inflatable element defining at least first and second chambers for inflation by a gas from the gas generator, a gas-supply duct being rigid and having an end-outlet aperture formed through an end-wall of the gas-supply duct so as to have a diameter smaller than the bore of the gas-supply duct, and at least one side-outlet aperture formed through a side-wall of the gas-supply duct at a position substantially adjacent the end-outlet aperture, the end-outlet being configured to direct gas out of the gas-supply duct in a first direction substantially orthogonal to a second direction of gas directed through the side-outlet aperture, wherein the gas-supply duct extends from the gas generator through an inlet sleeve of the inflatable element and into an interior volume of the inflatable element so as to direct gas from the gas generator to the first chamber through the end-outlet aperture, and direct gas from the gas generator to the second chamber through the side-outlet aperture.
