Patent

CA 2429770

A side curtain air bag assembly is provided, which has an inlet configured to receive inflation gas, a plurality of inflatable chambers; and a distribution tube in fluid communication with the inlet of the air bag. The inlet and the distribution tube are configured to cause inflation gas to flow along the air bag in a predetermined direction, and the distribution tube has a conical portion configured to reduce the pressure of the inflation gas pressure that is communicated from the inlet, and to distribute the inflation gas to the inflatable compartments of the air bag. The air bag is stored with the distribution tube wrapped about an inboard side of the air bag and in a manner such that the distribution tube unwraps from the air bag and is positioned between the inboard side of the air bag and the adjacent side structure of the vehicle as inflation gas is being initially communicated to the distribution tube, thereby enabling the air bag to deploy without interference with gaps that may exist (or may form) at the adjacent side structure of the vehicle.
