摘要： A dual flow inflator for airbags is disclosed, together with related manufacturing, installation, and deployment methods. The inflator may have a gas chamber with a first end with a first exit orifice and a second end with a second exit orifice. The exit orifices may be directed into inlet ports of an inflatable curtain so that inflation gases exit the inflator through the exit orifices and enter directly into the inflatable curtain. The exit orifices may provide axial gas flows in opposite directions so that each gas flow neutralizes the thrust of the other. The exit orifices may comprise frangible structures such as burst discs, scored surfaces, and compression closures. If desired, pistons may be utilized to ensure that the exit orifices are completely and simultaneously opened. Furthermore, the gas chamber may comprise a variety of configurations, including a unitary, one-piece structure, a multi-part structure with vessels attached to a tubular or spherical bulkhead, or a generally spherical shape.
