Abstract
Methods, devices and/or features which in addition to circumferential thrust neutrality additionally facilitate, permit or provide for thrust vector tuning of the inflation gas discharge from an inflator device. An end diffuser includes a diffuser wall defining a diffuser chamber for initially accepting inflation gas from a gas-providing portion of the inflator device. The diffuser wall includes a cylindrical portion having a plurality of inflation gas discharge openings disposed in a circumferential thrust neutral gas discharge array for discharging inflation gas from the diffuser chamber and an end wall portion forming a closed end to the diffuser. The end wall portion includes a protrusion of selected shape and dimensions extending therefrom into the diffuser chamber to create an inflation gas flow altering annular ring within the diffuser chamber to selectively thrust vector tune the inflator device.
