Abstract: Cool burning gas generant compositions for an automotive inflatable restraint system are provided that include a bismuth-containing compound selected from the group consisting of: bismuth citrate, bismuth subsalicylate, bismuth hydroxide, copper bismuth hydroxy nitrate, bismuth subcarbonate, bismuth suboxalate, and combinations thereof. The gas generant comprises at least one copper-containing component. The gas generant includes at least one oxidizer, fuel, and optional coolant. The maximum flame temperature at combustion (Tc) of less than or equal to about 1700K (1,427° C.). The cool burning gas generant composition generates liquid phase combustion products making it suitable for use in a filterless inflatable restraint system. Copper and bismuth present in the cool burning gas generant composition react to form an alloy having a melting point at or near the maximum flame temperature at combustion (Tc).

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.
