摘要： A multiple-chamber inflator (10) for a vehicle occupant protection system. The inflator (10) includes a housing (12) having a first end and a second end, and a divider disc (18) positioned in an interior of the housing (12) intermediate the housing ends to form a first (primary) propellant chamber (20) and a second (secondary) propellant chamber (22) within the interior of the housing (12). The divider (18) has a first surface (59) in communication with the first propellant chamber (20), a second surface (57) in communication with the second propellant chamber (22), and at least one aperture (60) extending between the first and second surfaces to provide fluid communication between the first propellant chamber (20) and the second propellant chamber (22). A pressure-resistant shim (62) fabricated from a low-melting point material is fixed on the divider first surface (59) over the at least one aperture (60) to block the aperture. The shim (62) is configured to melt upon exposure to a predetermined temperature generated by combustion of the propellant (48) in the first propellant chamber (20), thereby opening the at least one aperture (60). The shim (62) isolates the first chamber (20) from the second chamber (22). The shim (62) also facilitates an increase in pressure in the first chamber (20) during combustion of the first gas generating propellant (48), thereby increasing the efficiency of the combustion reaction in the first chamber (20).

An oxidizer is combined with the fuel and preferably contains phase stabilized ammonium nitrate. A novel method of forming the compositions is also presented wherein the various constituents are wetted and/or dissolved, and then cured within the polyvinylazole matrix thereby forming a more intimate combination within the gas generant composition. A vehicle occupant protection system 180, and other gas generating systems, incorporate the compositions of the present invention.

摘要： An inflator (10) comprising a housing (12) having an interior and a plurality of gas exit orifices (14) formed therealong. A gas source material (20) is positioned in the housing interior and is enclosed in a pliable, rupturable substantially gas-and-moisture-impermeable container (24). The gas source (20) is a material (for example, hydrogen peroxide) adapted to undergo decomposition to form at least one gaseous decomposition product comprising an inflation gas. A reactant material (22) is also positioned in the interior of the housing (12). The reactant (22) is a material (such as a catalyst) adapted to react with the gas source material to produce decomposition of the gas source material (20). An enclosure (28) is positioned within the housing (12) to form a cavity (30) between an outer wall of the housing (12) and the enclosure (28). The reactant material (22) is positioned in the cavity (30). A plurality of orifices (34) formed along the enclosure (28) enables fluid communication between the interior of the enclosure (28) and the cavity (30). The container (24) is positioned in the enclosure (28). A resilient, expandable bladder (42) is also positioned in the enclosure (28). A propellant (44) is provided within the bladder (42) for generation of combustion gases upon ignition of the propellant (44), to produce expansion of the bladder (42). Upon ignition of the propellant (44), combustion gases expand the bladder (42), forcing a portion of the container (24) into the enclosure orifices (34), thereby stressing and rupturing the portions of the container (24) in the orifices (34) and releasing the hydrogen peroxide (20) to flow through the orifices (34) into the cavity (30), where it reacts with the catalyst (22) to produce inflation gas.
