Abstract: An inflator (10) includes a container (12) having a chamber (120). An exit opening (48) is provided in the container (12) and is connected to the chamber (120). A substance (122, 180) is stored in the chamber (120) and is responsive to heat for providing inflation fluid. An igniter (130) is associated with the container (12) and is actuatable to provide combustion products for heating the substance (122, 180). A nozzle (80) is interposed between the igniter (130) and the chamber (120). A passage (90) extends from the igniter (130) and through the nozzle (80). The passage (90) includes a divergent portion (110) for focusing a flow of combustion products from the igniter (130) into the chamber (120).

Abstract: A method of filling containers (50) with gases (12) provides each container, when filled, with a first predetermined amount of a first gas and a second predetermined amount of a second gas. The method comprises the step of forming a mixture comprising first and second amounts of the first and second gases, respectively. The first and second amounts are greater than and are in proportion to the first and second predetermined amounts, respectively. The method further comprises the steps of: determining a sum of the first and second predetermined amounts; and adding a third amount of the mixture to each of the containers. The third amount is equal to the sum of the first and second predetermined amounts.

Abstract: An apparatus (10) for inflating an inflatable vehicle occupant protection device (32) comprises a container (20) defining a gas storage chamber (14), and inflation fluid (66) under pressure in the gas storage chamber. An opening (40, 42) in the container (20) enables fluid flow from the gas storage chamber (14) to the inflatable device (32). A rupturable burst disk (60, 62) extends across the opening (40, 42). An assembly (80) in the gas storage chamber (14) is provided for producing combustion products for heating and pressurizing the inflation fluid (66). The assembly (80) includes a housing (82) and a separator (100) in the housing defining first and second chambers (112, 114). A first pyrotechnic charge (122) in the first chamber (112) has a first burn rate. The housing (82) has first fluid outlets (96) for enabling flow of combustion products from the first chamber (112) to the gas storage chamber (14).

Abstract: An air bag inflator (10) includes a container (12) defining a chamber (14), and inflation fluid (66) under pressure in the chamber. A first opening (41) in the container (12) enables fluid flow from the chamber (14) to an inflatable device (32). A first burst disk (60) extends across the first opening (41) and is rupturable in response to an increase in the pressure differential across the first burst disk to a level above a first predetermined pressure differential. The inflator (10) includes a first igniter (90) for, when actuated, increasing the pressure differential across the first burst disk (60) to a level above the first predetermined pressure differential to rupture the first burst disk. A second opening (43) in the container (12) enables fluid flow from the chamber (14) to the inflatable device (32).
