    摘要: A vehicle occupant restraint apparatus (10) includes an inflatable vehicle occupant restraint (12) and an inflator (14) for providing gas for inflating the restraint (12). The inflator (14) contains an ignitable gas generating material (70) which, when ignited, generates the gas. The inflator has a structure (72) which defines a combustion chamber (78) containing the gas generating material (70). The inflator (14) further has an axis (66), and directs the gas to flow from the combustion chamber (78) outward through the inflator (14) and outward from the inflator (14) in a direction transverse to the axis (66). The inflator (14) is free of a tubular body wall defining gas flow openings at a location outward of the structure (72) defining the combustion chamber (78).

    摘要: An apparatus for inflating a vehicle occupant restraint includes containing means for receiving gases to provide a combustible mixture of the gases. An igniter is activated to effect ignition of the mixture of gases in response to sudden vehicle deceleration. A directing means directs a flow of gas from containing means into the inflatable occupant restraint. In the preferred embodiment the gases are an inert gas, a fuel gas, and an oxidizer gas. Also, a lean mixture of a fuel gas and oxidizer gas could be used. An improved igniter transmits energy through an imperforate portion of a wall of the containing means to ignite a charge in the containing means. The igniter may include an elongate core disposed in a frangible sheath which is shattered as the core is burned.

    摘要: An apparatus for use in inflating an inflatable vehicle occupant restraint (12) comprises a grain (110) of ignitable gas generating material which, when ignited, generates gas for inflating the vehicle occupant restraint (12). The grain (110) of gas generating material has a surface portion defining a cavity (124) in the grain (110). The apparatus further includes a plug (160) of pyrotechnic material which is more readily ignitable than the gas generating material. The plug (160) of pyrotechnic material, when ignited, produces and emits combustion products which ignite the grain (110) of gas generating material. The plug (160) of pyrotechnic material is located in the cavity (124) in the grain (110) of gas generating material.

    摘要: An inflatable vehicle occupant restraint system comprises a source of inflation fluid (20) and an air bag reaction canister (24) having a vent opening (16) through which inflation fluid from the source of inflation fluid (20) may be vented away from the air bag canister (24). An air bag (12) is located in the air bag reaction canister (24) and is inflatable by inflation fluid from the source of inflation fluid (20). A valve member (30) is located on the air bag reaction canister (24). The valve member (30) is movable relative to the vent opening (16) in response to ambient temperature variations in the vicinity of the source of inflation fluid (20) to control venting of inflation fluid from the source of inflation fluid (20) through the vent opening (16). Inflation of the air bag (12) is thereby controlled in response to ambient temperature variations in the vicinity of the source of inflation fluid (20).

    摘要: An apparatus (10) for inflating an inflatable vehicle occupant restraint (12) includes a collision sensor (52) and an inflator assembly (20). The collision sensor (52) provides a collision signal indicating the occurrence of a vehicle collision. The inflator assembly (20) includes a first source (22) of inflation fluid which, when actuated, provides a first volume of inflation fluid. The inflator assembly (20) further includes a second source (24) of inflation fluid which, when actuated, provides a second volume of inflation fluid which differs from the first volume. A position sensor (70) provides a position signal indicating a position of an occupant of the vehicle. A controller (50) actuates the first and second sources (22, 24) of inflation fluid in any one of a plurality of differing modes of operation in response to the collision signal and the position signal.

    摘要: An apparatus (20, 220) for inflating an inflatable vehicle occupant protection device comprises a first container (22, 222) defining a first chamber (24, 224) for inflation fluid. The first container (22, 222) has an opening (26, 226) through which inflation fluid may flow to inflate the protection device. A rupturable closure (28, 228) extends across the opening (26, 226) in the first container (22, 222) to block fluid flow through the opening. A second container (68, 268) defines a second chamber (70, 270). A plate (82, 282) is located between the first chamber (24, 224) and the second chamber (70, 270) and has a passage (84, 84a, 284 or 284a) which allows fluid communication between the first and second chambers. A rupturable membrane (86, 286) extends across the passage (84, 84a, 284, or 284a) in the plate (82, 282) to restrict fluid communication between the first chamber (24, 224) and the second chamber (70, 270) and has an orifice (100, 300) to allow limited fluid communication between the first and second chambers. Ignitable material (80, 280) is located in the second chamber (70, 270) and produces combustion products (P), upon ignition, which increase pressure in the second chamber to a predetermined pressure to rupture the membrane (86, 286) and open the passage (84, 84a, 284, 284a) in the plate (82, 282) for the combustion products to flow into the first chamber (24, 224) and effect heating of inflation fluid (F).
