    摘要: An inflator assembly for inflating an inflatable vehicle occupant restraint includes a container defining a chamber with a rupturable wall. The chamber contains a first ignitable material and gas. The gas is directed from the container to the inflatable vehicle occupant restraint when the rupturable wall of the chamber is ruptured. The assembly further includes an initiator for rupturing the rupturable wall of the chamber and for igniting the first ignitable material inside the chamber. The initiator includes a second ignitable material. The second ignitable material produces a pressure wave and emits products of combustion when it is ignited by the initiator. The rupturable wall of the chamber is located in the path of the pressure wave and is ruptured by the pressure wave. The first ignitable material inside the chamber is located in the path of the products of combustion emitted by the second ignitable material and is ignited by the products of combustion.

    摘要: An apparatus for inflating an air bag (22) comprises a container (40) which holds an inflation fluid under pressure. The container (40) has an opening (44) through which the inflation fluid flows to inflate the air bag (22). A rupturable closure (80) is fixed to the container (40) and extends across the opening (44) to block the flow of inflation fluid through the opening when the closure is reinforced. The closure (80), when unreinforced, ruptures in response to pressure of the inflation fluid acting on the closure. A combustible member (100) is supported by the container (40) to reinforce the closure (80) and resist rupturing of the closure. The closure (80) becomes unreinforced upon a predetermined amount of combustion of the member (100). An actuatable initiator (120), upon actuation, initiates combustion of the member (100).

    摘要: An apparatus (24) for inflating an inflatable vehicle occupant protection device (22) comprises a container (40) which defines a chamber (42) for material which effects inflation of the protection device. The container (40) includes an opening (60) of a flow area through which fluid flows to inflate the protection device (22). A rupturable closure (64) blocks fluid flow through the opening (60) in the container (40). A first actuatable initiator (164), upon actuation, effects the rupture of the closure (64). A member (120) is movable from a first position in which the flow of fluid through the opening (60) is unrestricted when the closure (64) is ruptured. The member (120) is movable to a second position in which fluid flow through the opening (60) is restricted by a portion of the member to reduce the flow area of the opening. A second actuatable initiator (162), upon actuation, moves the member (120) from the first position to the second position and effects the rupture of the closure (64).

    摘要: A process for forming a grain (10) of gas generating material includes the step of forming pieces (86) of gas generating material, and further includes the step of forming the grain (10) as a compacted agglomeration of the pieces (86) of gas generating material. The pieces (86) of gas generating material are formed by pressing a particle mixture (60) under a first pressure. The grain (10) is formed by pressing the pieces (86) together under a second pressure which is less than the first pressure.

    摘要: An apparatus for protecting a vehicle occupant comprises an Air bag having a stored deflated condition and an inflated condition for protecting a vehicle occupant. The apparatus also comprises an actuatable inflator (20, 320) for, when actuated, directing inflation fluid into the air bag. An energizable initiator (28, 228, 328) actuates the inflator (20, 320) upon energization. The initiator (28, 228, 328) comprises a foil, bridge section (126) and a flyer section (142). The foil bridge section (126) heats and explodes, in response to energization of the initiator (28, 228, 328), to propel the flyer section (142) to actuate the inflator (20, 320).

Fluid is in the chamber (62) and comprises a combustible fuel gas. The container (60) includes an inner housing (64) comprising an inner member (80) extending along an axis (A). The inner member (80) has a first surface portion defining the chamber (62). A second surface portion (180) of the inner member 80 defines at least a portion of the periphery of the inner member (80) extending along the axis (A). An outer housing (66) comprises an outer member (84) with a third surface portion (182) engaging and supporting the second surface portion (180) of the inner member (40) over its axial and circumferential extent. An igniter (100) ignites the fuel gas to create heat. An opening (220) in the outer housing (66) directs gas from the chamber (62) to inflate the protection device (22).

    摘要: An air bag inflator (20) includes gas stored at or above a predetermined pressure in a chamber (24) in a container (22). An initiator (10) connected with the container (22) is exposed to the pressure of the gas stored in the chamber (24). A closure can (120) of the initiator (10) includes an electrically conductive sensor portion (140) which is spaced apart from an electrically conductive contact can (200) when the pressure in the chamber (24) is at or above the predetermined pressure. If the pressure in the chamber (24) drops below the predetermined pressure, the sensor portion (140) moves into electrical contact with the contact can (200). The engagement of the sensor portion (140) with the contact can (200) completes an electrical circuit to provide an indication of low pressure in the inflator (20).
