摘要： Multiple bridgewires are distributed through the length of the elongated tubular igniter of an automotive vehicle passenger side inflator. Upon receipt of an electrical stimulus the bridgewires ignite sensitive booster charges which ignite ignition powder within the igniter tube at the multiple distributed bridgewire locations. The use of this system eliminates the need for high velocity pyrotechnics in the ignition system to ignite the inflator gas generant within acceptable time constraints when the tubular igniter is ignited from one end by an initiator, and replaces the squib initiator.

摘要： An inflator of a vehicle safety restraint system having a flow inhibitor system which forces ignition gases through a gas generant of the inflator. A housing includes a gas generant chamber and an igniter for generating an ignition gas. A gas generant is disposed within the gas generant chamber for generating an inflation gas. A shock absorbing devive supports the gas generant in the housing. The shock absorber is disposed within a region of the gas generant chamber. A flow inhibitor blocks the flow of the ignition gas into the region of the shock absorber. The flow inhibitor is disposed adjacent the shock absorber, such that the ignition gas does not enter the region of the shock absorber but passes solely through the gas generant.

摘要： A passenger air bag inflator using pressurized inert gas upon initial deployment to provide cool gas to the folded air bag. After the bag has started to unfold, the remaining gas is provided by pyrotechnic gas generant. Pyrotechnic gas expands against a piston. The piston compresses the inert gas and forces it to exhaust from the inflator. Upon expulsion of the inert gas, the piston then becomes a filter for the pyrotechnic. The system provides a reduction in air bag stresses from fast hot gas deployments.

摘要： 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).

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). A second pyrotechnic charge (124) in the second chamber (114) has a second burn rate less than the first burn rate. The housing (82) has second fluid outlets (98) for enabling flow of combustion products from the second chamber (114) to the gas storage chamber (14).

摘要： An inflator (10) for providing inflation fluid to inflate an inflatable vehicle occupant protection device includes a pressure vessel (12) defining a chamber (30) for inflation fluid. The pressure vessel (12) has a passage (40) through which inflation fluid flows from the chamber (30). A burst disk (52) blocks fluid flow through the passage (40). A member (80) is disposed adjacent to and on one side of the burst disk (52) prior to the inflation fluid entering the pressure vessel (12). The burst disk (52) deforms toward the one side due to the pressure of the inflation fluid when the inflation fluid is disposed in the chamber (30). The member (80) limits deformation of the burst disk (52) by contacting the burst disk. An actuatable igniter assembly (66), when actuated, moves the member toward the burst disk (52) to rupture the burst disk and enable the inflation fluid to flow from the chamber (30) through the passage (40).

摘要： A regenerative monopropellant inflator having improved initiation of the regenerative cycle and improve operating efficiency. The inflator may direct the flow of the monopropellant into a localized volume to create a "hot spot" to increase combustion. This serves to ensure that the regenerative cycle is initiated. Various arrangements are provided to increase the residence time of the combusting monopropellant within the inflator, to ensure complete combustion of the monopropellant, and thus increased efficiency. These arrangements include inducing a helical gas flow to increase the length of the path traveled by the gas. Various barriers may also be placed within the gas flow to force direction changes, which reduce the velocity of the gas.

摘要： A regenerative liquid propellant rocket motor including a body having an integrally formed central tube. A primary combustion chamber is disposed in the body. A secondary combustion chamber is formed by the central tube of the body. A reservoir of liquid propellant is disposed in the body. A regenerative piston is slidably disposed in the body for delivering the liquid propellant to the primary and secondary combustion chambers. The piston includes a plurality of injection ports for injecting the liquid propellant. An ignitor is disposed in the body for initiating combustion of the liquid propellant. A nozzle is formed at a free end of the central tube for producing thrust, wherein upon ignition of the ignitor combustion occurs in the primary combustion chamber driving the piston into the liquid propellant reservoir and the liquid propellant is injected into the primary combustion chamber to produce combustion products which are channeled into the secondary combustion chamber and expanded through the nozzle.
