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). 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). 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： 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 airbag module providing adaptive performance. The module includes a housing defining an interior. At least an inflator is received within the housing, and preferably the folded, uninflated cushion, also. Various arrangements are provided to selectively block, or create, a vent extending through the housing. This vent, when open, permits the inflation gas provided by the inflator to exit the housing without entering the cushion. The vent may be initially open, and blocked by a sliding cover block, may be initially closed and opened by movement of a slide plug, or may be initially closed and opened by deformation of a portion of the housing. The venting of the inflation gas will at least slow the rate of inflation of the cushion, and may reduce the final pressure within the cushion. As such, the housing will be vented for less severe collisions, and will not be vented for more severe collisions.

摘要： An airbag inflator with venturi effect cooling and gas supplement. The inflator includes a housing having a quantity of gas-producing fuel therein, and possibly a stored gas also, along with appropriate igniters. These materials are stored within a gas production chamber of the housing. The gas leaving this chamber travels through the housing to an exit port on the housing. Intermediate the gas production chamber and the housing exit port is a venturi section of the housing. This section reduces the pressure of the gas, and thus the pressure at the interior end of draw vents opening onto the venturi section. The vents therefore draw outside air into the housing to mix with the gas. This cools the gas to the desired temperature, and also supplements the gas exiting the housing. As such, the need for a heat sink to cool the gas is reduced or eliminated. Furthermore, since the cushion is inflated with a mixture of gas and air, the amount of gas typically needed is reduced by the amount of added air. This permits the amount of fuel to be reduced, thus reducing cost and weight.

摘要： An inflator of a vehicle safety restraint system includes a housing having a reservoir of liquid propellant. A combustion chamber is disposed in the housing in communication with the liquid propellant reservoir. A regenerative piston is movably disposed within the housing for separating the liquid propellant reservoir and the combustion chamber. The piston head includes a plurality of injection ports for delivering the liquid propellant to the combustion chamber in a controlled manner. A pressure relieving bore, normally sealed by the piston stem, is disposed in the housing for relieving pressure in the liquid propellant reservoir. Decomposition or combustion within the propellant storage reservoir will move the piston to open the pressure relief bore which depressurizes the liquid propellant and prevents rupture and fragmentation of the inflator.
