    摘要: A pressurized gas inflator suited for side impact airbags comprises an elongated cylindrical bottle having a closed end and an open end defining an outlet opening. A diaphragm is sealed across the open end of the bottle to form a chamber containing pressurized gas. A cup-shaped diffuser also has an open end secured to the open end of the bottle with the periphery of the diaphragm therebetween. A squib is mounted in the diffuser for rupturing the diaphragm. An enhanced squib with 300-400 milligrams of ZPP is used in one disclosed inflator and an augmented directional initiator is used in another disclosed inflator. The enhanced squib and augmented directional initiator provide heating to offset adiabatic cooling of the gas. The diffuser defines outlet ports for delivering the inflation gas. The cylindrical bottle has a mounting flange on its closed end, and the mounting flange may be an end cap with a radially extending flange. The diameter of the bottle may be necked down at the open end defining the outlet opening. The squib may be mounted through the wall of the diffuser, with the squib terminals exposed for plug connection.

    摘要: A heat-enhanced boosted inflator for a vehicle airbag includes a housing defining a storage chamber having compressed inflation gas therein and a heating cup mounted to the housing and defining a portion of a gas delivery path to the airbag. The heating cup contains a heat-producing material and the gas flows through the heat-producing material to heat-expand it. One heat-producing material is thermite (Al+FeO.sub.3) and ignitor means initiate its reaction. A cylindrical heating cup provides an annular heating chamber containing the heat-producing material and further defines an outlet plenum containing inflation gas which is released initially for a "soft" onset of inflation.

    摘要: A hybrid inflator for an inflatable restraint system has a center frame and two tubular end caps forming an elongated housing defining a chamber storing pressurized inert gas. Unit means for heating and delivering the stored gas are mounted in the center frame and positioned to deliver inflation gasses centrally with respect to the elongated housing. In a two unit embodiment, one unit includes a squib and a pyrotechnic gas generant, and the other unit defines an outlet orifice and baffle plate. In another two unit embodiment, the second unit includes an essentially non gas-producing heating composition which, when activated, heats and expands the pressurized gas. In a third embodiment, a unit includes heating material and ignition means and defines the outlet orifice. The center manifold is extruded metal stock with two opposing flat surfaces adapted to mount one or more units.

    摘要: An initiator suitable for use with airbag passive restraint systems and which does not use pyrotechnic materials is disclosed. The initiator provides an electrically actuated igniter which ignites an adjacently stored non-pyrotechnic fluid combustible material which may comprise a mixture of a fluid fuel and a fluid oxidizer, a fluid monopropellant or a fluid exothermically decomposable material. A sub-assembly of the non-pyrotechnic initiator with a fuel containment chamber and inflators which use the non-pyrotechnic initiator are also disclosed.
