摘要： A hybrid inflator (10) for a vehicle passenger restraint system comprises a centre tie (14) having upper and lower ends (16, 18), and a curved, continuous vessel wall (20) secured to the upper and lower ends of and surrounding the centre tie to define a pressure chamber (26) storing inert compressed gas. The centre tie defines a combustion chamber (30) extending from the lower end thereof, the combustion chamber receiving pyrotechnic gaseous heat source material (31) and a squib (32) for igniting it. The centre tie further defines a directional inlet port (40) extending from the combustion chamber into the pressure chamber and a rupturable diaphragm (44) seals the inlet port until ignition of the pyrotechnic generant. The centre tie also defines a directional outlet vent (50) extending from the pressure chamber adjacent the upper end of the centre tie, the directional outlet vent being oriented substantially opposed the inlet port. The outlet vent is part of an outlet passage (53) from the pressure chamber through the upper end of the centre tie, including an orifice cavity (52) and outlet orifice (54), oriented to provide further turns in the gas flow path. A rupturable diaphragm (58) seals the outlet passage until ignition of the gas generant. A diffuser (62) provides an additional change of direction of the outlet path.

摘要： A heat-enhanced inflator (10) for vehicle airbag inflation includes a housing (12) with a cylindrical sidewall (22) enclosing a gas storage chamber (30) and a heating cup (14) containing heat producing material (15). The heating cup has concentric inner (26) and outer (24) walls between which longitudinal passages (52) in the heat producing material (15) constitute gas delivery passages. When a squib (56) ignites igniter material (58) and rapid deflagration cord (60) the heat producing material is actuated and a diaphragm (42) in the heating cup ruptures to allow pressurized gas to pass through the heating cup (14) via openings (36, 38, 16). The heating cup may be centrally located in an elongate housing and may be confronted by ignition means arranged to directly rupture the diaphragm to allow gas into the heating cup. Such rupture may be assisted by a projectile.

摘要： A process for converting sheet stock into a seamless outer shell for a toroidal shaped hybrid inflator for air bag inflation systems. In the process a seamless toroidal shaped shell is fabricated from sheet stock by a sequence of process steps comprising first drawing the sheet into a cup shaped blank (12) with curved transitions (18) between the bottom wall (14) and the sidewall (16) and then shaping the open end (20) of the cup to the desired toroidal shape while simultaneously thickening the areas adjacent to the perimeter of the open end of the cup and finally removing the central portion of the bottom of the cup, thereby producing the desired shell.

摘要： The inflator comprises an upper stamped metal housing part (24) welded (36) to a lower stamped metal housing part (26) which includes an integral centre tie (22) containing a metal cup (42) accommodating gas generant material (70) and an igniter assembly (43) including a squib (64). Initiation of the generant material (70) causes an upper piston portion of the cup (42) to separate from the rest of the cup at a circumferential groove (52) and move upwardly uncovering openings (55) which allows hot gas to pass outwardly into a surrounding toroidal chamber (20) accommodating pressurised gas from where gas passes inwardly through further openings (58) into the centre tie (22) above the cup (42) and then out of the inflator through a frangibly sealed orifice (40). Upward movement of the piston portion is arrested by friction and inwardly directed tabs (60).

摘要： A low cost inflator (10) is disclosed having a thin-walled hermetic liner (14), filled with either a stored gas or a flammable fluid mixture (56), and having a minimal number of joints required for sealing. Structural support is provided by parts that are not required to be hermetic. To activate the inflator, a small amount of pyrotechnic material (58) is used to move a piston (16), crushing the thin-walled liner and compressing the stored inert gas, or alternatively compressing and igniting the stored flammable fluid mixture, causing the gas to escape into the air bag. Optionally, the stored inert gas or flammable fluid mixture can be augmented by hot gases produced by the pyrotechnic material. The piston-driving material may be composed of a wide variety of pyrotechnic materials, combustible mixtures of fluid fuels and oxidants, or compatible combinations of both. The inflator design incorporating a stored combustible fluid mixture will, upon ignition of the mixture, produce a heated gas able to more quickly inflate the air bag, as compared to a cold gas or blow down system of the same size and pressure. The combustible fluid mixture is selected so that while production of undesirable incomplete products of combustion and particulate matter are minimized, the fluid mixture must be compressed to ignite, thereby eliminating storage and handling issues problematic to some inflators featuring combustible fluid mixtures.
