ABSTRACT:
An inflator for a safety restraint system includes a gas storage vessel having a mouth, and a diffuser extending outwardly from the mouth and defining gas outlet ports. A combustion chamber having a flared open end is secured to the gas storage vessel peripherally adjacent the mouth and defines throttle orifices for releasing inflation gas from the gas storage vessel. A breakaway closure member is secured across the mouth of the gas storage vessel and the open end of the combustion chamber housing, the breakaway closure member including a periphery ring, a translating boss having an initiator mounted therethrough and a skirt slidingly received in the open end of the combustion chamber housing, and a frangible web connecting the boss to the periphery ring. The combustion chamber housing further defines exhaust ports opening to the gas storage vessel, and contains combustible material, which may be pyrotechnic gas generator or fluid fuel. The initiator ignites the combustible material and the resultant increased pressure in the combustion chamber housing fractures the frangible web and drives the translating boss into the diffuser to release gas from the gas storage vessel through the throttle orifices and diffuser. Hot products of combustion are delivered through the combustion chamber exhaust ports to heat and augment the pressure of the gas.
