Abstract:
A method of discharging combustion gas from an airbag inflator including a housing, a central cylinder member provided within said housing and having a plurality of through-holes, and a coolant/filter device for at least one of cooling and filtering a combustion gas, comprising:generating flames by ignition of an ignition device provided within an inflator housing and passing the flames through the plurality of through-holes; deflecting the flames by a flame-resisting plate within a combustion chamber for covering an only portion of said coolant/filter device, where the flames from the through-holes would make contact with said coolant/filter device; generating a combustion gas by a combustion of a gas generating material ignited by the flames deflected by the flame-resisting plate inside an airbag inflator housing having gas-discharge ports; cooling and filtering the combustion gas by a coolant/filter device defining the combustion chamber, wherein said flame-resisting plate protects an inner circumferential surface of said coolant/filter device from being damaged by the flames passing through the through-holes.
