A method of manufacturing a filter for a gas generator, by which a filter having a good shape retaining property can be obtained, is provided. A method of manufacturing a filter for a gas generator in which a tubular material is formed by knitting copper-plated iron wires, molten plated copper is adhered to an intersecting portion of the iron wire to fix the intersecting portion, wherein the method comprises a molding step for producing a tubular material by knitting the copper-plated iron wires, and a heat processing step in which the above tubular material is kept at a temperature not less than a melting point of copper but less than the temperature of sintering of the iron, and is then cooled.

Filter for gas generator

A gas generator that can prevent erroneous operation in which the combustion of a gas generating agent inside one combustion chamber is caused by the combustion of a gas generating agent in the other combustion chamber. Two combustion chambersare separated by a partition wall. The partition wallis fixed by discontinuous protrusionsformed in a housing. Air tightness between two combustion chambersis ensured by two retainers

Gas generator

A hybrid inflator in which a weight thereof and the number of manufacturing steps can be reduced is provided. First and second communication holes 125 and 135 by which first and second gas generating chambers 120 and 130 communicates with an inflator housing 102 are formed in a gas generator housing 105. Therefore, no screen is required and thus, the weight and the number of manufacturing steps can be reduced.

Hybrid inflator

A gas generator for an air bag, which can ensure a reliable activation and an operation performance as designed without adding further members. The gas generator includes a moving body for rupturing a first rupturable plate that closes a first opening provided between a first gas generating chamber and a pressurized medium accommodating chamber, and a second opening and a second rupturable plate for closing the second opening provided at a position deviated from a hitting portion of the moving body rupturing the first rupturable plate.

Gas generator for air bag

A hybrid inflator has flame-transferring holeswhich allow outflow of a booster gas, and first communication holeswhich allow outflow of a combustion gas are arranged in the same position in the longitudinal direction of the hybrid inflator to render smooth outflow of the booster gas and the combustion gas.

A multistage inflating-type hybrid inflator in which a malfunction does not occur is provided. When a first gas generating chamberis first burnt, a combustion gas flowed out of first communication holesadvances in a direction towards an inner wall of an inflator housingbut it does not flow in a direction towards a second gas generating chamber. For this reason, the malfunction of the second gas generating chambercannot occur due to heat energy of the combustion gas.

Multistage inflating-type hybrid inflator

An inflator comprises a cylindrical inflator housing elongated in an axial direction and containing a gas generating material for inflating an air bag, and an activation assembly for generating an activation gas for activating the gas generating material. A cylindrical diffuser assembly is provided in an axial end of the inflator housing. The diffuser assembly has an end surface, and also has a plurality of outlet holes in a peripheral wall surface thereof. A through-hole is formed in the end surface of the diffuser assembly, and a stud bolt for fixing the inflator is inserted into the through-hole. The stud bolt is fixed by a flange portion provided on an end portion thereof.

Inflator

A hybrid inflator in which a weight thereof and the number of manufacturing steps can be reduced is provided. First and second communication holes and by which first and second gas generating chambers and communicate with an inflator housing are formed in a gas generator housing . Therefore, no screen is required and thus, the weight and the number of manufacturing steps can be reduced.
