    • PROBLEM TO BE SOLVED: To provide a light weight and small sized gas generator capable of being simply and inexpensively manufactured without generating the problem of mutual ignition in a multistage gas generator. SOLUTION: The gas generator for an airbag module of an automobile has a plurality of separate generator stages which can be ignited independently of one another and each of which includes at least one igniter, at least one propellant charge and at least one combustion chamber in its own pressure housing. The generator stages are arranged at least partly in a common filter housing together with a common filter unit, and the space remaining in the filter housing is designed at least regionally as an-outflow passage system leading from outflow apertures formed in the pressure housing to the filter unit.

    • PROBLEM TO BE SOLVED: To provide a gas generator having an improved filtering function. SOLUTION: A housing 11 has an upper annular slant face 14 and a lower annular slant face 15, and a cylindrical filter 20 stored inside has an end face shape matching with the slant faces 14 and 15. When the housing 11 is axially expanded and deformed by the pressure in an operation, the slant faces 14 and 15 hardly deform and hence gas is prevented from leaking from an abutting section between the slant faces 14 and 15 and the cylindrical filter 20. Therefore, all gas is discharged through the cylindrical filter 20. COPYRIGHT: (C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a filter member for improving a bonding strength for holding parts of a wire forming meshes efficiently and at low cost. SOLUTION: In a wound filter 15 (filter member), which is to be installed in an inflater of an air-bag device, a gas, etc. of a very high temperature and pressure are passed through the meshes of the filter 15 at the time of actuation of the device. In order to prevent the bonding in the wire 16 from coming off in the actuation, a bonding strength of about at least 4N is required for the contact parts S of the wire 16. The filter 15 is manufactured on conditions satisfying the relation of 4≤C1×exp(-C2/T)×(t/T) 0.4 ×P×b 2 ×n, wherein T: heat-treatment temperature, t: time for heat treatment, P: contact surface pressure between wires 16, b: contact width between wires 16, n:number of contact parts between wires 16, C1 and C2 are respectively coefficients, and C1=4,105, and C2=9,000.
