Abstract: 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 chambers 30, 50 are separated by a partition wall 35. The partition wall 35 is fixed by discontinuous protrusions 61, 62 formed in a housing 11. Air tightness between two combustion chambers 30, 50 is ensured by two retainers 80, 90.

Abstract: The invention is a gas generator, including: a tubular housing having a gas discharge port, a combustion chamber provided inside the tubular housing and charged with a solid gas generating agent and a flame transmission tube disposed in an axial direction of the tubular housing inside the combustion chamber and provided with a plurality of communication holes that communicate with the combustion chamber, the flame transmission tube having an ignition region provided with an ignition device and a flame transmission region for transmitting flame generated by the actuation of the ignition device, the ignition region and the flame transmission region meeting the following requirements (a) and (b): (a) a mean inner diameter of the ignition region>a mean inner diameter of the flame transmission region; (b) a total opening surface area of the communication holes in the ignition region<a total opening surface area of the communication holes in the flame transmission region.

Abstract: 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.

Abstract: 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.

Abstract: A hybrid inflator has flame-transferring holes 118 which allow outflow of a booster gas, and first communication holes 125 which 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.

Abstract: A multistage inflating-type hybrid inflator in which a malfunction does not occur is provided. When a first gas generating chamber 130 is first burnt, a combustion gas flowed out of first communication holes 136 advances in a direction towards an inner wall of an inflator housing 102 but it does not flow in a direction towards a second gas generating chamber 140. For this reason, the malfunction of the second gas generating chamber 140 cannot occur due to heat energy of the combustion gas.

Abstract: The present invention provides a gas generator for an air bag which can ensure a reliability of operation start sufficiently and in which an operation performance as designed can be obtained securely without adding further members.

Abstract: The present invention provides a hybrid inflator without malfunctioning.

Abstract: The Abstract of the Disclosure has been amended as follows:

Abstract: 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.
