Abstract: A gas generator (1A) comprising: an ignition chamber (13) in which an igniter (12) and an enhancer agent (14) stored therein; a first combustion chamber (23) and a second combustion chamber (33) in which gas generating agent (24, 34) stored therein respectively; a first transfer path (15) communicating the ignition chamber (13) with the first combustion chamber (23); and a second transfer path (16) communicating the ignition chamber (13) with the second combustion chamber (33). The first transfer path (15) and second transfer path (16) are disposed to be displaced in parallel such that a center line (15a) of the first transfer path (15) and a center line (16a) of the second transfer path (16) do not overlap on the same straight line. Because of such a configuration, in a gas generator having two or more gas output portions driven by one igniter, it becomes possible that an effect of combustion of a gas generating agent in each combustion chamber is substantially or completely independent.

Abstract: A gas generator including an approximately cylindrical housing including an ignition chamber, first and second combustion chambers, and first and second discharge paths. The ignition chamber, disposed in a base portion of the housing, includes an igniter and an enhancer agent. The first and second combustion chambers, disposed respectively in first and second cylindrical portions of the housing, each contains gas generating agent. The first and second discharge paths are disposed respectively on front end sides of the first and second cylindrical portions of the housing and enable gases generated in the first and second combustion chambers to be discharged from the housing therethrough. The inner diameters of the first and second combustion chambers are regulated to differ from each other. Thereby, outputs in respective gas output portions can be made to differ, while size increase and slower start-up of gas output in each gas output portion are prevented.

Abstract: A gas generator is provided with a metal housing constituted by an initiator shell and a closure shell, a combustion chamber which is formed inside the housing and into which gas generants generating a high-temperature gas through combustion are loaded, a filter member disposed around the combustion chamber, an igniter mounted into the housing and igniting and burning the gas generants inside the combustion chamber and a plurality of gas discharge openings formed on the housing and discharging the gas generated in the combustion chamber.

Abstract: A gas generator (30) is provided with a metal housing (3) constituted by an initiator shell (1) and a closure shell (2), a combustion chamber (5) which is formed inside the housing (3) and into which gas generants (4) generating a high-temperature gas through combustion are loaded, a filter member (6) disposed around the combustion chamber (5), an igniter (7) mounted into the housing (3) and igniting and burning the gas generants (4) inside the combustion chamber (5) and a plurality of gas discharge openings (8a, 8b) formed on the housing (3) and discharging the gas generated in the combustion chamber (5), and in which either or both of the initiator shell (1) and the closure shell (2) constituting the housing (3) are provided with semi-spherical or semi-oval end plate portions (14, 10) and cylindrical portions (13, 9) having a diameter D formed continuously from these end plate portions (14, 10), H/D or a ratio of the bottom distance H between the end plate portion (14) of the initiator shell (1) and that (
