Abstract: A gas generator includes a shortened cylindrical housing constituted by a lower lid that is an initiator shell including an ignitor device, and an upper lid which is a closure shell for closing the lower lid. Additionally, in the housing, an ignitor device, gas generants, and a filter material are arranged in this order from the center. The ignitor device includes an igniting agent filled container including an igniter and igniting agents therein, and a cylinder body provided in a state adhered to an outside surface of the igniting agent filled container. The gas generator is capable of stabilizing an ignition performance by a simple constitution.

Abstract: A gas generator includes a cylindrical housing having an initiator shell provided with a plurality of igniter devices and a closure shell; a combustion chamber formed in the housing and loaded with gas generants; a cylindrical member that partitions the combustion chamber into two or more combustion chambers; and filter elements provided in the respective combustion chambers of the partitioned chamber wherein at least one of the filter elements is disk-shaped, and the respective combustion chambers are independent from each other.

Abstract: A gas generator comprises: a cylindrical housing (3) comprising an initiator shell (1) provided with a plurality of igniter devices (16, 17) and a closure shell (2); a combustion chamber formed in said housing (3) and loaded with gas generants (14a, 14b); a cylindrical member that partitions said combustion chamber into two or more combustion chambers (4, 7); and filter elements (6, 8) provided in the respective combustion chambers (4, 7) of the partitioned chamber wherein at least one of said filter elements (6, 8) is disk-shaped, and said respective combustion chambers (4, 7) are independent from each other.

Abstract: In a gas generator comprising a cylindrical housing 1, gas generants 16 for generating gas by burning, which are charged in a plurality of combustion chambers 41 and 42 divided within the housing 1 and provided with orifices, and a plurality of ignitor devices 4 and 5 for burning the gas generants 16 within the respective combustion chambers 41 and 42 by spouting flame into the respective combustion chambers 41 and 42, wherein the ignitor devices 4 and 5 are arranged at each eccentric position from an axis of the housing 1, an enclosed space A for staying the generated gas discharged from the respective orifices 12 and 13 is formed at an outlet portion of the respective orifices 12 and 13 in the combustion chambers 41 and 42 having the ignitor devices arranged at the eccentric positions, and after passing through the enclosed space A, the gas is discharged from a gas discharge hole 14 formed in the housing 1.
