Gas generator for restraining apparatus

摘要

The invention provides a gas generator for a restraining apparatus, including:
a housing an ignition device, and a gas generating agent accommodated in the housing, anda cup-shaped container having a flame-transferring hole in a circumferential wall and being disposed on a tubular igniter-fixing portion of the housing to form an ignition device chamber accommodating the ignition device,the cup-shaped container having a plurality of protruding portions protruding inward in the radial direction from the circumferential wall portion,the tubular igniter-fixing portion having a recess on an outer surface,at least a distal end portion of the protruding portion engaging with an inner wall surface of the recess to block an axial movement of the cup-shaped container.

主权项

1. A gas generator for a restraining apparatus, comprising:
a housing having a gas discharge port and formed by a closure shell and a diffuser shell; an ignition device, which includes an igniter, and a gas generating agent being accommodated in the housing; and a cup-shaped container having a flame-transferring hole in a circumferential wall portion thereof and being disposed on the closure shell inside the housing to form an ignition device chamber, the ignition device chamber accommodating the ignition device, and the igniter being fixed to a tubular igniter-fixing portion provided in the closure shell, the cup-shaped container having a plurality of protruding portions protruding inward in a radial direction from the circumferential wall portion thereof, the tubular igniter-fixing portion having a recess on an outer surface, at least a distal end portion of each of the plurality of protruding portions of the cup-shaped container abutting on an inner wall surface of the recess of the tubular igniter-fixing portion to block an axial movement of the cup-shaped container.
