Abstract
The present invention provides a gas generator for expanding and inflating a driver's seat airbag. The gas generator comprises two ignitor device 8, 9 for burning gas generants 7 packed in combustion chambers 3, 4, and enhancer device 10, 11 for allowing the flames from the ignitor device 8, 9 to be propagated circumferentially and radially of a housing 1.
Claims10
A gas generator, comprising:
- a cylindrical housing;
- gas generants packed in the housing to generate gas by combustion;
- a plurality of ignitor devices for spouting flames into the housing to burn the gas generants packed in the housing, at least one of the ignitor devices is eccentrically disposed with respect to an axis of the housing;
- and
- the enhancer devices for allowing the flame of the ignitor device disposed on the eccentric position to be propagated circumferentially and radially of the housing.
