Abstract

A gas generator comprising the following parts: a cylindrical cover (3) composed of an initiation shell (1) and a closing shell (2) with a plurality of ignition devices (16, 17); formed on the cover ( 3) and a combustion chamber filled with gas generating agents (14a, 14b); a cylindrical member that divides the above combustion chamber into two or more combustion chambers (4, 7); The filter device (6, 8) in each combustion chamber (4, 7) above the chamber is characterized in that at least one of the above-mentioned filter devices (6, 8) is disc-shaped, and each of the above-mentioned combustion chambers (4, 7 ) are independent of each other.

Description

technical field [0001] The present invention relates to a gas generator for a condition-adaptive airbag which uses a plurality of igniters to burn a gas generating agent in a cover and to control the inflation and deployment of the airbag. Background technique [0002] In order to protect occupants from the impact of a car collision, the gas generator that rapidly inflates and deploys the airbag is assembled in the airbag module, which is installed in the steering wheel or the instrument panel. The gas generator operates the igniter (detonator) according to the electric signal from the control device (actuator), and uses the flame of the igniter to burn the gas generating agent to generate a large amount of gas rapidly. [0003] The gas generator of the prior art often inflates and deploys the airbag rapidly regardless of the occupant's seating posture (regular seating, irregular seating such as forward bending) and vehicle speed (acceleration) at the time of collision. The...
