Inflator
First Claim
1. An inflator for supplying gas into an airbag mounted on a motor vehicle and deploying the airbag, comprising:
- a first chamber having a gas blowing-outlet and containing an initiator and a gas-generating agent generating the gas by being ignited by the initiator;
a filter for covering the gas blowing-outlet of the first chamber, said filter absorbing heat of combustion of the gas-generating agent, and capturing a residue of the gas-generating agent;
a second chamber attached to the first chamber and containing compressed gas therein; and
a flow amount control member partitioning the first and second chambers, said flow amount control member being ruptured by gas of the gas-generating agent so that the compressed gas is ejected after the gas from the gas-generating agent is ejected.

Abstract
An inflator supplies gas into an airbag mounted on a motor vehicle and deploys the airbag. The inflator includes a first chamber wherein a gas blowing-outlet is provided and a gas-generating agent generating the gas by being ignited by an initiator is encapsulated. A filter is interposed between the gas blowing-outlet of the first chamber and the gas-generating agent. A second chamber is attached to the first chamber with a flow amount control member interposed therebetween, wherein compressed gas is encapsulated. A blocking member blocks a control hole of the flow amount control member so that the control hole is opened by being ruptured or removed by expanding pressure of the gas-generating agent.
