초록

A dual-stage gas bag inflator, operable initially, when activated, to cause the gas bag to deploy slowly and then, after a delay, to deploy rapidly, includes a housing having first and second compartments of different size separated by a bulkhead. The first compartment is the smaller since it is to produce a smaller amount of gas to cause the initial slow deployment of the gas bag. A gas generant charge is ignited in the first compartment, and after some delay, a gas generant charge in the second compartment is ignited. The delay is produced by an initia...
