Abstract

An airbag apparatus includes an airbag, an inflator, and an accumulator. The airbag is configured to be stored in a vehicle before inflation. The inflator is configured to provide gas for inflating the airbag. The accumulator is in fluid communication with the airbag and the inflator. The accumulator includes a chamber for at least temporarily storing gas after the inflator provides gas. The accumulator also includes a flow-control mechanism configured to permit gas to flow into the chamber at a first rate and to flow out of the chamber at a slower second rate.
