Abstract
A new type of airbag inflator is described. The airbag inflator includes a chamber that houses a quantity of inflation gas. The inflation gas is capable of filling and deploying an airbag. The inflator also includes a membrane that seals the chamber. A sliding baffle is also added to the inflator. The sliding baffle is positioned proximate the membrane. The sliding baffle has a membrane rupture mechanism and a plurality of gas flow holes. Upon initiation of the inflator, the sliding baffle slides to cause the rupture mechanism to fail the membrane. The rupture mechanism fails the membrane by detaching a single piece from the membrane. The single piece is sufficiently large such that it remains within the inflator (or within the sliding baffle) and does not pass through one of the gas flow holes.
