Abstract
A hybrid inflator device for a passive restraint air bag system includes a housing defining a first chamber and a baffle passing through the first chamber. A supply of gas generant material is disposed in the first chamber and surrounds the baffle. An initiator is operative for creating a shock wave to open a burst disk and further operative to generate a hot gas to ignite the gas generant material. The initiator is disposed proximate a first end of the baffle. The baffle includes a reduced inner diameter portion and an unobstructed path extending along the length of the baffle.
