Abstract
An adaptive valve for an airbag inflator having a manifold with an exhaust opening for fluid communication with an airbag. The adaptive valve is constructed for connection to a manifold so that it is in fluid communication therewith. The adaptive valve has an exhaust orifice and is constructed to selectively open the exhaust orifice to divert inflation gas away from an inflator manifold when it is connected thereto to lower the rate of inflation of an airbag in fluid communication with the exhaust opening of the manifold. The adaptive valve may have a valve member movably mounted therein for movement between a first position wherein it closes the exhaust orifice and a second position wherein it opens the exhaust orifice. An initiator is provided in the adaptive valve to generate sufficient gas pressure to move the valve member to the first or second position.
