Abstract: An air bag module with adjustable cushion inflation is provided by including a valve member in the module which is movable to change the size of an inflation outlet through which inflation fluid flows into an air cushion while simultaneously changing the size of a vent outlet which enables inflation fluid to be vented to the ambient atmosphere. The valve member is positioned by a control unit which receives input from various sensors within the vehicle regarding such factors as ambient temperature, occupant position, occupant weight, seat belt usage, etc to produce an optimum cushion inflation based upon these factors.
