ABSTRACT:
An occupant restraint system for a vehicle including an air bag having a collapsed inoperative condition and an expanded operative condition for restraining movement of an occupant of the vehicle during a collision, a fluid supply, and a diffuser for directing fluid from the fluid supply into the air bag. The fluid supply includes a staged source of fluid for expanding the air bag. Fluid from the first source stage is introduced into the diffuser immediately upon the collision of the vehicle to initiate expansion of the air bag. After a time delay of milliseconds, a greater mass flow of fluid from the second source stage is introduced into the diffuser to complete the expansion of the air bag.
