Abstract
An occupant restraint system composed of a compact air cushion module containing a rotating vent ring which creates a variable venting system for inflation of an air cushion. The rotating vent ring moves to open one or more vents of different flow areas which allows inflation gas to vent to the atmosphere thereby controlling the pressure with which the inflatable air cushion fills. The rotating vent ring has a neutral or non-rotated position wherein the venting is minimized such that the inflatable air cushion fills with a maximum pressure. The rotating vent ring is rotated to a variety of positions in response to one or more changing environmental conditions within the vehicle. Such conditions may include occupant position, seat belt usage, occupant weight, ambient temperature or any other relevant environmental factor.
