The present invention relates to a side curtain air bag safety device that protects a vehicle occupant from expansion of the air bag when the occupant is not in a desired position in the vehicle. The air bag includes an internal tether that is connected to a valve at the end of a throat liner within the bag. When the air bag expands and when the occupant is in a desired position, the tether extends fully and triggers the valve such that inflation gas is directed in a usual direction providing cushioning adjacent to the occupant. However, when the occupant is not in a desired position the tether cannot fully extend and as a result the expansion gas is directed in an alternate direction that does not apply as much force within the bag in an area near the occupant, thus preventing injury.
