Abstract
Abstract A passive inflatable restraining system for a vehicle including a concealed inflatable bag stored in the roof and B-pillar of the vehicle when in the inoperative condition and having one end attached at a central portion of the vehicle and having a second end attached to the B-pillar of the vehicle and further including a sealed tube from the inflatable bag to an inflator concealed at the top of the B-pillar. Upon impact determined by a sensor, the inflator discharges compressed gas through the tube to the inflatable bag which discharges the bag from its concealed portion as it is inflated and projects the inflatable bag over the occupant's head and across his torso in the direction of the dashboard of the vehicle.
