<p>An automatically applied three point safety belt system includes a retractor reel located at one side of the vehicle seat and spring rewinding an inflatable tubular lap belt which is arcuate in its inflated state and a retractor reel located at the same side of the seat back above the occupant shoulder level and spring rewinding a shoulder belt having a rear inflatable tubular section which upon inflation, extends horizontally, forwardly of the occupant's shoulder. The ends of the belts are joined proximate an attached coupling ring which is lockable in engagement with a coupling hook on the other side of the seat. A flexible tube connects the interiors of the belts by way of a three way valve to a compressor, the valve being opened to connect the belt interiors to the compressor when the seat is occupied, and the vehicle door closed to inflate and extend the belts to advance the ring into engagement with the hook, and a manually, releasable locking member is actuated in response to such engagement, and the belts are deflated. A control network, including an inertia switch inflates the belts and locks the retractor reels under abnormal riding conditions, and recycles the application sequence when the ring is not engaged by the hook member.</p> |
