ABSTRACT:
A head restraint system is disclosed that is designed to protect the pilot's head against severe lateral forces. A circular track surrounds and is affixed to the pilot's helmet. The track is attached by two cables to a seat back. During normal flight conditions, the cables provide a small but constant tension to the helmet, and allow the pilot's head free movement in all directions. A spring loaded inertia reel will lock the cables in place when the lateral forces exceed a predetermined level. The system will also provide afterward head support during the pilot's emergency ejection from the aircraft, and the cables are automatically severed when the pilot is separated from the seat.
