ABSTRACT:
A lateral head restraint system providing support to a pilot's head during ejection or high-acceleration flight maneuvers. The lateral head restraint system includes inflating bladders positioned on opposite sides of a pilot's head. The bladders inflate from a compressed wedge position, sweeping through an arc on each side of the headrest structure. Inflation of the bladders centers the pilot's head into the correct control position and restricts lateral movement. When fully inflated, the bladders permit the pilot to lean forward or turn his head to either side. Further, an unobstructed field of vision is provided. The lateral head restraint system is incorporated into the ejection seat and remains fully operational during the ejection procedure to protect the pilot's head from injury.
