Abstract: An apparatus for supporting the head of a crew member sitting in a forward posture in a vehicle during high "G" accelerations is disclosed. The invention comprises an upper torso assembly secured to the crew member's upper torso and a head support member. The head support member is hingedly connected to the upper torso assembly for preventing the crew member's head from rotating forward when sitting in a forward lean posture during high G accelerations. The apparatus thereby maintains the proper head position for viewing aircraft displays and viewing the vehicle's external environment. The head support member further allows for free head mobility when the crew member is in the normal upright sitting position.
