ABSTRACT:
A powered articulated headrest system for use with a seat structure having a backrest, such as the ejection seat of a high performance aircraft, e.g., a combat aircraft. The headrest system includes: a headrest assembly which is movably connected to the backrest; and, an electro-hydraulic actuator assembly for moving the headrest from an original (and normal) position above the backrest to any one of an infinite variety of positions which are rearward and downward of the headrest, and for moving the headrest from these other positions to the original position. The actuator assembly is controlled by the occupant of the seat, e.g., the pilot of the aircraft. When the headrest is moved rearwardly, unlike the prior art, the width of the headrest decreases thereby reducing any interference with aft visibility, and the height of the headrest also decreases thereby further reducing any interference with aft visibility and also eliminating any scrubbing action between the headrest and the head of the occupant of the seat.
