Abstract: An improved aircraft ejection seat system is described which embodies a forward leaning position for an occupant of the aircraft providing enhanced acceleration tolerance for an occupant during ejection from the cockpit, comprising a platform supporting at a rearward end thereof a seat having a seat back and seat pan sized and configured for accommodating the occupant, a forwardly disposed cowling integral with and faired to the platform for providing windblast protection to the occupant, a solid or cushioned upright wall member disposed centrally of the platform and extending between the seat and cowling and supporting an inclined chest plate for supporting the chest of the occupant in the forward leaning position, a head rest and a shield disposed near the upper end of the plate for shielding the occupant's head upon ejection from the aircraft, and a restraint harness for holding the occupant in the forward leaning position against the plate upon ejection from the aircraft.
