Abstract
A G-protective ejection seat assembly for an occupant of the cockpit of an aircraft. The assembly includes a cradle having a rigid, non-articulated upper portion and a rigid lower portion pivotally attached to the upper portion. The upper portion is pivotally attached to the aircraft for selected angular movement within the cockpit between an upright position and a reclined position. The cradle upper portion includes arm rests movable therewith for supporting hand flight controls. Foot flight controls are mounted to the cradle lower portion which is formed by a pair of leg rests. The assembly includes a separable, non-articulated ejection seat removably carried by and stationary with respect to the cradle upper portion during non-ejection use. The seal is moved with the cradle upper portion as the cradle upper portion pivots between the upright and reclined positions. The seat is movable upon ejection independent of the cradle with the cradle and the hand and foot controls remaining in place within the aircraft during ejection. A power actuator is provided for selectively, angularly moving the cradle upper portion between the upright and reclined positions. A controller is provided to control operation of the actuator in response to sensed G-force at the pilot's station and anticipatory aircraft G-force related performance based upon aircraft stick position, angle of attack and other parameters.
