Abstract
A system for assisting a fighter pilot in checking the six-o'clock position. By differentially inflating bladders placed under the seat cushion of the ejection seat of a fighter, the seat cushion can be rotated to the pilot's left or right to aid the pilot in checking the space directly behind the fighter. A system controller, responsive to actions by the pilot, causes the differential inflation of the bladders and controls the rotation of left and right harness straps. The system controller can actuate solenoid valves to control the bladder inflation or can mechanically rotate a fluid valve to control the bladder inflation. The bladders can be fabricated from a resilient material so that they automatically deflate when they are vented to the ambient atmosphere and their size can be limited by placing the bladders inside a resilient casing that has a non-resilient web connecting the opposed surface of the casing.
