ABSTRACT:
A restraint system is provided for restraining a pilot in a safe position during high-acceleration conditions. A stationary harness portion is attached to the pilot's body and haulback straps are connected in a slidable manner to the stationary harness. Under normal conditions, the pilot has some freedom of movement to lean forward or move from side to side. In the event of high acceleration or other emergency conditions, a pair of haulback straps that are slidably attached at the mid-torso position of the pilot are retracted to bring the entire back of the pilot against the back support of his seat. Lateral support pads positioned at the back and side of the pilot are moved to provide support to the sides, ribs and lumbar regions of the mid-torso and to restrain side-to-side movement of the pilot. The position of the lateral support pads is automatically adjusted according to the size of the pilot.
