Abstract
Abstract An improved anti-G suit incorporates stiffening inserts sized and shaped to cover each inflatable air bladder and inserted between the bladders and the anti-G suit fabric. The stiffeners may be made of polypropylene, neoprene rubber, or a composite structure of Kevlar® fabric and polyethylene. A butt strap covers the buttocks of an aircrew member and is secured by belts extending across the abdominal and the thigh bladders of the anti-G suit. Inflation of the air bladders pulls the butt strap belts to compress the butt strap tightly against the aircrew member's buttocks.
