ABSTRACT:
During ejection from a high performance aircraft, high wind blast conditions create danger of injuries caused by the flailing of limbs out of their desired positions. The invention provides a system that restrains the arms, legs, and head with one simple mechanism. A side net (28) and a knee strap (40) are attached to each of two center straps (22). Straps (22) extend forwardly from seat (2) to a tension fuse fitting (46) and down to snubbers (48). Deployment of straps (20, 40) and nets (28) is initiated by an inflatable member (20) that projects horizontally forwardly over the helmet (100) of the seat occupant. Deployment is completed by tensioning of straps (22) by upward movement of seat (2). When straps (22) reach a given tension, fittings (46) release straps (22) which drop down between the knees of the occupant. As straps (22) are further tensioned, nets (28) are pulled snugly around the front of the occupant, knee straps (40) are pulled snugly around the lower legs of the occupant, and member (20) is urged downwardly against the occupant's helmet (100).
