Ejection restraint systems for flight suits

A high tensile tape or cable is sewn into pockets in the arms of a flight suit. The pockets are closed over the tape or cable by a frangible thread. A non-frangible thread secures one end of the tape or cable to the wrist of the flight suit. The other end of the wire or cable is secured to a fastener that is adapted to connect to a ring member in the aircraft. The ring member is fastened to a tape or cable wound on a haul-back reel in the aircraft seat. Upon receipt of an ejection signal, the haul-back reel winds the tape or cable rupturing the frangible threads securing the pockets in the arms of the flight suit. The tape or cable pulls the arms up and against the chest of the air crewmember.

Inflatable restraint systems for ejection seats

An inflatable restraint system for holding and securing an aircrew member in his seat during ejection from an aircraft has one or more members forming a shield around him or her. The system is controlled to inflate after the aircrew member has started the sequence of ejection and before the rockets that power the seat from the aircraft are ignited. The forces of windblast are deflected by the inflatable restraint from the aircrew member as the aircrew member enters into and remains in the windblast and in his seat.

Inflatable restraint systems for ejection flight vests

One or more tubular inflatables are mounted in pockets spaced around a flight vest to assist and maintain upper body stiffness during ejection. The inflatables function to maintain the body stiff and prevent its moving from side to side during ejection. By proper positioning of the inflatables around the body, spinal compression may be prevented. In addition, connected to the flight vest is a collar-like inflatable that supports and protects the neck and head of the air crewmember from moving. The collar-like member can encircle the neck like a scarf. In another embodiment, it can also extend above the shoulders and completely encircle the helmet holding the head in a vertical position. In each embodiment, the collar-like member properly maintains the center of gravity of the air crewmember on the aircraft seat.

Restraint system for a flight helmet

A restraint system for a flight helmet that functions to hold the head steady and centrally located in the aircraft seat. The inflatable is stored on the helmet and upon activation of an ejection sequence. The inflatable member is inflated and breaks a frangible cover to rest on the shoulders. In addition, the inflatable member operates to seal the neck and, in another embodiment, to shield the face from the windblast the air crewmember encounters during ejection. The inflatable member can also function to lift the head and reduce spinal compression encountered during ejection.

Restraint system for a flight helmet

A restraint system for a flight helmet (30) that functions to hold the head steady and centrally located in the aircraft seat (20). The inflatable (32) is stored on the helmet and upon activation of an ejection sequence. The inflatable member (32) is inflated and breaks a frangible cover (34) to rest on the shoulders. In addition, the inflatable member operates to seal the neck and, in another embodiment, to shield the face from the windblast the air crewmember (22) encounters during ejection. The inflatable member can also function to lift the head and reduce spinal compression encountered during ejection.
