Zusammenfassung:	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 oerates 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.
