Abstract

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.
