Abstract : A ring-shaped inflatable head/neck restraint system for ejection seats is being developed at the Crew Systems Department, NADC. The purpose of this system is to reduce neck injuries due to violent forward head rotation at the time of ejection thrust and parachute opening shock. Inflation of the neck ring will be conducted by a solid propellant gas generator. Design considerations include form-and-fit, cost effectiveness, packaging and integration into life support equipment.
