Head and neck restraint system

A head and neck restraint system includes a headpiece, a saddle, and tensioners connecting the headpiece to the saddle. The headpiece resides on top of a crew member's head and the saddle includes a saddle strap residing under the crew member's buttocks. The tensioners are pneumatic muscles which contract when a flow of gas is provided by gas generators. The gas generators are triggered by a G-sensor or by the initiation of a predetermined event. Triggering signals pass through a manifold from an ejection seat, aircraft, or vehicle. Contraction of the pneumatic muscles pulls the headpiece toward the saddle, thereby restraining the head, neck, and spine. The system is worn as an undergarment or incorporated into a garment. A manual adjustment provides head support during flight. The system is particularly useful for preventing head and neck injuries during ejection from or crash of an aircraft or vehicle

Aircraft ejection seat with movable headrest

An ejection seat includes a headrest that, upon initiation of the ejection seat, moves forward to support the pilot's head in a tilted-forward position. By holding the crewmember's head in a tilted-forward position, windblast forces are controlled to prevent the helmet from pulling upward and backward on the crewmember's head. The headrest may include a pair of struts that extend forward around the sides of the crewmember's helmet to support the crewmember's head against flailing from the windblast. A flexible panel extending between the struts and the headrest panel may also be included to further support the crewmember's head against windblast flailing.

Passive ejection seat arm flail restraint apparatus and method

ActiveUS20110114790A1Preventing arm flail injuryAvoid flailingSupports/holding devicesAircraft ejection meansEjection SeatsEngineering
An ejection seat arm flail injury prevention apparatus comprises a pair of rigid support arms on each side of the ejection seat that deploy outwardly to support a semi-rigid backstop substantially behind the ejection seat occupant. When the ejection seat is propelled out of the aircraft and is subjected to the windblast, the occupant's arms are allowed to flail in a rearward direction in the windblast until the occupant's arms impact the semi-rigid backstop. The backstop is semi-rigid in that it deforms sufficiently to enable the rearward motion of the occupant's arms to be arrested without impact injury, yet is sufficiently rigid to prevent the occupant's arms from rebounding off the backstop or striking the rigid support arms.
