Abstract
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.
