  • Aircraft ejection seat with passive limb retention
    Patent number: 8162259
    Abstract: An aircraft ejection seat includes a passive limb retention system. The limb retention system comprises a primary lanyard that forms a loop around the crewmember's footwell and a secondary lanyard that is releasably attached to a medial portion of the loop in the primary lanyard. Upon initiation, as the ejection seat is propelled out of the aircraft, the primary and secondary lanyards simultaneously close the lanyard loop around the crewmember's leg from both ends until the lanyard loop contacts the crewmember's leg. Once the lanyard loop is closed around the crewmember's leg, the secondary lanyard releases, allowing the primary lanyard to continue to tighten around the crewmember's leg until the shear fastener shears and the ejection seat exits the aircraft.
