The invention discloses a head and neck protection device for pilot ejection lifesaving and an aircraft ejection seat, and belongs to the technical field of pilot neck protection. The head and neck protection device comprises a conduction device and a gas cylinder triggering mechanism; the conducting device is respectively connected with the safety airbag and the gas cylinder; the gas cylinder triggering mechanism comprises a shell, an electromagnetic ejection mechanism, a firing pin, a sliding seat, an elastic device and a rotary locking block; the firing pin is installed at one end of the sliding seat and is coaxial with the gas cylinder, the elastic device is arranged at the other end of the sliding seat, the rotary locking block is rotatably installed in the shell, the electromagnetic ejection mechanism is hinged to one end of the rotary locking block, and when the elastic device is in a compressed state, the other end of the rotary locking block abuts against the positioning table; when the rotary locking block is separated from the positioning table, the firing pin opens the gas cylinder under the action of elastic force, so that compressed gas is injected into the safety airbag; the head and neck protection device can protect the head and the neck of a catapult in the emergency catapulting process, and the head and neck damage occurrence rate caused by emergency catapulting is reduced.

    本发明公开了一种飞行员弹射救生的头颈部防护装置及飞机弹射座椅,属于飞行员颈部防护技术领域,该头颈部防护装置包括导通装置和气瓶触发机构;导通装置分别连接安全气囊和气瓶;气瓶触发机构包括壳体、电磁弹射机构、撞针、滑座、弹力装置和旋转锁块;撞针安装在滑座的一端并与气瓶同轴设置,弹力装置设置在滑座的另一端,旋转锁块转动安装在壳体中,电磁弹射机构与旋转锁块的一端铰接,当弹力装置处于压缩状态下,旋转锁块的另一端与定位台抵接;当旋转锁块与定位台分离,撞针在弹力的作用下开启气瓶,使压缩气体注入安全气囊;该头颈部防护装置可以在应急弹射过程中保护弹射人员头颈部,并降低应急弹射造成的头颈部损伤发生率。
