The invention discloses an aircraft cockpit seat damping device with an overtravel protection function, and relates to the technical field of seat damping, the aircraft cockpit seat damping device comprises a base, a top frame is arranged above the base, a damping mechanism is mounted between the center position of the base and the top frame, side strips are arranged on the two sides of the top of the base, and the side strips are arranged on the top of the base. Side openings are formed in the two ends of each side strip, two symmetrical overturning pieces are slidably inserted between the side openings between the two side strips, and telescopic limiting pieces abutting against one sides of the bottom ends of the overturning pieces are slidably inserted into the end faces, close to the middles of the side strips, in the side openings. When the overtravel protection jacking action is carried out during seat damping work, the position of upper frame damping up-down movement can be prevented from being changed, the situation that the natural settling position of a driver is too low after seat damping is recovered is prevented, the driving view of the driver is small in change amplitude, and use is convenient.

    本发明公开了一种具有超程防护功能的飞机驾驶舱座椅减震装置,涉及座椅减震技术领域,包括基座,所述基座上方设置有顶架,所述基座中心位置与所述顶架之间安装有减震机构,所述基座的顶部两侧均设置有侧条,所述侧条的两端均开设有侧口,两个所述侧条之间的所述侧口之间滑插有两个对称的翻转件,所述侧口内靠近所述侧条中部的端面滑插有与所述翻转件底端一侧抵触的伸缩限位件。本发明进行座椅减震工作时的超程防护顶升动作的同时能够避免顶架减震上下运动位置发生变化,防止驾驶员在座椅减震恢复后自然沉降位置过低,使得驾驶员的驾驶视野变化幅度较小,方便使用。
