    摘要: A device for opening a passenger door of an aircraft includes a supporting arm connected movably to the fuselage frame, a wishbone connecting the support arm to the passenger door, a first journal rotatably connecting the wishbone to the support arm, and a lifting mechanism. The lifting mechanism includes a lifting shaft for raising and lowering the door, a lowering safety shaft, a controllable drive engaged with the lowering safety shaft to rotate lowering safety shaft, and a lowering safety link. The lifting shaft includes two ends and a roller lever disposed at each end, wherein when the passage door is in the closed position, each roller lever engages a fuselage frame mounting. The lowering safety shaft includes an end and a roller lever disposed at the end. The lowering safety shaft is engaged with the lifting shaft. The lowering safety link includes a second journal having an elongated configuration. The second journal has a link track, and the roller of the lowering safety shaft is guided on the link track of the second journal.
