Problems solved by technology
Disadvantages of the prior art method When the plane crashes, the pilot's seat is passively deformed, and its motion stroke is usually less than 200mm limited by the deformation of the aircraft structure, resulting in a relatively large impact force on the human body, and the seat motion direction has a very large Uncertainty, thus unable to achieve effective protection of the human spine

The invention discloses a pilot seat anti-collision protection device for a navigation airplane. The device includes an anti-collision rod, a seat connection assembly and a sliding rail assembly; theseat connection assembly is connected to and mounted at the upper end of the anti-collision rod and connected with a seat, and the sliding rail assembly is connected to and mounted at the lower end ofthe anti-collision rod; the anti-collision rod includes an outer pipe and an inner pipe, the outer pipe sleeves one end of the inner pipe, the outer pipe is fixed to the inner pipe through a safety pin, and the other end of the inner pipe is provided with a fixing connector; the seat connection assembly includes a seat support, a supporting rod, a seat sliding rail supporting plate and a connection clapboard; a mounting connector is arranged on the side surface of the outer pipe and fixed to the end, close to a backrest, of the seat support through bolts; the sliding rail assembly comprises afixing sliding rail and a sliding rail locating pin. The device has an overloading protection function and a directional movement limiting function and can achieves initiative directional large-stroke buffering movement of the seat when an airplane falls and is collided, and under combination with a structural deformation energy absorption measure, effective protection for the human body is formed.
Description
【Technical Field】 [0001] The invention relates to the technical field of pilot seat protection equipment, in particular to the technical field of a pilot seat collision protection device for general aviation aircraft. 【Background technique】 [0002] The current pilot seat for general aviation aircraft uses two independent systems for position adjustment and crash protection. That is, the slide rail mechanism fixed on the floor is used to realize the adjustment of the front and rear and up and down positions of the seat; the energy absorbing part is added to the lower part of the seat to protect the human body when the plane crashes. [0003] The analysis proves that when the plane crashes, only when the human body motion stroke reaches 300 mm, the force value of the human spine can be controlled within the acceptable range of the human body. Disadvantages of the prior art method. When an airplane crashes, the pilot seat is passively deformed, and its movement stroke is usually lim...
