Problems solved by technology

[0002] The gas spring on the aircraft seat mainly provides a certain thrust for the seat lift adjustment. After the gas spring is installed, the stroke cannot be changed, but in practice, it may be necessary to adjust the compression amount of the gas spring to obtain different thrust and stroke, which cannot be adjusted. The gas spring of the stroke causes great inconvenience to the user

Embodiment Construction

[0013] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0014] like figure 1 , figure 2 As shown, the adjusting device of the aircraft seat air spring of the present invention includes an air spring telescopic rod 6 , an adjusting block 2 and an adjusting bottom frame 3 .

[0015] A blind hole 10 is provided inside the adjusting block 2 , and the blind hole 10 is located in the middle of the adjusting block 2 . The gas spring 1 is used to be connected with the upper bracket 5 on the seat. The end of the gas spring telescopic rod 6 is pushed against the bottom of the blind hole 10, and when the adjusting block 2 moves up and down, the end of the gas spring telescopic rod 6 moves up and down thereupon. The adjustment block 2 is threadedly connected with the adjustment bott...

Abstract

The invention relates to an adjustment device for an air spring of an aircraft seat. The adjustment device comprises an air spring telescopic rod (6), an adjustment block (2) and an adjustment underframe (3). A blind hole (10) is formed in the adjustment block (2). The end of the air spring telescopic rod (6) is abutted against the bottom of the blind hole (10). The adjustment block (2) is connected with the adjustment underframe (3) in a threaded mode. According to the adjustment device for the air spring of the aircraft seat, the height of the adjustment device can be adjusted by rotating the adjustment block, the position of the end of the air spring telescopic rod is changed accordingly, so that the compression amount of the air spring is changed, and the stroke for adjusting the air spring and the stroke for adjusting the seat up and down are completed. The adjustment device for the air spring of the aircraft seat is simple in structure, reliable in performance ad low in cost, can be widely applied to aircraft seats and has great use value.

Description

technical field [0001] The invention relates to the field of installation of aircraft seat gas springs, in particular to an adjustment device for aircraft seat gas springs. Background technique [0002] The gas spring on the aircraft seat mainly provides a certain thrust for the seat lift adjustment. After the gas spring is installed, the stroke cannot be changed, but in practice, it may be necessary to adjust the compression amount of the gas spring to obtain different thrust and stroke, which cannot be adjusted. The gas spring of the stroke causes great inconvenience to the user. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an aircraft seat gas spring adjustment mechanism with simple structure, convenient operation and convenient adjustment. [0004] The technical solution adopted by the present invention to solve the technical problem is to construct an adjustment device for an aircraft seat gas spring, in...
