Whole angle adjusting mechanism of seat

Abstract

The invention relates to a whole angle adjusting mechanism of a seat. A gas spring and a lifting mechanism are combined so as to achieve whole angle adjustment of the seat. The gas spring and the lifting mechanism are arranged in parallel. The lifting mechanism comprises a locking tooth plate, a locking pin, a spring, pin teeth and tooth grooves, wherein the plurality of tooth grooves are formed in the locking tooth plate; the pin teeth which correspond to the tooth grooves are disposed at one end of the locking pin; the spring is disposed at the other end of the locking pin in a sleeving modeso as to provide pre-tightening force for the locking pin; the end of the locking pin is connected with a steal cable; the locking pin is put on a base to be matched and connected with the base; andthe steel cable is pulled tightly or loosened, the pin teeth at the front end of the locking pin are engaged with or disengaged from the tooth grooves so as to achieve locking or unlocking. The wholeangle adjusting mechanism has the advantages of being simple in structure, good in strength and stability and convenient to install.

Description

technical field [0001] The invention relates to an overall angle adjustment mechanism of a seat, in particular to an overall pitch angle adjustment of a seat surface and a backrest of an aviation pilot's seat. Background technique [0002] With the opening of low-altitude fields and the improvement of people's living standards, airplanes are used more and more widely as a means of transportation. Therefore, the modern aviation industry pays more and more attention to the comfort of aviation seats. However, the cockpit space is small, and the strength requirements of the driver's seat, especially the dynamic impact performance, are extremely strict. Many seat designs need to sacrifice the comfort experience to meet the strength requirements. At present, the aviation pilot's seat can only realize the individual adjustment of the backrest angle, and there is no overall pitch angle adjustment device for the seat surface and the backrest used in the pilot's seat. Aiming at this...
