The working principle of embodiment: when office worker is sitting on office chair, sucker 32 is fixed on the ground, seat
Contact situation automatic lifting of the adjustment module 6 according to buttocks with seat 1, multiple universal formation of rotating plate 13 can effectively be bonded support
The curved surface of buttocks.Since universal rotating plate 13 with tilt rotation, can support the curved surface of buttocks can more smooth transition.Due to universal turn
The raising and lowering speed of plate 13 is more constant, and office worker can experience one during sitting posture adjusts or sits down and stands
The comfortable damping sense of kind, better user experience.When office worker leans forward or swings back, due to gravity center shift, 20 He of upper boom
Angle between lower beam 21 changes, and the angle and backrest 3 on seat 1 and ground and the angle on ground change simultaneously,
The both ends of block 24 make office chair will not excessive top rake to that can limit to the angle change between upper boom 20 and lower beam 21
With excessive layback, office chair is avoided to fall down.Office worker can also be waved on office chair using the elasticity of return spring 23, this
Utility model has both the purposes of rocking chair.By rotating long nut 27, mutual synchronous with the second screw rod 26 of the first screw rod 25 can be made
Mutually close to or far from so that the length of adjuster changes, corresponding is the variable angle between upper boom 20 and lower beam 21, right
What is answered is the variation of 1 height of seat, different height office worker can be suitble to use with this.
Therefore, the utility model can all carry out the buttocks under different sitting postures being bonded support well, and having can prolong
The advantage of slow office worker's fatigue, and the office worker of different weight, using that can obtain comfortable effect, furthermore this is practical
Novel angle is adjustable, is suitable for various office scenes, in addition the seat height of the utility model is adjustable, is suitable for
The office worker of different height uses.
