Description
Technical field
The present invention relates to the auxiliary body of a kind of chair, particularly relate to damper regulation mechanism and the end of a kind of back of the body linkage chair
Seat link gear.
Background technology
The office accommodation that office chair is important in living as routine office work, the level of comfort of chair is directly connected to people's
The quality of worklife.At present a lot of office chair in market all has altitude mixture control and a function of tilting angle of backrest regulation, and in order to
Make the laminating of the chair back and human body waist more comfortable, simultaneously in order to user during the reclining chair back safer, more and more
Office chair have employed the chair back and seat support linkage structure, but this linkage chair due to arrange extension spring be uncontrollable,
And the build of people, weight etc. differ, in actual use, the people that body weight is big may feel that the restoring force of extension spring is too small,
During reclining, reclining the most suddenly is excessive, and overturning even occurs；And the light people of body weight easily feels that the restoring force of extension spring is excessive,
Need backrest is applied bigger power during reclining, rest effect is produced impact.
The drawbacks described above existed for office chair in the market, applicant also invented the damping regulation of a kind of back of the body linkage chair
Mechanism, and patent application, Application No. 201510136703.1 can have been carried out.This device includes damping regulation substrate, L-type plate, L
Template driving means and extension spring, described extension spring one end is fixed on seat support front end, and the other end of extension spring is connected with damping regulation substrate,
Damping regulation substrate is slidably connected with base, and described L-type plate includes that the junction of transverse arm and vertical arm, transverse arm and vertical arm is cut with scissors with base
Connecing, the free end of transverse arm and damping regulation substrate are hinged, L-type plate with the pin joint of its two-arm junction as fulcrum, vertical arm
Free end L-type plate driving means being rotated by and by transverse arm band dynamic damping regulation substrate move.
The damping adjustment device of this seat back of the body linkage chair seat support drives L-type plate to rotate by L-type plate driving means
Thus band dynamic damping regulation substrate moves forward and backward so that the amount of tension of extension spring original state changes, and then realizes backrest and exist
During reclining, changing of the size of the restoring force that seat support is subject to, so that chair is adapted to different building shape Man's Demands.
But the damping adjustment device complicated structure of this seat back of the body linkage chair seat support, production cost is higher, Er Qieyou
In L-type plate rotate institute can band dynamic damping to regulate the stroke adjustment amount of substrate limited, therefore this adjusting means in actual use
The effect played is little, and regulating effect is inconspicuous.
Summary of the invention
In order to solve above-mentioned technical problem, it is an object of the invention to provide a kind of simple in construction, chair back restoring force regulates

The present invention compared with prior art, has the advantage that
The invention provides a kind of structure more simply damper regulation mechanism of chair but the range of accommodation wider array of seat back of the body links.With lever
Principle is theoretical foundation, i.e. F1 L1=F2 L2, power × power arm=resistance × resistance arm.Resistance arm is changed by regulation
Size, thus change the size of the moment of resistance, the different initial arm of forces be set according to the build of different people, thus adapt to everyone
Use demand, use linkage chair during, linkage chair can steadily operate all the time.
Specifically, at rocker in the rotation process of pin joint, the rotation of rocker is played inhibition by elastomer, i.e. carries
For resistance, its resistance arm is the vertical dimension that drag direction arrives pin joint, and rocker is rotated and provides driving force, its application point by external force
For the other end of rocker, the vertical dimension in driving force direction to pin joint is power arm, and at rocker rotation process each time
In, its arm of force size is almost consistent only minute differences all the time, because different people is different to the perception of the size of power, and root
According to lever principle F1 L1=F2 L2, power × power arm=resistance × resistance arm, can be had by the size of regulation resistance arm
The size of the driving force required for effect regulation.Thus can be filled by regulation according to the different people different perception to the size of power
Put the abutted position of regulation elastomer and rocker, thus change the size of resistance arm, and then realize backrest during reclining, chair
Changing of the size of the moment of resistance that seat is subject to, thus the size of the initial drive force needed for changing, thus adapt to the need of different people
Ask, in use, both will not feel that backrest was the heaviest, also will not be because the moment of resistance is the least suddenly toward tipping backwards.
