Description
Technical field
The utility model is related to a kind of auxiliary body of back of the body linkage chair, more particularly to a kind of spacing tune of back of the body linkage chair
Section mechanism.
Background technology
Office chair office accommodation important in being lived as routine office work, the level of comfort of chair is directly connected to people's
The quality of working life.The many office chairs in current market use universal chassis, due to backrest and the man-machine size matching relationship of seat surface
Without investigating, during reclining, backrest particularly Lumbar departs from human body waist to user, between the two is directly formed vacantly
Gap, causes the seat under reclining state to lose the support to human body waist, is exactly " race waist " that we are commonly called as, and human spine is obtained not
Cause the health problem of many sittings to effectively support；Simultaneously as using universal chassis, the man-machine size of backrest and seat surface
With relation without investigating, during reclining, buttocks is relatively fixed user with seat surface, and backrest is upward with respect to human body back
Friction, causes the discomfort of " clothes is pulled in chopping ", also causes indecency perception.In addition, user is during reclining, with
The layback of backrest, the center of gravity of human body also moves the carrying center of gravity for deviateing seat after, is susceptible to overturn, and there is potential danger.
For the defect that office chair in the market is present, a kind of seat back of the body linkage chair of applicant's new invention has simultaneously carried out patent
Application, Application No. 201510136967.7.The linkage chair includes the handrail of base, seat support, backrest and seat support both sides, described to help
Hand is rigidly connected with base, and the backrest left and right sides is hinged with two handrails respectively；The seat support includes being used to assemble cushion
Mounting and the slide plate that is slidably connected with base, the rear end of mounting is provided with a support, the support axisymmetricly, support
Two ends are hinged with the backrest left and right sides respectively.Mounting front end is hinged with slide plate, and mounting is front and rear same when backrest is rotated with slide plate
Step motion, is provided with the elastic recovery mechanism for making slide plate reset in base.This linkage chair is any during backrest reclining
Angle, backrest is close to human body back and is not subjected to displacement all the time, and comfortableness is strong；Simultaneously because while being leaned on after backrest, seat support conveying
Human body is moved forward, and moderately supplements the problem that the center of gravity that reclining brings backward retrodeviates shakiness.
But, during reclining backward, backrest can only when elevation angle reaches maximum for this linkage chair
It is supported, the dependence that now user can just be stablized.Build and rest custom yet with people is different, and only one of which is leaned on
The demand of most of user is not obviously adapted to by angle.
