Description
Technical field
The utility model is related to the chairs that a kind of chair more particularly to a kind of chair back seat link.
Background technology
Chair is as life, the essential life tool of working environment at home, and not only life uses chair at home
There is more and more high comfort requirement, even working environment also has the comfort of chair and operability under the premise of working efficiency
It is obviously improved requirement, general chair, can not be simultaneously when the user's chair back of the design limitation on traditional chassis structure is swung back
The corresponding displacement for completing seat is generated and is changed with the longitudinal separation of seat in layback due to the chair back, constant in seat position
In the case of, with user back relative displacement and friction occur for the chair back, lead to sense of discomfort, even if individual existing products can be same at present
The function of Shi Shixian seat displacements, but it is also unable to reach the linkage effect of engineering, cause the deficiency and operability of comfort
It is complicated.
Although having there is Chinese utility model patent（The patent No.：ZL2015206115371, patent name：The swivel chair seat back of the body is same
Step displacement system）A kind of structure of the chair back and seat linkage is disclosed, the structure in the patent includes seat glue shell, chair back sliding
Link, chair back frame and seat pedestal, the be slidably connected upper end of frame of the chair back are fixed with chair back sliding bar, and chair back sliding bar one end connects
It is connected to the chair back and slides ball, the chair back is slidably connected the lower end connection seat pedestal of frame；It is provided with chair back frame sliding slot, the chair back on the inside of chair back frame
It slides in ball insertion chair back frame sliding slot, chair back frame lower end is cased with chair back shaft sleeve, and the chair back is cased on the chair back shaft sleeve and is turned
Axis fixator, the chair back rotor shaft fixer are fixed on seat glue shell lower end；Seat glue shell lower end is fixed with Return spring, this is pulled back
The lower end of spring connects seat pedestal, is connected on the seat pedestal and slides connector, this slides connector and also connects seat glue
Shell.When it can easily realize chair back layback, it is completed at the same time the corresponding displacement of seat cushion.
But the structure of the patent can only realize the horizontal displacement of seat, and since sliding bar only has one end in the structure
It is connected with the chair back and slides ball, the linkage of the chair back and cushion may be caused unstable, experience effect is poor.In addition the structure is whole more multiple
Miscellaneous, shared volume is also big, and need to carry out special designing to seat, and versatility is poor, increases the cost of the manufacturing, influences
Yield rate.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide the simple in structure, chair back of one kind and seat
The chair of linkage, which can change the position of seat during the chair back is swung back, so that user back and the chair back
It not will produce friction, improve comfort.
In order to realize that above-mentioned purpose of utility model, the utility model use technical solution below：
A kind of chair, including chair chassis, seat and the chair back, chair chassis are slidably connected by first component and seat,
Second component is fixedly connected on the chair back, the second component is hinged with seat, and the chair back is slided by the second component and chair chassis
Dynamic connection.
