It is dynamic.
Further, there are two the connecting plate component settings, the two sides of the backrest module are separately mounted to.
Further, the backrest module includes backrest frames and filling member, and described two connecting plate components are mounted on backrest
The two sides of skeleton are rotatablely connected with backrest frames.
Further, the riveting of the connecting plate component is connect with backrest frames end has a bushing, and by shoulder bolt with
Backrest frames connection；The riveting of end that the connecting plate component is connect with lower bracket component has a bushing, and by shoulder bolt with
The connection of lower bracket component.
Further, backrest frames are bolted with upper bracket component, and backrest frames can be revolved by the center of circle of bolt
Turn.
Further, the sliding rail has self-locking device, so that upper bracket component can be fixed with respect to lower bracket component.
After above-mentioned technical proposal, the utility model has the following beneficial effects:
When the upper bracket component of the utility model travels forward, lower bracket component is fixed, the bottom of backrest module by
It to forward power, travels forward with upper bracket component, since backrest module is connected to lower bracket component by connecting plate component 5
On, it is limited by connecting plate component and lower bracket component, therefore backrest module integrally generates the movement of back rotation.The utility model energy
By the movement moved forward and backward to drive backrest module to upper bracket component, and upper bracket component is used to install seat cushion, thus
Reach the function of key regulation chair angle and position.

Specific embodiment
In order to make the content of the utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model.
Unless not defining, the technical term or scientific term used herein is should be in the utility model fields
The ordinary meaning that personage with general technical ability is understood.Used in the utility model patent specification and claims
" first ", " second " and similar word are not offered as any sequence, quantity or importance, and are used only to distinguish different
Component part.Equally, the similar word such as "one" or " one " does not indicate that quantity limits yet, but indicates there is at least one
It is a.
As shown in Figures 1 to 5, a kind of linkage mechanism for seat, including backrest module 1, upper bracket component 2 and lower branch
Frame component 3, upper bracket component 2 is for installing seat cushion and driving seat cushion mobile, between upper bracket component 2 and lower bracket component 3
It is connected using sliding rail 8, so that upper bracket component 2 can slide back and forth with respect to lower bracket component 3；
The bottom of the backrest module 1 is rotatably connected with the upper bracket component 2, the middle part of the backrest module 1
Divide and connect by a connecting plate component 5 with the lower bracket component 3, also, the connecting plate component 5 is connect with backrest module 1
End with respect to backrest module 1 can be rotated, the connecting plate component 5 is lower opposite with the end that the lower bracket component 3 connects
Frame component 3 can be rotated.
When the upper bracket component 2 of the utility model travels forward, lower bracket component 3 is fixed, the bottom of backrest module
It by forward power, travels forward with upper bracket component 2, since backrest module 1 is connected to lower bracket group by connecting plate component 5
On part 3, it is limited by connecting plate component 5 and lower bracket component 2, therefore 1 entirety of backrest module generates the movement of back rotation.This is practical
