Handrail is articulated in the middle part of the chair back.
As a further illustration of the above scheme, at least two connecting rods are provided in the middle part of the support base, for fixing
And support the attachment base.
Further, the attachment base includes bottom plate and sliding slot panel, and sliding slot panel bottom is provided with and the company
The corresponding holding tank of extension bar.
Further, the depth of the sliding slot along moving direction from shallow to deep, the height of the protrusion along moving direction by
Down to height.
Further, it is provided with several hollow slots along the vertical direction inside the chair back, the bending for increasing the chair back is strong
Degree.
Further, the handrail includes articulated joint and the armrest body for being mounted on support base two sides, the chair back and institute
It is hinged with articulated joint to state armrest body.
Further, the support base is lifting type support seat, rotary support seat, arch support seat, four foot chair support bases
In any one.
The present invention is using the above-mentioned attainable beneficial effect of technical solution:
One, the present invention is between support base and seat by being arranged attachment base, simplifies linkage structure, demolition and maintenance or
Renewal part is convenient and efficient, while sliding slot is provided on the attachment base, and the seat bottom is provided with corresponding protrusion,
Sliding back and forth for seat is realized, user can according to need the adjusting that front-rear position is carried out to seat, before and after seat progress
The angular adjustment of the chair back is realized while adjusting.
Two, the present invention can also be during user faces upward by the chair back, before pushing seat by the angle change of the chair back
After move, realize the bidirectional modulation between the chair back and seat, user's usage comfort can be effectively improved.
Three, the depth of the sliding slot provided by the invention along moving direction from shallow to deep, the height of the protrusion is along moving
It from low to high, ignores so that facing upward the lifting for seat front end during, it is avoided to cause to oppress to thigh in direction.

Specific embodiment
The technical program is explained in detail below in conjunction with specific embodiment.
As shown in Figure 1-Figure 3, the present invention is a kind of seat that the linkage of the seat chair back is adjusted, including seat 1, the chair back 2, handrail
3 and support base 4, which is characterized in that the handrail 3 is fixedly mounted on 4 two sides of support base, fixed at the top of the support base 4
Attachment base 5 is installed, sliding slot 5-1 is provided on the attachment base 5,1 bottom of seat is provided with corresponding with the sliding slot 5-1
Protrusion 1-1, the seat 1 is articulated with 2 bottom of the chair back, and the handrail 3 is articulated with 2 middle part of the chair back.
As a further illustration of the above scheme, as shown in figure 3, being provided at least two connections in the middle part of the support base 4
Bar 4-1, for fixing and supporting the attachment base 5；The attachment base 5 includes bottom plate 5-2 and sliding slot panel 5-3, the sliding slot
The bottom panel 5-3 is provided with holding tank 5-4 corresponding with the connecting rod 4-1.
Further, as shown in figs. 3 and 5, the depth of the sliding slot 5-1 along moving direction from shallow to deep, the protrusion 1-
1 height along moving direction from low to high.
Further, as shown in figure 5, being provided with several hollow slots 2-1 inside the chair back 2 along the vertical direction, increase institute
State the bending strength of the chair back.
Further, as shown in figure 4, the handrail 3 includes the articulated joint 3-1 and handrail master for being mounted on 4 two sides of support base
Body 3-2, the chair back 2 and the armrest body 3-2 and articulated joint 3-1 are hinged.
When practical application, as shown in figs 1 to 6, the handrail 3 is fixedly mounted on 4 two sides of support base, the connection
Seat 5 is mounted on the support base 4, and the seat 1 is articulated with 2 bottom of the chair back, and the handrail 3 is articulated with the chair back 2
Middle part；The handrail 3 includes being mounted on the articulated joint 3-1 and armrest body 3-2 of 4 two sides of support base, the chair back 2 and described is helped
Hand main body 3-2 and articulated joint 3-1 are hinged, therefore armrest body 3-2 can be rotated around articulated joint 3-1, and user can according to need
It is adjusted.Sliding slot is provided on attachment base simultaneously, seat bottom is provided with protrusion corresponding with sliding slot, and seat and attachment base connect
After connecing, the front-rear position of seat can be adjusted along the chute, since attachment base is fixedly connected with support base, seat relative to
