When mutually changing, human body back can be subjected to displacement relative to backrest, the comfortableness of experience lf being influenced.
The content of the invention
The purpose of the present invention, is that be can adjust to solve the above problems there is provided a kind of backrest, have sofa and chaise longue function concurrently
And the sofa of the seat cushion with the different positions that can be self-regulated of sofa state is provided with backrest.
Technical proposal that the invention solves the above-mentioned problems is as follows：
A kind of adjustable sofa of backrest, including seat cushion and the backrest on the seat cushion, the seat cushion and described
Backrest is hinged by jointed shaft, and the bottom of the backrest is provided with support beam, the support beam and at least one air supporting
Bar is connected, and the air supporting bar is arranged on below the seat cushion；Back cushion slidably is provided with the backrest, it is described to lean on
The top of pad is connected with one end of elastic component, and the other end of the elastic component is connected with the top of the backrest；The back cushion
Bottom is connected with one end of transmission belt, and the other end of the transmission belt is connected to the top of the backrest, and the transmission belt is passed through
One driving section, the transmission portion is hinged in the bottom or lower section of the backrest, the position of its horizontal direction compared to described
Axle is closer to the one end of the seat cushion away from the backrest.
Human body is taken on the seat, and usual stern thigh will not nestle up backrest, then when sofa is transformed into chaise longue state,
Backrest is rotated backward, and the back of human body will be subjected to displacement relative to backrest；Back cushion is originally used for supporting the waist of human body, backrest
When rotating backward, back cushion can be moved up relative to the position of human body back, hinder people when being in chaise longue state superincumbent not
Figure is ceased, it is not only uncomfortable, also easily cause spinal lesion.

Sliding surface causes when back cushion or human body back are moved thereon resistance to reduce so that when backrest is rotated down, and human body back and leans on
Pad movement is smooth.
As the preferred of above-mentioned technical proposal, the backrest is internally provided with continuous space, the elastic component and described
The other end of conveyer belt is connected in the space.
As the preferred of above-mentioned technical proposal, the length of the chute is less than the back cushion on the slide direction
Length.
As the preferred of above-mentioned technical proposal, the elastic component is two, is symmetrically connected to the two of the back cushion top
End.
As the preferred of above-mentioned technical proposal, the driving section is fixed pulley.
As the preferred of above-mentioned technical proposal, the elastic component is the rope that spring or elastomeric material are made.
In summary, the invention has the advantages that：
The adjustable sofa of a kind of backrest of the present invention can mutually be changed between sofa state and chaise longue state,
And the back cushion with state difference self-regulation position is provided with backrest, meet human body requirements, use experience more preferable；Further
