Preferred as technique scheme, described backrest is internally provided with continuous print space, and the other end of described elastic component and described transmission band is connected in described space.
Preferred as technique scheme, the length of described chute is less than described back cushion length on described slide direction.
Preferred as technique scheme, described elastic component is two, the symmetrical two ends being connected to described back cushion top.
Preferred as technique scheme, described driving section is fixed pulley.
Preferred as technique scheme, the rope that described elastic component is spring or elastomeric material is made.
In sum, this utility model has the advantage that
A kind of adjustable sofa of backrest described in the utility model mutually can be changed between sofa state and chaise longue state, and is provided with the back cushion with state difference self-regulation position on backrest, meets human body requirements, uses experience more preferably；Further, by arranging matte on seat cushion and back cushion, backrest is that shiny surface further increases riding comfort simultaneously, also by the figure that holding is correct, favourable to health.
