Description
Technical field
The present invention relates to thing to sit on technical field, be specifically related to the adjustable sofa of a kind of backrest.
Background technology
Sofa is one of thing to sit on of commonly using the most, the thing to sit on of taking while being people's daily leisure, rest, and prior art can become sofa chaise longue and the two-in-one thing to sit on of sofa function, to increase its function and the scope of application.
Granted publication number is that the Chinese utility model patent of CN203137687U discloses an a kind of double sofa that does chaise longue and bed use, and it adopts the angle of self-locking air spring control backrest to layback, to realize the conversion of sofa, chaise longue and a state; But back cushion is not set on its backrest, comfortable not while use as sofa and chaise longue, and in the time that sofa state and chaise longue state are changed mutually, human body back can be subjected to displacement with respect to backrest, the comfortableness of experience lf being influenced.
Summary of the invention
Object of the present invention, is in order to address the above problem, provide a kind of backrest adjustable, have sofa and the sofa being provided with on chaise longue function and backrest with the different seat cushions that can self-regulation position of sofa state concurrently.
The technical scheme that the present invention addresses the above problem is as follows:
The adjustable sofa of a kind of backrest, comprise seat cushion and be positioned at the backrest on described seat cushion, described seat cushion and described backrest are hinged by jointed shaft, the bottom of described backrest is provided with brace summer, described brace summer is connected with at least one air supporting bar, and described air supporting bar is arranged on described seat cushion below; On described backrest, be slidably provided with back cushion, the top of described back cushion is connected with one end of elastic component, and the other end of described elastic component is connected with the top of described backrest; The bottom of described back cushion is connected with one end of driving-belt, the other end of described driving-belt is connected to the top of described backrest, described driving-belt is through a driving section, described driving section is positioned at bottom or the below of described backrest, and the position of its horizontal direction more approaches described seat cushion one end away from described backrest compared to described jointed shaft.
Human body is taken on the seat, and stern thigh portion can not nestle up backrest conventionally, and in the time that sofa is transformed into chaise longue state, backrest rotates backward so, and the back of human body will be subjected to displacement with respect to backrest; Back cushion is originally for the waist of support human body, and when backrest rotates backward, back cushion can move up with respect to the position of human body back, hinders the superincumbent rest figure of people in the time of chaise longue state, not only uncomfortable, also easily causes spinal lesion.
The bottom of back cushion is connected with driving-belt by driving section with the top of backrest, when backrest rotates backward so, driving-belt can pull down back cushion, back cushion is with respect to backrest down sliding, ensure that back cushion is supported on the waist of human body all the time, no matter make, at sitting posture or under lying posture, can both to ensure the comfortable and correct set of human body.
As technique scheme preferably, described back cushion slides on chute, described back cushion is provided with limiting section near the one side of described backrest, described limiting section is stuck in and on described chute, limits described back cushion and depart from described backrest.
As technique scheme preferably, the upper surface of described seat cushion is provided with the groove matching with human body stern thigh contouring.
As technique scheme preferably, the upper surface of described groove is matsurface.
As technique scheme preferably, the surface of described back cushion is matsurface, the surface of described backrest is shiny surface.
When exasperate on seat cushion rotates backrest, the stern thigh portion of human body is difficult for being subjected to displacement, and when the shiny surface of backrest surface moves back cushion or human body back thereon, resistance reduces, and makes in the time that backrest rotates, and human body back and back cushion move smooth and easy.
As technique scheme preferably, described backrest inside is provided with continuous space, the other end of described elastic component and described conveyer belt is connected in described space.
As technique scheme preferably, the length of described chute is less than the length of described back cushion in described chute glide direction.
As technique scheme preferably, described elastic component is two, the symmetrical two ends that are connected to described back cushion top.
As technique scheme preferably, described driving section is fixed pulley.
As technique scheme preferably, described elastic component is the rope that spring or elastomeric material are made.
In sum, tool of the present invention has the following advantages:
The adjustable sofa of a kind of backrest of the present invention can mutually be changed between sofa state and chaise longue state, and on backrest, is provided with the back cushion with the different self-regulations of state position, meets human body requirements, uses and experiences better; Further, by seat cushion and back cushion, exasperate being set, backrest is that shiny surface has further improved riding comfort simultaneously, also by keeping correct figure, favourable to health.
