Further, the back bracket is additionally provided with handrail, the handrail installation on the fixed base with firm banking and branch
Support foot forms integral structure.
Further, the connection component is located at the medium position of back portion.
Further, the connection component is made of buffering adhesive every, connector and screw, and the buffering adhesive is leaned on every being located at
Between back braces and the link position of backrest body, the connector is made of an annular solid and multiple evagination latches, the evagination
Latch annular spread is on annular solid side, outer tappet tooth annular spread outer diameter size company corresponding with installing blind, described
Fitting side passes through annular solid by screw and is mounted on by back, and the connector other side is clamped on back bracket by evagination latch
Installing blind and card hole on.
Further, the backrest body is equipped with backrest protrusion, which is equipped with screw hole and location hole, described
Annular solid side is equipped with positioning protrusion, the positioning protrusion and location hole corresponding matching, and connector passes through screw and backrest protrusion
Screw hole, which is spirally connected, to be fixed on backrest body.
Further, the buffering adhesive is divided into ring-shaped rubber block, which is sleeved on the peace of support leg
In dress protrusion, the other end is sleeved in the backrest protrusion of backrest body, and makes to be reserved between buffering between back bracket and backrest body
Away from.
Further, the support leg includes upper support portion and lower support portion, the upper support portion and lower support portion
Between excessive position be in convex arc shape support construction, the upper support portion-of the support leg and lower support portion and backrest body
Back portion and waist portions correspond to each other.
Further, the support leg and handrail form the U-shaped structure of an inclined.
The present invention has substantive distinguishing features and significant progress following prominent:
1, backrest body of the invention is made of elastic material, which is fixed on the seat, and is being located at arc shape

When, arc shape structure between back portion and waist portions is backrest body bottom and seat be fixed and the back portion and backrest of backrest body
Under the action of bracket is fixed with human body waist forced contact.Therefore, in use, due to arc shape structure upper end (i.e. back portion
Position) by the way that in the fixed back bracket of connection component, the lower end of arc shape structure is fixed on the seat, i.e. the bottom of arc shape structure
Portion and top are fixed respectively, in backrest body hypsokinesis, back portion layback inclination, and arc shape knot when by the fixed seat of backrest body
Structure position forms the arc shape structural support human body waist of bigger radian (i.e. bigger protrusion) to human body waist position protrusion, right
Human body waist not only has the effect of relieving fatigue, and the impaired problem of lumbar vertebrae, more conducively people are easy to appear when also preventing from sitting for a long time
Raw body health.
2, back bracket of the invention is made of a firm banking and two support legs, and it is blind that band installation is equipped in support leg
The installation protrusion in hole, is equipped with card hole on installing blind side wall, and connection component is made of buffering adhesive every, connector and screw,
The buffering adhesive is every being located between back bracket and the link position of backrest body, and the connector is by an annular solid and multiple evaginations
Latch composition, the outer tappet ring gear shape are distributed on annular solid side, the outer tappet tooth annular spread outer diameter size and installation
Blind hole is corresponding, and the connector side passes through annular solid by screw and is mounted on by back, and the connector other side passes through evagination
Latch is clamped on the installing blind and card hole of back bracket.It can quickly be connected and fixed when thus installing, and screw is not exposed, peace
Fill simple and convenient, aesthetics is good.
3, buffering adhesive of the invention is divided into ring-shaped rubber block, which is sleeved on the installation protrusion of support leg
On, the other end is sleeved in the backrest protrusion of backrest body, and makes to be reserved with buffering spacing between back bracket and backrest body.By
This, when backrest hypsokinesis, by spacing and buffering adhesive every the interaction of buffering, preferably makes backrest hypsokinesis, and backrest body hypsokinesis
When, arc shape structure preferably forms bigger radian support human body waist.
4, back bracket of the invention is additionally provided with handrail, the handrail installation on the fixed base with firm banking and support leg
Integral structure is formed, therefore, structure is simple, easy for installation.
