Abstract
The invention discloses a structure for connecting a backrest and a headrest of a chair, wherein a rear part of the headrest is connected with a sliding bar, a rear side of the upper part of the backrest is provided with a sliding rail, a sliding groove is arranged in the sliding rail, he lower part of the sliding bar is arranged in the sliding groove in a penetrating manner and the sliding bar can sliding up and down along the sliding groove, the sliding rail is provided with a locking mechanism used for fixing the sliding bar in the sliding groove. According to the invention, through the matching of the sliding bar at the rear part of the headrest, the sliding rail at the rear side of the upper part of the backrest and the locking mechanism, the headrest can slide up and down; and since the top end of the backrest is provided with an elastic steel sheet barb part, the headrest has elastic deformation after one person leans on the headrest, and the person feel very comfortable.
Description
Technical field
The present invention relates to chair.
Background technology
The head rest of conventional chair and backrest are the fixing structure of one, and head rest can't be adjusted.Be difficult to satisfy different bodily form people's demand.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of back and head rest syndeton, realizes the adjustment of head rest and backrest.
For solving the problems of the technologies described above; The present invention adopts following technical scheme: a kind of back and head rest syndeton; It is characterized in that: the head rest rear portion connects a draw runner, and backrest top rear side is provided with slide rail, is provided with chute in the slide rail; The draw runner bottom is arranged in the chute and can slides up and down along chute, and said slide rail is provided with retaining mechanism draw runner is fixed in the chute.
As preferably, said backrest top is the crooked barb of side-lower backward, and said slide rail is fixed on the barb, and barb is an elastic steel sheet.
As preferably, said draw runner is an elastic steel sheet, and said draw runner upper end be the bending structure to front curvature, and said draw runner lower end is the bending structure of bending in barb.Top bending structure elastic deformation can make human body sensory more comfortable, and bottom bending structure strain can make draw runner fixing more firm.
As preferably, said retaining mechanism is a trip bolt, and screw is threaded with slide rail, and screw screws and gets into chute and hold out against draw runner and realize that draw runner fixes.
As preferably, the mating surface of said screw front end face and draw runner and screw is provided with the pattern structure that improves frictional force.
As preferably, said backrest is the tortuous bow structure to human body waist protrusion at waist location, and said backrest is the arc-shaped structure of depression more than waist location.The ergonomic principle.
The present invention cooperates through the slide rail and the retaining mechanism of draw runner backrest top, head rest rear portion rear side, realizes sliding up and down of head rest, and establishes the elastic steel sheet barb on the backrest top, and then head rest is rested the head on the back elastically deformable by the people, makes human body sensory more comfortable.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is further described:
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1; Embodiment for a kind of back of the present invention and head rest syndeton; Head rest 2 rear portions connect a draw runner 3, and backrest 1 top rear side is provided with slide rail 4, is provided with chute in the slide rail; The draw runner bottom is arranged in the chute and can slides up and down along chute, and said slide rail is provided with retaining mechanism draw runner is fixed in the chute.Said backrest top is the crooked barb 13 of side-lower backward, and said slide rail is fixed on the barb, and barb is an elastic steel sheet.Said draw runner is an elastic steel sheet, and said draw runner upper end is the bending structure to front curvature, and said draw runner lower end is a bending structure crooked in barb.Said retaining mechanism is a trip bolt 5, and screw is threaded with slide rail, and screw screws and gets into chute and hold out against draw runner and realize that draw runner fixes.The mating surface of said screw front end face and draw runner and screw is provided with the pattern structure that improves frictional force.Said backrest is the tortuous bow structure 11 to human body waist protrusion at waist location, and said backrest is the arc-shaped structure 12 for caving in more than waist location.
