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 integrated fixing structure, and head rest cannot be adjusted.Be difficult to meet different bodily form people's demand.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of back and headrest connecting structure, 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 headrest connecting structure, it is characterized in that: head rest rear portion connects a draw runner, backrest top rear side is provided with slide rail, in slide rail, be provided with chute, draw runner bottom is arranged in chute and can slides up and down along chute, and described slide rail is provided with retaining mechanism draw runner is fixed in chute.
As preferably, described backrest top is the barb portion of side-lower bending backward, and described slide rail is fixed in barb portion, and barb portion is elastic steel sheet.
As preferably, described draw runner is elastic steel sheet, and described draw runner upper end is the bending structure to front curvature, and described draw runner lower end is to crooked bending structure in barb portion.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, described retaining mechanism is a trip bolt, and screw is threaded with slide rail, and screw screws and enters chute and hold out against draw runner and realize draw runner and fix.
As preferably, the mating surface of described screw front end face and draw runner and screw is provided with the pattern structure that improves frictional force.
As preferably, described backrest is the tortuous bow structure of protruding to human body waist at waist location, and described backrest is the arc-shaped structure of depression more than waist location.Meet base of principle of human engineering.
The present invention coordinates by 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 on backrest top, establishes elastic steel sheet barb portion, and head rest is rested the head on upper rear elastically deformable by people, makes human body sensory more comfortable.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is 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 headrest connecting structure, head rest 2 rear portions connect a draw runner 3, backrest 1 top rear side is provided with slide rail 4, in slide rail, be provided with chute, draw runner bottom is arranged in chute and can slides up and down along chute, and described slide rail is provided with retaining mechanism draw runner is fixed in chute.Described backrest top is the barb portion 13 of side-lower bending backward, and described slide rail is fixed in barb portion, and barb portion is elastic steel sheet.Described draw runner is elastic steel sheet, and described draw runner upper end is the bending structure to front curvature, and described draw runner lower end is to bending structure crooked in barb portion.Described retaining mechanism is a trip bolt 5, and screw is threaded with slide rail, and screw screws and enters chute and hold out against draw runner and realize draw runner and fix.The mating surface of described screw front end face and draw runner and screw is provided with the pattern structure that improves frictional force.Described backrest is the tortuous bow structure 11 of protruding to human body waist at waist location, and described backrest is the arc-shaped structure 12 for caving in more than waist location.
