The chair back 22 is equipped with height of headrest regulating mechanism between the chair back 22 and headrest 3, the back side of the chair back 22 is offered along 22 height side of the chair back
To the straight slot 221 of extension, the both sides back side of straight slot 221 is equipped with the multiple first gear slots 222 extended along back height direction, adjusts
Section component includes 3 mutually fixed handle components 4, screens block 5 and setting on the briquetting 6 at the chair back back side, handle component 4 with resting the head on
There is the first convex slope 41, the convex block 52 that screens block 5 is integrally formed with the second convex slope 51 and coordinates with the first gear slot 222,
The cavity 61 being moved forward and backward for screens block 5 is equipped in briquetting 6；Upper lifting hand component 4, the second convex slope 51 are oblique in the first protrusion
It is moved to the rear portion of cavity 61 under the action of face 41, convex block 52 leaves the first gear slot 222, and handle component 4 can pull headrest 3 to arrive
The proper height of the chair back 22.
The (the first back-moving spring 62 for applying ejecting force to screens block 5, knob group are equipped with as shown in Fig. 2-Figure 12, in cavity 61
After 4 pulling force of part releases, the first convex slope 41 is separated from each other with the second convex slope 51, and the active force of (the first back-moving spring 62 will
To being pushed forward, the convex block 52 on screens block 5 is embedded into the corresponding first gear slot 222 of the chair back 22 screens block 5, makes headrest 3
It is fixed in the position of the chair back 22.
As shown in Figures 2 and 3, second back-moving spring 42, second back-moving spring 42 are equipped between handle component 4 and headrest 3
One downward active force is applied to headrest 3, under the active force, the first convex slope 41 on handle component 4 and screens block 5
On the second convex slope 51 separation.When not pulling handle component 4, the active force of (the first back-moving spring 62 pushes screens block 5,
Convex block 52 and the first gear slot 222 on screens block 5 is set to coordinate, as shown in figure 4, headrest 3 is fixed on certain of the chair back 22 at this time
On a specific gear.
As shown in figure 5, briquetting 6 is equipped with the guide post 63 for ensureing 5 linear movement of screens block.To ensure the straight line of screens block
Movement locus, screens block is under the action of the spring or screens block can be moved forward and backward under the ramp effect of handle component.
