Back of the chair subassembly 3 including can dismantle connect in the support 31 of seat 2, connect in the lift adjustment device 32 of support 31, with the back of the chair 33 that lift adjustment device 32 is connected, by back of the chair 33 is kept away from the headrest 34 that one side of seat 2 extends the formation and is fixed in the waist pillow 35 of support 31.

In this embodiment, the seat plate 2 can be clamped at different heights of the bracket 31 to adjust the heights of the waist pillow 35 and the seat back 33.

The chair back component 3 is detachably connected to the seat plate 2 through the bracket 31.

The lifting adjusting device 32 is fixedly connected with the chair back 33 and connects the chair back 33 to the bracket 31. The lifting adjustment device 32 slidably connects the seat back 33 to the bracket 31. The lifting adjusting device 32 is used for controlling the backrest 33 to move along the extending direction of the bracket 31 so as to adjust the position of the backrest 33 relative to the seat plate 2.

Referring to fig. 5-7, fig. 5 is an enlarged view of portion B of fig. 4; FIG. 6 is an exploded view of a portion of the perspective structure of FIG. 3; fig. 7 is a schematic view of the position relationship among the lifting adjusting device 32, the bracket 31, the lumbar pillow 35 and the chair back 33 of the chair back assembly 3 according to the embodiment of the present invention, in which the lifting adjusting device 32 is a schematic perspective view. Specifically, the lifting adjusting device 32 includes a lifting fixing member 321 fixed to the bracket 31, a lifting elastic member 322 fixed to the seat back 33, a lifting movable pressing block 323 fixed to the seat back 33, and a lifting fixed sliding groove 324 fixed to the bracket 31.

The lifting fixture 321 is provided with a plurality of gear grooves 3210 arranged in sequence along the moving direction of the seat back 33 and a fixing groove 3211 arranged along the moving direction of the seat back 33. The seat back 33 slides along the lifting fixing member 321 and is clamped in any one of the gear slots 3210 through the lifting elastic member 322 to adjust the position of the seat back 33 fixed on the bracket 31. This structure makes and lets the user in the use, can be according to the height of self height adjustment back of the chair, again can be according to the user lean on, the dynamics automatically regulated of lying back of the chair 33 position makes back of the chair 33 and human synchronous motion reach the best laminating of back of the chair 33 and human has effectively solved the back and has supported not enough, the back space scheduling problem of facing backwards.

Specifically, the working process of the lifting adjusting device 32 is as follows: when the chair back 33 is adjusted upwards, the lifting elastic piece 322 jumps to the inside of the gear groove 3210, the lifting elastic piece 322 is hooked at the gear position of the gear groove 3210 and stops, at this time, the chair back 33 raises the gear position of one gear groove 3210, and so on, when the gear position is raised to the maximum gear position of the gear groove 3210, the chair back 33 is lifted, the lifting elastic piece 322 stops and the lifting elastic piece 322 resets, at this time, the chair back 33 can slide down to the lowest original gear position of the gear groove 3210 from the highest position, so as to repeatedly realize the height adjustment of the lifting adjusting device 32.

The lifting movable pressing block 323 is clamped in the fixing groove 3211 to lock the lifting elastic member 322 and one of the gear grooves 3210 in which the lifting elastic member 322 is clamped. The arrangement of the lifting movable pressing block 323 is beneficial to improving the reliability of the chair 100.

The lifting movable pressing block 323 and the lifting elastic element 322 are fixed at an interval on one side of the seat back 33 close to the bracket 31, and the fixing groove 3211 is parallel to the gear groove 3210. The lifting movable pressing block 323 and the lifting elastic member 322 can move simultaneously, and when the lifting elastic member 322 is clamped in any one of the gear slots 3210, the lifting movable pressing block 323 is clamped in the fixing slot 3211 for locking.

In this embodiment, the lifting movable pressing block 323 includes two, the fixing grooves 3211 include two, and the gear groove 3210 is alternately interposed between the two fixing grooves 3211. This structure is advantageous in improving the reliability of the chair 100.

The lifting fixing sliding groove 324 extends along the moving direction, and the chair back 33 is connected with the lifting fixing sliding groove 324 in a sliding manner. In this embodiment, a sliding wall (not shown) inserted into the lifting fixing sliding groove 324 is formed by protruding one side of the chair back 33 close to the lifting fixing sliding groove 324. The sliding wall is slidably connected with the lifting fixing chute 324. Of course, the present invention is not limited to this, and other sliding structures may be implemented, for example, a sliding guide rail and a slider that slides along the sliding guide rail are provided inside the fixed lifting chute 324, the sliding guide rail is fixed to the bracket 31, and the slider is fixed to the seat back 33. The lifting fixing sliding groove 324 is provided to improve the reliability of the chair 100 and to improve the user experience.

Preferably, the two lifting fixing sliding slots 324 are included, and the two lifting fixing sliding slots 324 are respectively disposed on two opposite sides of the lifting fixing member 321 along a direction perpendicular to the moving direction. The two lifting fixing chutes 324 prevent the chair back 33 and the lifting fixing chute 324 from sliding and causing the chair back 33 to move in a deviated direction due to unbalanced external force, thereby improving the reliability of the chair 100 and making the user experience good.

The backrest 33 is for supporting the back of the user. In this embodiment, the shape of the chair back 3 conforms to the human engineering principle, and the arrangement of the shape structure enables the user to experience good feeling.
