[0013] Preferably, the support backrest comprises a fixed plate, the bottom side of the fixed plate is connected with one side of the connecting plate through bolts, the inside of the connecting plate is inserted with a threaded rod, the outer wall of the threaded rod is in sliding contact with the inside of the fixed plate, the other end of the threaded rod is rotatably connected with the inside of the adjusting plate, the outside of one end of the threaded rod is sleeved with a first spring, and the outside of the adjusting plate is covered with a soft bag, when the back of a user is supported, the back of the user will apply pressure to each adjusting plate to a certain extent, each adjusting plate can be in close contact with the back of the user under the action of the spring, each adjusting plate can better support the back of the user, and thus the backrest of the office chair can be adaptively supported according to the shape of the spine of the user.

[0014] Preferably, the top end and the bottom end of the soft bag are smooth in surface, and the soft bag is arranged in a straight line and at equal intervals from top to bottom, a plurality of adjusting plates are arranged to support the back of the user, and each adjusting plate can correspond to different areas of the back of the user, thereby supporting the back of the user.

[0015] Preferably, the surface of the other end of the threaded rod is provided with threads, and the threaded rod is connected with a knob through the threads on the outer wall, the knob is closely attached to the surface of the fixed plate, the knob can drive the threaded rod to move backward by rotating the knob, thereby further compressing the spring, and the pressure of the spring can be adjusted.

[0016] The utility model provides a kind of self-adapting support ergonomics office chair.It has the following beneficial effects:

[0017] (1) This is an adaptive support ergonomic office chair. The design feature of this office chair is that its backrest is integrated with multiple adjustment plates. These adjustment plates can independently correspond to and support different areas of the user's back. When the user sits down, the pressure exerted by the back on the adjustment plate will cause the adjustment plate to fit the user's back curve through the force of the built-in spring. This design enables the adjustment plate to be adaptively adjusted according to the natural shape of the user's spine, thereby achieving personalized support and significantly improving the comfort and support effect of the office chair.

[0018] (2) This adaptive support ergonomic office chair applies a rotational force to the hand rest, and the meshing structure at the bottom of the rotating rod can move upward along the slopes on both sides of the meshing teeth at the top of the support rod, thereby disengaging from the top of the support rod and allowing the angle of the hand rest to be adjusted. When adjusted to a suitable angle, the force of the second spring pushes the rotating rod downward, so that the bottom of the rotating rod re-engages with the top of the support rod, fixing the angle of the hand rest, thereby enhancing the adjustability of the office chair hand rest and allowing the user to adjust the position of the hand rest according to personal needs to obtain a more comfortable use experience.

[0019] This solves the problem that the backrest of the existing office chair cannot be adaptively adjusted according to the spine shapes of different users, thereby reducing the comfort of the backrest. BRIEF DESCRIPTION OF THE DRAWINGS
