When the waist is leaning against it, the support cushion can be deformed to fit the waist to improve the support comfort. A support plate and a traction rope are also set above the chair back. The deformation resistance of the support plate and the pulling force of the traction rope are used to remind the user to maintain a correct sitting posture. The fixed adjustment belt set between the support plate and the chair back flexibly connects the support plate and the chair back to avoid the loss of the support plate and the traction belt. At the same time, the support plate can be directly hung on the back of the chair back when not in use. When in use, just pick up the support plate and the traction belt. It is convenient to use. The movable height of the support plate can also be adjusted by adjusting the connection position at both ends of the fixed adjustment belt to adapt to users of different heights, thereby improving overall flexibility.

[0018] A further beneficial effect is that one or two traction belts can be used, preferably two, so that the upper end of the traction belt can be directly fixed on the support plate, and there is no need to adjust the position between the upper end of the traction rope and the support plate in advance when wearing it.

[0019] A further beneficial effect is that the number of support pads can be one or two, preferably two, so that when the support pad supports the waist, the body can be stabilized by clamping the support pads on both sides.

[0020] A further beneficial effect is that the adjustment channel arranged between the adjustment holes on the chair back can directly drive the threaded adjustment rod and the mounting block to slide and adjust the up and down height and left and right position of the support pad by releasing the threaded adjustment rod through the clamping block and the adjustment nut after the parts are assembled, which is convenient to operate.

[0021] A further beneficial effect is that the upper end of the support plate is magnetically adsorbed and detachable, and a gravity sensor is provided to monitor the bending angle of the back. When the angle exceeds the set range, the user is reminded to straighten his back and maintain a correct sitting posture, thereby assisting the user to maintain a correct sitting posture and develop a correct sitting posture.

[0022] A further beneficial effect is that a palm pad is also provided on the chair surface, which improves the sitting comfort, and the palm pad has a small deformation amount and does not affect the stability of the body support. BRIEF DESCRIPTION OF THE DRAWINGS
