[0003] The patent number is 201080004302.6, which discloses a backrest adjustment chair for spine protection. An auxiliary backrest for lumbar protection is installed on the inner side of the backrest structure. The backrest and auxiliary backrest adopt a rack and pinion structure. Sliding, so that the auxiliary backrest slides up and down in the same proportion. According to the sitting height of the person sitting on the chair, the height of the backrest and the auxiliary backrest can be reasonably adjusted to effectively protect the spine. The backrest in this invention is designed with a fixed angle. In fact, it is separated from the human back, and the user's sitting habits are different. The auxiliary backrest cannot effectively protect the spine. A single height adjustment function cannot relieve the user's soreness, which is not conducive to the user's use

[0004] The chairs currently on the market have the following disadvantages: 1. The back of the chair cannot provide 90-degree support. , the back of the human body cannot be effectively supported, and the back of the human body is separated from the back of the chair.

2. The rotation of the back of the chair is not on the same axis as the rotation of the human body. Because the back of the chair and the back of the human body are not on the same axis when they rotate backwards, the back of the chair does not fit the back of the human body after rotation, and the supporting parts are misplaced, causing body unwell

3. The rotation of the chair back is not synchronized with the rotation of the human body. The chairs currently on the market are passively adapted to the changes of the back of the human body, rather than the back of the chair changing with the change of the back of the human body.
