[0002] At present, the headrests used in chairs are generally fixed, or can only be upgraded and adjusted, such as Chinese patents: ZL201310637445.6, ZL201310266379.6, ZL201320696925.5. The limitation is that the headrest always moves with the back of the chair, while the back of the chair Usually the angle with the cushion is greater than 90 degrees. When the normal working posture of sitting upright (the human waist is separated from the back of the chair) is adopted, the head of the human body cannot get the support of the headrest to reduce the stress on the cervical spine, which may lead to cervical pain over time. greatly increase
