Description

Cervical vertebra correction chair

Technical Field

The utility model relates to the technical field of chairs, in particular to a cervical vertebra correction chair.

Background Art

Chairs that correct sitting posture generally provide the best sitting environment for office workers and students. The incidence of waist pain among sitting workers is increasing year by year. Lumbar pain, back pain, lumbar disc herniation, buttocks and shoulder muscle pain have become common diseases among those who work in sitting positions. The culprit of this phenomenon is the bad sitting posture that we have followed for thousands of years. Bad sitting posture is the culprit that induces waist and cervical spine diseases. Corrective chairs can maintain the correct sitting posture of the human body, relax muscles, smooth blood circulation, improve spinal health, and maintain pelvic curves. They are very beneficial for office workers and students who study at desks for a long time. It can prevent myopia, chest hunchback, and scoliosis in adolescents, reduce sitting discomfort, and improve learning concentration.

The existing referenceable Chinese utility model patent has a grant announcement number of CN205006388U, which discloses a cervical vertebra correction seat and a sitting posture correction seat. By setting a protrusion, it can prevent people from crossing their legs when sitting on the seat, thereby avoiding the distortion and deformation of the female pelvis. By setting a first sensor, a second sensor and a transverse slide, the sensor can be adjusted according to the fatness of the person to achieve the purpose of correcting the sitting posture. By setting a longitudinal slide and a distance sensor, the distance sensor can be adjusted according to the height of the person, so that people can have a correct sitting posture. If the sitting posture is incorrect, the distance sensor will send a signal to the alarm to prompt the alarm that the posture is incorrect, so that the sitting posture can be fully corrected. By setting an inflatable cushion, the head can be close to the inflatable cushion when sitting on the seat, so that our head can be massaged, giving us a happy mood. By setting a massage air cushion, people's backs can be massaged to promote human blood circulation. The utility model is easy to use, simple to operate, and worthy of promotion.
