Background art:

with the development of society, people continuously pursue better living conditions and the living pressure is continuously increased, so that the number of people who work for a long time is increased year by year, and the sitting posture becomes the most common posture of modern professional people. The investigation shows that the forward sitting posture time accounts for the longest, but the biomechanical distribution of the lumbar vertebra and the cervical vertebra of the human body is not reasonable when the person sits for a long time in the forward sitting posture, and the poor sitting posture can cause great damage to the waist and cause great load to the lumbar vertebra and the cervical vertebra. Therefore, more and more office workers have lumbar and cervical diseases, such as lumbar disc herniation, lumbar hyperosteogeny, lumbar muscle strain, cervical spondylosis and the like. Therefore, special office aids are needed to relieve the load on the waist and neck in a sitting position to alleviate the discomfort problem of sedentary sitting.

The existing products capable of supporting the waist are also available in the market, generally a filling structure is adopted to be placed on the waist and back of the seat, the waist is close to the natural bending form of the spine of the human body and the stress of the lumbar of the balance part is realized through a front convex structure, however, when the human body is in a forward-leaning sitting posture, most of the existing lumbar support products cannot follow the forward leaning of the human body and continue to maintain the correct sitting posture, the product utilization rate is low, and no obvious effect of reducing the load of the waist is realized. The existing neck support and traction devices require special seats or suspension conditions and cannot be generally combined with office chairs.
