AI Technical Summary

Problems solved by technology

[0002] The child's body is constantly developing and growing. Too high or too low a learning chair will have an adverse effect on the child's physical development, such as bending over, hunchback and myopia. At right angles or slightly less than 90 degrees, if the feet are suspended in the air or the ground is not solid, the center of gravity will fall completely on the thighs and buttocks, which will compress the blood vessels, affect blood circulation, and make the child feel uncomfortable. Correct sitting posture, at the same time easy to fatigue, affecting concentration

[0003] In order to meet the needs of children's healthy learning, people have developed and designed children's learning desks and chairs. The existing children's learning learning chairs and posture correction chairs generally can only meet the functions of the seat. It is one of the necessary functions; at present, most of the seat height and back height adjustment methods for children's learning chairs and posture correcting chairs in the industry are the seat back and the chair frame through the screw method or the external clamping method, which is laborious, although there are hand cranks on the market. The seat height can be adjusted by lifting and lowering, but the lifting and lowering adjustment of the back height still requires the external clamping method; these methods cannot be adjusted manually for younger children
