Description

A seat back with good support technical field

The utility model relates to the field of seat accessories, in particular to a seat back with good supporting effect.

Background technique

The human spine naturally has four curvatures: neck curvature, thoracic curvature, lumbar curvature, and bottom curvature to reduce the physical stress of the spine during human activities. When a person is in a normal sitting posture, neither the waist nor the back is straight in a straight line. At present, the back of our chair is mostly a linear flat plate, which makes us only have a small part of the waist in contact with the back of the chair when we sit down, and even many people do not touch the back of the chair when they sit down. There is no chair support for the head, and sitting in a sitting position for a long time will make people's waist, shoulders, neck and head very tired, and even cause shoulder and cervical spine diseases. After we sit down, if we want to lean back, we will find that the backrest of the chair does not fit the curve of our back, shoulders and head very well, and the upper body stretches unnaturally, which will increase physical fatigue. The backrest of the chair does not fit the curve of our back, which causes our body to be exhausted and causes shoulder and cervical spine diseases. It is very obvious for office workers and long-distance travelers who need to keep sitting for a long time.

Therefore, there is an urgent need for a seat back with a good supporting effect, which can solve the problem that the existing seat back does not have a comfortable supporting effect.
