Description

Technical Field

[0001] The utility model relates to the technical field of seat lumbar supports, in particular to a rotating and folding lumbar support. Background Art

[0002] When people sit for a long time, the pressure on the intervertebral disc is three times the weight of the torso. If you maintain a sitting posture for a long time, the pressure on the intervertebral disc will gradually accumulate. Initially, it will lead to poor blood circulation in the waist, gradual increase of lactic acid, and soreness and swelling in the waist. If you don't protect it, it will gradually compress the spine, causing lumbar muscle strain and lumbar diseases. Lumbar support can provide good support for the human waist, help relax the waist, and relieve waist pressure. However, when the lumbar support cannot meet the different needs of users with different body shapes for the stability and wrapping of the lumbar support, it is difficult for the lumbar support to effectively relieve waist pressure.
