Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of furniture, in particular to an adjustable lumbar pillow and a combination thereof and a chair adopting the lumbar pillow combination. Background Art
[0002] With the rapid development of society, more and more people often sit in front of computers to work. However, people sitting for a long time are prone to various lumbar diseases. Lumbar pillows are used to support the waist. Lumbar pillows provide comfort when sitting or lying, so as to relieve waist pain and prevent and treat lumbar diseases. The human spine is composed of 7 cervical vertebrae, 12 thoracic vertebrae and 5 lumbar vertebrae. From the side, it looks like an upright S shape, which has the elastic function of supporting the head, neck and back. Different people have different degrees of curvature of the spine. It may also cause abnormal curvature of the spine due to changes in the gap between the spines caused by personal sleeping posture, sitting posture or other bad postures.

[0028] The following is a clear and complete description of the technical solutions in the embodiments of the utility model in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.
[0029] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.
[0030] Example 1
[0031] like Figure 1-Figure 6 As shown in FIG. 1 , the waist pillow structure of the utility model is shown.
