Technical Field

[0001] The utility model relates to the technical field of adjusting seats, and more specifically, to a back cushion. Background Art

[0002] With the prevalence of the current office working style, many office workers need to sit in the office for a long time, which also makes lumbar and cervical spine diseases common.

[0003] The most common office chairs currently include: a bottom plate, a back plate and a movable support component, and most office chairs have a fixed distance between the bottom plate and the back plate. When a user sits on the chair, leaning the back against the back plate can reduce the pressure of the body on the lumbar spine to a certain extent. However, due to the influence of different groups of people or different sitting postures at different times, there may be situations where the back cannot be leaned against the back plate. The longer the posture is maintained, the more likely it is to cause lumbar spine injury.

[0004] Therefore, it is necessary to design a cushion that is easy to adjust to cope with the situation that the back cannot be leaned against the backboard. Utility Model Content
