After massaging, the user cannot use the massage chair as an ordinary seat, because the massager protruding from the elastic body will The user leaning against the seat back is partially stressed, resulting in fatigue or injury to the user. Especially in the field of car driver's seat, the driver is easily fatigued after sitting on the driver's seat for a long time, and has an objective demand for massage, but at the same time, under normal driving conditions, the massager protrudes from the elastic body, which is very easy for the driver to operate at high speed. Injuries from acceleration while driving, or fatigue or injury from local force.

In order to solve this problem, those skilled in the art try to construct a retractable massager, which protrudes from the back of the chair during massage, and is controlled to retract into the elastic body when used as a common seat. In order to realize such a structure, it is necessary to establish a channel for the massager to expand and contract. However, such a channel cannot support the back of the human body when the massager retracts the elastic body, and the part that needs to be massaged is often the part that needs the most support.
