Abstract: A guide rail is mounted on a frame of a massage chair and contains: a support track, a seat track, and a flexible guiding assembly. An end of the flexible guiding assembly is connected with the support track, and the other end of the flexible guiding assembly is connected with the seat track. The flexible guiding assembly includes multiple flexible modules arranged along the extending path of the guide rail.
