Massage chair, simple back frame rail mechanism and massage chair

Abstract

This invention relates to the field of massage equipment technology, particularly to a simple back frame rail mechanism for a massage chair and a massage chair. A simple back frame rail mechanism for a massage chair comprises a chassis and a back frame movably installed on the chassis, wherein the back frame is as follows: a back rail on which a back rack is installed; and a seat guide rail movably connected to the back guide rail. Additionally, the massage movement is equipped with a guide wheel and a driving gear, wherein the guide wheel includes a first guide wheel and a second guide wheel, and the driving gear is connected coaxially with the first guide wheel and meshes with the back rack. The present invention installs the back frame in a two-stage manner, dividing the guide rail of the back frame into two stages—a back guide rail and a seat guide rail—and hinges them to each other, thereby enabling the back and seat guide rails to be bent, that is, by adjusting the angle of the back frame, it is possible to effectively stretch the user and improve the user experience.
