AI Technical Summary
Existing massage chairs have complex backrest and leg support structures, and the separate rack and pinion design affects stability and makes it difficult to achieve simple angle adjustment.
The leg frame and backrest frame are connected by a single guide rail rack and hinge, combined with a pulley and slide rail design, which allows for free adjustment of the leg frame and backrest frame. The leg frame is driven to move in the slide rail by a drive component, which in turn drives the backrest frame to move, simplifying the structure and improving stability.
It enables easy angle adjustment of the massage chair backrest and leg rest, improves structural stability and enhances the user's multi-posture massage experience, while reducing noise and complexity during exercise.
