Claims

[Scope of utility model registration request]

In a seat back/reclining mechanism for a vehicle seat configured to allow the seat back to tilt backwards or stand forward by operating a reclining device, the seat back frame is divided into an upper frame and a lower frame, and the upper frame has its lower end connected to the lower frame. The lower end of the lower frame is tiltably connected to the upper end of the frame, and the lower end of the lower frame is tiltably connected to the rear end of the seat cushion frame. is connected to the upper fulcrum pin and the lower fulcrum pin of the fulcrum pins provided at two upper and lower locations on the upper frame, respectively, by swingable links. Reclining mechanism.
