The backrest is provided with a transversely-arranged rotating shaft. The headrest is rotationally connected with the backrest through the rotating shaft. A plurality of pressure sensors are arranged inside the backrest. When the pressure sensors sense that the backrest pressure is distributed unevenly, the first connecting rod assembly drives the bottom of the headrest to turn over outwards around the rotating shaft. The pressure sensors sense the distribution state of pressure on the backrest, whet
