A leg rest and a seat back are rotatably mounted at the front and rear of a seat cushion of a passenger seat respectively, and a footrest is mounted on the leg rest in such a manner that it can be extended and retracted. Adjustment of the angle of the seat back and the leg rest, and positioning of the footrest are performed using a seat back actuator, a leg rest actuator, and a footrest actuator. A proximity sensor is provided at the end of the footrest, wherein, when the proximity sensor detects that the footrest is approaching an obstacle, downward rotation of the leg rest is stopped and the footrest is moved backward. When the leg rest or the footrest is moved, the interference of the obstacle such as a baggage with the footrest can reliably be prevented.
