Abstract: 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.

Abstract: A leg rest and a seat back are rotatably mounted at the front and the back of a sea cushion of a motor-driven seat, respectively. A foot rest is mounted on the leg rest so that it can be extended and retreated. Motor-driven actuators each having a potentiometer are individually connected to them. The motor-driven actuators are controlled by a controller in response to an input of an operation switch, based on a position determined by the potentiometer, and in accordance with a predetermined reference position, thereby adjusting the angles and the positions of the seat parts. The motor-driven actuator is temporarily moved to the end of the stroke, so that limit switches are activated, and the reference position is adjusted based on the position determined by the potentiometer, thereby significantly reducing the amount of adjustment work.
