Abstract: When moving a head rest front portion in a full-open position direction, an ECU determines that the head rest front portion comes close to an occupant head portion on the basis of a detection result of an electrostatic capacitance sensor so as to stop the head rest front portion, and determines that the head rest front portion comes close to the occupant head portion on the basis of an absolute capacitance change with respect to a reference electrostatic capacitance value of the electrostatic capacitance sensor. Alternatively, the ECU determines that the head rest front portion comes close to the occupant head portion on the basis of a change amount of the electrostatic capacitance value of the electrostatic capacitance sensor.

Abstract: It is one object of the present invention to provide a control for moving a head rest in response to a signal from a sensor detecting a distance between the head rest and a head of a passenger, in which even if the head of the passenger moves within a predetermined range, the head rest can be prevented from moving depending on the motion of the head of the passenger so as to remove discomfort for the passenger. Therefore, the present invention has a construction as follows. A head rest control system in which a head rest of a seat of a vehicle is constructed to be moved back and forth by a head rest moving mechanism may include a sensor detecting a distance between the head rest and a head of a passenger, and a control device controllably actuating the head rest moving mechanism.

The use of the conductive woven cloth, which is formed with the surface member of the seat, as the detection electrode enables not to degrade the texture of the seat. The threshold time for detecting whether an occupant is seated in a seat or not may be set using a charging time which is measured when no occupant is seated in the seat as the initial value.
