Abstract: A head rest device that improves reliability of detecting a head on the basis of a change in capacitance without complicating a wiring structure. A head rest device is provided with a head rest rear portion configured to be supported to a seat back, and a head rest front portion freely moving forward and backward between a fully-closed position coming close to the head rest rear portion and a fully-open position separated from the head rest rear portion. The head rest front portion is moved by an actuator. The head rest front portion has a sensor electrode structured such that its capacitance is changed as a head of an occupant approaches, and an ECU controlling the actuator so as to move the head rest front portion and detecting the approach of the head of the occupant on the basis of a change of the capacitance of the sensor electrode thereon.

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.

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.
