Abstract: When moving a head rest front portion (12) in a full-open position direction, an ECU (20) determining that the head rest front portion (12) comes close to an occupant head portion on the basis of a detection result of an electrostatic capacitance sensor (14) so as to stop the head rest front portion (12) determines that the head rest front portion (12) 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 (14). Alternatively, the ECU (20) determines that the head rest front portion (12) comes close to the occupant head portion on the basis of a change amount of the electrostatic capacitance value of the electrostatic capacitance sensor (14).

Abstract: A headrest device includes a fixed base, a movable base disposed forward relative to the fixed base, at least one first link being rotatably supported by a connecting shaft provided between the movable base and the fixed base, at least one second link being supported by the connecting shaft so as to rotate relative to the first link, a connection portion connecting the movable base and the fixed base to be relatively movable by a relative rotation between the first link and the second link, a drive portion relatively rotating the first link and the second link in a direction so as to deploy the movable base away from the fixed base on the basis of a detected result by a rear-end collision detection means, and at least one relative rotation restricting portion provided for restricting a relative rotation between the first link and the second link about the connecting shaft.

Abstract: It is an object of this invention to provide an active headrest which will not over-push the head of a passenger. For this purpose, the invention provides a headrest controller for moving a part (20A) or whole of a headrest (20) of a vehicle seat toward a head of the passenger to reduce the distance between the headrest (20) and the head in the horizontal direction by predicting or detecting a crash to the rear of the vehicle, including a head position detecting unit (11) for detecting a predetermined state of approach or state of contact of the headrest (20) to or with the head during the movement of the headrest (20) and a control circuit for stopping the headrest based on a detection signal from the head position detecting unit (11).
