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 control device is constructed to actuate the head rest moving mechanism when the distance between the head rest and the head detected by the sensor is outside of a proper range of clearance in which it is possible to deal with a back-side collision of the vehicle, thereby moving the head rest to a proper position in which it is possible to deal with the back-side collision of the vehicle.

Head rest control systems

A head rest of a vehicle seat may include a head support portion for supporting a head of a passenger, and a drive unit for moving the head support portion. The drive unit has a moving mechanism that is arranged and constructed to move the head support portion toward and away from the passenger head, an actuator for actuating the moving mechanism, a load detecting device that can detect a load applied to the actuator and generate a control signal representative of the detected load, and a controller that can control the actuator so as to control the moving mechanism. The controller controls the moving mechanism so as to move the head support portion toward the passenger head. The controller controls the moving mechanism based on the control signal so as to stop the motion of the head support portion.
