ABSTRACT:
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 vertically and back and forth relative to the vehicle seat, a head detecting device provided to the head support portion so as to detect a clearance between the passenger head and the head support portion and to generate a control signal representative of the detected clearance, and a controller that can control the moving mechanism. The controller controls the moving mechanism so as to move the head support portion to a first proximity position in which the head detecting device may have a predetermined sensitivity relative to passenger head if the head support portion does not reach the first proximity position. The controller further controls the moving mechanism based on the control signal from the head detecting device so as to move the head support portion to a second proximity position which corresponds to an optimal proximity position relative to the passenger head.
