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 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.
