Abstract
A head rest of a vehicle seat may include a main body having a front portion for supporting a head of a passenger and a rear portion that is attached to a head rest stay, a moving mechanism that is arranged and constructed to move the main body or the front portion vertically and to move the front portion back and forth, and a control device that is arranged and constructed to control motions of the moving mechanism. The moving mechanism includes a first moving mechanism for upwardly moving the main body or the front portion and a second moving mechanism for forwardly moving the front portion. The control device controls the motions of the moving mechanism based upon a detection signal that is generated when a vehicle collision is predicted or sensed, so that the second moving mechanism is actuated after the first moving mechanism is actuated.
