A displaceable head restraint for a seat has a padded portion that is displaceable relative to a base part of the head restraint from a nominal position to a safety position using a driving mechanism and returnable to the nominal position using a restoring device. The restoring device includes a handle releasably connected to a receiver plate, and the receiver plate is positioned on a fixed portion of the base part. A cable having one end attached to the handle and an opposed end connected to a rotatable member is disposed between the padded portion and the base part. Application of a force on the handle that is opposed to a direction of displacement of the padded portion between the nominal position and the safety position rotates the rotatable member to return the padded portion to the nominal position.
