Abstract
It is an object of this invention to provide an active headrest which will not over-push the head of a passenger. For this purpose, the invention provides a headrest controller for moving a part (20A) or whole of a headrest (20) of a vehicle seat toward a head of the passenger to reduce the distance between the headrest (20) and the head in the horizontal direction by predicting or detecting a crash to the rear of the vehicle, including a head position detecting unit (11) for detecting a predetermined state of approach or state of contact of the headrest (20) to or with the head during the movement of the headrest (20) and a control circuit for stopping the headrest based on a detection signal from the head position detecting unit (11).
