Abstract
A headrest device includes a fixed base, a movable base disposed forward relative to the fixed base, at least one first link being rotatably supported by a connecting shaft provided between the movable base and the fixed base, at least one second link being supported by the connecting shaft so as to rotate relative to the first link, a connection portion connecting the movable base and the fixed base to be relatively movable by a relative rotation between the first link and the second link, a drive portion relatively rotating the first link and the second link in a direction so as to deploy the movable base away from the fixed base on the basis of a detected result by a rear-end collision detection means, and at least one relative rotation restricting portion provided for restricting a relative rotation between the first link and the second link about the connecting shaft.
