摘要： The invention relates to a headrest for a vehicle seat, comprising a first part; a second part that is able to rotate with respect to the first part; and a control rod for the relative movement between the first part and the second part; wherein the second part comprises an arcuate opening for receiving the rod, the opening comprising cavities; and wherein the rod is movable between an adjustment position in which the rod does not prevent the relative rotational movement between the first part and the second part; and a locked position in which the rod is trapped inside one of the cavities of the opening, thus preventing relative rotational movement between the first part and the second part.
