Claim:
A plastic headrest sleeve for receiving a headrest rod, said headrest sleeve comprising: a tube having top and bottom ends, wherein a wall of the tube comprises at least one resilient clamping segment between the top and bottom ends; a flange at the top end of the tube; a slider that is supported by the flange and displaceable between a position locking the headrest rod and a release position, a drive element; and a helical spring that is mounted on an outside of the tube and automatically biases the resilient clamping segment into an inside of the tube, one end of the helical spring being connected to the drive element and the other end of the helical spring being affixed to the tube; wherein the drive element is displaceably supported on the tube and is operationally connected to the slider and the resilient clamping segment in such a manner that spring action of the helical spring on the resilient clamping segment is reduced or eliminated when the slider is displaced into the release position.
