摘要： The invention relates to a height adjustable headrest device with a crossbar element and a headrest supporting element as well as a clamp connection for continuously variable mounting of the headrest element at the crossbar element. The clamp connection comprises a retaining clamp comprising two recesses as well as a tapped bore and gripping around a crossbar element, a centering bushing comprising an external thread and an internal thread, the centering bushing being screwed into the tapped bore of the retaining clamp, as well as a screw element screwed in the centering bushing. The headrest supporting element is inserted in the recesses of the retaining clamp. The crossbar element comprises a bore in which the centering bushing is inserted. The clamp connection is caused by screwing the screw element into the centering bushing and thus bringing the headrest supporting element near the crossbar element.
