<p>The cover has a telescopic cover unit with a set of cover elements, where one of the cover elements has a damping unit (1). The damping unit has a retaining plate (10) that is connected with a side wall of the cover element. An arm (2) is pivotable around an axis (5), and is engaged to a stop of adjacent cover elements. A damping element (4) e.g. multi-disk brake or hydrodynamic brake, is fastened to the retaining plate, and exerts braking torque during pivoting of the arm on the axis. An end region of the arm is provided with a sliding element and a roller (7).</p> |
