<p>The cover has a roller blind web (18) movable to and fro between opening and closing positions, where a loading bay (9) is maximally opened in the opening position and is completely closed in the closing position. The web is brought into an intermediate position, in which the loading bay is partly opened. Linear actuators transfer the web into the intermediate position or from the intermediate position into the closing position, and positive stop units limit the stroke of the actuators. Drive motors are mechanically or electrically operated with same rated speed to drive the actuators.</p> |
