<p>The cover (1) has a multi-joint (11) e.g. four-joint, arranged at a distance to an insert (2) in a longitudinal direction of the cover, where the cover is transferable from a closing position into an opening position by the multi-joint under the influence of a driving device i.e. worm drive. The driving device blocks the multi-joint in the closing position. The multi-joint has a dead center zone for locking the cover in the closing position, where a movement of the cover is blockable in a longitudinal direction (L) and/or in a vertical direction of the cover in the closing position.</p> |
