Assembly having two covers (3, 4) for a vehicle roof of a vehicle, wherein - the first cover, for opening by means of a set-out mechanism, can be raised in a region of a rear cover edge and can be displaced in an opening direction over the vehicle roof into an open position; and - the set-out mechanism assigned to the first cover has: -- a drive carriage which can be displaced along the opening direction in a guide rail by means of a drive; -- a set-out lever which is pivotably and displaceably coupled to the first cover; -- a bearing carriage to which the set-out lever is pivotably coupled; and -- a blocking lever which is movably mounted on the bearing carriage and via which the bearing carriage is held in a first state of the blocking lever in a positionally fixed position with respect to the guide rail; wherein - the arrangement is designed in such a way that, starting from a closed position of the first cover, the set-out lever is set out by means of the set-out mechanism during a displacement of the drive carriage and then interacts with the blocking lever during a further displacement of the drive carriage in such a way that the blocking lever is transferred into a second state in which the bearing carriage can be displaced with respect to the guide rail by means of the drive carriage, - the blocking lever has a locking element which secures the blocking lever in the first state, characterized in that - to secure the blocking lever, the locking element engages in a bearing of the bearing carriage. - the first cover, for opening by means of a set-out mechanism, can be raised in a region of a rear cover edge and can be displaced in an opening direction over the vehicle roof into an open position; and - the set-out mechanism assigned to the first cover has: -- a drive carriage which can be displaced along the opening direction in a guide rail by means of a drive; -- a set-out lever which is pivotably and displaceably coupled to the first cover; -- a bearing carriage to which the set-out lever is pivotably coupled; and -- a blocking lever which is movably mounted on the bearing carriage and via which the bearing carriage is held in a first state of the blocking lever in a positionally fixed position with respect to the guide rail; wherein -- a drive carriage which can be displaced along the opening direction in a guide rail by means of a drive; -- a set-out lever which is pivotably and displaceably coupled to the first cover; -- a bearing carriage to which the set-out lever is pivotably coupled; and -- a blocking lever which is movably mounted on the bearing carriage and via which the bearing carriage is held in a first state of the blocking lever in a positionally fixed position with respect to the guide rail; - the arrangement is designed in such a way that, starting from a closed position of the first cover, the set-out lever is set out by means of the set-out mechanism during a displacement of the drive carriage and then interacts with the blocking lever during a further displacement of the drive carriage in such a way that the blocking lever is transferred into a second state in which the bearing carriage can be displaced with respect to the guide rail by means of the drive carriage, - the blocking lever has a locking element which secures the blocking lever in the first state, characterized in that - to secure the blocking lever, the locking element engages in a bearing of the bearing carriage.
