A system for closing an opening, the system comprising - a scissor-type guide comprising a fixed first end and a free, second end (20") which may be extended away from and retracted towards the first end in a first direction (D 1); - a tilt bracket; - a plurality of lamellae, each lamella having an elongate plate shape extending in a second direction (D 2) perpendicular to said first direction (D 1), each lamella being rotatably connected to said scissor-type guide, and the lamellae being guidable by the scissor-type guide in the first direction (D 1) between - a retracted position adjacent to said fixed, first end of the scissor-type guide, and - an extended position, where said lamellae are distributed along the fixed distance between said first end of the scissor-type guide and the tilt bracket; - a conveyor configured to extract and contract the scissor type guide in said first direction (D 1); - a tilt rail configured for tilting said lamella between an open state and a closed state; - a curved first guide surface formed in or on said tilt bracket; and - a tilt lever connected to said free, second end (20") of the scissor-type guide, to the tilt rail and to the conveyor; characterised in that - the tilt bracket is arranged spaced apart from the first end at a fixed distance in the first direction (D 1); - the tilt lever comprises a guide member; and - said system is configured for bringing the guide member into contact with the curved guide surface, whereby the guide member engages the curved guide surface and is translated in a third direction (D 3), which is perpendicular to both said first direction (D 1) and said second direction (D 2), such that the tilt lever is rotated and translates the tilt rail in the third direction to rotate the lamellae. - a scissor-type guide comprising a fixed first end and a free, second end (20") which may be extended away from and retracted towards the first end in a first direction (D 1); - a tilt bracket; - a plurality of lamellae, each lamella having an elongate plate shape extending in a second direction (D 2) perpendicular to said first direction (D 1), each lamella being rotatably connected to said scissor-type guide, and the lamellae being guidable by the scissor-type guide in the first direction (D 1) between - a retracted position adjacent to said fixed, first end of the scissor-type guide, and - an extended position, where said lamellae are distributed along the fixed distance between said first end of the scissor-type guide and the tilt bracket; - a retracted position adjacent to said fixed, first end of the scissor-type guide, and - an extended position, where said lamellae are distributed along the fixed distance between said first end of the scissor-type guide and the tilt bracket; - a conveyor configured to extract and contract the scissor type guide in said first direction (D 1); - a tilt rail configured for tilting said lamella between an open state and a closed state; - a curved first guide surface formed in or on said tilt bracket; and - a tilt lever connected to said free, second end (20") of the scissor-type guide, to the tilt rail and to the conveyor; - the tilt bracket is arranged spaced apart from the first end at a fixed distance in the first direction (D 1); - the tilt lever comprises a guide member; and - said system is configured for bringing the guide member into contact with the curved guide surface, whereby the guide member engages the curved guide surface and is translated in a third direction (D 3), which is perpendicular to both said first direction (D 1) and said second direction (D 2), such that the tilt lever is rotated and translates the tilt rail in the third direction to rotate the lamellae.
