The system has lamellae (2) arranged parallel to each other and interconnected by tension elements, where the lamellae are pivotally mounted at one end. A connector is fastened at front ends of each lamella, and inverted in a cap shape across the lamella front ends. A drawstring (8) and a turning belt (9) are attached to the connector as the tension elements. A retainer is provided at the connector for fastening the belt. The drawstring and the belt are designed as a perforated strip from metal. The lamellae are made from an extruded aluminum profile and an extruded plastic profile. |
