A shading system for covering an underlying space, said shading system comprising: - a housing extending along a longitudinal housing direction; - a plurality of shading blades arranged one after the other along said longitudinal housing direction, each of said shading blades extending along a longitudinal blade direction traverse to said longitudinal housing direction; said shading blades being movable between a closed position thereby covering said underlying space, and at least one open position; - a coupling system arranged between said housing and said plurality of shading blades, wherein said coupling system comprises: ∘ a first rail comprising a first longitudinal axis along said longitudinal housing direction configured to translate along said longitudinal housing direction; ∘ a second rail comprising a second longitudinal axis along said longitudinal housing direction; ∘ wherein each of said shading blades is rotatably coupled to said first rail at a first coupling point and rotatably coupled to said second rail at a second coupling point; and ∘ a coupling element rotatably coupled to said housing and rotatably coupled to said second rail; - an actuator configured to translate said first rail along said longitudinal housing direction; whereby said coupling element limits a translation of said second rail along said longitudinal housing direction, thereby rotating said shading blades between said closed position and said at least one open position; and - a rain gutter extending along said longitudinal housing direction and arranged below said plurality of shading blades. - a housing extending along a longitudinal housing direction; - a plurality of shading blades arranged one after the other along said longitudinal housing direction, each of said shading blades extending along a longitudinal blade direction traverse to said longitudinal housing direction; said shading blades being movable between a closed position thereby covering said underlying space, and at least one open position; - a coupling system arranged between said housing and said plurality of shading blades, wherein said coupling system comprises: ∘ a first rail comprising a first longitudinal axis along said longitudinal housing direction configured to translate along said longitudinal housing direction; ∘ a second rail comprising a second longitudinal axis along said longitudinal housing direction; ∘ wherein each of said shading blades is rotatably coupled to said first rail at a first coupling point and rotatably coupled to said second rail at a second coupling point; and ∘ a coupling element rotatably coupled to said housing and rotatably coupled to said second rail; ∘ a first rail comprising a first longitudinal axis along said longitudinal housing direction configured to translate along said longitudinal housing direction; ∘ a second rail comprising a second longitudinal axis along said longitudinal housing direction; ∘ wherein each of said shading blades is rotatably coupled to said first rail at a first coupling point and rotatably coupled to said second rail at a second coupling point; and ∘ a coupling element rotatably coupled to said housing and rotatably coupled to said second rail; - an actuator configured to translate said first rail along said longitudinal housing direction; whereby said coupling element limits a translation of said second rail along said longitudinal housing direction, thereby rotating said shading blades between said closed position and said at least one open position; and - a rain gutter extending along said longitudinal housing direction and arranged below said plurality of shading blades.
