The coupling system is arranged between the housing 11 and the plurality of shading blades 12. The coupling system comprises a first rail 131, a second rail 132 and a coupling element 133. The coupling element 133 is for example a rod. The first rail 131 extends along the longitudinal housing direction 3 and the first rail 131 translates along the longitudinal housing direction 3. The second rail 132 extends along the longitudinal housing direction 3. Each of the shading blades 12 is rotatably coupled to the first rail 131 at a first coupling point 121 and each of the shading blades 12 is also rotatably coupled to the second rail 132 at a second coupling point 122. The coupling element 133 is rotatably coupled to the housing 11 and the coupling element 133 is also rotatably coupled to the second rail 132. An actuator translates the first rail 131 along the longitudinal housing direction 3. The coupling element 133 limits a translation of the second rail 132 along the longitudinal housing direction 3, and the shading blades 12 thereby rotate between the closed position 6 and at least one of the open positions 7. Each of the shading blades 12 comprises a strip 221 and a blade holder 222. Each strip 221 extends along the longitudinal blade direction 4, and each strip 221 comprises the second coupling point 122 of the respective shading blade 12. Each blade holder 223 comprises a blade holder body 223, a first blade holder tip 224 and a second blade holder tip 225. Each blade holder body 223 supports the strip 221 along the longitudinal blade direction 4. Each first blade holder tip 224 comprises the first coupling point 121 of the respective shading blade 12. Each second blade holder tip 225 is arranged opposite each respective first blade holder tip 224. In FIG. 5A, the shading blades 12 are arranged partially superimposed, each over the next, with the second blade holder tip 225 of a shading blade 12 partially superimposing the first blade holder tip 224 of the next shading blade 12 along the longitudinal housing direction 4. The shading blades 12 rotate at their first coupling points 121 around a first rotation axis 40 extending along the longitudinal blade direction 4. The shading blades 12 also rotate at their second coupling points 122 around a second rotation axis 41 extending along the longitudinal blade direction 4. In FIG. 5A, the distance from the first coupling point 121 to the second coupling point 122 of each of the shading blades 12 along a traverse direction 5 traverse to the longitudinal housing direction 3 and traverse to the longitudinal blade direction 4 is minimum. In FIG. 5B, the first rail 131 has been slightly translated along the longitudinal housing direction 3. As each of the shading blades is coupled to the first rail 131 and to the second rail 132, when translating along the longitudinal housing direction 3, the first rail 131 causes a translation of the second rail 132 along the longitudinal housing direction 3. In reaction to the translation of the second rail 132 along the longitudinal housing direction 3, the coupling element 133 limits a translation of the second rail 132 along the longitudinal housing direction 3 and the second rail 132 moves along a traverse direction 5 traverse to the longitudinal housing direction 3 and to the longitudinal blade direction 4. The shading blades 12 thereby rotate between the closed position 6 and a first open position 7 in which the shading blades 12 are arranged each spaced from the next along the longitudinal housing direction 3 by an opening formed between the second blade holder tip 225 of a shading blade 12 and the first blade holder tip 224 of the next shading blade 12. In FIG. 5B, the distance from the first coupling point 121 to the second coupling point 122 of each of the shading blades 12 along a traverse direction 5 traverse to the longitudinal housing direction 3 and traverse to the longitudinal blade direction 4 therefore increases with respect to the respective distance in FIG. 5A. Additionally, in FIG. 5B, the distance from the first coupling point 121 to the second coupling point 122 of each of the shading blades 12 along the longitudinal housing direction 3 therefore decreases with respect to the respective distance in FIG. 5A. In FIG. 5C, the first rail 131 has been further translated along the longitudinal housing direction 3. As each of the shading blades is coupled to the first rail 131 and to the second rail 132, when further translating along the longitudinal housing direction 3, the first rail 131 causes a further translation of the second rail 132 along the longitudinal housing direction 3. In reaction to the further translation of the second rail 132 along the longitudinal housing direction 3, the coupling element 133 further limits the translation of the second rail 132 along the longitudinal housing direction 3 and the second rail 132 further moves along the traverse direction 5 traverse to the longitudinal housing direction 3 and to the longitudinal blade direction 4. The shading blades 12 thereby further rotate between the first open position 7 and a second open position 7 in which the shading blades 12 are arranged each spaced from the next along the longitudinal housing direction 3 by an opening formed between the second blade holder tip 225 of a shading blade 12 and the first blade holder tip 224 of the next shading blade 12 larger than the opening of FIG. 5B. In FIG. 5C, the distance from the first coupling point 121 to the second coupling point 122 of each of the shading blades 12 along a traverse direction 5 traverse to the longitudinal housing direction 3 and traverse to the longitudinal blade direction 4 therefore increases with respect to the respective distance in FIG. 5B. Additionally, in FIG. 5C, the distance from the first coupling point 121 to the second coupling point 122 of each of the shading blades 12 along the longitudinal housing direction 3 therefore decreases with respect to the respective distance in FIG. 5B. In FIG. 5D, the first rail 131 has been further translated along the longitudinal housing direction 3. As each of the shading blades is coupled to the first rail 131 and to the second rail 132, when further translating along the longitudinal housing direction 3, the first rail 131 causes a further translation of the second rail 132 along the longitudinal housing direction 3. In reaction to the further translation of the second rail 132 along the longitudinal housing direction 3, the coupling element 133 further limits the translation of the second rail 132 along the longitudinal housing direction 3 and the second rail 132 further moves along the traverse direction 5 traverse to the longitudinal housing direction 3 and to the longitudinal blade direction 4. The shading blades 12 thereby further rotate between the second open position 7 and a third open position 7 in which the shading blades 12 are arranged each spaced from the next along the longitudinal housing direction 3 by an opening formed between the second blade holder tip 225 of a shading blade 12 and the first blade holder tip 224 of the next shading blade 12 larger than the opening of FIG. 5C. In FIG. 5D, the distance from the first coupling point 121 to the second coupling point 122 of each of the shading blades 12 along a traverse direction 5 traverse to the longitudinal housing direction 3 and traverse to the longitudinal blade direction 4 therefore increases with respect to the respective distance in FIG. 5C, and the second coupling points 122 are almost aligned with the respective first coupling points 121 along the traverse direction 5. Additionally, in FIG. 5D, the distance from the first coupling point 121 to the second coupling point 122 of each of the shading blades 12 along the longitudinal housing direction 3 therefore decreases with respect to the respective distance in FIG. 5C. In FIG. 5E, the first rail 131 has been further translated along the longitudinal housing direction 3. As each of the shading blades is coupled to the first rail 131 and to the second rail 132, when further translating along the longitudinal housing direction 3, the first rail 131 causes a further translation of the second rail 132 along the longitudinal housing direction 3. In reaction to the further translation of the second rail 132 along the longitudinal housing direction 3, the coupling element 133 further limits the translation of the second rail 132 along the longitudinal housing direction 3 and the second rail 132 further moves along the traverse direction 5 traverse to the longitudinal housing direction 3 and to the longitudinal blade direction 4. The shading blades 12 thereby further rotate between the third open position 7 and a fourth open position 7 in which the shading blades 12 are arranged each spaced from the next along the longitudinal housing direction 3 by an opening formed between the second blade holder tip 225 of a shading blade 12 and the first blade holder tip 224 of the next shading blade 12 larger than the opening of FIG. 5D. In FIG. 5E, the distance from the first coupling point 121 to the second coupling point 122 of each of the shading blades 12 along a traverse direction 5 traverse to the longitudinal housing direction 3 and traverse to the longitudinal blade direction 4 therefore increases with respect to the respective distance in FIG. 5D, and the second coupling points 122 are almost aligned with the respective first coupling points 121 along the traverse direction 5. Additionally, in FIG. 5E, the distance from the first coupling point 121 to the second coupling point 122 of each of the shading blades 12 along the longitudinal housing direction 3 therefore decreases with respect to the respective distance in FIG. 5D. In FIG. 5F, the first rail 131 has been further translated along the longitudinal housing direction 3. As each of the shading blades is coupled to the first rail 131 and to the second rail 132, when further translating along the longitudinal housing direction 3, the first rail 131 causes a further translation of the second rail 132 along the longitudinal housing direction 3. In reaction to the further translation of the second rail 132 along the longitudinal housing direction 3, the coupling element 133 further limits the translation of the second rail 132 along the longitudinal housing direction 3 and the second rail 132 further moves along the traverse direction 5 traverse to the longitudinal housing direction 3 and to the longitudinal blade direction 4. The shading blades 12 thereby further rotate between the fourth open position 7 and a fifth open position 7 in which the shading blades 12 are arranged each spaced from the next along the longitudinal housing direction 3 by an opening formed between the second blade holder tip 225 of a shading blade 12 and the first blade holder tip 224 of the next shading blade 12 larger than the opening of FIG. 5E. In FIG. 5F, the distance from the first coupling point 121 to the second coupling point 122 of each of the shading blades 12 along a traverse direction 5 traverse to the longitudinal housing direction 3 and traverse to the longitudinal blade direction 4 therefore increases with respect to the respective distance in FIG. 5E, and the second coupling points 122 are almost aligned with the respective first coupling points 121 along the traverse direction 5. Additionally, in FIG. 5F, the distance from the first coupling point 121 to the second coupling point 122 of each of the shading blades 12 along the longitudinal housing direction 3 therefore decreases with respect to the respective distance in FIG. 5E. The rotation between a closed position and the several open positions and vice versa happens continuously and smoothly. According to an alternative embodiment, the rotation happens gradually in stages. According to an alternative embodiment, when the first rail 131 is translated along a direction opposite to the longitudinal housing direction 3, as each of the shading blades is coupled to the first rail 131 and to the second rail 132, the first rail 131 causes a translation of the second rail 132 along a direction opposite to the longitudinal housing direction 3. In reaction to the translation of the second rail 132 along the longitudinal housing direction 3, the coupling element 133 limits the translation of the second rail 132 along a direction opposite to the longitudinal housing direction 3 and the second rail 132 moves along a direction opposite to the traverse direction 5 traverse to the longitudinal housing direction 3 and to the longitudinal blade direction 4. The shading blades 12 thereby rotate between an open position and another open position in which the shading blades 12 are arranged each spaced from the next along the longitudinal housing direction 3 by an opening formed between the second blade holder tip 225 of a shading blade 12 and the first blade holder tip 224 of the next shading blade 12 smaller than the previous opening. Alternatively, the shading blades 12 thereby rotate between an open position and the closed position 6. The distance from the first coupling point 121 to the second coupling point 122 of each of the shading blades 12 along a traverse direction 5 traverse to the longitudinal housing direction 3 and traverse to the longitudinal blade direction 4 therefore decreases with respect to the previous respective distance. Additionally, the distance from the first coupling point 121 to the second coupling point 122 of each of the shading blades 12 along the longitudinal housing direction 3 therefore increases with respect to the previous respective distance. The first rail 131 extends along the longitudinal housing direction 3. In other words, the first rail 131 comprises a first longitudinal axis 47 along the longitudinal housing direction 3. The second rail 132 extends along the longitudinal housing direction 3. In other words, the second rail 132 comprises a second longitudinal axis 48 along the longitudinal housing direction 3.
