The present invention relates to a light shielding device comprising: a light shielding curtain comprising a first light shielding layer and a second light shielding layer; the traction device comprises a first traction component and a second traction component; the first traction member and the second traction member are movable between a first relative position, in which the shade has a first light transmission characteristic, and a second relative position, in which the shade has a second light transmission characteristic, relative to each other, such that the first light shielding layer and the second light shielding layer move parallel to each other. The shading curtain has a second light transmission property, characterized in that the shading device has a common winding shaft which has a hollow structure and has an opening along the circumferential surface of the winding shaft, through which opening a guide edge is formed, the first light shielding layer is fixedly connected to the inside of the winding shaft via an elastically deformable element and is guided out of the winding shaft through the guide edge, and the second light shielding layer is fixedly connected to the outer peripheral surface of the winding shaft.
本发明涉及一种遮光装置,其包括:遮光帘,其包括第一遮光层和第二遮光层;牵引装置,其包括第一牵引部件和第二牵引部件;第一牵引部件和第二牵引部件能在相对彼此的第一相对位置与第二相对位置之间移动,使得第一遮光层和第二遮光层相对彼此平行地移动,在所述第一相对位置中,遮光帘具有第一透光特性,在所述第二相对位置中,遮光帘具有第二透光特性,其特征在于,该遮光装置具有一个共同的卷绕轴,该卷绕轴具有中空结构并且沿该卷绕轴的周面具有开口,通过该开口形成引导边缘,第一遮光层经由能弹性变形的元件固定地连接在该卷绕轴的内部并且通过所述引导边缘被导出该卷绕轴,第二遮光层与该卷绕轴的外周面固定地连接。
