Shading Device and Vehicle

A shading device, comprising:

• a shading curtain having a first and a second shading layer, wherein the first and the second shading layer respectively have at least two types of light transmission areas with different light transmission properties;
• and
• a drawing device having a first and a second drawing member, wherein
• the first drawing member is connected to the first shading layer and is configured to draw the first shading layer, and the second drawing member is connected to the second shading layer and is configured to draw the second shading layer,
• the shading curtain is configured to be switchable between a retracted state and a fully deployed state,
• the first and the second shading layer are movable parallelly relative to each other between a first relative position, in which the shading curtain has a first light transmission property, and a second relative position, in which the shading curtain has a second light transmission property,
• the shading device further comprises a reel with a first connection joint with the first shading layer and a reel with a second connection joint with the second shading layer,
• the first and the second shading layer are rolled on the respective reel, and the first and the second shading layer are in the first relative position, in the retracted state of the shading curtain, and
• one of the connection joints is configured to apply an enhanced tensile force on the associated shading layer in the fully deployed state in comparison with in the retracted state of the shading curtain, so that the first and the second shading layer are in the second relative position.
