Shading blind for a roof window of a motor vehicle

A shading blind for a roof window of a motor vehicle having two guide rails, a roller blind element which has two lateral, flexible guide structures with which it is guided in the guide rails, and a receiving space for the roller blind element, the roller blind element being adjustable between an extended position in which it is largely located outside the receiving space, and a retracted position in which it is largely located in the receiving space, wherein the receiving space has a length which is approximately half of the adjustment path between the extended and the retracted positions, the height of the receiving space is such that when the roller blind element is deflected in the receiving space by approximately 180°, the guide structures are only elastically deformed and a rear edge of the roller blind element is permanently attached in the receiving space.
