Abstract: Protection device for a vehicle interior compartment including a flexible planar structure held on a roller blind shaft windable and unwindable between a pulled-out protective position and a compactly stored rest position. The planar structure is connected to a dimensionally stable pull-out profile on a face end region that is in front in the pull-out direction, which profile is guided for longitudinal displacement on each of its opposite sides in a respective guiding structure disposed fixed to the vehicle in the ready-for-use condition. At least one supporting structure is provided for rotatable bearing of the roller blind shaft, wherein the lateral guiding structures are connected to the supporting structure and are pivotably arranged on the supporting structure for an assembly position. Securing elements for releasable fixation of the guiding structures in their assembly position, pivoted towards the supporting structure, are provided on the supporting structure.
