A protection device for a vehicle interior has a flexible sheet-like structure which is arranged movably between a compactly put-away rest position and an extended functional position and which is connected on the end side transversely to the direction of extension over its width to a dimensionally stable profiled part. The sheet-like structure has a sheet-like section which is extended over its width and is connected extensively and cohesively to a sheet-like section of an outer casing of the profiled part.
