The shade has reinforcements formed by pre-molded pleats (3,4,5) and which extend over the entire width of the shade (10). The protective sheet consists of flat sections (1,2) sloping towards each other alternately at at least one fold-angle. At least two sheet-sections joined together at a first and second fold have a length including a first and second fold-angle when unrolled, and a third fold connecting first and second sections.
