phase this makes it clear that by means of winds or by means of wind created by thermal flows the protective skin 2 or the sheets 3 a b c d e is swiveled along the previously described swivel line around the upper edge area of the protective skin 2 or the sheets 3 in the partially swiveled out position according to fig2 openings 6 are created in the protective skin 2 so that atmospheric air can flow through the protective skin 2 this causes especially the effective working area of the protective skin 2 for the wind or the flowing atmospheric air to be substantially reduced so that the protective skin 2 is not adversely affected or torn or even completely destroyed during winds or during a storm this is particularly contrary to prior art whereby respective weather protection devices have a continuous foil or such as the protective skin and they are to resist wind forces by means of comparably complex as stable as possible and multiply stretched protective skins in the case of protective skins according to prior art experience has shown that comparably heavy storms or gusts of wind destroy the same so that for instance the agriculturist experiences substantial financial damages both with regard to the destroyed protection system and with regard to possibly destroyed cherries or such through the use of a comparably simple inexpensive flexible protective skin 2 or.
