<p>The protecting device has a flexible flat structure (5), which is provided at opposite longitudinal sides with a side periphery (8). A winding shaft is pivoted with the flat structure, on which the flat structure is winded up and unwinded. Each side periphery of the flat structure is assigned to a deflection guide unit (9). The deflection guide unit transfers traction force components to the side periphery in a force fit and form fit manner. The traction force components are acting outwards transverse to the winding up and unwinding direction of the flat structure.</p> |
