<p>A tensioning device for tensioning a flexible elongate member (17), such as a cord, comprises a first winding member (1,19) which can rotate around an axis (4,13) for, directly or indirectly, winding and unwinding the elongate member (17) at a first end thereof, and a second winding member (5,12) which can rotate around said axis (4,13) for, directly or indirectly, winding and unwinding the elongate member (17) at the second end thereof. The first and second winding members are interconnected by a tensioning member (8,21) striving to cause a relative rotation between the first (1,19) and second (5,12) winding members for creating a prestress in the elongate member (17). Restriction means (2,6) are provided for limiting the maximum possible relative rotation between the first and second winding members.</p> |
