<p>The drive consists of a pulley wheel (5) for a drive cable (3) that extends on either side of the wheel in two directions, while the wheel is able to move along an axis (6) lying perpendicular to a plane defined by the two directions and about which the wheel rotates. The drive also incorporates a tensioner (9) that adapts to variations in the direction of the cable as the wheel moves along the axis. The tensioner is in three sections (9a, 9b, 9c), the first section rotating about the axis (6), the second one (9b) being flexible and connecting the first (9a) and third (9c) sections, with the latter in the form of a pulley.</p> |
