<p>The device has a transmission unit (10) connecting an unwinding axle to a winding tube (5) and comprising an integrated differential device (11) with an input shaft (12) on which an output drive wheel is rotatably mounted. A unit (14) allows transformation of the rotation of the shaft into a rotation and/or a linear axial displacement of the wheel, for allowing a differential angular rotation of the shaft with respect to the wheel.</p> |
