<p>Driving device intended for the displacement in space of a component which can move with respect to a fixed point, characterised in that it comprises a motor (1) driving about its shaft (2) an element (4) which can be wound up, pulling on a movable lifting element (9) connected to a fixed point (22) serving as an anchoring point for the flexible element (4) and sliding, perpendicularly to the axis of the pulley block mechanism thus constituted, in a tubular guide (15) which accommodates it, and compressing a return spring (10) ensuring that the movable element (9) returns to an extended position so that this device operates in pull-mode and without buckling stress. <IMAGE></p> |
