<p>An actuation system for a canvas for covering (20) an open topped body (12) is described, comprising centerings (16) sliding with its own feet (17) at the top of the side panels (14) of the body to support and open out/pack the covering canvas, and means for moving the centerings above the side, panel so as to open out/pack the covering canvas. The movement means comprise a set of rigid elements, operatively coupled with one another and with a set of centerings, configured so as to form a flat kinematic chain suitable for pulling the centerings, wherein the rigid elements are connected so that, by actuating at least one of them, the motion is transmitted to all the centerings of the group and/or to the remaining rigid elements making the centerings of the set come closer together or spread apart.</p> |
