Device for closing off an opening made in a structural element comprising synchronization, and corresponding automobile

A device for closing off an opening made in a structure having an interior, comprising a fixed panel in which there is defined an aperture, and at least one sliding panel having:

• an upper shuttle and a lower shuttle, respectively guided in two distinct guide rails mounted or formed on a surface of said fixed panel, wherein the shuttles are disposed toward the interior of said structure;
• a frame bearing at least two guiding pegs respectively engaging with each one of said shuttles, these shuttles comprising guides for guiding said pegs enabling a transverse movement of said frame relative to said shuttles;
• means for actuating acting directly or indirectly on said shuttles in order to move the latter in said rails, causing said sliding panel to move in a direction perpendicular to a plane of said fixed panel;
• and
• means for synchronizing the movement of said shuttles, said means for synchronizing comprising at least one leaf spring or at least one cable circulating in a part of the frame of the sliding panel, and wherein said means for synchronizing is connected to the lower shuttle and to the upper shuttle.
