<p>The opening (1) has an apron (2) that passes from a folded position to a deployed position. The apron is guided laterally on U-shaped structure slides. Walls (4, 5) extend at front and back of the apron in the deployed position and define a groove (8) together. Walls are prolonged in a plane (P) of the apron, at a free end, by a sealing tab (7) that supports on the apron in the deployed position. The tab is designed in a form of a joint made of flexible and elastic material.</p> |
