Abstract

L'invention concerne une rampe pouvant être placée sur une ouverture de porte d'un véhicule, appartenant à un type spécifié dans la partie générale de la revendication 1. L'objectif de l'invention est de créer un mécanisme de commande facile à utiliser et particulièrement fiable, destiné à fermer la trappe (30). A cet effet, les mouvements entre la trappe (30) et l'élément de rampe (11) sont couplés par l'intermédiaire d'un câble tracteur (32), utilisé en tant que mécanisme de commande, une extrémité dudit câble tracteur (32) étant couplé à la trappe (30) et son autre extrémité étant couplée à un élément de guidage (bloc de guidage 40), ce dernier étant monté de manière à pouvoir se déplacer dans un logement (20). L'élément de guidage (bloc de guidage 40) coopère avec une zone de guidage (16) correspondant à l'élément rampe (11), de manière à ce que le câble tracteur (32) se déplace le longe de l'élément rampe (11), seulement sur une distance partielle suffisamment longue pour déplacer la trappe (30), lorsque l'élément rampe (11) est rétracté et déployé.
