A mechanism for deploying and aligning a ramp relative to a platform includes a main bearing operatively associated with the platform and rotatable about a main pivot axis; a drive member disposed on the main bearing, the drive member being adapted to drive the main bearing to rotate about the main pivot axis; a rotating member disposed on the main bearing and rotatable about the main pivot axis with the main bearing; and a ramp member rotatably connected to the rotating member at a pivot point eccentric to the main pivot axis. Rotation of the rotating member causes the ramp member to move between a stowed position and a deployed position in an arcuate path about the main pivot axis.

L'invention porte sur un mécanisme pour déployer et aligner une rampe par rapport à une plateforme, lequel mécanisme comprend un roulement principal associé de façon fonctionnelle à la plateforme et pouvant tourner autour d'un axe de pivotement principal ; un élément d'entraînement disposé sur le roulement principal, l'élément d'entraînement étant apte à entraîner le roulement principal en rotation autour de l'axe de pivotement principal ; un élément rotatif disposé sur le roulement principal et pouvant tourner autour de l'axe de pivotement principal avec le roulement principal ; et un élément de rampe relié de façon rotative à l'élément rotatif en un point de pivotement excentré par rapport à l'axe de pivotement principal. La rotation de l'élément rotatif amène l'élément de rampe à se déplacer entre une position escamotée et une position déployée suivant un trajet arqué autour de l'axe de pivotement principal.
