Abstract
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.
