Abstract
A ramp assembly provides a transition surface from a vehicle floor to an alighting surface. The ramp assembly includes a ramp portion that rotates between a stowed position and a deployed position. A panel is rotatably coupled to the ramp portion about a first axis. The ramp assembly further includes an actuator that provides a rotational force to the ramp portion that drives the ramp portion through a deployment motion. The deployment motion includes a first phase during which the rotational force rotates the ramp portion about the first axis. The deployment motion further includes a second phase during which the rotational force moves the first axis in a downward direction.
