Abstract

A ramp assembly provides a transition surface from a vehicle interior to an alighting surface. The ramp assembly includes a ramp portion that rotates between a stowed position and a deployed position. A panel is coupled to the ramp portion about a first axis. The ramp assembly further includes a linkage that is coupled to the ramp portion. An actuator is coupled to the linkage to move the ramp portion through a deployment motion. The deployment motion includes a first phase during which the linkage rotates the ramp portion about the first axis. During a second phase of the deployment motion, the linkage moves the first axis from a raised position to a lowered position.
