Abstract

A ramp assembly includes a ramp platform movable for reciprocating motion between a stowed position and a deployed position. The ramp platform has an inner ramp panel, an intermediate ramp panel slidably associated with the inner ramp panel, and an outer ramp panel rotatably associated with the intermediate ramp panel. Movement of the ramp assembly from the stowed position to the deployed position defines a deployment motion that includes (1) rotation of the outer ramp panel through at least 90 degrees relative to the intermediate ramp panel; and (2) translation of the intermediate ramp panel relative to the inner ramp panel. A drive assembly is associated with the ramp platform, the drive assembly being movable to reciprocate the ramp platform between the stowed position and the deployed position.
