Abstract
A ramp assembly provides a transition surface between a vehicle floor and an alighting surface. The ramp assembly is moveable between a stowed position, a first deployed position, and a second deployed position. The ramp assembly includes a ramp portion coupled for rotational movement and a panel rotatable about a first end. The ramp portion supportingly engages a second end of the panel to elevate the second end of the panel as the ramp portion moves toward the second deployed position. A method of deploying the ramp portion includes the step of rotating the ramp portion until the ramp portion contacts the alighting surface. The method further includes the steps of rotating the ramp portion until the ramp assembly reaches the first deployed position, in which the ramp portion forms a predetermined angle with the panel, and selectively rotating the ramp portion to the second deployment position.
