ABSTRACT:
A vehicle access ramp especially for wheel chair access includes alternative horizontal and vertical pivot assemblies. A foldable ramp is pivotably attached to a horizontal axis hinge, and vertically pivotable around a vertical rod at a side of a doorway. For deployment to the ground, the ramp is pivoted horizontally and unfolded. To provide access to the doorway without use of the ramp, the folded ramp is locked into its stored vertical position in the vehicle and pivoted or swung out of the way on a vertical pivot assembly in the vehicle doorway.
