Operable ramp

摘要

An operable ramp is moveable between a lowered stowed position and a raised deployed position. The operable ramp has a ramp panel rotatable about a first axis located at a first end. A support element is slidingly coupled to the ramp panel. The operable ramp further includes a drive assembly comprising an endless loop coupled to an end of the support element. The endless loop has a linear portion and an arcuate portion. During a first phase of deployment, the end of the support element moves upward along the linear portion. During a second phase of deployment, the end of the support element moves along the arcuate portion of the endless loop.

1. An operable ramp moveable between a lowered stowed position and a raised deployed position, the operable ramp comprising:
(a) a ramp panel rotatable about a first axis located at a first end of the ramp panel; (b) a support element slidingly coupled to the ramp panel; (c) a drive assembly coupled to the support element to selectively raise one end of the support element to rotate the ramp panel about the first axis, wherein raising the one end of the support element moves the support element in a first direction relative to the ramp panel; and (d) a side curb slidingly positioned next to the ramp panel and operatively coupled to the support element, wherein movement of the support element in the first direction relative to the ramp panel moves the side curb upward relative to the ramp panel.
