Abstract
A deployable ramp assembly including a fixed ramp portion and a pivotable ramp portion connected thereto through a direct pivot connection to pivot between stowed and deployed positions defined at a first angle from one another, a cover member pivotally connected to the fixed portion to pivot between closed and opened positions defined at a second angle from one another which is substantially smaller than the first angle, a drive assembly pivoting the cover member between the closed and opened positions, and a multiplier assembly interconnecting the pivotable portion and the cover member to transfer the pivoting motion of the cover member to the pivotable portion in an amplified manner, the multiplier assembly bringing the pivotable portion in the stowed position when the cover member is in the closed position and the pivotable portion in the deployed position when the cover member is in the opened position.
