  • Patent number: 12085426
    Abstract: A ramp assembly is provided comprising a ramp that is pivotally movable between a fold-in position and a fold-out position through a neutral position, a drive shaft spaced from an axis of pivot of the ramp in a direction perpendicular to the axis, a drive element transmitting rotational force from the drive shaft to the ramp such that rotation of the drive shaft causes movement of the ramp between the fold-in and fold-out positions, and a spring generating a biasing force by being rotationally tensioned, the spring biasing the drive shaft such that the ramp is biased toward the neutral position when the ramp is in the fold-out position and biased toward the neutral position when the ramp is in the fold-in position. A vehicle incorporating such ramp assembly is also contemplated.
