摘要： A method is disclosed for deploying a ramp assembly. The ramp assembly includes a ramp portion rotatable between a stowed position and a deployed position. The ramp assembly further includes a panel rotatable about a first end, wherein 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 deployed position. The method includes the step of rotating the ramp portion until the ramp portion contacts an alighting surface. The method further includes the step of rotating the ramp portion until one of a first condition and second condition occurs. The first condition is that the ramp portion has reached a maximum slope. The second condition is that the second end of the panel has reached a predetermined elevation.

摘要： An operable ramp is moveable between a stowed position, a neutral position, and a deployed position. The operable ramp includes a ramp panel rotatably coupled at a first end about a first axis and a support that is rotatable in a first direction and a second direction about a second axis. A cam follower is coupled to the support and supportingly engages a second end of the ramp panel. Rotation of the support moves the cam follower along an arcuate path. The weight of the ramp panel biases the support in the second direction when the operable ramp is between the stowed position and the neutral position. A drive assembly selectively rotates the support in the first and second direction, and a stop limits rotation of the support in the second direction when the operable ramp is in the stowed position.

摘要： A counterbalance for a ramp assembly includes a chain assembly and a spring assembly. The spring assembly includes a spring and first and second spring fittings. The first spring fitting restrains a first end of the spring when the ramp portion is between a neutral position and the stowed position and moves the first end of the spring toward a second end of the spring when the ramp portion moves from the neutral position toward the deployed position. The second spring fitting is spaced from the first spring fitting and restrains the second end of the spring when the ramp portion is between the neutral position and the deployed position. The second spring fitting moves the second end of the spring toward the first end of the spring when the ramp portion moves from the neutral position toward the stowed position.

摘要： A ramp assembly for a vehicle having a floor includes a movable floor at least partially disposed within the vehicle. A ramp support element is rotatably coupled within the vehicle. A ramp portion is coupled at a first end to the ramp support element so that the ramp portion reciprocates between a stowed position a deployed position when the ramp support element rotates. A reciprocating mechanism reciprocates the second end of the movable floor between a lowered position when the ramp is in the stowed position, and a raised position when the ramp is in the deployed position.

摘要： An operable ramp is moveable between a raised position, in which the ramp forms a pair of steps, and a lowered position, in which the operable ramp provides an inclined surface. The operable ramp includes a first panel rotatably coupled about a first axis that moves back and forth when the operable ramp moves between the lowered position and the raised position. A link is rotatably coupled to the first panel about a second axis and is itself rotatable about a fixed third axis. A second panel is rotatably coupled to the link between the second axis and the third axis, and a third panel is rotatably coupled to the second panel about a fourth axis. When the ramp moves between the raised and lowered positions, the fourth axis rotates about a fixed fifth axis. A linkage selectively rotates the first panel about the first axis.
