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.

摘要： A step assembly includes a tread and an actuator. The actuator is operably coupled to the tread and configured to selectively reciprocate the tread between a raised position and a lowered position. The actuator is rotatably coupled to the actuator mount, which is slidably coupled to a frame. A spring selectively maintains a position of the actuator mount relative to the frame.

摘要： A counterbalanced ramp assembly includes a ramp portion coupled for reciprocating motion between a stowed position, a deployed position, and a neutral position. First and second elements are operatively coupled to the ramp portion. When the ramp portion moves from the neutral position toward the deployed position, the first element moves a first end of a spring toward a second end of the spring as the second end of the spring maintains a fixed position. When the ramp portion moves from the neutral position toward the stowed position, the second element moves the second end of the spring toward the first end of the spring as the first end of the spring maintains a fixed 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 providing a transition surface between a vehicle floor and an alighting surface is disclosed. The ramp assembly includes a ramp portion that is rotatable between a stowed position and a deployed position. A target operably associated with the ramp portion so that the target reciprocates along a predetermined path when the ramp portion reciprocates between the stowed position and the deployed position. A sensor fitting maintains a fixed orientation relative to a horizontal plane. A sensor is mounted to the sensor fitting such that the sensor senses the target when the ramp portion is in a predetermined position.

摘要： An operable ramp is moveable between a raised position and a lowered position. In the raised position, the operable ramp forms a step. The operable ramp has a first panel rotatably coupled at a first end about a first axis. The first axis moves in a first direction when the operable ramp moves toward the lowered position and in a second direction when the operable ramp moves toward the raised position. The operable ramp further includes a second panel rotatably coupled at a first end to a second end of the first panel. The first panel and the second panel cooperate to provide an inclined surface when the operable ramp is in the lowered position. A linkage is operably coupled to the first panel to selectively rotate the first panel about the first axis.
