摘要： A step assembly provides access between a lift platform and an alighting surface. The step assembly includes a tread and a panel rotatably connected to the tread about a first axis. An actuator assembly is operably coupled to the panel to selectively move the step assembly between a raised position and a lowered position. In the raised position, the tread is substantially horizontal, and the panel is orthogonal to the tread. In the lowered position, the tread and the panel are substantially parallel and form a predetermined angle with respect to a horizontal plane.

摘要： A ramp assembly includes a ramp portion configured for reciprocating motion between a stowed position, a deployed position, and a neutral position. The ramp assembly includes a counterbalance comprising a lug associated with the ramp portion so that movement of the ramp portion toward the deployed position moves the lug along an arcuate path in a first direction, and movement of the ramp portion toward the stowed position moves the lug along the arcuate path in a second direction. A flexible line is coupled to the lug, and a restraint is fixedly located relative to the stowed position of the ramp portion. A biasing element is associated with the flexible line such that movement of the ramp portion away from the neutral position moves the biasing element compresses a spring disposed between the restraint and the biasing element.

摘要： A ramp assembly provides a transition surface from a vehicle floor to an alighting surface and includes a ramp portion coupled for reciprocating movement between a stowed position and a deployed position. The ramp portion has a cam surface disposed thereon, and a cam follower that engages the cam surface when the ramp portion is in the stowed position to support the ramp portion. The ramp assembly further includes a panel rotatably coupled to a first end of the ramp portion about an axis. An actuator rotates a drive arm to move the ramp portion through first and second phases of a deployment motion. During the first phase, the drive arm rotates the ramp portion about the axis, which maintains a substantially fixed position. During the second phase, the drive arm moves the second axis in a downward direction.

摘要： A ramp assembly includes a ramp platform movable for reciprocating motion between a stowed position and a deployed position. The ramp platform has an inner ramp panel, an intermediate ramp panel slidably associated with the inner ramp panel, and an outer ramp panel rotatably associated with the intermediate ramp panel. Movement of the ramp assembly from the stowed position to the deployed position defines a deployment motion that includes (1) rotation of the outer ramp panel through at least 90 degrees relative to the intermediate ramp panel; and (2) translation of the intermediate ramp panel relative to the inner ramp panel. A drive assembly is associated with the ramp platform, the drive assembly being movable to reciprocate the ramp platform between the stowed position and the deployed position.

摘要： A ramp assembly is suitable for use in a vehicle to provide a transition surface from the vehicle floor to an alighting surface. The ramp assembly includes an inner panel fixedly associated with the vehicle floor and ramp support slidingly associated with the inner panel. The ramp support is reciprocal between (1) a retracted position when the ramp assembly is in a stowed position and (2) an extended position when the ramp assembly is in a deployed position. A ramp portion is rotatably coupled at a first end to a first end of the ramp support. An intermediate panel is coupled to the ramp support and extends from the inner panel to the ramp portion when the ramp assembly is in the deployed position. When the ramp assembly is in the stowed position, the ramp portion extends inwardly from the first end of the ramp support.

摘要： A ramp assembly includes ramp portion coupled for rotational movement between a stowed position and a deployed position. A panel is rotatably coupled at a curbside end to the ramp portion about a first axis. The ramp assembly further includes an elongate drive arm that extends radially from a second axis. The drive arm is operably coupled to the ramp portion and to an actuator. The actuator rotates the drive arm about the second axis to drive the ramp portion through a deployment motion. The deployment motion has a first phase, during which the drive arm rotates the ramp portion about the first axis, and a second phase, during which the drive arm moves the first axis from a raised position to a lowered position.

摘要： A wheelchair lift assembly is provided. The wheelchair lift assembly includes a frame, a platform, and a lift mechanism associated with the frame. The lift mechanism includes a stabilizing arm and at least one lift arm member having a first end connected to the platform. The first end of the lift arm member pivots and translates relative to the platform as the platform is reciprocated between raised and lowered positions. The wheelchair lift assembly also includes a drive assembly. The drive assembly selectively provides a driving force to the lift mechanism without directly providing the driving force to the stabilizing arm.

摘要： A wheelchair lift (100) for a vehicle having a barrier (128) moveable between an access position and a blocking position. The wheelchair lift includes an actuator (152) coupled to the barrier, the actuator adapted to apply an actuation force upon the barrier to move the barrier from the access position to the blocking position. When the barrier is in an unloaded state, the actuation force causes the actuator to move in a first direction resulting in the barrier moving from the access position to the blocking position. When the barrier is in a loaded state, the actuation force causes the actuator to move in a second direction a predetermined amount without causing substantial movement of the barrier.
