Ramp assembly with tilt sensor

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.

1. A ramp assembly for providing a transition surface from a vehicle floor to an alighting surface, the ramp assembly comprising:
(a) a ramp portion coupled for reciprocating movement between a stowed position and a deployed position, the ramp portion being rotatable about an axis associated with a first end of the ramp portion; (b) a target operably associated with the ramp portion, the target reciprocating along a predetermined path when the ramp portion reciprocates between the stowed position and the deployed position, (c) a sensor fitting rotatably mounted about an axis that maintains a fixed position relative to the vehicle floor, the sensor fitting maintaining a fixed orientation relative to a horizontal plane; and (d) a sensor mounted to the sensor fitting, wherein the sensor senses the target when the ramp portion is in a predetermined position relative to the horizontal plane and sends a signal to a controller, the signal indicating that the ramp portion has reached the predetermined position.
