1. A vehicle step for access to a vehicle, the vehicle including a chassis frame and a body panel, the vehicle step comprising:
a cam track frame comprising:
a first plate;a second plate, with the first and second plates coupled together in a parallel, space-apart relationship with at least one traverse member;a first cam track defined in each of the first and second plates proximate the traverse member, the first cam track extending from a first end to a second end, with the first cam track defining a curved portion proximate the second end of the track; anda second cam track defined in each of the first and second plates a spaced distance from the first cam track, the second cam track extending from a first end to a second end, with the second cam track defining a downwardly extending portion proximate the second end of the track; and a step assembly configured for guided movement between the first and second plates, the step assembly comprising:
a step frame configured for sliding movement in the cam track frame and having two ends;a step pad coupled to the step frame at one end; anda pair of cam rods disposed proximate another end of the step frame, with each cam rod coupled to the step frame and configured to slidingly engage one of the first and second cam tracks,wherein the step assembly moves between the first and second plate, guided by the cam rods in the first and second cam tracks with the vehicle step coupled to the chassis frame;wherein the second cam track is configured to be located between the first cam track and the body panel of the vehicle; andwherein the first end of the first cam track is configured to be located higher than the first end of the second cam track when the vehicle step is in an installed configuration relative to the vehicle. |
