Abstract
An step assembly (10) is described having a step (12) that moves between down and up positions by pivoting about a longitudinal axis connected to a vehicle chassis (24). One or more link assemblies (22) move the step between these positions. A support bracket (20) connects to the chassis and pivotally supports the step. The link assembly includes a first link (32) having one end fixedly attached to a drive shaft (14) in a radial manner and another end rotatably connected to a second link (34). The connection between the first and second links is located outward of the pivotal connection between the step and the support bracket. In one embodiment, in the up position, the point of rotation between the first and second links is located outward of the drive shaft axis of rotation. A stop is available to limit further rotational travel by the first link.
