ABSTRACT:
A running board for an overland vehicle including first and second bell cranks with swing arms which move relative to the vehicle in opposing arcuate displacements. An elongated central running board member is flexibly connected to the swing arms to form a linkage which is extended and retracted. An extension compensator is included to compensate for changes in the overall length of the linkage. A motor-powered drive pivots the swing arms and preferably provides a control mechanism which coordinates the swing arm motions to keep the running board level. The drive can be automatically controlled by a door switch or other sensor.
