Abstract
An awning arm assembly is provided that includes inner and outer arms. A joint is provided that has an axle, e.g., any structure about which rotation can be provided coupled with one of the inner arm and the outer arm and a hollow body disposed about the axle. The hollow-body is coupled with the other of the inner arm and the outer arm. The hollow body is coupled with the axle such that when the outer arm moves relative to the inner arm the angle between the hollow body and the axle (and thereby the inner and outer arms) is adjusted.
