Abstract
A ball joint assembly may include a housing having a cavity, a friction seat received within the cavity, and a ball stud having a ball that frictionally contacts the friction seat. In one embodiment, a friction control mechanism moves the friction seat within the cavity to adjust the friction between the ball and the friction seat. In another embodiment, both the cavity and an outer surface of the friction seat may be substantially frustoconically shaped.
