A joint assembly has a member disposed within and movable relative to a housing from a first position through an intermediate position to a third position. A bearing member located between the movable member and the housing cooperates with the movable member and housing to provide a relatively low frictional force opposing movement of the movable member from the first position to the intermediate position. The bearing member also cooperates with the movable member and housing to provide a relatively large frictional force opposing movement of the movable member from the intermediate position to the third position. The bearing member preferably is laminated and has inner and outer surfaces formed of different materials. |
