Abstract

A pivot joint assembly comprising a first structure (16) having a convex bearing member (32) and a second structure (31) having a bearing surface (30) for cooperation with the convex, bearing member (32) so as to facilitate relative rotation between the first (16) and second (31) structures about at least a first axis. A bias member (24) is provided for biasing the convex bearing member (32) into the bearing surface (30). The bias member (22) acts on the first structure (16) such that the direction of the bias force relative to the bearing surface (30) is substantially the same in all relative po.sitions of the first (16) and second (31) structures.
