Abstract
A joint assembly for use in transmitting torque comprises a ball and socket arrangement. The socket is comprised in a housing, and further comprises a key chamber with a substantially regular polygonal profile defining interior faces. The ball is provided on a ball stud component, and has a plurality of convexly curved facets. The ball is inserted in the socket with a plurality of keys, such that the keys are disposed between the ball facets and a corresponding interior face. Each key provides a bearing surface that mates with a corresponding facet, and a surface opposite the bearing surface to mate with the interior face. The sides of the key define a biconvex profile.
