Abstract

The articulated joint consists of a spherical ball with a stem which is assembled to pivot in a housing by means of a bearing member made from plastics material having an annular flange supported by a closing washer and provided with a series of slots which subdivide it into petals arranged between the ball and the bottom of the housing. The petals are in the form of wedges and are loaded by elastic elements made of the same material as the spherical ball race and which bear on the annular flange to ensure the preloading and automatic taking up of play.
