ABSTRACT:
The invention pertains to a ball-and-socket joint composed of a ball pivot (1) and a joint housing (3), in which the coupling ball (1a), is supported, such that it can be twisted and tilted to a limited extent, by a plastic bearing shell (2). The bearing shell (2) supports the coupling ball (1a) both above and below the equator (1b) of the ball, at least in the region of a bearing surface (2a',2c') in the form of an annular segment of a sphere. In order to create a mountable ball-and-socket joint, which guarantees the creation and retention of defined joint characteristics over the entire service life of the joint, at least the part of the bearing shell (2) supporting the surface of the coupling ball (1a) lying below the equator (1b) of the ball is divided into at least two sections (2a), each hinge delimited by a film hinge (2b), which together form a bearing surface (2a') in the form of an annular segment of a sphere.
