Abstract
A ball-and-socket joint has a ball shell of basically spherical shape, a ball stud with a ball head integrally formed at an extremity thereof and disposed within the ball shell, and a rubber layer interposed between and joining the ball shell and the ball head. The outer surface area of the ball shell on the distal side, remote from a shank of the ball stud, of an equatorial plane passing through the center of the ball head perpendicularly to the ball stud axis is greater than the outer surface area of the remainder of the ball shell on the other, or proximal, side of the equatorial plane. The rubber layer is, therefore, made thicker at parts thereof calculated to withstand loads transmitted between the ball shell and the ball head.
