ABSTRACT:
A ball and socket joint connects load transmitting members for relative pivotal movement. The ball and socket joint includes a socket, a ball stud, and a deformable elastomeric material. The socket connects with one member. The socket has an opening and a surface defining a chamber. The ball stud connects with the other member. The ball stud has a ball portion and a shank portion extending therefrom. The ball portion is disposed in the chamber and the shank portion extends through the opening. The ball portion includes at least one surface defining a volume therein. The deformable elastomeric material is disposed between the socket and the ball portion of the ball stud to resiliently interconnect the ball stud with the socket. The deformable elastomeric material also urges the ball stud to return to an initial position relative to the socket upon relative movement of the ball stud and socket. The elastomeric material has at least one portion which projects into the volume of the ball portion to mechanically interlock the elastomeric layer and the ball stud. The portion projecting into the volume prevents slippage of the elastomeric layer relative to the ball stud.
