Boot seal for a ball and socket joint

摘要

A ball stud (30) has a ball end (32) received in a socket (60) to form a ball and socket joint (20). A boot seal (10) has a first end portion (82) for encircling and sealingly engaging a portion (78) of the socket (60). The boot seal (10) has a second end portion (84) which defines an opening (94) through which the ball stud (30) extends. The second end portion (84) of the boot seal (10) has portions (140, 150, 160, 170) which permit relative angular movement of the ball stud (30) and the socket (60) in a first direction (A) and block relative angular movement of the ball stud and the socket in a second direction (C).
