Abstract: A bearing and a method for making the bearing incorporate annular elastomeric seals that are molded within annular edge grooves of an outer race so as to be bonded thereto while in slidable engagement with an outer spherical surface of a bearing element received within the race. The edge grooves of the race preferably have a relatively rough surface finish in relationship to the outer spherical surface of the bearing element so that there is good bonding of the seals to the race as well as good sealing thereof with the bearing element. Two preferred embodiments each incorporate a lining that is bonded to the outer race prior to a swaging operation which locates the race grooves adjacent the outer surface of the bearing element such that the seals are also bonded to annular edges of the lining during molding within the grooves.

Abstract: A seat recliner of the disclosure includes an adjustment mechanism that adjustably controls the angular orientation of a seat back relative to an associated seat cushion and also includes a latch that releases the seat back for forward tilting movement to an easy-enter position. Seat back and cushion arms are pivotally interconnected along the tilting axis about which the seat back moves and are positioned relative to each other thereabout by the cooperable action of the adjustment mechanism and the latch. A positioning member of the adjustment mechanism is pivotally located relative to the seat cushion arm about the axis by a locking dog that is moved between locking and nonlocking positions by the cooperable action of a cam and a cam actuator. Dog movement to a nonlocking position releases the positioning member to permit adjustment thereof and a consequent change in the angular orientation of the seat back.
