Abstract: A bone plate system having a retainer for resisting back-out of a bone anchor from a throughbore of a bone plate is provided. In one aspect, a bone plate system having a resilient retainer disposed in a bone plate throughbore with a pair of elongate arm portions of the resilient retainer extending along opposite sides of the throughbore. In another aspect, a bone plate system having a resilient retainer with a pair of elongate interference portions completely exposed in the throughbore and spaced from each other across the throughbore to retain a head of a bone anchor received in the throughbore. In addition, a bone plate system having a resilient retainer with a pair of opposite end portions disposed within a groove of a throughbore wall such that a bone anchor may be inserted into the throughbore without contacting either of the opposite end portions of the retainer.

Abstract: A method for rotationally coupling a first member (12) and a second member (14). In a first step, a first member (12) and a second member (14) are provided with one of the first member (12) and the second member (14) including a portion having cutting edge(s) extending therealong. The second member (14) defines an orifice (14a) for receiving therein at least a portion (12a) of the first member (12).

Abstract: A ball assembly (118) for a tripot-style joint includes an annular outer ball (124) having a central axis (L) extending therethrough and a depression (182) formed therein. A plurality of needle rollers (122) is positioned along an interior of the outer ball (124). A needle roller retainer (140) is provided for retaining the needle rollers (122) within the outer ball (124) during operation of the ball assembly (118). The retainer (140) has a base portion (142) axially opposed to an end portion (121) of the needle roller (122), and a flange portion (144) extending from the base portion (142) into the depression (182), the flange portion (144) of the retainer (140) being resiliently pivotable within the depression (182) in response to application of an axial load to the retainer (140). In a particular embodiment, an inner ball (120) is positioned in the interior of the outer ball (124f), and a series of resilient tabs (148f) extends from the base portion (142f) of the retainer (140f).

Abstract: A stroking constant velocity universal joint assembly is provided including a drive member having a plurality of circumferentially spaced rotatable drive elements, and a drive housing disposed about the drive elements. The drive housing has an inner wall formed with a plurality of circumferentially spaced drive channels. The drive channels have running surfaces extending axially of the housing to an open end thereof and which guide the rotatable drive elements for stroking movement within the drive housing. A retainer assembly is provided including a ramped surface extending along each drive channel for gradually narrowing a span of the drive channel, to maintain a respective drive element within the housing. In another aspect of the invention, a retainer assembly is provided for retaining a drive member within a drive housing of a stroking universal joint. The retainer assembly includes a base portion and a plurality of ears projecting from the base portion.
