Abstract: A bearing-shaft assembly includes a shaft having a first cylindrical section and a second cylindrical section axially separated by a first annular groove. A bearing is arranged around the annular groove and axially overlaps with the first and second cylindrical sections. A first bushing fills a radial gap between the inner race of the bearing and the first cylindrical section. The first bushing has a first radial collar radially overlapping with the inner race and axially overlapping with the first cylindrical section. A second bushing fills a radial gap between the inner race and the second cylindrical section. The second bushing has a second radial collar radially overlapping with the inner race and axially overlaps with the second cylindrical section. The second bushing fills the first annular groove and is made of a softer material than the first bushing.

Abstract: A powered window regulator for use with a horizontally sliding window assembly may be disconnected from a sliding pane to permit manual operation of the window. The regulator has a tubular guide rail mounted adjacent and parallel to the lower edge of the window assembly by pivot brackets which engage the respective ends of the guide rail such that the guide rail is rotatable about the pivot brackets. A carrier block slides within the guide rail, and a portion of the block extends out through a longitudinal slot extending along the length of the guide rail to engage a pane attachment affixed to the sliding pane. The carrier block is moved reciprocally along the guide rail by a motor-driven cable to slide the sliding pane between open and closed positions. Rotation of the guide rail about the pivot brackets through approximately ninety degrees moves the carrier block between an upright position wherein it engages the pane attachment and a depressed position wherein it is disengaged from the pane attachment.

Abstract: A window regulator for use with a horizontally sliding window assembly has a channel-like guide rail, an elongated carrier plate slidingly movable along the guide rail, and a cable drive mechanism for moving the carrier plate along the guide rail. Pane engagement pairs are disposed at opposite ends of the carrier plate, each comprising a male feature and a mating female feature. One of the features of each pair is secured to the carrier plate and the mating feature is secured to the sliding pane adjacent an outboard edge thereof. The male/female engagement between the features allows the sliding pane and the carrier plate to move relative to one another along an axis generally perpendicular to the sliding pane, while the two-point engagement between the pane and the carrier plate serves to stabilize the pane and allow it to slide smoothly even if the guide tracks for the sliding pane and the guide rail are less than perfectly flat and parallel to one another.

Abstract: A window regulator for driving two sliding window panes, such as of a truck rear window, in opposing directions has a housing containing two linear actuator, one driving each of the sliding panes. The first actuator has opposite ends engaged with a drive drum and a midpoint engaged with the first sliding pane, and the second linear actuator has opposite ends engaged with the drive drum and a midpoint engaged with the second sliding panes. The drive drum has two parallel, spiral grooves, one receiving each of the linear actuators. The first and second linear actuators pass around pulleys and guide blocks attached to the housing and follow separate paths within the housing such that rotation of the drive drum in one direction pulls on respective first ends of the first and second linear actuators to draw the sliding panes toward one another, and rotation of the drum in the opposite direction pulls on respective second ends of the linear actuators to draw the panes away from one another.
