Stabilizing mechanism for the rear end of a raised vehicle window includes a stabilizer track mounted in the door and including a vertical upper portion and a forward curving lower portion. A stabilizer link has a lower end carrying a roller captured in the track and an upper end pivoted to a sash bracket carried by the window. The link erects to a stand-up position extending between the track and the window when the window is raised. The link collapses to a stored position extending between the lower portion of the track and the sash bracket when the window is lowered. The link has an offset arm carrying a tapered pin which seats in a bushing carried by the door as the window reaches the fully raised position to stabilize the link to the door. The link and the sash bracket have interfitting tongue and groove elements which mate as the window reaches its fully raised position to stabilize the link to the window. A roller yieldably mounted on the window is carried into engagement with an angled wall of the door to force the window against the weather strip defining the window opening.

Window stabilizing mechanism

A seat position control mechanism includes an inboard slave track arrangement having a single track assembly and an outboard control track arrangement having a pair of the same track assemblies arranged in vertically stacked relationship. One of the outboard track assemblies provides for horizontal adjustment of the seat and the other provides for movement of the seat to and from an easy enter position. A control cable arrangement interconnects a tilting seat back and a latch mechanism for the other outboard track assembly to release a latch mechanism and permit movement of the seat to the easy enter position.

Seat position control mechanism

A carrier member mounted on a door window is positioned between the first and second opposed facing spaced apart legs of a door mounted track. The carrier member has an axially extending cylindrical bore communicating between the track legs. First and second bearing balls are mounted within the cylindrical bore and roll against one another and respectively against the first and second track legs to provide low friction precision guided movement of the window between the open and closed positions. Tracks are preferably provided at both the front and rear of the window. One of the tracks extends vertically through the window opening. First and second carrier members and associated rolling balls are mounted on the window in vertically spaced relation and roll along semi-cylindrical grooves extending vertically along the track legs to define the path of rolling movement and support the window against pitching movement and against fore and aft movement relative the door.

Window guidance arrangement

A seat slide bearing assembly includes a bearing unit of low friction plastic material and a roller. The bearing unit includes an apertured body portion which rotatably receives the roller and includes an integral tab fitting within an aperture of the roller to preassemble the bearing unit and roller as a module. Integral legs extend from the body portion and terminate in integral bearing portions having opposed faces, one of which is provided with a series of deflectable ribs.
