Abstract: A controller is provided for vehicle sunroofs and the like, of the type having a retractable closure. The controller comprises two tracks mounted on opposite sides of a main frame. Guides project laterally outwardly from the sides of the closure, and are received in mating channels in the tracks to slidingly support the closure for fore-to-aft translation between fully open and fully closed positions. A seal is positioned between the closure and the frame to form a weathertight seal therebetween. A pair of cam mechanisms are positioned in mating grooves in the tracks, and are shaped so that rotation of the cam mechanisms raises the closure into a fully closed and locked position. The controller also includes a first lock to releasably retain the closure in one of a plurality of different partially open positions, and a second lock to releasably retain the closure in the fully open position.

Abstract: A controller is provided for vehicle sunroofs and the like, of the type having a retractable door or closure. The controller comprises two tracks mounted in a main frame portion of the sunroof, along opposite sides of the closure. Guides project laterally outward from the sides of the closure, and are matingly received in the tracks to slidingly support the closure for fore-to-aft translation between open and closed positions. A seal is located between the closure and the frame to form a weathertight seal therebetween. The guides include cams or eccentrics that are positioned in the tracks, and are shaped so that rotation of the eccentrics raises and lowers the closure in the main frame. When the eccentrics are rotated to a locked position, the closure is raised into abutting, compressive contact with the seal to sealingly close the opening. When the eccentrics are rotated into an unlocked position, the closure is lowered out of abutting contact with the seal to permit the closure to be freely opened.
