Abstract: A single rail window regulator that uses a plate with two spaced, parallel guides that are integral to the plate. A lift member, adapted to receive a window pane, is slidably coupled to both guides. A cable is wrapped around two opposing pulleys that are mounted on the plate and a cable drum that is coupled a drive system. The ends of the cable are attached to the lift member. Activating the drive system moves the lift member along the rails.

Abstract: A sunroof assembly has a frame, including two tracks, that mount to a vehicle roof. An arm is slidably mounted in each track, with each arm including attachment points for mounting a panel or a bracket holding a panel thereto. A trolley is slidably mounted in each track and engages the arm. Each trolley has a threaded bore in meshing engagement with a power screw rotatably mounted in the track. A single motor is coupled via a transmission to two flexible drive cables, each of which is connected to one of the power screws. This basic structure minimizes the component count of the sunroof, and hence its manufacturing costs.
