Abstract: A convertible top for an automobile includes a rear window of glass or the like connected to the top by a track linkage adapted to guide the rear window between deployed and stored positions as the top is raised and lowered. The convertible top comprises a fold-down frame supporting a fabric top material, and defining a rear panel with a rear window opening therein. The rear window has a lower margin hingedly connected to the rear panel along a lower edge of the rear window opening. The track linkage includes a pair of track members disposed at the laterally opposite side edges of the rear window and slidably coupled to the rear panel to permit pivoting movement of the rear window within a plane which is independent of the rear panel as the convertible top is raised and lowered.
