An openable roof assembly especially for a sun-, roof of an automotive vehicle has a single hinge mounting the translucent panel along one longitudinal edge to the frame and a single closure element at the opposite longitudinal edge of the panel so that the closure element and the hinge are provided along the surface centerline of the panel. In this way, indifferent zones between hinges are avoided and a uniform distribution of the closing force to the panel can be ensured.

Why it's free to use
- Filed November 17, 1989. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 17, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 17, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
