Abstract
Abstract A sliding and lifting roof for vehicles having a cover that is guided in lateral guide rails and that can selectively be either lowered at its rear side out of an opening in the roof and then slid back under a fixed part of the roof, or tilted out so that its rear side is lifted above the fixed part of the roof. The cover, close to its rear edge, at each side, has a hold-down device which, when the cover is tilted out, passes through an opening in the corresponding guide rail, and when the cover is being closed, engages against an upstanding guide surface in the area of the rear edge of the opening, and which, when the rear side of the cover is being lowered and pushed back under the fixed part of the roof, dips into the guide rail and is secured by said guide rail against upward adjusting movements. The ability to prevent rearward shifting of the cover is improved by providing, close to a front edge of the cover, on each side, an additional hold-down device which, when the rear edge of the cover is lowered below the fixed part of the roof, can be slid along the guide rail and which, when the cover is tilted out, contacts a rear-side guide connected with the guide rail, said rear-side guide remaining engaged with the additional hold-down device throughout the continued range of movement of the cover to a fully tilted out position.
