Abstract: The invention relates to a device for actuating a cover (2) for selectively closing an opening (66) in a surface (3) which surrounds the latter in a first position or for at least partially clearing the opening in a second position, the cover (2) being formed especially by the top in the opening in the roof of a motor vehicle which forms the surface (3), and the device comprising the following means: a swivelling arm which extends from the front end to the back end and which is provided with means for attachment of the cover (2); a lifting device (14) to produce a swivelling motion on the swivelling arm relative to the surface (3), and drive to apply force to the lifting device (14) and to move the cover (2) between the first and the second position in that the swivelling arm has at least two elements (A, C) which are connected to one another to be able to move or telescope, the end (30) of one of the elements (A) being hinged via a fulcrum to the stationary part of the device or the surface (3).

Abstract: A fabric roof assembly is disclosed which can be electrically operated comprises a plurality of transverse cross-members adapted to slide in guide rails which extend along each side of an opening of the roof. The assembly includes a front member which supports a front end of the fabric panel, movement of the front member within the opening causing the fabric panel to move from an open position to a position covering the opening. A tensioning and closing mechanism is carried by the front member to tension and close the roof, and driving members are provided which slide along the guides rails and to operate with the front member through the tensioning and closing mechanism. The driving member is the only part which needs to work in the guide rails, with the tensioning and closing mechanism supported by the front member. This allows the walls of the guide rails to be kept to a minimum.
