CA 2161786

The invention relates to a roof hatch, particularly to a roof hatch intended for vehicle roofs. Such a roof hatch has a cover, which, for exposing a roof opening, defined by a frame, is alternately, or also, simultaneously, tiltable at two opposite sides. In order to facilitate a low-friction and low-loss actuation with minor force, the push rods actuating the extension devices, in accordance with the invention, are pivotally supported with one end, and with their other ends are guided in cam surfaces of a driven cam disk, centrally supported at the inner cover side, and on the other hand, are additionally guided at cover-fixed guideways, which essentially have circular shape (Fig. 1).

L'invention concerne une tabatière (2), notamment pour pavillon de véhicule. Les tabatières de ce type comportent un capot (5) pouvant être soulevé tour à tour ou conjointement sur deux côtés opposés pour dégager une ouverture (3) ménagée dans le pavillon et délimitée par un cadre. Afin que ce système puisse être manoeuvré avec le moins de frottement et le moins de pertes possible en nécessitant peu de force, il est prévu qu'une des extrémités des tiges de commande (14) qui actionnent les dispositifs d'ouverture soient montée rotative sur les dispositifs d'ouverture et que leur autre extrémité soit guidée d'une part dans des glissières à coulisse (18, 19) d'un disque de commande piloté, situé au centre de la face intérieure du capot, et d'autre part sur des glissières de guidage (23, 24) sensiblement en arc de cercle, fixées au capot.
