Abstract
A roof hatch, particularly to a roof hatch intended for vehicle roofs. The roof hatch has a cover, which, for exposing a roof opening defined by a frame in a fixed roof surface, 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 which is centrally supported on the inner side of the cover, and are additionally guided in guideways fixed to the cover, which essentially have circular shape.
