ABSTRACT:
A sunroof assembly of the lift-up type in which the panel assembly is movable between closed, vent, and opened positions. The cam member coacting with the panel assembly to impart lifting movement to the panel assembly is arranged to undergo angular movement about the longitudinal axis of the track on which the cam member is mounted so that the resultant vertical movement imparted to the panel includes a component corresponding to the vertical rise of the cam member cam surface and a further augmenting component attributable to the angular movement of the cam member. The lifting device employs a U-shaped lever structure with a central hinge portion hinged to an edge of the panel assembly, a relatively short front lever arm portion received in a front shoe slidably and rotationally mounted on an inboard track surface, and a relatively long rear lever arm structure passing through a slot in the cam member and received at its outboard end in a rear shoe slidably and rotationally received on an outboard track surface. As the panel is moved between its closed and vent positions the forward edge of the panel is moved up slightly to break the seal with the roof opening and the panel portion rearwardly of the front edge is moved upward a greater amount to impart to the desired tilt to the panel assembly.
