ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a method for opening and closing an open roof construction of a vehicle having a roof opening in its fixed roof; and also to such an open roof construction for use therewith.
Such a method and such an open roof construction are for example known from DE-C-19542884.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a new way of opening and closing a roof. In particular, a multiple spoiler roof is provided, as it were, wherein a single panel is divided up into several louvres. The forces which are exerted on these smaller louvres when the vehicle is driving are considerably smaller than in the case of a large panel. This makes it possible to choose a larger roof opening. Due to the smaller forces, the louvres can furthermore be supported far to the front of each louvre, as a result of which the louvres can be moved close together. This in turn makes it possible to release a larger part of the roof opening in the entirely open position of the open roof construction, without this necessarily leading to instability in the support of the louvres.
