ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a vehicle having a sliding roof with a spoiler as is disclosed in DE-B-1 008 592.
2. Discussion of the Prior Art
When the concept of using a simple spoiler, which is successful in a certain type of vehicle, is transferred to other types of vehicle, it has emerged that the draft and noise phenomena cannot always be satisfactorily reduced with it. The success is dependent to a greater or lesser extent on the particular shape of the body and on other factors. Spoilers which are disclosed in DE-B-1 008 492, which forms the generic type, have a passage opening and show an improvement to this problem.
The aim of all spoilers of this type is to reduce the noises which are also known as drumming and which may occur when the fabric sliding roof is partially or completely open.
SUMMARY OF THE INVENTION
The invention is based on the object of improving a vehicle of the generic type in respect of achieving this object using simple means. Pursuant to this object, and others which will become apparent hereafter, one aspect of the present invention resides in a vehicle comprised of a fixed roof with an opening therein, a fabric sliding roof arranged at the opening in the fixed roof so as to be slidable between an open position and a closed position, and a spoiler arranged on the fixed roof in a region of a front edge of the sliding roof so as to extend transversely over the vehicle for the purpose of reducing draft and noise phenomena in the interior of the vehicle when the sliding roof is open. The spoiler has at least one passage opening configured to receive some of the air streams striking against the spoiler during movement of the vehicle in a direction of travel. A deflecting device is arranged in a rearward region of the spoiler relative to the direction of travel. The deflecting device affects the air flow near the spoiler and is designed as an essentially upward extending part.
In another embodiment of the invention the deflecting device is integrally formed on an upper edge of the spoiler.
In still a further embodiment of the deflecting device is arranged on the fixed roof between the passage opening in the spoiler and the front edge of the sliding roof.
In still another embodiment the upwardly extending part is formed integrally on the upper edge of the spoiler as a projection in the form of a bead.
Yet a further embodiment of the invention provides that the deflecting device arranged between the passage opening and the front edge of the sliding roof is designed as a web which forms a component of the spoiler.
In still yet another embodiment of the invention, the upper edge of the web is integrally formed on the upper edge of the spoiler so as to lie in the continuation of the contour of that section of the spoiler which is situated in front of it.
