Abstract
Windschott (1) für ein Cabriolet, mit einem zwischen einer Ablagestellung und einer Wirkstellung verlagerbaren Windschottbügel (3), an dem ein flexibles Flächengebilde (14) mit einem ersten Ende (16) befestigt ist, das mit Abstand zum Windschottbügel (3) mit einem zweiten Ende (17) an einer in einer Rollachse (20) drehbar gelagerten Wickelwelle (19) befestigt ist, auf der es in der Ablagestellung des Windschottbügels (3) aufgewickelt und von der es in Wirkstellung des Windschottbügels (3) abgewickelt ist, dadurch gekennzeichnet, dass die Rollachse (20) der Wickelrolle (19) linear verschiebbar in Richtung der Fahrzeuglängsachse FL gegen die Kraft einer Federeinrichtung (24) gelagert ist. Wind deflector (1) for a convertible, with a wind deflector bracket (3) which can be displaced between a storage position and an active position and to which a flexible sheet-like structure (14) is attached with a first end (16) which is spaced from the wind deflector bracket (3) with a second end (17) is attached to a winding shaft (19) rotatably mounted in a roll axis (20), on which it is wound in the storage position of the wind deflector bracket (3) and from which it is unwound in the active position of the wind deflector bracket (3), characterized in that that the roll axis (20) of the winding roll (19) is mounted linearly displaceable in the direction of the vehicle longitudinal axis FL against the force of a spring device (24).
Description
Bei der Erfindung wird ausgegangen von einem Windschott für ein Cabriolet, gemäß Oberbegriff des Patentanspruchs 1.The invention is based on a wind deflector for a convertible according to the preamble of claim 1.
Ein solches Windschott ist aus der
Es ist Aufgabe der Erfindung, ein Windschott der eingangs genannten Art vor Beschädigungen zu schützen.It is the object of the invention to protect a wind deflector of the type mentioned at the beginning from damage.
Diese Aufgabe wird gelöst mit einem Windschott, welches die in Anspruch 1 genannten Merkmale aufweist. Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved with a wind deflector which has the features mentioned in claim 1. Further developments of the invention are the subject of the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass durch die linear verschiebbare Lagerung der Wickelwelle gegen die Kraft einer Feder bei einer auf das Flächengebilde in Wirkstellung einwirkenden, Kraft, beispielsweise Windkraft während der Fahrt des Kraftfahrzeugs, eine gewisse Nachgiebigkeit erreicht wird, die Beschädigungen an dem Flächengebilde, insbesondere der Rollobahn, vermeiden soll. Wirkt die Kraft auf das Flächengebilde ein, kann die Wickelwelle entgegen der Kraft der Federeinrichtung etwas verlagert werden, wodurch die Spannung aus dem Flächengebilde herausgenommen wird. Vorteilhaft ist die Erfindung jedoch auch bei einer mechanischen Belastung des Flächengebildes, beispielsweise wenn ein Fahrzeugsitz bei einer Verstellbewegung gegen das aufgespannte Flächengebilde fährt. Die dadurch eingebrachte Spannung in das Flächengebilde kann zumindest reduziert werden, wenn die Wickelwelle durch ihre erfindungsgemäße Lagerung nachgibt.The advantages mainly achieved with the invention are to be seen in the fact that the linearly displaceable mounting of the winding shaft against the force of a spring in the case of a force acting on the fabric in the operative position, for example wind force while the motor vehicle is in motion, achieves a certain flexibility, which is intended to avoid damage to the flat structure, in particular the roller blind. If the force acts on the sheet-like structure, the winding shaft can be displaced somewhat against the force of the spring device, as a result of which the tension is removed from the sheet-like structure. However, the invention is also advantageous in the event of a mechanical load on the sheet-like structure, for example when a vehicle seat moves against the stretched sheet-like structure during an adjustment movement. The tension thus introduced into the flat structure can at least be reduced if the winding shaft yields due to its mounting according to the invention.
Bei einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Federeinrichtung ein Federelement umfasst, dessen Federkraft entgegen der Abrollrichtung des Flächengebildes wirkt. Alternativ wäre es möglich, zwei Federelemente für die Federeinrichtung vorzusehen, von denen jedes in Richtung der Fahrzeuglängsachse eine Kraft ausübt, wobei die Kräfte der Federelemente gegensätzlich orientiert sind. Damit wird die Wickelwelle bei einem Kräftegleichgewicht der Federelemente mittig gehalten.In an advantageous embodiment of the invention, it is provided that the spring device comprises a spring element, the spring force of which acts against the rolling direction of the sheet-like structure. Alternatively, it would be possible to provide two spring elements for the spring device, each of which exerts a force in the direction of the longitudinal axis of the vehicle, the forces of the spring elements being oriented in opposite directions. The winding shaft is thus held in the middle when the forces of the spring elements are in equilibrium.
Bevorzugt wird weiterhin eine Ausführungsform, die sich durch die Einfachheit der Lösung auszeichnet. Danach ist die Wickelwelle an einem seitlichen Lagerbock in ihrer Rollachse gelagert und der Lagerbock linear verschiebbar gegen die Kraft der Federeinrichtung geführt. Selbstverständlich wird eine solche Federeinrichtung für beide Enden der Rollachse vorgesehen. Entsprechendes gilt dann, wenn ein Lagerbock vorgesehen sein soll.Furthermore, an embodiment is preferred which is distinguished by the simplicity of the solution. Thereafter, the winding shaft is mounted on a lateral bearing block in its roll axis and the bearing block is linearly displaceable against the force of the spring device. Of course, such a spring device is provided for both ends of the roll axis. The same applies if a bearing block is to be provided.
