Abstract
Description
Bei der Erfindung wird ausgegangen von einer Unterfahrschutzeinrichtung gemäß Oberbegriff des Anspruchs 1 sowie von einem Verfahren zum Betreiben einer Unterfahrschutzeinrichtung gemäß Oberbegriff des Anspruchs 6.at The invention is based on an underrun protection device according to the preamble of Claim 1 and a method for operating an underrun protection device according to the generic term of claim 6.
Eine
gattungsbildende Unterfahrschutzeinrichtung und deren Verfahren
zum Betreiben ist der
Es ist Aufgabe der Erfindung, ein Unterfahrschutzeinrichtung bzw. ein entsprechendes Verfahren zum Betreiben einer solchen Einrichtung der eingangs genannten Art zu schaffen, mit der/dem das Fahrverhalten eines Kraftfahrzeugs beeinflussbar ist.It is the object of the invention, an underrun protection device or a corresponding method for operating such a device of the type mentioned at the beginning with which the driving behavior of a motor vehicle can be influenced.
Gelöst wird diese Aufgabe mit einer Unterfahrschutzeinrichtung für ein Kraftfahrzeug, welche die in Anspruch 1 genannten Merkmale umfasst bzw. einem Verfahren zum Betreiben einer derartigen Unterfahrschutzeinrichtung gemäß Anspruch 6. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen angegeben. Insbesondere wird die Unterfahrschutzeinrichtung nach einem der Ansprüche 1 bis 5 gemäß dem Verfahren nach einem der Ansprüche 6 bis 9 betrieben.Is solved this task with an underrun protection device for a motor vehicle, which comprises the features mentioned in claim 1 or a method for operating such underrun protection device according to claim 6. Further features embodying the invention are specified in the subclaims. In particular, the underrun protection device according to one of claims 1 to 5 according to the procedure according to one of the claims 6 to 9 operated.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass das als Unterfahrschutz dienende Flächenelement mit der separaten Druckluftquelle, die den Luftsack druckbeaufschlagt, beliebig oft in die ausgefahrene Betriebsstellung gebracht werden kann, in der es als aerodynamisches Luftleitelement wirkt und beispielsweise die Fahreigenschaften des Kraftfahrzeugs verändert und/oder ggf. den Luftwiderstandsbeiwert des Kraftfahrzeugs optimiert und/oder den Treibstoffverbrauch im Fahrbetrieb senken kann. Außerdem ergibt sich ein sportliches Äußeres des Kraftfahrzeugs, wenn das Flächenelement in Betriebsstellung vorliegt.The with the invention mainly The advantages achieved can be seen in the fact that it serves as underrun protection serving surface element with the separate compressed air source that pressurizes the airbag can often be brought into the extended operating position, in which it acts as an aerodynamic air guiding element and for example the driving characteristics of the motor vehicle are changed and / or the drag coefficient, if applicable of the motor vehicle optimized and / or the fuel consumption in Can lower driving. Moreover results in a sporty appearance of the Motor vehicle if the surface element is in the operating position.
Nach einer Weiterbildung der Erfindung mit den in Anspruch 5 genannten Merkmalen ist vorteilhaft, dass das aus einem elastischen Werkstoff hergestellte Flächenelement beim Ausfahren von der Ruhelage in die Betriebsstellung Rückstellkräfte selbst in sich aufbaut, so dass beim Deaktivieren der Luftquelle bzw. beim Druckentlasten des Luftsackes das Flächenelement selbständig durch die Rückstellkräfte in seine Ruhelage verbracht wird.To a development of the invention with those mentioned in claim 5 It is advantageous that it is made of an elastic material manufactured surface element When extending from the rest position into the operating position, restoring forces themselves builds up in itself so that when the air source is deactivated or when Relieving pressure of the airbag independently through the surface element the restoring forces in his Rest position is spent.
Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen mit Bezug auf die Zeichnung näher erläutert.The The invention is described below with reference to exemplary embodiments closer to the drawing explained.
