Description
Bei der Erfindung wird ausgegangen von einem Überrollschutzsystem für ein Kraftfahrzeug, gemäß Oberbegriff des Patentanspruchs 1.at The invention is based on a rollover protection system for a motor vehicle, according to the preamble of the claim 1.
Ein
solches Überrollschutzsystem ist aus der
Die
Aufgabe der Erfindung ist es, ein Überrollschutzsystem der eingangs genannten Art anzugeben, das bei einfacher Bauweise eine hohe Stabilität aufweist.task The invention is a rollover protection system of the above specify the type mentioned, which has a high stability with a simple design.
Gelöst wird diese Aufgabe mit einem Überrollschutzsystem, das die in Anspruch 1 genannten Merkmale aufweist. Weiterbildungen des Überrollschutzsystems sind in den abhängigen Ansprüchen angegeben.Solved This task is accomplished with a rollover protection system having the features mentioned in claim 1. Further developments of the rollover protection system are indicated in the dependent claims.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass durch das erste Gelenk die beiden Bügelschenkel zwar relativ zueinander schwenkbar, jedoch fest miteinander verbunden sind, was bei einem Kraftangriff an diesem Gelenk eine steife, feste Verbindung darstellt. Die beim Fahrzeugüberschlag auftretenden Kräfte in den beiden anderen, unteren Gelenken sind üblicherweise geringer und können darüber hinaus von einem entsprechend ausgelegten Querträger aufgenommen werden. Das erfindungsgemäße Überrollschutzsystem weist also insgesamt eine geringer Bauhöhe in der Ruheposition auf, so dass es speziell in einem zweisitzigen Roadster mit geringem Einbauraum hinter den Fahrzeugsitzen eingesetzt werden kann, jedoch eine genügende Ausfahrhöhe in der Aufstellposition aufweist. Erfindungsgemäß sind also zwei ortsveränderliche Gelenke (erstes und zweites Gelenk) und ein ortsfestes drittes Gelenk vorgesehen.The with the invention mainly achieved advantages to be seen in that by the first joint, the two hanger arms Although pivotable relative to each other, but firmly connected what is a stiff, firm in a force attack on this joint Represents connection. The occurring during the vehicle rollover Forces in the other two lower joints are usually lower and can be moreover of one accordingly designed cross member can be added. The rollover protection system according to the invention So overall has a lower height in the rest position on, making it special in a two-seat roadster with low Installation space behind the vehicle seats can be used, however a sufficient extension height in the installation position having. So according to the invention are two portable Joints (first and second joint) and a fixed third joint intended.
Eine geringe Bauhöhe des Überrollschutzsystems in der Ruheposition wird besonders dann erreicht, wenn die Bügelschenkel jedes Überrollbügels entlang des Querträgers in Reihe zueinander liegen, wie es in Anspruch 2 angegeben ist.A low overall height of the rollover protection system in the Rest position is achieved especially when the hanger arms each roll bar along the cross member in series with each other, as stated in claim 2.
Eine besonders gute Kraftaufnahme wird erzielt, wenn – wie Anspruch 3 beschreibt – das ortsfeste dritte Gelenk tief im Querträger liegt, so dass dieser den Bügelschenkel in einem langen Abschnitt stützen kann, was weiter begünstigt wird, wenn der Querträger ein U-Querschnittsprofil ist, wie Anspruch 4 angibt.A Particularly good power is achieved if - as claim 3 describes - the stationary third joint deep in the cross member lies so that this the hanger arm in a long Section, which further favors is when the cross member is a U-section profile, as claim 4 indicates.
Eine verbesserte Steifigkeit wird mit Bügelschenkeln erzielt, die – gemäß Anspruch 5 – ein geschlossenes Querschnitts-Grundprofil aufweisen.A improved rigidity is achieved with stirrup legs, the - according to claim 5 - a have closed cross-sectional basic profile.
Die Ausfahrhöhe der Überrollbügel kann günstig beeinflusst werden, wenn – Anspruch 6 zufolge – die ortsveränderlichen zweiten Gelenke aneinander vorbei bewegbar sind, wenn die Überrollbügel von der Ruhe- in die Aufstellposition verlagert werden. Nach einer ersten Ausführungsvariante (Anspruch 7) können die zweiten Gelenke in übereinander liegenden Bahnen am Querträger geführt werden. Alternativ (Anspruch 8) können die Bahnen – bezogen auf die Fahrzeuglängsachse – hintereinander liegen. In besonders vorteilhafter ermöglichen diese Ausführungen die Lösung des Zielkonflikts zwischen einer großen Ausfahrhöhe und der vorteilhaften Verwendung von geschlossenen Querschnitts-Grundprofilen (Rohr, Vierkantrohr etc.) für die Bügelschenkel, wenn zusätzlich eine geringer Bauhöhe des Systems in Ruhestellung vorliegen soll. Durch das vorteilhafte Aneinandervorbeibewegen der zweiten Gelenke können die inneren Bügelschenkel in Ruhestellung hintereinander oder übereinander liegen (Anspruch 10). In bevorzugter Ausführung wird zusammen mit den Merkmalen des Anspruchs 2 erreicht, dass sich die beiden Bügelschenkel jedes Überrollbügels über eine wesentliche Fahrzeugbreite erstrecken können, also entlang des Querträgers liegen. In der Aufstellposition können derart lange Bügelschenkel für eine große Ausfahrhöhe sorgen. Zusätzlich oder alternativ kann das erste Gelenk gegenüber dem ersten Bügelende zurückversetzt sein, wie Anspruch 11 angibt, so dass sich die Ausfahrhöhe weiter vergrößern lässt oder kürze innere Bügelschenkel ermöglicht, wodurch ggf. auf das Aneinandervorbeibewegen der zweiten Gelenke verzichtet, gleichzeitig jedoch eine Verstärkung des Querträgers vorgenommen werden kann.The extension height of the roll bar can be favorably influenced if, according to claim 6, the movable second joints are movable past each other when the roll bars are moved from the rest position to the set-up position. According to a first embodiment variant (claim 7), the second joints can be guided in superposed paths on the cross member. Alternatively (claim 8), the tracks - based on the vehicle longitudinal axis - lie behind each other. In particularly advantageous embodiments, these solutions allow the solution of the conflict between a large extension height and the advantageous use of closed cross-section basic profiles (pipe, square tube, etc.) for the bar arms, if in addition a lower height of the system should be in the rest position. Due to the advantageous mutual movement of the second joints, the inner stirrup legs can lie one behind the other or one above the other in the rest position (claim 10). In a preferred embodiment is achieved together with the features of claim 2, that the two stirrup legs of each roll bar can extend over a substantial vehicle width, so lie along the cross member. In the set-up position, such long bar legs can provide a high level of extension. Additionally or alternatively, the first joint may be set back relative to the first strap end, as stated in claim 11, so that the extension height can be further increased or shorter inner bracket legs allows, thereby possibly waiving the Aneinandervorbeibegen the second joints, simultaneously However, a reinforcement of the cross member can be made.
Besonders bevorzugt wird ein Ausführungsbeispiel mit den Merkmalen des Anspruchs 12, wonach die zweiten Gelenke an Kulissensteinen ausgebildet sind, die in geeigneten Führungsbahnen am Querträger geführt sind. Die Führungsbahnen können als Einfach- oder Doppelführung realisiert sein, wie Anspruch 13 beschreibt.Especially preferred is an embodiment with the features of claim 12, after which the second joints on sliding blocks are formed, in suitable guideways on the cross member are guided. The guideways can be realized as a single or double guide, as claim 13 describes.
Ferner wird eine Verrieglungseinrichtung zumindest die vollständige Aufstellposition der beiden Bügelschenkel zueinander fixieren. Die Verriegelungseinrichtung kann jedoch auch zum Verriegeln von Zwischenpositionen dienen.Further a locking device will at least be the complete one Fix the installation position of the two stirrup legs to each other. However, the locking device can also be used to lock Serve intermediate positions.
Ferner ist – wie bei ausfahrbaren bzw. aufstellbaren Überrollschutzsystemen üblich – eine Antriebs- und Auslöseeinrichtung für die Überrollbügel vorgesehen, die mit einer Steuereinrichtung, einem Sensor, Federn (Schrauben- oder Schenkelfedern) und/oder einem Motor und/oder einem pyrotechnischen und/oder magnetischen Elementen ausgestattet ist/sind, um die Überrollbügel in der Ruheposition zu halten, auszulösen und in die Aufstellposition zu bringen.Further is - as usual in extendable or deployable rollover protection systems - one Drive and release device provided for the roll bar, equipped with a control device, a sensor, springs (screw or torsion springs) and / or an engine and / or a pyrotechnic and / or magnetic elements is / are fitted to the roll bars to hold in the rest position, trigger and in the set-up position bring to.
