Description

Sicherheitsvorrichtung für Kraftfahrzeuge Safety device for motor vehicles
Beschreibungdescription
Die Erfindung betrifft eine Sicherheitsvorrichtung für ein Kraftfahrzeug zur Realisierung einer Sicherheitsfunktion, wie sie insbesondere bei einem Unfall erforderlich werden kann. Die Sicherheitsvorrichtung weist mindestens ein Lagerteil mit wenigstens einer Bohrung auf. Ferner ist mindestens ein Bolzen vorhanden, der koaxial in diese Bohrung eingesetzt ist, um das Lagerteil mit einem Anschlussteil zu verbinden. Der Bolzen kann hierbei die Bohrung vollständig durchdringen oder nur abschnittsweise in dieser aufgeommen sein. Die Sicherheitsvorrichtung enthält ferner Mittel zum Entfernen eines Lagerelementes oder des Bolzens, insbesondere eines Pedalbolzens des Kraftfahrzeuges bzw. zum Lösen des Anschlussteils von dem Lagerteil.The invention relates to a safety device for a motor vehicle to implement a safety function, such as may be required in an accident. The safety device has at least one bearing part with at least one bore. Furthermore, there is at least one bolt which is inserted coaxially into this bore in order to connect the bearing part to a connecting part. The bolt can completely penetrate the bore or can only be partially inserted in it. The safety device also contains means for removing a bearing element or the bolt, in particular a pedal bolt of the motor vehicle or for releasing the connecting part from the bearing part.
Derartige Sicherheitsvorrichtungen kommen unter anderem an der Pedalerie im Fußraum von Fahrgastzellen in Kraftfahrzeugen zur Vermeidung von Verletzungsrisiken aufgrund von Auφrallunfällen zum Einsatz. Die Nerletzungsrisiken liegen darin begründet, dass bei einem Auφrallunfall die Insassen nicht in der Lage sind, die auftretenden Beschleunigungskräfte abzufangen, so dass unter anderem die unteren Extremitäten der im Frontbereich sitzenden Person in den Fußraum hinein geschleudert werden. Der gesamte Fußraum kann sich bei der zuvor genannten Unfallsituation extrem verformen. Die in der Folge entstehenden Verletzungen sind für den oder die Betroffenen schmerzhaft und können sogar bis zu lebenslangen Verstümmelungen führen. Um diesem Umstand entgegenzuwirken sind aus dem Stand der Technik unterschiedliche Lösungen bekannt. Hauptsächlich werden zwei Arten von Sicherheitsvorrichtungen unterschieden. Zum einen wird durch Knicken bzw. Wegbiegen eines Anschlussteils - beispielsweise einer Druckstange - vermieden, dass sich das Pedal in Richtung Fahrzeuginnenraum bewegt, zum anderen wird durch Öffnen der Pedallagerstelle, hervorgerufen durch Deformation - beispielsweise Verbiegen - von Strukturteilen, beispielsweise Blechen, ein Eindringen des Pedals in den Fahrzeuginnenraum verhindert.Safety devices of this type are used, inter alia, on the pedals in the footwell of passenger cells in motor vehicles in order to avoid the risk of injury due to impact accidents. The risk of injury is due to the fact that in the event of a crash, the occupants are unable to absorb the acceleration forces that occur, so that, among other things, the lower extremities of the person sitting in the front area are thrown into the footwell. The entire footwell can deform extremely in the aforementioned accident situation. The resulting injuries are painful for those affected and can even lead to lifelong mutilation. In order to counteract this, different solutions are known from the prior art. There are two main types of safety devices. On the one hand prevents the pedal from moving in the direction of the vehicle interior by kinking or bending a connecting part - for example a push rod; on the other hand, opening the pedal bearing point, caused by deformation - for example bending - of structural parts, for example sheet metal, prevents the pedal from penetrating into prevents the vehicle interior.
Aus der Patentschrift DE 100 40 043 ist eine Sicherheitsvorrichtung bekannt, welche durch Öffnen der Pedallagerstelle ein Eindringen des Pedals in den Fußraum verhindert. Die Sicherheitsvorrichtung umfasst einen Lagerbock, in dem die um eine Achse schwenkbaren Pedale auf Bolzen, welche in den Aufnahmen des Lagerbocks festgelegt sind, gelagert sind. Dabei weist der Lagerbock zumindest einen aufweitbaren Abschnitt auf, sodass die bei einem Unfall von außen aufgebrachte Krafteinwirkung zu einer Deformation der vorderen Spritzwand führt und in Folge dessen den Lagerbock aufweitet oder spreizt. Die Aufweitung kann mittels eines keilförmigen Elementes erfolgen, welches zwischen die Schenkel eines Lagerbocks getrieben wird. Die hierzu erforderliche kinetische Energie wird aus der Bewegung der sich bei einem Unfall relativ zueinander verformenden Kraftfahrzeugteile gewonnen. Damit erfolgt die Freigabe der die Fußpedale lagernden Bolzen, so dass die Pedale mit dem Bolzen aus ihrer Halterung gelöst werden und nicht in den Fußraum eindringen.A safety device is known from patent specification DE 100 40 043, which prevents the pedal from entering the footwell by opening the pedal bearing point. The safety device comprises a bearing block in which the pedals which can be pivoted about an axis are mounted on bolts which are fixed in the receptacles of the bearing block. The bearing block has at least one expandable section, so that the external force applied in the event of an accident leads to a deformation of the front bulkhead and as a result expands or spreads the bearing block. The expansion can take place by means of a wedge-shaped element which is driven between the legs of a bearing block. The kinetic energy required for this is obtained from the movement of the motor vehicle parts that deform relative to one another in the event of an accident. This releases the bolts supporting the foot pedals, so that the pedals are released from their holders with the bolts and do not penetrate into the footwell.
Bei der bekannten Sicherheitsvorrichtung tritt der Nachteil auf, dass die Pedallagerstelle nur passiv aufgrund der durch einen Auφrallunfall verursachten Deformation geöffnet wird und damit die Sicherheitsvorrichtung abhängig von Art und Stärke des Unfalls und damit unzuverlässig ist. Zudem sind die bekannten Systeme isoliert von anderen in einem Kraftfahrzeug vorhandenen Sicherheitsvorrichtungen - wie beispielsweise einer Airbagsicherung - und bieten somit keinen umfassenden Schutz.The known safety device has the disadvantage that the pedal bearing point is only opened passively due to the deformation caused by an impact accident, and the safety device is therefore dependent on the type and strength of the accident and is therefore unreliable. In addition, the known systems are isolated from other safety devices present in a motor vehicle - such as an airbag safety device - and therefore do not offer comprehensive protection.
Es ist daher die Aufgabe der vorliegenden Erfindung, eine Sicherheitsvorrichtung zu schaffen, bei der das Öffnen der Lagerstelle, genauer das Entfernen des Lagerbolzens aus der Lagerung, zuverlässiger und unabhängig von Art und Stärke des Unfalls ist und zugleich eine Kopplung mit anderen Sicherheitssystemen gewährleistet wird. Diese Aufgabe wird ausgehend von einer Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 in Verbindung mit dessen kennzeichnenden Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.It is therefore the object of the present invention to provide a safety device in which the opening of the bearing point, more precisely the removal of the bearing pin from the bearing, is more reliable and independent of the type and severity of the accident, and at the same time a coupling with other safety systems is ensured. This object is achieved on the basis of a device according to the preamble of claim 1 in conjunction with its characterizing features. Advantageous developments of the invention are specified in the dependent claims.
Der erfindungsgemäße Gegenstand betrifft eine Sicherheitsvorrichtung zum Entfernen eines Bolzens, insbesondere eines Pedalbolzens in einem Kraftfahrzeug, mit mindestens einem ersten Lagerteil, welches mindestens eine Bohrung für eine Bolzenverbindung zu mindestens einem Anschlussteil aufweist, sowie mindestens einem Bolzen, welcher koaxial in diese Bohrung eingesetzt ist, um das Lagerteil und das Anschlussteil miteinander zu verbinden. Dabei sind Mittel zum Entfernen des Bolzens bzw. ein Lösen des Anschlussteils zur Realisierung einer Sicherheitsfunktion vorgesehen, die als ein Mechanismus ausgebildet sind, der in einem mit dem Lagerteil verbundenen Gehäuse untergebracht und in axialer Verlängerung zu der Bolzenachse mit dem Bolzen verbunden ist. Diese Mittel sind bei einem Unfall aktivierbar.The subject matter of the invention relates to a safety device for removing a bolt, in particular a pedal bolt in a motor vehicle, with at least one first bearing part which has at least one bore for a bolt connection to at least one connection part, and at least one bolt which is inserted coaxially into this bore, to connect the bearing part and the connecting part. Means for removing the bolt or loosening the connecting part for realizing a safety function are provided, which are designed as a mechanism which is accommodated in a housing connected to the bearing part and is connected to the bolt in an axial extension to the bolt axis. These funds can be activated in the event of an accident.
Diese Lösung bietet den Vorteil, dass aufgrund der aktiven wie auch passiven Auslösung der Sicherung die Sicherheitsfunktion der Vorrichtung unabhängig von der Art und Stärke der durch einen Auφrallunfall hervorgerufenen Deformation ist, ohne die bisherigen Möglichkeiten einzuschränken. Weiterhin lässt sich nun die Sicherheitsvorrichtung mit anderen aktiven Sicherheitsvorrichtungen, beispielsweise mit einer Airbagauslösung oder einem Gurtstraffer, koppeln, um so einen kompletteren und umfassenderen Schutz zu bieten. Zudem ist die Auslösung nicht mehr von der Art des Aufprallunfalls abhängig, sondern berücksichtigt vielmehr jegliche Arten von Unfällen, welche eine Sicherheitsfunktion benötigen. Durch die kompakte Bauweise der erfindungsgemäßen Vorrichtung entstehen keine unnötigen Verletzungsrisiken und Einschränkungen durch hervorragende Bauteile.This solution has the advantage that, due to the active as well as the passive triggering of the fuse, the safety function of the device is independent of the type and strength of the deformation caused by an accident, without restricting the previous possibilities. Furthermore, the safety device can now be coupled with other active safety devices, for example with an airbag release or a belt tensioner, in order to offer more complete and comprehensive protection. In addition, the triggering is no longer dependent on the type of impact accident, but rather takes into account any type of accident that requires a safety function. Due to the compact design of the device according to the invention, there are no unnecessary risk of injury and restrictions due to excellent components.
Vorzugsweise kann das Anschlussteil ein in einer Fahrgastzelle eines Kraftfahrzeugs befindliches Fußpedal sein, wobei als Lagerteil ein U-förmiger Lagerbock dienen kann, damit bei einer zweiseitigen Lagerung der Montageaufwand reduzierbar ist. Vorteilhafter Weise ist der Bolzen zweiteilig aufgebaut, damit statt einer großen, einseitig am Bolzen angeordneten Sicherheitsvorrichtung zwei kleinere Sicherheitsvorrichtungen eingebaut werden können, welche beiderseitig des Bolzens platzsparend anzubringen sind und damit ein geringes Verletzungsrisiko in sich bergen.The connecting part can preferably be a foot pedal located in a passenger compartment of a motor vehicle, wherein a U-shaped bearing block can serve as the bearing part, so that the assembly effort can be reduced in the case of two-sided mounting. The bolt is advantageously constructed in two parts, so that instead of a large safety device arranged on one side of the bolt, two smaller safety devices can be installed, which are space-saving to install on both sides of the bolt and thus involve a low risk of injury.
Der Mechanismus der Sicherheitsvorrichtung kann vorteilhafter Weise aus einer Feder- Speichereinheit oder aus einer pyrotechnischen Einheit oder aus einer Kombination dieser Einheiten bestehen. Durch eine aktiv oder passiv lösbare Sicherung kann der Mechanismus sowohl über eine Verformung als auch über eine aktive Ansteuerung sowie eine Kombination aus beiden ausgelöst werden, womit eine deutlich höhere Sicherheitsfunktion realisierbar ist. Zudem ist die Feder-Speicher-Einheit nach Auslösung durch einen einfachen Spannvorgang weiterverwendbar. Zudem stellt die Feder-Speicher-Einheit eine preiswerte Lösung zur Auslösung der Sicherheitsvorrichtung dar.The mechanism of the safety device can advantageously consist of a spring storage unit or a pyrotechnic unit or a combination of these units. The mechanism can be triggered by a deformation or an active control as well as a combination of both by means of an actively or passively releasable fuse, which means that a significantly higher safety function can be implemented. In addition, the spring-memory unit can continue to be used after it has been triggered by a simple tensioning process. In addition, the spring storage unit represents an inexpensive solution for triggering the safety device.
Ein weiterer Vorteil kann darin gesehen werden, den Mechanismus aus einer pyrotechnischen Einheit mit einem Gasgenerator und mit einer aktiv oder passiv lösbaren Sicherung auszuführen, da so ein kostengünstiger, mit wenig Aufwand zu produzierender Mechanismus bereitgestellt wird, welcher sich leicht montieren lässt und sich hervorragend sowohl über eine aktive Sensor- Aktor-Kombination als auch passiv über Deformation auslösen lässt.Another advantage can be seen in executing the mechanism from a pyrotechnic unit with a gas generator and with an actively or passively releasable fuse, since this provides a cost-effective mechanism which can be produced with little effort and which is easy to assemble and can be excellently both can be triggered via an active sensor / actuator combination or passively via deformation.
Eine weitere die Erfindung verbessernde Maßnahme sieht vor, dass bei einem zweiteiligen Bolzen die Mittel zum Entfernen des Bolzens auf je einer Seite des Bolzenendes angebracht sind, da so ein platzsparender, kompakter Mechanismus seitlich der Lagerung angebracht werden kann. Durch die zweiteilige Ausführung ist zudem gewährleistet, dass, sollte ein Mechanismus ausfallen, immer noch der zweite Mechanismus für eine Auslösung der Sicherheitsfunktion sorgt.Another measure improving the invention provides that in the case of a two-part bolt, the means for removing the bolt are attached to one side of the bolt end, since a space-saving, compact mechanism can be attached to the side of the bearing. The two-part design also ensures that should one mechanism fail, the second mechanism will still trigger the safety function.
Von besonderem Vorteil ist, dass die aktiv lösbare Sicherung eine durch eine Sensor- Aktor-Kombination ausgelöste Sicherung ist, da so eine elektrische Kopplung an vorhandene Sicherheitsvorrichtungen wie zum Beispiel an eine Airbagauslösung eines Kraftfahrzeuges möglich ist. Vorzugsweise ist die passiv lösbare Sicherung ein Hebel, welcher einseitig mit dem Lagerbolzen verbunden ist, um bei Verschiebung des Lagerteils die Sicherung auszulösen, da sich so die von der Deformation eines Auφrallunfalls abhängige Auslösung sehr gut über den Hebelarm einstellen lässt.It is particularly advantageous that the actively releasable fuse is a fuse triggered by a sensor / actuator combination, since this enables an electrical coupling to existing safety devices such as, for example, to trigger an airbag in a motor vehicle. The passively releasable fuse is preferably a lever which is connected on one side to the bearing pin in order to trigger the fuse when the bearing part is displaced, since the triggering which is dependent on the deformation of an accident can be adjusted very well via the lever arm.

Ausführungsform.Embodiment.
Die Sicherheitsvorrichtung nach Fig. 1 besteht aus einem als Pedal ausgebildetem Anschlussteil 1 , welches über einen Bolzen 2 mit einem Lagerteil 4 verbunden ist. Das als einteiliger Lagerbock ausgebildete, U-förmige Lagerteil 4 weist in der Darstellung beidseitig unterschiedliche Mechanismen 8 auf. Linksseitig ist ein Mechanismus in Form einer pyrotechnischen Einheit 5 und rechtsseitig ein als Federspeichereinheit ausgebildeter Mechanismus 8 befestigt.1 consists of a connecting part 1 designed as a pedal, which is connected to a bearing part 4 via a bolt 2. The U-shaped bearing part 4, which is designed as a one-piece bearing block, has different mechanisms 8 on both sides in the illustration. A mechanism in the form of a pyrotechnic unit 5 is attached on the left-hand side and a mechanism 8 designed as a spring-loaded unit is attached on the right-hand side.
Der Bolzen 2 besteht aus zwei formschlüssig bzw. kraftschlüssig miteinander verbundenen Bolzenhälften 2a und 2b. In Verbindung mit einem als Federspeichereinheit ausgeführten Mechanismus 8 ist eine Bolzenhälfte 2b mit einem Federteller 3 ausgestattet bzw. verbunden. Der gesamte Mechanismus 8 besteht demnach aus einem Federteller 3, einer Druckfeder 8a und einer Sicherung 7 welche von einem geschlossenen Gehäuse 6 umgeben sind. Vor dem Einstecken der rechten Bolzenhälfte 2b in das Lagerteil 4 wird die Druckfeder 8a über die Bolzenhälfte 2b gesteckt. Beim Einsetzen der Bolzenhälfte 2b in das Lagerteil 4 wird die Druckfeder 8a gespannt. Damit der Bolzen 2 nicht aufgrund der hohen Federkraft der Druckfeder 8a aus dem Lagerteil 4 gezogen wird, wird eine Sicherung 1, die den mit dem Bolzen 2 verbundenen Federteller 3 in der vorgespannten Position arretiert, eingesetzt. Den gesamten Mechanismus 8 umgibt ein geschlossenes Gehäuse 6, welches an den Mechanismus 8 so angepasst ist, dass es die Führung des als Federspeichereinheit ausgebildeten Mechanismus 8 gewährleistet und den Sicherungsmechanismus (nicht dargestellt) aufnehmen kann. Bei aktiver oder passiver Auslösung der Sicherheitsfunktion wird die Sicherung 7 gelöst und die Druckfeder 8a zieht die rechte Hälfte des zweiteiligen Bolzens 2b, welche aufgrund der hohen Federkraft von der linken Bolzenhälfte 2a getrennt wird, aus dem Lagerteil 4 heraus. Die linke Bolzenhälfte 2a wird entweder durch einen analogen, spiegelsymmetrisch zum radialen Querschnitt des Bolzens 2 liegenden Mechanismus 8 oder durch einen in Fig. 2 prinzipiell dargestellten und im folgenden näher beschriebenen Mechanismus entsprechend auf der linken Seite des Lagerteils 4' herausgezogen.The bolt 2 consists of two bolt halves 2a and 2b which are connected to one another in a positive or non-positive manner. In connection with a mechanism 8 designed as a spring storage unit, a pin half 2b is equipped or connected to a spring plate 3. The entire mechanism 8 accordingly consists of a spring plate 3, a compression spring 8a and a fuse 7 which are surrounded by a closed housing 6. Before inserting the right half of the bolt 2b into the bearing part 4, the compression spring 8a is placed over the half of the bolt 2b. When the bolt half 2b is inserted into the bearing part 4, the compression spring 8a is tensioned. So that the bolt 2 is not pulled out of the bearing part 4 due to the high spring force of the compression spring 8a, a fuse 1, which locks the spring plate 3 connected to the bolt 2 in the prestressed position, is used. The entire mechanism 8 is surrounded by a closed one Housing 6, which is adapted to the mechanism 8 so that it ensures the guidance of the mechanism 8 designed as a spring-loaded unit and can accommodate the securing mechanism (not shown). With active or passive triggering of the safety function, the fuse 7 is released and the compression spring 8a pulls the right half of the two-part pin 2b, which is separated from the left pin half 2a due to the high spring force, out of the bearing part 4. The left half of the bolt 2a is pulled out either by an analog mechanism 8 lying mirror-symmetrically to the radial cross section of the bolt 2 or by a mechanism shown in principle in FIG. 2 and described in more detail below on the left side of the bearing part 4 '.
In Fig. 2 ist der in Fig. 1 linksseitig, als eine pyrotechnische Einheit ausgebildete Mechanismus schematisch dargestellt. Hier ist ein Bolzen 2' auf einer Seite mit einem Kolben 9a verbunden und bildet somit ein Kolben-Bolzen- Verbund 9. Den Kolben- Bolzen- Verbund 9 nimmt ein Gehäuse 6' auf, welches unter anderem die Führung des Kolbens 9a gewährleistet und den Anschluss eines Gasgenerators 10 ermöglicht. Bei Auslösen der Sicherheitsfunktion (nicht dargestellt) erzeugt der Gasgenerator 10 in einem kleinen Hohlraum zwischen Kolben 9a und Bolzen 2' innerhalb des Gehäuses 6' einen Überdruck, welcher den Kolben 9a von dem Lagerteil 4' wegbewegt und damit den Bolzen 2' aus dem Lagerteil 4' entfernt. In Fig. 2 the mechanism shown in Fig. 1 on the left, as a pyrotechnic unit is shown schematically. Here, a pin 2 'is connected on one side to a piston 9a and thus forms a piston-pin assembly 9. The piston-pin assembly 9 receives a housing 6' which, among other things, ensures the guidance of the piston 9a and the Connection of a gas generator 10 allows. When the safety function (not shown) is triggered, the gas generator 10 generates a positive pressure in a small cavity between the piston 9a and the pin 2 'within the housing 6', which moves the piston 9a away from the bearing part 4 'and thus the pin 2' from the bearing part 4 'away.
