Description

Vorrichtung zum Entfernen einer Brille vom Kopf einer Person in einem Kraftfahrzeug im Falle des Auslösens eines AirbagsDevice for removing glasses from a person's head in a motor vehicle in the event of an airbag being deployed
Die vorliegende Erfindung betrifft eine Vorrichtung zum Entfernen einer Brille vom Kopf einer die Brille tragenden Person in einem Kraftfahrzeug im Falle eines Unfalls.The present invention relates to a device for removing glasses from the head of a person wearing the glasses in a motor vehicle in the event of an accident.
Bei Unfällen wird eine im Kraftfahrzeug sitzende Person, sofern sie korrekt den Sicherheitsgurt angelegt hat, durch das Auslösen eines Airbags in der Regel vor schweren Körperschäden bewahrt. Dies ist jedoch oft dann nicht der Fall, sofern die Person eine Brille trägt. In diesem Fall verursacht der Airbag oft erhebliche Gesichtsverletzungen, da das Brillengestell von der Kraft des Airbags in das Gesicht der Person gedrückt wird. All zu häufig wird dabei das Nasenbein der Person durch den Nasenbügel der Brille gebrochen. Auch kommt es häufig vor, dass das Gesicht durch die Brillengläser zerschnitten wird. Zur Vermeidung derartiger Verletzungen würde es ausreichen, wenn die Person sich im Falle eines Unfalls die Brille vom Kopf reißen würde. In der Regel verbleibt jedoch oft nicht mehr genügend Zeit. Selbst wenn noch genügend Zeit verbleiben würde, würde die Person meist durch das Unfallgeschehen zu stark in Anspruch genommen und nicht daran denken, sich die Brille vom Kopf zu reißen.In the event of an accident, a person sitting in the motor vehicle, provided that they have fastened their seat belt correctly, is usually prevented from seriously injuring themselves by deploying an airbag. However, this is often not the case if the person wears glasses. In this case, the airbag often causes significant facial injuries because of the force of the glasses frame of the airbag is pressed into the person's face. Too often, the person's nasal bone is broken through the nose piece of the glasses. It is also common for the face to be cut through the glasses. To avoid such injuries, it would be sufficient if the person pulled his glasses off his head in the event of an accident. Usually, however, there is often not enough time left. Even if there were enough time left, the person would usually be overused by the accident and would not think of tearing the glasses off their heads.
Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung bereitzustellen, die sicherstellt, dass im Falle eines Unfalls sich die Brille nicht mehr zwischen dem Airbag und dem Kopf der Person befindet.The object of the present invention is therefore to provide a device which ensures that, in the event of an accident, the glasses are no longer between the airbag and the head of the person.
Diese Aufgabe wird erfindungsgemäß mittels einer Vorrichtung mit den Merkmalen des Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen der Vorrichtung ergeben sich durch die Merkmale der Unteransprüche. Zudem wird eine Brille beansprucht, die mit der erfindungsgemäßen Vorrichtung vorteilhaft zusammenwirkt.This object is achieved according to the invention by means of a device with the features of claim 1. Advantageous configurations of the device result from the features of the subclaims. In addition, glasses are claimed which advantageously cooperate with the device according to the invention.
Die Vorrichtung erhält in einer vorteilhaften Ausführungsform das gleiche Signal wie der Airbag. Hierdurch wird gewährleistet, dass die Person bis zum Auslösen des Airbags, d.h. bis zum Aufprall des Fahrzeugs auf ein Hindernis die Brille vor den Augen behält. Erst wenn auch der Airbag ausgelöst wird, wird die Vorrichtung aktiviert .In an advantageous embodiment, the device receives the same signal as the airbag. This ensures that the person until the airbag deploys, i.e. keep your glasses in front of your eyes until the vehicle hits an obstacle. The device is only activated when the airbag is also triggered.
Damit die Vorrichtung korrekt funktionieren kann, muß die Person die Brille mit dem bzw. den Zugmitteln der Vorrichtung verbinden, sobald sie sich in das Fahrzeug setzt. Die Zugmittel, welche Seile, Ketten oder dünne Gurte sein können, werden von der Vorrichtung wahlweise stets leicht gespannt oder aber hängen schlaff durch. Es ist möglich, die Zugmittel, ähnlich den Sicherheitsgurten, durch einen Spannmechanismus stets unter leichter Zugspannung zu halten. Hierdurch wird gewährleistet, dass ein schnelles Entfernen der Brille vom Kopf der Person im Falle eines Unfalls sichergestellt ist. Die Zugmittel können durch leichtes Ziehen aus der Vorrichtung herausgezogen werden, so dass die Person sich relativ frei im Inneren des Fahrzeugs bewegen kann. Im Falle des Auslösens werden die Zugmittel dann in die Vorrichtung mit hoher Geschwindigkeit gezogen, so dass die Brille auch entgegen leichter Rückhaltekräfte stets sicher vom Kopf der Person gezogen wird.In order for the device to function correctly, the person must wear the glasses with the traction device or devices Connect the device as soon as it sits in the vehicle. The traction means, which can be ropes, chains or thin belts, are either always slightly tensioned by the device or sagging slack. It is possible to keep the traction means, similar to the seat belts, always under a slight tension by means of a tensioning mechanism. This ensures that the glasses are quickly removed from the person's head in the event of an accident. The traction means can be pulled out of the device by light pulling, so that the person can move relatively freely inside the vehicle. In the event of triggering, the traction means are then pulled into the device at high speed, so that the glasses are always safely pulled from the person's head, even against slight restraining forces.
Sofern keine speziell für die Vorrichtung konzipierte Brille verwendet wird, kann die Vorrichtung nur derart im Kraftfahrzeug angeordnet werden, dass die Brille der Person nach oben oder aber vorteilhaft schräg nach oben in Fahrtrichtung vom Kopf gezogen bzw. gerissen wird. Vorteilhaft wird die Vorrichtung dann im Dachhimmel des Kraftfahrzeugs im Bereich der Sonnenblende angeordnet. Die Zugmittel hängen dann vom Dachhimmel herab und können leicht in der Nähe der Brillengläser an den Brillenbügeln befestigt werden. Sofern nur ein Zugmittel verwendet werden soll, muss dieses an dem Brillensteg bzw. Nasenbügel, welcher die Brillengläser miteinander verbindet, von der Person beim Hineinsetzen in das Fahrzeug befestigt werden.Unless glasses specially designed for the device are used, the device can only be arranged in the motor vehicle in such a way that the person's glasses are pulled or torn upwards or advantageously obliquely upwards in the direction of travel. The device is then advantageously arranged in the headlining of the motor vehicle in the area of the sun visor. The traction devices then hang down from the headlining and can easily be attached to the temples near the lenses. If only one traction device is to be used, it must be attached to the eyeglass bridge or nose piece that connects the eyeglass lenses to one another when the person sits in the vehicle.
Es ist weiterhin vorteilhaft möglich, eine extra für die Vorrichtung konzipierte Brille zu verwenden. Diese Brille besitzt eine Sollbruchstelle, eine Rast- oder eine Klemmverbindung, welche im Bereich des Nasenbügels angeordnet ist. Die Zugmittel müssen bei dieser Ausführungsform an den über die Ohren greifenden Bügeln der Brille befestigt werden oder sind an diesen dauerhaft befestigt, sofern die Brille stets im Fahrzeug verbleiben soll. Bei zuletzt genannter Variante muss die Person lediglich ihre normale Brille absetzen und kann sich die am Dachhimmel angeordnete Spezialbrille aufsetzen. In diesem Fall muss die Person keine komplizierten Handgriffe mehr vornehmen, um ihre Spezialbrille mit den Zugmitteln zu verbinden. Gleiches gilt selbstverständlich auch für die Ausführungsform, bei der die Vorrichtung im Dachhimmel angeordnet ist. Es ist selbstverständlich möglich, dass eine Brille mit Sollbruchstelle, Rast- oder Klemmverbindung auch außerhalb des Fahrzeugs getragen werden kann. In diesem Falle muss sie lediglich mit den Zugmitteln verbunden werden.It is also advantageously possible to use glasses specially designed for the device. These glasses has a predetermined breaking point, a snap or a clamp connection, which is arranged in the area of the nose piece. In this embodiment, the traction means have to be fastened to the arms of the glasses, which go over the ears, or are permanently fastened to them, provided that the glasses should always remain in the vehicle. In the latter variant, the person only has to take off their normal glasses and can put on the special glasses arranged on the headlining. In this case, the person no longer has to carry out complicated operations to connect their special glasses to the traction devices. The same naturally also applies to the embodiment in which the device is arranged in the headlining. It is of course possible that glasses with a predetermined breaking point, snap or clamp connection can also be worn outside the vehicle. In this case it only has to be connected to the traction means.
Die von der Vorrichtung an den Zugmittel aufgebrachten Kräfte müssen bei Verwendung der beschriebenen Spezialbrille so groß sein, dass die Sollbruchstelle bzw. die Rast- oder Klemmverbindung sicher getrennt wird und die beiden Brillenhälften sicher vom Kopf der Person wegbefördert werden. Bei Verwendung der Spezialbrille ist die Vorrichtung vorteilhaft in der Kopfstütze angeordnet, da die Brille durch die Zugkräfte der Zugmittel im Nasenbereich in zwei Teile geteilt wird, welche dann von den Zugmitteln seitlich nach hinten am Kopf der Person vorbei weggezogen werden. Hierdurch ergibt sich vorteilhaft, dass die Brillenhälften sofort aus dem Wirkungsbereich des Frontairbags entfernt werden. Bei Verwendung der Spezialbrille kann die Vorrichtung ebenfalls im Dachhimmel angeordnet werden, so dass dann die beiden Brillenhälften nach hinten oben in Richtung Dachhimmel gezogen werden.When using the special glasses described, the forces applied by the device to the traction means must be so great that the predetermined breaking point or the latching or clamping connection is safely separated and the two halves of the glasses are safely transported away from the head of the person. When using the special glasses, the device is advantageously arranged in the headrest, since the glasses are divided into two parts by the tensile forces of the traction means in the nose area, which are then pulled away from the traction means laterally past the person's head. This has the advantage that the halves of the glasses are immediately removed from the effective range of the front airbag. When using the special glasses, the device can also be arranged in the headlining, so that the two halves of the glasses are then pulled upwards towards the headlining.
Die Zugmittel können vorteilhaft mittels Trommel, welche durch eine vorgespannte Feder angetrieben werden, aufgewickelt werden. Es ist jedoch auch vorstellbar, dass die Zugmittel, ähnlich wie die GurtstraffSysteme von Gaspatronen angetrieben werden. Gaspatronen weisen im Gegensatz zu vorgespannten Federn den Vorteil auf, dass ihre Funktion auch über einen langen Zeitraum von z.B. mehreren Jahren noch gewährleistet ist.The traction means can advantageously be wound up by means of drums which are driven by a prestressed spring. However, it is also conceivable that the traction devices, like the belt tensioning systems, are driven by gas cartridges. In contrast to preloaded springs, gas cartridges have the advantage that their function can also be carried out over a long period of e.g. is guaranteed for several years.
Nachfolgend werden anhand von Zeichnungen einige Ausführungsbeispiele der erfindungsgemäßen Vorrichtung näher erläutert.Some exemplary embodiments of the device according to the invention are explained in more detail below with reference to drawings.

Fig. 5: erfindungsgemäße Vorrichtung gemäß der Fig. 4 mit ausgelöstem Airbag. Die Fig. 1 zeigt einen Ausschnitt eines Kraftfahrzeugs 1 im Bereich des Fahrersitzes 5. Das Fahrzeug 1 hat ein Lenkrad 2, in dem ein Airbag 4 angeordnet ist. Das Lenkrad 2 befindet sich unterhalb der Windschutzscheibe 3. Die Person 9 sitzt auf dem Fahrersitz 5, an dessen Rücklehne an der Oberseite eine Kopfstütze 6 befestigt ist. In der Kopfstütze 6 ist die erfindungsgemäße Vorrichtung 7 integriert. Aus der Kopfstütze 6 sind Zugmittel 8 geführt, welche mit der Brille 10 der Person 9 verbindbar sind. Solange der Airbag 4 des Fahrzeugs 1 nicht das Auslösesignal erhält, wird auch die Vorrichtung 7 nicht die Zugmittel 8 mit einer solchen Kraft in die Vorrichtung hineinziehen, dass die Brille 10 vom Kopf der Person 9 gezogen wird. Die Person 9 kann durch Aufbringen relativ kleiner Kräfte die Zugmittel 8 aus der Vorrichtung herausziehen, wodurch sie Ihren Kopf frei bewegen kann. Sobald sich der Kopf der Person 9 wieder der Kopfstütze 6 nähert, werden die Zugmittel mittels eines nicht dargestellten Antriebs der Vorrichtung 7 in die Vorrichtung gezogen, so dass diese nicht beliebig weit aus der Vorrichtung heraushängen und stets die Vorrichtung sofort ansprechen kann.5: Device according to the invention according to FIG. 4 with the airbag triggered. 1 shows a section of a motor vehicle 1 in the area of the driver's seat 5. The vehicle 1 has a steering wheel 2 in which an airbag 4 is arranged. The steering wheel 2 is located below the windshield 3. The person 9 sits on the driver's seat 5, on the back of which a headrest 6 is attached to the top. The device 7 according to the invention is integrated in the headrest 6. Pulling means 8 are guided out of the headrest 6 and can be connected to the glasses 10 of the person 9. As long as the airbag 4 of the vehicle 1 does not receive the trigger signal, the device 7 will not pull the traction means 8 into the device with such a force that the glasses 10 are pulled from the head of the person 9. The person 9 can pull the traction means 8 out of the device by applying relatively small forces, as a result of which they can move their heads freely. As soon as the head of the person 9 again approaches the headrest 6, the traction means are pulled into the device by means of a drive (not shown) of the device 7, so that the device does not hang out as far from the device and can always respond to the device immediately.
Die Fig. 2 zeigt das Auslösen des Airbags 4. Die Vorrichtung 7 erhält ebenso wie der Airbag 4 ein Signal, dass das Kraftfahrzeug 1 deformiert wurde, und dass die Vorrichtung 7 nunmehr auslösen muss. Mittels eines nicht dargestellten Antriebs, welcher zum Beispiel mittels einer Feder oder einer Gaspatrone - ähnlich wie bei einem GurtstraffSystem - realisiert sein kann, wird die Trommel 7a der Vorrichtung angetrieben, so dass das Zugmittel 8 auf dieser Trommel 7a aufgerollt wird. Hierbei werden relativ große Kräfte generiert, die dazu führen, dass die in den Fig. 3a bis 3d erläuterte Spezialbrille durch das Ziehen der Zugmittel 8 an den Bügeln 10b der Brille 10 in zwei Teile zerbricht bzw. getrennt wird. Die beiden Brillenteile werden dann von den jeweiligen Zugmitteln 8 seitlich am Kopf nach hinten in Richtung Kopfstütze 6 gezogen, so dass sie nicht mehr im Bereich zwischen dem Kopf der Person 9 und dem ausgelösten Airbag 4 sind, wenn der Kopf der Person 9 den aufgeblasenen Airbagsack berührt . Sofern das Kraftfahrzeug auch über Seitenairbags verfügt, ist darauf zu achten, dass die seitlich am Kopf der Person entlanggezogenen Teile der Brille nicht zwischen den Kopf und den Seitenairbag geraten. Um dies zu gewährleisten kann das Zugmittel über Umlenkrollen entsprechend geführt sein. Auch ist evtl. eine andere Stelle im Fahrzeug für das Anordnen der erfindungsgemäßen Vorrichtung zu wählen. Es ist ebenso möglich die Vorrichtung pro Sitzplatz des Fahrzeugs doppelt vorzusehen, derart, dass von jeder Vorrichtung jeweils ein Zugmittel und somit ein Brillenteil vom Kopf der Person gezogen wird. Hierdurch ist es leichter möglich, die genaue Bahn jedes Brillenteils im Falle des Auslösens der Airbags und der Vorrichtungen vorzugeben.2 shows the deployment of the airbag 4. The device 7, like the airbag 4, receives a signal that the motor vehicle 1 has been deformed and that the device 7 must now deploy. The drum 7a of the device is driven by means of a drive, not shown, which can be realized, for example, by means of a spring or a gas cartridge, similar to a belt tightening system, so that the traction means 8 is rolled up on this drum 7a. Here are generates relatively large forces, which lead to the fact that the special glasses explained in FIGS. 3a to 3d are broken or separated into two parts by pulling the pulling means 8 on the arms 10b of the glasses 10. The two glasses parts are then pulled laterally by the respective traction means 8 on the head towards the headrest 6, so that they are no longer in the area between the head of the person 9 and the deployed airbag 4 when the head of the person 9 inflates the airbag bag touched . If the motor vehicle also has side airbags, make sure that the parts of the glasses that are pulled along the side of the person's head do not get between the head and the side airbag. To ensure this, the traction device can be guided accordingly via deflection rollers. Another location in the vehicle may also have to be selected for arranging the device according to the invention. It is also possible to provide the device twice per seat of the vehicle, in such a way that each device pulls a traction means and thus a pair of glasses from the head of the person. This makes it easier to specify the precise path of each part of the glasses in the event of the airbags and devices deploying.
Die Fig. 3a zeigt eine Spezialbrille 10 mit zwei Bügeln 10b, zwei Gläsern 10c und dem Nasenbügel lOd, der die Fassung der Brillengläser 10c miteinander verbindet. Die Zugmittel 8 greifen hinten an dem gerundeten Ende jedes Bügels 10b an. Sobald, wie in Fig. 3b dargestellt, Kräfte F an den Zugmittel 8 wirken, wird die Spezialbrille 10 in zwei Teile zerlegt. Dies geschieht dadurch, dass die Brille 10 aufgrund der Reaktionskraft R, welche durch das Nasenbein der Person aufgebracht wird, nicht in Richtung der Kräfte F bewegt werden kann. Hierdurch entstehen resultierende Kräfte Fr, welche die beiden Brillengläser 10c auseinandertreiben und die in dem Nasenbügel lOd vorhandene Sollbruchstelle oder Klemm- oder Schnappverbindung lösen bzw. aufbrechen. Die beiden einzelnen Brillenteile können dann von den Zugmitteln 8 weiter an der Seite des Kopfes nach hinten gezogen werden .3a shows special glasses 10 with two temples 10b, two glasses 10c and the nose strap 10d, which connects the frame of the spectacle lenses 10c to one another. The traction means 8 engage at the rear of the rounded end of each bracket 10b. As soon as, as shown in Fig. 3b, forces F act on the traction means 8, the special glasses 10 are broken down into two parts. This happens because the glasses 10 cannot be moved in the direction of the forces F due to the reaction force R, which is applied by the person's nasal bone. This creates resulting forces F r , which drive the two spectacle lenses 10c apart and loosen or break open the predetermined breaking point or clamping or snap connection present in the nose clip 10d. The two individual glasses parts can then be pulled further back by the traction means 8 on the side of the head.
Die Fig. 3c zeigt eine Frontansicht von der Spezialbrille 10 im nicht zerlegten Zustand.3c shows a front view of the special glasses 10 in the non-disassembled state.
Die Fig. 3d zeigt, wie durch die resultierende Kraft Fr die beiden Brillenhälften zerlegt werden. Die Schnappverbindung besteht aus einem Teil 10d in das ein Teil 10dΛΛ der anderen Brillenhälfte eingreift und verrastet. Durch die resultierende Kraft Fr wird diese Verrastung gelöst.FIG. 3d shows how the two halves of the glasses are broken down by the resulting force F r . The snap connection consists of a part 10d in which a part 10d ΛΛ of the other half of the glasses engages and latches. This locking is released by the resulting force F r .
Die Fig. 4 und 5 zeigen eine alternative Ausführungsform, bei der die erfindungsgemäße Vorrichtung 17 im Bereich der Sonnenblende des Fahrzeugs angeordnet ist. Die Vorrichtung 17 weist einen nicht dargestellten Antrieb auf, der die Trommel 17a bei Bedarf antreiben kann. Das Zugmittel 8 ist in diesem Fall mit dem Nasenbügel oder aber den seitlichen über die Ohren der Person geführten Bügel der Brille 10 verbunden. Beim Auslösen des Airbags 4, wie es in Fig. 5 dargestellt ist, wird die Brille durch die Vorrichtung 17a nach vorn oben vom Kopf der Person 9 gezogen, so dass die Brille 10 nicht mehr zwischen dem ausgelösten Airbagsack 4 und dem Kopf der Person ist, sobald dieser in den Airbagsack fällt.4 and 5 show an alternative embodiment in which the device 17 according to the invention is arranged in the region of the sun visor of the vehicle. The device 17 has a drive, not shown, which can drive the drum 17a if necessary. In this case, the traction means 8 is connected to the nose piece or to the side pieces of the glasses 10 which are guided over the person's ears. When the airbag 4 is triggered, as shown in FIG. 5, the glasses are pulled forward upward from the head of the person 9 by the device 17a, so that the glasses 10 are no longer between the triggered airbag bag 4 and the head of the person as soon as it falls into the airbag bag.
Es ist selbstverständlich möglich, die erfindungsgemäße Vorrichtung auch an anderen Stellen im Kraftfahrzeug anzuordnen, wobei dann eventuell andere Spezialbrillen erforderlich sind, die jedoch auch entsprechend des in den Figuren 3a bis 3d gezeigten Prinzips funktionieren können. Insbesondere kann die erfindungsgemäße Vorrichtung auch unterhalb einer Kopfstütze im Sitz des Fahrzeugs angeordnet werden, wobei dann evtl. die Zugmittel über Umlenkmechanismen in oder an der Kopfstütze umgelenkt werden müssen. It is of course possible to use the device according to the invention at other points in the motor vehicle to be arranged, in which case other special glasses may be required, which, however, can also function in accordance with the principle shown in FIGS. 3a to 3d. In particular, the device according to the invention can also be arranged below a headrest in the seat of the vehicle, in which case the traction means may have to be deflected in or on the headrest via deflection mechanisms.
