Abstract
Description
Die vorliegende Erfindung betrifft ein Airbagsystem für Fahrzeuge, insbesondere Motorräder, gemäß dem Oberbegriff des Patentanspruches 1. The present invention relates to an airbag system for vehicles, in particular motorcycles, according to the preamble of claim 1.
Moderne Pkw sind mit einer Vielzahl von Airbagmodulen ausgestattet. Üblicherweise ist dort jedem Airbag ein separater Gasgenerator zugeordnet. Zukünftig wird auch bei Motorrädern der Einsatz von Airbagsystemen erwogen. Insbesondere bei Motorrädern stellt sich jedoch ein Bauraumproblem hinsichtlich der Anordnung von Airbagmodulen. Modern cars are equipped with a variety of airbag modules. A separate gas generator is usually assigned to each airbag there. In the future, the use of airbag systems will also be used on motorcycles considered. However, there is a space problem in particular with motorcycles regarding the arrangement of airbag modules.
Aufgabe der Erfindung ist es, ein Airbagsystem zu schaffen, das insbesondere für den Einsatz bei Motorrädern geeignet ist. The object of the invention is to provide an airbag system that is particularly suitable for use on motorcycles.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen. This object is solved by the features of claim 1. Advantageous refinements and developments of the invention are the See subclaims.
Das Grundprinzip der Erfindung besteht in einem Airbagsystem mit mehreren einzelnen Airbags, denen ein einziger Gasgenerator gemeinsam zugeordnet ist. The basic principle of the invention is an airbag system with several individual airbags to which a single gas generator is assigned is.
Vorzugsweise sind die einzelnen Airbags über eine "Verteilereinrichtung" mit dem zentralen Gasgenerator verbunden. Die Verteilereinrichtung kann beispielsweise ein elektromagnetisch betätigbares Mehrwegeventil sein. Je nach Schaltstellung der Verteilereinrichtung stehen ein bzw. mehrere der daran angeschlossenen Airbags mit dem Gasgenerator in Fluidverbindung. The individual airbags are preferably included via a “distributor device” connected to the central gas generator. The distribution device can for example, an electromagnetically actuated multi-way valve. ever after the switching position of the distributor device, one or more of the connected airbags in fluid communication with the gas generator.
Zum Schalten der Verteilereinrichtung ist ein Stellglied vorgesehen, das beispielsweise elektrisch ansteuerbar ist. Ferner ist eine Steuerelektronik vorgesehen, an die diverse "Fahrzustandssensoren" und/oder "Crashsensoren" angeschlossen sind. Bei diesen Sensoren handelt es sich beispielsweise um Längsbeschleunigungs- bzw. Querbeschleunigungssensoren oder um Nicksensoren, welche die Neigung des Motorrads sensieren. Die Steuerelektronik wertet die Sensordaten aus und steuert bei einem Unfall in Abhängigkeit vom Fahr- bzw. Crashzustand des Motorrads die Verteilereinrichtung so an, dass gezielt ein bzw. mehrere der vorhandenen Airbags aktiviert werden. Es kann vorgesehen sein, dass mehrere Airbags gleichzeitig oder nacheinander durch die Steuerelektronik "angesteuert" werden. An actuator is provided for switching the distributor device is electrically controllable, for example. There is also control electronics provided to which various "driving state sensors" and / or "crash sensors" are connected. These sensors are, for example Longitudinal acceleration or lateral acceleration sensors or around Nick sensors that sense the inclination of the motorcycle. The control electronics evaluates the sensor data and controls in an accident depending on the Driving or crash condition of the motorcycle on the distributor so that One or more of the existing airbags can be specifically activated. It can be provided that several airbags at the same time or in succession can be "controlled" by the control electronics.
Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels im Zusammenhang mit der Zeichnung näher erläutert. Es zeigen: In the following the invention using an exemplary embodiment in Connection with the drawing explained in more detail. Show it:
Fig. 1 und 2 zwei verschiedene Stellungen der Verteilereinrichtung; und Figures 1 and 2 two different positions of the distributor device; and
Fig. 3 eine schematische Darstellung eines Motorrollers mit mehreren Airbags. Fig. 3 is a schematic representation of a scooter with several airbags.
Fig. 1 zeigt ein Mehrwegeventil 1 bestehend aus einem Gehäuse 2, in dem ein Ventilküken 3 drehbar angeordnet ist. Das Mehrwegeventil 1 weist einen Gaseingang 4 und drei Gasausgänge 5-7 auf. Der Gaseingang 4 steht in Fluidverbindung mit einem Gasgenerator 8. An die Gasausgänge 5-7 sind jeweils ein hier nicht dargestellter Airbag eines Fahrzeugs angeschlossen. In der in Fig. 1 gezeigten Schaltstellung des Mehrwegeventils steht der Gasausgang 6 in Fluidverbindung mit dem Gasgenerator 8. Die beiden anderen Gasausgänge, das heißt die Gasausgänge 5, 7 sind in dieser Schaltstellung abgesperrt. Fig. 1 shows a multi-way valve 1 consisting of a housing 2 , in which a valve plug 3 is rotatably arranged. The multi-way valve 1 has a gas inlet 4 and three gas outlets 5-7 . The gas inlet 4 is in fluid communication with a gas generator 8 . An airbag (not shown here) of a vehicle is connected to gas outlets 5-7 . In the switching position of the multi-way valve shown in FIG. 1, the gas outlet 6 is in fluid communication with the gas generator 8 . The other two gas outlets, that is, the gas outlets 5 , 7 are blocked in this switching position.
Das Mehrwegeventil 1 kann beispielsweise ein Magnetventil sein, das durch eine Steuerelektronik (nicht dargestellt) angesteuert wird. An die Steuerelektronik sind verschiedene "Fahrzustandsensoren" angeschlossen, die den Fahr- bzw. Crashzustand überwachen und bei einem Unfall "erkennen", welcher der im Fahrzeug vorhandenen Airbags vordringlich auszulösen ist. In Abhängigkeit davon steuert das Mehrwegeventil zu einem der drei Gasausgänge 5-7 durch bzw. löst bei einem Unfall die an die Gasausgänge 5-7 angeschlossenen Airbags in einer bestimmten Reihenfolge aus. The multi-way valve 1 can be a solenoid valve, for example, which is controlled by control electronics (not shown). Various "driving status sensors" are connected to the control electronics, which monitor the driving or crash status and "recognize" in an accident which of the airbags present in the vehicle is to be triggered as a matter of urgency. Depending on this, the multi-way valve controls to one of the three gas outlets 5-7 or, in the event of an accident, triggers the airbags connected to gas outlets 5-7 in a specific sequence.
Fig. 2 zeigt eine weitere Stellung des Mehrwegeventils 1. Hier steht der Gasgenerator 8 mit dem Gasausgang 7 in Fluidverbindung, wohingegen die anderen beiden Gasausgänge 5, 6 abgesperrt sind. Fig. 2 shows a further position of the multi-way valve 1. Here the gas generator 8 is in fluid communication with the gas outlet 7 , whereas the other two gas outlets 5 , 6 are shut off.
Beispielsweise kann vorgesehen sein, dass bei einem bestimmten aktuellen Fahr- bzw. Crashzustand zunächst der an den Gasausgang 6 angeschlossenen Airbag und anschließend der an den Gasausgang 7 angeschlossene Airbag aktiviert werden. Das heißt, das Mehrwegeventil 1 nimmt in diesem Fall nacheinander die in den Fig. 1, 2 gezeigten Stellungen ein. For example, provision can be made for the airbag connected to gas outlet 6 to be activated first and then the airbag connected to gas outlet 7 for a specific current driving or crash condition. That is, the multi-way valve 1 in this case takes the positions shown in FIGS. 1, 2 one after the other.
Fig. 3 zeigt einen Motorroller 9, der einen überdachte Kabine 10 aufweist, die jedoch seitlich offen ist. Der Motorroller 9 weist mehrere hier nur schematisch angedeutete Airbags 11-15 auf. Der Airbag 11 ist ein seitlicher Kopfairbag. Der Airbag 12 erstreckt sich im wesentlichen parallel zur "A- Säule". Der Airbag 14 dient als Knieairbag und der Airbag 15 als seitlicher Fußairbag. Die Airbags 11-15 können über ein Verteilerventil, ähnlich wie in den Fig. 1, 2 dargestellt, mit einem "zentralen" Gasgenerator verbunden sein. Fig. 3 shows a scooter 9 , which has a covered cabin 10 , but which is open on the side. The scooter 9 has a plurality of airbags 11-15, which are only schematically indicated here. The airbag 11 is a side head airbag. The airbag 12 extends substantially parallel to the "A pillar". The airbag 14 serves as a knee airbag and the airbag 15 as a side foot airbag. The airbags 11-15 can be connected to a "central" gas generator via a distribution valve, similar to that shown in FIGS. 1, 2.
Jedoch brauchen nicht zwingend alle vorhandenen Airbags 11-15 einem Gasgenerator zugeordnet sein. Beispielsweise können die im oberen Fahrzeugbereich angeordneten Airbags 11-13 einem ersten Gasgenerator zugeordnet sein und die im unteren Fahrzeugbereich angeordneten Airbags 14, 15 einem zweiten Gasgenerator. However, all of the existing airbags 11-15 need not be assigned to a gas generator. For example, the airbags 11-13 arranged in the upper vehicle area can be assigned to a first gas generator and the airbags 14 , 15 arranged in the lower vehicle area can be assigned to a second gas generator.
