Description

Die vorliegende Erfindung betrifft ein teppichintegriertes Fußpolster als passive Rückhaltekomponente in einem Fahrzeug als Einrichtung zur Verminderung der Verletzungsgefahr des Fuß- und Beinbereiches einer auf einem im Inneren eines Fahrzeuges angeordneten Sitz sitzenden Person für den Fall einer unfallbedingten Verformung des Fußraumes nach dem deutschen Patent 196 39 ­ 467.The present invention relates to a carpet-integrated foot cushion as a passive Restraint component in a vehicle as a reduction device the risk of injury to the foot and leg area on one inside a seated person of a vehicle arranged in the event of a accidental deformation of the footwell according to German patent 196 39 467.

Nach dem Hauptpatent wird gemäß zweier Ausführungsformen vorgesehen, im Fußraum einen Gassack eines zugeordneten Airbagmoduls anzuordnen, in den auf ein Auslösesignal hin schlagartig Gas von einem Gasgenerator eingeleitet wird, woraufhin der Gassack den betreffenden Fußraum kurzzeitig in vorgegebenem Maße ausfüllt, um so ein dämpfendes Polster für den Fußbereich zu bilden, bevor die Spritzwand in das Fahrzeuginnere intrudiert.According to the main patent, it is provided according to two embodiments, in Arrange a gas bag of an associated airbag module in the footwell in response to a trigger signal, gas is suddenly introduced by a gas generator , whereupon the gas bag briefly in the footwell concerned fills the specified dimensions to create a cushioning cushion for the Form foot area before the bulkhead intrudes into the vehicle interior.

Bei dem Vorschlag gemäß dem Hauptpatent ist es vonnöten, einen diskreten Gassack im jeweiligen Fußraum anzuordnen und in geeigneter Weise zu befestigen. Dies ist mit einem erhöhten Aufwand und höheren Kosten verbunden.The proposal under the main patent requires a discrete one Arrange the airbag in the respective footwell and in a suitable manner fasten. This is with an increased effort and higher costs connected.

Andererseits besitzen Fahrzeuge neuerer Bauart im Fußraum einen Bodenbelag, der gegenüber früheren Bodenbelägen mindestens um akustikdämpfende Maßnahmen erweitert ist. Insbesondere weisen moderne Bodenbeläge eine akustikdämpfende Schicht auf, die mit der eigentlichen Teppichschicht bedeckt ist.On the other hand, vehicles of a newer design have one in the footwell Flooring that is at least around compared to previous flooring acoustic damping measures is expanded. In particular, modern  Floor coverings on an acoustic damping layer that matches the actual Carpet layer is covered.

Vor diesem Hintergrund ist es die Aufgabe der vorliegenden Erfindung, die Einrichtung gemäß dem Hauptpatent so weiterzubilden, um die Anordnung eines dämpfenden Fußpolsters möglichst kostengünstig bewerkstelligen zu können.Against this background, it is the object of the present invention that Device according to the main patent to further develop the arrangement of a cushioning foot pad as inexpensively as possible can.

Gelöst wird diese Aufgabe durch die Einrichtung gemäß dem Anspruch 1. Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.This object is achieved by the device according to claim 1. Further advantageous embodiments result from the subclaims.

Wie bereits erwähnt, ist Voraussetzung für die erfindungsgemäße Weiterbildung der Einrichtung gemäß dem Hauptpatent, daß der Fußraum mit einem Bodenbelag ausgekleidet ist, der aus einer akustikdämpfenden Schicht und einem daraufliegenden Teppich besteht.As already mentioned, the prerequisite for the invention Training of the facility according to the main patent that the footwell with a floor covering that is lined with an acoustic damping layer and there is a carpet on it.

Erfindungsgemäß ist nun vorgesehen, daß das Fußpolster in dem Fußraum gebildet wird zwischen der akustikdämpfenden Schicht und dem Teppich des Bodenbelages, wobei das Gas vom Gasgenerator in den Raum zwischen die akustikdämpfende Schicht und dem Teppich geleitet wird und der Teppich in dem Bereich des sich ausbildenden Fußpolsters nur bereichsweise an der akustikdämpfenden Schicht fixiert ist.According to the invention it is now provided that the foot cushion in the footwell is formed between the acoustic damping layer and the carpet of the Flooring, the gas from the gas generator into the space between the acoustical damping layer and the carpet is guided and the carpet in the area of the developing foot cushion only in areas on the acoustic damping layer is fixed.

Vorliegend kommt also kein diskreter Gassack mehr zur Anwendung, sondern es wird die Mehrschichtigkeit moderner Bodenbeläge ausgenutzt, um kurzzeitig ein Fußpolster zwischen den Bodenbelagsschichten auszubilden. Die Mehrlagigkeit moderner Bodenbeläge erlaubt es daher, auf die Integration eines konventionellen Gassacks zu verzichten. Die erfindungsgemäße Lösung ermöglicht es sogar unter der Voraussetzung der Modifikation des Produktionsprozesses, das aufblasbare Fußpolster von vornherein mit in den Produktionsprozeß zu integrieren. Somit könnten die Kosten für das Fußpolster extrem niedrig gehalten werden, was zu einer breiten Akzeptanz am Markt führen kann.In the present case, a discrete gas bag is no longer used, but instead the multi-layered nature of modern floor coverings is used for short periods to form a foot cushion between the floor covering layers. The Multi-layered modern flooring therefore allows for integration to dispense with a conventional gas bag. The solution according to the invention enables it even under the condition of modification of the Production process, the inflatable foot pad from the start To integrate the production process. This could reduce the cost of the foot pad  be kept extremely low, leading to widespread market acceptance can lead.

Die das sogenannte Venting ermöglichende Permeabilität des Fußpolsters, die ein Entweichen des Gases aus dem Fußpolster nach dem Aufblasen ermöglicht, ist gegeben durch die Gasdurchlässigkeit der akustikdämpfenden Schicht und des Teppichs, also des gesamten Bodenbelags.The so-called venting permeability of the foot pad, the allows the gas to escape from the foot cushion after inflation, is given by the gas permeability of the acoustic damping layer and the carpet, i.e. the entire floor covering.

Gemäß einer vorteilhaften Weiterbildung ist vorgesehen, daß der Teppich im Bereich des unfallbedingt auszubildenden Fußpolsters nur an vorbestimmten Riß- oder Bruchstellen an der akustikdämpfenden Schicht des Bodenbelages fixiert ist. Bei nichtaktiviertem Gasgenerator sorgt die Fixierung des Teppichs an den besagten Riß- oder Bruchstellen dafür, daß der Teppich keine Falten wirft. Andererseits gestatten diese Riß- oder Bruchstellen nach Aktivierung des Gasgenerators, daß sich das Fußpolster schlagartig innerhalb von wenigen Millisekunden auf volle Größe aufblasen läßt, wobei dann die Fixierung des Teppichs an der akustikdämpfenden Schicht aufgehoben wird, dadurch, daß die Unterseite des Teppichs von den Fixierstellen abreißt. Eine berechenbare Ausbildung des Fußpolsters ist so gewährleistet.According to an advantageous development, it is provided that the carpet in Area of the foot cushion to be trained as a result of an accident only at predetermined ones Cracks or breaks on the acoustic damping layer of the floor covering is fixed. The carpet is held in place when the gas generator is not activated at the said tears or breaks that the carpet does not fold throws. On the other hand, these cracks or fractures allow after activation of the Gas generator that the foot cushion suddenly within a few Inflates to full size in milliseconds, then fixing the Carpet on the acoustic damping layer is lifted, in that the underside of the carpet tears off the fixing points. A predictable Training of the foot pad is guaranteed.

Gemäß einer vorteilhaften Ausführungsform ist es vorgesehen, daß der Gasgenerator, der das Gas in das Fußpolster leitet, ein zweistufiger Gasgenerator ist. An diesen könnten beispielsweise zwei separate Druckleitungen angeschlossen sein, von denen eine Gas in das erfindungsgemäße Fußpolster leitet. Die andere Druckleitung könnte vorteilhafterweise beispielsweise mit einem Frontalairbag in Verbindung stehen. Auf die Auslösung des zweistufigen Gasgenerators würde also sowohl das Fußpolster als auch ein Frontalairbag aufgeblasen werden. Hierdurch wird der erforderliche Materialeinsatz, wie beispielsweise von mehreren Generatoren, auf ein Minimum reduziert. Die zeitliche Abfolge, beispielsweise um wieviel Millisekunden das Fußpolster früher aufgeblasen sein soll als ein Frontalairbag, läßt sich ebenfalls hierdurch steuern.According to an advantageous embodiment, it is provided that the Gas generator that directs the gas into the foot pad, a two-stage Is gas generator. For example, there could be two separate ones Pressure lines must be connected, one of which is gas leads foot pads according to the invention. The other pressure line could advantageously, for example, in connection with a frontal airbag stand. The triggering of the two-stage gas generator would therefore both the foot cushion and a frontal airbag are inflated. This will the required material, such as several Generators, reduced to a minimum. The chronological order, for example  how many milliseconds the foot pad should be inflated earlier than one Frontal airbag, can also be controlled by this.

Alternativ kann vorgesehen sein, daß der Gasgenerator ein einstufiger Gasgenerator ist, an den jedoch mehrere Druckleitungen angeschlossen sind, wobei das Verhältnis ihrer strömungstechnischen Durchmesser das zeitliche Aufblasverhalten des angeschlossenen Gassackes und des Fußpolsters maßgeblich beeinflußt.Alternatively, it can be provided that the gas generator is a one-stage Gas generator, but to which several pressure lines are connected, the ratio of their fluidic diameter the temporal Inflation behavior of the connected gas bag and the foot cushion significantly influenced.

Es ist freilich auch möglich, für das Fußpolster einen separaten Gasgenerator vorzusehen, der getrennt aktiviert werden kann von beispielsweise den Frontalairbags.It is of course also possible to have a separate gas generator for the foot cushion to provide, which can be activated separately from, for example Frontal airbags.

Die Erfindung wird anhand eines Ausführungsbeispiels näher erläutert.The invention is explained in more detail using an exemplary embodiment.

Hierbei zeigt:Here shows:

Fig. 1 den schematischen Aufbau der Einrichtung, Fig. 1 shows the schematic structure of the device,

Fig. 2 die Einrichtung im Ruhezustand, und Fig. 2 shows the device at rest, and

Fig. 3 die Einrichtung direkt nach Zündung des Gasgenerators. Fig. 3 shows the device directly after ignition of the gas generator.

Fig. 1 zeigt deutlich den schematischen Aufbau der Einrichtung. Der Bodenbelag 19 im Fußraum des Fahrzeugs besteht heutzutage aus einer akustikdämmenden Schicht 22, auf die eine Teppichschicht 23 aufgebracht wird. Fig. 1 clearly shows the schematic structure of the device. The floor covering 19 in the footwell of the vehicle nowadays consists of an acoustically insulating layer 22 to which a carpet layer 23 is applied.

Vorliegend sind die schraffierten Bereiche der akustikdämmenden Schicht 22, welche in einer fixierenden Verbindung mit dem Teppich 23 stehen, schraffiert dargestellt. Diejenigen Stellen der Schicht 22, an denen der Teppich 23 nicht fixiert ist, sind hell dargestellt. Man erkennt, daß in den hellen Stellen einige Riß- oder Bruchstellen 21 vorgesehen sind, an denen der Teppich 23 im Ruhezustand des System fixiert ist. Dies gestattet es, daß der Teppich 23 im Ruhezustand des Systems keine Falten wirft.In the present case, the hatched areas of the acoustically insulating layer 22 , which are in a fixing connection with the carpet 23, are shown hatched. Those areas of the layer 22 where the carpet 23 is not fixed are shown in light. It can be seen that in the light spots there are some tears or breaks 21 at which the carpet 23 is fixed when the system is at rest. This allows the carpet 23 not to wrinkle when the system is at rest.

Durch die Schicht 22 hindurch ist eine Gasdruckleitung 25 geführt, welche mit einem Gasgenerator 20 in Verbindung steht.A gas pressure line 25 is guided through the layer 22 and is connected to a gas generator 20 .

Die Funktionsweise wird anhand der Fig. 2 und 3 erläutert.The operation is explained with reference to FIGS. 2 and 3.

Fig. 2 zeigt das System im Ruhezustand, in dem der Bodenbelag 19 zusammengefügt ist aus der akustikdämpfenden Schicht 22 und dem Teppich 23 darauf, vorzugsweise fixiert wie anhand der Fig. 1 erläutert. Der Gasgenerator 20 befindet sich im Ruhezustand. FIG. 2 shows the system in the idle state in which the floor covering 19 is assembled from the acoustically damping layer 22 and the carpet 23 thereon, preferably fixed as explained with reference to FIG. 1. The gas generator 20 is in the idle state.

Kommt es nun zu einem Auslösesignal, wird der Gasgenerator 20 gezündet, wie in Fig. 3 angedeutet. Hierauf wird Gas schlagartig über die Druckleitung 25 in das vorbereitete Fußpolster 24 geleitet, was zu einer Ausbeulung des Teppichs 23 auf der Schicht 22 führt. Gegenüber dem Hauptpatent wird also das Fußpolster erfindungsgemäß nicht durch einen separaten, diskreten Gassack realisiert, sondern vielmehr durch ein Einleiten des Gases vom Gasgenerator 20 zwischen die Schichten 22 und 23 des in der Regel ohnehin vorhandenen Bodenbelages 19 in dem Fahrzeug. Nach dem Aufblasen des Fußpolsters 24 entweicht das Gas durch den gasdurchlässigen Bodenbelag 19, so daß das Fußpolster 24 seine dämpfende Funktion ausüben kann.If a trigger signal now occurs, the gas generator 20 is ignited, as indicated in FIG. 3. Then gas is suddenly passed through the pressure line 25 into the prepared foot pad 24 , which leads to bulging of the carpet 23 on the layer 22 . Compared to the main patent, the foot pad is therefore not realized according to the invention by a separate, discrete gas bag, but rather by introducing the gas from the gas generator 20 between the layers 22 and 23 of the floor covering 19, which is generally present anyway, in the vehicle. After the foot cushion 24 has been inflated, the gas escapes through the gas-permeable floor covering 19 , so that the foot cushion 24 can perform its damping function.

Wie bereits eingangs erwähnt, sind die Auslösezeiten von Airbags bei heutigen Fahrzeugen so früh, daß eine kombinierte Auslösung für das Fußpolster und einen Frontalairbag möglich erscheint.As already mentioned at the beginning, the deployment times of airbags are today's Vehicles so early that a combined trigger for the foot pad and a frontal airbag appears possible.
