Description

Airbagmodul für ein Kraftfahrzeug  Airbag module for a motor vehicle
Beschreibung description
Die Erfindung betrifft ein Airbagmodul für ein Kraftfahrzeug gemäß dem Oberbegriff des Anspruchs 1 . Ein solches Airbagmodul weist einen Gassack auf, der zum Schutz einer Person aufblasbar ist, ein mit dem Gassack zusammenwirkendes Band, das insbesondere flexibel ausgebildet ist und längs erstreckt ausgebildet sein kann, einen Träger des Airbagmoduls zum Tragen von Komponenten des Airbagmoduls sowie ein Halteelement, über das das besagte Band am Träger festgelegt ist. The invention relates to an airbag module for a motor vehicle according to the preamble of claim 1. Such an airbag module has an airbag which is inflatable to protect a person, a cooperating with the gas bag band, which is particularly flexible and can be formed to extend longitudinally, a carrier of the airbag module for supporting components of the airbag module and a holding element via that the said band is fixed to the carrier.
Der Erfindung liegt das Problem zugrunde, ein Airbagmodul der eingangs genannten Art zu schaffen, dass möglichst kostengünstig und einfach herzustellen ist. The invention is based on the problem to provide an airbag module of the type mentioned that is as inexpensive and easy to manufacture.
Dieses Problem wird durch ein Airbagmodul mit den Merkmalen des Anspruchs 1 gelöst. This problem is solved by an airbag module having the features of claim 1.
Danach ist vorgesehen, dass das Halteelement einstückig an den Träger angeformt ist. Hierbei kann der Träger samt daran angeformten Halteelement beispielsweise aus einem Kunststoff (z.B. Spritzgussverfahren) oder Metall gegossen oder in einer sonstigen Weise ausgeformt sein. Weiterhin ist vorgesehen, dass das Halteelement derart an den Träger angeformt ist, dass das Halteelement beim Einwirken einer vordefinierbaren Kraft auf das Halteelement vom Träger abgetrennt wird und das Band freigibt, d.h., das Band ist nun nicht mehr am Träger festgelegt. Thereafter, it is provided that the holding element is integrally formed on the carrier. In this case, the support together with the retaining element integrally formed thereon can be cast, for example, from a plastic (for example injection molding method) or metal or shaped in some other way. Furthermore, it is provided that the holding element is formed on the carrier in such a way that the holding element is separated on exposure to a predefinable force on the holding element from the carrier and the band releases, that is, the band is no longer fixed to the carrier.
Bevorzugt ist das Halteelement dabei über eine Sollbruchverbindung (auch Sollbruchstelle genannt) mit dem Träger verbunden, die z.B. durch eine umlaufende Schwächungslinie gebildet sein kann. Eine solche Schwächungslinie wird beispielsweise gebildet, indem im Bereich jener Linie bzw. am Übergang zwischen Halteelement und eigentlichem Träger (abschnittsweise) weniger Material des Trägers bzw. Halteelementes vorhanden ist als in der Umgebung der besagten Linie, so dass das Halteelement bei Einwirken der besagten Kraft entlang dieser Sollbruchstelle (Schwächungslinie) vom Träger definiert abgetrennt wird. Preferably, the holding element is connected via a predetermined breaking connection (also called breaking point) to the carrier, which may be formed for example by a circumferential line of weakness. Such a weakening line is formed, for example, in the region of that line or at the transition between the holding element and actual carrier (sections) less material of the carrier or holding element is present than in the vicinity of said line, so that the Holding element is defined when the action of said force along this predetermined breaking point (line of weakness) is separated from the carrier.
Vorzugsweise steht das Halteelement des Weiteren vom Träger ab, und zwar insbesondere entlang einer Erstreckungsrichtung des Halteelementes, die insbesondere entgegen einer Hauptentfaltungsrichtung verläuft, entlang der der Gassack sich zum Schutz einer Person beim Aufblasen entfaltet. Das Halteelement ist also insbesondere als eine Erhebung bzw. Vertiefung des Trägers ausgebildet. In diesem Sinne weist das Halteelement also bevorzugt eine umlaufende Wandung auf, über die es an den Träger angeformt ist sowie des Weiteren einen Boden, von dem jene Wandung abgeht. Hierbei ist insbesondere die besagte Sollbruchstelle am Fuße jener Wandung vorgesehen, also am Übergang zwischen Träger und Wandung und umläuft bevorzugt entsprechend. Preferably, the holding element further protrudes from the carrier, in particular along an extension direction of the holding element, which in particular runs counter to a main deployment direction along which the airbag deploys to protect a person during inflation. The holding element is thus designed in particular as a collection or depression of the carrier. In this sense, therefore, the holding element preferably has a circumferential wall, via which it is integrally formed on the carrier and, moreover, a bottom from which that wall leaves. Here, in particular, the said predetermined breaking point is provided at the foot of that wall, ie at the transition between the carrier and the wall and preferably rotates accordingly.
Bevorzugt ist vorgesehen, dass das Band zum Festlegen am Träger um das Halteelement, insbesondere um dessen Wandung, herumgelegt ist, also das Halteelement bzw. dessen Wandung z.B. umläuft. Hierzu kann das Band beispielsweise ein Schlaufe aufweisen, die die Wandung des Halteelementes umläuft. Für den Fall, dass das Halteelement vom Träger abgetrennt wird, ist das Band folglich frei und nicht länger am Träger festgelegt. It is preferably provided that the strap is placed around the retaining element, in particular around its wall, for fastening to the carrier, that is to say the retaining element or its wall, for example. circulates. For this purpose, the band may for example have a loop which surrounds the wall of the holding element. In the event that the holding element is separated from the carrier, the band is thus free and no longer fixed to the carrier.
Zum Abtrennen des Halteelementes vom Träger ist vorzugsweise eine Bewegungserzeugungsvorrichtung vorgesehen, insbesondere in Form eines Gasgenerators, die dazu eingerichtet und vorgesehen ist, das Halteelement vom Träger abzusprengen, d.h., insbesondere die Sollbruchstelle zum Abtrennen des Halteelementes zu zerstören. For separating the holding element from the carrier, a movement generating device is preferably provided, in particular in the form of a gas generator, which is designed and intended to blast off the holding element from the carrier, that is, in particular to destroy the predetermined breaking point for separating the holding element.
Hierzu weist das Halteelement vorzugsweise eine Durchgangsöffnung auf, die bevorzugt im Boden des Halteelementes vorgesehen ist, in die die Bewegungserzeugungsvorrichtung eingeführt ist, so dass die besagte Wandung des Halteelementes jene Bewegungserzeugungsvorrichtung im Querschnitt umläuft. For this purpose, the holding element preferably has a passage opening, which is preferably provided in the bottom of the holding element, in which the movement generating device is inserted, so that said wall of the holding element that movement generating device rotates in cross section.
Hierdurch kann die Bewegungserzeugungsvorrichtung nach einem Aktivieren eine Kraft auf das Halteelement ausüben derart, dass das Halteelement entlang der besagten Sollbruchstelle vom Träger abgetrennt wird, und zwar insbesondere samt Bewegungserzeugungsvorrichtung. Zum Festlegen der Bewegungserzeugungsvorrichtung in jener Durchgangsöffnung des Halteelementes dient insbesondere ein Klemmelement, das derart am Träger befestigbar ist, dass es einen Anlagebereich der Bewegungserzeugungsvorrichtung gegen das Halteelement drückt und dabei insbesondere die Durchgangsöffnung überdeckt bzw. verschließt. Dabei wird jener Anlagebereich insbesondere gegen einen die Durchgangsöffnung berandenden Randbereich des Bodens des Halteelementes gedrückt. As a result, the activation device can exert a force on the retaining element after activation such that the retaining element is separated from the carrier along the predetermined breaking point, in particular together with the movement-generating device. In particular, a clamping element which can be fastened to the carrier in such a manner that it presses a contact region of the movement-generating device against the holding element and in particular covers or closes the passage opening serves to fix the movement-generating device in that passage opening of the holding element. In the process, that abutment region is pressed in particular against an edge region of the bottom of the holding element which borders the passage opening.
Bevorzugt steht vom Klemmelement zumindest ein Bolzen ab, der zum Festlegen des Trägers am Klemmelement eine zugeordnete Öffnung des Trägers durchgreift, wobei jener Bolzen insbesondere mit einer Mutter verschraubt sein kann, die den Träger gegen das Klemmelement presst. Zudem kann jenes Klemmelement als ein Diffusor zum Verwirbeln in den Gassack einzuleitender Gase eingerichtet und vorgesehen sein und kann hierzu einen kappenförmigen Bereich mit Durchbrüchen aufweisen, durch die das Gas in den Gassack gelangen kann. At least one bolt preferably protrudes from the clamping element, which engages through an associated opening of the carrier for fixing the carrier to the clamping element, wherein that pin can in particular be screwed to a nut which presses the carrier against the clamping element. In addition, that clamping element can be set up and provided as a diffuser for swirling gases to be introduced into the airbag, and for this purpose can have a cap-shaped region with openings through which the gas can pass into the airbag.
Bei dem erfindungsgemäßen Airbagmodul ist der besagte Träger insbesondere dazu ausgebildet, einen (weiteren) Gasgenerator zum Aufblasen des Gassackes des Airbagmoduls zu tragen. Vorzugsweise weist der Träger einen Boden und eine davon abgehende umlaufende Wand auf, wobei jener Boden insbesondere eine Generatoröffnung zur Aufnahme des besagten (weiteren) Gasgenerators aufweist. Bevorzugt ist das Halteelement an den Boden des Trägers angeformt bzw. mit diesen über eine Sollbruchverbindung verbunden. Das am Träger zunächst festgelegte Band ist insbesondere dazu eingerichtet und vorgesehen mit Funktionskomponenten des Gassackes zusammenzuwirken, mittels derer der Gassack an eine zu schützende Person angepasst werden kann. So wirkt das Band insbesondere mit zumindest einer Abströmöffnung des Gassackes zusammen, so dass der Öffnungsquerschnitt jener mindestens einen Abströmöffnung vergrößert oder verkleinert wird, wenn das Band durch das Halteelement z.B. beim Aufblasen des Gassackes freigegeben wird. In the case of the airbag module according to the invention, the said carrier is in particular designed to carry a (further) gas generator for inflating the airbag module of the airbag module. Preferably, the carrier has a bottom and a peripheral wall extending therefrom, said bottom in particular having a generator opening for receiving said (further) gas generator. Preferably, the holding element is integrally formed on the bottom of the carrier or connected thereto via a predetermined breaking connection. The band initially fixed on the carrier is in particular designed and intended to cooperate with functional components of the airbag by means of which the airbag can be adapted to a person to be protected. Thus, the band cooperates in particular with at least one outflow opening of the airbag so that the opening cross-section of that at least one outflow opening is enlarged or reduced when the band is moved by the retaining element, e.g. is released when inflating the airbag.

Figure 4 shows in connection with the remaining figures an inventive airbag module 1 in the form of a driver airbag module in a cross section, wherein main deployment direction H of a gas bag 10 of the airbag module 1, along which the gas bag unfolds when inflated in the direction of a person to be protected in the cross-sectional plane Figure 4 is located. The airbag module 1 has a covering cap 2 which covers the airbag module 10 prior to inflation (see FIG.
Der Träger 30 weist einen insbesondere kreisförmigen Boden 36 mit einer mittigen Generatoröffnung 38 zur Aufnahme des Gasgenerators G auf (in den Figuren nicht dargestellt) sowie quer zur Hauptentfaltungsrichtung H umlaufende Wand 37, die von einem äu ßersten Rand des Bodens 36 abgeht und sich entlang der Hauptentfaltungsrichtung H erstreckt. The carrier 30 has a particular circular bottom 36 with a central generator opening 38 for receiving the gas generator G (not shown in the figures) and transverse to the main deployment direction H circumferential wall 37, the of an outer edge of the bottom 36 goes out and extends along the main deployment direction H.
An jenem Boden 36 des Trägers 30 ist ein Halteelement 31 über eine Sollbruchverbindung V einstückig an den Träger 30 angeformt, so dass der Träger im Bereich jenes Halteelementes eine (durch das Halteelement) gebildete Vertiefung bzw. Erhebung ausbildet. D.h. das Halteelement 31 steht entgegen der Hauptentfaltungsrichtung H entlang einer Erstreckungsrichtung E vom Boden 36 des Trägers 30 ab. At that base 36 of the carrier 30, a holding element 31 is integrally formed on the carrier 30 via a predetermined breaking connection V, so that the carrier in the region of that holding element forms a depression or elevation formed by the holding element. That the holding element 31 is opposite to the main deployment direction H along an extension direction E from the bottom 36 of the carrier 30 from.
Hierbei weist das Haltelement 31 eine umlaufende Wandung 32 auf, über die es an den Boden 36 des Trägers (benachbart zur Generatoröffnung 38) angeformt ist, d.h., jene Wandung ist insbesondere über die besagte Sollbruchverbindung V an den Boden 36 des Trägers 30 angeformt. Die Wandung 32 des Halteelementes 32 selbst geht von einem Boden 34 des Halteelementes 31 ab, in dem mittig eine Durchgangsöffnung 33 zur Aufnahme einer Bewegungserzeugungsvorrichtung 50 vorgesehen ist. In this case, the holding element 31 has a circumferential wall 32, via which it is integrally formed on the bottom 36 of the carrier (adjacent to the generator opening 38), that is, that wall is in particular formed via the said predetermined breaking connection V to the bottom 36 of the carrier 30. The wall 32 of the holding element 32 itself is derived from a bottom 34 of the holding element 31, in the middle of a passage opening 33 is provided for receiving a movement generating device 50.
Die Bewegungserzeugungsvorrichtung 50 wird mittels eines Klemmelementes 60 (vgl. Figuren 1 und 2) mit einem Anlagebereich 51 gegen einen die Durchgangsöffnung 33 des Halteelementes 31 begrenzenden Randbereich 34a des Bodens 34 des Halteelementes 31 gedrückt, so dass jenes Klemmelement gleichzeitig die Bewegungserzeugungsvorrichtung 50 gegenüber dem Gassack 10 abschirmt. Hierzu kann das Klemmelement 60 im Bereich der Bewegungserzeugungsvorrichtung 50 einen Vorsprung in Richtung auf die Bewegungserzeugungsvorrichtung aufweisen, d.h.. in der Erstreckungsrichtung E, der die Bewegungserzeugungsvorrichtung in die Durchgangsöffnung 33 bzw. gegen den besagten Randbereich 34a drückt, sobald der Träger 30 am Klemmelement 60 festgelegt wird. Hierzu weist das Klemmelement 60 gemäß Figur 2 vom Klemmelement 60 in der Erstreckungsrichtung E abragende Bolzen 61 auf, die durch zugehörige Öffnungen 35 des Trägers 30 gesteckt werden und z.B. mittels Muttern 62 verschraubt werden, so dass diese den Träger 30 gegen das Klemmblech 60 vorspannen. The movement-generating device 50 is pressed by means of a clamping element 60 (cf., FIGS. 1 and 2) with an abutment region 51 against an edge region 34a of the bottom 34 of the holding element 31 delimiting the through-opening 33 of the holding element 31, so that that clamping element at the same time the movement-generating device 50 relative to the gas bag 10 shields. For this purpose, the clamping element 60 may have a projection in the direction of the motion-generating device in the region of the movement-generating device 50, ie in the extension direction E, which presses the movement-generating device into the passage opening 33 or against the edge area 34a as soon as the carrier 30 is fixed to the clamping element 60 becomes. For this purpose, the clamping element 60 according to Figure 2 from the clamping element 60 in the extension direction E projecting bolts 61 which are inserted through corresponding openings 35 of the carrier 30 and, for. be screwed by means of nuts 62, so that they bias the carrier 30 against the clamping plate 60.
Die Montage von Klemmblech 60 und Träger 30 ist exemplarisch in den Figuren 1 bis 3 dargestellt. Danach wird zunächst das Klemmblech 60 in die Abdeckkappe 2 des Airbagmoduls 1 eingelegt (der gefaltete Gassack 10 ist in den Figuren 1 und 2 nicht gezeigt). Anschließend wird der Träger 30 samt Bewegungserzeugungsvorrichtung 50 (in der Figur 3 nicht gezeigt) auf das Klemmelement 60 gelegt und wie vorstehend beschrieben montiert. Gemäß Figuren 3 und 4 bis 6 kann das Klemmblech 60 auch die Funktion eines Diffusors übernehmen. Hierzu weist das Klemmblech 60 mittig einen kappenförmigen Bereich 60a mit Durchbrüchen auf, durch die hindurch mittels des Gasgenerators G freigesetztes Gas in den Gassack 10 strömen kann. The assembly of clamping plate 60 and carrier 30 is shown by way of example in Figures 1 to 3. Thereafter, the clamping plate 60 is first inserted into the cover 2 of the airbag module 1 (the folded airbag 10 is not shown in Figures 1 and 2). Subsequently, the carrier 30 together with the movement-generating device 50 (not shown in FIG. 3) is placed on the clamping element 60 and as above described mounted. According to FIGS. 3 and 4 to 6, the clamping plate 60 can also assume the function of a diffuser. For this purpose, the clamping plate 60 in the middle of a cap-shaped portion 60a with openings through which gas released by means of the gas generator G can flow into the airbag 10.
Weiterhin drückt das Klemmblech 60 nach dem Verschrauben mit dem Träger 30 gemäß den Figuren 4 bis 6 insbesondere auch die Airbagkappe 2 gegen den Boden 36 des Trägers. Weiterhin kann auch der Gassack 10, d.h., ein umlaufender Randbereich einer Einströmöffnung des Gassackes 10 mittels des Klemmbleches 60 gegen eine Teil des Airbagmoduls 1 , insbesondere den Träger 30 gedrückt werden, um den Gassack 10 im Airbagmodul 1 zu befestigen. Furthermore, after screwing to the carrier 30 according to FIGS. 4 to 6, the clamping plate 60 presses in particular also the airbag cap 2 against the base 36 of the carrier. Furthermore, the gas bag 10, that is to say a circumferential edge region of an inflow opening of the airbag 10, can also be pressed against a part of the airbag module 1, in particular the carrier 30, by means of the clamping plate 60 in order to fasten the airbag 10 in the airbag module 1.
Die Bewegungserzeugungsvorrichtung 50 ist insbesondere als ein sogenannter Mikrogasgenerator ausgebildet, der elektrisch durch eine geeignete Steuereinrichtung gezündet (ausgelöst) werden kann und dann pyrotechnisch eine Beschleunigung bereitstellt. Diese wirkt so, dass die Bewegungserzeugungsvorrichtung 50 auf das Halteelement 31 eine Kraft überträgt, die die Sollbruchverbindung V durchreißen lässt, und das Halteelement 31 entgegen der Hauptentfaltungsrichtung H, und zwar in der Erstreckungsrichtung E, vom Boden 36 des Trägers 30 absprengt. The movement-generating device 50 is designed in particular as a so-called microgas generator, which can be ignited (triggered) electrically by a suitable control device and then pyrotechnically provides an acceleration. This acts so that the movement generating device 50 transmits to the retaining element 31 a force which ruptures the predetermined breaking connection V, and the retaining element 31 against the main deployment direction H, in the extension direction E, from the bottom 36 of the carrier 30 breaks.
Hierdurch wird ein Band 20, das ausgehend vom Gassack 10 insbesondere durch die Generatoröffnung 38 geführt ist und um das Halteelement 31 , und zwar um dessen Wandung 32, herumgelegt ist, so dass ein Zug auf das Band 20 in der Hauptentfaltungsrichtung H das Band 20 gegen die Wandung 32 des Halteelementes 31 drückt und somit am Träger 30 festlegt, vom Halteelement 31 gelöst und mithin freigegeben. In this way, a band 20, which is guided starting from the airbag 10, in particular through the generator opening 38 and around the holding element 31, namely around the wall 32, is laid around, so that a train on the belt 20 in the main deployment direction H, the band 20 against the wall 32 of the retaining element 31 presses and thus determines the carrier 30, released from the holding element 31 and thus released.
Die Auslösung der Bewegungserzeugungsvorrichtung 50 ist in der Figur 5 schematisch durch einen Blitz gekennzeichnet, wobei in der Figur 5 das Halteelement 31 bereits vom Träger 30 abgetrennt ist. The triggering of the movement-generating device 50 is schematically indicated in FIG. 5 by a flash, wherein in FIG. 5 the holding element 31 has already been separated from the carrier 30.
Hierdurch wird das Band gemäß Figur 6 freigegeben, dass hier beispielsweise eine längs erstreckte Gestalt aufweist, mit einem freien Ende in Form einer geschlossenen Schlaufe 21 , die anfangs um das Halteelement 31 bzw. dessen Wandung 32 herumgelegt ist, so dass jene Schlaufe das Halteelement 31 im Querschnitt umläuft. Ein anderes freies Ende F wirkt mit dem Gassack 10 zusammen. Z.B. kann das andere freie Ende F des Bandes 20 gemäß Figur 7 an einer Abdeckung für eine Abströmöffnung 100 des Gassackes 10 befestigt sein oder selbst eine solche Abdeckung bilden, so dass das Band 20 beim Aufblasen des Gassackes 10 gespannt wird und jene Abdeckung (freies Ende F) zum Abströmen von Gas aus dem Gassack 10 von jener Abströmöffnung 100 wegzieht, sofern nicht die Bewegungserzeugungsvorrichtung 50 zum Entspannen des Bandes 20 ausgelöst wird und jenes Band 20 freigibt. Hierbei kann das freie Ende F zunächst an der Abströmöffnung 100 geeignet befestigt sein, z.B. mittels einer Reißnaht R, einer Klebeverbindung oder einer sonstigen Verbindung. Das freie Ende F (Abdeckung) kann dabei sowohl innen am Gassack 10 festgelegt sein als auch teilweise außerhalb des Gassackes 10, wozu es ggf. aus der Ausströmöffnung 100 herausgeführt ist. Wird das Halteelement 31 beim Aufblasen des Gassackes 10 nicht abgelöst, so wird das Band 20 beim Aufblasen des Gassackes 10 vorgespannt und das freie Ende F (Abdeckelement) wird von der Abströmöffnung 100 abgetrennt, wobei die besagte Verbindung R gelöst wird. Auf diese Weise ist ein steuerbares Entlüften des Gassackes 10 möglich. As a result, the band is released according to Figure 6, that here, for example, has an elongated shape, with a free end in the form of a closed loop 21, which is initially wrapped around the support member 31 and its wall 32 so that that loop, the support member 31st circulates in cross section. Another free end F cooperates with the gas bag 10. For example, the other free end F of the belt 20 may be attached according to Figure 7 to a cover for a discharge opening 100 of the airbag 10 or even form such a cover, so that the tape 20 is stretched during inflation of the airbag 10 and that cover (free end F) for the outflow of gas from the airbag 10 moves away from that outflow opening 100, unless the movement generating device 50 is triggered to relax the band 20 and releases that band 20. In this case, the free end F may initially be suitably fastened to the outflow opening 100, for example by means of a tear seam R, an adhesive bond or another connection. The free end F (cover) can be defined both on the inside of the airbag 10 and partially outside the airbag 10, for which purpose it may be led out of the outflow opening 100. If the retaining element 31 is not detached during the inflation of the gas bag 10, then the band 20 is pretensioned when the gas bag 10 is inflated and the free end F (cover element) is separated from the outlet opening 100, said compound R being released. In this way, a controllable venting of the airbag 10 is possible.
Andere Steuerungsmechanismen, bei denen der Gassack 10 mittels des Bandes 20 an eine zu schützende Person oder sonstige Umstände angepasst wird, sind ebenfalls denkbar. Other control mechanisms in which the airbag 10 is adapted by means of the belt 20 to a person to be protected or other circumstances, are also conceivable.
