Description
Die Erfindung bezieht sich auf ein Knie-Airbagmodul eines Kraftfahrzeuges mit einem mindestens einen Airbag aufnehmenden Gehäuse, das auf der Fahrerseite unterhalb einer Armaturentafel befestigt ist.The invention relates to a Knee airbag module of a motor vehicle with at least one Airbag housing, which is attached to the driver's side below a dashboard is.
Aus der Praxis ist es bekannt, dass ein Airbag in einem Kraftfahrzeug in einem bestimmten dafür vorgesehenen Airbaggehäuse im zusammengefalteten Zustand aufbewahrt wird, um sich im Falle eines Aufprallunfalles des Kraftfahrzeuges durch Druckgasbeaufschlagung schlagartig zu entfalten und somit einen Insassen vor Verletzungen beim Aufprall auf ein Armaturenbrett, Lenkrad oder dergleichen zu schützen.It is known from practice that an airbag in a motor vehicle in a designated intended airbag housing kept in the folded state to be in case an impact accident of the motor vehicle due to pressurized gas to unfold suddenly and thus an occupant from injury in the event of an impact on a dashboard, steering wheel or the like protect.
Die
Aus der
Es ist Aufgabe der Erfindung, ein Knie-Airbagmodul der eingangs genannten Art zu schaffen, dessen Befestigung verbessert ist.It is an object of the invention To create knee airbag module of the type mentioned, whose Attachment is improved.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass das Gehäuse an einem Strukturquerträger der Fahrzeugkarosserie unterhalb eines Halters einer Lenksäule brückenartig festgelegt ist.According to the invention the object is achieved in that the housing on a structural cross member the vehicle body below a bracket of a steering column bridge-like is set.
Durch die Anbindung des Gehäuses an den Strukturquerträger der Fahrzeugkarosserie wird eine starre und stabile Verbindung zwischen dem Gehäuse und der Fahrzeugkarosserie geschaffen. Somit können bei einem Aufprallunfall sämtliche Verzögerungskräfte, auch von schweren Bauteilen des Knie-Airbagmoduls, zuverlässig aufgefangen werden. Außerdem treten keine Relativbewegungen zwischen dem Gehäuse und der Fahrzeugkarosserie auf, so dass störende Quietschgeräusche oder dergleichen ausgeschlossen sind. Die brückenartige Befestigung des Gehäuses stellt eine Anbindung in steifen Bereichen des Strukturquerträgers sicher und gewährleistet überdies eine Anordnung im unmittelbaren Bereich der unteren Extremitäten des Fahrers zum Schutz derselben. Die bei einer Auslösung und einer damit verbundenen Entfaltung des Airbags auftretenden Kräfte werden ohne unzulässige Belastung des Strukturquerträgers wirksam in die Fahrzeugstruktur eigeleitet. Darüber hinaus ist durch die brückenartige Anordnung des Gehäuses unterhalb des Halters eine störungsfreie Entfaltung des Airbags gegeben.By connecting the housing to the structural cross member the vehicle body becomes a rigid and stable connection between the housing and created the vehicle body. Thus, in the event of an impact all Delay forces, too heavy components of the knee airbag module, reliably caught become. Moreover there are no relative movements between the housing and the vehicle body, so annoying squeaking or the like are excluded. The bridge-like attachment of the housing ensures a connection in stiff areas of the structural cross member and also ensures an arrangement in the immediate area of the lower extremities of the Driver to protect them. The one with a trigger and a related The deployment of the airbag forces are without undue stress on the Structure cross member effectively introduced into the vehicle structure. In addition, the bridge-like Arrangement of the housing underneath the holder a trouble-free The airbag is deployed.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist das Gehäuse mittels zwei Haltelaschen an dem Strukturquerträger befestigt. Die beiden Haltelaschen positionieren das Gehäuse des Knie-Airbagmoduls derart, dass ein möglichst zuverlässiger Schutz für die unteren Extremitäten des Fahrers gegeben ist und bewirken gleichzeitig eine optimale Kraftübertragung beim Auslösen des Airbags.According to an advantageous embodiment the invention is the housing attached to the structural cross member by means of two retaining straps. The two retaining tabs position the housing of the knee airbag module in such a way that the most reliable protection possible for the lower extremities the driver is given and at the same time effect optimal power transmission when triggered of the airbag.
Vorteilhafterweise sind die beiden Haltelaschen links und rechts neben dem Halter der Lenksäule angeordnet. Zweckmäßigerweise sind die beiden Haltelaschen symmetrisch zu dem Halter der Lenksäule ausgerichtet. Auf diese Weise wird eine optimale Anordnung und Ausrichtung des Gehäuses sowie des Airbags in Bezug zu der Position des zu schützenden Fahrers sichergestellt.The two are advantageous Holding brackets arranged on the left and right next to the holder of the steering column. Conveniently, the two retaining tabs are aligned symmetrically to the holder of the steering column. In this way, an optimal arrangement and orientation of the Housing as well of the airbag in relation to the position of the driver to be protected.
Zur zuverlässigen Festlegung der Haltelaschen sind vorteilhafterweise die Haltelaschen zumindest in dem dem Strukturquerträger zugeordneten Befestigungsbereich mit zwei gegenüberliegenden Schenkeln versehen, die eine Wandung des Strukturquerträgers übergreifen. Auf die Haltelaschen einwirkende Momente bei einem Aufprallunfall werden über die Schenkel in die Wandung des Strukturquerträgers eingeleitet. Bevorzugt sind die beiden Haltelaschen an dem Strukturquerträger angeschweißt.In order to reliably fix the retaining straps, the retaining straps are advantageously provided with two opposing legs, at least in the fastening area assigned to the structural cross member, which overlap a wall of the structural cross member. Moments acting on the retaining tabs in the event of an impact are introduced into the wall of the structural cross member via the legs. The two retaining tabs are preferably attached to the structural cross member welded.
Nach einer Weiterbildung des Erfindungsgedankens weisen die Haltelaschen einen biegesteifen S-förmigen Verlauf auf und erstrecken sich ausgehend von dem Strukturquerträger in Richtung eines Fahrersitzes. Durch unterschiedliche Gestaltung der Radien der S-Form können der Abstand des Gehäuses zu den unteren Extremitäten des Insassen und die Schussrichtung des Airbags variiert werden.After a further development of the inventive idea the retaining tabs have a rigid S-shaped course and extend starting from the structural cross member towards a driver's seat. By different design of the radii of the S shape, the Distance of the housing to the lower extremities of the occupant and the direction of fire of the airbag can be varied.
Um eine breite Abstützung und damit eine geringe Belastung des Gehäuses sicherzustellen, sind an den Haltelaschen an dem dem Gehäuse zugewandten Ende Befestigungsflansche für das Gehäuse angeformt. Zur sicheren Festlegung ist das Gehäuse mittels Schrauben an den Haltelaschen befestigt. Zweckmäßigerweise umfasst das Gehäuse zur Verschraubung mit den Haltelaschen beidseitig biegesteif angeformte Flansche.To provide broad support and to ensure a low load on the housing on the retaining tabs on the end facing the housing mounting flanges for the casing formed. To secure it in place, the housing is attached to the Retaining tabs attached. Conveniently, includes the housing for Screwed to the retaining straps on both sides Flanges.
Zur zusätzlichen Abstützung sowohl in der Kraftbeaufschlagungsrichtung als auch in Fahrzeugquerrichtung weist vorzugsweise das Gehäuse jeweils endseitig Rücksprünge für die Haltelaschen auf.For additional support both in the direction of application of force as well as in the transverse direction of the vehicle preferably has the housing recesses for the retaining tabs on each end.
Vorteilhafterweise weist das Gehäuse bei verschiedenen Kraftfahrzeugen derselben Plattform dieselben Abmessungen auf. Somit muss das Gehäuse bei einer gemeinsamen Plattform für verschiedene Fahrzeuge nur einmal entwickelt werden, wodurch Entwicklungskosten und Entwicklungszeiten eingespart werden.Advantageously, the housing has different Motor vehicles of the same platform have the same dimensions. Consequently must the housing with a common platform for different vehicles only be developed once, which saves development costs and development times become.
