Description
Die Erfindung betrifft eine Einrichtung für bei Aufprallunfällen energieumwandelndverformbare Karosseriebereiche von Kraftfahrzeugen gemäß dem Anspruches 1.The invention relates to a device for energy-transforming deformation-deformable body regions of motor vehicles according to claim 1.
Um den Insassen eines Fahrzeuges, insbesondere eines Kraftfahrzeuges bei einem Aufprallunfall einen größtmöglichen Schutz vor Verletzungen zu sichern ist es bekannt und gebräuchlich in den Karosserieverband Strukturen zu integrieren, welche die bei einem Aufprallunfall auftretende Stoßenergie bzw. Aufprallenergie wenigstens zu einem sehr erheblichen Teil in Arbeit umwandeln und zwar hauptsächlich in Verformungsarbeit umwandeln.In order to ensure the greatest possible protection against injury to the occupants of a vehicle, in particular a motor vehicle in a collision accident, it is known and commonly integrated into the bodywork structures that convert the impact energy or impact energy occurring in a collision accident at least to a very considerable extent in work and mainly to transform into deformation work.
Solche Strukturen sind, soweit sie zur Umwandlung der bei einem Front- oder Heckaufprall auftretenden Stoß- bzw. Aufprallenergie bestimmt sind, durch sogenannte in den Vorder- und Hinterwagen der Fahrzeugkarosserie integrierte Knautschzonen gebildet, wobei in vielen Fällen aus einem kastenförmigen Hohlprofil bestehende Längsträger zumindest über einen Teil ihrer Länge hin mit Sollknickstellen versehen sind, derart daß eine auf den Vorder- oder Hinterwagen wirkende Aufprallenergie eine kontrollierte Faltung der jeweiligen Längsträger ergibt.Such structures, insofar as they are intended for converting the impact or impact energy occurring in the event of a front or rear impact, are formed by so-called crumple zones integrated in the front and rear bodies of the vehicle body, wherein in many cases longitudinal members consisting of a box-shaped hollow profile overlap at least a part of their length are provided with predetermined kinks, so that an acting on the front or rear impact energy results in a controlled folding of the respective side members.
Darüber hinaus ist es dann auch bekannt (
Schließlich besteht eine weitere bekannte Variante (
Bezogen auf den Insassenschutz bei Seitenaufprall bestehen die bisher bekannt gewordenen Vorschläge hauptsächlich in der Anordnung zusätzlicher Träger im Türkörper und/oder in der Anordnung von Schaumstoffpolsterungen, gleichfalls meist im Türkörper. Beide Maßnahmen führen ebenfalls zu einer vergleichsweise beachtlichen Erhöhung des Fahrzeuggewichtes.Relative to the occupant protection in the event of a side impact, the previously known proposals consist mainly in the arrangement of additional carriers in the door body and / or in the arrangement of foam padding, likewise usually in the door body. Both measures also lead to a comparatively considerable increase in vehicle weight.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung so zu gestalten, dass eine hohe Sicherheit für Personen erzielt wird.The invention has for its object to make a device so that a high level of security for people is achieved.
Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in claim 1.
Vorteilhafte Ausgestaltungen und Weiterbildungen sind in den Unteransprüchen angegeben.Advantageous embodiments and further developments are specified in the subclaims.
Vor allem eine Verwirklichungsform, bei der die mit einem Innendruck beaufschlagbaren Einlagen durch Gassäcke gebildet sind, welche lediglich in Abhängigkeit von einem Aufprallunfall des Fahrzeugs vermittels Druckspeicher oder Gasgeneratoren mit einem Innendruck beaufschlagt werden, eröffnet eine Reihe von Möglichkeiten, die Verformungssteifigkeit auswählbarer Hohlräume umgrenzender Karosseriebereiche zu erhöhen, ohne dass diese selbst gasdicht sein müssen. Daraus folgt dann, dass neben der Erhöhung der Anzahl der aussteifbaren Verformungsstrukturen der Karosserie auch der vereinfachte Herstellung ermöglicht wird. Daraus resultiert, dass die von Karosseriebereichen umgrenzten Hohlräume nicht mehr als geschlossene gasdichte Kammer ausgeführt werden müssen. Somit eröffnet sich neben dem Einsatz in den für eine Anwendung von mit einem Innendruck beaufschlagbaren Einlagen an Knotenteilen bzw. Knotenelementen, die Längsträger der Tragstruktur eines Vorderwagens und/oder eines Hinterwagens mit der Tragstruktur der Fahrgastzelle verbinden, ein weites Feld der Anwendung, insbesondere innerhalb großflächige Strukturbereiche umgrenzender Karosseriebereiche, wie beispielsweise Seitenwandteile, Türkörper oder Karosseriebaugruppen miteinander verbindende Baugruppen.Above all, a realization form in which the deposits which can be acted upon with an internal pressure are formed by gas bags which are subjected to an internal pressure only as a function of an impact accident of the vehicle by means of pressure accumulators or gas generators opens up a number of possibilities, the deformation stiffness of selectable cavities of surrounding body regions increase, without these themselves must be gas-tight. It follows then that in addition to increasing the number of stiffenable deformation structures of the body and the simplified production is made possible. As a result, the cavities bounded by body regions no longer have to be designed as a closed gas-tight chamber. Thus, in addition to the use in the applicable for an application of with an internal pressure deposits on node parts or node elements that connect the longitudinal beams of the support structure of a front and / or a rear carriage with the support structure of the passenger compartment opens up a wide field of application, especially within large areas Structural areas of surrounding body areas, such as side wall parts, door body or body assemblies interconnecting assemblies.
Außerdem ist vorteilhaft, daß die Einlagen lediglich im Augenblick des Aufpralls wirksam sind, leicht (bspw. durch Gassäcke) realisierbar sind und dabei allenfalls eine vernachlässigbare Gewichtserhöhung nach sich ziehen.It is also advantageous that the deposits are effective only at the moment of impact, easily (eg. By gas bags) are feasible and at best pull a negligible increase in weight.
