Description
Die Erfindung betrifft eine Einrichtung für bei Aufprallunfällen energieumwandelndverformbare Karosseriebereiche von Kraftfahrzeugen gemäß dem Oberbegriff des Anspruches 1.The The invention relates to a device for energy-transforming deformable body regions in collision accidents of motor vehicles according to the preamble of 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.Around the occupant of a vehicle, in particular a motor vehicle in the event of a collision accident, the greatest possible protection against injury To secure it is known and in use in the bodywork Integrate structures that occur in a collision accident Impact energy or Impact energy at least to a very considerable extent in work convert mainly 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 necessary for the conversion of or rear impact occurring impact or impact energy determined are, by so-called in the front and rear of the vehicle body integrated crumple zones formed, wherein in many cases a box-shaped Hollow profile existing side rail at least one Part of their length are provided with predetermined kinks, so that one on the front or rear end impact energy acting a controlled Folding the respective side members results.

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.Based on the occupant protection in a side impact, the previously known become proposals mainly in the arrangement additional carrier in the door body and / or in the arrangement of foam padding, also mostly in the door body. Both activities to lead also to a comparatively considerable increase in vehicle weight.

der gattungsgemäßen
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine gattungsgemäße Einrichtung so zu gestalten, dass eine hohe Sicherheit für Personen erzielt wird.Based on this state of the art the invention has for its object to make a generic device so that a high level of security for people is achieved.
Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst.These The object is achieved by the achieved in claim 1 features.
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 Fahrzeuges 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 deren 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 sich prädestinierten Karosserielängsträgern oder den Schwellern der Karosserie, ein weites Feld der Anwendung, insbesondere innerhalb großflächige Strukturbereiche umgrenzender Karosseriebereiche, wie beispielsweise Seitenwandteile, Türkörper oder Karosseriebaugruppen miteinander verbindende Baugruppen.In front all a form of realization in which the with an internal pressure actable deposits are formed by gas bags, which only dependent on from a collision accident of the vehicle by means of pressure accumulator or gas generators are subjected to an internal pressure, opens a number of possibilities the deformation stiffness selectable cavities to increase surrounding body areas without them yourself must be gas-tight. It then follows that beside the increase the number of stiffenable deformation structures of the body also their simplified production is made possible. This results, that the cavities defined by body areas no more than closed gas-tight chamber executed Need to become. Thus opened next to the use in the for an application of employable with an internal pressure deposits predestined in itself Body longitudinal beams or the sills of the bodywork, a wide field of application, in particular within large-scale structural areas surrounding body areas, such as sidewall parts, Door body or body assemblies interconnecting modules.
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.Besides that is advantageous that the Deposits are effective only at the moment of impact, light (eg by gas bags) are feasible and at best a negligible weight increase entail.
