Description

Die Erfindung betrifft einen Türinnenmodul gemäß dem Oberbegrifft des Patentanspruchs 1.The invention relates to an inner door module according to the generic term of Claim 1.

Bei Kraftfahrzeugen der Anmelderin sind Türinnenmodule mit Inseris im Einsatz, die aus mehreren Teilen bestehen. Im Bereich der Ausnehmung des Innenverkleidungsteils befindet sich dabei ein Formteil aus ABS, das mit einem Dekor versehen ist. Oberhalb der besagten Ausnehmung enthält der Insert einen ein selbständiges Teil darstellenden Bereich aus PUR-Schaum, während sich unterhalb des ersterwähnten, hinter der Ausnehmung liegenden Bereichs ein ebenfalls ein eigenes Teil bildender Bereich aus EPP-Schaum erstreckt, der also ebenfalls hinter dem Innenverkleidungsteil liegt. EPP ist bekanntlich die Abkürzung für Aethylen-Polypropylen.In the applicant's motor vehicles, door interior modules with inser are in use, which are made of consist of several parts. In the area of the recess of the interior trim part there is a molded part made of ABS, which is provided with a decor. Above the said recess contains an insert which represents an independent part Area of PUR foam, while below the first mentioned, behind the Recess area from an area also forming a separate part EPP foam extends, which is also behind the interior trim part. Is EPP As is well known, the abbreviation for ethylene polypropylene.

Wie schon diese Beschreibung erkennen läßt, ist die Herstellung des Inserts bei diesem bekannten Türinnenmodul sehr aufwendig und kostenintensiv. Der Erfindung liegt demgemäß die Aufgabe zugrunde, einen gattungsgemäßen Türinnenmodul zu schaffen, der bei wirksamem Schutz der Fahrzeuginsassen gegen Verletzungen bei einem Seitencrash einfach und kostengünstig herzustellen ist.As can already be seen from this description, the manufacture of the insert is in this known door module very complex and expensive. The invention lies accordingly the task of creating a generic door interior module, the effective protection of vehicle occupants against injuries in a Side crash is easy and inexpensive to manufacture.

Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Hauptanspruchs, eine vorteilhafte Ausbildung der Erfindung beschreibt der Unteranspruch.The inventive solution to this problem consists in the characterizing Features of the main claim describes an advantageous embodiment of the invention the subclaim.

Da alle bisher als selbständige Teile gefertigten Bereiche des Inserts erfindungsgemäß einteilig und aus einem einzigen Material, nämlich EPP-Partikelschaum, bestehen, ist der Aufwand für Herstellung und Montage auf ein Minimum reduziert. Die Auswahl speziell von EPP-Partikelschaum bringt eine Reihe von Vorteilen mit sich: Zum einen ergibt dieses Material, das innen geschlossene Zellen sowie eine diese umgebende geschlossene Außenhaut bildet, den Vorteil eines hochwirksamen Schutzes der Fahrzeuginsassen bei einem Seitencrash, zumal das Energieabsorptionsvermögen der verschiedenen Bereiche des Inserts beispielsweise durch Aussparungen eingestellt werden kann, wobei die Energieabsorption in Abhängigkeit vom Deformationsweg gleichsam durch gezieltes Zusammenbrechen von Aussparungen gesteuert wird. Ein weiterer Vorteil dieses Materials ist darin zu sehen, daß eine Stoffkaschierung leicht in der Weise herstellbar ist, daß der Stoff in das Heizpreßwerkzeug für den EPP- Partikelschaum eingelegt, EPP als Granulat eingebracht und dann durch Wärmeeinwirkung bei Temperaturen um 175°C und Druckanwendung eine Verbindung zwischen dem Stoff und dem Kunststoffmaterial hergestellt wird. Es kommt also gleichsam zum Verschweißen des Kunststoffkörpers des Inserts mit dem Stoff.Since all areas of the insert previously manufactured as independent parts according to the invention is made in one piece and from a single material, namely EPP particle foam Manufacturing and assembly costs reduced to a minimum. The selection specifically EPP particle foam has a number of advantages: this material, the cells that are closed on the inside and a surrounding cell  closed outer skin forms the advantage of a highly effective protection of the Vehicle occupants in a side crash, especially since the energy absorption capacity of the different areas of the insert are set, for example, by cutouts can be, the energy absorption depending on the deformation path is controlled as it were by deliberately collapsing recesses. On Another advantage of this material is the fact that a fabric lamination is easy which can be produced in such a way that the substance is inserted into the heating press tool for the EPP Particle foam inserted, EPP introduced as granules and then through Exposure to heat at temperatures around 175 ° C and application of pressure is made between the fabric and the plastic material. So it comes as it were for welding the plastic body of the insert to the fabric.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung erläutert, die in Explosionsdarstellung perspektivisch schräg vom Innenraum des Fahrzeugs her eine entsprechend ausgeführte Kraftfahrzeug-Seitentür zeigt.An embodiment of the invention is described below with reference to the drawing explained, the perspective exploded obliquely from the interior of the Vehicle ago shows a correspondingly designed motor vehicle side door.

Die dargestellte Tür besteht im wesentlichen aus drei Hauptgruppen, nämlich der Türaußenblechanordnung 1 mit Funktionsträgern und dergleichen (der an sich bekannte Aufbau interessiert für die Erfindung im einzelnen nicht), dem Innenverkleidungsteil 2, das rahmenartig mit der Ausnehmung 3 versehen und aus einem harten Kunststoff, beispielsweise ABS mit einer PVC-Folie besteht, zwischen diesen beiden den Türabschluß nach außen bzw. innen bildenden Baugruppen 1 und 2 liegt der Insert 4 mit den drei Bereichen 5, 6 und 7, von denen die beiden Bereiche 5 und 6 von innen betrachtet hinter dem Innenverkleidungsteil 2 (und selbstverständlich vor dem Außenblech 1) liegen, während der mittlere Bereich 7 vom Innenraum des Fahrzeugs her durch die Ausnehmung 3 zugänglich ist und beispielsweise einen integrierten Türgriff bildet. Alle drei Bereiche 5, 6 und 7 sind erfindungsgemäß einteilig aus EPP- Partikelschaum hergestellt; der mittlere Bereich 7 ist mit einer Folie oder bevorzugt mit einem Stoff kaschiert, wobei die Stoffkaschierung in der eingangs beschriebenen Weise bei der Formgebung des Inserts 4 aufgebracht ist.The door shown consists essentially of three main groups, namely the door outer panel arrangement 1 with functional supports and the like (the known structure is of no interest to the invention in detail), the inner trim part 2 , which is provided with the recess 3 in a frame-like manner and made of a hard plastic, for example ABS with a PVC film, between these two modules 1 and 2 forming the door closure to the outside or inside is the insert 4 with the three areas 5 , 6 and 7 , of which the two areas 5 and 6, viewed from the inside, are behind the interior trim part 2 (and of course in front of the outer panel 1 ), while the central area 7 is accessible from the interior of the vehicle through the recess 3 and forms, for example, an integrated door handle. According to the invention, all three areas 5 , 6 and 7 are made in one piece from EPP particle foam; the middle area 7 is laminated with a film or preferably with a fabric, the fabric lamination being applied in the manner described at the outset when the insert 4 is shaped.

Das verwendete Material, also EPP-Partikelschaum, hat einerseits gute Deformationseigenschaften zur Energieumsetzung bei einem Seitencrash, ist also wirksam als Insassenschutz, und besitzt andererseits bei Deformationen mit einem niedrigeren Energieniveau, wie sie beispielsweise mittels der Hand, hervorgerufen werden können, ein gutes Rückstellvermögen in seine ursprüngliche Form.The material used, i.e. EPP particle foam, has good properties Deformation properties for energy conversion in a side crash, is therefore effective as occupant protection, and on the other hand has deformations with a  lower energy levels, such as those caused by the hand can be a good resilience in its original form.

Zur Steuerung des Deformationsverhaltens bei einem Crash können einzelne Zonen des Inserts 4 mit Ausnehmungen 8 versehen sein, die dafür sorgen, daß von einem bestimmten Deformationsgrad an sich ihre Ränder aufeinanderlegen, demgemäß also die Ausnehmungen verschwinden und dadurch eine mehr oder wenige sprungartige Erhöhung der Steife des Inserts 4 hervorgerufen wird.To control the deformation behavior in a crash, individual zones of the insert 4 can be provided with recesses 8 , which ensure that their edges lie on each other from a certain degree of deformation, accordingly the recesses disappear and thereby a more or less abrupt increase in the stiffness of the Inserts 4 is caused.

Mit der Erfindung ist demgemäß ein gattungsgemäßer Türinnenmodul geschaffen, der einerseits besonders vorteilhaft hinsichtlich seiner Herstellung einschließlich Montage, andererseits aber auch hochwirksam im Betrieb ist, nämlich bei der Minimierung der Folgen von Seitencrashs.The invention accordingly creates a generic door interior module that on the one hand, particularly advantageous with regard to its manufacture including assembly, on the other hand, it is also highly effective in operation, namely in minimizing the Sequences of side crashes.
