Abstract

A frame-shaped three-dimensional moulding of e.g. plastic or compressed cardboard has an upper part (1), a lower part (2), front and rear sides (3,4) and an armrest (5) whose free end is joined by a handgrip (6) to the upper part in the region of an opening (7) for operation of the lock. At the lower front corner a covering (8) is provided for a loudspeaker. Shock-absorbing properties are improved by slits (9) in some surfaces, at right angles to the longitudinal axis of the vehicle. ADVANTAGE - The energy absorption in a collision is improved without need to use different materials or increase mfg. costs.

Description

Die Erfindung betrifft ein Innenverkleidungsteil gemäß dem Ober­ begriff des Patentanspruchs 1.The invention relates to an interior trim part according to the upper Concept of claim 1.

Aus der DE 33 36 934 C2 ist ein Armaturenbrett für Kraftfahrzeuge bekannt, das zwei übereinander angeordnete Schaumstoffkörper mit unterschiedlichen Raumgewichten und Stauchhärten enthält. Durch den Einsatz unterschiedlicher Materialien wird damit eine Abdeckung geschaffen, die einerseits formbeständig ist und anderer­ seits komfortverbessernde bzw. verletzungsmindernde Eigenschaften besitzt.DE 33 36 934 C2 is a dashboard for motor vehicles known that the two superimposed foam body with contains different densities and compression hardness. By the use of different materials thus becomes a cover created, which on the one hand is dimensionally stable and on the other on the one hand comfort-improving or injury-reducing properties owns.

Weiterhin ist aus der DE 37 42 233 A1 ein Innenabdeckteil für ein insbesondere aus Blech bestehendes Karosserieteil bekannt, wel­ ches (Innenabdeckteil) eine einstellbare, berechenbare Nachgie­ bigkeit und Elastizität durch auf der Rückseite angeordnete un­ terschiedlich bemessene Vorsprünge aufweist, mit denen es auf dem Karosserieteil aufliegt. Solch ein Innenabdeckteil herzustellen, ist aufwendig.Furthermore, from DE 37 42 233 A1 an inner cover part for a especially known from sheet metal body part, wel ches (inner cover part) an adjustable, predictable Nachgie elasticity and elasticity due to un arranged on the back Has different sized projections with which it on the Body part rests. To make such an inner cover part is complex.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes In­ nenverkleidungsteil im Hinblick auf eine bessere Energieaufnahme beim Crash und auf eine bessere Haptik zu optimieren. Dabei sol­ len weder unterschiedliche Materialien verwendet werden müssen, noch soll das Herstellungsverfahren aufwendig sein. The invention has for its object a generic In Inner trim part with a view to better energy absorption in the event of a crash and to optimize the haptics. Thereby sol len neither need to use different materials, the manufacturing process should still be complex.  

Erfindungsgemäß wird diese Aufgabe mit den kennzeichnenden Merk­ malen des Patentanspruchs 1 gelöst.According to the invention this task with the characteristic note paint the claim 1 solved.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of Subclaims.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung, in der eine als Preßteil hergestellte Türverkleidung für ein Kraftfahrzeug dargestellt ist, näher erläutert.An embodiment of the invention is shown in the drawing, in which a door panel manufactured as a pressed part for a Motor vehicle is shown, explained in more detail.

Die Türverkleidung ist ein im wesentlichen rahmenförmiges, drei­ dimensionales Formteil, beispielsweise aus Kunststoff oder Preß­ pappe, mit einem Oberteil 1, einem Unterteil 2, einem vorderen Seitenteil 3 und einem hinteren Seitenteil 4, an dem eine Arm­ stützen 5 angeformt ist, deren freies Ende mittels eines Zuzieh­ griffes 6 mit dem Oberteil 1 im Bereich einer Aussparung 7 für eine Schloßbetätigung verbunden ist. Im vorderen unteren Eckbe­ reich der Türverkleidung ist eine Abdeckung 8 für einen Lautspre­ cher vorgesehen. Solche Bereiche der an sich formsteifen Türver­ kleidung, die aus Sicherheitsgründen eine größere Nachgiebigkeit erfordern, im Ausführungsbeispiel das Oberteil 1 und die Armstüt­ ze 5, sind mit gleichgerichteten, im wesentlichen quer zur Fahr­ zeuglängsachse verlaufenden Schlitzen 9 versehen, die eine ge­ zielte Weichheit der Türverkleidung begründen, so daß die Türver­ kleidung im Crashfall dazu beitragen kann, einen Teil der Auf­ prallenergie abzubauen. Ohne daß die Wirksamkeit der Schlitze 9 spürbar beeinträchtigt wird, können diese von innen oder außen mit einer Folie abgedeckt sein.The door trim is a substantially frame-shaped, three-dimensional molded part, for example made of plastic or cardboard, with an upper part 1 , a lower part 2 , a front side part 3 and a rear side part 4 , on which an arm support 5 is formed, the free end of which by means of a pull handle 6 is connected to the upper part 1 in the region of a recess 7 for a lock actuation. In the front lower Eckbe rich of the door trim, a cover 8 is provided for a loudspeaker. Such areas of the dimensionally stable Türver clothing, which require greater flexibility for safety reasons, in the exemplary embodiment the upper part 1 and the armrest ze 5 are provided with the same, essentially transverse to the longitudinal axis of the vehicle slots 9 which provide a targeted softness of the door trim justify so that the door trim in the event of a crash can help to reduce part of the impact energy. Without the effectiveness of the slots 9 being appreciably impaired, they can be covered with a film from the inside or outside.
