Abstract

The elastic cladding (10) for the inside of the passenger compartment and the soft covering of bumpers is prepared by binding shredded or granulated rubber and plastic waste with a suitable adhesive. The waste can be from old tyres, plastic packing etc. and replaces the expensive foam cladding used conventionally. No special moulding tools are required, only simple moulds. The cladding can be used around dashboard edges or for energy absorbing bumpers and is covered with a decorative material finish.

Description

Aufbauteile für Fahrzeuge, insbesondere Kraftfahrzeuge Die Erfindung bezieht sich auf Aufbauteile für Fahrzeuge, insbesondere Kraftfahrzeuge, die aus elastischem Werkstoff bestehen und vorzugsweise energieabsorbierend ausgebildet sind. Structural parts for vehicles, in particular motor vehicles. The invention relates to structural parts for vehicles, especially motor vehicles made from consist of elastic material and preferably designed to be energy-absorbing are.

Aufbauteile der eingangs genannten Gattung sind zumeist aus Kunststoff, vorzugsweise Polyurethan, hergestellt, die aufgrund der Energieverknappung teuere Bauelemente darstellen. Ein anderes Problem ist, daß die ausgedienten Produkte (Gummi und Kunststoff), die oftmals in viel Raum beanspruchender Größe anfallen, nur unter Anwendung von komplizierten Verfahren, die zumeist umweltfeindlich sind, aufgelöst werden können. Body parts of the type mentioned are mostly made of plastic, preferably polyurethane, which is expensive due to the shortage of energy Represent components. Another problem is that the obsolete products (rubber and plastic), which often take up a lot of space, only under Use of complicated procedures, most of which are harmful to the environment, resolved can be.

Aufgabe der vorliegenden Erfindung ist es, Aufbauteile zu schaffen, mittels derer die genannten Nachteile vermieden werden. The object of the present invention is to create structural parts, by means of which the disadvantages mentioned are avoided.

Dies wird nach der Erfindung dadurch erzielt, daß die Aufbauteile aus elastischen Abfallprodukten bestehen, die mit einem Bindemittel vergossen sind. Hierfür ist es von Vorteil, wenn das Verbundmaterial, Abfallproduktteile und Bindemittel reversible Eigenschaften besitzt. Das Verbundmaterial dient zur Herstellung von Absorbern, wie bei Stoßfängern verwendet. Das Verbundmaterial dient zur Herstellung von Fahrzeuginnenteilen wie Säulenverkleidung, Armaturentafel oder dergleichen. Die Abfallproduktteile werden aus Altgummi (Reifen) gewonnen. Die Abfallproduktteile werden in gemahlener Form dem Verbundmaterial beigefügt. Die Abfallproduktteile werden als Schnitzel dem Verbundmaterial beigefügt. Außerdem wird das Bindemittel durch ein Reaktionsharz gebildet. This is achieved according to the invention in that the structural parts consist of elastic waste products that are potted with a binder. For this it is advantageous if the composite material, waste product parts and binders possesses reversible properties. The composite material is used for Manufacture of absorbers such as those used in bumpers. The composite material serves for the production of vehicle interior parts such as pillar trim, dashboard or like that. The waste product parts are obtained from old rubber (tires). The waste product parts are added to the composite material in ground form. The waste product parts are added to the composite material as chips. It also becomes the binder formed by a reaction resin.

Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, daß die Aufbauteile aus Abfallprodukten hergestellt sind, wodurch diese nicht nur preislich günstig sind, sondern auch eine sinnvolle Weiterverwendung von Abfallprodukten möglich ist. The main advantages achieved by the invention are therein to see that the superstructure parts are made from waste products, thereby eliminating them are not only inexpensive, but also meaningful further use of Waste products is possible.

In der Zeichnung werden Ausführungsbeispiele der Erfindung näher erläutert. Es zeigt Figur 1 einen Schnitt durch einen Endbereich eines Fahrzeuges, Figur 2 einen Schnitt durch eine Schalttafel, Figur 3 einen Schnitt durch eine Dachsäule. Exemplary embodiments of the invention are shown in greater detail in the drawing explained. It shows Figure 1 a section through an end area of a vehicle, FIG. 2 shows a section through a control panel, FIG. 3 shows a section through a roof pillar.

Die Endeinheit 1 des Kraftfahrzeuges gemäß Figur 1 ist an einen Aufbau 2 angegliedert, der mit einer aufrechten Wand 3 ein als Absorber 4 ausgebildetes Aufbauteil trägt. Der Absorber 4 wird von einer nachgiebigen, jedoch formbeständigen Haut 5 verkleidet. The end unit 1 of the motor vehicle according to FIG. 1 is attached to a structure 2 affiliated, which is designed as an absorber 4 with an upright wall 3 Body part carries. The absorber 4 is made of a flexible, but dimensionally stable Skin 5 disguised.

Zur Herstellung des Absorbers 5 sind elastische Abfallproduktteile vorgesehen, wie sie z.B. aus ausgedienten Gummireifen oder Kunststoffteilen entstehen. Diese Abfallproduktteile werden mit einem Bindemittel vergossen, das beispielsweise durch ein Reaktionsharz gebildet wird. Durch die genannte Zusammensetzung entsteht ein Verbundmaterial. Elastic waste product parts are used to produce the absorber 5 provided, such as those made from worn out rubber tires or plastic parts. These waste product parts are potted with a binder, for example is formed by a reaction resin. The composition mentioned arises a composite material.

Das Verbundmaterial besitzt reversible Eigenschaften, so daß der Absorber 5 sich nach erfolgter Energieaufnahme in seine Ausgangsstellung zurückbildet. The composite material has reversible properties, so that the Absorber 5 returns to its original position after energy has been absorbed.

Die Abfallproduktteile sind dem Verbundmaterial in Form von Schnitzeln 6 beigefügt. The waste product parts are the composite material in the form of chips 6 attached.

In Figur 2 ist eine Schalttafel 7 dargestellt, die einen Träger 8 umfasst, der an eine Windschutzscheibe 9 herangeführt ist. Mit dem Träger 8 ist eine Polsterung 10 verbunden, die ebenfalls aus Abfallproduktteilen hergestellt ist, wobei es in gemahlenem Zustand (grob oder feinkörnig) dem Verbundmaterial zugeführt wird (siehe Bereich A). In FIG. 2, a switchboard 7 is shown, which has a carrier 8 which is brought up to a windshield 9. With the carrier 8 is a padding 10 connected, which is also made from waste product parts it is fed to the composite material in the ground state (coarse or fine-grained) (see area A).

Die Polsterleiste 11 nach Figur 3, die einer ein Dach tragenden Säule 12 zugeordnet ist, besteht aus dem gleichen Verbundmaterial (Abfallproduktteile und Bindemittel). The upholstery strip 11 according to FIG. 3, that of a column supporting a roof 12 is assigned, consists of the same composite material (waste product parts and binders).
