Definitions
- the invention relates to a multilayer decorative structure for a vehicle interior trim part, which has at least one base layer, a decorative layer and optionally an intermediate layer arranged between these layers and which is produced by lamination.
- the present invention further relates to a vehicle interior trim part comprising a support part and a multilayer decorative structure
- Known multilayer outer linings consist, for example, of a textile, usually made of polyester, decorative layer, which preferably consists of a nonwoven fabric
- Base layer is connected by means of an adhesive by lamination. Between the decorative layer and the base layer, a haptic-improving layer made of PU foam can be introduced, which is connected to the decorative layer as well as the base layer by flame lamination. or introduced plastic mass into the base layer, which creates the connection between the outer cladding and the plastic and creates the interior trim
- an interior fitting position for vehicles which consists of a rigid molded support part and a multi-layer decorative structure of the type mentioned at the outset.
- the molded support part is connected to a non-woven layer of the decorative structure by means of a first adhesive layer
- a second layer of adhesive is located between the non-woven fabric and a decorative layer made of real leather.
- the decorative layer also consists of leather or a leather substitute.
- the decorative layer is connected to a haptic intermediate layer made of a polypropylene or polyethylene foam in the form of sheets or rolls by flame lamination or by means of separate hot-melt adhesive films.
- the decorative layer provided with the haptic intermediate layer is placed in a suitable tool and pressed in with a natural fiber thermoplastic composite, whereby the vehicle interior trim part is completed.
- decorative layers - be they made of textile materials or leather or leather substitute - are the look and feel of the surface. It is therefore important that the decor structure is designed so that its surface, the decor layer, through the printing and
- the invention has therefore set itself the task of improving the steaming effect in a multi-layer decorative structure of the type mentioned without the use of foam layers and to design the structure so that largely all, including pressure and temperature sensitive decorative layers by means of thermal Technologies that are subject to stress and take place under pressure and can be used to produce interior fittings without sacrificing quality, and that good adhesion to the carrier part can be ensured.
- Interior parts should therefore be able to be produced in high quality and in particular also with decorative structures with pressure and temperature-sensitive decorative layers
- a barrier layer of a deformable elastic material that seals the base layer and is impregnated on the surface is applied
- the barrier layer which is made of an elastic material, has a number of very advantageous properties. Its function as a sealing layer and its steaming and insulating properties are of particular importance.
- the barrier layer is of particular importance if the decorative structure is connected to the carrier part during the manufacture of a vehicle interior trim part When using a direct procedure -
- the layer of elastic material forms a connection with the plastic mass, whereby it no longer penetrates into the base layer.
- the steaming properties of the base layer can be fully retained, so that they ensure the function of the desired feel
- the barrier layer complicates the transfer of heat and absorbs pressure, so that with a decorative structure according to the invention also decorative layers made of a material that is more sensitive to pressure and heat exist, can be used without expected loss of quality
- the intermediate layer arranged between the base layer and the decorative layer also consists of a deformable and elastic material (claim 2)
- Intermediate layer in addition to its function as a connecting layer, also has a heat-insulating and pressure-absorbing effect and thus has a steaming effect
- latex, acrylic resin or a thermoplastic elastomer are particularly suitable as the starting material for the deformable elastic material (claim 3).
- the mixture composition can ensure that they have the required or desired properties with regard to temperature resistance, aging resistance, lightfastness, etc. can
- connection and sealing function as well as the elastic properties of the respective material are ensured by the fact that the corresponding starting material is used in uncured or uncured form, however in the finished decor structure the barrier layer and possibly the intermediate layer consist of the cross-linked or hardened material (claim 4)
- different starting materials can be used for the barrier layer and the intermediate layer (claim 5). This can have an influence on preferred or desired properties or functions of the layers, for example as regards their elastic and insulating properties
- the barrier layer has a layer thickness which differs from that of the intermediate layer (claim 6). This measure also allows the desired or required properties to be influenced accordingly In this case, the design is in particular such that the intermediate layer has a greater layer thickness than the barrier layer (claim 7). Thus, in addition to the base layer, the intermediate layer can also influence the feel of the decorative layer
- the base layer can be designed in multiple layers, in particular in two layers (claim 8). This opens up the possibility of accommodating additional internals between these layers. Such internals can be, for example, electrically conductive foils (claim 9).
- the ability of the barrier layer to absorb pressure and hindering the transfer of heat makes it possible for the user to accommodate additional fittings which are advantageous for the user in the decorative structure, which has not been possible hitherto, in particular because of the heat sensitivity of the materials in question
- the barrier layer provided according to the present invention and also the intermediate layer optionally provided according to the invention are each made in a layer thickness of 0.05 to 3 mm, in particular 0.5 to 1 mm.
- a minimum layer thickness is required in order to and ensure the sealing function
- a certain upper limit of the layer thickness is favorable in order not to unnecessarily increase the weight of the decorative structure.
- Layer thicknesses of up to 3 mm are generally sufficient for the desired insulating and steaming properties
- the subject invention also relates to a vehicle interior trim part comprising a shaping support part and a multi-layer decorative structure with a base layer and a decorative layer.
- a vehicle interior trim part designed according to the invention is provided with a decorative structure according to at least one of claims 1 to 10 (claim 11)
- the advantageous properties of the decorative structure mentioned above are also present in the vehicle interior trim part according to the invention, so that it is possible to provide a high-quality interior trim panel, the decorative layer of which can also consist of a pressure- or heat-sensitive material
- This vehicle interior trim part can be produced by a direct process, by back injection or back pressing (claim 12). However, production by lamination is also possible (claim 13). With both production processes, it is ensured that at the temperatures that occur and under the prevailing pressure conditions Even decorative layers sensitive to pressure and temperature retain their quality
- Vehicle interior fittings designed according to the invention are, in particular, tower cladding, pillar cladding or luggage compartment linings (claim 14). Particularly with these claddings or linings, particularly high demands are made on the decor structure, in particular as regards the quality of the material of the decorative layer, with the present invention can meet these claims Panels or linings are provided
- FIG. 1 shows a cross section through a partial area of an embodiment of a multi-layer decorative structure for a vehicle.
- Interior part shows in cross section
- FIG. 2 is a cross section through a partial area of a finished vehicle interior part, which has the decorative structure according to FIG. 1 as a component
- a vehicle interior trim part 1 designed according to the invention can be, for example, a door trim, a pillar trim or a luggage compartment trim.
- the vehicle interior trim 1 consists of a support part 2, in particular made of plastic, which forms and forms its load-bearing component, and a multilayer decorative structure 3 sub Using the multilayer decorative structure 3, the interior part can now be used in a direct process. Injection molding or injection molding with plastic compound - or by lamination -
- the multilayer decor structure 3 comprises a base layer 7, a further layer on both sides of the base layer 7, specifically a barrier layer 6 and an intermediate layer 5, the barrier layer 6 forming the one outside of the decor structure 3, the second outside is formed by a decorative layer 4
- the decorative layer 4 can consist of a textile material, in particular a synthetic fiber material, for example of polyester fibers, which makes the decorative layer particularly wear-resistant, lightfast and difficult to ignite, but can also consist of leather or an imitation leather is generally carried out in such a way that it represents a surface which is visually appealing to the user and which the user perceives as pleasant.
- the base layer 7 is preferably a nonwoven fabric based on polyester, polyamide, polyacrylate, cellulose or mixed fibers, is also soft, flexible and as light as possible and usually has a thickness of
- the raw material is the uncrosslinked or uncured materials
- the layers 5, 6 consist of the corresponding cross-linked or hardened starting materials.
- an acrylic resin layer or a layer of thermoplastic material are all those which have the desired properties, such as a corresponding temperature resistance, aging resistance and lightfastness
- the barrier layer 6, as its name suggests, has the primary purpose of sealing the base layer 7 and impregnating it superficially, so that in the course of further processing of the decorative structure 3 by injecting or injecting plastic compound, it cannot penetrate into the base layer 7 at the same time the barrier layer has the purpose of complicating the heat transfer - both in the case of back molding or back pressing as well as in further processing by lamination. In any case, the steaming properties of the base layer 7 are thus fully retained.
- the thickness of the barrier layer 6 will vary according to the respective requirements with regard to the influencing of the heat transfer certain decorating acts and also some fleece qualities are more sensitive to temperature, so that in such cases larger layer thicknesses are generally chosen.
- the minimum layer thickness will be 0.05 mm maximum thickness will be 3 mm.
- the preferred range for the layer thickness is between 0.5 and 1 mm
- the intermediate layer 5, which can also be omitted, in which case, as is known from the prior art, the connection of the decorative layer 4 to the base layer 7 can be made directly by flame lamination or by means of an adhesive, also has the purpose of a connecting layer to form between decorative layer 4 and base layer 7
- the intermediate layer 5 can have a steaming effect and additionally form a further barrier against the transfer of heat. Its thickness is therefore also adapted to the respective requirements and, like the thickness of the barrier layer 6, is in one area from 0.05 to 3 mm, in particular 0.5 to 1 mm, can be selected
- the multilayered decorative structure 3 is produced by a lamination process, in that a layer of the selected starting material, which can also be in the form of foam or, in the case of a thermoplastic material, can also be used in powder form, is applied to the base layer 7 on at least one side Coating technologies can be used, the application of a material present in liquid form, for example by brushing or spraying, and in the case of powder Melting can take place. The applied material penetrates superficially into the base layer 7
- the decorative layer 4 in the case of one-sided coating using adhesive, is laminated onto the base layer 7 coated on one or both sides.
- the crosslinking of the latex or the thermoplastic elastomer or the curing of the resin take place, in particular, with the addition of heat 5 a connection with the or the adjacent layers
- the decorative structure 3 is introduced into a corresponding shape and there is a connection of the barrier layer 6 with the plastic mass introduced
- the achievable heat-insulating effect of the barrier layer 6 allows heat-sensitive nonwoven fabrics to be used, for example those which at the same time also have good sound-absorbing properties.
- 3 further components can be integrated into the decorative structure, which so far, because they affect the pressure or temperature conditions during further processing finished interior furnishing stand could not stand, could not be used.
- the base layer 7 can be made in several layers, for example consisting of two layers, and an electrically conductive film can be introduced between these layers To influence or increase the steaming and also the insulating
- the barrier layer 6 can therefore have a layer thickness that differs from the intermediate layer 5, in particular the layer 6 being made thicker. It is also possible to choose different starting materials for the layers 5, 6 in order to support optimization of the properties desired in each case

Tuπnnenverkleidungen, dadurch herzustellen, dass eine Kunststoffmasse durch Hinterspritzen oder Hinterpressen mit einer mehrschichtig aufgebauten Außenverkleidung verbunden wird Bekannte mehrschichtige Außenverkleidungen bestehen beispielsweise aus einer textilen, meist aus Polyester gefertigten Dekorschicht, die mit einer vorzugsweise aus einem Faservlies bestehendenDoor linings to be produced by connecting a plastic compound by injection molding or back pressing to a multilayer outer lining. Known multilayer outer linings consist, for example, of a textile, usually made of polyester, decorative layer, which preferably consists of a nonwoven fabric
Basisschicht mittels eines Klebers durch Aufkaschieren verbunden wird Zwischen der Dekorschicht und der Basisschicht kann eine die Haptik verbessernde Schicht aus PU-Schaumstoff eingebracht sein, die durch Flammkaschieren sowohl mit der Dekorschicht als auch der Basisschicht verbunden wird Wahrend des Hinterspπtz- oder Hinterpressverfahrens dringt die auf- bzw eingebrachte Kunststoffmasse in die Basisschicht ein, wodurch die Verbindung der Außenverkleidung zum Kunststoff hergestellt wird und das Innenausstattungstell entstehtBase layer is connected by means of an adhesive by lamination. Between the decorative layer and the base layer, a haptic-improving layer made of PU foam can be introduced, which is connected to the decorative layer as well as the base layer by flame lamination. or introduced plastic mass into the base layer, which creates the connection between the outer cladding and the plastic and creates the interior trim
Aus der EP-A 0 850 806 ist ein Innenausstattungstell für Fahrzeuge bekannt, welches aus einem starren Tragerformteil und einem mehrschichtigen Dekoraufbau der eingangs genannten Art besteht Das Tragerformteil ist mit einer Faservliesschicht des Dekoraufbaus mittels einer ersten Kleberschicht verbunden
Eine zweite Kleberschicht befindet sich zwischen dem Faservlies und einer Dekorschicht aus Echtleder.From EP-A 0 850 806 an interior fitting position for vehicles is known, which consists of a rigid molded support part and a multi-layer decorative structure of the type mentioned at the outset. The molded support part is connected to a non-woven layer of the decorative structure by means of a first adhesive layer A second layer of adhesive is located between the non-woven fabric and a decorative layer made of real leather.
Bei dem aus der DE-A 197 08 486 bekannten Fahrzeug-Innenausstattungsteil besteht die Dekorschicht ebenfalls aus Leder oder aus einem Lederersatzstoff. Die Dekorschicht ist mit einer Haptik-Zwischenschicht aus einem Polypropylen- oder Polyethylenschaum in Form von Platten- oder Rollenware durch Flammkaschieren oder über gesonderte Schmelzklebefolien verbunden. Die mit der Haptik- Zwischenschicht versehene Dekorschicht wird in ein geeignetes Werkzeug eingelegt und in diesem mit einem Naturfaser-Thermoplastverbund hinterpresst, wodurch das Fahrzeug-Innenausstattungsteil fertig gestellt wird.In the vehicle interior trim part known from DE-A 197 08 486, the decorative layer also consists of leather or a leather substitute. The decorative layer is connected to a haptic intermediate layer made of a polypropylene or polyethylene foam in the form of sheets or rolls by flame lamination or by means of separate hot-melt adhesive films. The decorative layer provided with the haptic intermediate layer is placed in a suitable tool and pressed in with a natural fiber thermoplastic composite, whereby the vehicle interior trim part is completed.
Von besonderer Bedeutung bei Dekorschichten - seien diese aus textilen Materialien oder aus Leder oder Lederersatzstoff hergestellt - sind Optik und Haptik der Oberfläche. Es ist daher wichtig, dass der Dekoraufbau so ausgeführt ist, dass sich seine Oberfläche, die Dekorschicht, durch die Druck- undOf particular importance for decorative layers - be they made of textile materials or leather or leather substitute - are the look and feel of the surface. It is therefore important that the decor structure is designed so that its surface, the decor layer, through the printing and
Temperatureinwirkung während des Weiterverarbeitens - Hinterspritzen, Hinterpressen oder Kaschieren - nicht verändert. Gleichzeitig muss auch eine gute Haftung zum Trägerteil des Innenausstattungsteils gewährleistet sein. Druck- und temperaturempfindlichere Oberflächen bzw. Dekorschichten von Dekoraufbauten können insbesondere beim Hinterspritzen oder Hinterpressen aufgrund der notwendigen Druck- und Temperaturverhältnisse oft nur mit Qualitätseinbußen oder mit erheblichen Nachbearbeitungsaufwand verarbeitet werden.The effect of temperature during further processing - back injection, back pressing or laminating - has not changed. At the same time, good adhesion to the carrier part of the interior trim part must also be guaranteed. Surfaces or decorative layers of decorative structures that are more sensitive to pressure and temperature can often only be processed with inferior quality or with considerable reworking, in particular when back-molding or back-pressing, due to the necessary pressure and temperature conditions.
Dies trifft vor allem auf Dekoraufbauten der oben erwähnten Ausführung zu, wo die Dekorschicht mittels eines Klebers mit der Basisschicht verbunden wird. Dazu kommt, dass hier die an und für sich vorhandenen dämpfenden Eigenschaften der beispielsweise aus einem Faservlies bestehenden Basisschicht beim Hinterspritzen oder Hinterpressen durch den eindringenden Kunststoff stark beeinträchtigt werden. Bei einer Ausführung des Dekoraufbaus mit einer Zwischenschicht aus einem Schaumstoff, beispielsweise aus PU-Schaumstoff, können druck- und temperaturempfindlichere Dekorschichten besser verarbeitet werden. Das zum Verbinden der Schaumstoffschicht eingesetzte Flammkaschieren ist jedoch durch
das Austreten von schädlichen Dampfen aus dem Schaumstoff problematisch und wird in letzter Zeit eher gemiedenThis applies in particular to decorative structures of the type mentioned above, where the decorative layer is connected to the base layer by means of an adhesive. In addition, the inherent damping properties of the base layer, which consists, for example, of a nonwoven fabric, are greatly impaired by the penetrating plastic during the back injection or back pressing. If the decorative structure is designed with an intermediate layer made of a foam, for example made of PU foam, pressure and temperature-sensitive decorative layers can be processed better. The flame lamination used to connect the foam layer is however through the escape of harmful vapors from the foam is problematic and has been avoided recently
Die Erfindung hat sich daher zur Aufgabe gestellt, bei einem mehrschichtigen Dekoraufbau der eingangs genannten Art unter Verzicht auf den Einsatz von Schaumstoffschichten die dampfende Wirkung zu verbessern und den Aufbau so zu gestalten, dass weitgehend alle, auch druck- und temperaturempfindhchere Dekorschichten mittels der mit thermischen Belastungen verbundenen und unter Pressdruck stattfindenden Technologien zur Herstellung von Innenausstattungstellen ohne Quahtatseinbußen einsetzbar sind, und dass eine gute Haftung zum Tragerteil sichergestellt werden kann Das Fahrzeug-The invention has therefore set itself the task of improving the steaming effect in a multi-layer decorative structure of the type mentioned without the use of foam layers and to design the structure so that largely all, including pressure and temperature sensitive decorative layers by means of thermal Technologies that are subject to stress and take place under pressure and can be used to produce interior fittings without sacrificing quality, and that good adhesion to the carrier part can be ensured.
Innenausstattungsteil soll daher in hoher Qualität und insbesondere auch mit Dekoraufbauten mit druck- und temperaturempfindhcheren Dekorschichten herstellbar seinInterior parts should therefore be able to be produced in high quality and in particular also with decorative structures with pressure and temperature-sensitive decorative layers
Gelost wird die gestellte Aufgabe erfindungsgemaß dadurch, dass auf dieThe object is achieved according to the invention in that the
Außenseite der Basisschicht eine die Basisschicht versiegelnde und oberflächlich imprägnierende Sperrschicht aus einem verformbaren elastischen Material aufgebracht istOn the outside of the base layer, a barrier layer of a deformable elastic material that seals the base layer and is impregnated on the surface is applied
Die aus einem elastischen Material bestehende Sperrschicht besitzt eine Anzahl sehr vorteilhafter Eigenschaften Von besonderer Bedeutung sind ihre Funktion als Versiegelungsschicht sowie ferner ihre dampfenden und isolierenden Eigenschaften Die Sperrschicht hat eine besondere Bedeutung, wenn der Dekoraufbau bei der Herstellung eines Fahrzeug-Innenausstattungsteils mit dem Tragerteil verbunden wird Bei der Anwendung eines Direktverfahrens -The barrier layer, which is made of an elastic material, has a number of very advantageous properties. Its function as a sealing layer and its steaming and insulating properties are of particular importance. The barrier layer is of particular importance if the decorative structure is connected to the carrier part during the manufacture of a vehicle interior trim part When using a direct procedure -
Hinterspritzen oder Hinterpressen - geht die Schicht aus elastischem Material eine Verbindung mit der Kunststoffmasse ein, wobei kein Eindringen derselben in die Basisschicht mehr erfolgt Das heißt, dass die dampfenden Eigenschaften der Basisschicht voll erhalten bleiben können, so dass diese die Funktion der die erwünschte Haptik gewährleistenden Schicht übernehmen kann Darüber hinaus erschwert die Sperrschicht die Übertragung von Warme und nimmt Pressdruck auf, so dass bei einem erfindungsgemaß ausgeführten Dekoraufbau auch Dekorschichten, die aus einem druck- und warmeempfindlicheren Material
bestehen, eingesetzt werden können, ohne dass Qualitatseinbußen zu erwartenInjection molding or injection molding - the layer of elastic material forms a connection with the plastic mass, whereby it no longer penetrates into the base layer.This means that the steaming properties of the base layer can be fully retained, so that they ensure the function of the desired feel In addition, the barrier layer complicates the transfer of heat and absorbs pressure, so that with a decorative structure according to the invention also decorative layers made of a material that is more sensitive to pressure and heat exist, can be used without expected loss of quality
Bei einer bevorzugten Ausfuhrungsform der Erfindung besteht auch die zwischen der Basisschicht und der Dekorschicht angeordnete Zwischenschicht aus einem verformbaren und elastischen Material (Anspruch 2) Dadurch kann dieIn a preferred embodiment of the invention, the intermediate layer arranged between the base layer and the decorative layer also consists of a deformable and elastic material (claim 2)
Zwischenschicht neben ihrer Funktion als Verbindungsschicht auch warmeisoherend und druckaufnehmend und somit dampfend wirkenIntermediate layer, in addition to its function as a connecting layer, also has a heat-insulating and pressure-absorbing effect and thus has a steaming effect
Als Ausgangsmatenal für das verformbare elastische Material kommen erfindungsgemaß insbesondere Latex, Acrylharz oder ein thermoplastisches Elastomer in Frage (Anspruch 3) Gerade bei diesen Materialien kann durch die Mischungszusammensetzung sichergestellt werden, dass sie über die erforderlichen oder erwünschten Eigenschaften hinsichtlich Temperaturbeständigkeit, Alterungsbestandigkeit, Lichtechtheit etc verfugen könnenAccording to the invention, latex, acrylic resin or a thermoplastic elastomer are particularly suitable as the starting material for the deformable elastic material (claim 3). With these materials in particular, the mixture composition can ensure that they have the required or desired properties with regard to temperature resistance, aging resistance, lightfastness, etc. can
Die Verbindungs- und Versiegelungsfunktion sowie die elastischen Eigenschaften des jeweiligen Materials werden dadurch sichergestellt, dass das entsprechende Ausgangsmatenal in unvemetzter bzw ungehärteter Form eingesetzt wird, wobei jedoch im fertigen Dekoraufbau die Sperrschicht und ggf die Zwischenschicht aus dem vernetzten bzw geharteten Material bestehen (Anspruch 4)The connection and sealing function as well as the elastic properties of the respective material are ensured by the fact that the corresponding starting material is used in uncured or uncured form, however in the finished decor structure the barrier layer and possibly the intermediate layer consist of the cross-linked or hardened material (claim 4)
Bei einer weiteren bevorzugten Ausfuhrungsform der Erfindung können für die Sperrschicht und die Zwischenschicht unterschiedliche Ausgangsmatenalien eingesetzt werden (Anspruch 5) Damit kann Einfluss auf bevorzugte oder erwünschte Eigenschaften oder Funktionen der Schichten, beispielsweise was ihre elastischen und isolierenden Eigenschaften betrifft, genommen werdenIn a further preferred embodiment of the invention, different starting materials can be used for the barrier layer and the intermediate layer (claim 5). This can have an influence on preferred or desired properties or functions of the layers, for example as regards their elastic and insulating properties
Bei einer weiteren erfindungsgemaßen Ausfuhrungsvariante kann vorgesehen werden, dass die Sperrschicht eine Schichtstarke aufweist, die von jener der Zwischenschicht abweicht (Anspruch 6) Auch diese Maßnahme gestattet es, auf erwünschte oder geforderte Eigenschaften entsprechend Einfluss zu nehmen
Dabei wird die Ausfuhrung insbesondere so getroffen, dass die Zwischenschicht eine größere Schichtstarke aufweist als die Sperrschicht (Anspruch7) Damit kann auch die Zwischenschicht, zusätzlich zur Basisschicht, auf die Haptik der Dekorschicht Einfluss nehmenIn a further embodiment variant according to the invention, it can be provided that the barrier layer has a layer thickness which differs from that of the intermediate layer (claim 6). This measure also allows the desired or required properties to be influenced accordingly In this case, the design is in particular such that the intermediate layer has a greater layer thickness than the barrier layer (claim 7). Thus, in addition to the base layer, the intermediate layer can also influence the feel of the decorative layer
Bei einer weiteren Ausfuhrungsform der Erfindung kann die Basisschicht mehrlagig, insbesondere zweilagig ausgeführt werden (Anspruch 8) Damit ist die Möglichkeit eröffnet, zwischen diesen Lagen zusatzliche Einbauten unterzubringen Solche Einbauten können beispielsweise elektrisch leitende Folien sein (Anspruch 9) Die Fähigkeit der Sperrschicht, Druck aufzunehmen und die Übertragung von Warme zu behindern, macht es möglich, für den Benutzer vorteilhafte, zusatzliche Einbauten im Dekoraufbau unterzubringen, was bislang, insbesondere wegen der Hitzeempfindlichkeit der in Frage kommenden Materialien, nicht möglich warIn a further embodiment of the invention, the base layer can be designed in multiple layers, in particular in two layers (claim 8). This opens up the possibility of accommodating additional internals between these layers. Such internals can be, for example, electrically conductive foils (claim 9). The ability of the barrier layer to absorb pressure and hindering the transfer of heat makes it possible for the user to accommodate additional fittings which are advantageous for the user in the decorative structure, which has not been possible hitherto, in particular because of the heat sensitivity of the materials in question
Die gemäß der gegenständlichen Erfindung vorgesehene Sperrschicht und auch die gegebenenfalls erfindungsgemaß vorgesehene Zwischenschicht werden jeweils in einer Schichtstarke von 0,05 bis 3 mm, insbesondere von 0,5 bis 1 mm, ausgeführt (Anspruch 10) Eine Mindestschichtstarke ist erforderlich, um die Verbindungs- und Versiegelungsfunktion sicherzustellen Eine gewisse Begrenzung der Schichtstarke nach oben zu ist gunstig, um das Gewicht des Dekoraufbaus nicht unnötig zu erhohen Für die erwünschten isolierenden und dampfenden Eigenschaften sind Schichtstarken von bis zu 3 mm im Allgemeinen durchaus ausreichendThe barrier layer provided according to the present invention and also the intermediate layer optionally provided according to the invention are each made in a layer thickness of 0.05 to 3 mm, in particular 0.5 to 1 mm. A minimum layer thickness is required in order to and ensure the sealing function A certain upper limit of the layer thickness is favorable in order not to unnecessarily increase the weight of the decorative structure. Layer thicknesses of up to 3 mm are generally sufficient for the desired insulating and steaming properties

Dabei kann dieses Fahrzeug-Innenausstattungsteil nach einem Direktverfahren, durch Hinterspritzen oder Hinterpressen, hergestellt sein (Anspruch 12) Es ist aber auch eine Herstellung durch Kaschieren möglich (Anspruch 13) Bei beiden Herstellverfahren ist gewährleistet, dass bei den auftretenden Temperaturen und bei den herrschenden Druckverhaltnissen auch druck- und temperaturempfindliche Dekorschichten ihre Qualität behaltenThe subject invention also relates to a vehicle interior trim part comprising a shaping support part and a multi-layer decorative structure with a base layer and a decorative layer. A vehicle interior trim part designed according to the invention is provided with a decorative structure according to at least one of claims 1 to 10 (claim 11) The advantageous properties of the decorative structure mentioned above are also present in the vehicle interior trim part according to the invention, so that it is possible to provide a high-quality interior trim panel, the decorative layer of which can also consist of a pressure- or heat-sensitive material This vehicle interior trim part can be produced by a direct process, by back injection or back pressing (claim 12). However, production by lamination is also possible (claim 13). With both production processes, it is ensured that at the temperatures that occur and under the prevailing pressure conditions Even decorative layers sensitive to pressure and temperature retain their quality
Erfindungsgemaß ausgeführte Fahrzeug-Innenausstattungsteile sind insbesondere Turmnenverkleidungen, Saulenverkleidungen oder Gepackraumauskleidungen (Anspruch 14) Gerade bei diesen Verkleidungen oder Auskleidungen werden besonders hohe Ansprüche an den Dekoraufbau, insbesondere was die Qualltat des Materials der Dekorschicht betrifft, gestellt Mit der gegenständlichen Erfindung können diesen Ansprüchen gerecht werdende Verkleidungen oder Auskleidungen zur Verfugung gestellt werdenVehicle interior fittings designed according to the invention are, in particular, tower cladding, pillar cladding or luggage compartment linings (claim 14). Particularly with these claddings or linings, particularly high demands are made on the decor structure, in particular as regards the quality of the material of the decorative layer, with the present invention can meet these claims Panels or linings are provided

Ein erfindungsgemaß ausgeführtes Fahrzeug-Innenausstattungsteil 1 kann beispielsweise eine Tuπnnenverkleidung, eine Saulenverkleidung oder eine Gepackraumauskleidung sein Wie Fig 2 zeigt, besteht das Fahrzeug- Innenausstattungstell 1 aus einem seinen tragenden Bestandteil bildenden und formgebenden Tragerteil 2, insbesondere aus Kunststoff, und einem mehrschichtigen Dekoraufbau 3 Unter Heranziehen des mehrschichtigen Dekoraufbaus 3 kann nun das Innenaustattungsteil in einem Direktverfahren -

As FIG. 2 shows, the vehicle interior trim 1 consists of a support part 2, in particular made of plastic, which forms and forms its load-bearing component, and a multilayer decorative structure 3 sub Using the multilayer decorative structure 3, the interior part can now be used in a direct process. Injection molding or injection molding with plastic compound - or by lamination -

Der mehrschichtige Dekoraufbau 3 umfasst in der in den beiden Zeichnungsfiguren dargestellten Ausfuhrungsform eine Basisschicht 7, beidseitig der Basisschicht 7 je eine weitere Schicht, und zwar eine Sperrschicht 6 und eine Zwischenschicht 5, wobei die Sperrschicht 6 die eine Außenseite des Dekoraufbaus 3 bildet Die zweite Außenseite wird von einer Dekorschicht 4 gebildetIn the embodiment shown in the two drawing figures, the multilayer decor structure 3 comprises a base layer 7, a further layer on both sides of the base layer 7, specifically a barrier layer 6 and an intermediate layer 5, the barrier layer 6 forming the one outside of the decor structure 3, the second outside is formed by a decorative layer 4
Die Dekorschicht 4, deren Design wahlbar ist, kann aus einem textilen Material, insbesondere einem synthetischen Fasermateπal, beispielsweise aus Polyesterfasern bestehen, wodurch die Dekorschicht besonders verschleißfest, lichtecht und schwer entzündbar ausgeführt ist, kann aber auch aus Leder bzw einem Lederimitat bestehen Die Dekorschicht 4 wird im Allgemeinen so ausgeführt, dass sie eine den Benutzer optisch ansprechende und von diesem als angenehm empfundene Oberflache darstellt Die Basisschicht 7 ist vorzugsweise ein Faservlies auf der Basis von Polyester, Polyamid, Polyacrylat, Zellstoff oder Mischfasern, ist ferner weich, flexibel und möglichst leicht und besitzt üblicherweise eine Dicke von
The decorative layer 4, the design of which can be selected, can consist of a textile material, in particular a synthetic fiber material, for example of polyester fibers, which makes the decorative layer particularly wear-resistant, lightfast and difficult to ignite, but can also consist of leather or an imitation leather is generally carried out in such a way that it represents a surface which is visually appealing to the user and which the user perceives as pleasant. The base layer 7 is preferably a nonwoven fabric based on polyester, polyamide, polyacrylate, cellulose or mixed fibers, is also soft, flexible and as light as possible and usually has a thickness of
Die beidseitig der Basisschicht 7 angeordneten weiteren Schichten, Zwischenschicht 5 und Sperrschicht 6, bestehen aus einem dauerelastischen verformbaren Material, wobei im Rahmen der gegenständlichen Erfindung als Material synthetischer Latex, Acrylharz oder ein thermoplastisches Elastomer in Frage kommen Das Ausgangsmatenal bilden dabei die unvemetzten bzw ungehärteten Materialien, wobei im fertigen Dekoraufbau die Schichten 5, 6 aus den entsprechenden vernetzten bzw ausgeharteten Ausgangsmateπalien bestehen Als Ausgangsmateπalien für eine Latexschicht, eine Acrylharzschicht oder eine Schicht aus thermoplastischen Material kommen all jene in Frage, die über die erwünschten Eigenschaften, wie eine entsprechende Temperaturbeständigkeit, Alterungsbestandigkeit und Lichtechtheit, verfugen
Die Sperrschicht 6 hat, wie bereits ihre Bezeichnung aussagt, vorrangig den Zweck, die Basisschicht 7 zu versiegeln und oberflächlich zu imprägnieren, so dass im Zuge einer Weiterverarbeitung des Dekoraufbaus 3 durch Hinterspritzen oder Hinterpressen von Kunststoffmasse diese nicht in die Basisschicht 7 eindringen kann Zugleich hat die Sperrschicht den Zweck, den Wärmeübergang - sowohl beim Hinterspritzen oder Hinterpressen als auch bei einer Weiterverarbeitung durch Kaschieren - zu erschweren In jedem Fall bleiben somit die dampfenden Eigenschaften der Basisschicht 7 voll erhalten Die Dicke der Sperrschicht 6 wird sich nach den jeweiligen Anforderungen bezüglich der Beeinflussung des Wärmeüberganges richten Bestimmte Dekorqualltaten und auch manche Vliesqualltaten sind eher temperaturempfindlich, so dass für solche Falle im Allgemeinen größere Schichtdicken gewählt werden Um überhaupt eine Versiegelungswirkung zu erzielen, wird die Mindestschichtdicke 0,05 mm betragen, die maximale Dicke wird bei 3 mm liegen Der bevorzugte Bereich für die Schichtdicke betragt zwischen 0,5 und 1 mmThe further layers, intermediate layer 5 and barrier layer 6, arranged on both sides of the base layer 7, consist of a permanently elastic deformable material, synthetic latex, acrylic resin or a thermoplastic elastomer being suitable as material in the context of the present invention.The raw material is the uncrosslinked or uncured materials , In the finished decorative structure, the layers 5, 6 consist of the corresponding cross-linked or hardened starting materials. Starting materials for a latex layer, an acrylic resin layer or a layer of thermoplastic material are all those which have the desired properties, such as a corresponding temperature resistance, aging resistance and lightfastness The barrier layer 6, as its name suggests, has the primary purpose of sealing the base layer 7 and impregnating it superficially, so that in the course of further processing of the decorative structure 3 by injecting or injecting plastic compound, it cannot penetrate into the base layer 7 at the same time the barrier layer has the purpose of complicating the heat transfer - both in the case of back molding or back pressing as well as in further processing by lamination. In any case, the steaming properties of the base layer 7 are thus fully retained. The thickness of the barrier layer 6 will vary according to the respective requirements with regard to the influencing of the heat transfer certain decorating acts and also some fleece qualities are more sensitive to temperature, so that in such cases larger layer thicknesses are generally chosen. In order to achieve a sealing effect at all, the minimum layer thickness will be 0.05 mm maximum thickness will be 3 mm. The preferred range for the layer thickness is between 0.5 and 1 mm
Die Zwischenschicht 5, die auch weggelassen werden kann, wobei in diesem Fall, wie es aus dem Stand der Technik bekannt ist, die Verbindung der Dekorschicht 4 zur Basisschicht 7 direkt durch Flammkaschieren oder mittels eines Kleber erfolgen kann, hat auch den Zweck, eine Verbindungsschicht zwischen Dekorschicht 4 und Basisschicht 7 zu bilden Darüber hinaus kann die Zwischenschicht 5 dampfend wirken und zusätzlich eine weitere Barriere gegen die Übertragung von Warme bilden Ihre Dicke wird daher ebenfalls an die jeweiligen Anforderungen angepasst und wird, wie die Dicke der Sperrschicht 6, in einem Bereich von 0,05 bis 3 mm, insbesondere 0,5 bis 1 mm, gewählt werdenThe intermediate layer 5, which can also be omitted, in which case, as is known from the prior art, the connection of the decorative layer 4 to the base layer 7 can be made directly by flame lamination or by means of an adhesive, also has the purpose of a connecting layer to form between decorative layer 4 and base layer 7 In addition, the intermediate layer 5 can have a steaming effect and additionally form a further barrier against the transfer of heat. Its thickness is therefore also adapted to the respective requirements and, like the thickness of the barrier layer 6, is in one area from 0.05 to 3 mm, in particular 0.5 to 1 mm, can be selected
Der mehrschichtige Dekoraufbau 3 wird nach einem Kaschierverfahren hergestellt, indem auf die Basisschicht 7 zumindest einseitig eine Schicht aus dem gewählten Ausgangmaterial, welches auch als Schaum vorliegen kann oder im Fall eines thermoplastischen Materials auch in Pulverform eingesetzt werden kann, aufgebracht wird Zum Aufbringen sind die gangigen Beschichtungstechnologien einsetzbar, wobei das Aufbringen eines in flussiger Form vorliegenden Materials beispielsweise durch Aufstreichen oder Aufsprühen und bei Pulver ein
Aufschmelzen erfolgen kann Das aufgebrachte Material dringt dabei oberflächlich in die Basisschicht 7 einThe multilayered decorative structure 3 is produced by a lamination process, in that a layer of the selected starting material, which can also be in the form of foam or, in the case of a thermoplastic material, can also be used in powder form, is applied to the base layer 7 on at least one side Coating technologies can be used, the application of a material present in liquid form, for example by brushing or spraying, and in the case of powder Melting can take place. The applied material penetrates superficially into the base layer 7
Auf die ein- oder beidseitig beschichtete Basisschicht 7 wird die Dekorschicht 4, bei einseitiger Beschichtung unter Verwendung von Kleber, aufkaschiert Die Vernetzung des Latex bzw des thermoplastischen Elasomers oder die Aushärtung des Harzes erfolgen insbesondere unter Wärmezufuhr Dabei geht die Sperrschicht 6 und die gegebenenfalls aufgebrachte Zwischenschicht 5 mit der bzw den benachbarten Schichten eine Verbindung einThe decorative layer 4, in the case of one-sided coating using adhesive, is laminated onto the base layer 7 coated on one or both sides. The crosslinking of the latex or the thermoplastic elastomer or the curing of the resin take place, in particular, with the addition of heat 5 a connection with the or the adjacent layers
Bei der Weiterverarbeitung zur Herstellung des betreffenden Fahrzeug-During further processing to manufacture the vehicle in question
Innenausstattungsteils 1 durch Hinterspritzen oder durch Hinterpressen wird der Dekoraufbau 3 in eine entsprechende Form eingebracht und es erfolgt eine Verbindung der Sperrschicht 6 mit der eingebrachten Kunststoff masseInterior trim part 1 by back molding or by back pressing, the decorative structure 3 is introduced into a corresponding shape and there is a connection of the barrier layer 6 with the plastic mass introduced
Im Falle einer Weiterverarbeitung durch Kaschieren erfolgt eine Verbindung mit dem Tragerteil 2 über einen KleberIn the case of further processing by lamination, there is a connection to the carrier part 2 via an adhesive
Da beim Hinterspritzen oder Hinterpressen Kunststoff nicht mehr in die Basisschicht 7 eindringen kann, ist es möglich, bei Anwendung dieser Technologien die Schicht 7 mit geringerer Dicke auszufuhren als beim Stand der Technik und damit eine Gewichtsreduzierung zu erzielenSince plastic can no longer penetrate into the base layer 7 during back injection or back pressing, it is possible, when using these technologies, to carry out layer 7 with a smaller thickness than in the prior art and thus to achieve a weight reduction
Darüber hinaus gestattet die erzielbare warmeisoherende Wirkung der Sperrschicht 6 warmeempfindhchere Vliesquahtaten einzusetzen, beispielsweise solche, die gleichzeitig auch gute schallabsorbierende Eigenschaften haben Darüber hinaus können in den Dekoraufbau 3 weitere Bauteile integriert werden, die bislang, da sie den Druck- oder Temperaturverhaltnissen bei der Weiterverarbeitung zum fertigen Innenausstattungstell nicht standhielten, nicht eingesetzt werden konnten So kann beispielsweise die Basisschicht 7 mehrlagig, etwa aus zwei Lagen bestehend ausgeführt werden und zwischen diese Schichten eine elektrisch leitende Folie eingebracht werden
Zur Beeinflussung bzw zur Erhöhung der dampfenden und auch der isolierendenIn addition, the achievable heat-insulating effect of the barrier layer 6 allows heat-sensitive nonwoven fabrics to be used, for example those which at the same time also have good sound-absorbing properties. In addition, 3 further components can be integrated into the decorative structure, which so far, because they affect the pressure or temperature conditions during further processing finished interior furnishing stand could not stand, could not be used. For example, the base layer 7 can be made in several layers, for example consisting of two layers, and an electrically conductive film can be introduced between these layers To influence or increase the steaming and also the insulating
Eigenschaften wird vor allem die Dicke der Sperrschicht 6 entsprechend eingestellt werden. Es kann daher die Sperrschicht 6 eine von der Zwischenschicht 5 abweichende Schichtstarke aufweisen, wobei insbesondere die Schicht 6 starker ausgeführt wird Dabei ist es auch möglich, für die Schichten 5, 6 unterschiedliche Ausgangsmatenalien zu wählen, um eine Optimierung der jeweils erwünschten Eigenschaften zu unterstutzen
Properties, especially the thickness of the barrier layer 6 will be adjusted accordingly. The barrier layer 6 can therefore have a layer thickness that differs from the intermediate layer 5, in particular the layer 6 being made thicker. It is also possible to choose different starting materials for the layers 5, 6 in order to support optimization of the properties desired in each case
