Description

Die vorstehende Erfindung betrifft ein Polsterteil, sowie ein Verfahren zu dessen Herstellung.The above invention relates to a cushion part, as well a process for its manufacture.

Im Folgenden wird auf ein Polsterteil aus synthetischem Material, z.B. aus einem Polyuretanwerkstoff Bezug genommen.Below is a synthetic upholstery part Material, e.g. made of a polyurethane material cover taken.

Die vorstehende Erfindung betrifft ein Polsterteil für die Herstellung von Matratzen, welche sehr bequem und widerstandsfähig sind und an denen die Verbraucher Gefallen gefunden haben.The above invention relates to a cushion part for the Manufacture of mattresses that are very comfortable and are resilient and to which consumers like have found.

Es ist naheliegend, dass das im Nachfolgenden beschriebene Bauteil sowie das dazugehörige Verfahren auch für die Herstellung von einer Polsterung für Sitzflächen und / oder Rückenlehnen von Stühlen oder Sofas, Kissen oder Polstern oder sanitären Erzeugnissen, wie z.B. Sitzpolstern für Kinderwagen, Nierenstützen in besonderer Ausführungsform einsetzbar sind.It is obvious that the following described Component and the associated process also for the Manufacture of upholstery for seats and / or Backrests of chairs or sofas, pillows or upholstery or sanitary products such as Seat cushions for Strollers, kidney supports in a special embodiment can be used.

Die herkömmlichen aus Kunststoff bestehenden Polsterungen weisen üblicherweise eine Schicht bestehend aus elastischem Material in Kombination mit einer Schicht aus viskoelastischen Material auf.The traditional plastic upholstery usually have a layer consisting of elastic Material in combination with a layer of viscoelastic material.

Die Verwendung von viskoelastischem Material führt zu einem erheblichen Konfort, da es in gewisser Weise Formgedächtnismerkmale aufweist und eine Verformung bei Aufliegen des Körpers auf der Matratze unter geringem Einfluß auf den Körper des Benutzers aufweist und nach Verlassen der Matratze durch den Benutzer in seine ursprüngliche Form zurückkehrt. Ferner sind viskoelastische Materialen wärmeempfindlich und verformen sich auch bei Einwirken der Körperwärme des Benutzers, Tatsache, die zu einem weiteren Komfort für den Benutzer führt.The use of viscoelastic material leads to a considerable comfort as it is in some ways Has shape memory features and a deformation The body lies on the mattress with little Has influence on the body of the user and after Leaving the mattress by the user in his original form returns. They are also viscoelastic Materials are sensitive to heat and also deform Exposure to the user's body heat, fact that too leads to a further convenience for the user.

Besonders weisen die herkömmlichen Polsterungen in Draufsicht zwei Schichten mit gleichen Abmessungen auf und diese Schichten sind aus elastischem Material und viskoelastischem Material gebildet, wobei die beiden Schichten durch eine weitere Kleberschicht miteinander verbunden sind.In particular, the conventional upholstery in Top view of two layers with the same dimensions on and these layers are made of elastic material and viscoelastic material formed, the two Layers together with another layer of adhesive are connected.

Die herkömmlichen Polsterungen weisen zahlreiche Nachteile auf, die hauptsächlich darin zu sehen sind, dass die Klebeschicht im Laufe der Zeit einen Alterungsprozess erfährt und zu einer Verhärtung des Klebers führt sowie zum Lösen der miteinander verklebten Schichten.The conventional upholstery has numerous disadvantages that can be seen mainly in the fact that the Adhesive layer over time an aging process experiences and leads to hardening of the adhesive and to Detach the layers glued together.

Desweiteren konnte festgestellt werden, dass bei den bekannten Polsterungen Schäden aufgrund eines mangelhaften Klebers oder aufgrund einer nicht sachgerechten Verklebung auftreten können.Furthermore, it was found that the known upholstery damage due to poor Glue or due to improper gluing may occur.

Ferner, da die beiden Schichten der Polsterungen miteinander verklebt sind, ist es unumgänglich, dass die miteinander verbundenen Flächen der beiden Schichten als ebenes Bauteil auszuführen sind oder unter Verwendung von Krümmungen mit sehr großem Radius, um zu gewährleisten, dass die zu verbindenden Flächen stets flächig miteinander verbunden bleiben. Es würden erhebliche Schwierigkeiten auftreten, die zu einer Verteuerung des Fertigungsprozesses führen würden, wenn zwei Flächen von Materialschichten miteinander zu verbinden wären, die nicht im Wesentlichen ebenen Verlauf hätten oder über genau zueinander passende Verbindungsprofile zu verbinden wären.Furthermore, since the two layers of upholstery are glued together, it is imperative that the interconnected areas of the two layers as flat component to be executed or using Very large radius bends to ensure that the surfaces to be connected are always flat with one another stay connected. There would be significant difficulties occur that lead to an increase in the cost of the manufacturing process would result if two faces of layers of material would be connected to each other that are not essentially have a flat course or over exactly matching one another Connection profiles would be connected.

Aufgabe der vorstehenden Erfindung ist es die eingangs genannten technischen Nachteile des Standes der Technik zu vermeiden.The object of the above invention is the above mentioned technical disadvantages of the prior art avoid.

Besonders ist es Aufgabe der Erfindung, ein Polsterteil zu schaffen, bei dem die Gefahr, dass sich zwei miteinander verbundene Schichten voneinander lösen, sehr gering ist. Eine weitere Aufgabe der Erfindung besteht darin, ein Polsterteil zu schaffen, das bereits als neues Fertigteil als Ausschuss zu bewerten ist, da die Klebevorgänge nicht fachgerecht durchgeführt wurden.It is a particular object of the invention to provide a cushion part create the danger of two being together detach connected layers from each other is very low. Another object of the invention is to provide a To create an upholstered part that is already a new finished part is to be rated as a scrap, since the gluing process is not were carried out professionally.

Dies ist besonders wichtig, da in bekannter Weise Klebevorgänge von Bauteilen aus Kunststoff größte Fachkenntnis voraussetzen.This is particularly important because in a known manner Gluing processes of plastic components largest Require expertise.

Ferner besteht bei Klebeverbindungen die Gefahr, dass Allergien aufgrund der eingesetzten chemischen Lösungsmittel auftreten könnten und Abneigungen gegenüber der Verwendung herkömmlicher Matratzen mit Klebeverbindungen bestehen könnten.There is also a risk of adhesive connections that Allergies due to the chemical used Solvents could occur and dislike using conventional mattresses Adhesive connections could exist.

Eine weitere Aufgabe der Erfindung ist darin zu sehen ein Polsterteil zu schaffen, bei dem die gegenseitig miteinander verbundenen Flächen der elastischen Schicht und der viskoelastischen Schicht besonders aufwendige Formgestaltung aufweisen, z.B. unter Vorsehung von zahlreichen, vorspringenden Teilen und / oder Ausnehmungen mit Hinterschneidung.Another object of the invention is to be seen therein To create upholstered part in which the mutual interconnected surfaces of the elastic layer and the viscoelastic layer is particularly complex Have a shape, e.g. provided of numerous protruding parts and / or recesses with undercut.

Auf diese Weise besteht bei Vorsehung sehr aufwendiger Formgebung für die zu verbindenden Schichten die Gefahr, dass die fertiggestellte Matratze weniger tragende Flächen aufweist, z.B. in Übereinstimmung mit den Schultern, den Fußgelenken oder des Nierenbreiches des Benutzers.In this way, the providence is very complex Shaping for the layers to be connected the risk that the finished mattress has less load-bearing surfaces e.g. in accordance with the shoulders Ankles or the kidney area of the user.

Die vorgenannten Aufgaben werden mittels eines Polsterteiles gelöst, das aus einer elastischen Schicht und einer viskoelastischen Schicht besteht und sich dadurch kennzeichnet, dass die elastische Schicht und die viskoelastische Schicht direkt in Übereinstimmung mit Wandteilen verbunden sind.The aforementioned tasks are carried out by means of a Upholstered part released, which consists of an elastic layer and consists of a viscoelastic layer and thereby indicates that the elastic layer and the viscoelastic layer directly in accordance with Wall parts are connected.

Mit besonderem Vorteil weisen die inneren Wandteile der elastischen Schicht und der viskoelastischen Schicht einen geformten Verlauf auf.The inner wall parts of the elastic layer and the viscoelastic layer shaped course.

Es ist ferner vorteilhaft, dass das Polsterteil zwei oder mehrere Teilfächen mit unterschiedlicher Formgebung aufweist, um somit diesen Teilflächen unterschiedliche Tragfähigkeit zu verleihen.It is also advantageous that the cushion part two or several compartments with different shapes has, so that these sub-areas different To give load capacity.

In vorteilhafter Weise weist die viskoelastische Schicht Randbereiche auf, die zumindestens teilweise die Seitenbereiche der elastischen Schicht oder umgekehrt abdecken.The viscoelastic layer advantageously has Marginal areas that are at least partially the Side areas of the elastic layer or vice versa cover.

In einer besonderen Ausführungsform bestehen die elastische Schicht und die viskoelastische Schicht im Wesentlichen aus einem Polyuretanwerkstoff und das Polsterteil wird für die Schaffung einer Matratze herangezogen.In a special embodiment, the elastic Layer and the viscoelastic layer essentially a polyurethane material and the upholstery part is for the Creation of a mattress.

Die vorstehende Erfindung bezieht sich ferner auf ein Verfahren zur Herstellung eines Polsterteiles, welches dadurch gekennzeichnet ist, dass eine Schicht bestehend aus elastischem Material oder eine Schicht bestehend aus viskoelastischem Material im Inneren einer Form angeordnet wird und das Innere dieser Form mit viskoelastischem Material oder elastischem Material ausgeschäumt wird, um ein Polsterteil zu schaffen, das aus einer elastischen und einer viskoelastischen Schicht besteht, und die Schichten direkt miteinander verbunden sind.The above invention further relates to Process for producing an upholstered part, which is characterized in that a layer consisting of elastic material or a layer consisting of viscoelastic material arranged inside a mold and the inside of this shape with viscoelastic Material or elastic material is foamed to to create an upholstered part that consists of an elastic and consists of a viscoelastic layer, and the layers are directly connected.

In der Praxis ist es möglich, das Polsterteil dadurch herzustellen, indem in die Form das elastische Material eingebracht wird und ein Ausschäumen mittels eines viskoelastischen Materials erfolgt oder umgekehrt, d.h., indem in die Form viskoelastisches Material eingebracht wird und der Ausschäumvorgang mittels elastischem Material vervollständigt wird.In practice it is possible to use the padding part manufacture by inserting the elastic material into the mold is introduced and foaming by means of a viscoelastic material or vice versa, i.e. by introducing viscoelastic material into the mold and the foaming process using elastic material is completed.

In vorteilhafter Weise wird das viskoelastische Material an einer Frontseite einer Wand oder in Übereinstimmung mit den Seitenrändern der elastischen Schicht eingespritzt.The viscoelastic material is advantageously applied a front of a wall or in accordance with the Injected side edges of the elastic layer.

Nach einer weiteren Ausführungsform wird das viskoelastische Material nicht nur an der Oberseite und seitlich in die Form eingebracht, sondern auch an der Unterseite der elastischen Schicht oder umgekehrt.According to a further embodiment, the viscoelastic material not only on the top and introduced laterally into the mold, but also on the Underside of the elastic layer or vice versa.

Das somit hergestellte Polsterteil sowie das dazu erforderliche Verfahren sind besonders wirtschaftlich, besonders im Vergleich mit Polsterteilen sowie deren Herstellungsverfahren, die aus dem Stand der Technik bekannt sind und ferner tritt eine verminderte Ausschußquote auf.The upholstered part manufactured in this way as well as that required procedures are particularly economical, especially when compared to upholstery parts and their Manufacturing process based on the state of the art are known and further occurs a diminished Reject rate on.

    Das Posterteil 1 weist eine elastische Schicht 2 auf sowie eine viskoelastische Schicht 3; die Schichten 2,3 sind miteinander in Übereinstimmung mit sich gegenüberliegenden inneren Flächen 4 verbunden.The poster part 1 has an elastic layer 2 and a viscoelastic layer 3; the layers are 2,3 with each other in accordance with opposite inner surfaces 4 connected.

    In vorteilhafter Weise sind die elastische Schicht 2 sowie die viskoelastische Schicht 3 direkt miteinander verbunden, ohne für diesen Verbindungsvorgang einen Kleber einzusetzen.Advantageously, the elastic layer 2 and the viscoelastic layer 3 is directly connected to one another, without an adhesive for this connection process use.

    Wie der Figur 3 zu entnehmen ist, weisen die Flächen der elastischen Schicht 2 sowie der viskoelastischen Schicht 3 ein geformtes Profil auf. In vorteilhafter Weise weisen die Formprofile der elastischen Schicht 2 und der viskoelastischen Schicht 3 vorspringende Teile 5 und zurückstehende Teile 6 auf.As can be seen in FIG. 3, the surfaces of the elastic layer 2 and the viscoelastic layer 3 a shaped profile. Advantageously, the Shape profiles of the elastic layer 2 and viscoelastic layer 3 projecting parts 5 and protruding parts 6.

    Wie z.B. den Figuren 9 bis 11 zu entnehmen ist, weist das Teil 1 in einer bevorzugten Ausführungsform zwei oder mehrere unterschiedliche Verformungen 15,16 auf, um dadurch den entsprechenden Teilstücken unterschiedliche Stützfunktionen zu verleihen.Such as. FIGS. 9 to 11 show that Part 1 in a preferred embodiment two or several different deformations 15, 16 to thereby the corresponding sections different To provide support functions.

    So kann die unterschiedliche Formgebung durch Vorsehung von vorspringenden Teilen 5 und zurücktretenden Teilen 6 mit unterschiedlichen Abmessungen in jedem Abschnitt 15,16 vorgesehen sein.So the different shapes can be provided by projecting parts 5 and withdrawing parts 6 with different dimensions in each section 15, 16 be provided.

    Diese Maßnahme hat sich als vorteihaft erwiesen, um die Tragfähigkeit in Übereinstimmung mit verschiedenen Körperteilen des Benutzers z.B. in Übereinstimmung der Waden, des Nierenbereiches oder der Schultern zu erreichen. In besonders vorteilhafter Weise, wie dies in Figur 1 oder 3 dargestellt ist, weist die viskoelastische Schicht 3 abstehende Ränder oder Kanten 7 auf, die wenigstens teilweise die Seitenränder 8 der elastischen Schicht 2 abdecken. This measure has proven to be advantageous to the Load capacity in accordance with different Body parts of the user e.g. in accordance with the To reach the calves, the kidney area or the shoulders. In a particularly advantageous manner, as shown in FIG. 1 or 3, the viscoelastic layer 3 protruding edges or edges 7, at least partially the side edges 8 of the elastic layer 2 cover.

    Mit dieser Maßnahme wird der zweifache Vorteil erzielt, dass die Fläche des Polsterteiles 1 bei Berührung sehr gleichförmig erscheint, wie dies vom Endverbraucher gewünscht ist.With this measure, the double advantage is achieved that the surface of the cushion part 1 when touched appears uniform, as does the end user is desired.

    Ferner wird eine besonders stabile Verbindung zwischen der elastischen Schicht 2 und der viskoelastischen Schicht 3 erzielt, da neben der chemischen Verbindung auch eine mechanische Haltewirkung durch die Ränder 7 erreicht wird.Furthermore, a particularly stable connection between the elastic layer 2 and the viscoelastic layer 3 achieved because in addition to the chemical compound also mechanical holding effect is achieved by the edges 7.

    In Figur 14 ist ein Ausführungsbeispiel dargestellt, bei dem die elastische Schicht 2 in die viskoelastische Schicht 3 eingebettet ist.
