Abstract

The invention relates to a method and a device for constructing a vehicle seat made of an upholstery body and an upholstery covering by means of a data processing system. Said inventive method comprises the following steps: inputting standard data defining a theoretical form of the upholstery body (theoretical upholstery body); digitisation of the theoretical upholstery body to form a design model; calculating the cut of the upholstery body based on the design model; calculating the force of the covering acting on the design model which is virtually provided with the upholstery covering provided on the design model; calculating the necessary modifications of the design model dependent on the covering forces in order to produce a practical model which corresponds to the uncovered covering acting on the design model which is virtually provided with the upholstery body and which has the predetermined theoretical form of the upholstery body once the upholstery is applied.

Description

Verfahren und Vorrichtung zur Konstruktion eines FahrzeugsitzesMethod and device for constructing a vehicle seat
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Konstruktion eines Fahrzeugsitzes bestehend aus einem Polsterkörper und einem Polsterbezug. Grundproblem bei der Entwicklung eines Polsterkörpers sind die Bezugskräfte, die durch den Druck des Polsterbezugs auf den meistens als Schaumteil ausgebildeten Polsterkörper wirken. Der Konstrukteur eines Fahrzeugsitzes muss daher insbesondere an straffgezogenen Stellen (z. B. Wulst) das Schaumteil bzw. den Polsterkörper aufdicken, um die Schaumeindrückung zu kompensieren und damit die Designvorgabe zu erfüllen.The invention relates to a method and a device for constructing a vehicle seat consisting of an upholstery body and an upholstery cover. The basic problem in the development of an upholstered body is the reference forces which act on the upholstery body, which is usually designed as a foam part, due to the pressure of the upholstery cover. The designer of a vehicle seat must therefore thicken the foam part or the upholstered body, particularly at taut points (e.g. bulge), in order to compensate for the foam indentation and thus to meet the design specification.
Bei den bisher bekannten Verfahren werden die Verfahrensschritte zur Konstruktion des Polsterkörpers und die Verfahrensschritte zur Konstruktion des Polsterbezugs, insbesondere zur Erzeugung der Bezugszuschnitte, nacheinander, d.h. auch getrennt voneinander, durchgeführt. Es wird also bisher basierend auf der Soll-Form eines Polsterkörpers unter Berücksichtung von Materialkenndaten, wie z. B. Bezugsmaterialstärke, Schaumfestigkeit usw., anhand von Erfahrungswerten zunächst ein unbezogener und damit entspannter Polsterkörper konstruiert. Gegebenenfalls wird der fertig konstruierte Polsterkörper in Form eines 3D- Modells digital als Eingangsgröße für die Verfahrensschritte zur Erzeugung des Polsterbezugs zur Verfügung gestellt. Aus diesem 3D-Modell werden 2D-Bezugszuschnitte für den Polsterbezug berechnet. Die einzelnen Bezugszuschnitte des Polsterbezugs werden ebenfalls getrennt voneinander berechnet. Eine Komfortbeurteilung wird manuell am tatsächlich mit dem Polsterbezug versehenen Polsterkörper vorgenommen. Ist der Komfort nicht akzeptabel, müssen meistens sowohl der Polsterkörper als auch der Polsterbezug modifiziert werden.In the previously known methods, the method steps for the construction of the upholstery body and the method steps for the construction of the upholstery cover, in particular for producing the reference blanks, are carried out in succession, ie also separately from one another. So far it is based on the target shape of a cushion body taking into account material characteristics, such as. B. reference material thickness, foam strength, etc., based on empirical values, initially constructed an unrelated and thus relaxed cushion body. If necessary, the fully constructed upholstered body is in the form of a 3D Model digitally provided as an input variable for the process steps for producing the upholstery cover. 2D reference blanks for the upholstery cover are calculated from this 3D model. The individual cover cuts of the upholstery cover are also calculated separately. A comfort assessment is carried out manually on the cushion body that is actually provided with the cushion cover. If the comfort is not acceptable, both the upholstery body and the upholstery cover usually have to be modified.
Es ist Aufgabe der Erfindung, ein Verfahren und eine Vorrichtung zur Konstruktion eines Fahrzeugsitzes bestehend aus einem Polsterkörper und einem Polsterbezug einerseits zu vereinfachen und andererseits zu optimieren.It is an object of the invention to simplify on the one hand and to optimize a method and a device for constructing a vehicle seat consisting of an upholstery body and an upholstery cover.
Diese Aufgabe wird durch die Merkmale der Patentansprüche 1 und 2 gelöst.This object is solved by the features of claims 1 and 2.
Zur näheren Erläuterung der Erfindung ist in der Zeichnung ein Ausführungsbeispiel der Erfindung dargestellt. Hierin werden insbesondere die durch die Erfindung entstehenden Zusammenhänge zwischen den Verfahrensschritten zur Konstruktion des Polsterkörpers (Prozesskette Polsterkörper) und den Verfahrensschritten zur Konstruktion des Polsterbezugs bzw. der Bezugszuschnitte (Prozesskette Polsterbezug) verdeutlicht.For a more detailed explanation of the invention, an embodiment of the invention is shown in the drawing. In particular, the relationships between the process steps for the construction of the upholstery body (process chain upholstery body) and the process steps for the construction of the upholstery cover or the cover blanks (process chain upholstery cover) are clarified.
Das Ausführungsbeispiel bezieht sich auf einen Fahrzeugsitz, dessen Polsterkörper aus einem Oberpolster und einem Unterpolster zusammengesetzt wird. Eine derartige zweiteilige Ausgestaltung eines Polsterkörpers mit seinen Vorteilen ist beispielsweise aus der DE 197 51 091 A1 bereits bekannt. In der Zeichnung ist schematisch eine digitale Bibliothek 1 zur Auswahl eines sitzmechanik-angepassten Unterpolsters dargestellt. DieThe exemplary embodiment relates to a vehicle seat, the cushion body of which is composed of an upper cushion and a lower cushion. Such a two-part design of an upholstered body with its advantages is already known, for example, from DE 197 51 091 A1. In the drawing, a digital library 1 for the selection of a seat cushion adapted to the seat mechanism is shown schematically. The
Ausgangsinformation der digitalen Bibliothek 1 ist ein digitalisiertes Unterpolster 2 zur Vorgabe einer Soll-Form des Unterteils des Polsterkörpers. Ausgangsinformation eines hier nicht dargestellten Design- Computers ist ein digitalisiertes Oberpolster 4 zur Vorgabe der Soll-Form des Oberteils des Polsterkörpers. Das digitalisierte Oberpolster 4 kann beispielsweise eine Fläche wiedergeben, die auch als parametrisierte A- Fläche bezeichnet wird. Das digitalisierte Unterpolster 2 kann beispielsweise ebenfalls eine Fläche darstellen, die auch als parametrisierte B-Fläche bezeichnet wird. Das digitalisierte Oberpolster 4, das digitalisierte Unterpolster 2, die Ausgangsinformation eines Nahtbilderzeugers 10 und Materialkenndaten, wie z. B. die Materialstärke des Polsterbezugs, die Nachgiebigkeit des Polsterbezugs, sowie die Nachgiebigkeit bzw. Festigkeit des Polsterkörpers in Form eines Schaumteils, sind Eingangsinformationen des Design-Modellerzeugers 3. Im Design-Modellerzeuger 3 wird unter Berücksichtigung der Eingangsinformationen der gesamte (überzogene) Soll-Polsterkörper zu einem Design-Modell digitalisiert. Ein derartiges digitalisiertes Design-Modell ist insbesondere ein 3-dimensionales FE- Modell, durch das Körper in Form von finiten Elementen 3-dimensional visualisiert werden können. Im Design-Modell können beispielsweise auch Schaumhärtezonen, mit dem Bezug vernähte bzw. nichtvernähte Blockschaumauflagen, Anbauteile und/oder Sitzbreiten-Verstellmöglichkeiten (als FE-Elemente) berücksichtigt werden.The output information from the digital library 1 is a digitized sub-cushion 2 for specifying a desired shape of the lower part of the cushion body. The output information of a design computer, not shown here, is a digitized upper cushion 4 for specifying the desired shape of the upper part of the cushion body. The digitized top cushion 4 can, for example, represent a surface that is also referred to as a parameterized A surface. The digitized sub-cushion 2 can, for example, also represent an area which is also referred to as a parameterized B area. The digitized upper cushion 4, the digitized lower cushion 2, the output information of a seam image generator 10 and material characteristics, such as. B. The material thickness of the upholstery cover, the compliance of the upholstery cover, as well as the compliance or strength of the upholstery body in the form of a foam part, are input information from the design model generator 3. Upholstered body digitized into a design model. Such a digitized design model is in particular a 3-dimensional FE model, through which bodies in the form of finite elements can be visualized in 3 dimensions. In the design model, for example, foam hardness zones with the cover sewn or non-sewn block foam pads, attachments and / or seat width adjustment options (as FE elements) can also be taken into account.
Aufgrund des Design-Modells, zumindest aufgrund des dem Oberpolster entsprechenden Teils des Design-Modells, und vorzugsweise auch aufgrund der Ausgangsinformation des Nahtbilderzeugers 10 wird im Zuschnittaufteiler 5 ein vorteilhafter Zuschnitt des Polsterbezugs festgelegt. In einem Faltenberechner 6 kann ebenfalls unter Berücksichtigung des Design- Modells, eine Bezugsfaltenanalyse vorgenommen werden. Fällt die Bezugsfaltenanalyse negativ aus, da beispielsweise zu viele Falten oder Falten an ungewünschten Stellen auftreten, kann im Zuschnittaufteiler 5 eine Modifizierung vorgenommen werden. Es könnte auch eine Modifizierung an anderer Stelle, z. B. am Design-Modell bzw. an den Soll-Formen vorgenommen werden (hier nicht dargestellt). Fällt die Bezugsfaltenanalyse positiv aus, werden im Zuschnittsberechner 7 die Bezugskräfte, also die auf den Polsterkörper wirkenden Kräfte nach dem Bezug, eine exakte Randbespannung und der Bezugszuschnitt für die Zuschneidemaschine 8 (Cutter) berechnet.On the basis of the design model, at least on the basis of the part of the design model corresponding to the upper cushion, and preferably also on the basis of the output information from the seam image generator 10, an advantageous cutting of the cushion cover is defined in the cut-out divider 5. A reference fold analysis can also be carried out in a fold calculator 6, taking into account the design model. Does that fall Reference fold analysis negative, because, for example, too many folds or folds occur at undesired locations, a modification can be made in the blank divider 5. A modification elsewhere, e.g. B. on the design model or on the target shapes (not shown here). If the reference fold analysis is positive, the reference forces, that is to say the forces acting on the cushion body after the cover, an exact edge covering and the reference blank for the cutting machine 8 (cutter) are calculated in the cutting calculator 7.
Erfindungswesentlich ist, dass die im Zuschnittsberechner 7 der Prozesskette Polsterbezug ermittelten Bezugskräfte Eingangssignale des Werkzeug-Modellerzeugers 11 in der Prozesskette Polsterkörper sind. Im Werkzeug-Modellerzeuger 11 wird das Design-Modell des Polsterkörpers einschließlich den entsprechenden Materialkenndaten mit diesen Bezugskräften virtuell belastet. Hierdurch erhält das Design-Modell eine Geometrie, die durch das Beziehen mit dem Polsterbezug entsteht. Im optimalen Fall, insbesondere wenn die Bezugskräfte gegen Null gehen, wird das Design-Modell nicht verändert. In der Realität trifft dies jedoch meistens durch die teilweise Unnachgiebigkeit des Polsterbezugs nicht zu. Daher wird im Werkzeug-Modellerzeuger 11 das Design-Modell abhängig von den Bezugskräften modifiziert, insbesondere aufgedickt, um ein Werkzeug- Modell zu erhalten, das dem unbezogenen, also entspannten Polsterkörper entspricht und das im bezogenen Zustand, also mit dem Polsterbezug die vorgegebene Soll-Form des Polsterkörpers erhält. Die Modifizierung des Design-Modells im Werkzeug-Modellerzeuger 11 wird anhand bekannter FE- Verfahren durchgeführt. Der automatische Modifizierungsvorgang im Werkzeug-Modellerzeuger 11 kann mehrmals iterativ durchgeführt werden, bis eine vorher festgelegte Abweichung des virtuell bezogenen Werkzeug- Modells zum Design-Modell erreicht ist. Optional können im Druckermittler 12 Informationen, wie z. B. der sogenannte H-Punkt oder die Sitzdruckverteilung, zur Erzeugung von Größen zur Komfortbeurteilung berechnet werden. Fällt die Komfortbeurteilung negativ aus, kann beispielsweise eine Veränderung oder eine andere Auswahl des digitalisierten Unterpolsters 2 vorgenommen werden. Fällt die Komfortbeurteilung positiv aus, werden die Daten des Werkzeug-Modells z. B. an einen Polsterkörperfräser (oder Werkzeugfräser) 13 weitergegeben. Im Polsterkörperfräser 13 wird der unbezogene Polsterkörper hergestellt, der in der Bezugseinheit 9 mit den von der Zuschneidemaschine 8 erhaltenen Zuschnitten fertig bezogenen wird.It is essential to the invention that the reference forces determined in the cutting calculator 7 of the upholstery process chain are input signals of the tool model generator 11 in the upholstery process chain. In the tool model generator 11, the design model of the upholstery body, including the corresponding material data, is virtually loaded with these reference forces. This gives the design model a geometry that is created by covering it with the upholstery. In the optimal case, especially when the reference forces approach zero, the design model is not changed. In reality, however, this is mostly not the case due to the partial intransigence of the upholstery cover. Therefore, in the tool model generator 11, the design model is modified depending on the reference forces, in particular thickened, in order to obtain a tool model which corresponds to the unrelated, that is to say relaxed, upholstery body and which, in the related state, that is to say with the upholstery cover, the predetermined target Shape of the upholstered body is preserved. The modification of the design model in the tool model generator 11 is carried out using known FE methods. The automatic modification process in the tool model generator 11 can be carried out iteratively several times until a predefined deviation of the virtually related tool model from the design model has been reached. Optionally, information such as e.g. B. the so-called H-point or the seat pressure distribution can be calculated to generate variables for comfort assessment. If the comfort assessment is negative, a change or a different selection of the digitized sub-cushion 2 can be carried out, for example. If the comfort rating is positive, the data of the tool model are e.g. B. passed on to an upholstered body milling cutter (or tool milling cutter) 13. The unrelated upholstery body is produced in the upholstery milling cutter 13 and is finished in the reference unit 9 with the blanks obtained from the cutting machine 8.
Erfindungswesentlich an diesem Ausführungsbeispiel ist insbesondere, dass die Prozesskette Polsterkörper und die Prozesskette Polsterbezug sich gegenseitig beeinflussen. Insbesondere benötigt der Zuschnittsberechner 7 in der Prozesskette Polsterbezug Daten aus dem Design-Modellerzeuger 3 aus der Prozesskette Polsterkörper. Der Werkzeug-Modellerzeuger 11 aus der Prozesskette Polsterkörper wiederum benötigt die Ausgangssignale Bezugskräfte des Zuschnittsberechners 7 aus der Prozesskette Polsterbezug. Durch dieses erfindungsgemäße Verfahren werden virtuelle Optimierungsvorgänge durchgeführt, wodurch eine optimierte Konstruktion von Polsterkörper und Polsterbezug erreicht wird. Alle Verfahrensschritte können in einer einzigen Datenverarbeitungsanlage durchgeführt werden. Eine Konvertierung von digitalisierten Daten entfällt. Weiterhin verkürzt sich aufgrund des erhöhten Automatisierungsgrades die Arbeitszeit. Essential to the invention in this exemplary embodiment is, in particular, that the process chain cushion body and the process chain cushion cover mutually influence one another. In particular, the cutting calculator 7 requires data from the design model generator 3 in the process body upholstery in the process chain upholstery cover. The tool model generator 11 from the upholstery body process chain in turn requires the output signals reference forces of the cutting computer 7 from the upholstery process chain. By means of this method according to the invention, virtual optimization processes are carried out, whereby an optimized construction of the upholstery body and upholstery cover is achieved. All process steps can be carried out in a single data processing system. There is no conversion of digitized data. Furthermore, the working time is reduced due to the increased degree of automation.
