Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer Komponente einer Fahrzeugsitzstruktur für einen Kraftfahrzeugsitz oder einer Kraftfahrzeugstruktur, sowie einen Kraftfahrzeugsitz bzw. ein Kraftfahrzeug mit einer Struktur, die mehrere Komponenten aufweist, von denen wenigstens eine mittels eines solchen Verfahrens hergestellt worden ist.The The present invention relates to a process for the preparation of a Component of a vehicle seat structure for a motor vehicle seat or a motor vehicle structure, and a motor vehicle seat or a motor vehicle with a structure containing several components at least one of which by means of such a method has been produced.
Lehnenrahmen von Kraftfahrzeugsitzen bestehen häufig aus Metall und haben die Form eines auf dem Kopf stehenden U. Die Schenkel des Us werden als Längsholme bezeichnet, die durch einen Querholm verbunden sind. Der Lehnenrahmen wird bei longitudinalen Stößen auf das Fahrzeug am stärksten belastet, wenn die den Sitz benützende Person mit Rumpf und Kopf gegen Lehne und Kopfstütze geschleudert wird. Große Belastungen treten dabei insbesondere an den Verbindungsstellen zwischen Lehnen- und Sitzrahmen sowie an den Verbindungsstellen zwischen Lehnenrahmen und Kopfstütze auf.back frame Of motor vehicle seats are often made of metal and have the shape of an inverted U. The legs of the Us are referred to as longitudinal spars, which are connected by a cross member are. The backrest frame becomes with longitudinal joints on the vehicle most heavily loaded when the seat using person with torso and head against backrest and headrest is thrown. Great loads occur in particular at the joints between backrest and seat frame as well at the joints between backrest frame and headrest on.
Um Material und Gewicht zu sparen, sollten die Komponenten der tragenden Struktur des Fahrzeugsitzes an allen Stellen nur eine der jeweiligen Maximalbelastung angepasste Querschnittsfläche aufweisen. Bei den häufig verwendeten Lehnenrahmen, welche aus einem gebogenen Rundrohr gebildet werden, muss nachteilig eine durch die Stellen maximaler Belastung bedingte Mindestquerschnittsfläche auch an jenen Stellen beibehalten werden, an denen nur geringe Belastungen auftreten.Around To save material and weight, the components should be load-bearing Structure of the vehicle seat in all places only one of the respective Maximum load adapted cross-sectional area have. at the frequently used backrest frame, which consists of a curved Round tube must be formed, one disadvantageous by the bodies maximum load conditional minimum cross-sectional area be maintained even in those places where only low loads occur.
Bei Rahmen welche als Magnesium-Druckgussteil gefertigt sind, ist eine gute Anpassung der Querschnittsfläche an die zu erwartende Belastung möglich. Begrenzungen ergeben sich jedoch durch die gießtechnisch bedingte Mindestwandstärke des Bauteiles. Nachteilig sind auch die hohen Kosten der Gussform, der hohe Materialpreis, die geringe Duktilität von Gusslegierungen und der erforderliche hohe Aufwand zur Vermeidung bzw. Erkennung von Gießfehlern wie Lunkern oder Poren.at Frames which are made as a magnesium die-cast part, is a good adaptation of the cross-sectional area to the expected Load possible. However, limitations arise through the casting technology conditional minimum wall thickness of Component. Another disadvantage is the high cost of the mold, the high material price, the low ductility of cast alloys and the required high effort for avoidance or detection casting defects such as voids or pores.
Bei Rahmen, welche aus gefalteten und gebogen Blechen gebildet werden, ergeben sich Begrenzungen dadurch, dass Bleche an allen Stellen die gleiche Dicke haben. Eine große Blechdicke ist beispielsweise nur an den Verbindungsstellen des Lehnenrahmens mit dem Sitzrahmen und den Kopfstützenbügeln oder in den auf Biegung beanspruchten Zonen an den von der neutralen Faser weit entfernt liegenden Querschnittsbereichen erwünscht. An allen anderen Stellen wäre eine kleinere Wandstärke vorteilhaft, da dort keine größeren Belastungen auftreten.at Frames, which are formed from folded and bent sheets, Limitations arise from the fact that sheets in all places have the same thickness. For example, a large sheet thickness is only at the junctions of the backrest frame with the seat frame and the headrest straps or in the bend stressed zones at those far from the neutral fiber lying cross-sectional areas desired. At all other Make a smaller wall thickness would be advantageous because there are no major pressures.

Aufgabe der vorliegenden Erfindung ist es, eine Struktur für einen Kraftfahrzeugsitz oder ein Kraftfahrzeug und ein Verfahren zur Herstellung einer Komponente einer solchen Struktur zu verbessern.task The present invention is to provide a structure for a Motor vehicle seat or a motor vehicle and a method for manufacturing to improve a component of such a structure.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 bzw. 11 gelöst. Vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.These The object is solved by the features of claim 1 and 11, respectively. Advantageous embodiments of the invention are the subject the dependent claims.
Erfindungsgemäß werden eine oder mehrere Komponenten einer Struktur für einen Kraftfahrzeugsitz oder ein Kraftfahrzeug hergestellt, indem ein Ausgangsmaterial durch eine oder mehrere Matrizen durchgedrückt wird, um einen Profilstrang herzustellen. Insbesondere kann der Profilstrang mittels Fließpressen oder Strangpressen hergestellt werden.According to the invention one or more components of a structure for one Motor vehicle seat or a motor vehicle manufactured by a Feedstock pushed through one or more matrices is to make a profile strand. In particular, the Extruded profile produced by extrusion or extrusion become.
Anschließend wird, beispielsweise durch Sägen, insbesondere mit einer Bandsäge, Schneiden, insbesondere mit einem Laser, oder sonstiges Trennen ein Strangprofil von dem Profilstrang abgetrennt, welches dann als Halbzeug zu der Komponente umgeformt wird. Dies kann beispielsweise durch Druckumformen, insbesondere durch Freiformen, Gesenkformen wie insbesondere Schmieden, Eindrücken und/oder weiteres Durchdrücken, erfolgen. Zusätzlich oder alternativ kann das Strangprofil auch durch Zugdruckumformen, insbesondere durch Durchziehen, Tiefziehen, Drücken, Kragenziehen, Knickbauchen und/oder Innenhochdruck-Weitstauchen zu der Komponente umgeformt werden. Weiter zusätzlich oder alternativ kann das Strangprofil auch durch Zugumformen, insbesondere durch Längen und/oder Weiten, und/oder durch Biegeumformen, insbesondere durch Freies Biegen und/oder Gesenkbiegen, zu der Komponente umgeformt werden.Subsequently is, for example by sawing, especially with a Band saw, cutting, especially with a laser, or otherwise separating an extruded profile from the profiled strand, which is then formed as a semi-finished product to the component. This For example, by pressure forming, in particular by free-form, Die forms such as in particular forging, impressions and / or further pressing, done. Additionally or Alternatively, the extruded profile can also by Zugdruckumformen, in particular by pulling, deep drawing, pressing, collar pulling, buckling and / or hydroforming extensively formed into the component become. Next additionally or alternatively, the extruded profile also by tensile forming, in particular by lengths and / or Widths, and / or by bending, especially by free Bending and / or bending, to which component will be reshaped.
Erfindungsgemäß wird bereits beim Durchdrücken des Ausgangsmaterials durch eine oder mehrere Matrizen eine variierende Wandstärke des Strangprofils ausgebildet, so dass dieses schon vor dem weiteren Umformen eine variierende Wandstärke quer zur Durchdrückrichtung aufweist.According to the invention already by pressing the starting material through a or more matrices a varying wall thickness of the extruded profile trained so that this one before further forming a varying wall thickness across the push-through direction having.
Dadurch können bei der Herstellung einer Strukturkomponente vorteilhaft ein oder mehrere zusätzliche Walz- oder Schweißschritte nach dem Durchdrücken entfallen, was die Herstellkosten und -zeit verringert.Thereby may be advantageous in the preparation of a structural component one or more additional rolling or welding steps omitted after pushing through what the manufacturing costs and time reduced.
Auf der anderen Seite können so bedarfsgerecht höher belastete Bereiche mit größeren Wandstärken und somit sicherer, weniger belastete Bereiche mit geringeren Wandstärken und somit leichter und materialsparender ausgebildet werden, ohne dass hierfür ein weiterer Arbeitsschritt zwischen dem Durchdrücken und dem Umformen in die Komponente der Struktur erforderlich ist.On The other side can be as needed higher loaded areas with larger wall thicknesses and thus safer, less stressed areas with smaller wall thicknesses and thus be made easier and more material-saving, without that for this another step between the pressing and forming in the component of the structure is required.
Durch ein erfindungsgemäßes Verfahren kann insbesondere eine Quertraverse einer rahmenartigen Rückenlehnenstrukur hergestellt werden, wobei das Strangprofil dann vorteilhaft wenigstens im Bereich einer Kopfstützenaufnahme eine größere Wandstärke aufweist.By a method according to the invention can in particular a crossbeam of a frame-like Rückenlehnenstrukur be prepared, the extruded profile then advantageously at least in the area of a headrest receptacle a larger one Wall thickness has.
Gleichermaßen kann durch ein erfindungsgemäßes Verfahren beispielsweise auch eine Sitzschale hergestellt werden, wobei das Strangprofil dann vorteilhaft wenigstens im Bereich einer Lagerstelle, insbesondere eines verstellbaren Drehgelenks zur Anlenkung einer Rückenlehne, eine größere Wandstärke aufweist. Alternativ können durch ein erfindungsgemäßes Verfahren auch andere Komponenten einer Kraftfahrzeugstruktur, beispielsweise Karosserie- oder Verkleidungskomponenten, hergestellt werden equally can for example by a method according to the invention also a seat shell are produced, wherein the extruded profile then advantageously at least in the area of a bearing, in particular an adjustable swivel joint for the articulation of a backrest, has a greater wall thickness. alternative can by a method according to the invention also other components of a motor vehicle structure, for example Bodywork or trim components are manufactured
Hinsichtlich der Verarbeitbarkeit im Durchdrückverfahren, der Festigkeit und des Gewichts ist insbesondere Magnesium oder eine Legierung von Magnesium als Ausgangsmaterial vorteilhaft. Insbesondere hierbei kann es vorteilhaft sein, das Strangprofil mittels Warmumformen, vorzugsweise unter Nutzung einer Erwärmung vor oder bei dem Durchdrücken durch die Matrize, zu der Komponente umzuformen. Gegenüber bisherigen Verfahren, bei denen zunächst Magnesiumbleche mit homogener Wandstärke stranggepreßt oder -gossen und diese Bleche später kaltumgeformte werden, ermöglicht die Warmumformung des noch vom Stranggieß- bzw. -preßvorgang warmen Strangprofils eine bessere Umformbarkeit, ein besseres Gefüge und/oder die Einsparung von Energie.Regarding the processability in the Durchdrückverfahren, the strength and the weight is especially magnesium or an alloy of magnesium as starting material advantageous. Especially here it may be advantageous to use the extrusion profile by hot forming, preferably using heating before or at pushing through the die to reshape the component. Compared to previous methods, where initially Magnesium sheets with homogenous wall thickness extruded or -gossen and these sheets are later cold-formed, allows the hot forming of the still from the continuous casting or -pressing warm strand profile better formability, a better structure and / or the saving of energy.
Nach einer bevorzugten Ausführung weist der Profilstrang beim Durchdrücken durch die Matrize eine geringere Breite auf als die fertige Komponente. So kann beispielsweise zunächst ein Blech mit geringerer Breite hergestellt und anschließend, insbesondere in Bereichen größerer Wandstärken, durch Umformen, vorzugsweise Warmumformen, insbesondere unter Nutzung einer Erwärmung vor oder bei dem Durchdrücken durch die Matrize, verbreitert werden, was die Herstellung breiterer Strukturkomponenten mit schmaleren Matrizen ermöglicht. Weitere vorteilhafte Weiterbildungen der vorliegenden Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung bevorzugter Ausführungen. Hierzu zeigt, teilweise schematisiert:To a preferred embodiment, the profile strand in Push through the die on a smaller width as the finished component. For example, first made a sheet with a smaller width and then, especially in areas of greater wall thickness, by forming, preferably hot forming, in particular under use a warming before or during the push through the die, widened, resulting in the production of wider structural components with narrower matrices. Further advantageous Further developments of the present invention will become apparent from the Subclaims and the description below is more preferred Versions. This shows, partially schematized:
