Description

Die Erfindung betrifft einen Einzugstab zur Profilformung von außenseitig durch einen Bezugstoff abgedeckten Polstermaterialien bei Polstermöbeln und dgl. gepolsterten Sitzteilen, bestehend aus einem eine gesondert hergestellte Annähfahne für seine Verbindung mit dem Bezugstoff tragenden Profilkörper aus Kunststoff, der ein zweischenkeliges Querschnittsprofil aufweist, dessen beide Profilschenkel an ihrer Basis durch einen schmalen Verbindungssteg miteinander verbunden sind und einen von diesem ausgehenden, die Annähfahne mit einem ihrer Seitenränder festlegenden Aufnahmespalt begrenzen, wobei einer der beiden Profilschenkel beidendig mit einstückig angeformten seitlichen Halteleisten versehen ist.The invention relates to a draw-in bar for shaping the profile of upholstery materials covered on the outside by a cover material in upholstered furniture and the like their base are connected to each other by a narrow connecting web and define a receiving gap starting from the latter, which defines the sewing flag with one of its side edges, one of the two profile legs being provided at both ends with integrally molded lateral retaining strips.

Derartige Einzugstäbe werden bei Polstermöbeln, aber auch bei anderen gepolsterten Sitzteilen, wie insbesondere Autositzen einschl. deren Rückenlehnen, dazu verwandt, das auf einer geeigneten Unterlage angebrachte Polstermaterial in die gewünschte, sitz- bzw. körpergerechte Form zu bringen. Der Bezugstoff wird dabei an die Annähfahne des Profilkörpers angenäht, und der so vorbereitete Einzugstab wird sodann im wesentlichen quer zur äußeren Oberfläche des auf dem Polstermaterial aufliegenden Bezugstoffes in das Polstermaterial hineingezogen und festgelegt, wodurch eine nahtähnliche sog. Blindabheftung oder Blindnaht mit entsprechenden Profilwölbungen beidseits der Blindnaht erzeugt wird.Such pull-in rods are used in upholstered furniture, but also in other upholstered seat parts, such as, in particular, car seats including their backrests, to bring the upholstery material attached to a suitable base into the desired shape that is appropriate for the seat or body. The cover fabric is sewn onto the sew-on tab of the profile body, and the feed rod prepared in this way is then drawn into and fixed in the upholstery material essentially transversely to the outer surface of the cover fabric lying on the upholstery material, whereby a seam-like so-called blind stitching or blind seam with corresponding profile curvatures on both sides of the Blind seam is generated.

Bei einem bekannten Einzugstab der angegebenen Art bilden die an den einen der beiden Profilschenkel angeformten seitlichen Halteleisten in der praktischen Anwendung des Einzugstabes eine unterseitige Abstützung von etwa Nahtlänge durch Anlage an einer entsprechenden der Blindnaht gegenüberliegenden Polstermaterialfläche zur Festlegung des über die Annähfahne eingezogenen oberseitigen Bezugstoffes des gepolsterten Sitzteils, z.B. eines Autositzes. Das Polstermaterial dieser Sitzteile besteht üblicherweise aus Schaumstoff, z.B. Polyurethanschaum, wobei für eine ausreichende Festigkeit und Formhaltigkeit des Sitzteils häufig Stahldrahtstäbe oder dgl. Metallteile in das Schaummaterial eingeschäumt werden. Sofern solche miteingeschäumten Metallteile, etwa im Interesse einer problemlosen Entsorgung gebrauchter oder beschädigter Sitzteile zum Beispiel im Recycling, vermieden werden sollen, ist die Möglichkeit der Profilformung der Sitzteile mit den bekannten Einzugstäben eingeschränkt, da sich die Annähfahne von der Oberseite des Polstermaterials bis zu dessen Unterseite durch einen entsprechenden Trennschlitz im Polstermaterial hindurcherstreckt, wobei eine Vielzahl solcher das Polstermaterial unterteilender Trennschlitze der Festigkeit und Formstabilität des Sitzteils abträglich sind.In a known pull-in bar of the specified type, the lateral retaining strips formed on one of the two profile legs in practical use of the pull-in bar form an underside support of approximately the seam length by contacting a corresponding pad material surface opposite the blind seam for fixing the upholstery upholstery material drawn in via the sewing flag Seat part, e.g. of a car seat. The upholstery material of these seat parts usually consists of foam, e.g. Polyurethane foam, steel wire rods or the like. Metal parts are often foamed into the foam material for sufficient strength and shape retention of the seat part. If such foamed-in metal parts are to be avoided, for example in the interest of problem-free disposal of used or damaged seat parts, for example in recycling, the possibility of profiling the seat parts with the known draw-in rods is restricted, since the sewing tab extends from the top of the upholstery material to the underside extends through a corresponding separating slot in the upholstery material, a large number of such separating slots dividing the upholstery material being detrimental to the strength and dimensional stability of the seat part.

Der Erfindung liegt die Aufgabe zugrunde, einen Einzugstab der eingangs angegebenen Art zu schaffen, der insbesondere bei Sitzteilen aus Schaumstoff ohne eingeschäumte Metallarmierung verwendet werden kann, um in gewohnter Weise durchlaufende, sauber konturierte Blindabheftungen oder Blindnähte im Polstermaterial zu erzeugen, ohne daß dieses in unerwünschter Weise geschwächt wird.The invention has for its object to provide a feed rod of the type specified, which can be used in particular with seat parts made of foam without foamed metal reinforcement in order to produce continuous, cleanly contoured blind stitching or blind seams in the upholstery material without this being undesirable Way is weakened.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß der Einzugstab mit in seiner Längsrichtung mit Abstand voneinander angeordneten, durch die Annähfahne einbeziehende Ausstanzungen gebildeten Haltelaschen versehen ist und die Annähfahne im Bereich ihres dem Aufnahmespalt gegenüberliegenden freien Seitenrandes einen in Längsrichtung des Einzugstabs durchlaufenden, die Ausstanzungen überbrückenden, seinerseits aus Kunststoff bestehenden Stützstab trägt. Bei dieser Ausgestaltung sind die seitlichen Halteleisten des einen, äußeren Profilschenkels durch die vorgenommenen Ausstanzungen auf einzelne Haltelaschen verkürzt, die durch entsprechend konturierte einzelne Formausnehmungen im Polstermaterial, insbesondere Schaumstoff, hindurchgezogen werden können, ohne daß durch diese einzelnen Formausnehmungen eine nennenswerte Schwächung des Schaumstoffmaterials eintritt.This object is achieved according to the invention in that the pull-in bar is provided with holding tabs arranged in its longitudinal direction at a distance from one another and formed by punch-outs incorporating the sewing-in flag, and the sew-on tab in the region of its free side edge opposite the receiving gap has a punch-out in the longitudinal direction of the pull-in bar bridging, in turn Plastic existing support rod. In this embodiment, the lateral retaining strips of the one, outer profile leg are shortened by the punched-outs to individual retaining tabs, which can be pulled through appropriately contoured individual shape recesses in the upholstery material, in particular foam, without any significant weakening of the foam material occurring through these individual shape recesses.

Der Profilkörper liegt dann in der praktischen Anwendung nur im Bereich dieser Formausnehmungen mit den Haltelaschen rück- bzw. unterseitig am Polstermaterial an. Etwaigen Ausbeulungen oder Verformungen der oberseitigen Blindnaht, die durch die rück- bzw. unterseitig nicht abgestützten, von den Ausstanzungen des Profilkörpers definierten Bereiche verursacht werden könnten, wirkt der in Längsrichtung der Annähfahne durchlaufende, die Ausstanzungen überbrückende Stützstab entgegen. Es können daher mit Hilfe des Einzugstabs nach der Erfindung in gewohnter Weise sauber konturierte Blindnähte, insbesondere bei Sitzteilen aus Schaumstoff ohne Innenarmierung, hergestellt werden. Grundsätzlich kann der Einzugstab nach der Erfindung auch bei anderen Polsterungen bzw. Unterfederungen, zum Beispiel solchen aus Gewebe, Anwendung finden.The profile body then lies in practical use only in the area of these recesses with the retaining tabs on the back or underside of the upholstery material. Any bulges or deformations of the top blind seam, which could be caused by the areas not supported on the back or underside, which are defined by the punched-out sections of the profile body, are counteracted by the support rod, which runs in the longitudinal direction of the sewing flag and bridges the punched-out section. Therefore, with the help of the pull-in bar according to the invention, cleanly contoured blind seams can be produced in the usual way, in particular in the case of seat parts made of foam without internal reinforcement. In principle, the pull-in bar according to the invention can also be used with other upholstery or spring bases, for example, made of fabric.

Der in Fig. 1 mit einem Teilstück dargestellte, als Ganzes mit 1 bezeichnete Einzugstab geht aus von einem einstückig stranggepreßten Profilkörper aus beispielsweise Polypropylen mit einem zweischenkeligen Querschnittsprofil, dessen beide Profilschenkel 2 und 3 an ihrer Basis durch einen schmalen Verbindungssteg 4 miteinander verbunden sind. Ausgehend von dem Verbindungssteg 4 begrenzen die beiden Profilschenkel 2 und 3 einen eine gesondert hergestellte Annähefahne 5 aufnehmenden Aufnahmespalt, in dem die Annähfahne 5 durch Verschweißung festgelegt ist.The pull-in bar shown in FIG. 1 with a section, designated as a whole by 1, is based on one piece extruded profile body made of, for example, polypropylene with a two-legged cross-sectional profile, the two profile legs 2 and 3 of which are connected to one another at their base by a narrow connecting web 4. Starting from the connecting web 4, the two profile legs 2 and 3 delimit a receiving gap which receives a separately produced sewing flag 5 and in which the sewing flag 5 is fixed by welding.

Die Annähfahne 5 besteht aus einem Vlies, Gittergewebe oder dgl. textilem mit dem Einzugstab 1 gut verschweißbaren Material und füllt den Aufnahmespalt mit einem ihrer Seitenränder voll aus.The sew-on flag 5 consists of a fleece, mesh fabric or the like. Textile that can be easily welded to the feed rod 1 and fills the receiving gap completely with one of its side edges.

Der Profilschenkel 3 ist beidendig mit einstückig angeformten seitlichen Halteleisten 6 und 7 versehen, wobei der Verbindungssteg 4 im Bereich des Profilschenkels 3 den Übergang zwischen diesem und der seitlichen Halteleiste 6 bildet. Zu einem mittleren Firstbereich hin sind die Halteleisten 6 und 7 unter Einbeziehung des Profilschenkels 3 verdickt ausgebildet.The profile leg 3 is provided at both ends with integrally molded lateral retaining strips 6 and 7, the connecting web 4 forming the transition between the latter and the lateral retaining strip 6 in the region of the profile leg 3. The holding strips 6 and 7 are formed thickened with the inclusion of the profile leg 3 towards a central ridge area.

Der Einzugstab 1 ist mit in seiner Längsrichtung einen Abstand voneinander einhaltenden Ausstanzungen 8 versehen, die die zuvor eingeschweißte Annähfahne 5 mit einbeziehen. Es sind auf diese Weise Haltelaschen 9 zwischen den Ausstanzungen 8 und an den Enden des Einzugstabs 1 gebildet, die als Halteteile jeweils den Profilschenkel 3 mit den seitlich angeformten Halteleisten 6 und 7 umfassen.The feed rod 1 is provided with punched-out punchings 8 which keep a distance from one another in its longitudinal direction and which include the previously welded-in sewing tab 5. In this way, retaining tabs 9 are formed between the punched-out portions 8 and at the ends of the pull-in bar 1, each of which, as retaining parts, comprises the profile leg 3 with the laterally molded retaining strips 6 and 7.

Im Bereich ihres den Profilschenkeln 2 und 3 gegenüberliegenden freien Seitenrandes 10 trägt die Annähfahne 5 einen in ihrer Längsrichtung durchlaufenden Stützstab 11, der die Ausstanzungen 8 überbrückt. Der Stützstab 11 ist dabei angrenzend an die miteinander fluchtenden Grundlinien 12 der Ausstanzungen 8 und mit parallelem Abstand vom freien Seitenrand 10 der Annähfahne 5 auf einer ihrer beiden Oberflächenseiten festgelegt. Bei dem dargestellten Beispiel ist der Stützstab 11 auf der dem Halteschenkel 7 der Haltelaschen 9 zugewandten Oberflächenseite der Annähfahne 5 festgelegt.In the area of its free side edge 10 opposite the profile legs 2 and 3, the sewing flag 5 carries a support rod 11 which extends in its longitudinal direction and bridges the punched-out portions 8. The support rod 11 is fixed adjacent to the mutually aligned base lines 12 of the punched-outs 8 and at a parallel distance from the free side edge 10 of the sewing flag 5 on one of its two surface sides. In the example shown, the support rod 11 is fixed on the surface side of the sewing flag 5 facing the holding leg 7 of the holding tabs 9.

Der Stützstab 11 besitzt ein Vollprofil, insbesondere ein abgerundetes Rechteckprofil, und weist dabei eine an der Annähfahne 5 anliegende Flachseite auf, die als Verbindungsfläche dient. Der Stützstab 11 besteht seinerseits aus einem gesondert hergestellten Strangprofilkörper, der vorteilhaft mit der Annähfahne nahe deren freiem Rand 10 verschweißt ist. Vorteilhaft sind die Haltelaschen 9 bzw. der diese mit Hilfe der Ausstanzungen 8 bildende Strangprofilkörper, die Annähfahne 5 und der Stützstab 11 sämtlich aus dem gleichen bzw. einem gleichartigen gut verschweißbaren Kunststoff gebildet. Dies gewährleistet eine gute gegenseitige Verschweißung dieser drei Teile des Einzugstabs 1.The support rod 11 has a full profile, in particular a rounded rectangular profile, and in this case has a flat side which bears against the sewing flag 5 and serves as a connecting surface. The support rod 11 in turn consists of a separately produced extruded profile body, which is advantageously welded to the sewing flag near its free edge 10. Advantageously, the retaining tabs 9 or the extruded profile body forming them with the aid of the punchings 8, the sewing tab 5 and the support rod 11 are all made of the same or a similar, easily weldable plastic. This ensures good mutual welding of these three parts of the feed rod 1.

Zwischen dem Stützstab 11 und dem freien Rand 10 der Annähfahne ist ein Randbereich 13 der Annähfahne 5 gebildet, der zum Annähen an den jeweiligen Bezugstoff 14 (Fig. 2) verwendet wird. Fig. 2 zeigt die Verbindung des Bezugstoffes 14 mit der Annähfahne 5 mittels einer Nähnaht 15, die unmittelbar an den Stützstab 11 angrenzt. Der Bezugstoff 14 ist in diesem Bereich nach innen, in das Polstermaterial 16 hinein eingezogen und bildet eine profilformende Blindabheftung bzw. Blindnaht.Between the support rod 11 and the free edge 10 of the sewing flag an edge region 13 of the sewing flag 5 is formed, which is used for sewing on the respective cover fabric 14 (FIG. 2). Fig. 2 shows the connection of the cover fabric 14 with the sewing flag 5 by means of a sewing seam 15 which is directly adjacent to the support rod 11. In this area, the cover fabric 14 is drawn inwards into the cushion material 16 and forms a profile-forming blind stitching or blind seam.

Fig. 3 veranschaulicht ein Anwendungsbeispiel eines Polstermaterialteils in Form eines Autositzteils 17, wobei in das üblicherweise aus Schaumstoff bestehende Polstermaterial 16 Formausnehmungen 18 und 19 in einer Längsreihenanordnung entsprechend dem gewünschten Blindnahtverlauf eingebracht sind. Die Formausnehmungen 18 und 19 besitzen die Form von auf der Rückseite 20 des Autositzteils 17 offen ausmündenden Sacklöchern einer Querschnittsform entsprechend der Flächengestalt der Haltelaschen 9. Die Formausnehmungen 18 weisen eine untereinander ungleiche Tiefe auf, derart, daß ihre Grundflächen 21, ungeachtet einer variierenden Polstermaterialdicke über den Blindnahtverlauf, den gleichen Abstand zur Oberseite des Autositzteils 17 mit dem Bezugstoff 14 aufweisen, der dem Längenmaß der Annähfahne 5 zwischen der Naht 15 und den Haltelaschen 9 entspricht. Die Formausnehmungen 19 besitzen, bei gleicher Polstermaterialdicke über den Blindnahtverlauf, untereinander die gleiche Tiefe. In den Grundflächen 21 der Formausnehmungen 18 und 19 befindet sich jeweils ein entsprechend dem vorgesehenen Blindnahtverlauf ausgerichteter Durchsteckschlitz 22, durch die die Haltelaschen 9 des Einzugstabs 1, mit an der Annähfahne 5 angelegter Halteleiste 6, hindurchgestreckt werden, um im verarbeiteten, von der Annähfahne 5 abgeklappten und mit dein Bezugstoff 14 an der Oberseite des Sitzteils 17 vernähten Zustand mit ihren seitlichen Halteleisten 6 und 7 an der Grundfläche 21 der Formausnehmungen 18 bzw. 19 des Polstermaterials 16 anzuliegen. Die Annähfahne 5 füllt dann den jeweiligen Durchsteckschlitz 22 aus.3 illustrates an example of an application of a cushion material part in the form of a car seat part 17, wherein shaped recesses 18 and 19 are made in the cushion material, which is usually made of foam, in a longitudinal row arrangement in accordance with the desired blind seam course. The shaped recesses 18 and 19 are in the form of blind holes with a cross-sectional shape that open out on the rear side 20 of the car seat part 17 and correspond to the shape of the surface of the holding tabs 9. The shaped recesses 18 have an unequal depth, such that their base surfaces 21 have a thickness regardless of a varying upholstery material the blind seam course, the same distance from the top of the car seat part 17 with the cover fabric 14, which corresponds to the length of the sewing flag 5 between the seam 15 and the retaining tabs 9. The shaped recesses 19 have, with the same cushioning material thickness over the blind seam course, the same depth among each other. In the base areas 21 of the shaped recesses 18 and 19 there is in each case a push-through slot 22 aligned according to the intended blind seam course, through which the holding tabs 9 of the pull-in bar 1, with the holding strip 6 attached to the sewing-on tab 5, are extended, in order to be processed by the sewing-on tab 5 folded and sewn with the cover fabric 14 on the top of the seat part 17 state with their lateral retaining strips 6 and 7 to rest on the base 21 of the mold recesses 18 and 19 of the cushioning material 16. The sew-on flag 5 then fills the respective push-through slot 22.

Die Haltelaschen 9 bewirken auf diese Weise in den Formausnehmungen 18 und 19 des Sitzteils 17 nach Art eines Ankers eine sichere Fixierung für den über die Annähfahne 5 eingezogenen, die Blindnaht ausbildenden streifenförmigen Bereich des oberseitigen Bezugstoffes 14. Den in Nahtlängsrichtung sauber konturierten verwindungsfreien Verlauf der Blindnaht gewährleistet hierbei der durchgehende Stützstab 11. Grundsätzlich ist auch eine Verarbeitung des Einzugstabs 1 ohne Formausnehmungen 18 oder 19 möglich, in welchem Fall die Haltelaschen 9 unmittelbar an der Rückseite 20 des Polstermaterialteils anliegen würden.In this way, the holding tabs 9 in the shaped recesses 18 and 19 of the seat part 17, in the manner of an anchor, provide a secure fixation for the strip-shaped area of the upper cover fabric 14 which is drawn in via the sewing tab 5 and forms the blind seam. The torsion-free course of the blind seam which is cleanly contoured in the longitudinal direction of the seam This is ensured by the continuous support rod 11.
