Definitions
- the invention relates to a seat belt webbing with the features of the preamble of claim 1 and a method for producing the same.
- Seat belts are e.g. Used in motor vehicles, aircraft and other mobile devices for restraining the occupants. To fulfill their task, the seat belts must have a given tensile strength. Furthermore, the seat belts should generally have a low-friction surface and a soft edge, so that the occupant as little as possible obstructed by the seat belt and the clothing of the occupant is not damaged.
- the seat belt webbing has a plurality of longitudinally extending warp threads interconnected by a weft yarn extending transversely of the warp yarns.
- the weft thread is shot during weaving by means of a weft needle from one side of the webbing between the warp threads and caught on the other side by means of a fishing thread, so that the weft yarn is not retracted when retracting the weft needle.
- the warp threads are in the load case of the seat belt webbing during an accident, the load-bearing threads and therefore must have a certain tensile strength, while the weft thread is less loaded and essentially forms the surface of the webbing. Accordingly, the weft should have better surface properties than the warp threads, but can in the For the sake of a softer surface have a lower tensile strength than the warp threads.
- a webbing which has in the edge regions warp threads with a different shrinkage characteristic than the warp threads in the central region.
- the weft thread is interwoven in the successive shots with a different number of warp threads, so that in the edge region certain warp threads, eg only every fourth or fifth weft, are covered by the weft thread.
- After weaving the webbing this is subjected to a heat treatment, wherein a soft edge is formed by the deliberate different shrinkage of the warp threads in the edge region.
- seat belt webbing are known, see for example US-A-4,600,626 in which the warp threads in the edge region are formed substantially finer than the warp threads in the middle region. Due to the finer warp threads in the edge region, the edge of the seat belt webbing is softer and the surface of the seat belt webbing much more homogeneous, so that the sawing effect of the seat belt webbing when rubbing at the edge is much lower.
- the object of the invention is to provide a further developed seat belt webbing with a soft edge and a method for producing the same.
- the fishing thread is arranged between the warp threads and covered by the weft thread and / or the warp threads to the surface of the seat belt webbing.
- the fishing thread itself has the task in the seat belt webbing to hold the weft thread during weaving in the reversal points, so it must have a certain tensile strength, so that it does not break during the weaving process and the weaving process must then be interrupted. It has surprisingly been found that the hardness of the edge is decisively influenced by the catching thread coming to the surface.
- the catching yarn differs in its properties from those of the weft thread owing to its function, so that the surface becomes inhomogeneous due to the catching thread coming to the surface between the weft threads, and the sawing effect of the edge during rubbing against e.g. the clothing of the occupant is increased.
- the surface of the edge is now determined solely by the weft and / or by the warp threads, since the fishing thread is disposed between the warp threads and is covered by the weft threads and / or the warp threads.
- the fishing thread is thus no longer visible from the outside.
- Another advantage resulting from the invention is that both edges of the seat belt webbing are thereby almost identical, even if a weaving technique is used in which a fishing thread is provided on only one side, and the weft thread is fed from one side only.
- a safety belt according to the invention can be seen with a fishing thread arranged between the warp threads.
- the seat belt webbing can be subdivided into a central region A and a peripheral region B.
- warp yarns 1 are provided which have a yarn thickness of 900 to 2100 dtex and as multifilaments with non-twisted filaments or twisted filaments with up to 150 revolutions per meter Length are formed.
- the warp threads 1 have the task to absorb the tensile forces acting during the accident and are therefore particularly strong and therefore also relatively stiff.
- finer warp threads 3 are provided with a yarn thickness of 400 to 1100 dtex, which are also formed as multifilaments with eg 28 filaments.
- the filaments are additionally twisted together up to 150 times per meter in length.
- a weft thread 2 is provided, which is shot during weaving of the webbing from one side with a weft needle through a shed, which is formed by two mutually standing layers of warp threads 1 and 3.
- the weft thread 2 is caught at one edge of the seat belt webbing by means of a fishing thread 5 and crocheted over a knitting needle with this.
- the weft yarn 2 is also formed as a multifilament with a yarn thickness of 280 to 1100 dtex, and has, for example, 96 filaments, which are twisted 130 times per meter in length. Due to the high number of filaments, the weft thread 2 is particularly mobile in itself, so that can be achieved with the weft a particularly soft and homogeneous surface of the seat belt webbing.
- the fishing thread 5 is also formed as a multifilament and has a yarn count of 280 dtex and 48 filaments with 80 revolutions per meter. Further, a blocking thread 4 is provided, which is guided together with the fishing thread 5 and causes a better cohesion of the fabric composite in the seat belt webbing.
- the finer warp threads 3 of the edge region B are woven into two wraps 6 and 7 with the weft yarn 2, wherein the weave pattern is formed such that alternately three warp threads 3 in a package III on one side of the weft thread 2 and a Warp thread 3 are passed on the other side in a package I of the weft yarn 2.
- the weft thread 2 is a single thread which is guided during the weaving process in a periodic reciprocating motion, thereby causing the cross-linking of the warp threads 1 and 3 and also forms at least a major part of the surface of the seat belt webbing.
- the weft thread 2 is guided past only the warp threads 3 and then pulls the catch thread 5 in the backward movement so far in the edge region B that he comes to lie in the finished woven seat belt webbing between the warp threads 3 and the surface of the weft yarn 2 is covered.
- the catching thread 5 is preferably drawn only as far as the edge area B up to the edge of the center area A between the finer warp threads 3, since the binding of the warp threads 1 to the weft thread 2 in the middle area A differs from the binding of the finer warp threads 3 the weft thread 2 in the edge region B is.
- the weft thread 2 is at the next shot at least by a part number of the warp threads 3, preferably shot through one of the layers 6 or 7, is then caught by the fishing thread 5 and pulls both the fishing thread 5 in the backward movement some of the warp threads 3 to the middle area A zoom.
- a soft edge with an inner fishing thread 5 whose surface is formed on the outside exclusively by the weft thread 2 and the finer warp threads 3.
- the tension in the fishing thread 5 should be selected so that the weft needle can retract the fishing thread 5 with the weft yarn 2, wherein the retraction or entrainment movement can be automatically limited by the different binding of the warp threads 1 and 3.
- the weave pattern in the present seat belt webbing is formed in the middle region A by two warp threads 1 combined in pairs, which are alternately passed by the weft thread 2 on different sides.
- the weave pattern and thus the binding of the warp threads 3 in the edge region B is formed by alternating groups I and III, which are each formed from three or a single warp thread 3 and are passed on different sides of the weft thread 2.
- groups I and III which are each formed from three or a single warp thread 3 and are passed on different sides of the weft thread 2.
- the proposed binding of the warp threads 3 in the edge region B has proven to be advantageous in that an edge can be obtained with a thickness which is substantially identical to the thickness of the seat belt webbing in the center region A.
- the proposed seat belt webbing offers the particular advantage that it has two at least almost identical soft edges and yet can be woven with only one weft thread 2 and a fishing thread 5 guided on one side. As a result, much higher working speeds can be achieved than is possible with straps with soft edges according to the prior art.
- the weave can be operated at about 1500-1600 rpm, whereby the manufacturing costs of the seat belt webbing are significantly lower than comparable safety belt webbing with soft edges.
- Another advantage resulting from the invention is that the fishing thread 5 is no longer associated with a particular group of warp threads 1 or 3, as is the case in the prior art.
- the fishing thread 5 loses its orientation and is intentionally arranged without a predetermined orientation between the warp threads 1 and 3, so that the seat belt webbing in the region of the edge has no more determined by the passing to the surface of the seat belt webbing catching thread 5 hardness distribution.

Description
Die Erfindung betrifft ein Sicherheitsgurtband mit den Merkmalen des Oberbegriffs des Anspruchs1 und ein Verfahren zur Herstellung desselben.The invention relates to a seat belt webbing with the features of the preamble of claim 1 and a method for producing the same.
Sicherheitsgurte werden z.B. in Kraftfahrzeugen, Flugzeugen und anderen mobilen Einrichtungen zur Rückhaltung der Insassen verwendet. Zur Erfüllung ihrer Aufgabe müssen die Sicherheitsgurte eine vorgegebene Zugfestigkeit aufweisen. Ferner sollten die Sicherheitsgurte im Allgemeinen eine möglichst reibungsarme Oberfläche und eine weiche Kante aufweisen, damit der Insasse durch den Sicherheitsgurt möglichst wenig behindert und die Kleidung des Insassen nicht beschädigt wird.Seat belts are e.g. Used in motor vehicles, aircraft and other mobile devices for restraining the occupants. To fulfill their task, the seat belts must have a given tensile strength. Furthermore, the seat belts should generally have a low-friction surface and a soft edge, so that the occupant as little as possible obstructed by the seat belt and the clothing of the occupant is not damaged.
Das Sicherheitsgurtband weist eine Vielzahl von in Längsrichtung verlaufenden Kettfäden auf, welche durch einen quer zu den Kettfäden verlaufenden Schussfaden miteinander verbunden sind. Der Schussfaden wird beim Weben mittels einer Schussnadel von einer Seite des Gurtbandes zwischen die Kettfäden hindurch geschossen und auf der anderen Seite mittels eines Fangfadens gefangen, so dass der Schussfaden beim Zurückziehen der Schussnadel nicht mit zurückgezogen wird. Die Kettfäden sind im Belastungsfall des Sicherheitsgurtbandes während eines Unfalls die Last tragenden Fäden und müssen deshalb eine gewisse Zugfestigkeit aufweisen, während der Schussfaden weniger belastet ist und im Wesentlichen die Oberfläche des Gurtbandes bildet. Demnach sollte der Schussfaden bessere Oberflächeneigenschaften als die Kettfäden aufweisen, kann dafür aber im Sinne einer weicheren Oberfläche eine geringere Zugfestigkeit als die Kettfäden aufweisen.The seat belt webbing has a plurality of longitudinally extending warp threads interconnected by a weft yarn extending transversely of the warp yarns. The weft thread is shot during weaving by means of a weft needle from one side of the webbing between the warp threads and caught on the other side by means of a fishing thread, so that the weft yarn is not retracted when retracting the weft needle. The warp threads are in the load case of the seat belt webbing during an accident, the load-bearing threads and therefore must have a certain tensile strength, while the weft thread is less loaded and essentially forms the surface of the webbing.

Aufgabe der Erfindung ist es, ein weiterentwickeltes Sicherheitsgurtband mit einer weichen Kante und ein Verfahren zur Herstellung desselben zu schaffen.The object of the invention is to provide a further developed seat belt webbing with a soft edge and a method for producing the same.
Zur Lösung der Aufgabe wird erfindungsgemäß ein Sicherheitsgurtband mit den Merkmalen des Anspruchs 1 und ein Verfahren mit den Merkmalen des Anspruchs 5 vorgeschlagen.To achieve the object, a seat belt webbing according to the invention with the features of claim 1 and a method with the features of
Weitere bevorzugte Ausführungsformen der Erfindung sind den Unteransprüchen, der Figur sowie der zugehörigen Beschreibung zu entnehmen.Further preferred embodiments of the invention are the subclaims, the figure and the associated description refer to.
Erfindungsgemäß ist der Fangfaden zwischen den Kettfäden angeordnet und zur Oberfläche des Sicherheitsgurtbandes durch den Schussfaden und/oder die Kettfäden abgedeckt.According to the invention, the fishing thread is arranged between the warp threads and covered by the weft thread and / or the warp threads to the surface of the seat belt webbing.
Der Fangfaden selbst hat in dem Sicherheitsgurtband die Aufgabe, den Schussfaden beim Weben in den Umkehrstellen festzuhalten, deshalb muss er eine bestimmte Zugfestigkeit aufweisen, damit er während des Webvorganges nicht reißt und der Webvorgang daraufhin unterbrochen werden muss. Es hat sich erstaunlicherweise herausgestellt, dass die Härte der Kante entscheidend durch den an die Oberfläche tretenden Fangfaden mit beeinflusst wird. Der Fangfaden unterscheidet sich aufgrund seiner Funktion in seinen Eigenschaften von denen des Schussfadens, so dass die Oberfläche durch den zwischen den Schussfäden an die Oberfläche tretenden Fangfaden inhomogen wird, und der Sägeeffekt der Kante beim Reiben an z.B. der Kleidung des Insassen vergrößert wird. Durch die erfindungsgemäße Lösung ist die Oberfläche der Kante nunmehr allein durch den Schussfaden und/oder durch die Kettfäden bestimmt, da der Fangfaden zwischen den Kettfäden angeordnet ist und durch die Schussfäden und/oder die Kettfäden abgedeckt ist. Der Fangfaden ist dadurch von außen nicht mehr zu erkennen. Ein weiterer sich aus der Erfindung ergebender Vorteil ist, dass beide Ränder des Sicherheitsgurtbandes dadurch nahezu identisch sind, auch wenn eine Webtechnik verwendet wird, bei der nur an einer Seite ein Fangfaden vorgesehen ist, und der Schussfaden nur von einer Seite zugeführt wird.The fishing thread itself has the task in the seat belt webbing to hold the weft thread during weaving in the reversal points, so it must have a certain tensile strength, so that it does not break during the weaving process and the weaving process must then be interrupted. It has surprisingly been found that the hardness of the edge is decisively influenced by the catching thread coming to the surface. The catching yarn differs in its properties from those of the weft thread owing to its function, so that the surface becomes inhomogeneous due to the catching thread coming to the surface between the weft threads, and the sawing effect of the edge during rubbing against e.g. the clothing of the occupant is increased. The inventive solution, the surface of the edge is now determined solely by the weft and / or by the warp threads, since the fishing thread is disposed between the warp threads and is covered by the weft threads and / or the warp threads. The fishing thread is thus no longer visible from the outside. Another advantage resulting from the invention is that both edges of the seat belt webbing are thereby almost identical, even if a weaving technique is used in which a fishing thread is provided on only one side, and the weft thread is fed from one side only.
Ungleiche Seiten des Sicherheitsgurtes haben im Allgemeinen den Nachteil, dass sie sich unterschiedlich abnutzen und das Sicherheitsgurtband dadurch nach einem längeren Tragen optisch einen geringwertigeren Eindruck auf den Betrachter macht. Ferner können die ungleichen Kanten bei einem Einbau mit einer falschen Orientierung in dem Gurtaufroller zu einer unerwünschten Geräuschbildung bei der Ein- und Auszugsbewegung des Sicherheitsgurtbandes führen. Aus diesem Grunde müssen bei dem Einbau des Gurtbandes in den Gurtaufroller besondere Kosten verursachende Maßnahmen getroffen werden, um eine fehlerhafte Montage mit einer falschen Ausrichtung des Sicherheitsgurtbandes zu verhindern. Ferner führen ungleiche Kanten dazu, dass das Sicherheitsgurtband beim Durchzug durch den Umlenker zusätzliche Geräusche verursacht, die Ein- und Auszugskräfte des Sicherheitsgurtbandes sich nachteilig verändern und die Gurtauflagefläche des Umlenkers ungleich abgenutzt wird.Unequal sides of the seat belt generally have the disadvantage that they wear differently and that Seat belt strap makes it optically a lesser-valued impression on the viewer after prolonged wear. Further, the uneven edges may result in an installation with a wrong orientation in the belt retractor to an undesirable noise during the retraction and extension movement of the seat belt webbing. For this reason, in the installation of the webbing in the belt retractor special cost-causing measures must be taken to prevent incorrect assembly with a wrong orientation of the seat belt webbing. Furthermore, uneven edges cause the seat belt webbing causes additional noise when passing through the deflector, the retraction and withdrawal forces of the seat belt webbing adversely affect and the Gurtauflagefläche the deflector is unevenly worn.
Nachfolgend wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels näher erläutert. In der einzigen Figur ist ein erfindungsgemäßer Sicherheitsgurt mit einem zwischen den Kettfäden angeordneten Fangfaden zu erkennen.The invention will be explained in more detail with reference to a preferred embodiment. In the single figure, a safety belt according to the invention can be seen with a fishing thread arranged between the warp threads.
Das Sicherheitsgurtband kann unterteilt werden in einen Mittenbereich A und einen Randbereich B. In dem Mittenbereich A sind Kettfäden 1 vorgesehen, welche eine Garnstärke von 900 bis 2100 dtex aufweisen und als Multifilamente mit nicht verdrehten Filamenten oder mit gedrehten Filamenten mit bis zu 150 Umdrehungen pro Meter Länge ausgebildet sind. Die Kettfäden 1 haben die Aufgabe, die während des Unfalles wirkenden Zugkräfte aufzunehmen und sind deshalb besonders fest und demnach auch verhältnismäßig steif. In dem Randbereich B sind feinere Kettfäden 3 mit einer Garnstärke von 400 bis 1100 dtex vorgesehen, welche ebenfalls als Multifilamente mit z.B. 28 Filamenten ausgebildet sind. Die Filamente sind zusätzlich bis zu 150 mal pro Meter Länge miteinander verdreht.The seat belt webbing can be subdivided into a central region A and a peripheral region B. In the middle region A, warp yarns 1 are provided which have a yarn thickness of 900 to 2100 dtex and as multifilaments with non-twisted filaments or twisted filaments with up to 150 revolutions per meter Length are formed. The warp threads 1 have the task to absorb the tensile forces acting during the accident and are therefore particularly strong and therefore also relatively stiff. In the edge region B finer warp threads 3 are provided with a yarn thickness of 400 to 1100 dtex, which are also formed as multifilaments with eg 28 filaments. The filaments are additionally twisted together up to 150 times per meter in length.
Ferner ist ein Schussfaden 2 vorgesehen, der beim Weben des Gurtbandes von einer Seite mit einer Schussnadel durch ein Webfach geschossen wird, welches durch zwei winklig zueinander stehende Lagen von Kettfäden 1 und 3 gebildet ist. Der Schussfaden 2 wird an einem Rand des Sicherheitsgurtbandes mittels eines Fangfadens 5 gefangen und über eine Wirknadel mit diesem verhäkelt. Der Schussfaden 2 ist ebenfalls als Multifilament mit einer Garnstärke von 280 bis 1100 dtex ausgebildet, und weist beispielsweise 96 Filamente auf, die 130 Mal pro Meter Länge miteinander verdreht sind. Aufgrund der hohen Anzahl der Filamente ist der Schussfaden 2 in sich besonders beweglich, so dass sich mit dem Schussfaden eine besonders weiche und homogene Oberfläche des Sicherheitsgurtbandes erzielen lässt. Der Fangfaden 5 ist ebenfalls als Multifilament ausgebildet und weist eine Garnstärke von 280 dtex und 48 Filamenten mit 80 Umdrehungen pro Meter auf. Ferner ist ein Sperrfaden 4 vorgesehen, der zusammen mit dem Fangfaden 5 geführt wird und in dem Sicherheitsgurtband einen besseren Zusammenhalt des Gewebeverbundes bewirkt.Further, a
Wie in der
Bei jedem zweiten Schuss wird der Schussfaden 2 lediglich an den Kettfäden 3 vorbeigeführt und zieht den Fangfaden 5 anschließend bei der Rückwärtsbewegung so weit in den Randbereich B hinein, dass er bei dem fertig gewebten Sicherheitsgurtband zwischen den Kettfäden 3 zu liegen kommt und zur Oberfläche hin von dem Schussfaden 2 abgedeckt ist. Dabei wird der Fangfaden 5 vorzugsweise nur bis in den Randbereich B bis maximal an den Rand des Mittenbereichs A zwischen die feineren Kettfäden 3 gezogen, da die Bindung der Kettfäden 1 an den Schussfaden 2 in dem Mittenbereich A unterschiedlich zu der Bindung der feineren Kettfäden 3 zu dem Schussfaden 2 in dem Randbereich B ist. Nach diesem Schuss des Schussfadens 2 wird der Schussfaden 2 bei dem nächsten Schuss zumindest durch eine Teilanzahl der Kettfäden 3, vorzugsweise durch eine der Lagen 6 oder 7 hindurch geschossen, wird dann von dem Fangfaden 5 gefangen und zieht bei der Rückwärtsbewegung sowohl den Fangfaden 5 als auch einige der Kettfäden 3 an den Mittenbereich A heran. Insgesamt entsteht an dem Rand des Mittenbereichs A auf diese Art eine weiche Kante mit einem innen liegenden Fangfaden 5, deren Oberfläche an der Außenseite ausschließlich durch den Schussfaden 2 und die feineren Kettfäden 3 gebildet ist. Damit ergibt sich eine identische Oberflächenstruktur der Ränder des Sicherheitsgurtbandes, auch wenn der Schussfaden 2 nur an einer Seite von einem Fangfaden 5 gefangen wird, da der Fangfaden 5 eben zwischen den feineren Kettfäden 3 angeordnet und zur Oberfläche allseitig von dem Schussfaden 2 abgedeckt ist, und dadurch nicht an die Oberfläche tritt.In each second shot, the
Insbesondere sollte die Zugspannung in dem Fangfaden 5 so gewählt werden, dass die Schussnadel den Fangfaden 5 mit dem Schussfaden 2 zurückziehen kann, wobei die Einzieh- oder Mitnahmebewegung automatisch durch die unterschiedliche Bindung der Kettfäden 1 und 3 begrenzt werden kann. Unter der Bindung der Kettfäden 1 und 3 wird das Webmuster, gebildet durch den hindurch geschossenen Schussfaden 2 und die dabei einzeln oder in Gruppen miteinander bewegten Kettfäden 1 und 3, verstanden. Das Webmuster in dem vorliegenden Sicherheitsgurtband ist in dem Mittenbereich A durch jeweils zwei paarweise zusammengefasste Kettfäden 1 gebildet, die abwechselnd von dem Schussfaden 2 an unterschiedlichen Seiten passiert werden. Das Webmuster und damit die Bindung der Kettfäden 3 in dem Randbereich B ist durch sich abwechselnde Gruppen I und III gebildet, welche jeweils aus drei oder einem einzelnen Kettfaden 3 gebildet sind und auf unterschiedlichen Seiten von dem Schussfaden 2 passiert werden. Auf die Bewegung der Kettfäden 1 und 3 zwischen den einzelnen Schüssen des Schussfadens 2 wird hier nicht näher eingegangen. In Kenntnis der geläufigen Webtechnik kann diese aber sehr leicht hergeleitet werden.In particular, the tension in the
Die vorgeschlagene Bindung der Kettfäden 3 in dem Randbereich B hat sich insofern vorteilhaft herausgestellt, da sich dadurch eine Kante mit einer Dicke erzielen lässt, welche im Wesentlichen identisch zu der Dicke des Sicherheitsgurtbandes in dem Mittenbereich A ist.The proposed binding of the warp threads 3 in the edge region B has proven to be advantageous in that an edge can be obtained with a thickness which is substantially identical to the thickness of the seat belt webbing in the center region A.
Das vorgeschlagene Sicherheitsgurtband bietet insbesondere den Vorteil, dass es zwei wenigstens nahezu identische weiche Kanten aufweist und dennoch mit nur einem Schussfaden 2 und einem einseitig geführten Fangfaden 5 gewebt werden kann. Dadurch können wesentlich höhere Arbeitsgeschwindigkeiten erzielt werden, als dies bei Gurtbändern mit weichen Kanten nach dem Stand der Technik möglich ist. Der Webstock kann dabei mit ca. 1500 - 1600 U/min betrieben werden, wodurch die Herstellkosten des Sicherheitsgurtbandes deutlich niedriger sind als vergleichbare Sicherheitsgurtbänder mit weichen Kanten.The proposed seat belt webbing offers the particular advantage that it has two at least almost identical soft edges and yet can be woven with only one
Ein weiterer sich aus der Erfindung ergebender Vorteil ist der, dass der Fangfaden 5 nicht mehr einer bestimmten Gruppe von Kettfäden 1 oder 3 zugeordnet ist, wie dies beim Stand der Technik der Fall ist. Der Fangfaden 5 verliert seine Orientierung und ist bewusst ohne eine vorgegebene Orientierung zwischen den Kettfäden 1 und 3 angeordnet, so dass das Sicherheitsgurtband im Bereich der Kante keine durch den an die Oberfläche des Sicherheitsgurtbandes tretenden Fangfaden 5 bestimmte Härteverteilung mehr aufweist.Another advantage resulting from the invention is that the
