Abstract
Description
Die vorliegende Erfindung betrifft eine Reißnahtausbildung im Bezug eines mit einem Airbag ausgerüsteten Kraftfahrzeugsitzes.The The present invention relates to a tear seam formation in relation to a equipped with an airbag Motor vehicle seat.
In Kraftfahrzeugsitze integrierte Airbags gehören heute fast schon zur Standardausrüstung von Kraftfahrzeugen. In aller Regel sind die Airbags in die Rückenlehne des Fahrzeugsitzes eingebaut, wobei dafür Sorge zu tragen ist, dass sich der Airbag im Bedarfsfall ungehindert aus der Rückenlehne heraus in die gewünschte Richtung entfalten kann. Dazu ist eine entsprechende Austrittsöffnung für den Airbag in der Rückenlehne erforderlich, die den ästhetischen Gesamteindruck des Sitzes stört. Es gibt daher verschiedene Lösungen, deren Ziel es ist, Optik und Funktionalität verträglich miteinander zu verbinden.In Airbags integrated into motor vehicle seats are now almost standard equipment for motor vehicles. The airbags are usually in the backrest of the vehicle seat built in, for that Care must be taken to ensure that the airbag is not obstructed if necessary from the backrest out into the desired one Direction can unfold. There is a corresponding outlet opening for the airbag in the backrest required the overall aesthetic impression of the seat. So there are different solutions the aim of which is to combine optics and functionality in a compatible manner.
Eine
häufig
zu findende Lösung,
zu der auch die vorliegende Erfindung gehört, besteht darin, den Austritt
mit dem Bezug der Polsterung zu überziehen (
Aufgabe der vorliegenden Erfindung ist es, eine Reißnahtausbildung mit sich kreuzenden, Bezugsteile miteinander verbindenden Reißnähten zur Verfügung zu stellen, bei der im Kreuzungsbereich der Nähte zu setzende Nahtriegel keine örtliche Steigerung der Nahtfestigkeit hervorrufen.task The present invention is to provide a tear seam formation with intersecting, Covering parts connecting tear seams are available the seam bar to be set in the area where the seams cross no local Increase the seam strength.
Diese Aufgabe wird dadurch gelöst, dass die Nahtriegel im Kreuzungsbereich der Reißnähte jeweils nur in einem der beteiligten Bezugsteile gesetzt sind. Erfindungsgmäß durchsetzt der Nahtriegel also im Kreuzungsbereich der Reißnähte nicht beide zu verbindenden Bezugsteile, sondern nur eines der Bezugsteile, wodurch eine örtliche Steigerung der Festigkeit der Reißnaht vermieden wird. Damit ist ein Aufreißen der Reißnähte auch im funktionswichtigen Kreuzungsbereich gewährleistet.This Task is solved by that the seam tack in the crossing area of the tear seams only in one of the involved reference parts are set. Enforced according to the invention the seam bar therefore not both to be connected in the area of intersection of the tear seams Reference parts, but only one of the reference parts, creating a local Increasing the strength of the tear seam is avoided. In order to is tearing open the seams too guaranteed in the functionally important intersection area.
Unter
sich kreuzenden Reißnähten sind
im Sinne der vorliegenden Erfindung Reißnähte zu verstehen, die, wie
in den
In einer vorteilhafter Ausgestaltung der Erfindung sind die Nahtriegel in einem Überstand eines der Bezugsteile gegenüber dem anderen Bezugsteil gesetzt. Durch diese Anordnung lässt sich der Nahtriegel nähtechnisch auf einfache Weise setzen. Nachteilig ist, dass durch den Überstand, wenngleich dieser auch sehr klein sein kann, sich der Verbrauch an Bezugsmaterial erhöht.In An advantageous embodiment of the invention are the seams in a supernatant one of the reference parts opposite the other reference part. This arrangement allows the seam bartack technically put in a simple way. The disadvantage is that due to the protrusion, although this can also be very small, the consumption itself Cover material increased.
Dieser Nachteil kann verringert werden, wenn anstelle des Überstandes eine Nahtriegelfahne vorgesehen ist.This Disadvantage can be reduced if instead of the supernatant a seam bar flag is provided.
Kein erhöhter Verbrauch an Bezugsmaterial ist bei einer weiteren Ausführungsform der vorliegenden Erfindung zu verzeichnen, bei der die beteiligten Bezugsteile im Kreuzungsbereich Rand an Rand liegen und die Reißnähte in einer von ihnen abgewinkelten Naht enden, die nur einen der Bezugsteile durchsetzt und den Nahtriegel aufweist. Allerdings ist diese Variante nähtechnisch etwas aufwendiger.No increased The consumption of reference material is in a further embodiment of the present invention in which the reference parts involved in the intersection area edge to edge and the tear seams in one ends of them angled seam that passes through only one of the reference parts and has the seam bartack. However, this variant is sewing technology somewhat more complex.
