Abstract
Description
Die Erfindung betrifft ein Gurtband für einen Sicherheitsgurt eines Fahrzeuges, wobei das Gurtband parallel zur Längsausdehnung z-förmig gefaltet ist, wobei Faltlagen an Randbereichen mittels Aufreißfäden miteinander verbunden sind.The invention relates to a webbing for a safety belt of a vehicle, wherein the webbing is folded in a Z-shape parallel to the longitudinal extent, wherein folding layers are connected to each other at the edge regions by means of tear threads.
Aus der
Der Erfindung hegt die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Gurtband für einen Sicherheitsgurt eines Fahrzeuges anzugeben.The invention has the object to provide a comparison with the prior art improved webbing for a safety belt of a vehicle.
Die Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.The object is achieved by the features specified in
Ein Gurtband für einen Sicherheitsgurt eines Fahrzeuges ist parallel zur Längsausdehnung z-förmig gefaltet ist, wobei Faltlagen an Randbereichen mittels Aufreißfäden miteinander verbunden sind. Ein Aufreißfaden an jeweils einem Randbereich bildet eine Aufreißnaht. Erfindungsgemäß weisen die Aufreißfäden in den Randbereichen jeweils abschnittsweise unterschiedliche Nahtstärken auf. Dadurch sind an jedem Randbereich Abschnitte gebildet, wobei jedem Abschnitt eine Aufreißnaht einer bestimmten Nahtstärke zugeordnet ist.A webbing for a safety belt of a vehicle is folded in a Z-shaped parallel to the longitudinal extent, wherein folding layers are connected to each other at the edge regions by means of tear threads. A tear thread on each edge forms a tear seam. According to the invention, the tear-open threads each have different seam thicknesses in sections in the edge regions. As a result, sections are formed at each edge region, wherein each section is associated with a tear seam of a specific seam thickness.
Die Nahtstärke der Aufreißnaht ist durch den Abstand zwischen Einstichen der Aufreißfäden in das Gurtband bestimmt.The seam thickness of the tear seam is determined by the distance between punctures of the tear threads in the webbing.
Die Aufreißnähte dienen dazu, die Faltung des Gurtbandes zu fixieren, wobei die Aufreißnähte bei Befüllen eines Gurtinnenraumes des Gurtbandes mit einem Gas aufreißen. Somit ist eine Auflagefläche des Gurtbandes bei einer Kollision des Fahrzeuges durch Entfalten des Gurtbandes vergrößerbar. Dabei ist mittels der verschiedenen Nahtstärken in besonders vorteilhafter Weise zumindest eine Entfaltungsrichtung vorgebbar. Insbesondere ist vorgebbar, in welcher Reihenfolge die Abschnitte des Gurtbandes entfaltet werden sollen.The tear seams serve to fix the folding of the webbing, wherein the tear seams tear when filling a Gurtinnenraumes the webbing with a gas. Thus, a bearing surface of the webbing in a collision of the vehicle by unfolding of the webbing can be increased. In this case, at least one deployment direction can be predetermined in a particularly advantageous manner by means of the different seam thicknesses. In particular, it can be specified in which order the sections of the webbing are to be unfolded.
Dadurch, dass eine Entfaltung des Gurtbandes mittels der unterschiedlichen Nahtstärken vorgebbar ist und sich die Auflagefläche vergrößert, ist eine Belastung durch das Gurtband auf den Insassen bei einer Kollision des Fahrzeuges reduziert. Zudem ist ein Entfaltungs- und Positionierverhalten des Gurtbandes für einen Insassen verbessert, da ein Gurtrollverhalten mittels des erfindungsgemäßen Gurtbandes reduziert ist.Characterized in that a deployment of the webbing by means of the different seam thicknesses can be predetermined and the support surface increases, a load is reduced by the webbing on the occupant in a collision of the vehicle. In addition, a deployment and positioning behavior of the webbing is improved for an occupant, since a Gurtrollverhalten is reduced by means of the webbing according to the invention.
Dabei ist beispielsweise die Aufreißnaht, welche eine hohe Nahtstärke aufweist, in Richtung eines Gasgenerators zum Befüllen des Gurtinnenraumes angeordnet, so dass sich das Gurtband von einem dem Gasgenerator abgewandten Ende zu dem Gasgenerator hin entfaltet.In this case, for example, the tear seam, which has a high seam thickness, arranged in the direction of a gas generator for filling the Gurtinnenraumes, so that the webbing unfolds from an end facing away from the gas generator to the gas generator.
Besonders bevorzugt wird zuerst ein Abschnitt entfaltet, an dem ein besonders hohes Verletzungsrisiko für den Fahrzeuginsassen besteht.Particularly preferably, first a section is unfolded on which there is a particularly high risk of injury to the vehicle occupant.
Ein Ausführungsbeispiel der Erfindung wird im Folgenden anhand einer Zeichnung näher erläutert.An embodiment of the invention will be explained in more detail below with reference to a drawing.
