Abstract
Description
Die Erfindung betrifft einen aufblasbaren Sicherheitsgurt mit den Merkmalen des Oberbegriffs von Anspruch 1 und einen Gurtknopf für einen aufblasbaren Sicherheitsgurt mit den Merkmalen des Oberbegriffs von Anspruch 11.The invention relates to an inflatable safety belt with the features of the preamble of claim 1 and a belt button for an inflatable seat belt with the features of the preamble of
Aufblasbare Sicherheitsgurte werden im Unfall zu einer dicken „Wurst” aufgeblasen, wodurch die Insassenbelastung weiter gesenkt und eventuell vorhandene Gurtlose aus dem Sicherheitsgurt herausgezogen werden können. Dazu ist der Sicherheitsgurt mehrlagig mit mehreren aneinander anliegenden Gurtbandlagen ausgebildet und mit einer Druckgasquelle verbunden, welche bei einer Aktivierung einen Gasstrom zwischen die Gurtbandlagen einleitet und den Sicherheitsgurt durch Vergrößerung des zwischen den Gurtbandlagen vorhandenen Hohlraums zu der dicken „Wurst” aufbläst.Inflatable seat belts are inflated in the accident to a thick "sausage", whereby the occupant load can be further reduced and any existing slack can be pulled out of the seat belt. For this purpose, the safety belt is multi-layered with a plurality of adjoining Gurtbandlagen and connected to a compressed gas source which initiates a gas flow between the Gurtbandlagen upon activation and inflates the seat belt by increasing the existing between the Gurtbandlagen cavity to the thick "sausage".
Ferner sind Sicherheitsgurte im Allgemeinen mit einem an einer vorbestimmten Stelle des Sicherheitsgurtes positionierten Gurtknopf versehen, welcher sicherstellt, dass die an dem Sicherheitsgurt verschieblich geführte Gurtzunge in der Parkposition des Sicherheitsgurtes in einer für den Nutzer griffgünstigen Höhe hängt. Der Gurtknopf selbst ist durch ein erstes Klemmteil mit einem Stift und einem tellerförmigen Kopf gebildet, welches mit dem Stift durch das Gurtband gestoßen wird und anschließend durch eine Verbindung mit einem zweiten Klemmteil an dem Sicherheitsgurt festgeklemmt und gegen Herausrutschen gesichert wird. Das erste und zweite Klemmelement sind dabei bevorzugt durch eine kostengünstige und einfach zu handhabende Clipsverbindung miteinander verbunden. Der Gurtknopf selbst hat außer der Funktion, die Gurtzunge in der Parkposition des Sicherheitsgurtes in einer bestimmten Höhe zu halten, keine Funktion und ist deshalb als kostengünstiges Kunststoffteil ausgeführt.Furthermore, safety belts are generally provided with a belt button positioned at a predetermined point of the seat belt, which ensures that the belt tongue displaceably guided on the safety belt hangs in the parking position of the safety belt at a height that is convenient for the user. The belt button itself is formed by a first clamping member with a pin and a plate-shaped head, which is pushed by the pin through the webbing and then clamped by a connection with a second clamping member to the seat belt and secured against slipping out. The first and second clamping element are preferably connected to each other by a cost-effective and easy-to-use clip connection. The belt button itself has in addition to the function of holding the belt tongue in the parked position of the seat belt at a certain height, no function and is therefore designed as a low-cost plastic part.
Ein sich bei aufblasbaren Sicherheitsgurten grundlegendes Problem ist es dabei, dass der Aufblasvorgang des aufblasbaren Sicherheitsgurtes durch den Gurtknopf so wenig wie möglich gestört werden sollte.An underlying problem with inflatable seat belts is that the inflating operation of the inflatable seat belt should be disturbed as little as possible by the belt button.
Aus der
Da der aufblasbare Sicherheitsgurt beim Aufblasen mit einem unter einem erheblichen Druck stehenden Gasstrom beaufschlagt wird, werden die Gurtbandlagen während des Aufblasens mit einer entsprechend hohen Kraft verformt. Aufgrund der durch die hohen Kräfte bewirkten Verformung besteht dabei grundsätzlich das Problem, dass die Befestigung des Gurtknopfes mit einer herkömmlichen Clipsverbindung nicht ausreichend ist und sich der Gurtknopf beim Aufblasen des Sicherheitsgurtes von diesem löst.Since the inflatable seat belt is subjected to inflation under a considerable pressure gas flow, the Gurtbandlagen be deformed during inflation with a correspondingly high force. Due to the deformation caused by the high forces there is basically the problem that the attachment of the belt button with a conventional clip connection is not sufficient and the belt button dissolves when inflating the seat belt of this.
Aufgabe der Erfindung ist es daher, einen aufblasbaren Sicherheitsgurt mit einem Gurtknopf zu schaffen, bei dem der Gurtknopf auch beim Aufblasen des Sicherheitsgurtes sicher an dem Sicherheitsgurt gehalten ist.The object of the invention is therefore to provide an inflatable safety belt with a belt button, wherein the belt button is held securely on the seat belt even when inflating the seat belt.
Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, dass der Gurtknopf wenigstens zweiteilig mit einem ersten und einem zweiten Klemmteil ausgebildet ist, welche an verschiedenen Seiten der Gurtbandlage angeordnet sind, und dass an dem ersten Klemmteil ein Stift vorgesehen ist, mit dem das erste Klemmteil die Gurtbandlage durchstößt, und dass zur Verbindung der Klemmteile ein Sicherungselement vorgesehen ist, welches den durch die Gurtbandlage ragenden Stift quer zur Längserstreckung des Sicherheitsgurtes mit dem zweiten Klemmteil verbindet.To achieve the object, the present invention proposes that the belt button is formed at least in two parts with a first and a second clamping part, which are arranged on different sides of the Gurtbandlage, and that on the first clamping part a pin is provided, with which the first clamping part the Gurtbandlage pierces, and that for connecting the clamping parts, a securing element is provided which connects the protruding through the webbing position pin transversely to the longitudinal extent of the safety belt with the second clamping part.
Der Vorteil der Erfindung ist darin zu sehen, dass die Verbindung der Klemmteile durch ein gesondertes Sicherungselement verwirklicht ist, so dass die Verbindung der Klemmteile an sich schon stabiler ausgeführt werden kann. Außerdem verbindet das Sicherungselement die Klemmteile quer zur Längserstreckung des Sicherheitsgurtes, so dass die Verbindung der Klemmteile genau in die Richtung versteift wird, in die die Verbindung der Klemmteile beim Aufblasen des Sicherheitsgurtes durch die Verformung der Gurtbandlagen belastet wird. Dadurch kann die Wahrscheinlichkeit, dass sich der Gurtknopf insgesamt oder eines der Klemmteile beim Aufblasen des Sicherheitsgurtes von diesem löst, erheblich verringert werden.The advantage of the invention is to be seen in the fact that the connection of the clamping parts is realized by a separate fuse element, so that the connection of the clamping parts can already be made more stable per se. In addition, the securing element connects the clamping parts transversely to the longitudinal extent of the safety belt, so that the connection of the clamping parts is stiffened exactly in the direction in which the connection of the clamping parts is loaded during the inflation of the seat belt by the deformation of the Gurtbandlagen. As a result, the likelihood that the belt button as a whole or one of the clamping parts dissolves when the seat belt is inflated can be considerably reduced.
