Description

Die vorliegende Erfindung betrifft eine Gurtkraft-Meßanordnung, mit der sich auf einen Gurt, insbesondere einen Kraftfahrzeug-Sicherheitsgurt, wirkenden Kräfte messen lassen.The present invention relates to a belt force measuring arrangement with which a belt, in particular a motor vehicle seat belt, let forces measured.

Für Kraftfahrzeuge sind unterschiedliche Sicherheitsgurtsysteme bekannt. So wird beispielsweise in der DE 195 17 440 A1 der Anmelderin ein Sicherheitsgurtsystem vorgeschlagen, welches einen Gurtaufroller mit Kraftbegrenzung umfaßt, wobei zum Abbau von unfallbedingten Lastspitzen ein kraftbegrenzendes Deformationselement in den Kraftfluß von einer den Sicherheitsgurt aufnehmenden Wickeltrommel zum Gehäuse des Gurtaufrollers eingesetzt wird.Different seat belt systems are known for motor vehicles. So will for example in DE 195 17 440 A1 of the applicant a seat belt system proposed which includes a belt retractor with force limitation, being for dismantling a load-limiting deformation element in the power flow from load-related peak loads from a winding drum receiving the seat belt to the housing of the Belt retractor is used.

Für die Entwicklung derartiger Sicherheitsgurtsysteme sind genaue Kenntnisse über die während des normalen Fahrbetriebs sowie im Falle eines Unfalls auftretenden und auf den Sicherheitsgurt wirkenden Kräfte erforderlich. So sind bereits Kraftmeßanordnungen bekannt, welche in Crash-Versuchen die während eines Unfalls auf den Sicherheitsgurt wirkenden Kräfte erfassen können. Da während eines Unfalls erhebliche Zugkräfte auf den Sicherheitsgurt wirken, müssen diese Kraftmeßanordnungen einen Meßbereich < 10 kN aufweisen.For the development of such seat belt systems, exact knowledge of the during normal driving as well as in the event of an accident and on the Seat belt forces are required. So are force measuring arrangements Known in crash tests on the seat belt during an accident acting forces can capture. Because during an accident considerable tractive forces on the Seat belt act, these force measuring devices must have a measuring range <10 kN exhibit.

Diese bekannten Meßanordnungen sind jedoch nicht dazu geeignet, die während des normalen Fahrbetriebs auf den Sicherheitsgurt wirkenden Auszugs- oder Rückzugskräfte zu erfassen, da diese um mehrere Größenordnungen unterhalb der bei einem Unfall auftretenden Zugkräfte liegen. Zum Messen derartiger kleiner Kräfte, die während des normalen Fahrbetriebs auftreten, sind vielmehr Kraftmeßanordnungen mit einem Meßbereich < 20 N erforderlich.However, these known measuring arrangements are not suitable for the pulling or retracting forces acting on the seat belt during normal driving capture, since this is several orders of magnitude below that in the event of an accident occurring tensile forces. To measure such small forces that during the normal driving operation occur, are rather force measuring arrangements with a Measuring range <20 N required.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Gurtkraft-Meßanordnung bereitzustellen, welche einfach aufgebaut ist und eine zuverlässige Messung von relativ kleinen Kräften, die auf einen Gurt wirken können, ermöglicht. Insbesondere soll die Gurtkraft-Meßanordnung zum Einsatz in Kraftfahrzeugen für die Messung der während des normalen Fahrbetriebs auf den Sicherheitsgurt des Kraftfahrzeugs wirkenden Auszugs- und/oder Rückzugskräfte geeignet und mobil ausgestaltet sein. The present invention is therefore based on the object of a belt force measuring arrangement to provide, which is simple and a reliable measurement of relative small forces that can act on a belt. In particular, the Belt force measuring arrangement for use in motor vehicles for measuring during the normal driving operation on the seat belt of the motor vehicle pull-out and / or withdrawal forces can be suitable and designed to be mobile.  

Diese Aufgabe wird gemäß der vorliegenden Erfindung durch eine Gurtkraft-Meßanordnung mit den Merkmalen des Anspruches 1 gelöst. Die Unteransprüche definieren jeweils bevorzugte und vorteilhafte Ausführungsformen der vorliegenden Erfindung.This object is achieved according to the present invention by a belt force measuring arrangement solved with the features of claim 1. The subclaims define each preferred and advantageous embodiments of the present invention.

Die erfindungsgemäße Gurtkraft-Meßanordnung umfaßt einen Kraftmeßelement-Träger, auf dem ein Kraftmeßelement zum Erzeugen eines Meßsignals, welches einer auf den Gurt wirkenden Kraft entspricht, angebracht ist, Gurtaufnahmemittel, welche an zwei Seiten des Kraftmeßelement-Trägers angeordnet und mit diesem verbunden sind, um den Gurt an den zwei Seiten des Kraftmeßelement-Trägers aufzunehmen, sowie Gurtbefestigungsmittel, um den Gurt in den Gurtaufnahmemitteln zu fixieren.The belt force measuring arrangement according to the invention comprises a force measuring element carrier a force measuring element for generating a measuring signal, which one on the belt acting force corresponds, is attached, belt receiving means, which on two sides of the Force measuring element carrier are arranged and connected to the belt to the to accommodate two sides of the force measuring element carrier, as well as belt fastening means in order to fix the belt in the belt take-up devices.

Die Gurt-Kraftmeßanordnung, in der als Kraftmeßelement insbesondere ein Dehnungsmeßstreifen (DMS) mit einem Meßbereich < 20 N eingesetzt werden kann, ist derart ausgestaltet, daß sie von dem Gurt lösbar und beliebig an einer anderen Stelle plazierbar ist. Zu diesem Zweck können die Gurtbefestigungsmittel ösenförmig ausgestaltet sein, so daß der Gurt in Form einer Schleife in jeder der Ösen sowohl hinein- als auch herausgeführt wird. In jede Gurtschleife wird dann ein Fixierelement des Gurtbefestigungsmittels eingeführt, welche einen größeren Durchmesser als die Öffnung der entsprechenden Öse besitzt, so daß in jeder Öse eine zuverlässige Fixierung des Gurts möglich ist.The belt force measuring arrangement, in particular as a force measuring element Strain gauges (DMS) with a measuring range <20 N can be used designed in such a way that it can be detached from the belt and at any other point can be placed. For this purpose, the belt fastening means can be designed in the shape of a loop be so that the strap is looped in and out of each of the eyelets is brought out. In each belt loop a fixing element of the Belt fastener introduced, which has a larger diameter than the opening of the has appropriate eyelet, so that a reliable fixation of the belt in each eyelet is possible.

Die vorliegende Erfindung eignet sich insbesondere zum Einsatz in Kraftfahrzeugen, um ohne Beeinträchtigung des normalen Fahrbetriebs und ohne Umbau des Sicherheitsgurtsystems die während des normalen Fahrbetriebs auf den Sicherheitsgurt wirkenden Kräfte messen und erfassen zu können. Die vorliegende Erfindung ist jedoch selbstverständlich nicht auf diesen Anwendungsbereich beschränkt, sondern kann grundsätzlich auf allen Anwendungsgebieten eingesetzt werden, wo eine möglichst flexible und mobile Erfassung von relativ kleinen Gurtkräften erforderlich ist.The present invention is particularly suitable for use in motor vehicles without affecting normal driving and without converting the Seat belt system on the seat belt during normal driving to be able to measure and record the acting forces. However, the present invention is of course not limited to this area of application, but can always be used in all areas of application wherever possible and mobile detection of relatively small belt forces is required.

Die Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnung anhand eines bevorzugten Ausführungsbeispiels näher erläutert.The invention is described below with reference to the drawing preferred embodiment explained in more detail.

Fig. 1 zeigt eine Draufsicht auf eine erfindungsgemäße Gurtkraft-Meßanordnung, Fig. 1 shows a top view of an inventive belt force-measuring arrangement,

Fig. 2 zeigt eine Teilquerschnittsansicht entlang einer in Fig. 1 dargestellten Schnittlinie A-A', und Fig. 2 shows a partial cross-sectional view along a section line A-A 'shown in Fig. 1, and

Fig. 3 zeigt einen in Fig. 1 und Fig. 2 dargestellten Klemmbügel. Fig. 3 shows a clamp shown in Fig. 1 and Fig. 2.

Die in Fig. 1 gezeigte mobile Gurtkraft-Meßanordnung zum Messen der auf einen Gurt 1, insbesondere einen Kfz-Sicherheitsgurt, wirkenden Gurtkräfte, umfaßt als wesentliche Bestandteile einen Kraftmeßelement-Träger 3, damit verbundene oder daran befestigte Ösen 2, durch die jeweils das Gurtband 1 wie in Fig. 2 gezeigt zu führen ist, sowie einen in Einzeldarstellung in Fig. 3 gezeigten Klemmbügel 5 mit Fixierelementen 6, um das Gurtband 1 in den Öffnungen der beiden Ösen zu fixieren und somit die Gurtkraft-Meßanordnung in einer gewünschten Position an dem Gurt 1 zu befestigen.The mobile belt force measuring arrangement shown in FIG. 1 for measuring the belt forces acting on a belt 1 , in particular a motor vehicle seat belt, comprises as essential components a force measuring element carrier 3 , eyelets 2 connected to or attached to them, through which the belt strap in each case 1 as shown in Fig. 2, and a clamp 5 shown in an individual view in Fig. 3 with fixing elements 6 to fix the webbing 1 in the openings of the two eyelets and thus the belt force measuring arrangement in a desired position on the Attach strap 1 .

Auf dem Kraftmeßelement-Träger 3 ist ein Kraftmeßelement 4 angebracht, welches einen relativ kleinen Meßbereich, insbesondere < 10 N, aufweist. Bei dem in Fig. 1 gezeigten Kraftmeßelement 4 handelt es sich insbesondere um einen Dehnungsmeßstreifen, der bei Dehnung des in diesem Fall aus einem dehnbaren Material bestehenden Kraftmeßelement- Trägers 3 ein entsprechendes Meßsignal liefert, welches einer auf den Gurt 1 wirkenden Auszug- oder Rückzugkraft entspricht und von einem (nicht gezeigten) externen handelsüblichen Meßgerät nach entsprechender Eichung ausgewertet und aufgezeichnet werden kann.A force measuring element 4 , which has a relatively small measuring range, in particular <10 N, is attached to the force measuring element carrier 3 . The force measuring element 4 shown in FIG. 1 is, in particular, a strain gauge which, when the force measuring element carrier 3 , which in this case is made of a stretchable material, expands, supplies a corresponding measuring signal which corresponds to a pulling or pulling force acting on the belt 1 and can be evaluated and recorded by an external commercial measuring device (not shown) after appropriate calibration.

Zum Befestigen der Gurtkraft-Meßanordnung an dem Gurtband 1 wird folgendermaßen vorgegangen.The procedure for attaching the belt force measuring arrangement to the belt 1 is as follows.

An der zum Messen vorgesehenen Stelle des Gurtbands 1 wird das Gurtband beidseitig durch die Ösen 2 des Kraftmeßelement-Trägers 3 geführt, wobei dies insbesondere wie in Fig. 2 gezeigt geschieht. D. h. das Gurtband 1 wird in jede der beiden Ösen 2 sowohl von oben nach unten als auch wieder von unten nach oben (oder umgekehrt) geführt, so daß in jeder Öse 2 eine Gurtschlaufe vorhanden ist. In diese Gurtschlaufen werden die Fixierelemente 6 des Klemmbügels 5 seitlich derart eingeführt, daß das Gurtband 1 zwischen dem jeweiligen Fixierelement 6 und der Berandung der jeweiligen Öse 2 eingeklemmt wird.At the location of the webbing 1 intended for measurement, the webbing is guided on both sides through the eyelets 2 of the force measuring element carrier 3 , this taking place in particular as shown in FIG. 2. That is, the webbing 1 is guided in each of the two eyelets 2 both from top to bottom and again from bottom to top (or vice versa), so that a belt loop is present in each eyelet 2 . The fixing elements 6 of the clamping bracket 5 are laterally inserted into these belt loops in such a way that the belt strap 1 is clamped between the respective fixing element 6 and the edge of the respective eyelet 2 .

Wie aus Fig. 2 und Fig. 3 ersichtlich ist, können die Fixierelemente 6 insbesondere dreieckförmig oder giebeldachförmig ausgestaltet und mit ihrer Unterseite mit dem Klemmbügel 5 verbunden, beispielsweise aufgeschweißt sein. Durch die Dreiecksform wird gewährleistet, daß sich der Durchmesser des Fixierelements 6 zu der Öffnung der Öse 2 hin verringert, wobei jedoch Voraussetzung für die Klemmwirkung ist, daß der größte Durchmesser des Fixierelements 6 größer als der Öffnungsdurchmesser der entsprechenden Öse 2 ist. Der Spitzendurchmesser des dreieckförmigen Fixierelements ist kleiner als der Öffnungsdurchmesser der entsprechenden Öse 2, so daß die Spitze des Fixierelements 6 in die Ösenöffnung 2 hineinragen kann. Auf diese Weise wird insbesondere bei Ausübung einer beidseitigen Zugkraft auf das in der Öse 2 befindliche Gurtband 1 ein zuverlässiges Einklemmen und Arretieren des Gurtbands 1 in der Öse 2 gewährleistet. Selbstverständlich kann der Klemmbügel 5 bzw. die daran befestigten Fixierelemente 6 auch andersartig geformt sein.Such as 3 can be seen from Fig. 2 and Fig., The fixing elements 6 can be embodied in particular triangular or gabled roof shape and is connected to its underside with the clamp 5, for instance welded on. The triangular shape ensures that the diameter of the fixing element 6 decreases towards the opening of the eyelet 2 , although the prerequisite for the clamping effect is that the largest diameter of the fixing element 6 is larger than the opening diameter of the corresponding eyelet 2 . The tip diameter of the triangular fixing element is smaller than the opening diameter of the corresponding eyelet 2 , so that the tip of the fixing element 6 can protrude into the eyelet opening 2 . In this way, a double-sided tensile force is ensured to the left in the eyelet 2 webbing 1 a reliable clamping and locking of the webbing 1 in the eyelet 2 in particular upon exercise. Of course, the clamp 5 or the fixing elements 6 attached to it can also be shaped differently.

Nach Anschluß des Kraftmeßelements 4 an ein Meßgerät kann schließlich die gewünschte Gurtkraftmessung durchgeführt werden.After connecting the force measuring element 4 to a measuring device, the desired belt force measurement can finally be carried out.

Die in Fig. 1 - Fig. 3 gezeigte Gurtkraft-Meßanordnung kann jederzeit wieder von dem Gurtband 1 gelöst werden, wozu einfach der Klemmbügel 5 mit den daran befestigten Fixierelementen 6 seitlich aus den beiden Gurtschlaufen herausgezogen werden muß. Anschließend kann die Meßanordnung wie oben beschrieben wieder an jeder beliebigen Stelle desselben Gurtbands 1 oder auch eines anderen Gurtbands befestigt werden.In Fig. 1 -. Belt force-measuring arrangement shown Figure 3 may be released at any time of the strap 1, including simply the clamp strap 5 has to be pulled with the attached fixing elements 6 side of the two belt loops. The measuring arrangement can then be fastened again at any desired point on the same webbing 1 or on another webbing as described above.

Anstelle der oben beschriebenen Ösenlösung mit Klemmbügel sind auch andere Lösungen denkbar, die ein Anbringen der Gurtkraft-Meßanordnung an einer beliebigen Stelle des Gurtbands 1 erlauben. So ist beispielsweise eine Ausgestaltung der Gurtkraft- Meßanordnung derart möglich, daß sie an dem Gurtband 1 mit Hilfe von Klemmen lösbar befestigt werden kann. Darüber hinaus können neben Dehnungsmeßstreifen selbstverständlich auch andere Kraftaufnehmer als Kraftmeßelement 4 verwendet werden. Instead of the eyelet solution described above with a clamp, other solutions are also conceivable that allow the belt force measuring arrangement to be attached at any point on the belt 1 . For example, a configuration of the belt force measuring arrangement is possible in such a way that it can be detachably attached to the belt 1 with the aid of clamps. In addition to strain gauges, other force transducers can of course also be used as the force measuring element 4 .
