Der Kraftmeßelement-Träger (3) ist beidseitig mit Ösen (2) verbunden, in die der Gurt (1) eingeführt und mit Hilfe eines Klemmbügels (5, 6) fixiert werden kann. Als Kraftmeßelement (4) kann beispielsweise ein Dehnungsmeßstreifen verwendet werden.A force measuring element support (3) for measuring forces acting on a safety belt during normal driving comprises a force measuring element support (3) on which a force measuring element (4) for generating a measuring signal corresponding to a force acting on the belt (1), is ordered. The Kraftmeßelement carrier (3) is connected on both sides with eyelets (2), in which the belt (1) can be inserted and fixed by means of a clamping bracket (5, 6). As a force measuring element (4), for example, a strain gauge can be used.
Description
Die vorliegende Erfindung betrifft eine Gurtkraft-Meßanordnung, mit der sich auf einen Gurt, insbesondere einen Kraftfahrzeug-Sicherheitsgurt, wirkenden Kräfte messen lassen.The The present invention relates to a belt force measuring device with which a belt, in particular a motor vehicle seat belt, acting personnel can be measured.
Für Kraftfahrzeuge
sind unterschiedliche Sicherheitsgurtsysteme bekannt. So wird beispielsweise
in der
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 Such safety belt systems are accurate knowledge of the while normal driving and in the event of an accident and forces acting on the seatbelt are required. So already are Kraftmeßanordnungen known in crash tests during an accident on the Safety belt acting forces can capture. Because while an accident considerable pulling forces act on the safety belt, these force measuring arrangements have a measuring range> 10 kN.
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.These known measuring arrangements However, they are not suitable for use during normal driving detecting pull-out or withdrawal forces acting on the seatbelt, since these are several orders of magnitude lie below the tensile forces occurring in an accident. For measuring such small forces, the while occur during normal driving, but are Kraftmeßanordnungen 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.Of the The present invention is therefore based on the object to provide a belt force measuring arrangement, which is simple and reliable measurement of relatively small forces which can act on a belt, allows. Especially should the belt force measuring arrangement for use in motor vehicles for the measurement of during the normal driving operation on the seat belt of the motor vehicle acting extract and / or Suitable for retreat and be designed 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.These Problem is in accordance with the present invention by a belt force measuring arrangement solved with the features of claim 1. Define the subclaims respectively preferred and advantageous embodiments of the present invention 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 load cell carrier on which a force measuring element for generating a measuring signal, which corresponds to a force acting on the belt, attached is, Gurtaufnahmemittel, which arranged on two sides of the Kraftmeßelementträger and connected to this, to the strap on the two sides of the To include load cell carrier, and strap attachment means to the strap in the strap receiving means to fix.
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 measurement, in the as a force measuring element in particular a strain gauge (DMS) with a measuring range <20 N used can be, is designed such that they are detachable from the belt and can be placed anywhere in another place. To this end can the Gurtbefestigungsmittel designed eye-shaped be so that the Belt in the form of a loop in each of the eyelets both in and out led out becomes. In each belt loop then a fixing element of the belt fastening means introduced, which has a larger diameter as the opening the corresponding eyelet owns, so that in every eyelet a reliable one Fixation of the belt possible is.
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, around without impairment normal driving and without the safety belt system being remodeled the while Measure forces acting on the seat belt during normal driving and to be able to grasp. Of course, the present invention is not limited to this field of application limited, but basically be used in all fields of application, where possible flexible and mobile detection of relatively small belt forces required is.
Die Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnung anhand eines bevorzugten Ausführungsbeispiels näher erläutert.The Invention will be described below with reference to the drawing a preferred embodiment explained in more detail.
