Abstract
Aufprallsensor bestehend aus einem bei einem Aufprall elastisch deformierbaren Schlauch mit einem Hohlraum und zumindest einem Drucksensor zur Erfassung der Druckänderung im Hohlraum des Schlauchs, dadurch gekennzeichnet, dass der Drucksensor am Gehäuse ein Anschlussrohrstück aufweist, wobei der Schlauch mit einem Klemmmittel (5) am Anschlussrohrstück befestigt ist, wobei der Schlauch nur durch Zerstörung des Klemmmittels (5) vom Anschlussrohrstück lösbar ist.Impact sensor consisting of a hose which is elastically deformable in the event of an impact and has a cavity and at least one pressure sensor for detecting the pressure change in the cavity of the hose, characterized in that the pressure sensor has a connection pipe section on the housing, the hose being fastened to the connection pipe section with a clamping means (5) is, wherein the hose can only be released from the connecting pipe piece by destroying the clamping means (5).
Description
Die Erfindung betrifft einen Aufprallsensor gemäß dem Oberbegriff von Anspruch 1.The invention relates to a crash sensor according to the preamble of claim 1.
Ein Kraftfahrzeug weist dabei mindestens einen, oft auch mehrere Aufprallsensoren zur Erzeugung eines von der Art und/oder Stärke des Aufpralls abhängigen Signals auf.In this case, a motor vehicle has at least one, often also a plurality of impact sensors for generating a signal which depends on the type and / or magnitude of the impact.
Ein dazu geeigneter Aufprallsensor besteht beispielsweise aus einem elastisch deformierbaren Schlauch mit einem Hohlraum und zumindest einem Drucksensor zur Erfassung der Druckänderung im Hohlraum des Schlauchs. Derartige Aufprallsensoren dienen in Kraftfahrzeugen der Erkennung von Aufprallsituationen, insbesondere auch der Unterscheidung eines Aufpralls eines Fußgängers von anderen Aufprallereignissen und sind beispielsweise aus der
Die Aufgabe der vorliegenden Erfindung ist es, eine besonders geeignete Ausgestaltung eines solchen Aufprallsensors anzugeben. Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen der Erfindung ergeben sind aus den Unteransprüchen, wobei auch Kombinationen und Weiterbildungen einzelner Merkmale miteinander denkbar sind.The object of the present invention is to provide a particularly suitable embodiment of such an impact sensor. This object is solved by the features of the independent claims. Advantageous developments of the invention will become apparent from the dependent claims, wherein combinations and developments of individual features are conceivable with each other.
Ein wesentlicher Gedanke der Erfindung besteht darin, dass der Drucksensor am Gehäuse ein Anschlussrohrstück aufweist, wobei der Schlauch mit einem Klemmmittel am Anschlussrohrstück befestigt ist, wobei der Schlauch nur durch Zerstörung des Klemmmittels vom Anschlussrohrstück lösbar ist. Als bevorzugtes Klemmmittel erweist sich ein Stahlzungenkabelbinder, da im Gegensatz zu anderen Kabelbindern die Stahlzunge sich in das Flachband verhakt und ein Zurückziehen des Flachbands sicher verhindert.An essential idea of the invention is that the pressure sensor has a connecting pipe piece on the housing, wherein the hose is fastened with a clamping means on the connecting pipe piece, whereby the hose can be detached from the connecting pipe piece only by destroying the clamping means. The preferred clamping means is a steel tongue cable tie, since, in contrast to other cable ties, the steel tongue hooks into the ribbon and reliably prevents retraction of the flat strip.
Durch eine Kennung am Klemmmittel, anhand der das Klemmmittel zumindest einem bestimmten Lieferweg zuordenbar ist, kann auch sichergestellt werden, dass nicht durch andere Klemmmittel eine Manipulation am Schlauchanschluss nicht entdeckt werden kann.By an identifier on the clamping means, by means of which the clamping means can be assigned to at least one specific delivery path, it can also be ensured that manipulation on the hose connection can not be detected by other clamping means.
Die Erfindung wird nun nachfolgend anhand eines Ausführungsbeispiels unter Zuhilfenahme der Figuren näher erläutert. Im Folgenden können für funktional gleiche und/oder gleiche Elemente mit den gleichen Bezugsziffern bezeichnet sein.The invention will now be explained in more detail below with reference to an embodiment with the aid of the figures. Hereinafter, for functionally identical and / or identical elements may be denoted by the same reference numerals.

- a) einen ersten Abschnitt
6.1 , dessen Außendurchmesser kleiner ist als der Innendurchmesser des Schlauchs im spannungsfreien Zustand, so dass derSchlauch 3 beim Aufschieben auf das Anschlussrohrstück6 eine Führung und Positionshilfe erhält - b) einen zweiten Abschnitt
6.2 , dessen Außendurchmesser ein vorgegebenes Übermaß gegenüber dem Innendurchmesser des Schlauchs im spannungsfreien Zustand aufweist, so dass derSchlauch 3 in diesem Abschnitt gespannt ist und sich druckdicht auf diesen 2. Abschnitt6.2 des Anschlussrohrstücks presst - c) einen dritten Abschnitt
6.3 , der einen Außendurchmesser kleiner als der Außendurchmesser im zweiten Abschnitt aufweist und in diesem dritten Abschnitt dasKlemmmittel 5 befestigt ist, wobei dasKlemmmittel 5 neben seiner Klemmwirkung auf denSchlauch 3 auch durch das Untergreifen des Abschnitts6.2 gegen ein Abziehen vom Anschlussrohrstück6 gesichert ist.
- a) a first section
6.1 , whose outer diameter is smaller than the inner diameter of the hose in the tension-free state, so that thehose 3 when pushed onto the connecting pipe piece6 get a leadership and position help - b) a second section
6.2 whose outer diameter has a predetermined oversize relative to the inner diameter of the hose in the tension-free state, so that thehose 3 in this section is curious and is pressure-tight on this 2nd section6.2 of the connecting pipe piece presses - c) a third section
6.3 having an outer diameter smaller than the outer diameter in the second portion and in this third portion the clamping means5 is attached, wherein the clamping means5 in addition to its clamping action on thehose 3 also by taking under the section6.2 against removal from the connecting pipe piece6 is secured.
In den Figuren nicht gezeigt, weist aber in der bevorzugten Ausgestaltung das Klemmmittel eine Kennung, also ein optisch oder anderweitig Sensorisch wahrnehmbare Information auf, anhand der das Klemmmittel zumindest einem bestimmten Lieferweg zuordenbar ist. Die Kennung beinhaltet also nicht nur den Hersteller des Klemmmittels, sondern auch eine Information über den Abnehmer, also beispielsweise den serienmäßigen Hersteller dieser Aufprallsensoren oder sogar eine spezielle Kennnummer oder individuelle Teilenummer.Not shown in the figures, but in the preferred embodiment, the clamping means an identifier, so an optically or otherwise sensory perceptible information on the basis of the clamping means is at least one particular delivery path can be assigned. The identifier thus includes not only the manufacturer of the clamping means, but also information about the customer, so for example, the standard manufacturer of these impact sensors or even a special identification number or individual part number.
Eine derartige Kennung ist auf herkömmlichen Klemmmitteln in nicht vorgesehen und können daher Aufprallsensoren nicht nachträglich manipuliert und durch gleichartige Klemmmittel wieder verschlossen werden.Such an identifier is not provided on conventional clamping means in and therefore impact sensors can not be subsequently manipulated and closed again by similar clamping means.
