Abstract
Description
Die Erfindung betrifft einen Aufprallsensor gemäß dem Oberbegriff von Anspruch 1. The invention relates to a crash sensor according to the preamble of
Ein Kraftfahrzeug weist häufig einen, oft auch mehrere Aufprallsensoren zur Erzeugung eines von der Art und/oder Stärke des Aufpralls abhängigen Signals auf. A motor vehicle often has one, often also several impact sensors for generating a dependent on the nature and / or magnitude of the impact signal.
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
Aus der
Die Aufgabe der vorliegenden Erfindung ist es, eine besonders geeignete Ausgestaltung eines solchen Aufprallsensors sowie ein Verfahren zur Herstellung anzugeben, bei dem auf das Klemmmittel und dessen Anbringung verzichtet werden kann. 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 and a method for manufacturing, in which it is possible to dispense with the clamping means and its attachment. 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 Anschlussrohrstück des Gehäuses des Drucksensors angeklebt wird. So konnte durch Versuche festgestellt werden, dass durch eine Klebeverbindung, insbesondere in Verbindung mit vorteilhaften konstruktiven Weiterbildungen des Anschlussrohrstücks eine vergleichbare Festigkeit des Schlauchs gegen Abziehen als auch eine entsprechende Druckdichtheit erreicht werden kann. Entsprechende Weiterbildungen sind der Beschreibung als auch in den Unteransprüchen zu entnehmen. An essential idea of the invention is that the pressure sensor is glued to the connecting pipe piece of the housing of the pressure sensor. It has been found by experiments that a comparable strength of the hose against peeling and a corresponding pressure tightness can be achieved by an adhesive bond, in particular in conjunction with advantageous structural developments of the connecting pipe piece. Corresponding developments are to be found in the description as well as in the dependent claims.
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.

2.2 , whose outer diameter D2.2 has a predetermined excess compared to the inner diameter D1 of the hose in the tension-free state, so that thehose 1 in this section is curious and is pressure-tight on this 2nd section2.2 of the connecting pipe piece presses - c) a third section
2.3 , which has an outer diameter D2.3 smaller than the Outer diameter D2.2 in the second section, preferably still slightly larger than the inner diameter D1 of the hose in the relaxed state.
