Abstract
Description
Die vorliegende Erfindung betrifft eine Druck-Messvorrichtung zum Messen der vom Gurt auf einen Oberkörper wirkenden Kraft, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The present invention relates to a pressure measuring device for measuring the force acting on a torso by the belt, having the features of the preamble of
Komfortable Sicherheitsgurtsysteme besitzen eine Vorspanneinrichtung, die den Gurt stets mit einer gewissen Vorspannung beaufschlagt, um eine so genannte Gurtlose zu reduzieren und das Aufrollen des Sicherheitsgurtes nach dem Anschnallen sicherzustellen. Zur Untersuchung der mit Hilfe der Spanneinrichtung in den Gurt einbringbaren Vorspannkraft, die auch zum selbsttätigen Aufrollen des Gurts verwendet wird, wenn der Gurt nicht benötigt wird, können Druck-Messvorrichtungen verwendet werden.Comfortable safety belt systems have a pretensioning device which always applies a certain pretension to the belt in order to reduce so-called belt slack and to ensure that the seat belt is rolled up after it has been buckled up. In order to examine the biasing force which can be introduced into the belt by means of the tensioning device and which is also used for automatically winding up the belt when the belt is not required, pressure measuring devices can be used.
Aus der
Bei der bekannten Gurtkraft-Messvorrichtung muss zur exakten Messung der am Gurt wirkenden Kraft sichergestellt sein, dass sich der Gurt im jeweiligen Bügel nicht mehr bewegen kann und zwischen den Bügeln nicht gespannt ist. Ferner darf der Klemmbügel keine Kräfte aufnehmen und so um das Kraftmesselement herumleiten. Die bekannte Gurtkraft-Messvorrichtung ist zur Messung kleiner Gurtkräfte ungeeignet. Ferner ist die bekannte Gurtkraft-Messvorrichtung ungeeignet, die Druckverteilung zu erfassen, die vom Gurt auf den Insassen, insbesondere auf dessen Oberkörper, im angeschnallten Zustand wirkt.In the known belt force measuring device must be ensured for accurate measurement of the force acting on the belt that the belt can not move in the respective bracket and is not stretched between the brackets. Furthermore, the clamp must not absorb forces and thus lead around the force measuring element. The known belt force measuring device is unsuitable for measuring small belt forces. Furthermore, the known belt force measuring device is unsuitable to detect the pressure distribution, which acts on the occupant, in particular on the upper body, in the buckled state of the belt.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Druck-Messvorrichtung der eingangs genannten Art eine verbesserte oder zumindest eine andere Ausführungsform anzugeben, die sich insbesondere durch einen einfachen Aufbau sowie durch verbesserte Messergebnisse auszeichnet.The present invention is concerned with the problem of providing for a pressure measuring device of the type mentioned an improved or at least another embodiment, which is characterized in particular by a simple structure and improved measurement results.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matter of the independent claim. Advantageous embodiments are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, die Druck-Messvorrichtung mit einem Prüfkörper auszustatten, der auf einen dem zu messenden Gurt zugeordneten Sitz positionierbar ist. Die Messeinrichtung befindet sich auf einem Prüfkörper, der auf einem Sitz positionierbar ist, der dem zu messenden Gurt zugeordnet ist, wobei die Messeinrichtung auf dem Prüfkörper zumindest in dem Bereich vorgesehen ist, auf dem der Gurt im angelegten Zustand verläuft. Damit kann die Druckverteilung gemessen werden, wie sie vom angelegten Gurt auf den Prüfkörper aufgebracht wird.The invention is based on the general idea of equipping the pressure-measuring device with a test piece which can be positioned on a seat assigned to the belt to be measured. The measuring device is located on a test piece which can be positioned on a seat which is assigned to the belt to be measured, wherein the measuring device is provided on the test piece at least in the region on which the belt runs in the applied state. Thus, the pressure distribution can be measured, as applied by the applied belt on the specimen.
Vorzugsweise ist die Messeinrichtung eine Drucksensorfolie, die auf die Frontseite des Prüfkörpers aufgebracht werden kann. Damit kann die Oberflächen-Druckverteilung bei jedem beliebigen Verlauf des angelegten Gurtes überprüft werden. Die Drucksensorfolie ist dabei für die relativ geringen Druckwerte bei einem angelegten Gurt auszulegen.Preferably, the measuring device is a pressure sensor film which can be applied to the front side of the test specimen. Thus, the surface pressure distribution can be checked for any course of the applied belt. The pressure sensor film is to be interpreted for the relatively low pressure values for a belt applied.
Durch die vorgeschlagene Bauweise der Druck-Messvorrichtung lassen sich die auf den Insassenoberkörper wirkenden Drücke realitätsnah erfassen. Eine entsprechende Auswerteeinheit kann die anliegenden Drücke über den Gurtverlauf z. B. farblich visualisieren. Ferner zeichnet sich die hier vorgestellte Druck-Messvorrichtung durch einen preiswerten Aufbau aus.Due to the proposed design of the pressure-measuring device, the pressures acting on the occupant upper body can be detected in a realistic manner. A corresponding evaluation, the applied pressures on the belt z. B. visualize in color. Furthermore, the pressure measuring device presented here is characterized by a low-cost construction.
Besonders vorteilhaft ist es ferner, wenn der Prüfkörper hinsichtlich seiner Form einem menschlichen Torso nachempfunden ist. Die erzielbaren Messergebnisse werden dadurch besonders realitätsnah. Der Torso kann auf unterschiedliche Körpergrößen oder Körperformen abgebildet werden.It is also particularly advantageous if the test specimen is modeled on a human torso with respect to its shape. The achievable measurement results are therefore very realistic. The torso can be mapped to different body sizes or body shapes.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.
Bevorzugte Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden in der nachfolgenden Beschreibung näher erläutert, wobei sich gleiche Bezugszeichen auf gleiche oder ähnliche oder funktional gleiche Bauteile beziehen.Preferred embodiments of the invention are illustrated in the drawings and will be described in more detail in the following description, wherein like reference numerals refer to the same or similar or functionally identical components.
