Bei zukünftigen Airbaggenerationen
soll laut der amerikanischen Gesetzgebung FMVSS
Aktuell wird die Insassenklassifizierung mit Systemen durchgeführt, die den Fahrzeuginnenraum sensieren. Beispiele hierzu sind die Gewichtsmatte, die Bladdermatte, Video- oder Ultraschallsysteme. Für die Überprüfung des im Beifahrersitz implementierten Insassenklassifizierungssystems wird in der Serienproduktion häufig keine Serienprüfung, sondern nur eine Auditprüfung durchgeführt. Falls eine Serienprüfung für diese Systeme realisiert wird, welche vermutlich im Hinblick auf die zunehmende Genauigkeit der Systeme gerade im Zusammenhang mit der Gesetzgebung in den USA nötig wird, geschieht dies mit aufwändigen und teuren Prüftürmen. Der Einsatz dieser Prüftürme ist auch ein bedeutender Zeitfaktor in der Sitzfertigung.The occupant classification is currently carried out using systems that sense the interior of the vehicle. Examples include the weight mat, the bladder mat, video or ultrasound systems. To check the occupant classification system implemented in the front passenger seat, serial testing is often not carried out in series production, but only an audit test. If a series test is carried out for these systems, which is probably necessary in view of the increasing accuracy of the systems, especially in connection with the legislation in the USA, this is done with complex and expensive test towers. The use of these test towers is also an important time factor in seat production.
Erfindungsgemäß wird deshalb zu einer einfachen Überprüfung des korrekten Einbaus bzw. der Erkennungsleistung des im Sitz implementierten Insassenklassifizierungssystems in der Serienproduktion eine Vorrichtung zur Überprüfung eines zumindest teilweise in einem Fahrzeugsitz eingebauten Insassenklassifizierungssystems vorgeschlagen, das die Beaufschlagung eines Drucks auf die Sitzfläche ermöglicht und mit einem Rechner verbunden ist, um das Signal des Insassenklassifizierungssystems mit dem beaufschlagten Druck zu vergleichen, um die Funktionsprüfung durchzuführen. Vorzugsweise wird dazu ein Einhandtester verwendet, der mit dem Rechner verbunden ist und durch ein einfaches Aufdrücken des Prüfkopfs eine Überprüfung des Systems ermöglicht. Dies führt zu einer Hundert-Prozent-Prüfung des Insassenklassifizierungssystems am Bandende, die einfacher und kostengünstiger ist. Die Einzelsitze müssen nicht aufwändige Prüftore durchlaufen.According to the invention is therefore a simple check of the correct installation or the recognition performance of the implemented in the seat Occupant classification system in series production a device to check a At least partially occupant classification system installed in a vehicle seat proposed that allows the application of pressure on the seat and is connected to a computer for the signal of the occupant classification system to be compared with the pressure applied in order to carry out the functional test. Preferably a one-hand tester is used, which is connected to the computer and by simply pressing the test head on, a check of the Systems enables. this leads to for a hundred percent check of the End-of-line occupant classification system that is easier and less expensive is.
