Eine Vielzahl von Funktionen in einem Kraftfahrzeug werden vorzugsweise in Abhängigkeit einer Belegung eines Sitzes geschaltet. Hierzu gehören Funktionen zur Erhöhung der Sicherheit von Passagieren, wie beispielsweise optische und/oder akustische Warnhinweise zum Anlegen eines Sicherheitsgurts, Auslösevorrichtungen für Airbags etc. Die Belegung von Sitzen ist weiter von Interesse für Komfortfunktionen, wie Sitzheizung, verstellbare Nackenstützen, und andere. Die Belegung eines Sitzes ist anhand einer Belastung erfassbar. Neben der Erkennung der Belastung ist auch eine optische Erkennung einer Sitzplatzbelegung denkbar.A Variety of functions in a motor vehicle are preferably dependent on switched to a seat occupancy. These include functions to increase the safety of passengers, such as optical and / or acoustic warnings for putting on a safety belt, tripping devices for airbags etc. The occupancy of seats is still of interest for comfort functions, like heated seats, adjustable neckrests, and others. The occupancy of a seat can be detected by means of a burden. In addition to detection The load is also an optical recognition of a seat occupancy conceivable.

Der Erfindung liegt daher das technische Problem zugrunde, eine Vorrichtung und ein Verfahren zu schaffen, durch welche eine Belastung eines Sitzes zuverlässig erkennbar ist und die eine kostengünstige Montage und/oder Herstellung ermöglichen.Of the The invention is therefore based on the technical problem of a device and to provide a method by which a load of a seat reliable is recognizable and the cost-effective installation and / or manufacture enable.
Die Lösung des Problems ergibt sich durch die Gegenstände mit den Merkmalen der Patentansprüche 1 und 6. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution of the problem results from the objects with the features of claims 1 and 6. Further advantageous embodiments of the invention will become apparent from the dependent claims.
Hierfür ist mindestens ein als Leiste ausgebildetes Schaltelement in einen Fahrzeugsitz integriert. Das Schaltelement schließt aufgrund einer Belastung, so dass ein Stromkreis geschlossen und/oder ein Signal erzeugt wird. Die Leiste umfasst einen verformbaren Mantel und mindestens zwei Leiterbahnen. Die Leiterbahnen sind in dem Mantel derart angeordnet, dass sie sich im unverformten Zustand nicht berühren. Bei einer Belastung, welche einen festgelegten Schwellwert überschreitet, berühren sich die Leiterbahnen an mindestens einer Stelle. Sind die Leiterbahnen mit einem Stromkreis verbunden, so wird dieser dadurch geschlossen, so dass eine Warneinrichtung und/oder eine andere Einrichtung aktivierbar ist. Aufgrund der kompakten Bauform ist das Schaltelement robust gegen Ermüdungserscheinungen. Zudem erlaubt die Ausbildung als Leiste eine einfache Montage des Schaltelements im Sitz. Dabei ist es denkbar, mehrere Schaltelemente parallel und/oder als Gitter angeordnet in dem Sitz zu integrieren. Der Schwellwert ist beispielsweise in Abhängigkeit des Sitzes einstellbar. So ist es denkbar, für einen Fahrersitz eine geringere Sensitivität vorzusehen als für einen Rücksitz, da der Fahrersitz im Regelfall nicht durch Personen unter einer gesetzlich vorgegebenen Altersgrenze belegt ist. Schwellwerte sind geeignet zu wählen, so dass eine geringe Belastung beispielsweise durch eine Tasche nicht zu einem Schließen des Schaltelements führt. Selbstverständlich ist es auch denkbar, das Schaltelement derart auszubilden, dass aufgrund der Belastung ein Schaltkreis geöffnet und/oder ein Signal unterbrochen wird. Im Regelfall ist jedoch ein Schließen des Schaltkreises bei Belastung aus energetischen Aspekten zu bevorzugen.This is at least a trained as a bar switching element in a vehicle seat integrated. The switching element closes due to a load, so that a circuit is closed and / or a signal is generated. The bar includes a deformable coat and at least two Interconnects. The conductor tracks are arranged in the jacket in such a way that they do not touch each other when undeformed. At a load, which exceeds a specified threshold, touch each other the tracks in at least one place. Are the tracks connected to a circuit, it is closed by so that a warning device and / or another device can be activated is. Due to the compact design, the switching element is robust against signs of fatigue. In addition, the training as a bar allows easy installation of the Switching element in the seat. It is conceivable, several switching elements in parallel and / or arranged as a grid to integrate in the seat. The threshold is, for example, dependent the seat adjustable. So it is conceivable for a driver's seat a lower sensitivity to be provided for a backseat, because the driver's seat is usually not by persons under one legally prescribed age limit. Thresholds are suitable to choose so that a small load for example through a bag not to a close of the switching element leads. Of course it is also conceivable to form the switching element such that due to the load a circuit opened and / or a signal interrupted becomes. As a rule, however, is a closing of the circuit under load to prefer from energetic aspects.
In einer weiteren Ausführungsform ist der Sitz mit einer Nut ausgebildet, in welche die Leiste eingelegt wird. Die Nut kann beispielsweise in Sitzkissen bestehender Fahrzeugsitze für eine Aufrüstung eingearbeitet werden. Für die Nuten sind keinen engen Toleranzen erforderlich und sie sind durch bekannte Werkzeuge kostengünstig herstellbar. Gleiches gilt für die Montage der Leiste in der Nut.In a further embodiment the seat is formed with a groove in which the bar inserted becomes. The groove can be used, for example, in seat cushions of existing vehicle seats for one arming be incorporated. For the grooves are not required to tight tolerances and they are inexpensive by known tools produced. The same applies to the assembly of the strip in the groove.
In einer weiteren bevorzugten Ausführungsform wird die Leiste beim Schäumen eines Sitzkissens des Sitzes eingeschäumt. Dadurch ist das Schaltelement bereits im Fertigungsprozess in den Sitz integrierbar. Durch den Mantel ist die Leiste vor einem Zusammendrücken im Schäumungsprozess geschützt. Flächige Ausführungsformen werden dagegen durch den Schaum zusammengedrückt und sind daher nicht in den Fertigungsprozess integrierbar.In a further preferred embodiment becomes the strip during foaming a seat cushion of the seat foamed. This is the switching element Already integrated into the seat during the manufacturing process. By the Sheath is the ledge protected from squeezing in the foaming process. Flat embodiments however, are compressed by the foam and are therefore not in the manufacturing process can be integrated.
In einer weiteren bevorzugten Ausführungsform ist der Mantel aus nichtleitendem und die Leiterbahnen aus leitendem Kunststoff ausgebildet. Die Leiterbahnen sind in den Mantel eingespritzt. Durch den Mantel ist eine gute Isolierung gegeben, so dass keine weiteren Schutzvorrichtungen notwendig sind. Die Leisten sind durch Spritzen günstig herstellbar. Daneben ist es denkbar, bekannte Standardleisten einzusetzen, welche eine gewünschte Steifigkeit aufweisen.In a further preferred embodiment the cladding is nonconductive and the conductive traces are conductive Plastic formed. The tracks are injected into the jacket. By the coat is given a good insulation, so that no further Protection devices are necessary. The strips are by injection Cheap produced. In addition, it is conceivable to use known standard strips, which a desired Have stiffness.
In einer weiteren Ausführungsform ist der Mantel aus einem hochtemperaturbeständigen, elastischen Thermoplasten ausgebildet. Daneben sind andere Materialien denkbar. Insbesondere wenn die Leiste durch Schäumen in den Sitz eingearbeitet werden soll, sind die jedoch die Materialien derart zu wählen, dass sie beständig gegen die hohen Temperaturen des Schäumungsprozesses sind.In a further embodiment is the jacket made of a high temperature resistant, elastic thermoplastic educated. In addition, other materials are conceivable. Especially when the bar is frothing to be incorporated into the seat, but these are the materials to choose such that they are consistent against the high temperatures of the foaming process.
