This ensures a large and particularly robust electrical connection between the seat and the vehicle. In addition, this method is particularly simple and inexpensive, since only contact surfaces on the
Befestigungsvorrichtung und an dem Fahrzeug vorzusehen sind. Weiterhin ermöglicht diese Lösung die Übertragung relativ hoher Energie, da eine großflächige Kontaktfläche vorhanden ist. Die Gefahr unerwünschter Signaleinkopplungen wird vermieden und somit bei Rückhaltesystemen eine Fehlauslösung unterdrückt.

Furthermore, this solution enables the transfer of relatively high energy, since there is a large contact area. The risk of unwanted signal coupling is avoided and false triggering is suppressed in restraint systems. Interference emissions are also reduced, with relatively high currents and relatively high voltages, more than 500 mA or 12 V being expected, causing a contact cleaning effect.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen und Weiterbildungen sind vorteilhafte Verbesserungen des im unabhängigen Patentanspruch angegebenen herausnehmbaren Fahrzeugsitzes möglich.The measures and developments listed in the dependent claims allow advantageous improvements to the removable vehicle seat specified in the independent claim.
Besonders vorteilhaft ist, daß die Befestigungsvorrichtung wenigstens zwei Haken aufweist, die am Fahrzeugsitz angebracht sind und zum Einbau jeweils einen Metallstab, der im Fahrzeug angebracht ist, zumindest teilweise umfassen. Die zwei Haken weisen dabei eine Kontaktfläche auf, die dann eine elektrische Verbindung mit dem jeweiligen Metallstab herstellt. Über diese elektrische Verbindung können dann relative hohe elektrische Energien und auch Daten übertragen werden .It is particularly advantageous that the fastening device has at least two hooks which are attached to the vehicle seat and each comprise at least partially a metal rod which is attached to the vehicle for installation. The two hooks have a contact surface, which then establishes an electrical connection with the respective metal rod. Relatively high electrical energies and also data can then be transmitted via this electrical connection.

Die Haken sind dabei vorteilhafterweise als Klammerhaken ausgebildet, die beim Befestigen geschlossen werden. Die Befestigungsvorrichtung kann auch nur zur Energieübertragung verwendet werden, wobei dann für die Datenübertragung eine drahtlose Funkübertragung verwendet wird, so daß es möglich ist, die Funktionsfähigkeit der elektrischen Energieübertragung auf diese Weise über einen redundanten Übertragungsweg zu überwachen. Für diese Datenkommunikation im Hochfrequenzbereich sind die sogenannten ISM-Frequenzbänder verwendbar. Die Überwachung der Stromübertragung wird bspw. durch einen Vergleich der im Fahrzeugsitz gemessenen Bordnetzspannung mit der vom zentralen Steuergerät gemessenen Spannung möglich.The hooks are advantageously designed as clip hooks that are closed when fastening. The fastening device can also be used only for energy transmission, a wireless radio transmission then being used for the data transmission, so that it is possible to monitor the functionality of the electrical energy transmission in this way via a redundant transmission path.

In Fahrzeugsitzen sind elektrische Komponenten angeordnet, bspw. eine Sitzmatte, um zu erkennen, ob eine Person sich auf dem Sitz befindet, einen Seitenairbag um bei einem Seitenaufprall eine Person, die sich auf dem Sitz befindet, zu schützen und andere Diagnoseelektroniken. Da in einigen Fahrzeugen für die Kunden herausnehmbare Sitze angeboten werden, so daß sie sich bei Bedarf einen größeren Stauraum in ihrem Fahrzeug bereitstellen können, ist es notwendig, für die Elektroniken, die sich in den herausnehmbaren Sitzen befinden, eine elektrische Versorgung und ggf. eine Datenübertragungsmöglichkeit sicherzustellen. Diese werden vorteilhafterweise bereits durch den Einbau des Fahrzeugsitzes selbst realisiert.Electrical components are arranged in vehicle seats, for example a seat mat to detect whether a person is on the seat, a side airbag to protect a person who is in the seat in the event of a side impact, and other diagnostic electronics. Since in some vehicles removable seats are offered to customers so that they can provide a larger storage space in their vehicle if necessary, it is necessary for the electronics that are in the removable seats, an electrical supply and possibly a Ensure the possibility of data transmission.

Erfindungsgemäß wird hier die Befestigungsvorrichtung für den Fahrzeugsitz derart weitergebildet, so daß sie auch zur elektrischen Energie- und/oder Datenübertragung einsetzbar ist. In einer Weiterbildung ist vorgesehen, daß Haken, die zum Einbau des Fahrzeugsitz verwendet werden und dabei Metallstäbe zumindest teilweise umfassen, mit Kontaktflächen ausgestattet werden, die dann mit den Metallstäben in innige Berührung kommen, um eine elektrische Verbindung herzustellen. Auch die Metallstäbe weisen dann an den entsprechenden Stellen entsprechende Kontaktflächen auf.According to the invention, the fastening device for the vehicle seat is developed in such a way that it can also be used for electrical energy and / or data transmission. In a further development it is provided that hooks which are used to install the vehicle seat and which at least partially comprise metal rods are equipped with contact surfaces which then come into intimate contact with the metal rods in order to establish an electrical connection. The metal rods then also have corresponding contact surfaces at the corresponding points.
Durch die Großflächigkeit ist es dann möglich, relativ hohe elektrische Energien zu übertragen. Dabei ist anzustreben, daß Ströme über 500 mA bei einer 12 V Bordnetzspannung übertragen werden. Dies bewirkt auch gleichzeitig einen Kontaktreinigungseffekt. Der Metallstab, den der Haken umfaßt, weist eine Kontaktfläche dabei auf dessen geschützter Unterseite auf. Ansonsten ist der Metallstab isoliert. Die Kontaktfläche des Hakens wird dann bei der Befestigung genau auf der Kontaktfläche des Metallstabs liegen. Durch die Befestigungseinrichtung wird dafür gesorgt, dass die Kontaktflächen fest aufeinander zu liegen kommen. Als Kontaktflächen- bzw. Kontaktbasismaterialien eignen sich diejenigen, die auch für Hochstromrelaiskontakte verwendet werden, bspw. Kupfernickel als Grundauflage und als Kontakt Nickel/Silber, sowie als KontaktierungsSchicht Gold. Auch Verbindungen aus Gold, Zinn und Sauerstoff sind hier einsetzbar.Due to the large area, it is then possible to transmit relatively high electrical energies. The aim is to transmit currents above 500 mA at a 12 V vehicle electrical system voltage. This also causes a contact cleaning effect. The metal rod, which the hook comprises, has a contact surface on its protected underside. Otherwise the metal rod is insulated. The contact surface of the hook will then lie exactly on the contact surface of the metal rod during attachment. The fastening device ensures that the contact surfaces come to rest firmly on one another. Suitable contact surface or contact base materials are those which are also used for high-current relay contacts, for example copper nickel as a base and as a contact nickel / silver, and as a contacting layer gold. Compounds made of gold, tin and oxygen can also be used here.
Einer der Haken ist dann für die Masseverbindung vorgesehen, während der andere Haken für die VersorgungsSpannung dient. Der Haken, der für die Masse verwendet wird, ist dann bspw. mit einem Kabel verbunden und zu den einzelnen Verbrauchern im Fahrzeugsitz geführt.One of the hooks is then provided for the ground connection, while the other hook is used for the supply voltage. The hook that is used for the mass is then, for example. connected with a cable and led to the individual consumers in the vehicle seat.

Ausführungsbeispiel des erfindungsgemäßen Fahrzeugsitzes. Eine Sitzfläche 1 des Fahrzeugsitzes weist eine Elektronik 5 auf, die elektrisch mit einer Befestigungsvorrichtung 3 verbunden ist. Die Befestigungsvorrichtung 3 dient zum Ein- und Ausbau des Sitzes .Embodiment of the vehicle seat according to the invention. A seat 1 of the vehicle seat has electronics 5, which is electrically connected to a fastening device 3. The fastening device 3 is used for installing and removing the seat.
Weiterhin ist die Elektronik 5 mit einer Sende- Empfangsstation 7 und einer weiteren Elektronik 8 in der Rückenlehne 2 des Fahrzeugsitzes verbunden. Die Sende- Empfangsstation 7 ist über einen Datenein-/-ausgang mit einer Antenne 30 verbunden, die zum Senden und Empfangen dient. Mit der Sende-/-Empfangsstation 7 werden Daten mit einem hier nicht dargestellten zentralen Steuergerät im Fahrzeug, das bspw. auf dem Fahrzeugtunnel untergebracht ist, ausgetauscht. Über die Elektronik 5 werden die Sende- E pfangsstationen 7 und die Elektronik 8 mit elektrischer Energie über die Befestigungsvorrichtung 3 versorgt. Die Elektronik 5 ist hier ein Steuergerät mit einem Sitzbelegungssensor, um zu erkennen, ob sich eine Person auf dem Sitz befindet. Die Elektronik 8 ist hier eine Zündmittelansteuerung für einen Seitenairbag, der bei einem Seitenaufprall ausgelöst wird. Der Auslösebefehl wird hier vom zentralen Steuergerät zur Antenne 30 und der Sende- Empfangsstation 7 übertragen.Furthermore, the electronics 5 is connected to a transceiver station 7 and further electronics 8 in the backrest 2 of the vehicle seat. The transceiver station 7 is connected via a data input / output to an antenna 30 which is used for transmitting and receiving. The transmitting / receiving station 7 is used to exchange data with a central control unit in the vehicle, not shown here, which is accommodated, for example, on the vehicle tunnel. Via the electronics 5, the transmitting and receiving stations 7 and the electronics 8 are supplied with electrical energy via the fastening device 3. The electronics 5 is here a control unit with a seat occupancy sensor in order to recognize whether a person is on the seat. The electronics 8 here are an ignition means control for a side airbag, which is triggered in the event of a side impact. The trigger command is transmitted from the central control unit to the antenna 30 and the transceiver 7.
Die Befestigungsvorrichtung 3 ist wie später dargestellt hier durch Haken und sogenannte Klammerhaken realisiert, die Metallrohre der Fahrzeugkarosserie umfassen, um mit dem Fahrzeug fest verbunden zu werden. Es sind jedoch auch andere Befestigungsvorrichtungen möglich. Die Klammerhaken sind derzeit bei verschiedenen Fahrzeugherstellern prinzipiell ähnlich. Fig. 4a und 4b zeigen schematisch wie diese Befestigung beim VW Sheran aussieht, die auch beim Seat Alhambra, dem Ford Galaxy, dem Fiat Ulysses und dem Peugeot 806 verwendet wird. Fig. 4a stellt die vordere SitzVerankerung dar und Fig. 4b die hintere SitzVerankerung.The fastening device 3, as shown later, is realized here by hooks and so-called clip hooks, which comprise metal pipes of the vehicle body in order to be firmly connected to the vehicle. However, other fastening devices are also possible. The clip hooks are currently basically similar at different vehicle manufacturers. 4a and 4b show schematically how this attachment looks on the VW Sheran, which is also used on the Seat Alhambra, the Ford Galaxy, the Fiat Ulysses and the Peugeot 806. FIG. 4a shows the front seat anchorage and FIG. 4b the rear seat anchorage.
In Fig. 4a ist dargestellt, wie ein Klammerhaken 40 in den Fahrzeugboden 41 eingelassen wird, um einen Metallstab 42 zu umfassen. Gegen einen weiteren Metallstab 43 ist ein Abstützteil 44 angeordnet, um für Kräfte in Fahrtrichtung 45 •als Crashverzögerung zu wirken. Der Klammerhaken 40 dreht sich um die Drehachse 46. Ein Ausklinkmechanismus 47 und eine Feder 48, die am oberen Hebel des Klammerhakens 40 angeordnet sind, sorgen für die Verriegelung. Beim Ausbau des Fahrzeugsitzes muß man über einen Griff in einem Zugband den Sitz gegen die Federkraft zuerst hinten entriegeln, den Sitz hinten hochklappen und dann das vordere Hebelwerk betätigen, um die Vorderklinken 47 zu lösen.FIG. 4 a shows how a clamp hook 40 is inserted into the vehicle floor 41 in order to enclose a metal rod 42. A support part 44 is arranged against a further metal rod 43 in order to act as a deceleration for forces in the direction of travel 45. The clamp hook 40 rotates about the axis of rotation 46. A release mechanism 47 and a spring 48, which are arranged on the upper lever of the clamp hook 40, ensure the locking. When removing the vehicle seat, one must first unlock the seat against the spring force at the rear using a handle in a drawstring, fold up the seat at the rear and then operate the front lever mechanism to release the front pawls 47.
Fig. 4b zeigt die hintere Sitzverrastung. Ein Abstützteil 50 ist hier vor einem Metallstab 51 angeordnet, der von einem Klammerhaken 52 im eingebauten Zustand umfaßt wird. Das Abstützteil 50 hat auch die Funktion, bei einem Crash als mechanisches Verzögerungsglied zu wirken. Ein weiterer Metallstab 53 wird nur bei gedrehtem Sitz benutzt. Der Klammerhaken weist wiederum eine Drehachse 54 auf und ist mit einem Ausklinkmechanismus 55 und einer Feder 56 verbunden .Fig. 4b shows the rear seat latch. A support part 50 is here arranged in front of a metal rod 51, which is enclosed by a clip hook 52 in the installed state. The support part 50 also has the function of acting as a mechanical delay element in the event of a crash. Another metal rod 53 is used only when the seat is rotated. The clamp hook in turn has an axis of rotation 54 and is connected to a release mechanism 55 and a spring 56.
Auf einer Fahrzeugkarosserie 4 wird dann die Befestigungsvorrichtung 3 realisiert. In der Karosserie 4 befindet sich die Fahrzeugbatterie 6, dessen abgegebene elektrische Energie über die Befestigungsvorrichtung 3 zu der Elektronik 5 gelangt und zur Versorgung der elektrischen und elektronischen Komponenten im Fahrzeugsitz dient. In Figur 1 ist dargestellt, wie ein Klammerhaken als Befestigungsmittel ausgeführt ist. Ein Klammerhaken 9 ist am Sitz befestigt und zwar hier an der Vorderseite 10 des Sitzes .

The clamp hook 9 has contact surfaces 13, which then come into contact with the metal rod 12, so that the electrical connection between the vehicle seat and the vehicle is established.
Der Metallstab 12 ist dabei im Fahrzeugboden befindlich. Hat der Klammerhaken 9 den Metallstab 12 umfaßt,, dann wird ein Mikroschalter 14 betätigt, der anzeigt, daß der Fahrzeugsitz eingebaut ist. Diese Sitzverrastung, die natürlich erst anspricht, wenn alle vorhandenen Mikroschalter eine Verrastung anzeigen, wird zur Sitzeinbauerkennung verwendet.The metal rod 12 is located in the vehicle floor. If the hook 9 has the metal rod 12, then a microswitch 14 is actuated, which indicates that the vehicle seat is installed. This seat lock, which of course only responds when all existing microswitches indicate a lock, is used for seat installation detection.
Über die Kontaktflächen 13 und dem Metallstab 12 sowie dem Klammerhaken 9 kann nun elektrische Energie in den Fahrzeugsitz gelangen. Die Metallstäbe sind hier 3 cm lang und ca. 10 mm dick.Electrical energy can now get into the vehicle seat via the contact surfaces 13 and the metal rod 12 and the clamp hook 9. The metal rods are 3 cm long and approx. 10 mm thick.
Figur 2 zeigt eine Ansicht des Fahrzeugsitzes von oben. Der Fahrzeugsitz 40 weist eine Sitzfläche 19 und eine Kopfstütze 21 sowie eine Sitzlehne 20 auf. Im hinteren Bereich der Sitzfläche 19 sind feststehende Haken 16 angebracht, während an der Vorderseite der Sitzfläche 19 Klammerhaken 17 und 18 verwendet werden. Der Klammerhaken 17 wirkt dabei als Masseanschluß, während der Klammerhaken als Plusanschluß, also als Versorgungsanschluß dient. Der Klammerhaken 18 ist dabei isoliert am Sitzmetallgestell angebracht.Figure 2 shows a view of the vehicle seat from above. The vehicle seat 40 has a seat 19 and a headrest 21 and a seat back 20.
