Description

System zur elektrischen Verbindung eines Sitzes, insbesondere eines Fahrzeugsitzes System for the electrical connection of a seat, in particular a vehicle seat
Die Erfindung betrifft ein System zur elektrischen Verbindung eines Sitzes, insbesondere eines Fahrzeugsitzes, nach dem Oberbegriff von Anspruch 1.The invention relates to a system for the electrical connection of a seat, in particular a vehicle seat, according to the preamble of claim 1.
Zur Vergrößerung der Ladeflache eines Fahrzeugs ist es bekannt, Fahrzeugsitze losbar mit dem Fahrzeugboden zu verbinden, wobei diese bei Bedarf auf möglichst einfache Weise ausgebaut werden sollten. Schwierigkeiten treten dabei dann auf, wenn der Sitz mit elektrischen Stromkontaktelementen versehen ist, wie z.B. für eine Sitzheizung, in diesem Falle müssen die Kontakte zu den Stromzufuhrkontakten, welche m oder am Fahrzeugboden angeordnet sind, gelost werden . Neben einem erhöhten Aufwand besteht dabei die Gefahr von Beschädigungen und Verschmutzungen der Stromkontaktelemente, wenn diese offen liegen. Eine weitere Schwierigkeit tritt dann auf, wenn der Sitz zusatzlich noch m Längsrichtung Terfahr- bar sein soll.To enlarge the loading area of a vehicle, it is known to connect vehicle seats to the vehicle floor in a detachable manner, which should be removed in the simplest possible manner if necessary. Difficulties arise when the seat is provided with electrical current contact elements, such as for a seat heater, in this case the contacts to the power supply contacts, which are located m or on the vehicle floor, must be disconnected. In addition to increased effort, there is a risk of damage and soiling of the current contact elements if they are exposed. Another difficulty arises when the seat is also supposed to be movable in the longitudinal direction.
Zum allgemeinen Stand der Technik wird auf die EP 0 605 260 Bl verwiesen.Regarding the general state of the art, reference is made to EP 0 605 260 B1.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung bzw. ein System zu schaffen, mit welchem eine elektrische Verbindung zwischen einem Sitz und einer Bodenkontakteinrichtung geschaffen werden kann, welche auf einfache Weise gelost und auch wieder verbunden werden kann, wobei so weit wie möglich auch Beschädigungen und Verschmutzungen der Stromkontaktelemente vermieden werden sollen.The present invention is therefore based on the object of creating a device or a system with which an electrical connection between a seat and a floor contact device can be created, which can be detached and reconnected in a simple manner, damage and soiling of the current contact elements should be avoided as far as possible.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass das Befestigungsglied ein mit Stromkontaktelementeή versehenen Stempel aufweist, und dass die Bodenkontakteinrichtung eine mit Stromkontaktelementen versehene drehbare Kontaktbrücke aufweist, wobei zur elektrischen Verbindung des Sitzes mit der Bodenkontakteinrichtung der Stempel die Kontaktbrücke in eine Stellung dreht, in der sich die Stromkontaktelemente des Stempels und die Stromkontaktelemente der Kontaktbrücke kontaktieren. Die Drehung der Kontaktbrücke erfolgt vorzugsweise gegen eine Rückhalteeinrichtung.According to the invention, this object is achieved in that the fastening member has a stamp provided with current contact elements, and that the floor contact device has a rotatable contact bridge provided with current contact elements, the contact bridge rotating into a position in which the stamp rotates for electrical connection of the seat to the floor contact device contact the current contact elements of the stamp and the current contact elements of the contact bridge. The contact bridge is preferably rotated against a retaining device.
Durch die erfindungsgemäße Kontaktbrücke, an der die Stromkontaktelemente angeordnet sind, wird zum einen eine schnelle Lösbarkeit und Wiederverbindbarkeit geschaffen und zum anderen können die Stromkontaktelemente durch eine entsprechende Verdrehung der Strombrücke in eine Position gebracht werden, in der sie vor Beschädigungen oder auch vor Verschmutzung geschützt werden können. Durch den an einem Sitzgestellteil angeordneten Stempel kann automatisch beim Aufsetzen des Sitzes die Kontaktbrücke in eine Position gedreht werden, in der sich die Kontaktflächen der beiderseitigen Elemente kontaktieren.The contact bridge according to the invention, on which the current contact elements are arranged, on the one hand provides quick detachability and reconnectability and, on the other hand, the current contact elements can be brought into a position by correspondingly rotating the current bridge, in which they are protected against damage or contamination can. By means of the stamp arranged on a seat frame part, the contact bridge can be automatically rotated when the seat is placed in a position in which the contact surfaces of the elements on both sides contact each other.
Von Vorteil ist es dabei, wenn die Rückhalteeinrichtung eine Federeinrichtung aufweist, die bei abgehobenem Sitz die Kontaktbrücke in einer Position hält bzw. in eine Position bringt, in der eine Abdeckfläche der Kontaktbrücke die Kontaktelemente der Kontaktbrücke abdeckt. Auf diese Weise sind die Stromkontaktelemente sowohl vor Beschädigung als auch vor Verschmutzung geschützt. Dies ist insbesondere dann der Fall, wenn die Abdeckfläche wenigstens annähernd bündig mit der Bodenfläche des Bodens ist. In diesem Falle sind die Stromkontaktelemente geschützt unter der Abdeckfläche im Boden, wozu dieser eine entsprechende Aussparung aufweisen sollte.It is advantageous if the retaining device has a spring device which, when the seat is lifted off, holds the contact bridge in a position or brings it into a position in which a cover surface of the contact bridge covers the contact elements of the contact bridge. In this way, the current contact elements are protected both from damage and from contamination. This is particularly the case when the cover surface is at least approximately flush with the bottom surface of the floor. In this case, the current contact elements are protected under the cover surface in the floor, for which purpose this should have a corresponding recess.
Neben der Schutzwirkung durch die erfindungsgemäße Vorrichtung bzw. das erfindungsgemäße System für die Stromkontaktelemente besteht ein weiterer Vorteil darin, dass durch die drehbare Kontaktbrücke mit ihren Stromkontaktelementen bei der Verbindung mit den Stromkontaktelementen des Stempels und auch von Stromzufuhrkontaktelementen, die in der Bodenkontakteinrichtung angeordnet sind, bei deren Kontaktierung eine Gleitreibung entsteht, durch die die Kontaktflächen von Verschmutzungen und/oder Oxidierungen freigehalten werden. Auf diese Weise ist stets ein sehr guter Kontakt mit einer großen Kontaktfläche vorhanden, wodurch sich über die Stromkontaktelemente auch hohe Amperezahlen übertragen lassen. Die Praxis hat gezeigt, dass sich auf diese Weise 20 und mehr Ampere übertragen lassen. Je nach Ausgestaltung der Kontur der Stromkontaktelemente und eines entsprechenden Anpressdruckes kann die Reibung und damit auch die übertragbare Amperezahl erhöht werden.In addition to the protective effect of the device according to the invention or the system according to the invention for the current contact elements, a further advantage is that the rotatable contact bridge with its current contact elements when connected to the current contact elements of the stamp and also from current supply contact elements which are arranged in the ground contact device the contacting creates a sliding friction, through which the contact surfaces are kept free from dirt and / or oxidation. In this way, there is always very good contact with a large contact area, as a result of which high amperages can also be transmitted via the current contact elements. Practice has shown that 20 and more amperes can be transmitted in this way. Depending on the design of the contour of the current contact elements and a corresponding contact pressure, the friction and thus also the transferable amperage can be increased.
Der Anpressdruck der Stromkontaktelemente der Kontaktbrücke an die Stromkontaktelemente des Stempels und der Stromzufuhrkontaktelemente lässt sich durch Anpressglieder verstärken, die z.B. in einem Spalt zwischen den auf der Rückseite in Bogenform ausgeführten Stromkontaktelementen und einer bogenförmigen Lagerung eingelegt sind. Die erfindungsgemäße elektrische Verbindung lässt sich auch auf einfache Weise bei Sitzen realisieren, die zusätzlich auch noch in Längsrichtung, d.h. in Fahrzeugrichtung, verschiebbar sind.The contact pressure of the current contact elements of the contact bridge against the current contact elements of the stamp and the current supply contact elements can be increased by pressure elements which are inserted, for example, in a gap between the current contact elements embodied in an arc shape on the back and an arcuate bearing. The electrical connection according to the invention can also be implemented in a simple manner in the case of seats which can also be displaced in the longitudinal direction, ie in the vehicle direction.
Hierzu ist es in einer Ausgestaltung der Erfindung lediglich erforderlich, dass das Befestigungsglied mit dem Stempel und die Sitzschiene über Verbindungsglieder derart verbindbar sind, dass eine entsprechende Längsverschiebung zwischen den beiden Teilen möglich wird.For this purpose, it is only necessary in one embodiment of the invention that the fastening member can be connected to the stamp and the seat rail via connecting members in such a way that a corresponding longitudinal displacement between the two parts is possible.
Dies kann z.B. in einer vorteilhaften Ausgestaltung dadurch erfolgen, dass entweder die Sitzschiene oder der Stempel mit einer Längsnut versehen sind und dann das entsprechende Gegenstück mit einem Gleitglied versehen wird, das in der Längsnut verschiebbar ist.This can e.g. In an advantageous embodiment, this is done in that either the seat rail or the punch are provided with a longitudinal groove and then the corresponding counterpart is provided with a sliding member which is displaceable in the longitudinal groove.
Damit die Stabilität der Sitzschiene nicht beeinträchtigt wird, wird man im allgemeinen das Gleitglied bzw. eine entsprechende Gleitschiene an der Sitzschiene befestigen, das bzw. die dann in einer Schwalbenschwanzführung oder einer T- Nutführung des Stempels zur Längsverschiebbarkeit der Sitzschiene geführt ist.So that the stability of the seat rail is not impaired, the slide member or a corresponding slide rail is generally attached to the seat rail, which is then guided in a dovetail guide or a T-slot guide of the plunger for the longitudinal displacement of the seat rail.
Da im allgemeinen der Sitz beim Lösen und beim Wiederverbinden in einer Schwenkbewegung nach oben oder unten geklappt wird, ist in einer vorteilhaften Weiterbildung der Erfindung vorgesehen, dass der Stempel mit einem Anbindungsteil versehen ist, welches gegenüber dem Stempel um eine horizontale Achse drehbar ist. In diesem Falle stellt das Anbindungsteil die Verbindung zu der Sitzschiene her und kann auf diese Weise entsprechend auf den Radius der Schwenkbewegung eingestellt werden bzw. sich gegenüber dem Stempel entsprechend verdrehen. In diesem Fall wird man die Längsnut in das Anbindungsteil einbringen.Since in general the seat is pivoted upwards or downwards when loosening and reconnecting, it is provided in an advantageous development of the invention that the stamp is provided with a connecting part which can be rotated about a horizontal axis relative to the stamp. In this case, the connecting part establishes the connection to the seat rail and can be connected to it Set accordingly to the radius of the pivoting movement or twist accordingly with respect to the punch. In this case, the longitudinal groove will be made in the connecting part.
Vorteilhafte Weiterbildungen und Ausgestaltungen ergeben sich aus den übrigen ünteransprüchen und aus dem nachfolgend anhand der Zeichnung prinzipmäßig beschriebenen Ausführungsbeispiel .Advantageous further developments and refinements result from the remaining subclaims and from the exemplary embodiment described in principle below with reference to the drawing.

Das System bzw. die Vorrichtung zur elektrischen Verbindung eines Sitzes 1, der aus Übersichtlichkeitsgründen nur in der Fig. 1 ausschnittsweise dargestellt ist, weist ein Befestigungsglied 2 mit einem Stempel 3 auf, in dem eine Vielzahl von nebeneinander angeordneten Stromkontaktelementen 4 angeordnet sind. Von den Stromkontaktelementen 4 führen in nicht näher dargestellter Weise Leitungen 5 zu im Sitz 1 angeordneten Stromverbrauchern. Wie ersichtlich, ragt der Stempel 3 von dem Sitz 1 aus nach unten über die Stromkontaktelemente 4 hinaus und stellt damit gleichzeitig auch eine Schutz- schürze für die Stromkontaktelemente 4 dar. In dem unter dem Stempel 3 angeordneten Fahrzeugbereich befindet sich im Boden 6 des Fahrzeuges eine Bodenkontakteinrichtung 7 mit einem Gehäuse 7a mit einem freien Innenraum 8. In dem freien Innenraum 8 ist eine Kontaktbrucke 9 m Form einer Kontaktwalze drehbar angeordnet. Hierzu besitzt sie auf beiden Stirnseiten Drehzapfen 10, welche im Boden 6 bzw. dem Gehäuse 7a gelagert s nd. Die Kontaktbrucke 9 weist eine Vielzahl von nebeneinander angeordneten Schlitzen m Bogenform auf, in die Stromkontaktelemente 11 eingelegt sind, welche auf ihrer Ruckseite eine Bogenform aufweisen, die den gleichen Radius besitzt wie die Bogenform der Schlitze m der Kontaktbrucke 9. Jedes Stromkontaktelement 11 besitzt zwei Kontaktflachen, nämlich eine erste Eingangsstromkontaktflache 12 und eine zweite Stromkontaktflache 13, welche bei Durchfuhrung der elektrischen Verbindung eine Stromkontaktflache 14 des zugehörigen Stromkontaktelementes 4 des Stempels 3 kontaktiert. Beide Stromkontaktflachen 13 und 14 besitzen eine gekrümmte Form, welche zur Herstellung eines großen Flachenkontaktes m ihrem Verlauf aneinander angepasst sind, wozu eine Kontaktflache konkav und die andere Kontaktflache entsprechend konvex ausgebildet ist.The system or the device for the electrical connection of a seat 1, which is only shown in detail in FIG. 1 for reasons of clarity, has a fastening member 2 with a stamp 3, in which a multiplicity of current contact elements 4 arranged next to one another are arranged. Cables 5 lead from the current contact elements 4 to current consumers arranged in the seat 1 in a manner not shown. As can be seen, the stamp 3 protrudes downward from the seat 1 beyond the current contact elements 4 and at the same time also provides a protective apron for the current contact elements 4. In the vehicle area arranged under the stamp 3 there is in the floor 6 of the vehicle a floor contact device 7 with a housing 7a with a free interior 8. In the free interior 8 a contact bridge 9 m in the form of a contact roller is rotatably arranged , For this purpose, it has pivots 10 on both end faces, which are mounted in the base 6 or the housing 7a. The contact bridge 9 has a large number of slits arranged in an arc shape, into which current contact elements 11 are inserted, which have an arc shape on their rear side , which has the same radius as the arc shape of the slots m of the contact bridge 9. Each current contact element 11 has two contact surfaces, namely a first input current contact surface 12 and a second current contact surface 13, which, when carrying out the electrical connection, has a current contact surface 14 of the associated current contact element 4 of the stamp 3 contacted. Both current contact surfaces 13 and 14 have a curved shape, which are adapted to one another in order to produce a large surface contact, for which purpose one contact surface is concave and the other contact surface is correspondingly convex.
Gleiches gilt jeweils für die Eingangsstromkontaktflachen 12, welche im Verbmdungszustand mit Stromzufuhrungskontakt- elementen 15 m Kontakt treten, die sich m dem Gehäuse 7a befinden. Die Eingangsstromkontaktflachen 12 besitzen eine Bogenform, an die die Kontaktflachen der Stro zufuhrungskon- taktelemente 15 komplementär bzw. m negativer Form angepasst sind. Zu den Stromzufuhrungskontaktelementen 15 fuhren elektrische Leitungen 16 (siehe Fig. 1) . Wie insbesondere aus der perspektivischen Ansicht gemäß Fig. 4 ersichtlich ist, können auf diese Weise eine Vielzahl von Stromkontaktelementen 11 auf Abstand nebeneinander und parallel zueinander angeordnet sein, welche mit einer entsprechenden Anzahl von Stromkontaktelementen 4 in dem Stempel 3 und von Stromzufuhrkontaktelementen 15 im Gehäuse 7a verbindbar sind. Auf diese Weise lassen sich eine Vielzahl von elektrischen Verbrauchern, die in dem Sitz 1 angeordnet sind, mit Strom versorgen.The same applies in each case to the input current contact surfaces 12 which, in the connected state, come into contact with current supply contact elements 15 m which are located in the housing 7 a. The input current contact surfaces 12 have an arc shape to which the contact surfaces of the power supply contact elements 15 are matched in a complementary or m negative form. Electrical lines 16 lead to the power supply contact elements 15 (see FIG. 1). As can be seen in particular from the perspective view according to FIG. 4, a plurality of current contact elements 11 can be arranged at a distance next to one another and parallel to one another, which have a corresponding number of current contact elements 4 in the stamp 3 and of current supply contact elements 15 in the housing 7a are connectable. In this way, a large number of electrical consumers which are arranged in the seat 1 can be supplied with electricity.
Aus der Fig. 1 und auch aus der Fig. 5 ist ersichtlich, dass die Kontaktbrücke 9 bzw. die Kontaktwalze auf der von den Stromkontaktelementen 11 abgewandten Rückseite eine ebene Abdeckfläche 17 aufweist, welche bei abgehobenem Sitz 1 bündig mit dem Boden 6 ist. Wie ersichtlich, ist damit nicht nur eine ebene Ladefläche geschaffen, sondern darüber hinaus sind auch die Stromkontaktelemente 11 und auch die Stromzufuhrkontaktelemente 15 auf diese Weise vor Verschmutzung und vor Beschädigung geschützt. Zur Lagefixierung der Stromkontaktelemente 11 sind diese mit einer nutartigen Aussparung 18 versehen, in die eine Nase oder Versteifungsrippen 19 ragt, welche mit der Kontaktbrücke 9 verbindbar ist. Auf diese Weise lassen sich die Stromkontaktelemente 11 in die Schlitze der Kontaktbrücke 9 einlegen und auch entsprechend positionieren.From FIG. 1 and also from FIG. 5 it can be seen that the contact bridge 9 or the contact roller on the back facing away from the current contact elements 11 has a flat cover surface 17 which is flush with the floor 6 when the seat 1 is lifted off. As can be seen, this not only creates a flat loading surface, it also protects the current contact elements 11 and also the current supply contact elements 15 from soiling and damage. To fix the position of the current contact elements 11, they are provided with a groove-like recess 18 into which a nose or stiffening ribs 19 projects, which can be connected to the contact bridge 9. In this way, the current contact elements 11 can be inserted into the slots of the contact bridge 9 and also positioned accordingly.
Der elektrische Verbindungsvorgang zwischen dem Sitz 1 und der Bodenkontakteinrichtung 7 ist aus den Figuren 1 bis 3 ersichtlich. Fig. 1 zeigt die Position kurz vor der Verbindung. Wie ersichtlich, greift der Stempel 3 seitlich versetzt bzw. neben der Drehachse der Lagerzapfen 10 an bzw. trifft asymmetrisch auf die Abdeckfläche 17 der Kontaktwalze 9.The electrical connection process between the seat 1 and the ground contact device 7 can be seen from FIGS. 1 to 3. Fig. 1 shows the position shortly before the connection. As can be seen, the punch 3 engages laterally offset or next to the axis of rotation of the bearing pin 10 strikes the cover surface 17 of the contact roller 9 asymmetrically.
Beim weiteren Absenken des Sitzes 1 drückt der Stempel 3 somit asymmetrisch auf die Abdeckfläche 17 der Kontaktbrücke 9 und verdreht diese deshalb in Pfeilrichtung (siehe Fig. 2) . Bei dieser Drehbewegung werden auch die Kontaktflächen 12 und 13 der Stromkontaktelemente 11 entsprechend mitverdreht, so dass sie während des Drehvorganges zunehmend in Kontakt mit den Kontaktflächen 14 der Stromkontaktelemente 4 des Stempels 3 und mit den Stromzufuhrkontaktelementen 15 geraten. Nach einer Verdrehung um 90° (siehe Fig. 3) ist der e- lektrische Verbindungsvorgang beendet und es liegen großflächige Kontakte zwischen den einzelnen Stromkontaktelementen vor. Hierzu sind die gekrümmten bzw. gebogenen Flächen der Stromkontaktelemente aller Teile entsprechend aneinander jeweils in positiver und negativer Form angepasst.When the seat 1 is lowered further, the plunger 3 thus presses asymmetrically on the cover surface 17 of the contact bridge 9 and therefore rotates it in the direction of the arrow (see FIG. 2). During this rotational movement, the contact surfaces 12 and 13 of the current contact elements 11 are also rotated accordingly, so that they increasingly come into contact with the contact surfaces 14 of the current contact elements 4 of the stamp 3 and with the current supply contact elements 15 during the turning process. After a rotation of 90 ° (see FIG. 3), the electrical connection process has ended and there are large-area contacts between the individual current contact elements. For this purpose, the curved or curved surfaces of the current contact elements of all parts are matched to one another in a positive and negative form.
Die elektrischer Verbindung des Sitzes 1 mit den Stromzufuhrkontaktelementen 15, die in dem Boden 6 bzw. der Bodenkontakteinrichtung 7 angeordnet sind, erfolgt entgegen einer Rückhalteeinrichtung, die durch eine Federeinrichtung mit zwei Federn 20 gebildet ist, die sich auf den Lagerzapfen 10 der Kontaktbrücke 9 befinden. Die Federn 20 erzeugen eine Schwenkkraft auf die Kontaktbrücke in Richtung auf eine Stellung entgegen der Pfeilrichtung gemäß Fig. 2, wodurch die Abdeckfläche 17 mit dem Boden 6 bündig ist, wenn der Sitz 1 abgehoben ist. Im Bedarfsfall kann für die Abdeckposition auch ein Anschlag oder eine Raststellung vorgesehen sein. Dies bedeutet, die elektrische Verbindung beim Aufsetzen des Sitzes 1 muss gegen die Rückstellkräfte der beiden Federn 20 erfolgen. Aufgrund des Gewichtes des Sitzes 1 ist jedoch kein besonderer Kraftaufwand hierzu erforderlich. Andererseits hingegen wird nach einem Abheben des Sitzes 1 sicher dafür gesorgt, dass sich die Kontaktbrücke 9 in eine Position dreht, wie aus Fig. 1 ersichtlich, ist die Aussparung 8 in dem Gehäuse 7a durch die Kontaktbrücke 9 abgeschlossen, womit gleichzeitig auch die darunter sich befindlichen Stromkontaktelemente 11 geschützt sind.The electrical connection of the seat 1 to the power supply contact elements 15, which are arranged in the bottom 6 or the bottom contact device 7, takes place against a retaining device which is formed by a spring device with two springs 20 which are located on the bearing journal 10 of the contact bridge 9 , The springs 20 generate a pivoting force on the contact bridge in the direction of a position against the direction of the arrow according to FIG. 2, as a result of which the cover surface 17 is flush with the floor 6 when the seat 1 is lifted off. If necessary, a stop or a locking position can also be provided for the cover position. This means that the electrical connection when placing the seat 1 must be made against the restoring forces of the two springs 20. Due to the weight of the seat 1 is however, no special effort is required. On the other hand, after the seat 1 has been lifted off, it is ensured that the contact bridge 9 rotates into a position, as can be seen in FIG. 1, the recess 8 in the housing 7a is closed by the contact bridge 9, which also means that the one below it current contact elements 11 are protected.
In den Figuren 9 und 10 sind jeweils in vergrößerter Darstellung zwei Ausführungsformen für elastische Anpressglieder dargestellt, die sicherstellen können, dass es bei einer elektrischen Verbindung zu einem einwandfreien Kontakt der zusammenarbeitenden Stromkontaktelemente kommt. Gleichzeitig wird damit auch eine Gleitreibung verstärkt, die für eine Sauberhaltung aller Stromkontaktelemente sorgt. Dies wird noch verstärkt, wenn - wie erwähnt - der Radius des Bogens des Stromkontaktelementes 11 auf der Rückseite dem Radius des Schlitzes in der Kontaktbrücke 9 entspricht, wie dies in der Fig. 9 dargestellt ist. Zwischen dem Stromkontaktelement 11 und dem Lagerbogen der Kontaktbrücke 9 ist ein Umfangs- spalt 21 vorhanden, in welchem mit Abstand voneinander angeordnet zwei elastische Dichtstreifen 22 gemäß Fig. 9 eingelegt sind. Erfolgt nun eine Kontaktierung der Stromkontaktelemente während der Drehbewegung der Kontaktbrücke 9, verbunden mit einer Verkleinerung des Spaltes 21 aufgrund der Elastizität der Dichtstreifen 22, so erfolgt entsprechend eine Verschiebung der Stromkontaktelemente 11 mit einer entsprechenden Verlängerung der Reibbewegung, womit eine noch bessere Reinigungswirkung der Stromkontaktelemente 11 erreicht wird. Anstelle von zwei auf Abstand voneinander angeordneten elastischen Dichtstreifen 22 kann gemäß Fig. 10 auch für jedes Stromkontaktelement 11 in der Kontaktbrücke 9 ein Druckkissen 22a vorgesehen werden, das durch eine auf der Rückseite des Druckkissens 22a in einer Aussparung der Kontaktbrücke 9 angeordnete Feder 23 an den rückwärtigen Bogen des Stromkontaktelementes 11 angepresst wird.FIGS. 9 and 10 each show an enlarged representation of two embodiments for elastic pressing members, which can ensure that the cooperating current contact elements come into perfect contact with an electrical connection. At the same time, this increases sliding friction, which ensures that all current contact elements are kept clean. This is exacerbated if - as mentioned - the radius of the arc of the current contact element 11 on the back corresponds to the radius of the slot in the contact bridge 9, as shown in FIG. 9. Between the current contact element 11 and the bearing arch of the contact bridge 9 there is a circumferential gap 21, in which two elastic sealing strips 22 according to FIG. 9 are placed at a distance from one another. If contact is now made with the current contact elements during the rotary movement of the contact bridge 9, associated with a reduction in the gap 21 due to the elasticity of the sealing strips 22, the current contact elements 11 are correspondingly displaced with a corresponding extension of the frictional movement, which results in an even better cleaning effect of the current contact elements 11 is achieved. Instead of two elastic sealing strips 22 arranged at a distance from one another, a pressure pad 22a can also be provided for each current contact element 11 in the contact bridge 9, as shown in FIG back arc of the current contact element 11 is pressed.
Aus den Figuren 11 und 12 ist eine Ausführungsform für eine elektrische Verbindungsvorrichtung prinzipmäßig dargestellt, die bei einem Sitz 1 eingesetzt werden kann, welcher durch eine Sitzschiene 24 in Fahrzeuglängsrichtung verschiebbar ist. Die Sitzschiene 24 wird hierzu entsprechend in einer Schiene 25 (gestrichelt dargestellt) im Fußboden 6 geführt, wie z.B. durch eine T-Nutform, womit der Sitz 1 in Pfeilrichtung gemäß Fig. 12 verschiebbar ist.FIGS. 11 and 12 show in principle an embodiment for an electrical connection device which can be used in a seat 1 which can be displaced in the longitudinal direction of the vehicle by a seat rail 24. The seat rail 24 is accordingly guided in a rail 25 (shown in dashed lines) in the floor 6, such as by a T-groove shape, with which the seat 1 can be displaced in the direction of the arrow according to FIG. 12.
Durch die Verschiebbarkeit des Sitzes 1 bzw. der damit verbundenen Sitzschiene 24 muss auch eine Verschiebbarkeit zu dem Stempel 3 und der Kontaktbrücke 9 gegeben sein, da diese Teile ja ortsfest für eine elektrische Verbindung verbleiben müssen. Wie aus der Fig. 11 ersichtlich ist, ist hierfür der Stempel 3 mit einem seitlichen Anbindungsteil 2 versehen, in welchem eine in Fahrzeuglängsrichtung verlaufende T-Nut 27 eingebracht ist. In der T-Nut 27 ist ein Gleitglied in Form eines länglichen T-Stückes 28 geführt, das seitlich an der Sitzschiene 24 befestigt ist. Wie aus der Fig. 12 ersichtlich ist, lässt sich auf diese Weise die Sitzschiene 24 und damit auch der Sitz 1 in Pfeilrichtung relativ zu der in Fig. 11 dargestellten Einrichtung mit dem Stempel 3 und der in dem Gehäuse 7a angeordneten Kontaktbrücke 9 verschieben. Um eine einwandfreie elektrische Verbindung zu erreichen und um ein Verklemmen zu vermeiden, kann das Anbindungsteil 26 über eine horizontale Drehachse 29, die in der Fig. 11 gestrichelt angedeutet ist, um eine horizontale Achse drehbar mit dem Stempel 3 verbunden sein. In diesem Falle sind somit Stempel 3 und Anbindungsteil 26 nicht einstückig, sondern - wie gestrichelt dargestellt - zweiteilig ausgebildet, so dass sich eine Schwenkbewegung um die horizontale Achse durchführen lässt. Auf diese Weise ist der Einführvorgang des Stempels 3 während der Schwenkbewegung in das Gehäuse 7a leichter möglich.Due to the displaceability of the seat 1 or the seat rail 24 connected to it, there must also be a displaceability to the stamp 3 and the contact bridge 9, since these parts must remain stationary for an electrical connection. As can be seen from FIG. 11, the stamp 3 is provided with a lateral connecting part 2, in which a T-groove 27 running in the longitudinal direction of the vehicle is introduced. In the T-groove 27, a sliding member in the form of an elongated T-piece 28 is guided, which is attached to the side of the seat rail 24. As can be seen from FIG. 12, the seat rail 24 and thus also the seat 1 can be displaced in the direction of the arrow relative to the device shown in FIG. 11 with the stamp 3 and the contact bridge 9 arranged in the housing 7a. In order to achieve a perfect electrical connection and to avoid jamming, the connecting part 26 can be connected to the plunger 3 via a horizontal axis of rotation 29, which is indicated by dashed lines in FIG. 11, about a horizontal axis. In this case, the punch 3 and the connecting part 26 are not formed in one piece, but rather, as shown in dashed lines, in two parts, so that a pivoting movement about the horizontal axis can be carried out. In this way, the insertion process of the stamp 3 is easier during the pivoting movement into the housing 7a.
Hierzu ist es selbstverständlich auch erforderlich, eine "Nullposition" festzulegen, damit der Stempel 3 positionsgenau über der Bodenkontakteinrichtung 7 liegt und dann eingeführt werden kann.For this purpose, it is of course also necessary to define a "zero position" so that the stamp 3 lies precisely over the ground contact device 7 and can then be inserted.
Selbstverständlich ist der Sitz 1 zusätzlich zu der elektrischen Verbindung - wie dargestellt - noch mechanisch zu arretieren. Derartige mechanische Arretierungen sind jedoch allgemein bekannt, weshalb sie hier nicht näher beschrieben werden. Of course, in addition to the electrical connection, the seat 1 can also be mechanically locked, as shown. However, such mechanical locks are generally known, which is why they are not described in more detail here.
