Description

Sicherheitsgurtverschluß mit ausgeleuchteter Bedientaste Seat belt buckle with illuminated control button
B e s c h r e i b u n gDescription
Die Erfindung betrifft einen Sicherheitsgurtverschluß, insbesondere für Kraftfahrzeuge, mit einem Verschlußgehäuse und mit einer Taste zur Betätigung eines im Verschlußgehäuse angeordneten Riegelmechanismus für eine in das Verschlußgehäuse einsteckbare Verschlußzunge, wobei eine Beleuchtung der Taste eingerichtet ist.The invention relates to a seat belt buckle, in particular for motor vehicles, with a buckle housing and with a button for actuating a locking mechanism arranged in the buckle housing for a tongue which can be inserted into the buckle housing, the button being illuminated.
Ein Sicherheitsgurtverschluß mit den vorgenannten Merkmalen ist in der DE 39 04 125 A I beschrieben; hierbei ist eine Lichtquelle beispielsweise in Form einer Leuchtdiode in einem von der Bedientaste entfernt liegenden Bereich des Verschlusses angeordnet und mit der Taste über einen Lichtleitweg aus einem lichtleitenden Material gekoppelt, wobei der Lichtleitweg vorzugsweise aus vorgefertigten, in das Verschlußgehäuse einzusetzenden Materialabschnitten aus einem glasklar-transparenten Material besteht. Bei der bekannten Ausleuchtung der Taste ist bereits eine berührungsfreie Überleitung des Lichtstroms vom Verschlußgehäuse in die Taste ausgebildet.A seat belt buckle with the aforementioned features is described in DE 39 04 125 A I; Here, a light source, for example in the form of a light-emitting diode, is arranged in an area of the closure that is remote from the operating button and is coupled to the button via a light-guiding path made of a light-guiding material, the light-guiding path preferably consisting of prefabricated material sections of a crystal-clear, transparent material that are to be inserted into the lock housing Material exists. In the known illumination of the button, a contact-free transfer of the luminous flux from the closure housing into the button is already formed.
Mit dem bekannten Sicherheitsgurtverschluß ist jedoch noch der Nachteil verbunden, daß sowohl die Anordnung der Lichtquelle als auch des Lichtleitweges entsprechend viel Raum erfordern, insbesondere um einen ausreichenden Lichtstrom bis zu der Taste des Verschlusses zu leiten. Damit baut der bekannte Sicherheitsgurtverschluß entsprechend groß. Als weiterer Nachteil ist die große Anfälligkeit des bekannten Sicherheitsgurtverschlusses gegen Verschmutzung zu nennen, da im Lichtleitweg insgesamt vier Lichtaustritts- bzw. Lichteintrittsflächen angeordnet sind, die innerhalb der Schloßkappen liegen und daher nicht gereinigt werden können.With the known seat belt buckle, however, there is the disadvantage that both the arrangement of the light source and the Lichtleitweges require a corresponding amount of space, in particular to guide a sufficient luminous flux up to the button of the closure. So that the known seat belt buckle builds accordingly large. Another disadvantage is the high susceptibility of the known seat belt buckle to contamination, since a total of four light exit or light entry surfaces are arranged in the light guide path, which lie within the lock caps and therefore cannot be cleaned.
Der Erfindung liegt daher die Aufgabe zugrunde, bei einem Sicherheitsgurtverschluß mit den gattungsgemäßen Merkmalen eine Ausleuchtung der Taste zu verwirklichen, die ohne eine Vergrößerung der Baugröße gegenüber einem Sicherheitsgurtverschluß ohne Beleuchtung zu realisieren ist.The invention is therefore based on the object of realizing illumination of the button in a seat belt buckle with the generic features, which can be achieved without an increase in size compared to a seat belt buckle without lighting.
Die Lösung dieser Aufgabe ergibt sich einschließlich vorteilhafter Ausgestaltungen und Weiterbildungen der Erfindung aus dem Inhalt der Patentansprüche, welche dieser Beschreibung nachgestellt sind.This object is achieved, including advantageous refinements and developments of the invention, from the content of the patent claims, which follow this description.
Die Erfindung sieht in ihrem Grundgedanken vor, daß die Taste an ihrer sichtbaren Frontseite mit einer elektrisch ansteuerbaren Leuchtfolie versehen ist und die für die Versorgung der Leuchtfolie erforderliche elektrische Energie von einer an einem feststehenden Teil des Verschlusses angordneten Energiequelle unter Überbrücjcung eines Luftspaltes kontaktlos auf die Leuchtfolie übertragbar ist. Mit der Erfindung ist der Vorteil verbunden, daß die Leuchtfolie als Lichtquelle praktisch keinen zusätzlichen Platzbedarf erfordert; nach Ausführungsbeispielen der Erfindung ist die Leuchtfolie einschließlich Empfangselektronik entweder in der Taste vergossen, mit dieser umspritzt oder als gesondertes Bauteil mit der Taste verklipst. Eine Leuchtfolie mit entsprechender elektrischer Ansteuerung ist als solche für andere Anwendungsbereiche durchaus bekannt. Auch die Versorgung der Leuchtfolie mit elektrischer Energie erfordert keinen zusätzlichen Bauraum, da die Energiequelle außerhalb des Verschlusses angeordnet sein kann. Da die elektrische Energie kontaktlos von dem feststehenden Teil des Verschlußgehäuses auf die sich bewegende Taste übertragen wird, ist weiterhin ein gutes Dauerlaufverhalten des Verschlusses wie auch eine hinreichende Staub- und Flüssigkeitsverträglichkeit des Verschlusses gegeben, so daß im Gegensatz zu dem Sicherheitsgurtverschluß nach dem Stand der Technik der erfindungsgemäße Sicherheitsgurtverschluß unempfindlich gegen Verschmutzung ist.The basic idea of the invention provides that the button is provided on its visible front side with an electrically controllable luminescent film and the electrical energy required for supplying the luminescent film from an energy source arranged on a fixed part of the closure while bridging an air gap without contact to the luminescent film is transferable. The invention has the advantage that the luminescent film as a light source requires practically no additional space; According to embodiments of the invention, the luminescent film, including the receiving electronics, is either potted in the key, with this molded or clipped as a separate component with the button. A luminous film with corresponding electrical control is well known as such for other areas of application. The supply of electrical energy to the luminescent film does not require any additional installation space either, since the energy source can be arranged outside the closure. Since the electrical energy is transmitted contactlessly from the fixed part of the fastener housing to the moving button, the fastener has good long-term behavior as well as adequate dust and liquid compatibility, so that, in contrast to the seat belt fastener according to the prior art the seat belt buckle according to the invention is insensitive to contamination.
Nach einem Ausführungsbeispiel der Erfindung ist vorgesehen, daß an dem feststehenden Teil des Verschlusses ein an die Energiequelle angeschlossener Sender vorgesehen ist, dem ein an der Taste angebrachter und elektrisch mit der Leuchtfolie verbundener Empfänger zugeordnet ist, wobei Sender und Empfänger jeweils eine, nach einem Ausführungsbeispiel der Erfindung gegebenenfalls auch als Patch- Antenne ausgebildete Antennen aufweisen können. Alternativ können auch weitere Antennenformen wie Dipolantennen, Wendelantennen, Staboder Hornantennen eingesetzt werden.According to one embodiment of the invention, it is provided that a transmitter connected to the energy source is provided on the fixed part of the closure, to which a receiver attached to the button and electrically connected to the luminous film is assigned, the transmitter and receiver each having one, according to one embodiment the invention may also have antennas designed as patch antennas. Alternatively, other antenna shapes such as dipole antennas, helical antennas, rod or horn antennas can also be used.
In einer alternativen Ausführungsform ist vorgesehen, daß zur kontaktlosen Energieübertragung an dem feststehenden Teil des Verschlusses und an der Taste jeweils eine Spule vorgesehen ist. Hierbei kann vorgesehen sein, daß zwischen Energiequelle und der an dem feststehenden Verschlußteil angeordneten Spule ein Treiber angeordnet ist, wobei dem Treiber noch ein Verstärker nachgeordnet sein kann.In an alternative embodiment it is provided that a coil is provided for the contactless energy transmission on the fixed part of the closure and on the button. It can be provided that between the energy source and the fixed breech arranged coil a driver is arranged, wherein the driver can be followed by an amplifier.
Nach Ausführungsbeispielen der Erfindung ist das feststehende Teil des Verschlusses entweder das die Verschlußzunge aufnehmende Verschlußgehäuse oder aber die das Verschlußgehäuse umschließende Verschlußkappe, und zwar in der Form als gemeinsam das Verschlußgehäuse bildende obere Verschlußkappe oder untere Verschlußkappe.According to embodiments of the invention, the fixed part of the closure is either the closure housing receiving the closure tongue or the closure cap enclosing the closure housing, specifically in the form of an upper closure cap or lower closure cap forming the closure housing.

Der in Figur 1 dargestellte Sicherheitsgurtverschluß 10 besteht aus einem Verschlußgehäuse 16, welches von einer oberen Gehäusekappe 1 1 und einer nicht dargestellten, unteren Gehäusekappe abgedeckt bzw. umschlossen ist. Am hinteren Ende des Sicherheitsgurtverschlusses ist ein Steckverbinder 12 vorgesehen, über den ein elektrischer Anschluß an eine Energiequelle bzw. eine Steuereinheit gegeben ist.The seat belt buckle 10 shown in Figure 1 consists of a buckle housing 16 which is covered or enclosed by an upper housing cap 11 and a lower housing cap, not shown. At the rear end of the seat belt buckle a connector 12 is provided, via which an electrical connection to an energy source or a control unit is provided.
Wie sich im einzelnen aus Figur 2 entnehmen läßt, weist der Sicherheitsgurtverschluß 10 eine in das Verschlußgehäuse 16 einschiebbare Taste 13 auf, wobei zwischen Verschlußgehäuse 16 und der dieses umschließenden Gehäusekappe 11 ein Einschubweg 14 für die Taste 13 ausgespart ist. Der Taste 13 gegenüberliegend ist an dem Verschlußgehäuse 16 ein Halteseil 15 befestigt, mittels dessen der Verschluß 10 an einem Teil des Kraftfahrzeuges befestigbar ist. Alternativ zum Halteseil kann auch ein starrer Verschlußhalter vorgesehen sein. Weiterhin ist mit 17 in dem Verschlußgehäuse 16 ein Riegelmechanismus bezeichnet, der in an sich bekannter Weise mit einer in den Sicherheitsgurtverschluß 10 einsteckbaren, nicht dargestellten Verschlußzunge zusammenwirkt und diese verriegelt; beim Einschieben in den Verschluß 10 wirkt die Taste 13 ebenfalls mit dem Riegelmechanismus 17 in an sich bekannter Weise zusammen, so daß durch das Einschieben der Taste 13 die Verschlußzunge wieder freigegeben wird.As can be seen in detail from FIG. 2, the seat belt buckle 10 has a button 13 which can be inserted into the buckle housing 16, an insertion path 14 for the button 13 being left out between the buckle housing 16 and the housing cap 11 surrounding it. Opposite the button 13, a tether 15 is fastened to the fastener housing 16, by means of which the fastener 10 can be fastened to a part of the motor vehicle. As an alternative to the tether, a rigid closure holder can also be provided. Furthermore, 17 in the fastener housing 16 denotes a locking mechanism which interacts and locks in a manner known per se with a fastener tongue (not shown) which can be inserted into the seat belt fastener 10; when inserted into the closure 10, the key 13 also interacts with the locking mechanism 17 in a manner known per se, so that the closure tongue is released again by inserting the key 13.
Zur Ausleuchtung der Taste 13 ist an der Taste 13 eine elektrisch ansteuerbare Leuchtfolie angebracht, und zwar beispielsweise in der Taste 13 vergossen, mit dieser umspritzt, oder als gesondertes Bauteil mit dieser verklipst. Von der Leuchtfolie 22 führt eine K.abelverbindung 21 zu einem seitwärts, in paralleler Ausrichtung zur Außenkante der Gehäusekappe 1 1 angeordneten Empfänger 20.To illuminate the button 13, an electrically controllable luminescent film is attached to the button 13, for example cast in the button 13, overmolded with it, or clipped onto it as a separate component. A cable connection 21 leads from the luminous film 22 to a receiver 20 which is arranged sideways and in parallel alignment with the outer edge of the housing cap 11.
Dem Empfänger 20 gegenüberliegend ist an der Innenseite der Gehäusekappe 1 1 ein Sender 18 angebracht, der über eine Kabelverbindung 19 mit dem Steckverbinder 12 verbunden ist, so daß über den Steckverbinder 12 eine entsprechende Energieversorgung erfolgen kann. Die über den Steckverbinder 12 und die Kabelverbindung 19 herangeführte elektrische Energie wird von dem Sender 18 berührungslos auf den Empfänger 20 übertragen, so daß die Leuchtfolie 22 angesteuert wird.Opposite the receiver 20, a transmitter 18 is attached to the inside of the housing cap 11, which has a Cable connection 19 is connected to the connector 12 so that a corresponding power supply can take place via the connector 12. The electrical energy supplied via the plug connector 12 and the cable connection 19 is transmitted from the transmitter 18 to the receiver 20 without contact, so that the luminous film 22 is activated.
Entsprechend dem in Figur 2 dargestellten Ausführungsbeispiel zeigt Figur 3 die entsprechende Schaltung mit der Energiequelle 25 und dem an der Gehäusekappe angebrachten Sender 18, dem eine Antenne 26 zugeordnet ist. Tastenseitig ist eine weitere Antenne 27 vorgesehen, die mit dem Empfänger 20 verbunden ist, der seinerseits über die Kabelverbindung 21 an die Leuchtfolie 22 angeschlossen ist.According to the exemplary embodiment shown in FIG. 2, FIG. 3 shows the corresponding circuit with the energy source 25 and the transmitter 18 attached to the housing cap, to which an antenna 26 is assigned. A further antenna 27 is provided on the button side and is connected to the receiver 20, which in turn is connected to the luminous film 22 via the cable connection 21.
In einer alternativen Schaltung weist die gehäuseseitig ausgebildete Energieversorgung die Energiequelle 25 mit einem nachgeschalteten Treiber 28 auf, dem eine gehäuseseitige Spule 29 zugeschaltet ist. Der Spule 29 ist eine an der Taste 13 befindliche Spule 30 zugeordnet, die über die Kabelverbindung 21 mit der Leuchtfolie 22 verbunden ist.In an alternative circuit, the energy supply formed on the housing side has the energy source 25 with a downstream driver 28, to which a coil 29 on the housing side is connected. The coil 29 is assigned a coil 30 located on the button 13, which is connected to the luminous film 22 via the cable connection 21.
