Abstract

Die Erfindung betrifft ein Kopfstützsystem für einen Fondsitzplatz in einem Fahrzeug und ein Verfahren zu dessen Betrieb. Das Kopfstützsystem umfasst eine automatisch aktivierbare Kopfstütze, mindestens einen Sitzplatzsensor, mittels dessen feststellbar ist, ob der Fondsitzplatz von einem Fahrzeuginsassen besetzt ist, und eine Steuereinheit, der ein Signal des mindestens einen Sitzplatzsensors zuführbar und mittels derer die Kopfstütze in Abhängigkeit von dem Signal des mindestens einen Sitzplatzsensors aktivierbar ist. Die Kopfstütze wird automatisch durch die Steuereinheit aktiviert, wenn von dem mindestens einen Sitzplatzsensor erkannt wird, dass der Frontsitzplatz besetzt wird.The invention relates to a headrest system for a rear seat in a vehicle and a method for its operation. The headrest system comprises an automatically activatable headrest, at least one seat sensor, by means of which it can be determined whether the rear seat is occupied by a vehicle occupant, and a control unit, which can be fed with a signal of the at least one seat sensor and by means of which the headrest in response to the signal of at least a seat sensor is activated. The headrest is automatically activated by the control unit when it is detected by the at least one seat sensor that the front seat is occupied.

Description

Die Erfindung betrifft ein Kopfstützsystem für einen Fondsitzplatz eines Fahrzeuges und ein Verfahren zum dessen Betrieb.The The invention relates to a headrest system for one Rear seat of a vehicle and a method for its operation.

Es ist bekannt, in Kraftfahrzeugen eingesetzte Sitze mit Kopfstützen zu versehen. Eine derartige Kopfstütze dient der Verminderung von Krafteinwirkungen auf die Halswirbelsäule eines Fahrzeuginsassen bei plötzlicher Änderung der Fahrzeugbewegung. Ferner bietet sie einem Fahrzeuginsassen die Möglichkeit, den Kopf an die Kopfstütze anzulehnen.It is known, used in motor vehicles seats with headrests Mistake. Such a headrest is used to reduce the effects of force on the cervical spine Vehicle occupants in case of sudden change the vehicle movement. It also offers a vehicle occupant the opportunity the head to the headrest to lean.

Kopfstützen für Fondsitzplätze, die nicht fest installiert sind, müssen gegenwärtig manuell eingerichtet werden, beispielsweise mittels eines Aufklappmechanismus. Eine derartige manuelle Einrichtung wird von Fahrzeuginsassen jedoch häufig nicht vorgenommen, so dass die Schutzfunktion der Kopfstützen nicht in Anspruch genommen wird. Daraus ergibt sich eine gesundheitliche Gefährdung der Fahrzeuginsassen beispielsweise durch Unfälle oder starke Abbremsung des Kraftfahrzeuges.Headrests for rear seats, the not permanently installed currently be set up manually, for example by means of a folding mechanism. However, such a manual device is used by vehicle occupants often not made, so the protective function of the headrests not is claimed. This results in a health endangering the vehicle occupants, for example, by accidents or severe deceleration of the motor vehicle.

Der Erfindung liegt die Aufgabe zu Grunde, verbesserte Kopfstützen für Fondsitze anzugeben.Of the Invention is based on the object, improved headrests for rear seats specify.

Die Aufgabe wird erfindungsgemäß durch eine Anordnung mit den in Anspruch 1 angegebenen Merkmalen und ein Verfahren mit den in Anspruch 3 angegebenen Merkmalen gelöst.The The object is achieved by a Arrangement with the features specified in claim 1 and a method solved with the features specified in claim 3.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Embodiments of the invention are the subject of the dependent claims.

Die Erfindung sieht ein Kopfstützsystem für einen Fondsitzplatz in einem Fahrzeug vor. Das Kopfstützsystem umfasst eine Kopfstütze, die automatisch in eine Betriebsposition bringbar ist, mindestens einen Sitzplatzsensor, mittels dessen feststellbar ist, ob der Fondsitzplatz von einem Fahrzeuginsassen besetzt ist, und eine Steuereinheit, der ein Signal des mindestens einen Sitzplatzsensors zuführbar und mittels derer die Kopfstütze ansteuerbar ist. Ferner sieht die Erfindung ein Verfahren zum Betrieb des Kopfstützsystems vor, bei dem die Kopfstütze in die Betriebsposition gebracht wird, wenn von dem mindestens einen Sitzplatzsensor erkannt wird, dass der Fondsitzplatz von einem Fahrzeuginsassen besetzt wird.The Invention provides a headrest system for one Rear seat in a vehicle. The headrest system includes a headrest that automatically in an operating position can be brought, at least one Seat sensor, by means of which it can be determined whether the rear seat occupied by a vehicle occupant, and a control unit, a signal of at least one seat sensor fed and by means of which the headrest is controllable. Furthermore, the invention provides a method for operating the Stanchion Systems in front of which the headrest is brought into the operating position, if of the at least one Seat sensor is detected that the rear seat of a vehicle occupant is occupied.

Die Erfindung hat den Vorteil, dass ein Fahrzeuginsasse auf einem Fondsitzplatz automatisch durch eine Kopfstütze geschützt wird, so dass eine Gefährdung eines Fahrzeuginsassen durch ein Vergessen des Einrichtens einer Kopfstütze ausgeschlossen ist.The Invention has the advantage that a vehicle occupant on a rear seat automatically by a headrest protected will, so a danger of a vehicle occupant by forgetting to set up a headrest is excluded.

Ausführungsbeispiele der Erfindung werden im Folgenden anhand einer Zeichnung näher erläutert.embodiments The invention will be explained in more detail below with reference to a drawing.

Dabei zeigt:there shows:

1 schematisch einen Längsschnitt durch einen Fondsitz mit einem Kopfstützsystem. 1 schematically a longitudinal section through a rear seat with a headrest system.

1 zeigt einen Längsschnitt durch einen Fondsitz 1 eines Fahrzeuges mit einem Kopfstützsystem. Das Kopfstützsystem umfasst eine Kopfstütze 2, die in dem oberen Teil der Rückenlehne des Fondsitzes 1 eingebracht ist und aus der Rückenlehne in eine Betriebsposition ausfahrbar oder ausklappbar ist. 1 shows a longitudinal section through a rear seat 1 a vehicle with a headrest system. The headrest system includes a headrest 2 placed in the upper part of the backrest of the rear seat 1 is introduced and from the backrest in an operating position extendable or foldable.

Der Fondsitz 1 umfasst ferner mindestens einen Sitzplatzsensor 3, mittels dessen feststellbar ist, ob der Fondsitz 1 von einem Fahrzeuginsassen besetzt ist. Ein geeigneter Sitzplatzsensor 3 ist beispielsweise ein in der Sitzfläche des Fondsitzes 1 integrierter Drucksensor.The fund seat 1 further comprises at least one seat sensor 3 by means of which it can be determined whether the rear seat 1 occupied by a vehicle occupant. A suitable seat sensor 3 is for example one in the seat of the rear seat 1 integrated pressure sensor.
