Description

Vorrichtung und Verfahren zum Einstellen eines Luftstroms einer Luftversorgungseinrichtung für einen Fahrzeugsitz Apparatus and method for adjusting an air flow of an air supply device for a vehicle seat
Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zum Einstellen eines Luftstroms einer Luftversorgungseinrichtung für einen Fahrzeugsitz insbesondere eines Cabriolets.The present invention relates to an apparatus and a method for adjusting an air flow of an air supply device for a vehicle seat, in particular a convertible.
Aus dem Stand der Technik sind unterschiedliche Luftversorgungseinrichtungen bekannt, welche in einem Fahrzeugsitz eines Cabriolets integrierbar sind und mit Hilfe von welchen ein definierter Luftstrom den Fahrzeuginsassen bereitgestellt werden kann.Different air supply devices are known from the prior art, which can be integrated in a vehicle seat of a convertible and with the aid of which a defined air flow can be made available to the vehicle occupants.
Aus dem deutschen Gebrauchsmuster DE 92 01 474 Ul ist beispielsweise eine Luftversorgungseinrichtung bekannt, bei welcher im oberen Bereich des Fahrzeugsitzes wenigstens eine Luftausströmöffnung vorgesehen ist, über welche der Kopf-, Schulter- und Nackenbereich des Sitzinsassen mit einem definierten Luftstrom beaufschlagbar ist. Ein solcher Luftstrom soll die beim Fahren mit einem offenen Verdeck unerwünschten, vor allem rückseitig in den offenen Fahrgastinnenraum einströmenden Zuglufterscheinungen vermindern. Hierzu wird die Luftversorgungseinrichtung mit Luft beschickt, die beim Fahren über vorgesehene Einströmquerschnitte aufgefangen und durch Leitungen und Kanäle mittels Erzeugung eines Staudrucks oder unter Zuhilfenahme eines Gebläses zur Luftausströmöffnung gefördert wird. Darüber hinaus ist aus der deutschen Offenlegungsschrift DE 102 26 008 Al eine Luftversorgungseinrichtung für einen Sitz eines Cabriolets erkannt, bei welcher ein verbesserter Komfort für die Sitzinsassen beim offenen Fahren bereitgestellt wird, indem der aus einer Luftaustrittsöffnung ausströmende Luftstrom mittels einer Steuereinrichtung in Abhängigkeit von automatisch oder individuell einstellbaren Parameterwerten so einstellbar ist, dass die Sitzinsassen den ausströmenden Luftstrom als angenehm empfinden. Hierzu ist innerhalb der Luftversorgungseinrichtung ein Heizelement vorgesehen, welches die aus der Umgebung angesaugte Luft auf eine bestimmte Temperatur vorheizen kann. Darüber hinaus wird mittels der Steuereinrichtung der Durchsatz der ausströmenden Luft, d. h. die Stärke des Luftstroms, über ein Gebläse eingestellt.From the German Utility Model DE 92 01 474 Ul, for example, an air supply device is known in which at least one Luftausströmöffnung is provided in the upper region of the vehicle seat, via which the head, shoulder and neck area of the seat occupant can be acted upon with a defined air flow. Such a flow of air is intended to reduce the undesirable when driving with an open top, especially on the back flowing into the open passenger compartment draft phenomena. For this purpose, the air supply device is charged with air, which is collected while driving over intended inflow and conveyed by lines and channels by generating a dynamic pressure or with the aid of a blower to the air outlet. In addition, DE 102 26 008 A1 discloses an air supply device for a seat of a convertible in which an improved comfort for the seat occupants during open driving is provided by the air flow flowing out of an air outlet opening by means of a control device depending on automatically or individually adjustable parameter values can be set so that the seat occupants perceive the outflowing air flow as pleasant. For this purpose, a heating element is provided within the air supply device, which can preheat the air sucked from the environment to a certain temperature. In addition, the flow rate of the outflowing air, ie the strength of the air flow, is adjusted by means of the control device via a blower.
Bei starker Sonneneinstrahlung lässt sich eine starke Aufheizung des Nacken- und Schulterbereichs des Sitzinsassen nicht vermeiden. Die aufgrund der aerodynamisch stark verbesserten Fahrzeugkonturen sich nur noch geringfügig einstellende, in den Fahrgastinnenraum rückseitig einströmende Luftströmung ist in vielen Fällen nicht mehr in der Lage, den Nacken- bzw. Schulterbereich in ausreichendem Maße zu kühlen.In strong sunlight, a strong heating of the neck and shoulder area of the seat occupant can not be avoided. The due to the aerodynamically greatly improved vehicle contours only slightly adjusting, in the passenger compartment back inflowing air flow is in many cases no longer able to cool the neck or shoulder area to a sufficient extent.
Die aus dem Stand der Technik bekannten Vorrichtungen und Verfahren dienen lediglich dazu, die künstlich erzeugte Luftströmung auf eine bestimmte Temperatur vorzuheizen.The devices and methods known from the prior art serve only to preheat the artificially generated air flow to a certain temperature.
Ausgehend davon ist es die Aufgabe der vorliegenden Erfindung, eine Vorrichtung und ein Verfahren bereitzustellen, mit Hilfe von welchen auf einfache Art und Weise ein Abkühlen des Nacken- bzw. Schulterbereichs eines Sitzinsassen bewerkstelligt werden kann. Gelöst wird diese Aufgabe durch eine Luftversorgungseinrichtung mit den Merkmalen des Patentanspruchs 1 sowie mit einem Verfahren mit den Merkmalen des Patentanspruchs 6.Based on this, it is the object of the present invention to provide an apparatus and a method by means of which in a simple manner, a cooling of the neck or shoulder region of a seat occupant can be accomplished. This object is achieved by an air supply device having the features of patent claim 1 and by a method having the features of patent claim 6.
Der Kern der Erfindung liegt demzufolge darin, dass bei einer Außentemperatur, welche größer als eine vorbestimmte Grenztemperatur ist, und/oder bei einer über eine bestimmte Dauer bzw. Intensität hinausgehende Sonneneinstrahlung in den Fahrgastinnenraum ein innerhalb einer das Verfahren umsetzenden Luftversorgungseinrichtung, welche insbesondere in einem Fahrzeugsitz eines Cabriolets integriert ist, vorgesehenes Heizelement deaktiviert wird, so dass der Luftstrom nur mit der jeweils vorherrschenden Außentemperatur ausströmen kann.The core of the invention is therefore that at an outdoor temperature which is greater than a predetermined limit temperature, and / or at a more than a certain duration or intensity of solar radiation into the passenger compartment within a process implementing air supply device, which in particular in a Vehicle seat of a convertible is integrated, provided heating element is disabled, so that the air flow can flow only with the prevailing outside temperature.
Dieser künstlich erzeugte Luftstrom soll die auftretende Luftrückströmung in den Fahrgastinnenraum unterstützen, so dass zusätzlich in einem bestimmten Maße der Nacken- und Schulterbereich des Sitzinsassen durch ein zusätzlich gesteuertes Anblasen mit Luft komfortabel abgekühlt werden kann.This artificially generated airflow is to support the air backflow occurring in the passenger compartment, so that in addition to a certain extent the neck and shoulder region of the seat occupant can be comfortably cooled by an additional controlled blowing air.
Die Steuerung des Heizelements erfolgt durch eine Steuereinrichtung, welche über Sensoren die Außentemperatur und/oder eine Sonneneinstrahlung zu detektieren vermag.The control of the heating element is effected by a control device, which is able to detect the outside temperature and / or solar radiation via sensors.
Die von der Steuereinrichtung zu berücksichtigende Grenztemperatur bestimmt sich beispielsweise in Abhängigkeit der jeweils vorherrschenden Fahrzeuggeschwindigkeit und/oder der Intensität der Sonneneinstrahlung.The limit temperature to be taken into account by the control device is determined, for example, as a function of the respective prevailing vehicle speed and / or the intensity of the solar radiation.
Darüber hinaus ist es vorgesehen, dass die Grenztemperatur manuell bzw. individuell von dem Sitzinsassen eingestellt werden kann.In addition, it is provided that the limit temperature can be adjusted manually or individually by the seat occupant.
Vorzugsweise liegt die systemseitig festgelegte Grenztemperatur bei 25° C. Das Verfahren gemäß der Erfindung ist dadurch gekennzeichnet, dass bei einer Außentemperatur, welche größer als eine vorbestimmte Grenztemperatur ist, und/oder bei fortwährender Sonneneinstrahlung das Heizelement (6) deaktiviert wird, so dass der Luftstrom mit der jeweils vorherrschenden Außentemperatur ausströmt.Preferably, the system-defined limit temperature is 25 ° C. The method according to the invention is characterized in that at an outside temperature which is greater than a predetermined limit temperature, and / or continuous solar radiation, the heating element (6) is deactivated, so that the air flow flows out with the prevailing outside temperature.
Darüber hinaus zeichnet sich das Verfahren in einer weiteren Ausführung dadurch aus, dass sich die Stärke des Luftstroms zusätzlich in Abhängigkeit der jeweils vorherrschenden Fahrzeuggeschwindigkeit, individuell oder automatisch, einstellen lässt.In addition, the method is characterized in another embodiment by the fact that the strength of the air flow can additionally be adjusted depending on the prevailing vehicle speed, individually or automatically.
Die erfindungsgemäße Vorrichtung soll nun anhand des in den beiliegenden Zeichnungen dargestellten Ausführungsbeispiels näher erläutert werden.The device according to the invention will now be explained in more detail with reference to the embodiment shown in the accompanying drawings.

Diese Luftaustrittsöffnung 3 steht mit einem in der Rückenlehne 2 des Fahrzeugsitzes integrierten Luftkanal 4 in Verbindung, welcher die Luftaustrittsöffnung 3 mit einem Gebläse 5 verbindet, welches Utngebungsluft, in der Regel im rückseitigen Bereich der Rückenlehne 2, ansaugt.In the region of the headrest 1 of the vehicle seat, an air outlet opening 3 of the air supply device is integrated. This air outlet opening 3 communicates with an air duct 4 integrated in the backrest 2 of the vehicle seat, which connects the air outlet opening 3 with a blower 5, which sucks in ambient air, generally in the rear region of the backrest 2.
Innerhalb des Luftkanals 4 ist ein Heizelement 6 integriert, mit Hilfe von welchem die von dem Gebläse 5 angesaugte Umgebungsluft auf eine vorbestimmte Temperatur vorgeheizt werden kann, bevor diese aus der Luftaustrittsöffnung 3 in der Kopfstütze 1 austritt.Within the air channel 4, a heating element 6 is integrated, by means of which the sucked by the blower 5 ambient air can be preheated to a predetermined temperature before it exits the air outlet opening 3 in the headrest 1.
In Figur 2 ist dieser Fahrzeugsitz in einer Seitenansicht gezeigt.In Figure 2, this vehicle seat is shown in a side view.
Wie zu erkennen ist, steht das Heizelement 6 mit einer Steuereinrichtung 7 in Verbindung.As can be seen, the heating element 6 is connected to a control device 7 in connection.
Diese Steuereinrichtung 7 steuert die Aktivität, d. h. den Einschalt- bzw. Ausschaltprozess des Heizelements 6, in Abhängigkeit der durch einen Temperatursensor 8 gemessenen Außentemperatur und einer in einem Speicher der Steuereinrichtung 7 abgelegten vorbestimmten Grenztemperatur.This controller 7 controls the activity, i. H. the turn-on or turn-off of the heating element 6, as a function of the measured by a temperature sensor 8 outside temperature and a stored in a memory of the control device 7 predetermined limit temperature.
Die Steuereinrichtung 7 lässt sich allerdings auch bordseitig über einen Schalter 9 von dem Sitzinsassen ansteuern, wobei er entweder die Temperatur des anzusaugenden Luftstromes über das Heizelement 6 steuert oder dieses Heizelement 6 bei Bedarf abschalten kann. However, the control device 7 can also be controlled on board by a switch 9 of the seat occupant, where he controls either the temperature of the air flow to be sucked on the heating element 6 or 6 can switch off this heating element if necessary.
