Abstract
Description
Die Erfindung betrifft eine Sitzanlage, insbesondere einen Fahrzeugsitz, für einen Kraftwagen gemäß dem Oberbegriff von Patenanspruch 1.The invention relates to a seat system, in particular a vehicle seat, for a motor vehicle according to the preamble of patent claim 1.
Aus dem allgemeinen Stand der Technik sind Sitzanlagen, insbesondere Fahrzeugsitze, für Kraftwagen bekannt, welche jeweils wenigstens ein Sitzanlagenelement umfassen. Das Sitzanlagenelement weißt zumindest ein Polsterteil und einen Bezug auf, mit welchem das Polsterteil bezogen ist. Bei dem Sitzanlagenelement handelt es sich beispielsweise um ein Sitzelement der Sitzanlagen, auf welchem ein Sitzinsasse der Sitzanlage sitzen kann. Bei dem Sitzanlagenelement kann es sich auch um eine Rückenlehne der Sitzanlage handeln, an die sich der Sitzinsasse anlehnen kann.Seat systems, in particular vehicle seats, for motor vehicles are known from the general state of the art, which each comprise at least one seat system element. The seat element element has at least one padded part and a cover with which the padding part is covered. The seat system element is, for example, a seat element of the seat systems on which a seat occupant of the seat system can sit. The seat element may also be a backrest of the seat, to which the seat occupant can lean.
Ferner ist es aus dem allgemeinen Stand der Technik bekannt, Innenräume von Kraftwagen derart zu beheizen, das beispielsweise mittels eines Wärmetauschers erwärmte Luft aus Düsen im Innenraum ausströmt. Diese Düsen sind herkömmlicher Weise relativ weit von der im Innenraum angeordneten Sitzanlage entfernt, so dass sich ein Wärmeempfinden der Sitzinsassen infolge der Beaufschlagung der Sitzinsassen mit der erwärmten und aus den Düsen ausströmenden Luft verzögert einstellt und insbesondere bei kalter Witterung sehr spät auftritt.Furthermore, it is known from the general state of the art to heat interiors of motor vehicles in such a way that, for example by means of a heat exchanger, heated air flows out of nozzles in the interior. These nozzles are conventionally relatively far away from the seat system arranged in the interior, so that a heat sensation of the seat occupants due to the application of the seat occupant with the heated air flowing out of the nozzles and retarded setting occurs very late, especially in cold weather.
Die erwärmte Luft wird dabei über Strömungskanäle zu den Düsen geleitet, wobei aufgrund von Wärmeübergängen ein Wärme- und damit Energieverlust auftritt, bis die erwärmte Luft die Düsen und insbesondere die Sitzinsassen erreicht.The heated air is passed through flow channels to the nozzles, due to heat transfer heat and thus energy loss occurs until the heated air reaches the nozzles and in particular the seat occupants.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Sitzanlage, insbesondere einen Fahrzeugsitz, für einen Kraftwagen bereit zu stellen, welcher eine verbesserte und insbesondere effiziente Temperierung des Sitzinsassen ermöglicht.It is therefore an object of the present invention to provide a seat system, in particular a vehicle seat, for a motor vehicle, which allows an improved and in particular efficient temperature control of the seat occupant.
Diese Aufgabe wird durch eine Sitzanlage, insbesondere einen Fahrzeugsitz, mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben.This object is achieved by a seat system, in particular a vehicle seat, having the features of patent claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the remaining claims.
Zur Realisierung einer besonders energieeffizienten und schnellen Erwärmung des Sitzinsassen ist erfindungsgemäß vorgesehen, dass unter dem Sitzbezug wenigstens ein Heizelement am Sitzbezug angeordnet ist. Dem Heizelement ist dabei wenigstens eine Ausströmöffnung des Bezugs zugeordnet, die von mittels des Heizelements erwärmter Luft durchströmbar ist. Durch die Anordnung des Heizelements am Bezug ist nicht nur die aus der Ausströmöffnung ausströmende Luft sondern auch der Bezug direkt beheizbar, beziehungsweise erwärmbar. Dadurch wird Wärme mittels des Heizelements direkt oder zumindest körpernah am Sitzinsassen bereitgestellt. Infolge dieser Bereitstellung der Wärme können die eingangs geschilderten Wärmeverluste gering gehalten werden.To realize a particularly energy-efficient and rapid heating of the seat occupant, the invention provides that under the seat cover at least one heating element is arranged on the seat cover. The heating element is associated with at least one outflow opening of the reference, which can be flowed through by the heated air by means of the heating element. Due to the arrangement of the heating element on the reference not only the air flowing out of the outflow opening air but also the cover is directly heated, or heated. As a result, heat is provided by means of the heating element directly or at least close to the body on the seat occupant. As a result of this provision of heat, the initially described heat losses can be kept low.
Das Heizelement weist vorzugsweise eine im Wesentlichen flächige Erstreckung auf und ist somit als Flächenheizelement ausgebildet. Dabei ist das Heizelement vorteilhaferweise im Wesentlichen flächig an dem Bezug angeordnet, insbesondere flächig an dem Bezug kontaktiert, wodurch ein besonders effizienter Wärmeübergang vom Heizelement an den Bezug und weiter an den Sitzinsassen realisiert ist.The heating element preferably has a substantially planar extension and is thus designed as a surface heating element. In this case, the heating element is advantageously arranged substantially flat on the cover, in particular flat contact with the cover, whereby a particularly efficient heat transfer from the heating element to the cover and further to the seat occupant is realized.
Ferner ist ein besonders schnelles Wärmeempfinden des Sitzinsassen realisiert, da dieser die bereitgestellt Wärme auch bei kalter Witterung besonders schnell verspürt. Die Integration des Heizelements bei der erfindungsgemäßen Sitzanlage birgt ferner den Vorteil, dass auch das Heizelement durch den Bezug abgedeckt und somit optisch nicht wahrnehmbar ist. Dies kommt dem optischen Eindruck der erfindungsgemäßen Sitzanlage zugute. Des Weiteren hält die Anordnung des Heizelements unter dem Sitzbezug an diesem den Bauraumbedarf der Sitzanlage gering. Insbesondere kann der Bauraumbedarf der Sitzanlage im Bereich einer Rückseite eines Rückenlehnenelements der Sitzanlage gering gehalten werden.Furthermore, a particularly quick feeling of heat of the seat occupant is realized, as this feels the provided heat particularly quickly in cold weather. The integration of the heating element in the seat system according to the invention also has the advantage that the heating element is covered by the cover and thus optically imperceptible. This benefits the visual impression of the seating system according to the invention. Furthermore, the arrangement of the heating element under the seat cover at this keeps the space requirement of the seat system low. In particular, the space requirement of the seat system in the region of a rear side of a backrest element of the seat system can be kept low.
Die erfindungsgemäße Sitzanlage birgt ferner den Vorteil, dass der Sitzinsasse besonders nahe an dem Heizelement sitzt und dieses gegebenenfalls zumindest teilweise überdeckt. So kann der Sitzinsasse Körperwärme an das Heizelement abgeben und dieses erwärmen, so dass das Heizelement energiearm und effizient betrieben werden kann. Dies ist insbesondere von Vorteil, wenn das Heizelement beispielsweise bei einer längeren Standzeit des insbesondere als Personenkraftwagen ausgebildeten Kraftwagens eine längere Zeit deaktiviert war und sich bei einer daran anschließenden Aktivierung während einer Startphase zunächst erwärmen muss.The seat system according to the invention also has the advantage that the seat occupant sits particularly close to the heating element and this optionally at least partially covered. Thus, the seat occupant can emit body heat to the heating element and heat it, so that the heating element can be operated low energy and efficient. This is particularly advantageous if the heating element has been deactivated for a longer time, for example, during a longer service life of the motor vehicle designed in particular as a passenger car, and must first be heated during a subsequent activation during a starting phase.
Der Sitzinsasse fungiert somit bei der erfindungsgemäßen Sitzanlage insbesondere in der Startphase des Heizelements nicht nur als Wärmeempfänger sondern auch als Wärmespender für das Heizelement. Das körpernah angeordnete Heizelement ermöglicht bei der erfindungsgemäßen Sitzanlage ferner die Darstellung einer so genannten Klimazelle, von welcher der Sitzinsasse körpernah zumindest bereichsweise eingehüllt und dadurch besonders energieeffizient temperiert, insbesondere beheizt, werden kann.The seat occupant thus acts in the seat arrangement according to the invention, in particular in the starting phase of the heating element not only as a heat receiver but also as a heat donor for the heating element. The close to the body arranged heating element also allows in the seat according to the invention the representation of a so-called climate cell, of which the seat occupant close to the body wrapped at least partially and thus tempered particularly energy efficient, in particular heated, can be.
