Abstract

In the area of the back rests (3) of the seats, air nozzles (6) are provided for feeding hot air around the head, neck and shoulder areas of the sitting person. One or more air channels (20) leading to the upper edge area of the seat are arranged within or in the rearward area of the back rest, in order to feed the air nozzles with hot air. The heating system is connected to the hot air system of the vehicle. Alternatively, it can be independent of the vehicle system and have a separate heat exchanger (22) and blower (23). Electrical heating wires are provided at least in a part of the air channels. The air nozzles are arranged on a nozzle holder between the back rest (3) and the head support (4).

Description

Die vorliegende Erfindung beschreibt ein Heizsystem für Fahrzeuge, insbesondere solche mit offener oder offen zu fahrender Personenzelle, welchem zum Heizen Warmluft über Kanäle zugeführt wird.The present invention describes a heating system for Vehicles, especially those with open or open Person cell to be moved, which for warm air heating is fed via channels.

Derartige Heizsysteme bei Kraftfahrzeugen sind entweder luftseitig geregelt, d. h. die Heiztemperatur wird über die Luftmenge, die über einen ungeregelten Wärmetau­ scher geführt wird, gesteuert, oder wasserseitig geregelt, d. h. Luft strömt ständig durch den Wärmetau­ scher, wobei dessen Temperatur über die Warmwassermenge reguliert wird. Die Warmluftzufuhr erfolgt allgemein über Lüftungskanäle, die im Bereich der Cockpit- Verkleidung Austrittsöffnungen und Klappen aufweisen. Die Funktion eines derartigen Heizungssystems ist in einem geschlossenen Cockpit durchaus befriedigend, da hier die Strömungsverhältnisse frei von äußeren Einflüssen sind. Anders hingegen verhält es sich bei offenen Fahrzeugen, wie Cabriolets, aber auch offenen Motorboot- oder Leichtflugzeugcockpits. Bei derartigen Cockpits wird der Fahrtwind durch die Windschutzscheibe nach oben abgelenkt und der Luftstrom oberhalb des Fahrzeuges somit stark beschleunigt. Dort reißt die sehr schnell strömende Luft in dem Übergangsbereich zu der vergleichsweise gering bewegten Luft des darunter befindlichen Cockpits eine gewisse Luftmenge mit, wodurch im Fahrzeuginneren ein Unterdruck entsteht. Dieser Unterdruck bewirkt im hinteren Fahrzeugbereich eine teilweise Umkehr der Strömung, die dann im Bereich der Sitze und auch zwischen den Sitzen nach vorne verläuft (Rückströmung) Diese an sich nicht unerwünschte Rückströmung, die einen Teil des Cabrio- Fahrgefühls ausmacht, führt zu einem kühlen Luftzug im Kopf-Nacken-Schulterbereich, was nicht nur bei niedrigen Außentemperaturen zu Unterkühlung und Gesundheitsschäden führen kann.Such heating systems in motor vehicles are either regulated on the air side, d. H. the heating temperature is over the amount of air over an uncontrolled heat build-up shear is guided, controlled, or water-side regulated, d. H. Air constantly flows through the heat rope shear, its temperature over the amount of hot water is regulated. The warm air supply is general via ventilation ducts in the area of the cockpit Cladding has outlet openings and flaps. The function of such a heating system is in a closed cockpit quite satisfactory there here the flow conditions free of external Influences are. However, the situation is different open vehicles, such as convertibles, but also open ones Motor boat or light aircraft cockpits. With such The headwind becomes cockpits through the windshield deflected upwards and the airflow above the Vehicle accelerated strongly. There the tears very fast flowing air in the transition area the comparatively little moving air below cockpits with a certain amount of air, which creates a vacuum inside the vehicle. This negative pressure causes in the rear area of the vehicle a partial reversal of the flow, which is then in the area of the seats and also between the seats to the front runs (backflow) This does not in itself unwanted backflow that is part of the convertible  Driving sensation leads to a cool draft in the Head-neck-shoulder area, which not only in low outside temperatures for hypothermia and Can cause health damage.

In der DE 39 25 809 A1 wird ein Zusatzlüftungssystem für Cabriolets beschrieben, welches durch Zuführung zusätz­ licher Luftmengen in den Cockpit-Bereich der dem unangenehmen empfundenen Luftzug entgegenwirken soll. Hierbei ist in erster Linie an einen Ersatz eines hinter den Rücklehnen der Vordersitze quer verlaufenden Windschutzschirms durch strömungstechnische Maßnahmen gedacht. Eine gezielte Erwärmung des gefährdeten Nacken- und Schulterbereichs findet nicht statt.DE 39 25 809 A1 describes an additional ventilation system for Cabriolets described, which by feeding additional Licher air volumes in the cockpit area of the to counteract unpleasant perceived drafts. This is primarily about replacing one behind the backrests of the front seats Wind shield through fluidic measures thought. A targeted warming of the endangered There is no neck and shoulder area.

Aufgabe der vorliegenden Erfindung ist es daher, ein Heizsystem zu schaffen, das eine Unterkühlung des Kopf-, Nacken- und Schulterbereichs bei der Fahrt mit offenen Fahrzeugen bei Vermeidung lästiger Zugluft wirkungsvoll verhindert, ohne die durchaus erwünschte Cabrio-Brise zu unterbinden.The object of the present invention is therefore a To create a heating system that the hypothermia of the Head, neck and shoulder area when driving with open vehicles while avoiding annoying drafts effectively prevented without the absolutely desired Prevent convertible breeze.

Zwar beschreibt die DE 34 23 657 A1 eine Klimaanlage für einen Fahrzeugsitz bei geschlossenen Fahrzeugen, bei welcher Rückenlehne und Sitzfläche eines Fahrzeugsitzes luftdurchströmt sind; dabei wird aber keine gezielte Warmluftzufuhr im Kopf-, Nacken- und Schulterbereich erreicht. Es handelt sich vielmehr um eine lufttechni­ sche Variante einer bereits bekannten elektrischen Sitzheizung mit im Sitzflächen- und Rückenlehnenbereich angeordneten elektrischen Heizdrähten.DE 34 23 657 A1 describes an air conditioning system for a vehicle seat with closed vehicles, at which backrest and seat of a vehicle seat are air flowed; but this is not a targeted one Warm air supply in the head, neck and shoulder area reached. Rather, it is an air technology cal variant of an already known electrical Seat heating with in the seat and backrest area arranged electrical heating wires.

Die erfindungsgemäße Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. The object of the invention is characterized by the features of claim 1 solved.  

Dabei sind im Bereich der Rückenlehnen Luftdüsen zum Umströmen des Kopf-, Nacken- und Schulterbereichs mit Warmluft vorgesehen. Die hierdurch erzielte räumlich begrenzte Warmluftströmung, welche bis zu den beiden Schulteraußenseiten und zu den Oberarmen reicht, ist für Wohlbefinden der Fahrzeuginsassen wesentlich. Die das Cabrio-Gefühl ausmachende Rückströmung bleibt weiterhin erhalten, ohne daß eine gesundheitsgefähr­ dende Unterkühlung, wie sie insbesondere im Winter oder an kalten Tagen auftritt, stattfindet. Die Steuerung der Warmluft und der Temperatur erfolgt dabei erfin­ dungsgemäß über Luftklappen, Warmwasserregulierungsven­ tile bzw. Gebläsestufen.There are air jets in the area of the backrests Flow around the head, neck and shoulder area with Warm air provided. The spatial achieved thereby limited warm air flow, which up to the two The outside of the shoulder and the upper arms is enough essential for the well-being of vehicle occupants. The the backflow that makes up the convertible feeling remains continue to receive without a health hazard end hypothermia, such as in winter or occurs on cold days. The control the warm air and the temperature are invented according to air flaps, hot water regulation valves tile or blower levels.

Eine vorteilhafte Weiterbildung der vorliegenden Erfindung sieht vor, daß ein oder mehrere zum oberen Randbereich der Sitze führende Luftkanäle innerhalb oder im rückwärtigen Bereich der Rückenlehne angeordnet sind, um die Luftdüsen mit Warmluft zu versorgen. Beispielsweise können die Rahmenrohre der Rückenlehne als Luftkanäle ausgebildet sein, was lediglich einen entsprechenden Anschlußstutzen erforderlich macht. Aber auch zusätzliche Lüftungskanäle, die an der Rückseite der Rückenlehne bzw. an einem gesonderten Träger hinter der Rückenlehne angebracht sind, sind geeignet. Dabei können die gesonderten Luftkanäle beispielsweise aus Kunststoff gefertigt sein.An advantageous development of the present Invention provides that one or more to the top Edge area of the seats leading air ducts inside or arranged in the rear area of the backrest to supply the air nozzles with warm air. For example, the frame tubes of the backrest be designed as air channels, which is only one appropriate connection piece required. But also additional ventilation ducts on the back the backrest or on a separate carrier behind the backrest are attached are suitable. Here can, for example, the separate air ducts Be made of plastic.

Erfindungsgemäß ist ferner vorgesehen, daß das Heizsystem mit dem Warmluftsystem des Fahrzeuges verbunden ist. Dies bietet sich vorzugsweise bei Fahrzeugen mit Mittelmotor an, da sich der Motor bzw. sein Wärmetauscher fast unmittelbar hinter den Sitzleh­ nen, nur durch eine Blechwand davon getrennt, befindet, und somit eine einfache, relativ kurze Warmluftzufüh­ rung möglich ist.According to the invention it is also provided that Heating system with the vehicle's warm air system connected is. This is particularly useful for Vehicles with a mid-engine because the engine or its heat exchanger almost immediately behind the seat back  only separated by a sheet metal wall, and thus a simple, relatively short warm air supply tion is possible.

Das Heizsystem kann auch als gesonderte Heizung mit separatem Wärmetauscher und Gebläse vorgesehen sein. Dies bietet sich insbesondere bei Fahrzeugen mit Front- oder Heckmotor an, da hier die Wege der Luftführung relativ lang sind und die Wärmeverluste bis zu den Sitzen relativ groß sind. Außerdem werden in diesem Fall starke Gebläse notwendig, damit noch eine gute Strömung aus den Luftdüsen vorhanden ist. Prinzipiell ist das System auch auf Luftheizungen anwendbar, wie sie beispielsweise bei luftgekühlten Motoren zur Anwen­ dung kommen. Dabei ist der Wärmetauscher ein Blechge­ bilde, das die heißen Auspuffrohre umgibt und die kalte Luft beim Durchgang erwärmt.The heating system can also be used as a separate heater separate heat exchanger and blower can be provided. This is particularly useful for vehicles with front or rear engine, since here the paths of the air flow are relatively long and the heat losses up to Sitting are relatively large. Also, in this Case strong blowers necessary, so that a good one There is flow from the air jets. In principle the system is also applicable to air heaters, such as they are used, for example, in air-cooled engines come. The heat exchanger is a sheet metal form that surrounds the hot exhaust pipes and the cold ones Air warms as it passes.

Eine zweckmäßige Ausführungsform sieht vor, daß elektrische Heizdrähte, die zusätzlich angebracht sein können, wenigstens in einem Teil der Luftkanäle vorge­ sehen sind. Dies kann, insbesondere bei unzureichender Erwärmung durch den Wärmetauscher zu einer zusätzlichen Erwärmung der Luftströmung der Luftdüsen führen. Des weiteren ergeben sich relativ kurze Aufwärmzeiten, die unabhängig von der Motortemperatur sind.An expedient embodiment provides that electrical heating wires, which are additionally attached can, at least in some of the air channels are seen. This can, especially when there is insufficient Heating by the heat exchanger to an additional Heat the air flow of the air nozzles. Of there are also relatively short warm-up times are independent of the engine temperature.

Des weiteren sieht eine vorteilhafte Ausführungsform vor, daß die Luftdüsen in die Rückenlehne integriert sind. Dies ist insbesondere bei Schalensitzen bei Sportwagen vorteilhaft, da hier die Kopfstütze direkt in die Rückenlehne integriert ist und somit das Ende der Rückenlehne über dem Kopfbereich der im Schalensitz sitzenden Person endet. Die Düsen sind dabei im Kopf- Nackenbereich angeordnet und mit einem oder mehreren Luftkanälen verbunden.It also sees an advantageous embodiment before that the air vents integrated into the backrest are. This is particularly the case with bucket seats Sports car advantageous because the headrest is directly here is integrated into the backrest and thus the end the backrest over the head area in the bucket seat seated person ends. The nozzles are in the head  Neck area arranged and with one or more Air channels connected.

Eine andere vorteilhafte Ausführungsform sieht vor, daß die Luftdüsen an einem Düsenhalter zwischen Rückenlehne und Kopfstütze angeordnet sind. Dies ist bei separaten höhen- und neigungswinkelverstellbaren Kopfstützen vorteilhaft, da der Düsenhalter einfach zwischen dem Haltegestänge der Kopfstütze angeordnet wird. Die Warmluft wird dabei über einen oder mehrere Luftkanäle über einen Stutzen in den Düsenhalter eingeleitet und von dort zu den jeweiligen Düsen geleitet. Dieses System eignet sich auch in hervorragender Weise zur Nachrüstung konventioneller Cabrio-Heizungssysteme.Another advantageous embodiment provides that the air nozzles on a nozzle holder between the backrest and headrest are arranged. This is separate headrests adjustable in height and angle advantageous because the nozzle holder simply between the Holding rod of the headrest is arranged. The Warm air is generated through one or more air channels introduced into the nozzle holder via a nozzle and from there to the respective nozzles. This System is also ideal for Retrofitting conventional convertible heating systems.

Schließlich sieht eine weitere vorteilhafte Ausfüh­ rungsform vor, daß zwischen Luftdüsen und Luftkanälen und/oder zwischen Luftkanälen und dem vorgeschalteten Heizsystem Faltenbälge vorgesehen sind. Dadurch soll die Verstellbarkeit des Sitzes gewährleistet bleiben, ohne die Warmluftzufuhr über das Leitungssystem zu unterbrechen. Der Balg ist dabei vorzugsweise aus Gummi hergestellt.Finally, see another advantageous embodiment tion form that between air nozzles and air channels and / or between air channels and the upstream Heating system bellows are provided. This is supposed to the adjustability of the seat remains guaranteed, without the warm air supply via the pipe system interrupt. The bellows is preferably made of rubber produced.
