Am oberen Ende ist der aufrecht verlaufende Kanal 20 nach vorne hin L-förmig abgewinkelt und endet an einer im Weiteren noch detaillierter erläuterten Luftdüse 24 an der Vorderseite 26 der Kopfstütze 14. Über die Luftdüse 24 tritt der durch die Luftversorgungseinrichtung 16 erzeugte , vorzugsweise warme Luftstrom in Richtung des Kopf- , Schulter- und Nackenbereichs des Sitzinsassen aus . Hierdurch kann beispielsweise bei einer Fahrt mit einem offenen Kraftwagen die naturgemäß entstehende , den Sitzinsassen störende Rückströmung oder Verwirbelung der diesen umgebenden Luft kompensiert werden . Um den aus der Luftdüse 24 austretenden warmen Luftstrom -je nach Größe und Sitzposition des Sitzinsassen- ausrichten zu können, umfasst die Luftdüse 24 im Weiteren noch näher erläuterte Leitelemente 32.In the figures Ia and Ib, the backrest 10 of a motor vehicle seat is shown in a schematic perspective front view or in a schematic side view. Of the backrest 10 is in Figure Ia in Essentially a rear paneling 12, a headrest 14 and a backrest cushion 15 recognizable. The motor vehicle seat is designed here as integral seat, wherein the headrest 14 is arranged in overlap with the backrest 10 in front of this. The headrest 14 is height adjustable relative to the backrest 10 via guide means, not shown. Within the backrest 10, an air supply device 16 is arranged, which comprises as essential component a schematically indicated fan 18 at the lower end of the air supply device 16 and an air duct 20 arranged above the blower 18. Within the air duct 20, a heating element 22 indicated by dashed lines in FIG. 1a is provided at a distance above and on the pressure side of the blower 18, by means of which the air flow generated by the blower 18 can be heated. At the upper end of the upright channel 20 is angled towards the front L-shaped and ends at a later explained in more detail air nozzle 24 on the front 26 of the headrest 14. About the air nozzle 24, the generated by the air supply device 16, preferably warm air flow towards the head, shoulder and neck area of the seat occupant. As a result, for example, when traveling with an open motor vehicle, the naturally occurring, the seat occupant disturbing backflow or turbulence of the surrounding air can be compensated. In order to be able to align the warm airflow emerging from the air nozzle 24, depending on the size and seating position of the seat occupant, the air nozzle 24 furthermore comprises guide elements 32 which are explained in more detail below.
In Figur Ib ist darüber hinaus in Seitenansicht der Verlauf des Lehnenpolsters 15 im zentralen Spiegelbereich 30 der Rückenlehne 10 gestrichelt angedeutet . Hierdurch wird auch erkennbar, dass die Luftversorgungseinrichtung 16 beziehungsweise deren Luftkanal 20 und deren Gebläse 18 vollständig innerhalb der Rückenlehne 10 angeordnet und lediglich die Luftdüse 24 von außen sichtbar ist .In FIG. 1 b, the profile of the backrest cushion 15 in the central mirror area 30 of the backrest 10 is also indicated by dashed lines in a side view. As a result, it can also be seen that the air supply device 16 or the air duct 20 and the blower 18 are arranged completely within the backrest 10 and only the air nozzle 24 is visible from the outside.
In Figur 2 ist in ausschnittsweiser schematischer Perspektivansicht die Kopfstütze 14 der Rückenlehne 10 gemäß den Figuren Ia und Ib dargestellt . An der dem Sitzinsassen zugewandten Vorderseite 26 mündet die Luftdüse 24 der Luftversorgungseinrichtung 16 in einem unteren Bereich der Kopfstütze 14. Die Vorderseite 26 der Kopfstütze 14 ist dabei mit einem Polster versehen und mit einem Polsterbezug 28 verkleidet .In FIG. 2, the headrest 14 of the backrest 10 according to FIGS. 1a and 1b is shown in a fragmentary schematic perspective view. At the front of the seat facing the front 26 opens the air nozzle 24 of the air supply device 16 in a lower region of the headrest 14. The front 26 of the headrest 14 is provided with a cushion and covered with a cushion cover 28.
In Zusammenschau mit Figur 3 , in welcher eine schematische Schnittansicht durch die Kopfstütze 14 entlang der Linie III- III in Figur 2 gezeigt ist , wird die zurückspringende Anordnung der Luftdüse 24 gegenüber der Vorderseite 26 der Kopfstütze 14 erkennbar . Die Luftdüse 24 ist dabei um ein so genanntes Komfortmaß K gegenüber der Vorderseite 26 der Kopfstütze 14 nach hinten versetzt angeordnet , welches vorzugsweise zwischen 5 mm und 30 mm beträgt . Der Luftkanal 20 endet dabei im Bereich einer umlaufenden Düsenumrandung 34 , welche hier als in Fahrzeugquerrichtung lang gestreckte ovale Öffnung ausgebildet ist . Gleichfalls wäre natürlich auch eine andere geometrische Gestaltung der umlaufenden Düsenumrandung 34 denkbar . Im gezeigten Ausführungsbeispiel ist die umlaufenden Düsenumrandung 34 mit ihrer dem Sitzinsassen zugewandten Stirnseite 36 um das besagte Komfortmaß K zurückspringend gegenüber der Vorderseite 26 der Kopfstütze angeordnet . Innerhalb der Düsenumrandung 34 beziehungsweise dem Luftkanal 20 sind eine Mehrzahl von vertikal verlaufenden Leitelementen 32 um eine j eweilige Schwenkachse SV schwenk gelagert , mit welchen der über die Luftdüse 24 aus der Luftversorgungseinrichtung 16 austretende Luftström indi- viduell ausgerichtet werden kann. Im vorliegenden Ausführungsbeispiel sind fünf vertikale Leitelemente 32 vorgesehen, welche beispielsweise über einen Verbindungsstab 40 oder eine ähnliche Einrichtung miteinander schwenk gekoppelt sind. In Figur 3 ist das repräsentativ dargestellte Leitelement 32 in einer senkrechten Schwenklage zu der durch die umlaufenden Düsenumrandung 34 aufgespannten Ebene E dargestellt , also in einer Lage, in welcher der aus der Luftversorgungseinrichtung 16 austretende Luftstrom die Leitelemente 32 geradewegs und ohne Ablenkung durchströmt . In der dargestellten, zur Ebene E senkrechten Schwenklage des Leitelements 32 ist dessen vorderstes Ende 40 natürlich am kürzesten von der Vorderseite 26 der Kopfstütze 14 entfernt . Demgemäß wäre der Abstand zwischen dem vorderen Ende 40 und der Vorderseite 26 der Kopfstütze 14 bei einer schrägen Schwenkeinstellung des Leitelementes 32 größer . Doch auch bei dem hier dargestellten kürzestmöglichen Abstand zwischen dem vorderen Ende 40 des Leitelementes 32 ist dieses so bemessen und angeordnet , dass es -als Teil der Luftdüse 24- gegenüber der Vorderseite 26 der Kopfstütze 14 mindestens um das besagte Komfortmaß K zurückspringend angeordnet ist . Im vorliegenden Ausführungsbeispiel kommt das vordere Ende 40 j edes Leitelementes 32 zudem unabhängig von seiner Schwenkstellung allenfalls auf Höhe oder aber hinter der durch die umlaufende Düsenumrandung 34 der Luftdüse 24 ausgespannten Ebene E zu liegen. Mit anderen Worten ist also jedes Bauteil der Luftdüse 24 -also sowohl die umlaufende Düsenumrandung 34 , wie auch j edes der Leitelemente 32 - um das Komfortmaß K gegenüber der Vorderseite 26 der Kopfstütze 14 nach hinten versetzt angeordnet .In conjunction with Figure 3, in which a schematic sectional view through the headrest 14 along the line III-III in Figure 2 is shown, the recessed arrangement of the air nozzle 24 relative to the front 26 of the headrest 14 can be seen. The air nozzle 24 is arranged offset by a so-called comfort measure K with respect to the front side 26 of the headrest 14 to the rear, which is preferably between 5 mm and 30 mm. The air duct 20 ends in the region of a circumferential nozzle border 34, which is designed here as an oval opening elongated in the vehicle transverse direction. Likewise, of course, another geometric design of the circumferential nozzle border 34 would be conceivable. In the illustrated embodiment, the circumferential nozzle edge 34 is arranged with its the seat occupant facing end face 36 to the said comfort measure K jumping back from the front side 26 of the headrest. Within the nozzle border 34 or the air channel 20, a plurality of vertically extending guide elements 32 are pivotally mounted about a respective pivot axis SV, with which the air flow exiting via the air nozzle 24 from the air supply device 16 is indicated. can be aligned. In the present embodiment, five vertical guide elements 32 are provided, which are coupled to each other, for example, via a connecting rod 40 or a similar device. In Figure 3, the guide member 32 representatively shown in a vertical pivot position to the plane defined by the peripheral nozzle edge 34 plane E, ie in a position in which the exiting the air supply device 16 air flow flows through the guide elements 32 straight and without deflection. In the illustrated, perpendicular to the plane E pivot position of the guide element 32 whose foremost end 40 is of course the shortest distance from the front 26 of the headrest 14. Accordingly, the distance between the front end 40 and the front 26 of the headrest 14 at an oblique pivot adjustment of the guide element 32 would be greater. However, even at the shortest possible distance between the front end 40 of the guide element 32 shown here, this is dimensioned and arranged so that it-as part of the air nozzle 24 -is arranged to spring back relative to the front side 26 of the headrest 14 at least by the said comfort measure K. In the present exemplary embodiment, the front end 40 of each guide element 32 also comes to lie, at best, either level or behind the plane E stretched out by the peripheral nozzle border 34 of the air nozzle 24, independently of its pivotal position. In other words, therefore, each component of the air nozzle 24 -also both the circumferential nozzle border 34, and j edes of the guide elements 32 - arranged offset by the comfort measure K relative to the front 26 of the headrest 14 to the rear.
Im Mündungsbereich vorderseitig der Düsenumrandung 34 erweitert sich die Luftausströmöffnung in ihrem Querschnitt . Die entsprechende Gestaltung der Bepolsterung der Vorderseite 26 der Kopfstütze 14 beziehungsweise der Polsterbezug 28 ist durch entsprechende Linien 42 deutlich gemacht .In the mouth region on the front side of the nozzle border 34, the air outlet opening widens in its cross section. The corresponding design of the upholstery of the front 26th the headrest 14 or the upholstery cover 28 is made clear by corresponding lines 42.
In einer weiteren Ausgestaltungsform der Erfindung ist neben den in Fahrzeughochrichtung beziehungsweise vertikal verlaufenden Leitelementen 32 mindestens ein weiteres Leitelement 44 vorgesehen, welches zumindest annähernd horizontal beziehungsweise in Fahrzeugquerrichtung sich erstreckt . Das horizontale Leitelement 44 ist dabei um eine Schwenkachse SH innerhalb der umlaufenden Düsenumrandung 34 schwenkbar angelagert . Mittels dieses wenigstens einen Leitelementes 44 ist der aus der Luftversorgungseinrichtung austretende Luftstrom individuell höheneinstellbar . Auch das Leitelement 44 ist entsprechend ausgebildet und innerhalb der Düsenumrandung 34 angelagert , so dass dessen vorderen Ende 46 unabhängig von der eingestellten Schwenkposition j eweils zumindest um das Komfortmaß K gegenüber der Vorderseite 26 der Kopfstütze 14 nach hinten versetzt zu liegen kommt . Vorzugsweise kommt das vordere Ende 46 des horizontalen Leitelementes 44 -wie in Figur 3 dargestellt- auf Höhe oder hinter der durch die umlaufende Düsenumrandung 34 aufgespannten Ebene E zu liegen. In a further embodiment of the invention, at least one further guide element 44 is provided in addition to the in vehicle vertical direction or vertically extending guide elements 32 which extends at least approximately horizontally or in the vehicle transverse direction. The horizontal guide element 44 is attached pivotably about a pivot axis SH within the peripheral nozzle border 34. By means of this at least one guide element 44, the air flow emerging from the air supply device is individually height adjustable. Also, the guide element 44 is formed accordingly and attached within the nozzle border 34, so that its front end 46, regardless of the set pivot position is in each case at least offset by the Komfortmaß K relative to the front 26 of the headrest 14 to the rear. As is shown in FIG. 3, the front end 46 of the horizontal guide element 44 preferably lies at the level or behind the plane E spanned by the peripheral nozzle border 34.
