Abstract

The motor vehicle seat has air blowing nozzles installed on the edge sections of the surface of the seat section (1) facing the seat's occupant and parallel and adjacent to the side edges. These and forward orientated air blowing nozzles installed on the front side of the headrest (3) are orientated in such a way that an air flow emanating from them forms an air jacket around the seat's occupant. Air blowing nozzles are also provided in the armrests to support the formation of the air jacket.

Description

Die Erfindung betrifft einen Kraftfahrzeugsitz nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a motor vehicle seat the preamble of claim 1.

Ein Kraftfahrzeugsitz der als bekannt vorausgesetzten Art ( DE 100 54 008 A1 ) weist einen luftdurchlässigen Sitzbereich auf, auf dessen von der Kontaktfläche mit dem Sitzbenutzers abgewandten Seite ein Luftstrom auftrifft, der den Sitzbereich durchströmt. Ein weiterer Luftstrom wird zur Kopfstütze geführt und durch Luftausblasdüsen auf Kopf und Nackenbereich des Sitzbenutzers gerichtet. Dieser Luftstrom soll insbesondere dem Fahrtwind bei geöffnetem Fahrzeugverdeck entgegenwirken.A motor vehicle seat of the type assumed to be known ( DE 100 54 008 A1 ) has an air-permeable seat area, on the side of which faces away from the contact surface with the seat user, an air flow strikes the seat area. Another air stream is led to the headrest and directed through air outlet nozzles at the head and neck area of the seat user. This air flow is intended in particular to counteract the headwind when the vehicle roof is open.

Es ist außerdem bekannt, im Armaturenbrett eines Kraftfahrzeugs richtbare Ausblasöffnungen einer Klimaanlage vorzusehen, mit denen punktuelle Anblasstellen des Kraftfahrzeuginnenraums oder des Sitzbenutzers erreicht werden. Insbesondere bei durch Sonneneinstrahlung aufgeheizten Innenräumen und Sitzoberflächen vergeht bei dieser Kühlung eine vergleichsweise lange Zeitdauer, bis sich eine für den Be nutzer erträgliche Innenraumtemperatur und Sitzflächentemperatur einstellt.It is also known to have a dashboard Directional exhaust ports to provide an air conditioning system with which selective blowing points of the motor vehicle interior or the seat user can be reached. Especially in the case of interior rooms heated by solar radiation and seating surfaces one passes with this cooling comparatively long period of time until a user-friendly indoor temperature and Seat temperature established.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen klimatisierten Kraftfahrzeugsitz der als bekannt vorausgesetzten Art so auszubilden, daß schnell ein für dessen Benutzer angenehmes Klima geschaffen werden kann.Based on this state of the art the invention has for its object an air-conditioned motor vehicle seat of the type assumed to be known in such a way that quickly one for whose user can create a pleasant climate.

Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Patentanspruchs 1.This task is solved with the features of claim 1.

Durch die Luftströme und die belüfteten Kontaktflächen zwischen Sitzbereichen und Sitzbenutzer wird sehr schnell eine den Sitzbenutzer umgebende, angenehm temperierte Lufthülle, vergleichbar einem Kokon, geschaffen, die weitgehend unabhängig von der Temperatur des übrigen Fahrgastraums sein kann. Der Luftaustausch des gesamten Fahrgastraums und die Kühlung der aufgeheizten Innenraumflächen, die mit dem Sitzbenutzer nicht unmittelbar in Kontakt treten, kann allmählich erfolgen, ohne das Wohlbefinden des Sitzbenutzers auch nur vorübergehend zu beeinträchtigen.Due to the air currents and the ventilated contact surfaces between Seating areas and seat users will very quickly become the seat user surrounding, pleasantly tempered air envelope, comparable to a cocoon, created that are largely independent on the temperature of the rest Passenger compartment can be. The air exchange of the entire passenger compartment and cooling the heated interior surfaces, that cannot come into direct contact with the seat user gradually take place without the well-being of the seat user even temporarily to affect.

Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Preferred embodiments of the invention result itself from the subclaims.

Nachstehend wird eine bevorzugte Ausführungsform der Erfindung anhand der Zeichnungen im einzelnen beschrieben. Es zeigen:Below is a preferred one embodiment the invention with reference to the drawings described in detail. It demonstrate:

1 eine schematische Seitenansicht eines Kraftfahrzeugs mit aufgeschnittener Fahrgastzelle; 1 a schematic side view of a motor vehicle with a cut open passenger compartment;

2 eine perspektivische Ansicht eines Kraftfahrzeugsitzes mit einem angedeuteten, einen Sitzbenutzer umströmenden Luftstrom; 2 a perspective view of a motor vehicle seat with an indicated, flowing around a seat user air flow;

3 eine perspektivische Ansicht des Kraftfahrzeugsitzes nach 2. 3 a perspective view of the motor vehicle seat after 2 ,

In einem Kraftfahrzeug sind sowohl die Front- als auch die Fondsitze über Schlauchleitungen 5a mit einer Klimaanlage 5 verbunden. Die Schlauchleitungen 5a führen den klimatisierten Luftstrom jeweils sowohl einem Sitzteil 1 als auch einer mit einer Kopfstütze 3 versehenen Rückenlehne 2 und Armlehnen 4 eines jeden Kraftfahrzeugsitzes zu.In a motor vehicle, both the front and the rear seats are via hose lines 5a with air conditioning 5 connected. The hose lines 5a lead the air-conditioned air flow to both a seat part 1 as well as one with a headrest 3 provided backrest 2 and armrests 4 of every motor vehicle seat.

Wie aus 2 ersichtlich, wird der dem Sitzteil 1 zugeführte Luftstrom zwischen in einer Sitzteiloberfläche 1a vorgesehenen Polsterbereichen 1c und in Seitenwulsten 1b angeordneten Luftausblasdüsen 1d aufgeteilt. Die Luftausblasdüsen 1d sind in einer Reihe entlang der Seitenkanten der Sitzteiloberfläche 1a angeordnet. Der zur Rückenlehne 2 geführte Luftstrom wird in gleicher Weise auf luftdurchlässige Polsterbereiche 2c und Luftausblasdüsen 2d verteilt. Während die Polsterbereiche 2c in den Kontaktflächen der Rückenlehne 2 mit dem Rücken des Sitzbenutzers vorgesehen sind, tragen die Seitenwulste 2b der Rückenlehne 2 die Luftausblasdüsen 2d in einer senkrecht verlaufenden Reihe am seitlichen Rand der Rückenlehnenoberfläche 2a.How out 2 can be seen, the seat part 1 supplied air flow between in a seat part surface 1a provided upholstery areas 1c and in side beads 1b arranged air outlet nozzles 1d divided up. The air outlet nozzles 1d are in a row along the side edges of the seat part surface 1a arranged. The one for the backrest 2 guided air flow is applied in the same way to air-permeable upholstery areas 2c and air outlet nozzles 2d distributed. While the upholstery areas 2c in the contact areas of the backrest 2 are provided with the back of the seat user, wear the side beads 2 B the backrest 2 the air outlet nozzles 2d in a vertical row on the side edge of the backrest surface 2a ,

Die Kopfstütze 3 ist mit Kopfstützenstangen 3a an der Rükkenlehne 2 höhenverstellbar gelagert. Schlauchleitungen 5a sind durch das Zentrum der Kopfstützenstangen 3a bis in die Kopfstütze 3 verlegt und münden in Luftausblasdüsen 3b an der Vorderseite der Kopfstütze 3. Der Kraftfahrzeugsitz weist außerdem zwei Armlehnen 4 auf, an deren einander zugewandten Seitenflächen 4a, wie aus 3 ersichtlich, zusätzliche Luftausblasdüsen 4b vorgesehen sind. Diese Luftausblasdüsen 4b tragen zur Vervollständigung des den Sitzbenutzer umhüllenden Luftmantels bei. Die Schlauchleitungen können durch die Drehgelenke der Armlehnen 4 geführt sein.The headrest 3 is with headrest bars 3a on the backrest 2 height adjustable. hose lines 5a are through the center of the headrest bars 3a down to the headrest 3 installed and flow into air outlet nozzles 3b at the front of the headrest 3 , The motor vehicle seat also has two armrests 4 on the side surfaces facing each other 4a how out 3 visible, additional air outlet nozzles 4b are provided. These air vents 4b contribute to the completion of the air jacket enveloping the seat user. The hose lines can pass through the swivel joints of the armrests 4 be led.

Wie insbesondere 2 zeigt, wird ein Sitzbenutzer durch die aus den Luftausblasdüsen 1d, 2d und 3b austretende Luft einerseits und durch die aus den Polsterbereichen 1c und 2c austretenden Luftströme andererseits fast vollständig umhüllt, so daß er von der den Fahrgastraum im übrigen füllenden, aufgeheizten Luft weitgehend isoliert ist. Da diese den Sitzbenutzer umgebende Luft nur einen Bruchteil der im Fahrgastraum insgesamt befindlichen Luftmenge ausmacht, tritt die Kühlwirkung unmittelbar nach Einschalten der Klimaanlage 5 ein. Auch die Kontaktflächen zwischen Sitzbenutzer und Rückenlehne 2 bzw. Sitzteil 1 werden durch die sie durchströmende, temperierte Luft schnell gekühlt. Außerdem tritt durch diese Luftströmung auch eine gewisse Isolierung zwischen Sitzbenutzer und Rückenlehnenoberfläche 2a bzw. Sitzteiloberfläche 1a ein. Der vorstehend beschriebene Luftmantel entfaltet seine vorteilhafte Wirkung selbstverständlich auch bei Erwärmen eines stark unterkühlten Fahrgastinnenraums und Kraftfahrzeugsitzes.How in particular 2 shows a seat user through the out of the air outlet nozzles 1d . 2d and 3b escaping air on the one hand and through the upholstery areas 1c and 2c escaping air currents on the other hand almost completely enveloped so that it is largely isolated from the heated air filling the passenger compartment. Since this air, which surrounds the seat user, only makes up a fraction of the total amount of air in the passenger compartment, the cooling effect occurs immediately after the air conditioning system is switched on 5 on. Also the contact areas between the seat user and the backrest 2 or seat part 1 are quickly cooled by the tempered air flowing through them. In addition, this air flow also creates a certain amount of insulation between the seat user and the backrest surface 2a or seat part surface 1a on. The air jacket described above, of course, also has its advantageous effect when a strongly undercooled passenger compartment and motor vehicle seat are heated.
