Abstract
Fahrzeugsitz, insbesondere Fondsitz, mit einer Rückenlehne (12), die ein Lehnenpolster (20) mit einer luftdurchflutbaren Ventilationsschicht (24) aufweist, und mit mindestens einem Ventilator (29) zur Polsterbelüftung, der Luft von der Rückseite des Lehnenpolsters (20) ansaugt und in die Ventilationsschicht (24) einbläst, dadurch gekennzeichnet, dass die Ventilationsschicht (24) mittels einer in Sitzquerrichtung verlaufenden Luftbarriere (31) in einen unteren Abschnitt (241) und einen oberen Abschnitt (242) unterteilt ist und mindestens ein erster Ventilator (29) dem unteren Abschnitt (241) und mindestens ein zweiter Ventilator (30) dem oberen Abschnitt (242) zugeordnet ist, wobei der zweite Ventilator (30) in zur Luftförderrichtung des ersten Ventilators (29) entgegengesetzter Luftförderrichtung arbeitet.Vehicle Seat, in particular rear seat, with a backrest (12), which is a backrest cushion (20) with an air-permeable ventilation layer (24), and with at least one fan (29) for cushion ventilation, the Air from the back the backrest cushion (20) sucks and into the ventilation layer (24) blows, characterized in that the ventilation layer (24) by means of an air barrier (31) extending in the seat transverse direction into one divided lower portion (241) and an upper portion (242) and at least one first fan (29) is the lower section (241) and at least a second fan (30) the upper section (242) is assigned, wherein the second fan (30) in to the air conveying direction of the first fan (29) of opposite air conveying direction is working.
Description
Die Erfindung betrifft einen Fahrzeugsitz gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a vehicle seat according to the preamble of the claim 1.
Zur Erzielung eines hohen Sitzklimakomforts sind solche Fahrzeugsitze mit einer sog. aktiven Sitzbelüftung ausgestattet, bei welcher Luft aus dem Fahrgastraum angesaugt und durch die Polster von Sitzkissen und Rückenlehne hindurchgeblasen wird, um dann teilweise über den luftdurchlässigen Polsterbezug zur der Vorderseite des Sitzes hin auszutreten. Diese Luft führt einerseits Feuchte und Wärme aus dem Polster ab und kühlt andererseits die erwärmten Oberflächen des Polsters.to Achieving a high seat climate comfort are such vehicle seats with a so-called active seat ventilation equipped, in which air sucked from the passenger compartment and blown through the upholstery of seat cushion and backrest is then partially over the air-permeable Cushion cover to the front of the seat to exit. These Air leads on the one hand moisture and heat the pad and cools on the other hand the heated ones surfaces of the upholstery.

Bei Fondsitzen ist die Rückenlehne unmittelbar an der Rückwand des Fahrgastraums angeordnet, die den Fahrgastraum vom Kofferraum trennt. In einigen Kraftfahrzeugen sind im Kofferraum im Bereich der Rück- oder Trennwand eine Vielzahl von Aggregaten und elektrische Steuergeräte installiert, die relativ viel Wärme abgeben und somit den noch zwischen der Rückenlehne und der Rückwand des Fahrgastraums vorhandenen Zwischenraum aufheizen. Für die aktive Sitzbelüftung, die Luft aus dem Zwischenraum ansaugt und in die Ventilationsschicht des Lehnenpolsters einbläst, steht dann nur noch relativ warme Ansaugluft zur Verfügung, so dass eine ausreichende Sitzkühlung nicht erreicht werden kann. Dem Sitzbenutzer des Fondsitzes fehlt das den Sitzklimakomfort ausmachende Frischegefühl beim Sitzen.at Rear seats is the backrest directly on the back wall arranged the passenger compartment, the passenger compartment from the trunk separates. In some automobiles are in the trunk in the area the return or partition installed a variety of units and electrical control units, the relatively much heat and thus the still between the backrest and the rear wall of the passenger compartment heat up existing gap. For active seat ventilation, the Air from the space sucks and into the ventilation layer of the Backrest pad inflates, is then only relatively warm intake air available, so that adequate seating cooling can not be achieved. The seat user of the fund seat is missing the freshness of the seat climate when sitting.
Der Erfindung liegt die Aufgabe zugrunde, bei einem Fahrzeugsitz der eingangs genannten Art die aktive Sitzbelüftung so zu verändern, dass auch bei Verwendung des Fahrzeugsitzes als Fondsitz mit Einbau an der Rückwand des Fahrgastraums ausreichend frische Luft die Ventilationsschicht des Lehnenpolsters durchströmt und so auch bei einem Fondsitz vor warmer Fahrgastraum-Rückwand der gewünschte Sitzklimakomfort erreicht wird.Of the Invention is based on the object in a vehicle seat of the type mentioned above to change the active seat ventilation so that also when using the vehicle seat as a rear seat with installation the back wall of the passenger compartment sufficient fresh air the ventilation layer flows through the backrest cushion And so even with a rear seat in front of warm passenger compartment rear wall, the desired seat climate comfort is reached.
Die Aufgabe ist erfindungsgemäße durch die Merkmale des Anspruchs 1 gelöst.The Task is inventive by the features of claim 1 solved.
Der erfindungsgemäße Fahrzeugsitz hat den Vorteil, dass der mindestens eine, dem oberen Ventilationsschichtabschnitt zugeordnete zweite Ventilator aufgrund seiner gegenüber dem mindestens einen ersten Ventilator umgekehrten Luftförderrichtung Frischluft durch den Polsterbezug und die Luftführungs- oder Ventilationsschicht hindurch in den aufgeheizten Lehnenrückraum transportiert, so dass der dem unteren Ventilationsschichtabschnitt zugeordnete mindestens eine erste Ventilator seinerseits deutlich kühlere Luft in die Ventilationsschicht einzublasen vermag. Dadurch wird das Lehnenpolster insgesamt besser und mit wesentlich kühlerer Luft durchlüftet, was zu einer Verbesserung des Sitzkomforts führt. Der Sitzkomfortgewinn wird mit nur durch den zusätzlichen zweiten Ventilator bedingten, geringen Mehrkosten erzielt und erfordert keine konstruktive Umgestaltung des Fahrzeugsitzes, so dass das Sitzkonzept für die Vordersitze auch für die Fondsitze unverändert beibehalten werden kann. Da häufig in der Rückenlehne schon mehrere Ventilatoren zur Sitzbelüftung vorhanden sind, die gleichmäßig über das Lehnenpolster verteilt sind, entfallen selbst diese geringen Mehrkosten, da die Förderrichtung der dem oberen Ventilationsschichtabschnitt zugeordneten Ventilatoren lediglich umgekehrt werden muss, diese Ventilatoren also nur um 180° gewendet eingebaut werden müssen.Of the Vehicle seat according to the invention has the advantage that the at least one, the upper ventilation layer section associated second fan due to its relative to the at least a first fan reverse air conveying direction through fresh air the upholstery and the airflow or ventilation layer transported through into the heated backrest back space, such that the one associated with the lower ventilation layer section at least one first fan in turn significantly cooler air into the ventilation layer is able to blow. This will do that Lean upholstery better overall and with much cooler air aerated which leads to an improvement in seating comfort. The seating comfort gain will be with only by the additional second fan conditional, low additional costs and requires no constructive redesign of the vehicle seat, so that the Seat concept for the front seats also for the rear seats unchanged can be maintained. As often in the backrest There are already several fans for seat ventilation, evenly across the backrest cushion even these low additional costs are eliminated, as the conveying direction the fans associated with the upper ventilation layer section only has to be reversed, these fans so only to 180 ° turned must be installed.
Vorteilhafte Ausführungsformen des erfindungsgemäßen Fahrzeugsitzes mit zweckmäßigen Weiterbildungen und Ausgestaltungen der Erfindung sind in den weiteren Patentansprüchen angegeben.advantageous embodiments the vehicle seat according to the invention with appropriate training and embodiments of the invention are set forth in the further claims.
