Die Druckschrift US 5 137 329 A offenbart eine Sitzvorrichtung mit einer einstellbaren, zur Integration in einer Sitzkomponente vorgesehenen Stützeinheit, die zwei pneumatische Stützmittel und ein verstellbares mechanisches Stützmittel aufweist. Das mechanische Stützmittel ist mit einem elastischen Band gehalten, das durch Durchbrüche in dem mechanischen Stützmittel geführt und mit Befestigungsmitteln an dem mechanischen Stützmittel befestigt ist. Das verstellbare, mechanische Stützmittel kann mittels wechselnder Änderungen eines Mediendrucks in den beiden pneumatischen Stützmitteln in seiner Neigung sowohl mit einer Oberkante nach vorne (oberes pneumatisches Stützmittel aufgebläht, unteres pneumatisches Stützmittel entleert) als auch mit der Oberkante nach hinten (oberes pneumatisches Stützmittel entleert, unteres pneumatisches Stützmittel aufgebläht) ausgerichtet werden. Zudem ist es möglich, das mechanische Stützmittel in Zwischenpositionen auszurichten. Demnach ist das mechanische Stützmittel von einer beweglich - jedoch nicht schwenkbar - gelagerten Klappe gebildet.The publication US 5 137 329 A discloses a seat apparatus having an adjustable support unit for integration into a seat component, which has two pneumatic support means and an adjustable mechanical support means. The mechanical support means is held by an elastic band which passes through apertures in the mechanical support means and is fastened to the mechanical support means by fasteners. The adjustable mechanical support means may be tilted by alternating changes of media pressure in the two pneumatic support means with both an upper edge forward (upper pneumatic support means inflated, lower pneumatic support means deflated) and upper edge rearward (upper pneumatic support means deflated, lower pneumatic proppant inflated). In addition, it is possible to align the mechanical support means in intermediate positions. Accordingly, the mechanical support means of a movable - but not hinged - stored flap formed.

Vorteile der ErfindungAdvantages of the invention

Die Erfindung geht aus von einer Sitzvorrichtung mit einer einstellbaren, zur Integration in einer Sitzkomponente vorgesehenen Stützeinheit, die wenigstens ein pneumatisches Stützmittel und wenigstens ein mechanisches Stützmittel aufweist.The invention is based on a seat device with an adjustable, for integration into a seat component provided support unit having at least one pneumatic support means and at least one mechanical support means.

Es wird vorgeschlagen, dass das mechanische Stützmittel von einer schwenkbar gelagerten Klappe gebildet ist und sich nahezu über eine gesamte Breite einer Rückenlehne erstreckt und in seinem einem Sitzboden abgewandten Randbereich um eine Schwenkachse an einem Rückenlehnenrahmen schwenkbar gelagert ist. Dabei soll unter einem "mechanischen Stützmittel" insbesondere ein von einem Körper gebildetes Mittel verstanden werden, das insbesondere gegenüber einem biegeweichen Bauteil, wie einer biegeweichen Hülle eines pneumatischen Stützmittels und eines biegeweichen Stoffbezugs, dazu geeignet ist und insbesondere auch dazu vorgesehen ist, quer zu eine Flächenerstreckung Funktionskräfte zu übertragen. Das von dem Körper gebildete Mittel ist dabei quer zu seiner Flächenerstreckung vorteilhaft biegesteif und/oder besonders bevorzugt elastisch verformbar ausgebildet, insbesondere durch das Gewicht eines Passagiers im Anwendungsfall um mehr als einen Millimeter. Durch eine elastische Verformbarkeit können vorteilhafte Anpassungen und Übergänge erreicht werden. Dabei kann das mechanische Stützmittel aus verschiedenen, dem Fachmann als sinnvoll erscheinenden Werkstoffen hergestellt sein, wie insbesondere aus Verbundwerkstoffen, wie Kohlfaserwerkstoffe, Glasfaserwerkstoffe, und/oder auch aus einem oder mehreren Kunststoffen, beispielsweise indem dieses in einem Mehrkomponentenspritzverfahren hergestellt wird, usw. Ferner soll unter "vorgesehen" speziell ausgestattet und/oder ausgebildet verstanden werden.It is proposed that the mechanical support means is formed by a pivotally mounted flap and extends almost over an entire width of a backrest and in its edge remote from a seat bottom is pivotally mounted about a pivot axis on a backrest frame. In this case, a "mechanical support means" is to be understood as meaning, in particular, an agent formed by a body, which in particular faces a flexurally soft component, such as a flexurally soft shell of a pneumatic support means and a flexible fabric cover, is suitable and in particular also intended to transmit functional forces transversely to a surface extension. The means formed by the body is advantageously formed transversely to its surface extension rigid and / or particularly preferably elastically deformable, in particular by the weight of a passenger in the application by more than a millimeter. By elastic deformability advantageous adjustments and transitions can be achieved. In this case, the mechanical support means may be made of various materials that appear appropriate to those skilled in the art, such as composites, such as carbon fiber materials, glass fiber materials, and / or one or more plastics, for example, by this is produced in a multi-component injection molding, etc. Furthermore Under "intended" specially equipped and / or trained understood.

Durch eine entsprechende erfindungsgemäße Ausgestaltung können mit kleinen Luftmengen große Verstellungen einfach realisiert werden, und zwar insbesondere dadurch, dass das mechanische Stützmittel von einer schwenkbar gelagerten Klappe gebildet ist. Es können mit geringem Energieaufwand, in kurzen Zeitspannen vorteilhafte Anpassungen realisiert werden. Durch die schwenkbare Lagerung können ferner vorteilhafte Übergänge erreicht werden. Grundsätzlich wären jedoch auch zumindest teilweise translatorisch beweglich geführte mechanische Stützmittel denkbar.By means of a corresponding configuration according to the invention, large adjustments can be easily realized with small amounts of air, in particular by virtue of the fact that the mechanical support means is formed by a pivotably mounted flap. It can be realized with low energy consumption, in short periods advantageous adjustments. By pivoting storage advantageous transitions can also be achieved. In principle, however, at least partially translationally movable guided mechanical support means are conceivable.

Das mechanische Stützmittel kann manuell und/oder über zusätzliche Aktuatoren einstellbar ausgeführt sein. Besonders vorteilhaft ist das pneumatische Stützmittel jedoch mit dem mechanischen Stützmittel gekoppelt und ist zur Betätigung des mechanischen Stützmittels vorgesehen, wodurch zusätzliche, insbesondere schwere Aktuatoren vermieden werden können.The mechanical support means can be designed manually and / or adjustable by additional actuators. However, the pneumatic support means is particularly advantageously coupled to the mechanical support means and is provided for actuating the mechanical support means, whereby additional, in particular heavy actuators can be avoided.

In einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, dass das mechanische Stützmittel in Richtung zumindest einer Flächenerstreckung eine sich verändernde Steifigkeit, insbesondere Biegesteifigkeit aufweist, wodurch gezielt über die Flächenerstreckungen unterschiedliche Abstützwirkungen erzielt werden können.In a further embodiment of the invention, it is proposed that the mechanical support means in the direction of at least one surface extension have a varying rigidity, in particular flexural rigidity, whereby different supporting effects can be achieved in a targeted manner over the surface extensions.

Ferner wird eine Sitzvorrichtung vorgeschlagen, die eine einstellbare, zur Integration in einer Sitzkomponente vorgesehene Stützeinheit umfasst, die wenigstens ein verstellbares mechanisches Stützmittel umfasst, wobei die Sitzvorrichtung eine Stelleinheit aufweist, die dazu vorgesehen ist, zumindest teilautomatisiert die Stützeinheit abhängig von einer Kenngröße einzustellen. Abhängig von der Kenngröße kann eine vorteilhafte Einstellung realisiert und der Komfort kann erhöht werden. Durch die Kombination von wenigstens einem mechanischen Stützmittel und wenigstens einem pneumatischen Stützmittel können vorteilhaft verschiedene Abstützwirkungen erzielt und es kann insbesondere ein vorteilhaft großer Einstellbereich erreicht werden, so dass verschiedene Einstellungen vorteilhaft abhängig von wenigstens einer Kenngröße realisiert werden können.Further, a seat device is proposed, which comprises an adjustable, provided for integration in a seat component support unit comprising at least one adjustable mechanical support means, wherein the seat device has an actuating unit which is provided to adjust at least partially automated, the support unit depending on a characteristic. Depending on the characteristic, an advantageous setting can be realized and the comfort can be increased. Due to the combination of at least one mechanical support means and at least one pneumatic support means, different support effects can advantageously be achieved and, in particular, an advantageously large adjustment range can be achieved, so that different settings can advantageously be realized depending on at least one parameter.

Dabei kann die Stelleinheit die Stützeinheit abhängig von verschiedenen, dem Fachmann als sinnvoll erscheinenden Kenngrößen einstellen, besonders vorteilhaft jedoch abhängig von einer Sitzkomponentenstellung und insbesondere abhängig von einer Rückenlehnenstellung. Sich wesentlich verändernde Anforderungen an die Stützeinheit durch die Veränderung einer Lage einer Sitzkomponente und insbesondere der Lage einer Rückenlehne kann damit vorteilhaft Rechnung getragen werden.In this case, the setting unit can adjust the support unit depending on various parameters that appear appropriate to those skilled in the art, but particularly advantageously depending on a seat component position and in particular depending on a backrest position. Significantly changing requirements for the support unit by changing a position of a seat component and in particular the position of a backrest can thus be advantageously taken into account.

Vorzugsweise bildet die Stützeinheit eine einstellbare Lordosenstütze, so dass insbesondere im unteren Bereich einer Rückenlehne ein vorteilhaft großer, insbesondere ein von einer Kenngröße abhängiger Einstellbereich erreicht werden kann.Preferably, the support unit forms an adjustable lumbar support, so that, in particular in the lower region of a backrest, an advantageously large adjustment range, in particular a setting range dependent on a parameter, can be achieved.

In einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, dass die Stützeinheit zumindest zwei pneumatische Stützmittel zur Erzielung differierender Einstellungen aufweist, wodurch konstruktiv einfach unterschiedliche Stützwirkungen erzielt werden können, und zwar insbesondere, wenn die pneumatischen Stützmittel Koppelstellen zum mechanischen Stützmittel aufweisen, die unterschiedlich weit von einer Schwenkachse des mechanischen Stützmittels beabstandet sind.In a further embodiment of the invention it is proposed that the support unit has at least two pneumatic support means to achieve different settings, which structurally simple different support effects can be achieved, in particular if the pneumatic support means coupling points to the mechanical support means, the different distances from one Pivot axis of the mechanical support means are spaced.

Ferner wird vorgeschlagen, dass die Stelleinheit eine Ventileinheit umfasst, wodurch über die Steuerung und/oder Regelung einer Luftmenge in einem pneumatischen Stützmittel einfach eine Verstellung realisiert werden kann, und zwar indem über die Ventileinheit Luft zugeführt und/oder insbesondere indem über die Ventileinheit Luft ab einer bestimmten Sitzkomponentenstellung abgelassen bzw. ein pneumatisches Stützmittel entlüftet wird.It is also proposed that the setting unit comprises a valve unit, which can be easily realized on the control and / or regulation of an amount of air in a pneumatic support means an adjustment, namely by supplied via the valve unit air and / or in particular by the air via the valve unit a certain seat component position drained or a pneumatic proppant is vented.

Die erfindungsgemäße Lösung eignet sich bei sämtlichen, dem Fachmann als sinnvoll erscheinenden Sitzen, wie bei Sitzen für Reisebusse, Schiffsfähren, Säle, Kongresshallen, jedoch vorteilhaft bei Fahrzeugsitzen und besonders vorteilhaft bei Flugzeugsitzen.The solution according to the invention is suitable for all seats that appear reasonable to the person skilled in the art, such as seats for coaches, boat ferries, halls, congress halls, but advantageous for vehicle seats and particularly advantageous for aircraft seats.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Figur 1 zeigt einen Flugzeugsitz mit einer erfindungsgemäßen Sitzvorrichtung, die eine in einer von einer Rückenlehne gebildeten Sitzkomponente 10 integrierte, als Lordosenstütze ausgebildete Stützeinheit 12 aufweist. Die im unteren Bereich der Rückenlehne unterhalb eines Bezugs 34 der Rückenlehne angeordnete Stützeinheit 12 weist drei pneumatische, von Luftsäcken gebildete Stützmittel 14, 16, 18 und ein von einer schwenkbar gelagerten, einzelnen Klappe gebildetes verstellbares mechanisches Stützmittel 20 auf, das aus einem Kohlefaserverbundwerkstoff hergestellt ist. Das mechanische Stützmittel 20 erstreckt sich nahezu über die gesamte Breite der Rückenlehne, ist in seinem oberen bzw. seinem einem Sitzboden 36 abgewandten Randbereich um eine Schwenkachse 26 an einem Rückenlehnenrahmen 28 schwenkbar gelagert und weist hierfür sich seitlich über Rahmenelemente des Rückenlehnenrahmens 28 erstreckende Flügel 30 auf (Figur 2). Das im Wesentlichen unmittelbar oberhalb des Sitzbodens 36 abschließende mechanische Stützmittel 20 ist um eine Längsachse 38 der Rückenlehne und um eine Querachse 40 der Rückenlehne gekrümmt ausgebildet, und zwar ist das mechanische Stützmittel 20 um die Querachse 40 in die von einer im Rückenlehnenrahmen 28 angeordneten Rückenlehnenbespannung 32 abgewandte Richtung gewölbt ausgeführt und ist um die Längsachse 38 in Richtung der Rückenlehnenbespannung 32 gewölbt ausgeführt, wodurch eine vorteilhafte ergonomische Anpassung erreicht wird (Figuren 2 und 3). FIG. 1 shows an aircraft seat with a seat device according to the invention, which has a built in a seat back formed by a seat component 10, designed as a lumbar support unit 12. The supporting unit 12, which is arranged in the lower region of the backrest below a cover 34 of the backrest, has three pneumatic support means 14, 16, 18 formed by air bags and an adjustable mechanical support means 20 formed by a pivotably mounted individual flap and made of a carbon fiber composite material , The mechanical support means 20 extends almost over the entire width of the backrest, is pivotally mounted in its upper or a seat bottom 36 facing edge region about a pivot axis 26 on a seat back frame 28 and has for this laterally on frame members of the backrest frame 28 extending wings 30 ( FIG. 2 ). The substantially immediately above the seat bottom 36 final mechanical support means 20 is formed around a longitudinal axis 38 of the backrest and curved about a transverse axis 40 of the backrest, namely, the mechanical support means 20 about the transverse axis 40 in the arranged in the back frame 28 backrest cover 32nd executed curved away direction and is curved around the longitudinal axis 38 in the direction of the backrest cover 32, whereby an advantageous ergonomic adaptation is achieved ( Figures 2 and 3 ).

Die drei pneumatischen Stützmittel 14, 16, 18 sind zwischen der Rückenlehnenbespannung 32 und dem mechanischen Stützmittel 20 angeordnet, sind mit dem mechanischen Stützmittel 20 über jeweils eine Koppelstelle gekoppelt und sind zur Betätigung des mechanischen Stützmittels 20 vorgesehen (Figuren 2 bis 5). Das schlauchartig ausgebildete pneumatische Stützmittel 14 ist im oberen Bereich d.h. im Bereich der Schwenkachse 26 angeordnet, erstreckt sich parallel zur Schwenkachse 26 und weist kurz unterhalb der Schwenkachse 26 eine sich parallel zur Schwenkachse 26 erstreckende Koppelstelle mit dem mechanischen Stützmittel 20 auf.The three pneumatic support means 14, 16, 18 are arranged between the backrest cover 32 and the mechanical support means 20, are coupled to the mechanical support means 20 via a respective coupling point and are provided for actuating the mechanical support means 20 (FIG. FIGS. 2 to 5 ). The tube-like pneumatic support means 14 is arranged in the upper region, ie in the region of the pivot axis 26, extends parallel to the pivot axis 26 and has shortly below the pivot axis 26 a parallel to the pivot axis 26 extending coupling point with the mechanical support means 20.

Die nierenförmig ausgebildeten pneumatischen Stützmittel 16, 18 sind unterhalb d.h. auf einer der Schwenkachse 26 abgewandten Seite des pneumatischen Stützmittels 14 in einem linken und einem rechten Bereich der Rückenlehne angeordnet und sind im unteren Bereich des mechanischen Stützmittels 20 über Koppelstellen mit demselben gekoppelt. Die Koppelstellen der pneumatischen Stützmittel 16, 18 sind damit weiter von der Schwenkachse 26 beabstandet als die Koppelstelle des pneumatischen Stützmittels 14.The kidney-shaped pneumatic support means 16, 18 are below, i. arranged on a side facing away from the pivot axis 26 of the pneumatic support means 14 in a left and a right region of the backrest and are coupled in the lower region of the mechanical support means 20 via coupling points with the same. The coupling points of the pneumatic support means 16, 18 are thus further spaced from the pivot axis 26 as the coupling point of the pneumatic support means fourteenth

Das mechanische Stützmittel 20 ist quer zu seiner Hauptflächenerstreckung elastisch verformbar und weist in seiner Flächenerstreckung 22, d.h. in Richtung der Längsachse 38 der Rückenlehne, eine sich kontinuierlich verändernde Biegesteifigkeit auf, und zwar nimmt die Biegesteifigkeit vom oberen Bereich des mechanischen Stützmittels 20 in Richtung zum unteren, dem Sitzboden 36 zugewandten Bereich des mechanischen Stützmittels 20 kontinuierlich zu. Hierzu ist das mechanische Stützmittel 20 im oberen Bereich bzw. im Bereich der Schwenkachse 26 dünnwandiger und damit mit einer kleineren Biegesteifigkeit und im unteren bzw. im von der Schwenkachse 26 abgewandten Bereich dickwandiger und damit mit einer größeren Biegesteifigkeit ausgeführt, wodurch im oberen Bereich des mechanischen Stützmittels 20 eine besonders vorteilhafte Anpassbarkeit und im unteren Bereich des Stützmittels 20 eine vorteilhafte Kraftübertragung erreicht werden kann.The mechanical support means 20 is elastically deformable transversely to its major surface extension and has in its surface extension 22, ie in the direction of the longitudinal axis 38 of the backrest, a continuously changing flexural rigidity, namely, the flexural rigidity increases from the upper region of the mechanical support means 20 towards the lower . the seat bottom 36 facing portion of the mechanical support means 20 to continuously. For this purpose, the mechanical support means 20 in the upper region or in the region of the pivot axis 26 thin-walled and thus with a smaller bending stiffness and in the lower or in the area facing away from the pivot axis 26 thick-walled and thus executed with a greater bending stiffness, which in the upper part of the mechanical Support means 20 a particularly advantageous adaptability and in the lower region of the support means 20, an advantageous power transmission can be achieved.

Ferner weist die Sitzvorrichtung eine Stelleinheit 24 mit einer Ventileinheit 46 auf, die die dazu vorgesehen ist, teilautomatisiert die Stützeinheit 12 abhängig von einer Rückenlehnenstellung einzustellen.Furthermore, the seat device has an actuating unit 24 with a valve unit 46, which is intended to partially automatically adjust the support unit 12 as a function of a backrest position.

Ist die Rückenlehne in ihrer aufrechten Stellung bzw. in einer einem Flugzeugstart und einer Flugzeuglandung zugeordneten Stellung, kann von einem Passagier über eine nicht näher dargestellte Bedieneinheit mittels einer elektrischen Pumpe 42 über die Ventileinheit 46 der Stelleinheit 24 das pneumatische Stützmittel 14 gefüllt und auch entleert und damit das mechanische Stützmittel 20 betätigt werden (Figur 4). Anstatt oder zusätzlich zur elektrischen Pumpe 42 ist auch eine Handpumpe denkbar, die beispielsweise als Einheit, insbesondere als Hebeleinheit 48, im Bereich des Sitzbodens 36 integriert sein kann oder auch als einfacher Handblasebalg 50 ausgeführt sein kann, wie dies in den Figuren 1, 4 und 5 gestrichelt angedeutet ist.If the backrest is in its upright position or in a position assigned to an aircraft takeoff and landing, the pneumatic support means 14 can be filled and also emptied by a passenger via an operating unit (not shown) by means of an electric pump 42 via the valve unit 46 of the setting unit 24 so that the mechanical support means 20 are actuated ( FIG. 4 ). Instead of or in addition to the electric pump 42, a hand pump is conceivable, which may be integrated as a unit, in particular as a lever unit 48, in the region of the seat bottom 36 or may be designed as a simple hand bellows 50, as shown in the FIGS. 1 . 4 and 5 indicated by dashed lines.

Durch die relativ geringe Eigensteifigkeit des mechanischen Stützmittels 20 im oberen Bereich wird im oberen Bereich desselben eine vorteilhaft flächige Unterstützung der Lordose des Passagiers bewirkt. Das pneumatische Stützmittel 14 ist im einem relativ biegeweichen Bereich mit dem mechanischen Stützmittel 20 gekoppelt, so dass dieses vorteilhaft um das pneumatische Stützmittel 14 elastisch verformt werden kann, wie dies in Figur 4 gestrichelt angedeutet ist, und vorteilhaft ein Sitzreferenzpunkt erhalten bleibt.Due to the relatively low inherent rigidity of the mechanical support means 20 in the upper region, an advantageous planar support of the lordosis of the passenger is effected in the upper region thereof. The pneumatic support means 14 is coupled in a relatively flexible region with the mechanical support means 20, so that this can be advantageously elastically deformed about the pneumatic support means 14, as in FIG. 4 is indicated by dashed lines, and advantageously a seat reference point is maintained.

In der aufrechten Stellung der Rückenlehne ist über die Ventileinheit 46 der Stelleinheit 24 eine Verbindung zwischen der Pumpe 42 und den pneumatischen Stützmitteln 16, 18 unterbunden und die pneumatischen Stützmittel 16, 18 sind über die Ventileinheit 46 entlüftet.In the upright position of the backrest a connection between the pump 42 and the pneumatic support means 16, 18 is prevented via the valve unit 46 of the actuator 24 and the pneumatic support means 16, 18 are vented via the valve unit 46.

Wird die Rückenlehne in eine geneigte Stellung gebracht, wird über die Ventileinheit 46 der Stelleinheit 24 eine Verbindung zwischen der Pumpe 42 und den pneumatischen Stützmitteln 16, 18 hergestellt und eine Verbindung zwischen der Pumpe 42 und dem pneumatischen Stützmittel 14 unterbrochen. Ferner wird das pneumatische Stützmittel 14 entlüftet. Vom Passagier können nunmehr die pneumatischen Stützmittel 16, 18 gefüllt und entleert werden (Figur 5). Werden die pneumatischen Stützmittel 16, 18 gefüllt, drücken dieselben das mechanische Stützmittel 20 in Richtung Passagier und unterstützen den Passagier in dessen Beckenbereich, so dass eine angenehme Liegeposition eingenommen werden kann. Die Stellung der Rückenlehne wird dabei über eine mechanische Einheit 44 der Stelleinheit 24 sensiert und eine Stellbewegung wird von der Rückenlehne über die mechanische Einheit 44 auf die Ventileinheit 46 der Stelleinheit 24 übertragen. Durch die mechanische Sensierung und die mechanische Übertragung der Stellbewegung von der Rückenlehne mittels der mechanischen Einheit 44 auf die Ventileinheit 46 können zusätzliche Aktuatoren eingespart werden. Grundsätzlich wäre jedoch auch denkbar, dass die Stellung der Rückenlehne elektronisch detektiert und/oder dass eine Stellbewegung mittels eines zusätzlichen Aktuators erzeugt wird.If the backrest is brought into an inclined position, a connection between the pump 42 and the pneumatic support means 16, 18 is made via the valve unit 46 of the actuator 24 and a connection between the pump 42 and the pneumatic support means 14 is interrupted. Furthermore, the pneumatic support means 14 is vented. From the passenger now the pneumatic support means 16, 18 can be filled and emptied ( FIG. 5 ). When the pneumatic support means 16, 18 are filled, they push the mechanical support means 20 in the direction of the passenger and support the passenger in the pelvic area, so that a comfortable lying position can be assumed. The position of the backrest is sensed via a mechanical unit 44 of the actuator 24 and an actuating movement is from the backrest on the mechanical unit 44 to the valve unit 46 of the Actuator 24 transmitted. Due to the mechanical sensing and the mechanical transmission of the adjusting movement of the backrest by means of the mechanical unit 44 on the valve unit 46 additional actuators can be saved. In principle, however, it would also be conceivable that the position of the backrest is detected electronically and / or that an adjusting movement is generated by means of an additional actuator.

Wird die Rückenlehne von dem Passagier wieder in ihre aufrechte Stellung gebracht, wird mittels einer mechanischen Einheit 44 eine Stellbewegung von der Rückenlehne auf die Ventileinheit 46 der Stelleinheit 24 übertragen und die pneumatischen Stützmittel 16, 18 werden entlüftet bzw. wird Luft aus den pneumatischen Stützmitteln 16, 18 abgelassen, wodurch gewährleistet wird, dass ein Sitzreferenzpunkt erhalten bleibt. Zudem wird die Pumpe 42 wieder mit dem pneumatischen Stützmittel 14 verbunden. Die pneumatischen Stützmittel 16, 18 sind damit ausschließlich geneigten Stellungen der Rückenlehne zugeordnet, während das pneumatische Stützmittel 14 ausschließlich einer aufrechten Stellung zugeordnet ist, wodurch stets nur geringe Luftmengen erforderlich sind. Grundsätzlich sind jedoch auch andere, dem Fachmann als sinnvoll erscheinende Zuordnungen denkbar, insbesondere könnte das Stützmittel 14 auch bei einer geneigten Stellung der Rückenlehne aufblasbar ausgeführt sein, beispielsweise um eine zusätzliche Stützwirkung zu erzielen.If the backrest is returned to its upright position by the passenger, an actuating movement is transmitted from the backrest to the valve unit 46 of the setting unit 24 by means of a mechanical unit 44 and the pneumatic support means 16, 18 are vented or air is removed from the pneumatic support means 16 18, which ensures that a seat reference point is maintained. In addition, the pump 42 is again connected to the pneumatic support means 14. The pneumatic support means 16, 18 are thus assigned exclusively inclined positions of the backrest, while the pneumatic support means 14 is associated exclusively with an upright position, whereby always only small amounts of air are required. In principle, however, other assignments that appear reasonable to a person skilled in the art are also conceivable; in particular, the support means 14 could be designed to be inflatable even with an inclined position of the backrest, for example to achieve an additional supporting effect.
