Aus der zum Anmeldetag vorliegender Patentanmeldung noch nicht veröffentlichten Deutschen Patentanmeldung mit dem amtlichen Aktenzeichen 102 43 315.16 und dem Anmeldetag vom 18.09.2002 ist ein Polster mit einem Polsterkern bekannt. Zur Verbesserung des Klimakomforts sind in einer Oberfläche des Polsterkerns voneinander beabstandete, jeweils querschnittskonstante Längs- und Quernuten eingeformt, die zu einer Deckschicht hin offen sind und sich gegenseitig kreuzen. Die beschriebenen Längs- und Quernuten sind dabei als Belüftungskanäle ausgebildet. Zusätzlich sind in dem Polsterkern dessen volle Kerndicke durchdringende Lüftungsschächte vorgesehen, die einerseits in den Kreuzungspunkten von Längs- und Quernuten und andererseits frei an der Außenseite des Polsterkerns münden. Des weiteren kann ein Gebläse zur Beaufschlagung eines zentralen Polsterbereiches mit Luft entweder auf der von der: Deckschicht abgekehrten Seite des Polsterkerns und mit Abstand von diesem oder in einem den Polsterkern vollständig durchdringenden Schacht angeordnet sein.A cushion with a cushion core is known from the German patent application with the official file number 102 43 315.16 and the filing date of September 18, 2002, which was not yet published on the filing date of the patent application. To improve climatic comfort, longitudinal and transverse grooves, which are spaced apart from one another and have a constant cross section, are formed in a surface of the upholstery core and are open towards a cover layer and cross each other. The described longitudinal and transverse grooves are designed as ventilation channels. In addition, the full core thickness penetrating ventilation shafts are provided in the upholstery core, which open out on the one hand in the intersection of longitudinal and transverse grooves and on the other hand freely on the outside of the upholstery core. Furthermore, a blower for supplying air to a central upholstery area can be arranged either on the side of the upholstery core facing away from the cover layer and at a distance therefrom or in a shaft which completely penetrates the upholstery core.
Aus der DE 200 02 447 Ul ist ein Sitzpolster für Fahrzeugsitze, insbesondere für Fahrzeugsitze mit einem Kernteil aus einem Kunststoffschäum bekannt. Das Kernteil weist auf seiner oberen, einer Sitzfläche zugekehrten Seite kanalartige Vertiefungen auf, welche zonale Schwächungen bewirken und da- durch die Sitzfläche entsprechend der erforderlichen Druckverhältnisse gestalten. Grundgedanke ist hierbei eine körpergerechte Unterstützung zu schaffen, welche gleichzeitig ein weiches und angenehmes Sitzempfinden bewirkit . Dabei sind die kanalartigen Vertiefungen und die dadurch gebildeten, verbleibenden Teilflächen des Kernteils in Anpassung an die menschliche Anatomie derart ausgelegt, dass eine optimale Sitzdruckverteilung erreicht wird. Des Weiteren ist vorgesehen, in den kanalartigen Vertiefungen zumindest teilweise eine LuftZirkulation zu ermöglichen. Dabei kann entweder eine passive oder eine aktive Belüftung mit einem zusätzlichen Lüfter vorgesehen sein.DE 200 02 447 U1 discloses a seat cushion for vehicle seats, in particular for vehicle seats with a core part made of a plastic foam. The core part has channel-like depressions on its upper side facing a seat surface, which cause zonal weakenings and by designing the seat according to the required pressure conditions. The basic idea here is to provide support that is tailored to the body, which at the same time brings about a soft and pleasant feeling of sitting. The channel-like depressions and the resulting remaining partial surfaces of the core part are designed to match the human anatomy in such a way that an optimal seat pressure distribution is achieved. Furthermore, it is envisaged to at least partially allow air to circulate in the channel-like depressions. Either passive or active ventilation with an additional fan can be provided.
Aus der DE 33 06 871 AI ist ein Polster mit einer luftdurchlässigen Deckschicht bekannt. Bei dem Polster wird durch Lüftungskanäle beziehungsweise flexible auf dem oder im Kern verlaufende Rohre mit luftdurchlässigen Wänden ein verstärkter Luftaustausch in den Bereichen auf denen man sitzt, lehnt oder liegt erreicht, was einen zu großen Temperaturanstieg der Polsteroberfläche verhindert. Des weiteren ist vorgesehen, die Kanaldichte und einen KanalquerscJαnitt so auf eine Polstergröße bzw. -form abzustimmen, dass eine als bequem empfundene Sitzdruckverteilung erhalten bleibt.From DE 33 06 871 AI a cushion with an air-permeable cover layer is known. With the upholstery, ventilation ducts or flexible pipes running on or in the core with air-permeable walls increase the air exchange in the areas on which you sit, lean or lie, which prevents the temperature of the upholstery surface from rising too much. It is also provided that the channel density and a channel cross-section are matched to a cushion size or shape in such a way that a seat pressure distribution which is perceived as comfortable is retained.
Aus der DE 40 01 207 AI ist ein Fahrzeugsitz mit einem mit einem Polsterüberzug versehenen Polsterkorper bekannt. An der Innenseite des Sitzes ist zwischen Polsteαrkörper und einem Polsterüberzug ein feuchtigkeitsabsorbierendes Material vorgesehen, das die Feuchtigkeit an den Anlacjeflachen des Sitzes, an denen die Körperpartien des Fahrzeuginsassen anliegen, absorbiert und zur Außenseite des Sitzes transportiert. Desweiteren sind im Polsterkörper Ausneh umgen in Form von sackporenartigen Quernuten vorgesehen, du-trch die sich das feutigkeitsabsorbierende Material zur Außenseite des Polsterkörpers erstreckt. Die genannten Ausnehmungen transportieren die anfallende Feuchtigkeit ab und gewährleisten damit ein angenehmes Sitzklima. Die genannten Ausnehτnungen sind dabei im wesentlichen regel- und gleichmäßig über Sitz- bzw. Lehnenfläche des Fahrzeugsitzes verteilt.DE 40 01 207 AI discloses a vehicle seat with a cushion body provided with a cushion cover. Provided on the inside of the seat between the upholstery body and a cushion cover is a moisture-absorbing material which absorbs the moisture on the contact surfaces of the seat, on which the body parts of the vehicle occupant lie, and transports it to the outside of the seat. Furthermore, recesses are provided in the upholstery body in the form of sack-pore-like transverse grooves, through which the moisture-absorbing material extends to the outside of the upholstery body. The recesses mentioned transport away the moisture and thus ensure a comfortable seating climate. The above-mentioned exceptions are included distributed essentially regularly and evenly over the seat or backrest surface of the vehicle seat.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für einen Fahrzeugsitz eingangs erwähnter Art eine verbesserte Ausführungsform anzugeben, bei welcher insbesondere ein besonders hoher Sitzkomfort erreicht wird.The present invention is concerned with the problem of specifying an improved embodiment for a vehicle seat of the type mentioned at the outset, in which, in particular, particularly high seating comfort is achieved.
Diese Aufgabe wird durch den Gegenstand, des unabhängigen Anspruchs gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der abhängigen Ansprüche .This object is achieved by the subject matter of the independent claim. Advantageous refinements are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, bei einem Fahrzeugsitz für ein Kraftfahrzeug, welches einen Polsterkern mit im wesentlichen oberflächenparallelen Lüftungskanälen und quer dazu angeordneten Lüftungsschächten aufweist, eine vorbestimmte Anordnung der Lüftungskanäle und/oder -schachte vorzusehen, welche unterschiedlich stark belüftete Bereiche im Polsterkern definiert und wobei diese Bereiche an einen Lüftungsbedarf eines Standardfahrzeuginsassen angepasst sind. Die Lüftungskanäle laufen im wesentlichen entlang und innenseitig einer Sitz- und/oder Lehnenfläche und weisen einen im wesentlichen konstanten Querschnitt auf . Die Lüftungsschächte, welche ebenfalls jeweils einen konstanten Querschnitt aufweisen, durchdringen den Polsterkern in dessen gesamter Dicke und erstrecken sich von den Lüftungskanälen bis an eine der Sitz- und/oder Lehnenfläche abgekehrte Rückwand. Die Lüftungsschächte münden dabei vorzugsweise in einem Kreuzungspunkt zweier sich kreuzender Lüftungskanäle.The invention is based on the general idea of providing a predetermined arrangement of the ventilation ducts and / or ducts in a vehicle seat for a motor vehicle, which has an upholstery core with essentially surface-parallel ventilation ducts and ventilation ducts arranged transversely thereto, which defines differently ventilated areas in the upholstery core and wherein these areas are adapted to a ventilation requirement of a standard vehicle occupant. The ventilation ducts run essentially along and on the inside of a seat and / or backrest surface and have an essentially constant cross section. The ventilation shafts, which also each have a constant cross section, penetrate the entire thickness of the upholstery core and extend from the ventilation ducts to a rear wall facing away from the seat and / or backrest surface. The ventilation shafts preferably open at a crossing point of two intersecting ventilation ducts.
Die erfindungsgemäße Lösung bietet den großen Vorteil, dass die Lüftungskanäle innerhalb des Polsterkerns nur dort angeordnet sind, wo eine Belüftung auch tatsächlich erforderlich ist. Beispielsweise besteht im unteren Rückenbereich bzw. im Bereich eines menschlichen Sitzbeinhöckers ein erhöhter Lüftungsbedarf, wogegen im Schulterbereich, d.h. im oberen Rückenbereich, ein eher geringer Lüftungsbedarf besteht. Durch die Anpassung des Lüftungssystems aus Lüftungskanälen und Lüftungsschächten an den Lüftungsbedarf eines standardisierten 'Fahrzeuginsassen wird eine deutliche Komfortsteigerung erreicht, welche sich insbesondere dadurch bemerkbar macht, dass die vom Fahrzeuginsassen abgegebene Schwitzfeuchte, welche an unterschiedlichen Stellen des Fahrzeugsitzes unterschiedlich stark abgegeben wird, bedarfsgerecht abgeführt werden kann. Dem Fahrzeuginsassen wird dadurch ein angenehmes und frisches Sitzgefühl vermittelt, was sich positiv auf das Wohlbehagen des Fahrzeuginsassen und in der Folge auch auf die Fahrsicherheit auswirkt.The solution according to the invention offers the great advantage that the ventilation ducts are arranged within the cushion core only where ventilation is actually required. For example, there is an increased need for ventilation in the lower back area or in the area of a human ischial cusp, whereas in the shoulder area, ie in the upper back area, there is a rather low need for ventilation. By The adaptation of the ventilation system from ventilation ducts and ventilation shafts to the ventilation requirements of a standardized ' vehicle occupant achieves a significant increase in comfort, which is particularly noticeable in that the sweat moisture emitted by the vehicle occupant, which is emitted to different locations in the vehicle seat, can be dissipated as required , The vehicle occupant is given a pleasant and fresh seating experience, which has a positive effect on the comfort of the vehicle occupant and, as a result, also on driving safety.
In Bereichen mit größerem Lüftungsbedarf können dabei die Lüftungskanäle und/oder die Lüftungsschächte dichter angeordnet sein und/oder einen größeren Querschnitt aufweisen und dadurch eine erhöhte Entfeuchtungsleistung bewirken. In Bereichen, in denen nur mit einem mäßigen oder geringen Schwitzfeuchteaufkommen zu rechnen ist, können die Lüftungs- kanäle und/oder -schachte einen größeren Abstand voneinander aufweisen und/oder mit einem kleineren Querschnitt ausgebildet werden. Insgesamt bietet die erfindungsgemäße Lösung also den großen Vorteil, dass die Lüftungsleistung des Fahrzeugsitzes an den tatsächlichen Lüftungsbedarf unterschiedlicher Sitzstellen angepasst ist.In areas with a greater need for ventilation, the ventilation ducts and / or the ventilation shafts can be arranged more densely and / or have a larger cross-section and thereby bring about an increased dehumidification performance. In areas in which only a moderate or low amount of sweat moisture is to be expected, the ventilation ducts and / or ducts can be at a greater distance from one another and / or can be designed with a smaller cross section. Overall, the solution according to the invention therefore offers the great advantage that the ventilation performance of the vehicle seat is adapted to the actual ventilation requirements of different seating positions.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist der Lüftungsbedarf an eine Körperdruckverteilung- angepasst. An Stellen mit erhöhtem Körperdruck, beispielsweise im Bereich des menschlichen Sitzbeinhöckers, ist mit einem erhöhten Schwitzfeuchteaufkommen zu rechnen, wogegen in Bereichen mit einem geringen Körperanpreßdruck naturgemäß deutlich weniger Schwitzfeuchte entsteht. Dadurch ist es sinnvoll, den Lüftungsbedarf an eine Körperdruckverteilung anzupassen, in dem beispielsweise die Anordnung der Luftungskanale und/oder der Lüftungsschächte hinsichtlich ihrer Form und Anordnungsdichte auf die Kδrperdruckverteilung abgestimmt wird.. Die Belüftung bzw. die Abführung von Feuchte ist dadurch bedarfsgerecht auf den tatsächlichen Bedarf, ausgelöst durch die menschliche A- natomie abgestimmt .According to a preferred embodiment of the invention, the ventilation requirement is adapted to a body pressure distribution. In places with increased body pressure, for example in the area of the human ischium, an increased amount of perspiration is to be expected, whereas in areas with a low body pressure there is naturally much less perspiration moisture. It makes sense to adapt the ventilation requirement to a body pressure distribution by, for example, coordinating the arrangement of the ventilation ducts and / or the ventilation shafts in terms of their shape and arrangement density with the body pressure distribution the actual need, triggered by human anatomy.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist der Lüftungsbedarf an Körperkontaktstellen angepasst. Auch bei dieser Ausführungsform ist eine bedarfsgerechte und vor allem an die menschliche Anatomie angepasste Entfeuchtung einzelner Sitzbereiche gewährleistet. An Stellen, an denen der Körper des Standardfahrzeuginsassen mit der Sitz- oder Lehnenfläche Kontakt hat, ist normalerweise mit einem deutlich höheren Schwitzfeuchteaufkommen zu rechnen, als an Stellen, an denen kein oder lediglich sporadischer Kontakt zwischen dem Fahrzeuginsassen und der Sitz- oder Lehnenfläche auftritt. An Bereichen, an denen der Fahrzeuginsasse keine Berührung mit der Sitz- oder Lehnenfläche hat, ist zwischen dieser und dem Fahrzeuginsassen eine isolierende, entfeuchtende und gleichzeitig erfrischende Luftschicht, welche selbst bei geringer Strömungsgeschwindigkeit eine ausreichende Belüftung garantiert. An Bereichen mit direktem Körperkontakt hingegen ist die Dicke dieser Luftschicht jedoch stark reduziert und eine Strömungsgeschwindigkeit bzw. eine Zirkulation der Luftschicht nahezu unmöglich. Es erscheint daher äußerst sinnvoll, den Lüftungsbedarf, das heißt die Anordnung der Lüftungskanäle und/oder -schachte, an mögliche Körperkontaktstellen des Standardfahrzeuginsassen mit dem Fahrzeugsitz anzupassen.According to an advantageous development of the invention, the ventilation requirement is adapted to body contact points. This embodiment also ensures that the dehumidification of individual seating areas is tailored to the needs and, above all, adapted to the human anatomy. In places where the body of the standard vehicle occupant comes into contact with the seat or backrest surface, a significantly higher amount of perspiration is normally to be expected than in locations where there is no or only sporadic contact between the vehicle occupant and the seat or backrest surface. In areas where the vehicle occupant has no contact with the seat or backrest surface, there is an insulating, dehumidifying and at the same time refreshing air layer between it and the vehicle occupant, which guarantees sufficient ventilation even at low flow speeds. In areas with direct body contact, on the other hand, the thickness of this air layer is greatly reduced and flow velocity or circulation of the air layer is almost impossible. It therefore appears extremely useful to adapt the ventilation requirement, that is to say the arrangement of the ventilation ducts and / or ducts, to possible body contact points of the standard vehicle occupant with the vehicle seat.
Zweckmäßig kann vorgesehen sein, die Luftungskanale als Kanalgitter auszubilden und Strömungsverbunden zu kreuzen. Ein derartiges Kanalgitter bietet eine gleichmäßige und hinreichende Belüftung aller verbundener Kanäle und gewährleistet dadurch eine für die Belüftung erforderliche Zirkulation im KanalSystem.It can expediently be provided to design the ventilation ducts as duct grids and to cross them in connection with flow. Such a duct grille provides even and sufficient ventilation of all connected ducts and thus ensures the circulation in the duct system required for ventilation.
Entsprechend einer besonders bevorzugten Aus führungsform der erfindungsgemäßen Lösung können die Lüftungskanäle und/oder - schachte nur in Bereichen mit vorgesehener Belüftung angeord- net sein. Derartige Bereiche können beispielsweise über die Sitzdruckverteilung bzw. über die Körperkontaktstellen definiert sein und dadurch sicherstellen, dass die Belüftung des Polsterkerns und damit des Fahrzeugsitzes im wesentlichen auf die Bereiche beschränkt ist, in welchen ein tatsächlicher Lüftungsbedarf vorhanden ist.According to a particularly preferred embodiment of the solution according to the invention, the ventilation ducts and / or ducts can only be arranged in areas with ventilation provided. be nice. Such areas can be defined, for example, via the seat pressure distribution or via the body contact points and thereby ensure that the ventilation of the upholstery core and thus of the vehicle seat is essentially restricted to the areas in which there is an actual need for ventilation.
Gemäß einer bevorzugten Weiterbildung der Erfindung können die Lüftungskanäle und/oder die Lüftungschächte in Bereichen, in denen keine Belüftung vorgesehen ist, verschlossen sein. Dies bietet den großen Vorteil, dass zunächst ein standardisierter Polsterkern zum Einsatz gelangt, bei welchem bei der Herstellung oder nachträglich die entsprechenden Lüftungskanäle und/oder Lüftungsschächte beispielsweise mittels einer Verklebung oder mittels eines Stopfens verschlossen werden. Hierdurch kann beispielsweise eine Bauteilreduzierung und damit ein Kostenvorteil erreicht werden.According to a preferred development of the invention, the ventilation ducts and / or the ventilation shafts can be closed in areas in which no ventilation is provided. This offers the great advantage that initially a standardized upholstery core is used, in which the corresponding ventilation ducts and / or ventilation shafts are closed during manufacture or subsequently, for example by means of an adhesive or a stopper. In this way, for example, component reduction and thus a cost advantage can be achieved.
Gemäß einer besonders bevorzugten Ausführung ist der Fahrzeugsitz als passiv belüfteter Fahrzeugsitz ausgebildet. Bei passiv belüfteten Fahrzeugsitzen reicht im wesentlichen die bei der Fahrt durch die Bewegung des Fahrzeuginsassen hervorgerufene Pumpwirkung, um eine ausreichende Zirkulation der Luft in den Lüftungskanälen und/oder —schachten zu bewirken. Im Unterschied zu einem aktiv belüfteten Fahrzeugsitz kann somit ein zusätzlicher Lüfter bzw. Ventilator eingespart werden und dadurch eine deutliche Kostensenkung erreicht werden.According to a particularly preferred embodiment, the vehicle seat is designed as a passively ventilated vehicle seat. In the case of passively ventilated vehicle seats, the pumping effect caused by the movement of the vehicle occupant during driving is essentially sufficient to bring about a sufficient circulation of the air in the ventilation ducts and / or shafts. In contrast to an actively ventilated vehicle seat, an additional fan or fan can be saved and a significant cost reduction can be achieved.
Denkbar ist auch, dass der Fahrzeugsitz als aktiv belüfteter Fahrzeugsitz ausgebildet ist, wobei zumindest ein Gebläse o- der ein Miniaturlüfter zur Belüftung des Fahrzeugsitzes vorgesehen ist. Diese Ausführungsvariante gewährleistet eine gegenüber dem passiv belüfteten Fahrzeugsitz deutlich erhöhte Entfeuchtungsleistung, so dass insbesondere in den Sommermonaten durch eine aktive Sitzbelüftung eine zusätzliche Komfortsteigerung erreicht werden kann. Denkbar ist hierbei auch, dass bei Abschalten des Gebläses bzw. des Miniaturlüf- ters der bis dato aktiv belüftete Fahrzeugsitz passiv belüftet wird.It is also conceivable that the vehicle seat is designed as an actively ventilated vehicle seat, at least one blower or a miniature fan being provided for ventilating the vehicle seat. This embodiment variant ensures a significantly increased dehumidification performance compared to the passively ventilated vehicle seat, so that an additional increase in comfort can be achieved in particular in the summer months by active seat ventilation. It is also conceivable that when the blower or miniature fan is switched off The vehicle seat, which has been actively ventilated to date, is passively ventilated.

Fig. 1 eine Draufsicht auf einen erfindungsgemäßen Fahrzeugsitz,1 is a plan view of a vehicle seat according to the invention,
Fig. 2 eine schematische Darstellung einer Körperdruckverteilung eines Standardfahrzeuginsassen auf einem Fahrzeugsitz,2 shows a schematic illustration of a body pressure distribution of a standard vehicle occupant on a vehicle seat,
Fig. 3 eine Darstellung wie in Fig. 1, jedoch mit anders angeordneten Lüftungskanälen.Fig. 3 is an illustration as in Fig. 1, but with differently arranged ventilation channels.
Entsprechend Fig. 1 ist ein Teil eines Fahrzeugsitzes 1, nämlich eine Sitzfläche 2 gezeigt, welche eine Vielzahl von sich kreuzenden Lüftungskanälen 3 aufweist. Sowohl in Fig. 1 als auch in Fig. 2 ist dabei lediglich die Sitzfläche 2 des Fahrzeugsitzes 1 dargestellt, wobei die nachstehend beschriebenen Ausführungen selbstverständlich auch auf eine Lehnenfläche des Fahrzeugsitzes 1 übertragbar sind.According to FIG. 1, part of a vehicle seat 1, namely a seat surface 2, is shown, which has a multiplicity of intersecting ventilation ducts 3. Both in FIG. 1 and in FIG. 2, only the seat surface 2 of the vehicle seat 1 is shown, the ones described below Versions are of course also transferable to a back surface of the vehicle seat 1.
Die Lüftungskanäle 3 sind sowohl in Sitzlängsrichtung als auch in Sitzquerrichtung angeordnet und kreuzen sich in Kreuzungspunkten 9, an welchen jeweils ein quer zu den Lüftungskanälen 3 angeordneter Lüftungsschacht 5 mündet. Die Lüftungskanäle 3 verlaufen entlang und innenseitig einer Sitzfläche 2 bzw. einer nicht dargestellten Lehnenfläche innerhalb des Polsterkerns 4 und sind jeweils im wesentlichen querschnittskonstant ausgebildet. Ebenfalls jeweils querschnittskonstant sind die Lüftungsschächte 5 ausgebildet, welche den Polsterkern 4 in dessen gesamter Dicke durchdringen und sich von den Lüftungskanälen 3 einerseits bis an eine nicht dargestellte und der Sitzfläche 2 abgekehrte Rückwand andererseits erstrecken.The ventilation ducts 3 are arranged both in the longitudinal direction of the seat and in the transverse direction of the seat and intersect at intersection points 9, at each of which a ventilation duct 5 arranged transversely to the ventilation ducts 3 opens. The ventilation ducts 3 run along and on the inside of a seat surface 2 or a back surface (not shown) within the cushion core 4 and are each designed to be essentially constant in cross section. The ventilation shafts 5, which penetrate the cushion core 4 in its entire thickness and extend from the ventilation channels 3 on the one hand to a rear wall, not shown and facing away from the seat surface 2, on the other hand, are likewise formed with a constant cross section.
Gemäß den Fig. 1 und 3 sind dabei die Lüftungskanäle 3 sowie die Lüftungsschächte 5 regelmäßig, das heißt im wesentlichen symmetrisch zu einer mittigen Vertikalebene des Fahrzeugsitzes 1 angeordnet. Eine durchgezogene Linie bedeutet hierbei einen Lüftungskanal 3 bzw. einen Lüftungsschacht 5, welcher zur Belüftung des Fahrzeugsitzes 1 durchströmt wird, wogegen gestrichelte, das heißt mit unterbrochener Linie gezeichnete, Lüftungskanäle 3 bzw. Lüftungsschachte 5 entweder nicht vorgesehen sind oder aber verschlossen sind.1 and 3, the ventilation ducts 3 and the ventilation shafts 5 are arranged regularly, that is to say essentially symmetrically to a central vertical plane of the vehicle seat 1. A solid line here means a ventilation duct 3 or a ventilation shaft 5, which is flowed through for ventilation of the vehicle seat 1, whereas dashed lines, that is to say ventilation lines 3 or ventilation shafts 5 drawn with a broken line, are either not provided or are closed.
Erfindungsgemäß ist vorgesehen, dass eine bestimmte Anordnung, das heißt beispielsweise eine Lage, eine Dichte (Anzahl pro Flächeneinheit) und/oder ein Querschnitt, der Lüftungskanäle 3 und/oder -schachte 5 unterschiedlich stark belüftete Bereiche 6 im Polsterkern 4 definiert, welche an einen Lüftungsbedarf eines nicht dargestellten Standardfahrzeuginsassen angepasst sind. Näher betrachtet bedeutet dies, dass eine Stärke der Belüftung des Fahrzeugsitzes 1 an standardisierte Anatomiedaten des menschlichen Körpers angepasst sind. Eine derartige Anpassung des Lüftungsbedarfs kann beispielsweise anhand einer Körperdruckverteilung 7 (vergleiche Fig. 2) vorgenommen werden. Eine derartige Körperdruckverteilung trennt Sitzbereiche 6 , in welchen eine Belüftung erforderlich ist, und Sitzbereiche 6 , in welchen keine oder nur eine geringe Belüftung erforderlich ist. Darüber hinaus ist selbstverständlich eine weitere Verfeinerung der Bereiche 6 X in unterschiedlich stark belüftete, nicht dargestellte weitere Bereiche möglich. Eine weitere Unterteilung in verfeinerte Bereiche kann beispielsweise anhand einer durch die Körperdruckverteilung 7 generierten Farbkarte bzw. Graustufenkarte gemäß Fig. 2 erfolgen.According to the invention, it is provided that a specific arrangement, that is to say, for example, a position, a density (number per unit area) and / or a cross section, defines the ventilation channels 3 and / or shafts 5 areas 6 in the upholstery core 4 which are ventilated to different extents and which adhere to one Ventilation requirements of a standard vehicle occupant, not shown, are adapted. On closer inspection, this means that a strength of the ventilation of the vehicle seat 1 is adapted to standardized anatomical data of the human body. Such an adjustment of the ventilation requirement can, for example on the basis of a body pressure distribution 7 (see FIG. 2). Such a body pressure distribution separates seat areas 6, in which ventilation is required, and seat areas 6, in which no or only little ventilation is required. In addition, of course, a further refinement of the areas 6 X in different areas with different degrees of ventilation, not shown, is possible. A further division into refined areas can take place, for example, on the basis of a color map or grayscale map according to FIG. 2 generated by the body pressure distribution 7.
Im Bereich 6,λ, in welchem keine Belüftung erforderlich ist, sind gemäß Fig. 1 und Fig. 3 die Lüftungskanäle 3 bzw. die Lüftungsschächte 5 nicht angeordnet bzw. verschlossen.In the area 6 , λ , in which no ventilation is required, the ventilation ducts 3 and the ventilation shafts 5 are not arranged or closed, as shown in FIGS. 1 and 3.
In Bereichen 6λ, in welchen eine deutlich stärkere Belüftung zur Abführung von Schwitzfeuchte erforderlich ist, können die Lüftungskanäle 3 bzw. die Lüftungsschächte 5 beispielsweise einen größeren Querschnitt und/oder eine dichtere Anordnung aufweisen. In Bereichen 6λ, in welchen eine geringere Belüftung erforderlich ist, können die I_.üftungskanäle 3 bzw. die Lüftungsschächte 4 dagegen einen kleineren Querschnitt bzw. eine weiter voneinander entfernte Lage aufweisen.In areas 6 λ , in which a significantly stronger ventilation is required to dissipate perspiration moisture, the ventilation ducts 3 or the ventilation shafts 5 can have, for example, a larger cross section and / or a denser arrangement. In contrast, in areas 6 λ in which less ventilation is required, the ventilation ducts 3 or the ventilation shafts 4 can have a smaller cross-section or a more distant position.
Die Sitzdruckverteilung 7 gemäß Fig . 2 entspricht beispielsweise einer Durchschnittssitzdruckverteilung (z. B. 95%- Perzentil) und wird dadurch einer großen Mehrzahl der Fahrzeuginsassen anatomisch gerecht. Die Anpassung des Querschnitts der Lüftungsschächte 5 bzw. der Lüftungskanäle 3 sowie die Dichte der Lage derselben kann dabei proportional zu einer Farbskala der Sitzdruckverteilung 7 erfolgen.The seat pressure distribution 7 according to FIG. 2 corresponds, for example, to an average seat pressure distribution (e.g. 95% percentile) and thus anatomically does justice to a large majority of vehicle occupants. The adaptation of the cross section of the ventilation shafts 5 or the ventilation ducts 3 and the density of the position thereof can be done in proportion to a color scale of the seat pressure distribution 7.
Darüber hinaus ist denkbar, dass der Fahrzeugsitz 1 als passiv belüfteter Fahrzeugsitz 1 ausgebildet ist, bei welchem eine Belüftung des Polsterkerns 4 lediglich durch konvektive Strömung bzw. durch eine Bewegung des Fahrzeuginsassens auf den Fahrzeugsitz 1 während der Fahrt hervorgerufen wird. Demgegenüber ist aber auch eine Ausbildung des Fahrzeugsitzes 1 als aktiv belüfteter Fahrzeugsitz 1 denkbar, wobei hierbei zumindest ein nicht dargestelltes Gebläse oder ein ebenfalls nicht dargestellter Miniaturlüfter vorgesehen ist. Eine Ausbildung als aktiv belüfteter Fahrzeugsitz 1 bietet den Vorteil, eine erhöhte Entfeuchtungsleistung zu gewährleisten und dadurch auch erhöhte Mengen an angefallener Schwitzfeuchte sicher abführen zu können. Denkbar ist auch eine Kombination aus aktiv und passiv belüftetem Fahrzeugsitz 1, wobei nach dem Abschalten des Gebläses der aktiv belüftete Fahrzeugsitz 1 automatisch in einen passiv belüfteten Fahrzeugsitz 1 überführt wird und umgekehrt .In addition, it is conceivable that the vehicle seat 1 is designed as a passively ventilated vehicle seat 1, in which the upholstery core 4 is ventilated only by convective flow or by movement of the vehicle occupant the vehicle seat 1 is caused while driving. In contrast, it is also conceivable to design the vehicle seat 1 as an actively ventilated vehicle seat 1, in which case at least one blower (not shown) or a miniature fan (also not shown) is provided. Training as an actively ventilated vehicle seat 1 offers the advantage of ensuring an increased dehumidification performance and, as a result, of being able to safely dissipate increased amounts of perspiration moisture. A combination of actively and passively ventilated vehicle seat 1 is also conceivable, wherein after the blower is switched off, the actively ventilated vehicle seat 1 is automatically converted into a passively ventilated vehicle seat 1 and vice versa.
Entsprechend Fig. 1 und Fig. 3 verlaufen die Lüftungskanäle 3 bzw. die Lüftungsschächte 5 im wesentlichen regelmäßig, wobei zusätzlich oder alternativ auch unsymmetrische bzw. unregelmäßig angeordnete Lüftungskanäle 3 bzw. Lüftungsschächte 5 denkbar sind.According to FIG. 1 and FIG. 3, the ventilation ducts 3 and the ventilation ducts 5 run essentially regularly, wherein additionally or alternatively asymmetrical or irregularly arranged ventilation ducts 3 or ventilation ducts 5 are also conceivable.
Zusammenfassend lassen sich die wesentlichen Merkmale der erfindungsgemäßen Lösung wie folgt charakterisieren:In summary, the essential features of the solution according to the invention can be characterized as follows:
Die Erfindung sieht vor, bei einem Fahrzeugsitz 1 mit einem Polsterkern 4, in welchem jeweils querschnittskonstante Lüftungskanäle 3 und Lüftungsschächte 5 verlaufen, durch eine vorbestimmte Anordnung der Lü tungskanäle 3 und/oder der Lüftungsschächte 5 unterschiedlich stark belüftete Bereiche 6 zu definieren. Die derart definierten Bereiche 6 sind dabei an einen Lüftungsbedarf eines Standardfahrzeuginsassen, beispielsweise anhand einer Körperdruckverteilung 7 oder anhand von Körperkontaktstellen, angepasst.The invention provides for a vehicle seat 1 with an upholstery core 4, in which ventilation channels 3 and ventilation shafts 5 each have a constant cross-section, to define ventilation channels 3 and / or ventilation shafts 5 with different levels of ventilation 6 by a predetermined arrangement of the ventilation channels. The areas 6 defined in this way are adapted to a ventilation requirement of a standard vehicle occupant, for example using a body pressure distribution 7 or using body contact points.
Die Lüftungskanäle 3 verlaufen entlang und innenseitig des Polsterkerns 4 bzw. einer Sitzfläche 2 und/oder einer Lehnenfläche, wobei im wesentlichen quer dazu die jeweils quer- schnittskonstanten Lüftungsschächte 5 angeordnet sind, die den Polsterkern 4 in dessen gesamter Dicke durchdringen.The ventilation ducts 3 run along and on the inside of the upholstery core 4 or a seat surface 2 and / or a back surface. Constant ventilation shafts 5 are arranged, which penetrate the cushion core 4 in its entire thickness.
Durch die erfindungsgemäße Lösung wird eine bedarfsgerechte Belüftung einzelner Bereiche 6, 6λ, 6X der Sitzfläche 2 bzw. der Lehnenfläche des Fahrzeugsitzes 1 erreicht und dadurch eine Belüftungsleistung an die jeweiligen Erfordernisse, beispielsweise ein Schwitzfeuchteaufkommen, angepasst. Hierdurch ist es möglich, die entstehende Schwitzfeuchte sicher abzuführen und dadurch dem Fahrzeuginsassen ein komfortables Sitzgefühl zu vermitteln. The solution according to the invention achieves a need-based ventilation of individual areas 6, 6 λ , 6 X of the seat surface 2 or the back surface of the vehicle seat 1, thereby adapting a ventilation performance to the respective requirements, for example the occurrence of sweat moisture. This makes it possible to safely dissipate the resulting sweat moisture and thereby give the vehicle occupant a comfortable seating feeling.
