Abstract

The invention relates to a cushion with a cushion core, particularly made of a foam material, and with an air- and moisture-permeable covering layer that encloses said core. The aim of the invention is to improve the climate comfort by effecting a good removal of moisture from the intermediate area between the covering layer and the cushion core. To this end, interspaced longitudinal and transversal grooves are shaped into the surface of the cushion core that is covered by the covering layer. These grooves are open up to the covering layer and intersect one another. In addition, the cushion core is provided with channels that pass through the entire thickness of the core. Said channels lead to the points of intersection of the longitudinal and transversal grooves as well as to the exterior of the cushion core.

DaimlerChrysler AGDaimlerChrysler AG

Polster für einen FahrzeugsitzUpholstery for a vehicle seat

Die Erfindung betrifft ein Polster für einen Fahrzeugsitz gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a cushion for a vehicle seat according to the preamble of claim 1.

Bei einem bekannten Polster dieser Art (DE 33 06 871 AI) sind in im Sitz- und/oder Lehnenbereich des Polsterkerns angeordneten Längsnuten Halbschalen eingelegt, die zur Außenseite hin offen sind und an einer Seite über einen Hauptverbindungsschlauch mit einer Saugpumpe verbunden sind. Bei einer alternativen Ausführung dieses bekannten Fahrzeugsitzes sind in dem Polsterkern diesen in dessen gesamten Kerndicke durchdringende Kanäle vorgesehen. Die Kanäle sind beidseitig offen und münden an der Unterseite des Polsters frei, indem sie dort durch eine das Polster aufnehmenden Sitzschale des Fahrzeugsitzes hindurchtreten. Mit beiden konstruktiven Gestaltungen des Polsters wird eine Luftabsaugung oder ein Luftaustausch bewirkt, um Wärme und Feuchtigkeit, die sich bei Belegung des Sitzes mit einem Fahrgast zwischen der Deckschicht und dem Polster bildet, abzuführen und dadurch das Sitzklima des Fahrzeugsitzes zu verbessern.In a known upholstery of this type (DE 33 06 871 AI), half-shells are inserted in the longitudinal grooves arranged in the seat and / or backrest area of the upholstery core, which are open to the outside and are connected on one side to a suction pump via a main connecting hose. In an alternative embodiment of this known vehicle seat, channels are provided in the upholstery core which penetrate the entire core thickness thereof. The channels are open on both sides and open out on the underside of the upholstery by passing through a seat shell of the vehicle seat that receives the upholstery. With both structural designs of the upholstery, an air extraction or an air exchange is effected in order to dissipate heat and moisture which is formed between the cover layer and the upholstery when the seat is occupied by a passenger and thereby improve the seat climate of the vehicle seat.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Polster für einen Fahrzeugsitz der eingangs genannten Art, einem sog. Vollschaumpolster, das Sitzklima mit geringem zusätzlichen Fertigungsaufwand weiter zu verbessern.The object of the invention is to further improve the seat climate with little additional manufacturing effort in the case of a cushion for a vehicle seat of the type mentioned at the beginning, a so-called full foam cushion.

Die Aufgabe ist erfindungsgemäß durch die Merkmal des Patentanspruchs 1 gelöst .The object is achieved by the feature of claim 1.

Das erfindungsgemäße Polster für einen Fahrzeugsitz, das sowohl ein Polster für das Sitzteil des Fahrzeugsitzes (Sitzpolster) als auch ein Polster für die Rückenlehne (Lehnen- polster) sein kann, hat den Vorteil, daß durch das Netzwerk aus Längs- und Quernuten, das über die durch den Polsterkern hindurchgehenden Kanäle mit der Raumumgebung in Verbindung steht, ein sehr guter Feuchteabtransport von der Oberfläche des aus feuchteundurchlässigem Material bestehende Polsterkerns bewirkt wird. Über die Längs- und Quernuten erfolgt der Transport der durch die Deckschicht hindurchtretenden Feuchtigkeit zu den Mündungen der Kanäle • und über die Kanäle gelangt die Sehwitzfeuchte ins Freie. Mit dieser passiven Sitzentfeuchtung wird ohne zusätzliche Maßnahmen und Einrichtungen ein ähnlich guter Wirkungsgrad • erzielt , der bei' dem bekannten Polster nur mittels aktiver Luftabsaugung erreichbar ist . Insgesamt wird bei einem kostengünstigen und bauhöhen- kleinen Vollschaumsitz eine sehr gute Luftdurchlässigkeit und Feuchtigkeitsaufnahmefähigkeit des Polsters erreicht, ohne auf teueres Abstandsgewirk wie bei Fahrzeugsitzen der höheren Preisklasse zurückgreifen zu müssen.The cushion according to the invention for a vehicle seat, which has both a cushion for the seat part of the vehicle seat (seat cushion) and a cushion for the backrest (backrest cushion) has the advantage that the network of longitudinal and transverse grooves, which is connected to the room environment via the channels passing through the cushion core, results in very good moisture removal from the surface of the cushion core consisting of moisture-impermeable material. The moisture that passes through the cover layer is transported to the mouths of the channels via the longitudinal and transverse grooves, and the visual moisture is released through the channels. With this passive Sitzentfeuchtung a similarly good efficiency •, is achieved without additional measures and devices which can be reached only by means of active air extraction at 'the known pad. Overall, a very good air permeability and moisture absorption capacity of the upholstery is achieved with a low-cost, low-profile full foam seat without having to resort to expensive spacer fabrics such as vehicle seats in the higher price range.

Vorteilhafte Ausführungsformen des erfindungsgemäßen Polsters mit zweckmäßigen Weiterbildungen und Ausgestaltungen der Erfindung sind in den weiteren Patentansprüchen angegeben.Advantageous embodiments of the cushion according to the invention with expedient further developments and refinements of the invention are specified in the further patent claims.

Gemäß einer vorteilhaften Ausführungsform der Erfindung ist auf der von der Deckschicht abgekehrten Seite des Polsterkerns und mit Abstand von diesem ein Ventilator zum Beaufschlagen eines zentralen Polsterbereichs mit Luft angeordnet. Durch das Vorsehen dieses zentralen Ventilators, der den Polsterkern von außen anbläst, kann der Feuchteabtransport beschleunigt werden und somit auch in Extremsituationen das komfortable Sitzklima aufrechterhalten werden.According to an advantageous embodiment of the invention, on the side of the upholstery core facing away from the cover layer and at a distance therefrom, a fan is arranged to apply air to a central upholstery area. The provision of this central fan, which blows on the upholstery core from the outside, can accelerate the removal of moisture and thus maintain the comfortable seating climate even in extreme situations.

Eine weitere Möglichkeit einer sog. aktiven Entfeuchtung wird gemäß einer vorteilhaften Ausführungs orm der Erfindung dadurch erreicht, daß im Polsterkern mindestens ein diesen in seiner Kerndicke vollständig durchdringender Schacht ausgebildet ist, der zur Polsteraußenseite hin offen ist und in mindestens einer der Längs- und/oder Quernuten mündet. Ein im Schacht angeordneter Miniaturlüfter, der vorzugsweise mittels einer Tülle im Polsterkern positioniert ist, saugt Luft aus der Polsterumgebung an und bläst diese in das Netzwerk aus Längs- und Quernuten ein, wobei die Luft über die im Polster vorhandenen Kanäle wieder abgeführt wird. Diese sehr intensive Luftdurchströmung in den Längs- und Quernuten ermöglicht eine sehr schnelles Abführen von Wärme und Feuchtigkeit aus dem von Deckschicht und Polsterkern begrenzten Polsterzwischenbereich.A further possibility of a so-called. Active dehumidification is achieved according to an advantageous embodiment of the invention in that at least one shaft is completely penetrated in its core thickness in the cushion core, which is open to the outside of the cushion and in at least one of the longitudinal and / or Cross grooves opens. An im A miniature fan arranged in the shaft, which is preferably positioned by means of a grommet in the upholstery core, sucks in air from the upholstery environment and blows it into the network of longitudinal and transverse grooves, the air being discharged again via the channels in the upholstery. This very intensive air flow in the longitudinal and transverse grooves enables heat and moisture to be dissipated very quickly from the intermediate area of the upholstery delimited by the top layer and upholstery core.

Die Erfindung ist anhand von in der Zeichnung dargestellten Ausführungsbeispielen im folgenden näher beschrieben. Es zeigen jeweils in schematischer Darstellung:The invention is described in more detail below with reference to exemplary embodiments shown in the drawing. Each shows in a schematic representation:

Fig. 1 eine Draufsicht eines Sitzpolsters eines Fahrzeugsitzes mit teilweise aufgeschnittener Deckschicht,1 is a plan view of a seat cushion of a vehicle seat with a partially cut cover layer,

Fig. 2 einen Schnitt längs der Linie II - II in Fig. 1,2 shows a section along the line II-II in FIG. 1,

Fig. 3 eine gleiche Darstellung wie in Fig. 1 eines modifizierten Sitzpolsters,3 shows the same representation as in FIG. 1 of a modified seat cushion,

Fig. 4 einen Schnitt längs der Linie IV - IV in Fig. 3.4 shows a section along the line IV-IV in FIG. 3.

Ein Fahrzeugsitz weist in bekannter Weise ein Sitzteil und eine Rückenlehne auf, die beide mit einem Polster belegt sind. In Fig. 1 und 2 ist lediglich das Sitzpolster des Fahrzeugsitzes dargestellt, dessen nachstehend beschriebener Aufbau jedoch in gleicher Weise für das Lehnenpolster gilt.A vehicle seat has a seat part and a backrest in a known manner, both of which are covered with a cushion. 1 and 2 only the seat cushion of the vehicle seat is shown, but the structure described below applies in the same way to the backrest cushion.

Das Polster besteht aus einem als Schaumstoffblock gefertigten Polsterkern 11 und aus einer diesen überziehenden, luft- und feuchtedurchlässigen Deckschicht 12, die ihrerseits eine Auflage 13 aus retikuliertem Schaum und einen luftdurchlässigen Bezug 14 umfaßt, der die Auflage 13 auf der Oberfläche des Polsterkerns 11 festspannt. Der Bezug 14 ist aus Stoff o- der gelochtem Leder. In Einzelfällen kann die Auflage 13 durch ein Faservlies ersetzt werden oder gänzlich entfallen. Üblicherweise ist in die Auflage 13 noch eine Heizmatte für eine Sitzbeheizung eingelegt, die hier nicht dargestellt ist. Das Polster 10 wird im • Sitzteil auf einer Sitzschale oder - wie im beschriebenen Ausführungsbeispiel - auf einem Federkern 15 aufgenommen , der in einem Sitzrahmen des Sitzteils verspannt ist.The pad consists of a pad core 11 made as a foam block and of a covering, air and moisture permeable cover layer 12, which in turn comprises a pad 13 made of reticulated foam and an air permeable cover 14 which clamps the pad 13 on the surface of the pad core 11. The cover 14 is made of fabric or perforated leather. In individual cases the edition 13 can be replaced by a nonwoven or completely eliminated. A heating mat for seat heating, which is not shown here, is usually also inserted in the support 13. The pad 10 is in • the seat part to a seat pan or - which is clamped in a seat frame of the seat part received on a spring core 15 - as in the described embodiment.

Im Polsterkern 11 sind in die der Deckschicht 12 zugekehrte Oberfläche in Längsrichtung verlaufende Längsnuten 16 und in Querrichtung verlaufende Quernuten 17 eingebracht. Längs- und Quernuten 16, 17 kreuzen sich und sind zur Deckschicht 12 hin offen. In den Kreuzungspunkten von Längsnuten 16 und Quernuten 17 münden im Polsterkern 11 Kanäle 18, die den Polsterkern 11 in der gesamten Kerndicke durchziehen und auf der von der Deckschicht 12 abgekehrten Außenseite des Polsterkerns 11 frei münden. Die Längsnuten 16, die Quernuten 17 und die Kanäle 18 werden beim Schäumen des Polsterkerns 11 mit eingeformt .In the upholstery core 11, longitudinal grooves 16 running in the longitudinal direction and transverse grooves 17 running in the transverse direction are introduced into the surface facing the cover layer 12. Longitudinal and transverse grooves 16, 17 intersect and are open to the cover layer 12. At the intersection of longitudinal grooves 16 and transverse grooves 17, channels 18 open in the cushion core 11, which run through the cushion core 11 in the entire core thickness and open freely on the outside of the cushion core 11 facing away from the cover layer 12. The longitudinal grooves 16, the transverse grooves 17 and the channels 18 are also molded in when the cushion core 11 is foamed.

Das Netzwerk aus Längsnuten 16 und Quernuten 17 sorgt in Verbindung mit den Kanälen 18 für einen Feuchtetransport der von einem vom Sitzenden produzierte Schwitzfeuchte von der Deckschicht 12 zur Außenseite des Polsters 10. Über die Längsund Quernuten 16, 17 erfolgt dabei der Feuchtetransport zu den Senken, in denen die Mündungen der Kanäle 18 liegen, und über die Kanäle 18 gelangt die Feuchte ins Freie. Auf diese Weise wird bei dem sog. Vollschaumpolster, dessen Polsterkern selbst nicht feuchtedurchlässig ist, ein komfortables Sitzklima erzeugt, wie dies bei hochwertigen Sitzen nur mit teuerem Abstandsgewirk über dem Polsterkern 11 erreicht wird.The network of longitudinal grooves 16 and transverse grooves 17, in conjunction with the channels 18, ensures moisture transport of the sweat moisture produced by the seated person from the cover layer 12 to the outside of the cushion 10. The longitudinal and transverse grooves 16, 17 are used to transport moisture to the sinks, in which the mouths of the channels 18 are located, and the moisture passes through the channels 18 into the open. In this way, in the case of the so-called full foam cushion, the cushion core of which is not itself permeable to moisture, a comfortable seating climate is generated, as can only be achieved with high-quality seats with an expensive spacer fabric over the cushion core 11.

Wie in Fig. 2 illustriert ist, kann zusätzlich außerhalb des Polsters (beim Sitzpolster unterhalb) mit Abstand von diesem am Fahrzeugsitz ein Ventilator 20 angeordnet sein, der einen zentralen Bereich des Polsterkerns 11 mit Luft beaufschlagt. Durch diesen zentralen Ventilator 20 wird Luft aus der Pols- terumgebung in die im mittleren Bereich des Polsterkerns 11 liegenden Kanäle 18 eingeblasen. Diese Luft gelangt in das Netzwerk aus Längsnuten 16 und Quernuten 17 und strömt über die im Randbereich des Polsterkerns 11 vorhandenen Kanäle 18 wieder zur Polsteraußenseite ab. Die Luftströmung ist in Fig. 2 durch Pfeile angedeutet. Durch diese nunmehr aktive Entfeuchtung des Polsters wird die Wirksamkeit des Abtransports der Schwitzfeuchte, die über die gut luft- und feuchtedurchlässige Deckschicht 12 in die Längs- und Quernuten 16, 17 gelangt, wesentlich gesteigert.As illustrated in FIG. 2, a ventilator 20 can also be arranged outside the upholstery (at the seat upholstery below) at a distance from the upholstery on the vehicle seat, which air is applied to a central area of the upholstery core 11. This central fan 20 removes air from the pole blown into the channels 18 located in the central region of the cushion core 11. This air enters the network of longitudinal grooves 16 and transverse grooves 17 and flows out again via the channels 18 present in the edge region of the cushion core 11 to the outside of the cushion. The air flow is indicated by arrows in FIG. 2. Through this now active dehumidification of the cushion, the effectiveness of the removal of the perspiration moisture, which reaches the longitudinal and transverse grooves 16, 17 via the air and moisture-permeable cover layer 12, is significantly increased.

In dem in Fig. 3 und 4 dargestellten Polster für einen Fahrzeugsitz ist eine alternative Ausführungsform für eine aktive Entfeuchtung des Vollschaumpolsters dargestellt. Der Aufbau des Polsters mit Polsterkern 11 und Deckschicht 12 sowie den in den Polsterkern 11 eingebrachten Längsnuten 16, Quernuten 17 und Kanälen 18 ist unverändert und wie vorstehend zu Fig. 1 und 2 beschrieben. Zusätzlich sind in dem Polsterkern 11 noch zwei mittig im Abstand voneinander angeordnete Schächte 21 vorhanden, die ebenso wie die Kanäle 18 den Polsterkern 11 in der gesamten Kerndicke durchdringen und einerseits im Kreuzungspunkt einer Längsnut 16 und einer Quernut 17 und andererseits frei an der Außenseite des Polsterkerns 11 münden, jedoch gegenüber den Kanälen 18 einen wesentlich größeren lichten Durchmesser aufweisen. Beide Schächte 21 sind im beschriebenen Ausführungsbeispiel in der Mittenachse des Polsterkerns 11 angeordnet, wobei der eine Schacht 21 etwa zentral im Polsterkern 11 liegt, während der andere Schacht 21 näher zur Vorderkante des Polsterkerns 11 hin verschoben ist. In jedem Schacht 21 ist ein Miniaturlüfter 22 angeordnet, der in bekannter Weise über eine hier nicht dargestellte Tülle im Polsterkern 11 festgelegt ist. Mittels der beiden Miniaturlüfter 22 wird Luft von der Außenseite des Polsters angesaugt und über die Schächte 21 in das Netzwerk aus Längsnuten 16 und Quernuten 17 gedrückt. Dort nimmt die Luft die Feuchte auf und strömt über die Kanäle 18 wieder an der Außenseite des Polsterkerns 11 aus. An alternative embodiment for active dehumidification of the full foam cushion is shown in the cushion for a vehicle seat shown in FIGS. 3 and 4. The structure of the upholstery with upholstery core 11 and cover layer 12 and the longitudinal grooves 16, transverse grooves 17 and channels 18 introduced into the upholstery core 11 is unchanged and as described above for FIGS. 1 and 2. In addition, in the upholstery core 11 there are still two shafts 21 arranged at a distance from one another, which, like the channels 18, penetrate the upholstery core 11 in their entire core thickness and on the one hand at the crossing point of a longitudinal groove 16 and a transverse groove 17 and on the other hand freely on the outside of the upholstery core 11 open, but have a much larger clear diameter compared to the channels 18. In the exemplary embodiment described, both shafts 21 are arranged in the center axis of the cushion core 11, one shaft 21 being located approximately centrally in the cushion core 11, while the other shaft 21 is displaced closer to the front edge of the cushion core 11. A miniature fan 22 is arranged in each shaft 21 and is fixed in a known manner via a spout (not shown here) in the cushion core 11. Air is sucked in from the outside of the cushion by means of the two miniature fans 22 and pressed into the network of longitudinal grooves 16 and transverse grooves 17 via the shafts 21. There, the air absorbs the moisture and flows out again via the channels 18 on the outside of the cushion core 11.
