Description

Die Erfindung betrifft ein Lagerelement für Sitz- oder Liegeflächen mit Fußteil und Auflageteller sowie einem Federkörper zwischen beiden, wobei mehrere derartiger Lagerelemente mit ihren Fußteilen insbesondere in Reihen und Spalten auf einer Unterlage angeordnet und auf dieser abgestützt sind und mit ihren Auflagetellern mindestens einen Teil der Sitz- oder Liegefläche überdeckend eine Auflagefläche für eine Polsterauflage, beispielsweise für eine Matratze, bilden. und wobei die Auflageteller (4) derart ausgebildet sind, dass bei Belastung die Polsterauflage (2) auf den Auflagetellern (4) aufliegt und bei Entlastung über deren Auflagefläche (6: 25.1) angehoben ist Aus dem Stand der Technik sind derartige Lagerelemente bekannt, die über Auflageteller verfügen mit einer im wesentlichen runden, ovalen oder quadratischen Auflagefläche, auf die eine Polsterauflage aufgelegt wird. Dabei versteht es sich von selbst, dass eine Vielzahl derartiger Lagerelemente auf einem Lattenrahmen eines Bettgestellrahmens angeordnet, eine federnde Auflagefläche für eine Matratze ergibt, die entsprechend der sich ergebenden Belastungen nachgibt. Dabei ist dieses Nachgeben durch die in Einzelelemente aufgelöste Auflagefläche entsprechend der sich ergebenden Belastungen so verteilt, dass sich eine physiologisch günstige Liegehaltung ergibt. Gleiches gilt auch für andere Polsterflächen, etwa für Sitzflächen, wobei die Lagerelemente auch auf plattigen Unterlagen angeordnet sein können. Als nachteilig wird hierbei angesehen, dass sich bei der auf den einzelnen Auflageflächen der Auflageteller liegenden Matratze in stark beanspruchten Druckbereichen des Liege- bzw. Sitzfeldes, bedingt durch die anliegenden Auflageteller, Eindrücke bilden, in denen diese auch bei entlasteter Matratze an deren Rückseite anliegen, so dass trotz in den Auflagetellern vorgesehenen Öffnungen die gewünschte Hinterlüftung der Matratze und somit auch eine Abfuhr anfallender Feuchtigkeit nur äußert eingeschränkt möglich ist. Bei Lattenrosten treten ähnliche Probleme auf; zu deren Lösung wurden die Latten nach DE 37 08 594 A1 mit strangförmigen Zwischenfederelementen versehen, um so ein Abheben bei Entlastung zur Verbesserung der Hinterlüftung zu erreichen. Diese Ausbildung ist jedoch auf Lattentroste beschränkt. Derartige Lagerkörper für aufgelegte Matratzen beschreiben die WO 99 03379 und die DE 297 12 712; zur Verbesserung der Hinterlüftung werden bei diesen Lagerkörpern auch die Matratzen abgehoben, jedoch sind die so ausgebildeten Lagerkörper komplex in ihrer Herstellung.The invention relates to a bearing element for seating or lying surfaces with foot section and support plate and a spring body between the two, wherein several such bearing elements with their foot parts in particular arranged in rows and columns on a base and are supported on this and at least with their support plates covering a part of the seat or lying surface is a support surface for a cushion, for example for a mattress. and wherein the support plate (4) are designed such that at Load the pad (2) rests on the support plates (4) and is raised above the contact surface (6: 25.1) when the load is released Such bearing elements are known from the prior art, which have support plates with an essentially round, oval or square support surface on which a cushion cover is placed becomes. It goes without saying that a large number of such Bearing elements on a slatted frame of a bed frame arranged, gives a resilient support surface for a mattress that yields according to the resulting loads. Here is this Give way through the contact surface that is broken up into individual elements distributed according to the resulting loads so that results in a physiologically favorable lying position. The same applies to other upholstered surfaces, for example for seating surfaces, the bearing elements can also be arranged on flat documents. As a disadvantage it is considered here that there is a difference between the individual contact surfaces the mattress lying in heavily used mattress Pressure areas of the lying or seating area, due to the adjacent ones Support plates, form impressions, in which these even when unloaded Mattress lie against the back, so that despite the Support plates provided openings the desired rear ventilation of the Mattress and thus also a removal of moisture is only expressed is possible to a limited extent. Similar problems occur with slatted frames on; to their solution, the slats according to DE 37 08 594 A1 were stranded Intermediate spring elements provided, so as to lift off when relieved to improve ventilation. This training is however limited to slatted frames. Such bearing body for on-hook Mattresses describe WO 99 03379 and DE 297 12 712; to improve the rear ventilation also with these bearing bodies the mattresses are lifted off, but the bearing bodies are designed in this way complex to manufacture.

Daraus ergibt sich die der Erfindung zugrundeliegende Aufgabe ein gattungsgemäßes Lagerelement für Sitz- oder Liegeflächen derart weiter zu bilden, dass bei ihrer Anordnung in Reihen und Spalten auf einer Unterlage die verbesserte Hinterlüftung der Matratze mit wirtschaftlich herstellbaren und sicher einsetzbaren Lagerelementen erreicht wird.This results in the object on which the invention is based Generic bearing element for seating or lying surfaces like this to form that when arranged in rows and columns on one Underlay the improved ventilation of the mattress with economical manufacturable and safely usable bearing elements achieved becomes.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Hauptanspruchs gelöst; vorteilhafte Weiterbildungen und bevorzugte Ausführungsformen beschreiben die Unteransprüche.This object is achieved by the characterizing features of the main claim solved; advantageous developments and preferred Embodiments describe the subclaims.

Nach der Erfindung ist der Auflageteller des Lagerelements mit mindestens einem Hubelement versehen, das mit zumindest einer Feder zusammenwirkt, und das zumindest einen Stützkörper aufweist, dessen Oberfläche mit der Polsterauflage zusammenwirkt. Vorteilhaft ist das Hubelement als separates Kunststoff-Spitzgussteil in den Auflageteller eingesetzt und erstreckt sich brückenartig über die Auflagefläche des Auflagetellers, der dabei vorteilhaft eine derartige Ausnehmung, Einnehmung oder Ausformung aufweist, so dass bei Belastung die Brücke des Hubelements bündig in der Auflagefläche liegt. Dabei bildet die Brücke den Stützkörper und hebt mit seiner Oberfläche bei Entlastung der Polsterauflage diese über die Auflagefläche des Auflagetellers hinaus. Vorteilhaft weist der Auflageteller im Bereich der Überbrückung eine derartige Ausformung auf, dass die Brücke des Hubelementes bei belasteter Polsterauflage bündig in der Auflagefläche liegt. According to the invention, the support plate of the bearing element is at least provide a lifting element which interacts with at least one spring, and which has at least one support body, the Surface interacts with the upholstery. That is advantageous Lifting element as separate plastic injection molded part in the support plate used and extends like a bridge over the contact surface the support plate, which advantageously has such a recess, Has recess or shape, so that the bridge under load of the lifting element lies flush in the bearing surface. The forms Bridge the support body and its surface lifts when relieved the cushion cover this over the support surface of the support plate out. The support plate advantageously has in the area of the bridging such a shape that the bridge of the lifting element when the upholstery pad is loaded it lies flush in the pad surface.

Bei dieser Ausbildung liegt das belastete Hubelement mit der Oberfläche des Stützkörpers auf oder in dem Auflageteller. Bei Entlastung der Polsterauflage wird das Hubelement infolge des Zusammenwirkens mit der Feder angehoben, so dass sich die Oberfläche des Stützkörpers über die Auflagefläche des Auflagetellers erhebt. Die Feder/-n ist/sind dabei so ausgelegt, dass die Polsterauflage nach Entlastung des Stützkörpers des Hubelements mitgenommen, von der Auflagefläche des Auflagetellers abgehoben wird. Durch dieses selbsttätige Abheben bildet sich bei Entlastung ein Spalt auf der Rückseite der Polsterauflage zwischen deren Unterfläche und den Auflageflächen der Auflageteller aus, in dem zur verbesserten Hinterlüftung nunmehr Luft zirkulieren kann. Dadurch wird beispielsweise erreicht, dass von der Polsterauflage, etwa der Matratze aufgenommene Feuchtigkeit schneller aus deren Kern entweichen kann, wodurch zum einen der Hygiene Rechnung getragen, zum anderen aber auch die Lebensdauer einer Polsterauflage wesentlich verlängert wird.With this design, the loaded lifting element lies with the surface of the support body on or in the support plate. With discharge the cushion becomes the lifting element as a result of the interaction with the spring raised so that the surface of the support body rises above the support surface of the support plate. The spring (s) is / are designed so that the cushion cover after relieving the Support body of the lifting element taken away from the bearing surface of the Support plate is lifted. Through this automatic take off forms there is a gap on the back of the cushion when relieved between their lower surface and the support surfaces of the support plates in which air now circulates for improved rear ventilation can. This ensures, for example, that the Cushions, such as moisture absorbed by the mattress faster can escape from the core, which on the one hand reduces hygiene Taken into account, but also the lifespan of an upholstery pad is significantly extended.

Dabei weist die Oberfläche des Stützkörpers des Hubelements einen Flächeninhalt auf, der wesentlich geringer ist, als der Flächeninhalt der Auflagefläche des Auflagetellers. Diese Ausbildung hat zur Folge, dass die durch diese Oberfläche abgedeckte Rückseitenfläche der Polsterauflage deutlich kleiner ist, als die abgedeckte Fläche der Polsterunterlage, läge diese vollflächig auf den Auflagetellern auf. So wird zum einen die verfügbare Austauschfläche wesentlich vergrößert; zum anderen wird durch dieses Abheben die Spaltweite vergrößert, was die Luftzirkulation vorteilhaft begünstigt.The surface of the support body of the lifting element has one Area that is significantly less than the area the support surface of the support plate. The result of this training is that the back surface of the cushion cover covered by this surface is significantly smaller than the covered area of the cushion pad, would rest on the full surface of the support plates. So on the one hand, the available exchange area is significantly increased; on the other hand, the gap width is increased by this lifting what the air circulation favorably favors.

Bei einer anderen möglichen Ausbildungsform ist in der Auflagefläche des Auflagetellers zumindest eine Einnehmung oder alternativ eine Ausnehmung vorgesehen. Bei Belastung wird so das Hubelement von dieser Einnehmung aufgenommen, oder es legt sich in die Ausnehmung. Somit wird bei dieser Ausbildung erreicht, dass das belastete Hubelement auf bzw. in dem Auflageteller liegt und die Oberfläche seines Stützkörpers im Wesentlichen bündig mit der Auflagefläche des Auflagetellers ist. Das Einwirken auf die entlastete Polsterauflage ermöglicht die Feder. Diese wird in einer Ausbildungsform durch den Federkörper des Lagerelements selbst gebildet.Another possible form of training is in the contact area the support plate at least one recess or alternatively one Recess provided. When loaded, the lifting element is removed from it Ingested, or it lies in the recess. It is thus achieved in this design that the loaded lifting element is on or in the platen and the surface of his Support body essentially flush with the support surface of the support plate is. The action on the relieved upholstery enables the feather. This is in one form of training by the spring body of the bearing element itself.

Zur Festlegung des in die Auflagefläche des Auflagetellers integrierten Hubelementes an dem Lagerelement ist die in dem Auflageteller vorgesehene Einformung bzw. die Ausnehmung mit Rastmitteln zur Verrastung des Hubelements versehen. Dabei ist beispielsweise das Hubelement durch den Auflageteller geführt und sein oberhalb dieses Auflagetellers liegender Stützkörper kann mit seiner Oberfläche in gleicher Weise mit der Polsterauflage zusammenwirken und diese bei Entlastung über die Auflagefläche des Auflagetellers hinaus anheben.To determine the integrated in the support surface of the support plate Lifting element on the bearing element is that in the support plate intended indentation or the recess with locking means for locking of the lifting element. For example, the lifting element passed through the platen and be above this Support plate lying support body can with its surface in cooperate in the same way with the cushion and this Raise the relief beyond the support surface of the support plate.

Bei einer anderen Ausführungsform ist die mit dem Hubelement zusammenwirkende Feder gegen das Lagerelement abgestützt. Hierbei können zwischen dem Lagerelement und dem Hubelement angeordnete Knickarmoder Balgenfedern vorgesehen sein. Bei einer weiteren Ausführungsform ist die mit dem Hubelement zusammenwirkende Feder gegen den Auflageteller abgestützt. Vorteilhaft ist dabei eine Blattfeder vorgesehen, die mit einem Ende gegen den Auflageteller abgestützt ist und deren freies Ende den Stützkörper mit seiner Oberfläche bildet.In another embodiment, the one that interacts with the lifting element Spring supported against the bearing element. Here you can articulated arm or arranged between the bearing element and the lifting element Bellows springs may be provided. In another embodiment is the spring that interacts with the lifting element against the support plate supported. A leaf spring is advantageously provided, which is supported at one end against the support plate and their free end forms the support body with its surface.

Bei einer bevorzugten Ausführungsform ist der Auflageteller mit paarweise angeordneten Hubelementen ausgestattet. Diese werden vorteilhaft spiegelbildlich zur Mitte angeordnet. In diesem Fall ist es vorteilhaft, wenn für die Hubelemente eines Hubelementen-Paares eine Feder vorgesehen ist, deren Mitte gegen den Auflageteller abgestützt ist und deren äußere, paarig ausgebildete Enden mit den Hubelementen zusammenwirkend, diese bei Entlastung so hochdrücken, dass die Oberflächen der beiden Stützkörper oberhalb der Auflagefläche des Auflagetellers liegen. In a preferred embodiment, the platen is in pairs arranged lifting elements equipped. These will be beneficial arranged in mirror image to the middle. In this case it is advantageous if a spring for the lifting elements of a pair of lifting elements is provided, the middle of which is supported against the support plate and the outer, paired ends with the lifting elements interacting, push it up so that the surfaces release of the two support bodies above the support surface of the support plate lie.

Vorteilhaft ist zumindest der Auflageteller als Kunststoff-Spritzgussteil ausgebildet; dies gewährleistet eine wirtschaftliche Fertigung. Zur Erhöhung der Stabilität des Auflagetellers selbst sind die freien Ränder des Auflagetellers als um etwa 90° aufgebogene Ränder ausgebildet; eine weitere Stabilitätserhöhung ist dadurch erreichbar, dass auch die Ränder der vorgesehenen Ausnehmungen diesen Aufbug aufweisen. Für eine rationelle Fertigung ist das Hubelement als Kunststoff-Spritzgussteil ausgebildet.At least the support plate is advantageous as a plastic injection molded part educated; this ensures economical production. To increase the stability of the platen itself are the free edges of the support plate as edges bent up by about 90 ° educated; a further increase in stability can be achieved that the edges of the recesses provided also have this fold. For rational production, the lifting element is a plastic injection molded part educated.

Such according to the prior art Known bearing element is further developed in that the support plate 4 is provided with a lifting element 7, the support body 9 with its surface when the mattress 2 is unloaded over the contact surface 6 of the platen 4 protrudes.

Diese Hubelemente 7 sind in der Darstellung mit seitlichen angeordneten, blattfederartigen Federn 7.1 versehen, die die Hubelemente 7 gegen den Auflageteller 4 abstützen, und die bewirken, dass das Hubelement 7 mit der Oberfläche seines Stützkörpers 9 die Polsterauflage 2 im entlasteten Zustand von der Auflagefläche 6 des Lagerelementes 1 abdrücken, so dass die entlastete Polsterauflage 2 in eine gegenüber der Auflagefläche 6 erhöhte Stellung gebracht wird. So entsteht spaltartiger Belüftungsraum unter der Polsterauflage 2, der eine hinreichende Luft-Zirkulation zwischen den Auflageflächen 6 der Auflageteller 4 und der Unterseite 8 der Polsterauflage 2 ermöglicht.These lifting elements 7 are arranged with lateral, leaf-spring-like springs 7.1, which the lifting elements 7th support against the support plate 4, and which cause the lifting element 7 with the surface of its support body 9 the cushion pad 2 in the relieved state of the bearing surface 6 of the bearing element 1 press off, so that the relieved upholstery pad 2 in one opposite the support surface 6 is brought to an elevated position. This is how it is created gap-like ventilation space under the cushion pad 2, which is sufficient Air circulation between the support surfaces 6 of the support plate 4 and the bottom 8 of the cushion cover 2 allows.

Dabei weist der Stützkörper 9 des Hubelements 7 eine Oberfläche auf, deren Flächeninhalt wesentlich geringer ausgebildet ist als der der Auflagefläche 6 des Auflagetellers 4. Das Hubelement 7 ist dabei in seiner Ausgestaltung brückenartig ausgebildet (Fig. 6) und erstreckt sich über die Auflagefläche 6 des Auflagetellers 4, über die es sich bei Entlastung erhebt.The support body 9 of the lifting element 7 has a surface, whose surface area is significantly less than that of Support surface 6 of the support plate 4. The lifting element 7 is in its design is bridge-like (Fig. 6) and extends itself on the support surface 6 of the support plate 4, about which it is raised at discharge.

In vorteilhafter Weiterbildung insbesondere des Hubelementes 7 ist dieses in der Auflagefläche 6 des Auflagetellers 4 so integriert, dass die Oberfläche seines Stützkörpers 9 bei Belastung in der Auflagefläche 6 liegt. Wie die Figuren 1 und 2 weiter zeigen, ist hierzu im Bereich der Auflagefläche 6 eine Nut 10 eingewölbt, in die das Hubelement 7 greift; dazu verfügt das Hubelement 7 an seinem unteren Ende über Rastelemente 11, die in Öffnungen in der Nut 10 eingreifen.In an advantageous development, in particular the lifting element 7 this is integrated in the support surface 6 of the support plate 4, that the surface of its support body 9 when loaded in the bearing surface 6 lies. As FIGS. 1 and 2 further show, this is in the area of the support surface 6, a groove 10 is arched, in which the Lifting element 7 engages; for this purpose, the lifting element 7 has its lower one End via locking elements 11 which engage in openings in the groove 10.

Die Figur 3 zeigt eine weitere Variante entsprechend den Figuren 1 und 2, wobei das Hubelement 7 hier Z-artig ausgebildet ist, und die auslaufenden Schenkel 12 des Z in Rastschlitze 13 greifen. Eine andere Variante zeigt Figur 4, wobei hier die Feder 7.1 quasi dreieckförmig ausgebildet ist, und eine Seite mit Rastelementen 11 versehen ist, die wiederum in die Auflagefläche 6 des Auflagetellers 4 einrasten. Figur 5 zeigt eine weitere Variante, die sich dadurch auszeichnet, dass das Hubelement im Wesentlichen W-förmig ausgebildet ist, wobei die einzelnen Schenkel des W durch Öffnungen 14 in der Auflagefläche 6 hindurchragen und die Oberfläche des Stützkörpers 9 die Polsterauflage 2 federnd abstützen.FIG. 3 shows a further variant corresponding to FIG. 1 and 2, wherein the lifting element 7 is Z-like here, and the gripping outgoing leg 12 of the Z in locking slots 13. Another Variant shows Figure 4, here the spring 7.1 quasi triangular is formed, and one side provided with locking elements 11 , which in turn snap into the support surface 6 of the support plate 4. FIG. 5 shows a further variant, which is distinguished by that the lifting element is essentially W-shaped, the individual legs of the W through openings 14 in the support surface 6 protrude and the surface of the support body 9 die Support cushion pad 2 resiliently.

Figur 6 zeigt eine weitere Variante, wobei insbesondere das Hubele ment 7 aus der Auflagefläche 6 herausgearbeitet bzw. ausgeformt ist und in Form einer Überwölbung über der Auflagefläche 6 steht. Um einen progressiver Federweg zu gewährleisten sind in der Überwölbung Einformungen 15 vorgesehen, die eine Nachgiebigkeit der Überwölbung ermöglichen. Die Figur 7 zeigt nochmals eine Variante, bei der das Hubelements 7 mit zusätzlicher Feder 7.1 so ausgebildet ist, dass diese mit dem Federkörper 5 des Auflagetellers 4 zusammenwirkt.Figure 6 shows a further variant, in particular the Hubele ment 7 is worked out or formed from the support surface 6 and is in the form of an arch over the bearing surface 6. Around To ensure a progressive suspension travel in the arch Deformations 15 are provided, the resilience of the arch enable. FIG. 7 again shows a variant in which the Lifting element 7 is designed with an additional spring 7.1 such that this cooperates with the spring body 5 of the support plate 4.

Die Figuren 8a und 8b zeigen eine Ausbildung eines Lagerelements 20 für Sitz- oder Liegeflächen mit auf einer (nicht näher dargestellten) Unterlage abstützbarem Federkörper 21, der eine Basisplatte 22 mit einer (hier als Langloch dargestellten) Befestigungsöffnung 22.1 zum Festlegen auf der Unterlage 3 (Fign. 1-7) aufweist (wobei selbstverständlich ist, dass auch jede andere Befestigung der Basisplatte auf der Unterlage möglich ist). Von dieser Basisplatte 22 gehen Federarme 23 aus, deren freie Enden 24 mit dem Auflageteller zusammenwirken, und die über Wellfedern 23.1 mit den Federarmen 23 verbunden sind, um deren Auswärtsbewegung beim Niederdrücken auffangen zu können.FIGS. 8a and 8b show an embodiment of a bearing element 20 for seating or lying areas with on a (not shown) Supportable spring body 21 having a base plate 22 with a (shown here as an elongated hole) opening 22.1 for Fix on the pad 3 (Figs. 1-7) has (although of course is that any other attachment to the base plate the document is possible). Spring arms extend from this base plate 22 23, the free ends 24 of which interact with the support plate, and which are connected to the spring arms 23 via wave springs 23.1 to be able to absorb their outward movement when depressed.

Die freien Enden 24 der Federarme 23 tragen den Auflageteller 25 mit seinen Randbereichen 25.1 und demgegenüber eingenommenen Zentralbereich 25.2. Dazu weisen diese freien Enden 24 Öffnungen auf, die an die Innenseite des Auflagetellers 25 angeformte Verbinder 26 aufnehmen. Um solche Lagerelemente 20 auch so ausbilden zu können, dass (hier nicht dargestellte) Seitenholme des Rahmens übergriffen werden, sind an zwei einander gegenüberliegenden Seiten weitere, nach innen versetzte Verbinder 26' angeordnet, die mit entsprechenden (hierfür nicht besonders dargestellten) Federkörpern so zusammenwirken, dass ein Teil des Auflagetellers 25 entweder rechts oder links überstehend, den Seitenholm übergreift.The free ends 24 of the spring arms 23 support the support plate 25 its marginal areas 25.1 and the central area occupied by it 25.2. For this purpose, these free ends have 24 openings which the inside of the support plate 25 take molded connector 26. In order to be able to design such bearing elements 20 such that side rails of the frame (not shown here) are overlapped, are further on two opposite sides, inside offset connector 26 'arranged with corresponding (for this spring bodies (not particularly shown) interact so that a part of the support plate 25 protruding either on the right or left, engages over the side rail.

Der in seinen Einzelheiten in den Figuren 9a, 9b und 10 besonders herausgestellte Auflageteller 25 ist weiter mit Hinterlüftungsöffnungen 27 und 27.1 versehen. Zwei weitere Öffnungen 28 sind einander gegenüberliegend angeordnet und länglich-schlitzförmig ausgebildet. Unter dem Auflageteller 25 ist das Hubelement 30 angeordnet, dessen Grundplatte bzw. Feder 32 von an der Unterseite des Auflagetellers 25 vorgesehenen seitlichen Winkelleisten 29 mit hakenförmigem Querschnitt gehalten ist. Diese Winkelleisten 29 sind dabei so ausgebildet und wirken so mit der Grundplatte bzw. der Feder 32 des Hubelements 30 zusammen, dass dieses mittels Einklipsen an der Unterseite des Auflagetellers 25 befestigt werden kann. Dazu weist die Grundplatte bzw. die Feder 32 (nicht näher bezeichnete) seitliche Ausnehmungen auf, die von den hakenförmigen Winkelleisten 29 übergriffen werden. Die seitlichen Federarme 32.1 bilden Blattfedern, deren freie Enden mit den Stützkörpern 33 versehen sind, die als paarig angeordnete Hubelemente 30.1 und 30.2 durch länglich-schlitzförmige Öffnungen 28 im Auflageteller 25 hindurchgreifen.The particular in its details in Figures 9a, 9b and 10 exposed support plate 25 is further with rear ventilation openings 27 and 27.1 provided. Two other openings 28 are each other arranged opposite and elongated slit-shaped. Under the support plate 25, the lifting element 30 is arranged, the Base plate or spring 32 from on the underside of the support plate 25 provided side angle strips 29 with a hook-shaped cross section is held. These angle strips 29 are designed in this way and thus act with the base plate or the spring 32 of the lifting element 30 together that this by clipping on the bottom the support plate 25 can be attached. The base plate points to this or the spring 32 (unspecified) lateral recesses on which the hook-shaped angle strips 29 overlap become. The side spring arms 32.1 form leaf springs, their free Ends are provided with the support bodies 33, which are arranged in pairs Lifting elements 30.1 and 30.2 through elongated, slit-shaped openings 28 reach through in the support plate 25.

Bei belasteter Polsterauflage sind die Oberflächen dieser Stützkörper 33 niedergedrückt, wobei die Seitenarme 32.1 der Federn 32 ausgelenkt und somit gespannt sind. Nach Entlastung können sich diese Seitenarme 32.1 der Feder 32 entspannen und die Stützkörper 33 hochdrücken, die ihrerseits mit ihrer Oberfläche die Unterseite der Polsterauflage stützend, diese hierbei anheben und somit zur Verbesserung der Hinterlüftung Sorge tragen.When the upholstery is loaded, the surfaces of these support bodies are 33 depressed, the side arms 32.1 of the springs 32 being deflected and are therefore excited. After relieving these side arms 32.1 of the spring 32 relax and push the support body 33 up in turn, with its surface, the underside of the cushion cover supportive, raise them here and thus improve the rear ventilation Take care.
