Description

Technisches GebietTechnical area

Die Erfindung betrifft ein Lagerelement für eine Polsterautlage von Sitz- und Liegeflächen, vorzugsweise für Matratzen, mit einer an einer Unterlage festlegbaren Bodenplatte, mindestens einem von der Bodenplatte nach oben in Richtung der Polsterauflage hoch stehenden, aus einer Mehrzahl von Federarmen bestehenden Federelement und einer zur Auflage des Polsterelementes vorgesehenen Auflageplatte, welche im Wesentlichen aus einer Mehrzahl von mit den Federarmen des Federelementes an deren oberen Ende verbundenen Auflageflächen besteht.The invention relates to a bearing element for a upholstery of seat and lying surfaces, preferably for mattresses, with a base plate fixed to a base, at least one of the bottom plate up in the direction of the cushion support high, consisting of a plurality of spring arms spring element and a to Pad of the pad member provided support plate, which consists essentially of a plurality of connected to the spring arms of the spring element at the upper end bearing surfaces.

Stand der TechnikState of the art

Lagerelemente der eingangs geschilderten gattungsgemäßen Art sind aus dem Stand der Technik in mannigfaltiger Ausgestaltung hinlänglich bekannt z.B. aus FR 2 790 929 A1 . Aus derartigen Lagerelementen werden so genannte Polsterunterlagen gebildet, die der Auflage eines Polsters, auf dem ein Körper körpergerecht gelagert werden kann, dienen. Die auf der Polsterunterlage aufgelegten Polsterauflagen, wie beispielsweise Matratzen, nehmen bei Benutzung von der auf der Polsterauflage liegenden Person Körperfeuchte auf, die in die Polsterauflage eindringt. Die aufgenommene Feuchtigkeit sollte zum Schutz der Polsterauflage gegen vorzeitige Alterung nach unten in Richtung der durch die Lagerelemente gebildeten Polsterunterlage abgeführt werden.Bearing elements of the generic type described above are well known from the prior art in diverse design eg from FR 2 790 929 A1 , From such storage elements so-called cushion pads are formed, which serve the support of a cushion on which a body can be stored properly. The upholstered pads, such as mattresses, placed on the cushion pad, when used by the person lying on the cushion pad, absorb body moisture which penetrates into the cushion pad. The absorbed moisture should be dissipated to protect the cushion pad against premature aging down in the direction of the cushion pad formed by the bearing elements.

Hierbei besteht die besondere Problematik, dass die Lagerelemente bzw. die am Lagerelement zur Auflage der Polsterauflage vorhandenen Auflageplatten zur Erhöhung des Liegekanforts für eine auf der Polsterauflage liegende Person in aller Regel eine möglichst große Flächenausdehnung haben, um ein gleichmäßiges Einsinken der auf dem Lagerelement befindlichen Matratze durch das Gewicht der auf der Matratze liegenden Person zu ermöglichen, wobei natürlich unterschiedliche Einsinktiefen der Lagerelemente nicht ausgeschlassen sind, die sich aus verschiedenen Gewichtsbelastungen auf die Matratze ergeben. Natürlich sind in den Auflageplatten zur Hinterlüftung der Polsterauflage regelmäßig Durchbrechungen vorgesehen, die jedoch für eine ausreichende Hinterlüftung der Polsterauflage als Voraussetzung zur Ableitung von Körperfeuchtigkeit nicht ausreichen.Here, there is the particular problem that the bearing elements or existing on the bearing element for supporting the pad support plates to increase the Liegekanforts for a person lying on the cushion pad usually have the largest possible surface area to a uniform sinking of the mattress located on the bearing element to allow by the weight of lying on the mattress person, of course, different sinking depths of the bearing elements are not skipped, resulting from different weight loads on the mattress. Of course, perforations are regularly provided in the support plates for ventilation of the cushion cover, but not sufficient for adequate ventilation of the cushion support as a prerequisite for the derivation of body moisture.

Um das Problem einer ausreichenden Hinterlüftung zu lösen, sind aus dem Stand der Technik Lösungen bekannt geworden - beispielsweise aus der EP 1 121880 der Anmelderin - bei der die Auflageplatten mindestens ein als separates Kunststoffspritzgussteil ausgebildetes Hubelement mit einer mit diesem zusammenwirkenden Feder aufweisen, durch die bei entlasteter Polsterauflage diese über die eigentliche durch die Oberseite der Autlageplatten definierte Auflageebene angehoben wird. Die mit dem Hubelement zusammenwirkende Feder ist dabei so ausgebildet, dass sie infolge ihrer Federsteifigkeit Federkräfte bereitstellt, die größer sind als die infolge des Polsterautlagegewichtes auf das Lagerelement wirkenden Gewichtskräfte in unbelastetem Zustand.To solve the problem of adequate ventilation, solutions have become known from the prior art - for example, from EP 1 121880 of the Applicant - in which the support plates have at least one lifting element designed as a separate plastic injection molded part with a spring cooperating therewith, by means of which, when the cushion support is relieved, it is raised above the actual support plane defined by the upper side of the support plates. The cooperating with the lifting element spring is designed so that it provides spring forces due to their spring stiffness, which are greater than the weight of the forces acting on the bearing element due to the upholstery weight in the unloaded state.

Die geschilderte Lösung zur Verbesserung der Hinterlüftung von Polsterauflagen hat sich prinzipiell im Stand der Technik durchaus bewährt. Allerdings ist die Herstellung des aus der geschilderten Lösung bekannten Hubelementes als separates Spritzgussbauteil mit nicht unerheblichen Herstellkosten verbunden, wobei darüber hinaus natürlich auch der zusätzliche Materialeinsatz und die Montagekosten des Zusatzbauteiles zu berücksichtigen sind.The described solution for improving the ventilation of cushions has proven in principle quite well in the prior art. However, the production of the well-known from the described solution lifting element is connected as a separate injection molding with significant manufacturing costs, moreover, of course, the additional use of materials and the installation costs of the additional component are taken into account.

Darstellung der ErfindungPresentation of the invention

Aufgabe der vorliegenden Erfindung ist es daher, ein Lagerelement für eine Polsterauflage von Sitz- und Liegeflächen so weiter zu entwickeln, dass gegenüber den aus dem Stand der Technik bekannten Lösungen eine nochmals verbesserte Hinterlüftung der Polsterauflage erreicht wird und darüber hinaus das Lagerelement wirtschaftlich herstellbar und sicher und dauerhaft einsetzbar ist.Object of the present invention is therefore to develop a bearing element for a cushion pad of seats and reclining surfaces so that compared to the known from the prior art solutions, a further improved ventilation of the cushion support is achieved and beyond the bearing element economically manufacturable and safe and is permanently usable.

Diese Aufgabe wird erfindungsgemäß in Zusammenschau mit den gattungsbildenden Merkmalen des Anspruchs 1 durch die im kennzeichnenden Teil des Anspruches offenbarte technische Lehre gelöst.This object is achieved according to the invention in conjunction with the generic features of claim 1 by the technical teaching disclosed in the characterizing part of the claim.

Erfindungswesentlich dabei ist es, dass die Auflageflächen bei auf das Lagerelement aufgelegter unbelasteter Polsterauflage von der durch die freien oberen Enden der Federarme definierten Auflageebene schräg nach oben in einem spitzen Winkel zur Auflageebene aus dieser hervorstehen.It is essential to the invention that the support surfaces projecting out of the support surface defined by the free upper ends of the spring arms obliquely upwards at an acute angle to the support plane when placed on the bearing element unencumbered cushion pad.

Die schräg nach oben stehenden Auflageflächen bewirken, dass an deren hoch stehenden freien Enden eine punkt- oder linienförmige Auflagezone für die unbelastete Matratze gebildet wird. Die Matratze liegt somit nur an einzelnen Punkten oder Linien ihrer Unterseite auf, so dass die übrige freie Fläche für eine vorteilhafte Hinterlüftung der Polsterauflage dienen kann.The obliquely upstanding bearing surfaces cause a punctiform or linear support zone for the unloaded mattress is formed at the upstanding free ends. The mattress is thus only at individual points or lines on their underside, so that the rest of the free area can be used for an advantageous ventilation of the cushion pad.

Darüber hinaus ist für die erfindungsgemäße Gestaltung des Lagerelementes kein zusätzliches Bauelement notwendig, so dass jegliche Mehrkosten gegenüber aus dem Stand der Technik bekannten üblichen Lagerelementen entfallen. Darüber hinaus ist vorteilhaft, dass für die erfindungsgemäßen Lagerelemente, welche mit keinem speziellen Hubelement wie aus dem Stand der Technik bekannt ausgestattet sind, notwendigen Montagekosten des separaten Bauteils entfallen.In addition, no additional component is necessary for the inventive design of the bearing element, so that any additional costs compared to the The prior art known conventional storage elements account for. Moreover, it is advantageous that account for the mounting elements according to the invention, which are equipped with no special lifting element as known from the prior art, necessary assembly costs of the separate component.

Besondere Ausgestaltungen des Gegenstandes der Erfindung ergeben sich zusätzlich aus den Merkmalen der Unteransprüche.Particular embodiments of the subject matter of the invention additionally result from the features of the subclaims.

Es hat sich insbesondere als vorteilhaft erwiesen, wenn der Winkel der Auflageflächen in unbelasteten Zustand zur Auflageebene im belasteten Zustand der Matratze im Bereich von 5 bis 40 Grad liegt. Bei diesen vorgegebenen Winkelmaßen ist zum einen eine ausreichende Hinterlüftung der Matratze gegeben, andererseits ist die Anhebung der Matratze im unbelasteten Zustand durch die nach oben stehenden Auflageflächen gering genug, damit ein störender optischer Eindruck vermieden wird.It has proven particularly advantageous if the angle of the support surfaces in the unloaded state to the support plane in the loaded state of the mattress is in the range of 5 to 40 degrees. At these predetermined angular dimensions, a sufficient ventilation of the mattress is given on the one hand, on the other hand, the elevation of the mattress in the unloaded state by the upstanding support surfaces is low enough so that a disturbing visual impression is avoided.

Eine weitere vorteilhafte Weiterbildung des Gegenstandes der Erfindung sieht vor, dass die Auflageflächen an einem ringförmigen, die oberen freien Enden der Federarme verbindenden Rahmenelement angeordnet sind. Das Rahmenelement bewirkt ein gleichmäßiges Einfedern der Federarme und stellt ein stabiles Anbindungselement für die Auflageflächen dar.A further advantageous development of the subject matter of the invention provides that the bearing surfaces are arranged on an annular, connecting the upper free ends of the spring arms frame member. The frame element causes a uniform compression of the spring arms and provides a stable connection element for the bearing surfaces.

Es hat sich darüber hinaus als zweckmäßig erwiesen, dass die Auflageflächen im Wesentlichen eine plattenförmige im Grundriss dreieckige Formgebung aufweisen, wobei eine Längsseite des dreieckförmigen Grundrisses an dem ringförmigen Rahmenelement oder dem freien Ende eines Federarmes festgelegt sind. Die geschilderte Gestaltung führt dazu, dass die Auflageflächen an derjenigen Seite, die der Ringfläche abgewandt ist, aufgrund ihrer Grundrissgestaltung einzelne punktförmige Auflagezonen für die Matratze bereitstellen.It has also proven to be expedient that the bearing surfaces essentially have a plate-shaped in plan view triangular shape, wherein a longitudinal side of the triangular plan are fixed to the annular frame member or the free end of a spring arm. The described design causes the bearing surfaces on the side facing away from the annular surface to provide individual punctiform support zones for the mattress due to their layout design.

Diese punktförmigen Auflagezonen sind für die verbesserte Hinterlüftung der aufgelegten Matratzen optimal. Zusätzlich vorteilhaft kann darüber hinaus die Ausgestaltung der Auflageflächen dahingehend sein, dass diese mindestens eine oder vorzugsweise mehrere Durchbrechungen aufweisen. Die Durchbrechungen erhöhen die Hinterlüftungsmöglichkeit im belasteten Zustand der Matratze und unterstützen zusätzlich auch bei Gebrauch der Matratze durch eine darauf liegende Person die Abführung von Körperfeuchtigkeit.These punctiform support zones are optimal for the improved ventilation of the applied mattresses. In addition, the design of the bearing surfaces may additionally be advantageous in that they have at least one or preferably a plurality of apertures. The openings increase the possibility of ventilation in the loaded state of the mattress and additionally support the removal of body moisture even when the mattress is being used by a person lying on it.

Die Anordnung der an dem Rahmenelement oder dem freien Ende der Federarme angeordneten Auflageflächen kann dabei sowohl nur an der Innenseite oder an der Außenseite vorstehend vorgesehen sein. Die jeweilige Anordnung ist von den Platzgegebenheiten abhängig, die für die erfindungsgemäßen Lagerelemente zur Verfügung stehen.The arrangement of the arranged on the frame member or the free end of the spring arms bearing surfaces can be provided protruding both only on the inside or on the outside. The particular arrangement is dependent on the space conditions that for the bearing elements according to the invention for To be available.

Darüber hinaus ist es natürlich denkbar, dass an dem Rahmenelement nach innen und außen vorstehende Auflageflächen angeordnet sind, wobei entweder alle Auflageflächen oder nur die nach innen bzw. nach außen seitlich vorstehend angeordneten Auflageflächen erfindungsgemäß schräg nach oben in einem spitzen Winkel zur Auflageebene aus dieser hervorstehen.In addition, it is of course conceivable that on the frame element inwardly and outwardly projecting bearing surfaces are arranged, wherein either all bearing surfaces or only the inwardly or outwardly laterally projecting bearing surfaces according to the invention project obliquely upward at an acute angle to the support plane of this ,

Bester Weg zur Ausführung der ErfindungBest way to carry out the invention

Das in den Figuren 1 und 2 dargestellte erfindungsgemäße Lagerelement besteht im Wesentlichen aus einer Bodenplatte 1, mit der es an einer geeigneten Unterlage (nicht näher dargestellt) wie beispielsweise einem Lattenrost für ein Bett oder ein Sitzmöbel festgelegt werden kann. Die Festlegung erfolgt dabei durch bekannte Befestigungstechniken, wie beispielsweise Verschraubungen oder so genannte Bajonettverbindungen, wie sie an der Bodenplatte 1 in der Darstellung der Figur 1 verdeutlicht sind. Die Bajonettverbindung dient dabei einer zeitsparenden und problemlos wieder lösbaren Befestigung des gesamten Lagerelementes.That in the FIGS. 1 and 2 illustrated bearing element according to the invention consists essentially of a bottom plate 1, with which it (not shown in detail) can be fixed to a suitable surface such as a slatted frame for a bed or a piece of furniture. The determination is carried out by known fastening techniques, such as glands or so-called bayonet joints, as shown on the bottom plate 1 in the representation of FIG. 1 are clarified. The bayonet connection serves a time-saving and easily releasable attachment of the entire bearing element.

Von der Bodenplatte stehen im dargestellten Ausführungsbeispiel vier Federarme 2a, 2b, 2c, und 2d, die gemeinsam das Federelement 2 bilden, nach oben in Richtung einer in den Figuren nicht näher dargestellten Polsterauflage hoch. Die Federarme sind im Wesentlichen streifenförmig ausgebildet und besitzen an ihren oberen, der Bodenplatte 1 abgewandten Enden eine wellenförmige Zone 9, die einer verbesserten Federwirkung des Lagerelementes dient. Auf die Federarme des Federelementes 2 aufgesetzt und mit diesen einstückig verbunden ist ein ringförmiges Rahmenelement 3. Das Rahmenelement 3 verbindet die einzelnen Federarme 2a, 2b, 2c und 2d miteinander und gewährleistet ein gleichmäßiges Einfedern des Federelementes 2 infolge einer auf die Polsterauflage bzw. die Matratze einwirkenden Gewichtskraft.From the base plate are in the illustrated embodiment, four spring arms 2a, 2b, 2c, and 2d, which together form the spring element 2, upwards in the direction of a cushion pad not shown in the figures. The spring arms are substantially strip-shaped and have at their upper ends facing away from the bottom plate 1 a wave-shaped zone 9, which serves an improved spring action of the bearing element. The frame member 3 connects the individual spring arms 2a, 2b, 2c and 2d with each other and ensures a uniform compression of the spring element 2 as a result of a pad on the mattress or mattress acting weight.

Die Oberseite des Rahmenelementes bildet dabei, wie dies aus der Figur 2 ersichtlich ist, die Auflageebene 7 für die auf dem Lagerelement aufliegende Polsterauflage im belasteten Zustand.The top of the frame element forms, as can be seen from the FIG. 2 it can be seen, the support plane 7 for resting on the bearing element cushion pad in the loaded state.

Aus der Figur 1 ist ersichtlich, dass im vorliegenden Ausführungsbeispiel an dem ringförmigen Rahmenelement 3 an dessen Innenseite seitlich vorstehend vier Auflageflächen 4a, 4b, 4c und 4d angeordnet sind. Diese Auftageflächen besitzen eine im Wesentlichen plattenförmige Gestalt und sind im Grundriss dreieckförmig ausgebildet. Eine Längsseite der Auflageflächen 4a, 4b, 4c und 4d ist dabei an dem Rahmenelement 3 festgelegt. Durch diese konstruktive Gestaltung ergibt sich an der dem Rahmenelement 3 abgewandten Seite eine gerundete Spitze 10 der jeweiligen Auflagerfläche.From the FIG. 1 It can be seen that in the present exemplary embodiment four support surfaces 4a, 4b, 4c and 4d are arranged laterally on the inner side of the annular frame element 3. These support surfaces have a substantially plate-like shape and are triangular in plan. A longitudinal side of the bearing surfaces 4a, 4b, 4c and 4d is fixed to the frame member 3. By this structural design results on the side facing away from the frame member 3 a rounded tip 10 of the respective bearing surface.

Die erfindungsgemäße Gestaltung des Lagerelementes sieht nunmehr vor, dass die genannten Auflageflächen 4a, 4b, 4c und 4d bei auf das Lagerelement aufgelegter, unbelasteter Polsterauflage von der durch das Rahmenelement definierten Auflageebene 7 schräg nach oben in einem spitzen Winkel zur Auflageebene 7 aus dieser hervorstehen. Die besondere Gestaltung der Auflageflächen 4a, 4b, 4c und 4d ist insbesondere der Figur 2 gut zu entnehmen. Es ist somit durch die nach oben stehenden Auflageflächen eine zweite Auflageebene 8, die durch die Spitzen 10 der Auflagefläche 4a, 4b, 4c und 4d in ihrem Höhenniveau oberhalb der Auflageebene 7 definiert ist, gegeben. Die erfindungsgemäße Gestaltung führt im dargestellten Ausführungsbeispiel zu im Wesentlichen punktförmigen Auflagezonen für die aufliegende Polsterauflage oder Matratze, so dass außer den punktförmigen Auflagezonen, die gesamte Unterseite der Matratze hinterlüftet ist und zur Abführung von Körperflüssigkeit dienen kann.The design of the bearing element according to the invention now provides that said bearing surfaces 4a, 4b, 4c and 4d projecting from the support plane defined by the frame element 7 obliquely upwards at an acute angle to the contact plane 7 when the pad rest is laid on the bearing element. The particular design of the bearing surfaces 4a, 4b, 4c and 4d is in particular the FIG. 2 good to take. It is thus by the upstanding support surfaces, a second support level 8, which is defined by the tips 10 of the support surface 4a, 4b, 4c and 4d in their height level above the support level 7 given. The design of the invention leads in the illustrated embodiment to substantially point-shaped support zones for the overlying cushion pad or mattress, so that except the punctiform support zones, the entire bottom of the mattress is ventilated and can serve to dissipate body fluid.

Die Schrägstellung der Auflageebenen 4a, 4b, 4c und 4d liegt, wie dies insbesondere aus der Figur 2 deutlich wird, im dargestellten Ausführungsbeispiel im Bereich von ca. 15 Grad gegenüber der horizontalen Auflageebene 7, wobei auch noch geringere Winkel der Auflageflächen 4a, 4b, 4c und 4d im Bezug zur Auflageebene 7 im Bereich bis zu 5 Grad denkbar sind. Bedarfsweise sind jedoch auch größere Winkel im Bereich bis zu 40 Grad vorsehbar. Der gewählte spitze Winkel zwischen Auflageebene 7und Auflageflächen 4a, 4b, 4c und 4d hängt dabei von der Querschnittgestaltung und der daraus resultierenden Steifigkeit der hoch stehenden Auflageflächen 4a, 4b, 4c und 4d ab, die auf das Gewicht der aufliegenden Matratze konstruktiv abzustimmen ist.The inclination of the support planes 4a, 4b, 4c and 4d is, as in particular from FIG. 2 becomes clear, in the illustrated embodiment in the range of about 15 degrees relative to the horizontal support plane 7, with even lower angles of the support surfaces 4a, 4b, 4c and 4d in relation to the support plane 7 in the range up to 5 degrees are conceivable. If necessary, however, larger angles in the range of up to 40 degrees are foreseeable. The selected acute angle between the support plane 7 and bearing surfaces 4a, 4b, 4c and 4d depends on the cross-sectional design and the resulting rigidity of the upstanding support surfaces 4a, 4b, 4c and 4d, which is to be adapted constructively to the weight of the overlying mattress.

Das in den Figuren 3 und 4 dargestellte weitere Ausgestaltungsbeispiel des erfindungsgemäßen Lagerelementes besitzt hinsichtlich wesentlicher Elemente einen identischen Aufbau wie das Ausführungsbeispiel der Figuren 1 und 2, so dass für die Kennzeichnung übereinstimmender Bauteile eine identische Bezifferung gewählt wurde.That in the Figures 3 and 4 shown further embodiment of the bearing element according to the invention has a view with respect to essential elements identical structure as the embodiment of FIGS. 1 and 2 , so that an identical numbering was chosen for the marking of matching components.

So ist aus den genannten Figuren ersichtlich, dass das erfindungsgemäße Lagerelement eine Bodenplatte 1 aufweist, mit der es an einer geeigneten Unterlage, wie beispielsweise einem Lattenrost für ein Bett oder ein Sitzmöbel festgelegt werden kann. Von der Bodenplatte 1 aus erstrecken sich im dargestellten Ausführungsbeispiel vier Federarme 2a, 2b, 2c, und 2d, die gemeinsam das Federelement 2 bilden, nach oben in Richtung einer in den Figuren 3 und 4 nicht näher dargestellten Polsterauflage hoch. Die Ausgestaltung der Federarme 2a bis 2d entspricht prinzipiell derjenigen Ausgestaltung der Federarme, wie sie bereits in den Figuren 1 und 2 offenbart ist, so dass an dieser Stelle auf nähere Erläuterungen verzichtet wird.Thus, it can be seen from the cited figures that the bearing element according to the invention has a base plate 1, with which it can be fixed to a suitable base, such as a slatted frame for a bed or a piece of furniture. From the base plate 1 extend in the illustrated embodiment, four spring arms 2a, 2b, 2c, and 2d, which together form the spring element 2, upwards in the direction of one in the Figures 3 and 4 not shown cushion pad high. The design of the spring arms 2a to 2d corresponds in principle to that embodiment of the spring arms, as they are already in the FIGS. 1 and 2 is disclosed, so that will be omitted at this point for further explanation.

Am oberen, der Bodenplatte 1 abgewandten freien Ende der jeweiligen Federarme 2a bis 2d befindet sich im Ausführungsbeispiel der Figuren 3 und 4 jeweils eine Auflagefläche 4a, 4b, 4c und 4d. Die Auflageflächen besitzen eine im Wesentlichen viereckige Grundrissgestaltung und sind analog zum Ausführungsbeispiel der Figuren 1 und 2 jeweils mit mehreren Durchbrechungen 5 versehen. Im Gegensatz zum Ausführungsbeispiel der Figuren 1 und 2 sind die einzelnen Auflageflächen 4a bis 4d untereinander nicht mittels eines Rahmenelementes verbunden, so dass sie einzeln einfedern können.At the top, the bottom plate 1 facing away from the free end of the respective spring arms 2a to 2d is located in the embodiment of Figures 3 and 4 each a support surface 4a, 4b, 4c and 4d. The bearing surfaces have a substantially quadrangular layout and are analogous to the embodiment of FIGS. 1 and 2 each provided with a plurality of openings 5. In contrast to the embodiment of FIGS. 1 and 2 the individual bearing surfaces 4a to 4d are not connected to each other by means of a frame element, so that they can deflect individually.

Wie der Seitenansicht der Figur 4 zu entnehmen ist, stehen die Auflageflächen 4a, 4b, 4c und 4d ausgehend von dem freien Ende der Federarme 2a bis 2d, die die Auflageebene 7 bei unter Last aufliegender Polsterauflage oder Matratze definieren, schräg nach oben in einem spitzen Winkel aus der Auflageebene heraus, so dass die den Federelementen 2a bis 2d gegenüber liegenden Eckbereiche der Auflageflächen eine oberhalb der Auflageebene 7 befindliche Auflageebene 8 definieren.Like the side view of the FIG. 4 it can be seen, are the support surfaces 4a, 4b, 4c and 4d, starting from the free end of the spring arms 2a to 2d, which define the support plane 7 in resting under load pad or mattress, obliquely upward at an acute angle out of the support plane, such that the corner regions of the support surfaces lying opposite the spring elements 2a to 2d define a support plane 8 situated above the support plane 7.

Bei unbelasteter Polsterauflage oder Matratze wird diese durch die erfindungsgemäße Gestaltung des Lagerelementes bis zu der Auflageebene 8 angehoben, so dass sie nur von den punktförmigen Eckbereichen der Auflageflächen 4a bis 4d getragen wird.With unloaded padding or mattress it is raised by the inventive design of the bearing element up to the support plane 8, so that it is supported only by the point-shaped corner regions of the support surfaces 4a to 4d.

Natürlich ist die erfindungsgemäße Ausgestaltung des Lagerelementes nicht auf die in den Abbildungen dargestellte Ausführungsform beschränkt. Selbstverständlich können die Auflageflächen 4a, 4b, 4c und 4d auch eine andere Grundrissgestaltung aufweisen, so dass sich ggf. linienförmige Auflagezonen für die Polsterauflage oder Matratze im unbelasteten Zustand ergeben.Of course, the inventive design of the bearing element is not limited to the embodiment shown in the figures. Of course, the bearing surfaces 4a, 4b, 4c and 4d may also have a different floor plan design, so that, if appropriate, linear support zones for the upholstered mattress or mattress in the unloaded state result.
