Definitions
- the invention relates to a suspension mat, in particular for the suspension of seats and the like according to the preamble of claim 1.
- Such suspension elements have so far mostly been formed by the upholstery of seats, beds or the like, which in this respect have the task of giving the user the impression of a soft seat.
- the present invention is based on the object of producing the desired impression of a soft sitting in an alternative manner.
- the suspension mat consists of elastic spring elements, which are arranged next to each other in one direction in any direction and transverse to this Direction. This creates the impression of soft sitting without any additional aids. This is because, like an upholstery, an element with an elastic surface and suitable spring comfort is achieved. However, if a three-dimensional spring-elastic element is desired, the mat can also extend in the third dimension. Nevertheless, the elements can be used independently of other parts of the seat, which is particularly advantageous when recycling the vehicle after its useful life has ended.
- the spring element consists of metallic helical springs which are turned into one another with their spirals or helices, so that in addition to the suspension in the longitudinal direction there is an operative connection transverse to the longitudinal extension of the springs.
- metallic spring band steels can also be used, which are arranged next to one another and are connected to one another transversely thereto by cross struts or flat connecting means. A flat power transmission is guaranteed in both cases.
- FIG. 2 is a side view of the suspension mat of FIG. 1,
- FIG. 3 shows a representation according to FIG. 2 in a plastically deformed position
- FIG. 4 a suspension mat in a further embodiment in section and in plan view
- FIG. 6 a suspension mat in section as a composite material
- FIG. 7 shows a section through a spring element, Fig. 8-10 a preferably metallic suspension mat in another
- suspension mat preferably made of plastic, in a further embodiment in section, in plan view and in a three-dimensional view.
- FIG. 1 shows a top view of a suspension mat 10, as is used in particular for the suspension of seats, preferably vehicle seats.
- the use of the suspension mat is not limited to the seat and backrests of all types of seating such as office chairs, seating elements, sofas or vehicle and airplane seats, but can e.g. can also be used for beds or bicycle saddles.
- the mesh base is suitable for all types of use where elastic, pressure point-free mesh base is required.
- spring elements 11 are arranged next to one another, which are connected to one another transversely to their longitudinal extension, that is to say to the first direction, for operative connection to one another.
- the first direction runs parallel to a surface of the seating, the bed or the like which can be used by a user.
- the spring elements 11, 11 ', 12, 15 are preferably metallic and can therefore be easily reused later.
- the mat is at best flame-retardant and non-flammable due to the upper material, which is particularly important in vehicle and aircraft construction.
- other materials can also be used, provided the desired elastic properties are achieved the desired elastic properties can be achieved.
- the spring elements can be arranged next to one another in any desired manner, provided that it is only ensured that a suitable force transmission is achieved to achieve the desired spring comfort, namely the impression of a soft sitting in the seat.
- the spring elements 11, 11 ', 12, 15 are preferably arranged essentially parallel to one another, as is also illustrated in FIG. 1.
- Such a suspension mat will usually be a flat structure. However, if a three-dimensional spring-elastic element is desired, the mat can also extend in the third dimension. In this case, a connection between different spring elements can also take place in the third dimension.
- the spring elements 11 according to FIG. 1 are coil springs, the spirals of which are rotated into one another in order to achieve the operative connection.
- the coil springs are parallel to each other.
- the spirals of the coil springs collide as shown in FIGS. 2 and 3 and produce the desired flat or, if necessary, three-dimensional effect by transmitting the forces to one another transversely to the longitudinal extension of the coil springs.
- FIG. 2 there is a relatively soft support with four support points in the illustration.
- the width of the coil springs is the width x, while they have a height y.
- the mat or also the coil springs can be plastically deformed as spring elements 11 'transversely to the surface in which the suspension mat 10 comes to lie.
- FIG. 3 On the one hand, the number of support points has increased from four to eight, at the same time the mat has become 25% wider, while the overall height has been reduced to y '.
- Such a mat is fundamentally harder than the suspension mat according to FIG. 2.
- Figures 4 to 13 show spring elements that can be used either in connection with the coil springs 10 or by themselves.
- These spring elements 12 consist in the exemplary embodiments of FIGS. 4 to 10 of spring steel with a width u.
- the spring band steel is bent up to a height v in a loop.
- the height v or y 'of the spring mat can be reduced to less than 10 mm in height without losing the desired sitting or lying feeling. Any construction heights are possible, but construction heights of 8 to 20 mm, preferably 10 mm, are preferred.
- these spring elements 12, like the spring elements of the first exemplary embodiment 11, 11 ′ can be connected to one another by a flat connecting means 13 (FIG. 6).
- the connecting means can be glued to the spring elements. It can be arranged on one side or on both sides of the suspension mat 10 with the spring elements 11, 11 ', 12. In principle, e.g. the central lanyard is in operative connection on both sides with spring elements.
- the connecting means 13 can e.g. in the form of a mesh, a layer, a mat or a film. However, a three-dimensional structure can also be achieved here by corresponding arrangement of spring elements and connecting means.
- the spring elements can also be connected to one another by preferably elastic cross struts 14.
- This connection by cross struts 14 is particularly suitable when spring band steel is used as spring element 12.
- spring band steel is used as spring element 12.
- the spring steel according to FIG. 4 has a different bending radius than the spring band steel in FIG. 7. This can also be used to influence the elasticity of the suspension mat.
- the spring mat as spring elements 12 has a plurality of strips of any width and length.
- plastics or other elastic materials can also be used, although preference is given to the metallic spring element.
- the individual strips can be connected to the connecting means 13, 14 in a wide variety of ways.
- the spring elements 10, 11 ', 12 can also e.g. be assembled as a plastic injection molded part.
- a corresponding embodiment is shown in FIGS. 11 to 13.
- the spring elements 15 rise from a base area 16.
- a corresponding part can be injection molded or also deep-drawn from a plastic part - or also a metallic part - with plastic deformation of the plastic.
- the mat In both cases, due to the close and high number of support points in the direction of the "to be owned” area, a full-surface seating feeling without noticeable pressure points can be achieved in contrast to previously known spring mattresses.
- the mat nevertheless adapts to the load due to the composition of individual elements every body shape on a comparable water bed, but unlike a water bed, the mat is breathable and heatable.
- the suspension mat 10 consisting of the spring elements 11, 11 ', 12 and possibly the connecting means 13, 14 can be constructed as a composite material which is used for use in seats, in particular in vehicle seats.
- This composite material can in turn comprise parts of the vehicle seat, such as the upholstery.
- the composite material can be an integral part of the vehicle seat or of parts of the vehicle seat.
- the spring mat can be made in all sizes and shapes such as rectangular, square, oval, round, triangular, etc.
- the mat can be produced with defined sink depths and hardnesses at any point, since only a corresponding selection of the spring elements or their shape is required for these points or at these points.
- the mat is very flexible and adapts to all possible basic shapes depending on the application.
- the mat does not have to be plastically deformed, for example by folding, bending or the like.
- the mat follows any basic contour. Additional brackets and / or shaped frames can be used, but are not absolutely necessary. Coiled springs lying together as in the first embodiment of FIGS. 1 to 3 cannot be used as flexibly. In particular, the mat according to FIGS. 4 to 13 does not lose its outer contour when subjected to pressure, since the pressure is absorbed by the shape of the individual spring elements.

Beschreibungdescription
Die Erfindung betrifft eine Federungsmatte, insbesondere zur Unterfederung von Sitzen und dergleichen nach dem Oberbegriff des Anspruches 1.The invention relates to a suspension mat, in particular for the suspension of seats and the like according to the preamble of claim 1.
Derartige Federungselemente werden bisher meist durch die Polsterung von Sitzen, Betten oder dergleichen gebildet, die insofern die Aufgabe haben, beim Benutzer den Eindruck eines weichen Einsitzens zu erwecken.Such suspension elements have so far mostly been formed by the upholstery of seats, beds or the like, which in this respect have the task of giving the user the impression of a soft seat.
Im Bettenbereich ist die Anordnung von senkrecht zur Liegefläche stehenden Fe- derelementen in Matratzen und Bettenrosten bekannt. Diese Federelemente sind jedoch für den Benutzer spürbar, so dass sich kein flächiger Eindruck ergibt.The arrangement of spring elements in mattresses and bed frames that are perpendicular to the lying surface is known in the bed area. However, these spring elements can be felt by the user, so that there is no flat impression.
Zusammenfassung der ErfindungSummary of the invention
Ausgehend von diesem Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, den gewünschten Eindruck eines weichen Einsitzens auf alternative Weise zu erzeugen.Starting from this prior art, the present invention is based on the object of producing the desired impression of a soft sitting in an alternative manner.
Diese Aufgabe wird durch eine Federungsmatte mit den Merkmalen des Anspru- ches 1 gelöst.This object is achieved by means of a suspension mat with the features of claim 1.
Die Federungsmatte besteht aus elastischen Federelementen, die in beliebiger Anordnung nebeneinander in einer Richtung angeordnet sind und quer zu dieser
Richtung miteinander in Verbindung stehen. Dadurch ist ohne weitere Hilfsmittel der Eindruck des weichen Einsitzens zu erzeugen. Erzielt wird nämlich wie bei einem Polster ein in der Fläche elastisches Element mit einem geeigneten Federkomfort. Wird jedoch ein dreidimensionales federelastisches Element gewünscht, kann sich die Matte auch in der dritten Dimension erstrecken. Gleichwohl können die Elemente unabhängig von anderen Teilen des Sitzes eingesetzt werden, was insbesondere beim Wiederverwerten des Fahrzeugs nach Ende seiner Nutzdauer von Vorteil ist.The suspension mat consists of elastic spring elements, which are arranged next to each other in one direction in any direction and transverse to this Direction. This creates the impression of soft sitting without any additional aids. This is because, like an upholstery, an element with an elastic surface and suitable spring comfort is achieved. However, if a three-dimensional spring-elastic element is desired, the mat can also extend in the third dimension. Nevertheless, the elements can be used independently of other parts of the seat, which is particularly advantageous when recycling the vehicle after its useful life has ended.
In einer Ausgestaltung besteht das Federelement aus metallischen Schraubenfedern, die mit ihren Spiralen oder Wendel ineinander gedreht sind, so dass sich außer der Federung in Längsrichtung eine Wirkverbindung quer zur Längserstreckung der Federn ergibt. Alternativ können aber auch metallische Federbandstähle verwendet werden, die nebeneinander angeordnet sind und quer dazu durch Querstreben oder flächige Verbindungsmittel miteinander verbunden sind. In beiden Fällen wird eine flächige Kraftübertragung gewährleistet.In one embodiment, the spring element consists of metallic helical springs which are turned into one another with their spirals or helices, so that in addition to the suspension in the longitudinal direction there is an operative connection transverse to the longitudinal extension of the springs. Alternatively, however, metallic spring band steels can also be used, which are arranged next to one another and are connected to one another transversely thereto by cross struts or flat connecting means. A flat power transmission is guaranteed in both cases.
Weitere Vorteile ergeben sich aus den Unteransprüchen.Further advantages result from the subclaims.

Ausführliche Beschreibung bevorzugter AusführungsbeispieleDetailed description of preferred embodiments
Die Erfindung wird jetzt beispielhaft unter bezug auf die beigefügten Zeichnungen näher erläutert. Allerdings handelt es sich bei den Ausführungsbeispielen nur um Beispiele, die nicht das erfinderische Konzept auf eine bestimmte Anordnung beschränken sollen.The invention will now be explained in more detail by way of example with reference to the accompanying drawings. However, the exemplary embodiments are only examples which are not intended to restrict the inventive concept to a specific arrangement.
Figur 1 zeigt in Draufsicht eine Federungsmatte 10, wie sie insbesondere zur Unterfederung von Sitzen, vorzugsweise von Fahrzeugsitzen eingesetzt wird. Die Anwendung der Federungsmatte ist jedoch nicht auf Sitzfläche und Rückenlehnen von Bestuhlungen aller Art wie Bürostühle, Sitzelemente, Sofas oder Fahrzeug- und Flugzeugsitze beschränkt, sondern kann z.B. auch für Betten oder Fahrradsattel eingesetzt werden. Grundsätzlich eignet sich die Unterfederungsmatte für alle Einsatzarten, bei denen es auf eine elastische, druckpunktfreie Unterfederung von Flächen ankommt.FIG. 1 shows a top view of a suspension mat 10, as is used in particular for the suspension of seats, preferably vehicle seats. However, the use of the suspension mat is not limited to the seat and backrests of all types of seating such as office chairs, seating elements, sofas or vehicle and airplane seats, but can e.g. can also be used for beds or bicycle saddles. Basically, the mesh base is suitable for all types of use where elastic, pressure point-free mesh base is required.
Bei dieser Unterfederungsmatte sind Federelemente 11 nebeneinander angeordnet, die quer zu ihrer Längserstreckung, also zur ersten Richtung miteinander zur Wirkverbindung miteinander verbunden sind. Die erste Richtung verläuft parallel zu einer von einem Benutzer benutzbaren Fläche der Bestuhlung, des Betts oder dergleichen. Die Federelemente 11, 11', 12, 15 sind vorzugsweise metallisch und damit problemlos später wiederverwertbar. Insbesondere bei einer metallischen Ausgestaltung ist die Matte - aufgrund des Obermaterials - allenfalls schwer entflammbar und nicht brennbar, was vor allem im Fahrzeug- und Flugzeugbau von Bedeutung ist. Es können aber auch andere Materialien eingesetzt werden, sofern die gewünschten elastischen Eigenschaften erzielt
die gewünschten elastischen Eigenschaften erzielt werden. Grundsätzlich können die Federelemente in beliebiger Weise nebeneinander angeordnet werden, sofern lediglich gewährleistet ist, dass eine geeignete Kraftübertragung zur Erzielung des gewünschten Federkomforts, nämlich des Eindrucks eines weichen Einsitzens in den Sitz, gewährleistet wird. Vorzugsweise sind die Federelemente 11, 11', 12, 15 im Wesentlichen parallel zueinander angeordnet, wie dies auch Fig. 1 verdeutlicht.In this spring suspension mat, spring elements 11 are arranged next to one another, which are connected to one another transversely to their longitudinal extension, that is to say to the first direction, for operative connection to one another. The first direction runs parallel to a surface of the seating, the bed or the like which can be used by a user. The spring elements 11, 11 ', 12, 15 are preferably metallic and can therefore be easily reused later. In particular in the case of a metallic design, the mat is at best flame-retardant and non-flammable due to the upper material, which is particularly important in vehicle and aircraft construction. However, other materials can also be used, provided the desired elastic properties are achieved the desired elastic properties can be achieved. In principle, the spring elements can be arranged next to one another in any desired manner, provided that it is only ensured that a suitable force transmission is achieved to achieve the desired spring comfort, namely the impression of a soft sitting in the seat. The spring elements 11, 11 ', 12, 15 are preferably arranged essentially parallel to one another, as is also illustrated in FIG. 1.
Einer derartige Federungsmatte wird meist ein flächiges Gebilde sein. Wird jedoch ein dreidimensionales federelastisches Element gewünscht, kann sich die Matte auch in der dritten Dimension erstrecken. In diesem Fall kann eine Verbindung zwischen verschiedenen Federelementen auch in der dritten Dimension erfolgen.Such a suspension mat will usually be a flat structure. However, if a three-dimensional spring-elastic element is desired, the mat can also extend in the third dimension. In this case, a connection between different spring elements can also take place in the third dimension.
Die Federelemente 11 gemäß Fig. 1 sind im Ausgangszustand Schraubenfedern, deren Spiralen zur Erzielung der Wirkverbindung ineinander gedreht sind. Mit an- deren Worten liegen die Schraubenfedern parallel nebeneinander. Erfolgt jedoch eine Belastung normal zur Fläche der Federungsmatte, so stoßen wie in den Figuren 2 und 3 dargestellt, die Spiralen der Schraubenfedern aneinander und erzeugen die gewünschte flächige oder bedarfsweise auch dreidimensionale Wirkung, indem sie die Kräfte aufeinander quer zur Längserstreckung der Schraubenfedern übertragen.In the initial state, the spring elements 11 according to FIG. 1 are coil springs, the spirals of which are rotated into one another in order to achieve the operative connection. In other words, the coil springs are parallel to each other. However, if there is a load normal to the surface of the suspension mat, the spirals of the coil springs collide as shown in FIGS. 2 and 3 and produce the desired flat or, if necessary, three-dimensional effect by transmitting the forces to one another transversely to the longitudinal extension of the coil springs.
Bei einer Ausgestaltung gemäß Fig. 2 ergibt sich eine verhältnismäßig weiche Auflage mit in der Darstellung vier Auflagepunkten. Die Breite der Spiralfedern ist die Breite x, während sie eine Höhe y aufweisen. Um die Federung härter zu machen und gleichzeitig die Bauhöhe zu reduzieren, können die Matte oder auch die Schraubenfedern als Federelemente 11' quer zur Fläche, in der die Federungsmatte 10 zu liegen kommt, plastisch verformt sein. Dies führt zu einer Darstellung gemäß Fig. 3. Einerseits hat sich die Anzahl der Auflagepunkte von vier auf acht erhöht, gleichzeitig ist die Matte um 25 % breiter geworden, während sich die Bauhöhe auf y' reduziert hat. Eine derartige Matte ist grundsätzlich härter wie die Federungsmatte gemäß Fig. 2. Grundsätzlich spricht auch nichts dagegen, einen Teil der Spiralfedern in der Ausgangsform zu lassen, während ein anderer Teil der Spiralfedern mehr oder weniger verformt wird. Dadurch kann gezielt ein
Spiralfedern mehr oder weniger verformt wird. Dadurch kann gezielt ein bestimmtes Federungsverhalten auch innerhalb der Fläche erreicht werden.In a configuration according to FIG. 2, there is a relatively soft support with four support points in the illustration. The width of the coil springs is the width x, while they have a height y. In order to make the suspension harder and at the same time reduce the overall height, the mat or also the coil springs can be plastically deformed as spring elements 11 'transversely to the surface in which the suspension mat 10 comes to lie. This leads to a representation according to FIG. 3. On the one hand, the number of support points has increased from four to eight, at the same time the mat has become 25% wider, while the overall height has been reduced to y '. Such a mat is fundamentally harder than the suspension mat according to FIG. 2. Basically, there is no reason not to leave part of the coil springs in the original shape, while another part of the coil springs is more or less deformed. This can be targeted Coil springs are more or less deformed. In this way, a specific suspension behavior can also be achieved within the surface.
Die Figuren 4 bis 13 zeigen Federelemente, die entweder in Verbindung mit den Schraubenfedern 10 oder für sich eingesetzt werden können. Diese Federelemente 12 bestehen In den Ausführungsbeispielen der Fig. 4 bis 10 aus Federbandstahl mit einer Breite u. Zur Erzielung einer besseren Federwirkung wird der Federbandstahl zu einer Höhe v schleifenförmig aufgebogen. Die Höhe v bzw. y' der Federmatte kann ohne Verlust des angestrebten Sitz- oder Liegegefühls bis auf unter 10mm an Aufbauhöhe reduziert werden. Es sind zwar beliebige Bauhöhen möglich, bevorzugt werden jedoch Bauhöhen von 8 bis 20 mm, vorzugsweise 10mm. Zur Erzielung einer Wirkverbindung können diese Federelemente 12 wie auch die Federelemente des ersten Ausführungsbeispiels 11, 11' durch ein flächiges Verbindungsmittel 13 miteinander verbunden sein (Fig. 6). Das Verbindungs- mittel kann mit den Federelementen verklebt sein. Es kann auf einer Seite oder auf beiden Seiten der Federungsmatte 10 mit den Federelementen 11, 11', 12 angeordnet sein. Grundsätzlich kann auch ein z.B. mittiges Verbindungsmittel beid- seitig mit Federelementen in Wirkverbindung stehen. Das Verbindungsmittel 13 kann z.B. in Form eines Geflechts, einer Schicht, einer Matte oder einer Folie ge- bildet sein. Auch hier lässt sich jedoch auch ein dreidimensionales Gebilde durch entsprechende Anordnung von Federelementen und Verbindungsmitteln erreichen.Figures 4 to 13 show spring elements that can be used either in connection with the coil springs 10 or by themselves. These spring elements 12 consist in the exemplary embodiments of FIGS. 4 to 10 of spring steel with a width u. In order to achieve a better spring action, the spring band steel is bent up to a height v in a loop. The height v or y 'of the spring mat can be reduced to less than 10 mm in height without losing the desired sitting or lying feeling. Any construction heights are possible, but construction heights of 8 to 20 mm, preferably 10 mm, are preferred. To achieve an operative connection, these spring elements 12, like the spring elements of the first exemplary embodiment 11, 11 ′, can be connected to one another by a flat connecting means 13 (FIG. 6). The connecting means can be glued to the spring elements. It can be arranged on one side or on both sides of the suspension mat 10 with the spring elements 11, 11 ', 12. In principle, e.g. the central lanyard is in operative connection on both sides with spring elements. The connecting means 13 can e.g. in the form of a mesh, a layer, a mat or a film. However, a three-dimensional structure can also be achieved here by corresponding arrangement of spring elements and connecting means.
Alternativ oder ergänzend können die Federelemente aber auch durch vorzugs- weise elastische Querstreben 14 miteinander verbunden sein. Diese Verbindung durch Querstreben 14 ist insbesondere beim Einsatz von Federbandstahl als Federelement 12 geeignet. Auch bei Verwendung von Federbandstahl besteht wie bei den Schraubenfedern die Möglichkeit, die Federverhältnisse durch Verwendung unterschiedlicher Materialstärken über die Sitzfläche hinweg unterschiedlich hart oder weich auszugestalten. Mit anderen Worten können also unterschiedliche Federbandstähle nebeneinander eingesetzt werden. Der Federbandstahl gemäß
Fig. 4 weist einen anderen Biegeradius als der Federbandstahl in Fig. 7 auf. Auch damit lässt sich die Elastizität der Federungsmatte beeinflussen.Alternatively or in addition, the spring elements can also be connected to one another by preferably elastic cross struts 14. This connection by cross struts 14 is particularly suitable when spring band steel is used as spring element 12. Even with the use of spring steel, as with the coil springs, there is the option of making the spring ratios hard or soft by using different material thicknesses across the seat. In other words, different spring steel strips can be used next to each other. The spring steel according to FIG. 4 has a different bending radius than the spring band steel in FIG. 7. This can also be used to influence the elasticity of the suspension mat.
In den Ausführungsbeispielen der Fig. 4 bis 10 weist die Federmatte als Feder- elemente 12 mehrere Streifen in beliebigen Breiten und Längen auf. Anstelle des Federstahls könne auch Kunststoffe oder andere elastische Materialien verwendet werden, wenngleich dem metallischen Federelement der Vorzug gegeben wird. Die einzelnen Streifen können mit den Verbindungsmitteln 13,14 auf verschiedenste Weise verbunden sein. Zur Verbindung zwischen den Federelementen 12 und den Verbindungselementen 14 bietet sich z.B. eine Lochnietung oder eine Laserschweißung an. Die Federelemente 10,11 ',12 können aber auch z.B. als Kunststoff-Spritzgussteil zusammengesetzt sein. Eine entsprechende Ausführungsform ist in den Fig. 11 bis 13 dargestellt. Aus einer Grundfläche 16 erheben sich die Federelemente 15. Ein entsprechendes Teil kann spritzgegossen oder auch aus einem Kunststoffteil - oder auch metllischen Teil - unter plastischer Verformung des Kunststoffs tiefgezogen werden.In the exemplary embodiments in FIGS. 4 to 10, the spring mat as spring elements 12 has a plurality of strips of any width and length. Instead of spring steel, plastics or other elastic materials can also be used, although preference is given to the metallic spring element. The individual strips can be connected to the connecting means 13, 14 in a wide variety of ways. For the connection between the spring elements 12 and the connecting elements 14, e.g. hole riveting or laser welding. The spring elements 10, 11 ', 12 can also e.g. be assembled as a plastic injection molded part. A corresponding embodiment is shown in FIGS. 11 to 13. The spring elements 15 rise from a base area 16. A corresponding part can be injection molded or also deep-drawn from a plastic part - or also a metallic part - with plastic deformation of the plastic.
In beiden Fällen kann durch die eng anliegende und hohe Anzahl an Auflagepunkten in Richtung auf die zu „besitzende" Fläche ein vollflächiges Sitzgefühl ohne spürbare Druckpunkte im Gegensatz zu vorbekannten Federmatratzen erreicht werden. Die Matte passt sich bei Belastung aber dennoch in Folge der Zusammensetzung aus Einzelelementen jeder Körperform an vergleichbar einem Wasserbett. Im Gegensatz zu einem Wasserbett ist die Matte aber luftdurchlässig und beheizbar.In both cases, due to the close and high number of support points in the direction of the "to be owned" area, a full-surface seating feeling without noticeable pressure points can be achieved in contrast to previously known spring mattresses. The mat nevertheless adapts to the load due to the composition of individual elements every body shape on a comparable water bed, but unlike a water bed, the mat is breathable and heatable.
Die Federungsmatte 10 bestehend aus den Federelementen 11, 11', 12 und ggf. den Verbindungsmitteln 13, 14 kann als Verbundwerkstoff aufgebaut werden, der zur Verwendung in Sitzen, insbesondere in Fahrzeugsitzen eingesetzt wird. Dieser Verbundwerkstoff kann seinerseits wiederum Teile des Fahrzeugssitzes wie z.B. die Aufpolsterung umfassen. Ebenso kann der Verbundwerkstoff integraler Bestandteil des Fahrzeugssitzes oder von Teilen des Fahrzeugsitzes sein.
Die Federmatte kann in allen Größen und Formen wie z.B. rechteckig, quadratisch, oval, rund, dreieckig usw. gefertigt werden. Die Matte kann mit definierten Einsinktiefen und Härten an beliebigen Punkten hergestellt werden, da dazu nur eine entsprechende Auswahl der Federelemente oder ihrer Form für diese Punkte bzw. an diesen Punkten erforderlich ist. Die Matte ist sehr flexibel und passt sich je nach Einsatzbereich allen möglichen Grundformen an. Dazu muss die Matte nicht zusätzlich plastisch verformt werden, z.B. durch Abkanten, Biegen oder dergleichen. Die Matte folgt einer beliebigen Grundkontur. Zusätzliche Halterungen und/oder geformte Rahmen können zwar verwendet werden, sind aber nicht un- bedingt erforderlich. Zusammenliegende Spiralfedern wie nach dem ersten Ausführungsbeispiel der Fig. 1 bis 3 können nicht so flexibel eingesetzt werden. Insbesondere die Matte nach den Fig. 4 bis 13 verliert bei Druckbelastung ihre Außenkontur nicht, da der Druck durch die Formgebung der einzelnen Federelemente aufgenommen wird.The suspension mat 10 consisting of the spring elements 11, 11 ', 12 and possibly the connecting means 13, 14 can be constructed as a composite material which is used for use in seats, in particular in vehicle seats. This composite material can in turn comprise parts of the vehicle seat, such as the upholstery. Likewise, the composite material can be an integral part of the vehicle seat or of parts of the vehicle seat. The spring mat can be made in all sizes and shapes such as rectangular, square, oval, round, triangular, etc. The mat can be produced with defined sink depths and hardnesses at any point, since only a corresponding selection of the spring elements or their shape is required for these points or at these points. The mat is very flexible and adapts to all possible basic shapes depending on the application. For this purpose, the mat does not have to be plastically deformed, for example by folding, bending or the like. The mat follows any basic contour. Additional brackets and / or shaped frames can be used, but are not absolutely necessary. Coiled springs lying together as in the first embodiment of FIGS. 1 to 3 cannot be used as flexibly. In particular, the mat according to FIGS. 4 to 13 does not lose its outer contour when subjected to pressure, since the pressure is absorbed by the shape of the individual spring elements.
Es versteht sich von selbst, dass diese Beschreibung verschiedensten Modifikationen, Änderungen und Anpassungen unterworfen werden kann, die sich im Bereich von Äquivalenten zu den anhängenden Ansprüchen bewegen.
It goes without saying that this description can be subjected to various modifications, changes and adaptations which range from equivalents to the appended claims.
