Description

Die Erfindung betrifft eine motorisch verstellbare Stützeinrichtung der im Oberbegriff des Anspruchs 1 genannten Art für eine Polsterung eines Sitz- und/oder Liegemöbels, insbesondere eine Matratze eines Bettes.The invention relates to a motor-adjustable support means referred to in the preamble of claim 1 for a padding of a seat and / or reclining furniture, in particular a mattress of a bed.

Derartige Stützeinrichtungen sind beispielsweise in Form von Lattenrosten allgemein bekannt und dienen beispielsweise zur flächigen Abstützung einer Matratze eines Bettes.Such support means are generally known, for example, in the form of slatted frames and serve, for example, for the planar support of a mattress of a bed.

Durch DE 199 62 541 C2 ist eine motorisch verstellbare Stützeinrichtung der betreffenden Art bekannt, die ein zueinander parallele Längsholme aufweisendes erstes Stützteil aufweist, das bei der aus der Druckschrift bekannten Stützeinrichtung durch ein ortsfestes mittleres Stützteil gebildet ist. Die bekannte Stützeinrichtung weist ferner weitere Stützteile auf, die durch Antriebsmittel relativ zu dem ersten Stützteil verstellbar sind. Bei der aus der Druckschrift bekannten Stützeinrichtung ist ein erster Längsholm des ersten Stützteiles zur Aufnahme von Teilen der Antriebsmittel als Hohlprofil ausgebildet, wobei der gesamte Antrieb einschließlich eines Antriebsmotors in dem hohlen ersten Längsholm aufgenommen ist. Aufgrund dessen steht der Antriebsmotor in Vertikalrichtung des ersten Längsholmes nicht über den ersten Längsholm über, so daß die bekannte Stützeinrichtung eine äußerst geringe Bauhöhe aufweist. Darüber hinaus weist die aus der Druckschrift bekannte Stützeinrichtung ein sehr ansprechendes Aussehen auf, da sie äußerlich nicht von einer herkömmlichen, nicht motorisch verstellbaren Stützeinrichtung zu unterscheiden ist.From DE 199 62 541 C2 a motor-adjustable support means of the type in question is known, which has a mutually parallel longitudinal beams exhibiting first support member which is formed in the known from the document support means by a stationary central support member. The known support means further comprises further support members which are adjustable by drive means relative to the first support member. In the support device known from the publication, a first longitudinal spar of the first support member for receiving parts of the drive means is formed as a hollow profile, wherein the entire drive is received including a drive motor in the hollow first longitudinal spar. Because of this, the drive motor is not in the vertical direction of the first longitudinal spar over the first longitudinal spar over, so that the known support means has an extremely low height. In addition, the well known from the document support on a very attractive appearance, since it is not externally distinguishable from a conventional non-motorized support means.

Durch WO 96/29970 ist eine motorisch verstellbare Stützeinrichtung für eine Matratze eines Bettes bekannt, die mehrere in Längsrichtung der Stützeinrichtung aufeinanderfolgende Stützteile aufweist, die durch Antriebsmittel relativ zu einem ersten Stützteil verschwenkbar sind. Die Stützteile sind an einem äußeren Rahmen gelagert, dessen Profilhöhe wesentlich größer ist als die Profilhöhe der Stützteile. Bei der aus der Druckschrift bekannten Stützeinrichtung sind Teile des äußeren Rahmens als Hohlprofil ausgebildet, wobei in dem Hohlprofil Teile der Antriebsmittel zur Verstellung der Stützteile relativ zueinander aufgenommen sind. Der Antriebsmotor ist an einer Innenseite eines Teiles des äußeren Rahmens angeordnet.By WO 96/29970 a motor-adjustable support means for a mattress of a bed is known which comprises a plurality of in the longitudinal direction of the support means consecutive support members which are pivotable by drive means relative to a first support member. The support members are mounted on an outer frame whose profile height is substantially greater than the profile height of the support members. In the known from the document support parts of the outer frame are formed as a hollow profile, wherein in the hollow profile parts of the drive means for adjusting the support members are added relative to each other. The drive motor is disposed on an inner side of a part of the outer frame.

Durch DE 695 07 158 T2 und EP 0 788 325 B1 ist jeweils eine motorisch verstellbare Stützeinrichtung für eine Matratze eines Bettes bekannt, die ein Längsholme aufweisendes erstes Stützteil und wenigstens ein zweites Stützteil aufweist, das durch Antriebsmittel relativ zu dem ersten Stützteil verschwenkbar ist. Bei der bekannten Stützeinrichtung ist der Antriebsmotor außerhalb der Grundfläche der Stützeinrichtung angeordnet und an einer rahmenartigen Verlängerung des ersten Stützteiles befestigt.DE 695 07 158 T2 and EP 0 788 325 B1 each discloses a motor-adjustable supporting device for a mattress of a bed which has a first support part having longitudinal members and at least one second support member which can be pivoted by drive means relative to the first support member. In the known support device of the drive motor is arranged outside the base of the support means and fixed to a frame-like extension of the first support member.

Der Erfindung liegt die Aufgabe zugrunde, eine motorisch verstellbare Stützeinrichtung der im Oberbegriff des Anspruchs 1 genannten Art anzugeben, die eine geringe Bauhöhe aufweist und die einfach und kostengünstig herstellbar ist.The invention has for its object to provide a motor-adjustable support means referred to in the preamble of claim 1 species, which has a low profile and easy and inexpensive can be produced.

Diese Aufgabe wird durch die im Anspruch 1 angegebene Lehre gelöst.This object is achieved by the teaching defined in claim 1.

Der Grundgedanke der erfindungsgemäßen Lehre besteht darin, die Antriebsmittel, insbesondere eine Getriebeanordnung der Antriebsmittel, soweit wie möglich in dem hohlen ersten Längsholm des ersten Stützteiles aufzunehmen, den Antriebsmotor jedoch außerhalb des ersten Längsholmes anzuordnen. Dadurch, daß der Antriebsmotor außerhalb des ersten Längsholmes angeordnet ist und sich beispielsweise lediglich ein mit der Abtriebswelle des Antriebsmotors in Drehantriebsverbindung stehendes erstes Getriebeelement in das Innere des ersten Längsholmes erstreckt, sind die räumlichen Freiheiten bei der Wahl der Getriebeanordnung gegenüber einer Ausführungsform, bei der sämtliche Bauteile des Antriebs in dem hohlen Längsholm aufgenommen sind, erhöht. Insbesondere können aufgrund der erfindungsgemäßen Lehre besonders einfache und damit kostengünstige Getriebeanordnungen verwendet werden, so daß die erfindungsgemäße Stützeinrichtung insgesamt besonders einfach und damit kostengünstig herstellbar ist.The basic idea of the teaching according to the invention is to accommodate the drive means, in particular a gear arrangement of the drive means, as far as possible in the hollow first longitudinal spar of the first support member, but to arrange the drive motor outside of the first longitudinal spar. Characterized in that the drive motor is arranged outside of the first longitudinal spar and, for example, only one standing with the output shaft of the drive motor in rotary drive connection first transmission element extends into the interior of the first longitudinal spar, the spatial freedom in choosing the gear arrangement over an embodiment in which all Components of the drive are accommodated in the hollow longitudinal beam increases. In particular, owing to the teaching according to the invention, particularly simple and thus cost-effective gear arrangements can be used, so that the support device according to the invention as a whole is particularly simple and therefore inexpensive to produce.

Dadurch, daß der Antriebsmotor beispielsweise an einer dem anderen Längsholm gegenüberliegenden seitlichen Wandung des ersten Längsholmes, in der die Ausnehmung gebildet ist, angeordnet ist, ist der Antriebsmotor in der Seitenansicht des ersten Längsholmes zumindest teilweise verdeckt und tritt damit optisch nicht in den Hintergrund.Characterized in that the drive motor, for example, on a side opposite the other longitudinal spar side wall of the first longitudinal spar, in which the recess is formed, the drive motor is at least partially hidden in the side view of the first longitudinal spar and thus does not visually in the background.

Dadurch, daß der Antriebsmotor nicht an einem äußeren Rahmen der Stützeinrichtung, sondern vielmehr unmittelbar an einem der Stützteile angeordnet ist, ergibt sich ein besonders kompakter und raumsparender Aufbau.The fact that the drive motor is not arranged on an outer frame of the support means, but rather directly on one of the support members, results in a particularly compact and space-saving design.

Unter einem Stützteil wird erfindungsgemäß ein Bauteil verstanden, das Federungselemente, beispielsweise federnde Latten, zur Abstützung einer Polsterung trägt und bei Abstützung der Polsterung die auftretenden Stützkräfte aufnimmt. Die Stützteile können beispielsweise durch Längsholme der Stützeinrichtung gebildet sein, die über Querholme miteinander verbunden sind und auf ihrer Oberseite Federungselemente, beispielsweise federnde Latten, tragen. Demgegenüber bildet ein äußerer Rahmen beispielsweise eines Lattenrostes, der lediglich zum Einlegen des Lattenrostes in ein Bettgestell dient, jedoch keine Federungselemente trägt, kein Stützteil im Sinne der Erfindung.A support member according to the invention is understood to mean a component which carries suspension elements, for example resilient slats, for supporting a padding and, in support of the padding, absorbs the supporting forces which occur. The support members may be formed for example by longitudinal struts of the support means, which are connected to each other via transverse bars and on its upper side suspension elements, such as resilient slats wear. In contrast, forms an outer frame, for example, a slatted base, which serves only to insert the slatted frame in a bed frame, but does not support suspension elements, no support member according to the invention.

Grundsätzlich ist es erfindungsgemäß möglich, daß der Antriebsmotor mit seinem die Abtriebswelle tragenden Ende teilweise durch die Ausnehmung in das Innere des ersten Längsholmes hineinragt. Zweckmäßigerweise ist der Antriebsmotor jedoch im wesentlichen vollständig außerhalb des ersten Längsholmes angeordnet. Bei dieser Ausführungsform kann beispielsweise lediglich die Abtriebswelle des Antriebsmotors oder das mit der Abtriebswelle in Drehantriebsverbindung stehende erste Getriebeelement in das Innere des ersten Längsholmes hineinragen.In principle, it is possible according to the invention for the drive motor, with its end carrying the output shaft, to project in part through the recess into the interior of the first longitudinal spar. Conveniently, however, the drive motor is arranged substantially completely outside the first longitudinal spar. In this embodiment, for example, only the output shaft of the drive motor or standing with the output shaft in rotary drive connection first transmission element protrude into the interior of the first longitudinal spar.

Erfindungsgemäß kann auch ein ggf. vorgesehener Querholm des ersten Stützteiles als Hohlprofil ausgebildet sein und Teile der Antriebsmittel aufnehmen, wobei die Ausnehmung dann in dem Querholm gebildet und der Antriebsmotor an dem Querholm angeordnet ist.According to the invention, a possibly provided cross member of the first support member may be formed as a hollow profile and receive parts of the drive means, wherein the recess is then formed in the cross member and the drive motor is arranged on the cross member.

Erfindungsgemäß können beliebige geeignete Getriebeanordnungen verwendet werden, wobei die Getriebeanordnung im einfachsten Fall aus lediglich zwei Getriebeelementen besteht, nämlich beispielsweise dem sich durch die Ausnehmung in das Innere des ersten Längsholmes erstreckenden ersten Getriebeelement und dem im Inneren des Längsholmes angeordneten zweiten Getriebeelement. Es ist jedoch auch möglich, an dem im Inneren des ersten Längsholmes angeordneten Teil der Getriebeanordnung und/oder einem außerhalb des Längsholmes angeordneten Teil der Getriebeanordnung zusätzliche Getriebeelemente vorzusehen.According to the invention, any suitable gear arrangements can be used, wherein the gear arrangement consists in the simplest case of only two gear elements, namely, for example, through the recess in the interior of the first longitudinal spar extending first gear element and arranged in the interior of the longitudinal Holmes second gear element. However, it is also possible to provide additional gear elements on the part of the gear arrangement arranged in the interior of the first longitudinal spar and / or a part of the gear arrangement arranged outside the longitudinal spar.

Um einen besonders einfachen und damit kostengünstigen und zugleich robusten Aufbau zu erzielen, sieht eine außerordentlich vorteilhafte Weiterbildung der erfindungsgemäßen Lehre vor, daß das erste Getriebeelement eine Schnecke eines Schneckengetriebes ist, dessen Schneckenrad im Inneren des ersten Längsholmes angeordnet ist und das zweite Getriebeelement bildet. Derartige Schneckengetriebe stehen als einfache und kostengünstige sowie robuste Standardbaugruppen zur Verfügung und ermöglichen bereits in einer Stufe eine hohe Untersetzung. Falls erforderlich, können erfindungsgemäß mehrere Schneckengetriebe hintereinander geschaltet werden. In kinematischer Umkehrung dieser Ausführungsform kann auch das erste Getriebeelement auch ein Schneckenrad eines Schneckengetriebes sein, dessen Schnecke im Inneren des ersten Längsholmes angeordnet ist und das zweite Getriebeelement bildet.To achieve a particularly simple and thus cost-effective and at the same time robust construction, an extraordinarily advantageous development of the teaching according to the invention provides that the first gear element is a worm of a worm gear whose worm wheel is arranged in the interior of the first longitudinal beam and forms the second gear element. Such worm gears are available as simple and cost-effective as well as robust standard modules and already allow a high reduction in one stage. If necessary, several worm gears can be connected in series according to the invention. In a kinematic reversal of this embodiment, the first transmission element may also be a worm wheel of a worm gear, the worm is arranged in the interior of the first longitudinal spar and forms the second transmission element.

Grundsätzlich können bei der vorgenannten Ausführungsform zwischen der Schnecke und der Abtriebswelle des Antriebsmotors noch zusätzliche eine Drehantriebsverbindung zwischen der Schnecke und der Abtriebswelle herstellende Getriebeelemente vorgesehen sein. Um einen besonders einfachen und damit kostengünstigen Aufbau zu erzielen, ist es jedoch zweckmäßig, daß die Schnecke drehfest mit der Abtriebswelle des Antriebsmotors verbunden ist, insbesondere an die Abtriebswelle des Antriebsmotors angeformt ist.In principle, in the abovementioned embodiment, additional gear elements which produce a rotary drive connection between the worm and the output shaft can be provided between the worm and the output shaft of the drive motor. In order to achieve a particularly simple and thus cost-effective construction, it is expedient, however, for the worm to be connected in a rotationally fixed manner to the output shaft of the drive motor, in particular to be molded onto the output shaft of the drive motor.

Um eine besonders geringe Bauhöhe der erfindungsgemäßen Stützeinrichtung zu erzielen, sieht eine besonders vorteilhafte Weiterbildung der erfindungsgemäßen Lehre vor, daß der Antriebsmotor in der Seitenansicht im wesentlichen vollständig innerhalb der Profilhöhe des ersten Längsholmes liegt, derart, daß der Antriebsmotor in Vertikalrichtung nicht oder nur unwesentlich über dem ersten Längsholm übersteht.In order to achieve a particularly low overall height of the support device according to the invention, provides a particularly advantageous development of the teaching according to the invention that the drive motor in the side view is substantially completely within the profile height of the first longitudinal spar, such that the drive motor in the vertical direction not or only slightly above the first longitudinal spar protrudes.

Zweckmäßigerweise tragen die Stützteile Federelemente, insbesondere federnde Latten, auf denen sich bei Benutzung der Stützeinrichtung die Polsterung des Sitz- und/oder Liegemöbels abstützt. Form, Größe und Anzahl der Federelemente sind entsprechend den jeweiligen Anforderungen in weiten Grenzen wählbar.Conveniently, the support members carry spring elements, in particular resilient slats on which the padding of the seat and / or reclining furniture is supported when using the support means. Shape, size and number of spring elements can be selected within wide limits according to the respective requirements.

Die Übertragung des Antriebsdrehmomentes des Antriebsmotors auf ein zu verstellendes Stützteil kann auf beliebige geeignete Weise erfolgen. Eine vorteilhafte Weiterbildung sieht vor, daß der Antriebsmotor in Antriebsverbindung mit einem linear beweglichen Antriebselement steht, das im Inneren des ersten Längsholmes angeordnet ist und mit einem zu verstellenden Stützteil in Wirkungsverbindung steht. Bei dieser Ausführungsform wird die Drehbewegung der Abtriebswelle des Antriebsmotors in eine Linearbewegung des linear beweglichen Antriebselementes umgesetzt. Bei dieser Ausführungsform läßt sich auf besonders einfache Weise beispielsweise eine Schwenkbewegung einer mit einem zu verstellenden Stützteil drehfest verbundenen Welle erzielen.The transmission of the drive torque of the drive motor to a support member to be adjusted can be done in any suitable manner. An advantageous development provides that the drive motor is in drive connection with a linearly movable drive element, which is arranged in the interior of the first longitudinal spar and is in operative connection with a support member to be adjusted. In this embodiment, the rotational movement of the output shaft of the drive motor is converted into a linear movement of the linearly movable drive element. In this embodiment, for example, a pivoting movement of a rotatably connected to a support member to be adjusted shaft can be achieved in a particularly simple manner.

Eine Weiterbildung der vorgenannten Ausführungsform sieht vor, daß das linear bewegliche Antriebselement eine Spindelmutter ist, die verdrehsicher und in Axialrichtung beweglich auf eine Gewindespindel angeordnet ist, die mit dem Antriebsmotor in Drehantriebsverbindung steht. Bei dieser Ausführungsform erfolgt die Umsetzung der Drehbewegung der Abtriebswelle des Antriebsmotors in eine Linearbewegung durch einen Spindeltrieb. Derartige Spindeltriebe stehen als einfache und kostengünstige Standardbauteile zur Verfügung. Sie sind zur Übertragung großer Kräfte geeignet und besonders robust.A development of the aforementioned embodiment provides that the linearly movable drive element is a spindle nut, which is arranged against rotation and movable in the axial direction on a threaded spindle, with the drive motor in rotary drive connection stands. In this embodiment, the implementation of the rotational movement of the output shaft of the drive motor takes place in a linear movement by a spindle drive. Such spindle drives are available as simple and inexpensive standard components. They are suitable for transmitting large forces and very robust.

In kinematischer Umkehrung der vorgenannten Ausführungsform kann das linear bewegliche Antriebselement auch eine verdrehsicher gelagerte und in ihrer Axialrichtung bewegliche Gewindespindel sein, auf der eine ortsfeste Spindelmutter angeordnet ist, die mit dem Antriebsmotor in Drehantriebsverbindung steht.In kinematic reversal of the aforementioned embodiment, the linearly movable drive member may also be a rotationally mounted and movable in its axial direction threaded spindle, on which a stationary spindle nut is arranged, which is in rotary drive connection with the drive motor.

Bei den beiden vorgenannten Ausführungsformen ist der Spindeltrieb jeweils zweckmäßigerweise im Inneren des ersten Längsholmes angeordnet.In the two aforementioned embodiments, the spindle drive is expediently arranged in each case in the interior of the first longitudinal spar.

Eine andere Weiterbildung der erfindungsgemäßen Lehre sieht vor, daß die Drehachse der Abtriebswelle des Antriebsmotors oder des ersten Getriebeelementes mit der Längsachse des ersten Längsholmes bzw. einer linearen Bewegungsachse des linear beweglichen Antriebselementes einen spitzen Winkel, insbesondere einen Winkel von etwa 90° bildet. Insbesondere dann, wenn der Winkel zwischen der Drehachse des ersten Getriebeelementes und der Längsachse des ersten Längsholmes etwa 90° beträgt, ergibt sich ein besonders einfacher und damit kostengünstiger Aufbau, da die Getriebeanordnung beispielsweise durch ein einfaches Schneckengetriebe gebildet sein kann, wobei die Drehachse der Schnecke und die Drehachse des Schneckenrades etwa senkrecht zueinander stehen.Another development of the teaching of the invention provides that the axis of rotation of the output shaft of the drive motor or the first transmission element with the longitudinal axis of the first longitudinal spar or a linear axis of movement of the linearly movable drive element forms an acute angle, in particular an angle of about 90 °. In particular, when the angle between the axis of rotation of the first gear member and the longitudinal axis of the first longitudinal spar is about 90 °, results in a particularly simple and thus cost-effective structure, since the gear assembly may be formed for example by a simple worm gear, wherein the axis of rotation of the screw and the axis of rotation of the worm wheel are approximately perpendicular to each other.

Um einen kompakten Aufbau mit geringer Bauhöhe zu erzielen, ist es zweckmäßig, daß die Profilhöhe des ersten Längsholmes weniger als 100 mm, vorzugsweise weniger als etwa 85 mm beträgt.In order to achieve a compact construction with low overall height, it is expedient that the profile height of the first longitudinal spar less than 100 mm, preferably less than about 85 mm.

Grundsätzlich kann das erste Stützteil ein bewegliches, beispielsweise relativ zu einem anderen Stützteil verschwenkbares Stützteil sein. Eine Weiterbildung der erfindungsgemäßen Lehre sieht jedoch vor, daß das erste Stützteil ein ortsfestes Stützteil ist. Bei dieser Ausführungsform ist der Antriebsmotor an einem ortsfesten Stützteil angeordnet, so daß er ebenfalls ortsfest ist. Bei dieser Ausführungsform ist der Aufbau besonders einfach und damit kostengünstig gestaltet.In principle, the first support part may be a movable support part which can be pivoted, for example, relative to another support part. However, a development of the teaching according to the invention provides that the first support member is a stationary support member. In this embodiment, the drive motor is arranged on a stationary support member, so that it is also stationary. In this embodiment, the structure is particularly simple and thus designed cost.

Eine andere Weiterbildung der erfindungsgemäßen Lehre sieht vor, daß die Ausnehmung entfernt von den Enden des ersten Längsholmes in dem ersten Längsholm gebildet ist.Another development of the teaching according to the invention provides that the recess is formed away from the ends of the first longitudinal spar in the first longitudinal spar.

Um den Antriebsmotor optisch noch weiter in den Hintergrund treten zu lassen und so den optischen Eindruck der erfindungsgemäßen Stützeinrichtung noch weiter zu verbessern, sieht eine Weiterbildung vor, daß der Antriebsmotor in einer vorzugsweise kastenartigen Verkleidung-aufgenommen ist. Die Verkleidung kann den Antriebsmotor ganz oder im wesentlichen vollständig umgeben und ihn so verdecken.In order to make the drive motor visually even further into the background and thus to further improve the visual impression of the support device according to the invention, a further development provides that the drive motor is accommodated in a preferably box-like casing. The panel may completely or substantially completely surround the drive motor and thus obscure it.

Entsprechend den jeweiligen Anforderungen kann die Verkleidung lösbar mit dem ersten Längsholm verbunden sein oder einstückig mit dem ersten Längsholm ausgebildet sein, wie dies Weiterbildungen der erfindungsgemäße Lehre vorsehen.According to the respective requirements, the covering can be releasably connected to the first longitudinal spar or be integrally formed with the first longitudinal spar, as provided by developments of the teaching according to the invention.

Zweckmäßigerweise ist die Stützeinrichtung als Lattenrost ausgebildet, wie dies eine Weiterbildung vorsieht.Conveniently, the support device is designed as a slatted base, as this provides for a further development.

Die Erfindung wird nachfolgend anhand der beigefügten Zeichnung näher erläutert, in der Ausführungsbeispiele einer erfindungsgemäßen Stützeinrichtung dargestellt sind.

In den Figuren der Zeichnung sind gleiche bzw. sich entsprechende Bauteile mit den gleichen Bezugszeichen versehen.In the figures of the drawing are the same or corresponding components provided with the same reference numerals.

In Fig. 1 ist ein erstes Ausführungsbeispiel einer erfindungsgemäßen motorisch verstellbaren Stützeinrichtung 2 für eine Polsterung eines Sitz- und/oder Liegemöbels dargestellt, die bei diesem Ausführungsbeispiel zum Abstützen einer Matratze eines Bettes dient. Die Stützeinrichtung 2 weist mehrere in Längsrichtung der Stützeinrichtung 2 aufeinanderfolgende Stützteile auf. Bei diesem Ausführungsbeispiel weist die Stützeinrichtung 2 im einzelnen ein erstes Stützteil 4 auf, das bei diesem Ausführungsbeispiel ein ortsfestes mittleres Stützteil der Stützeinrichtung 2 bildet und mit einem äußeren Rahmen 6 der Stützeinrichtung 2 verbunden ist. Mit einer Seite des mittleren Stützteiles 4 ist gelenkig und um eine horizontale Schwenkachse verschwenkbar ein Lordosenstützteil 8 verbunden, mit dessen dem mittleren Stützteil 4 abgewandter Seite gelenkig und um eine horizontale Schwenkachse verschwenkbar ein Oberkörperstützteil 10 verbunden ist, mit dessen dem Lordosenstützteil 8 abgewandter Seite gelenkig und um eine horizontale Schwenkachse verschwenkbar ein Kopfstützteil 12 verbunden ist.In Fig. 1, a first embodiment of a motor-adjustable support device 2 according to the invention for a padding of a seat and / or reclining furniture is shown, which serves in this embodiment for supporting a mattress of a bed. The support device 2 has a plurality of support members 2 consecutive in the longitudinal direction of the support means. In this embodiment, the support means 2 in detail on a first support member 4, which forms a stationary central support member of the support means 2 in this embodiment and is connected to an outer frame 6 of the support means 2. With one side of the central support member 4 is articulated and pivotable about a horizontal pivot axis a Lordosenstützteil 8 connected to the middle support member 4 side facing pivotally and about a horizontal pivot axis pivotally connected to an upper body support member 10, with the lumbar support member 8 side facing away and pivotable about a horizontal pivot axis, a headrest part 12 is connected.

Mit der dem Lordosenstützteil 8 abgewandten Seite des mittleren Stützteiles 4 ist gelenkig und um eine horizontale Schwenkachse schwenkbar ein Beinstützteil 14 verbunden, mit dessen dem mittleren Stützteil 4 abgewandter Seite gelenkig und um eine horizontale Schwenkachse verschwenkbar ein Wadenstützteil 16 verbunden ist.With the lordosis support 8 side facing away from the central support member 4 is pivotally connected to a horizontal pivot axis and a leg support member 14, with the middle support member 4 opposite side pivotally and about a horizontal pivot axis pivotally a calf support member 16 is connected.

Zum Verstellen der Stützteile 8, 10, 12, 14, 16 relativ zueinander bzw. relativ zu dem mittleren Stützteil 4 sind weiter unten näher erläuterte elektromotorische Antriebsmittel vorgesehen. Spannungsversorgungs- und Steuermittel zur Spannungsversorgung bzw. Ansteuerung der Antriebsmittel sind in der Zeichnung nicht dargestellt.For adjusting the support members 8, 10, 12, 14, 16 relative to each other or relative to the central support member 4 further explained below electromotive drive means are provided. Power supply and control means for power supply or control of the drive means are not shown in the drawing.

Die Stützteile 4, 8, 10, 12, 14, 16 tragen auf ihrer Oberseite Federelemente, die bei diesem Ausführungsbeispiel durch federnde Latten gebildet sind, von denen in der Zeichnung lediglich eine Latte mit dem Bezugszeichen 18 versehen ist. Unter Stützteilen werden erfindungsgemäß diejenigen Teile der Stützeinrichtung verstanden, die unmittelbar die Latten 18 oder andere Federelemente zur Abstützung der Polsterung tragen. Der äußere Rahmen 6 stellt somit kein Stützteil im Sinne der Erfindung dar.The support members 4, 8, 10, 12, 14, 16 carry on its upper side spring elements, which are formed in this embodiment by resilient slats, of which in the drawing only a bar is provided with the reference numeral 18. Under support members according to the invention those parts of the support means understood that directly carry the slats 18 or other spring elements for supporting the padding. The outer frame 6 thus does not constitute a support member according to the invention.

Die Stützteile 4, 8, 10, 12, 14, 16 sind in Fig. 1 in einer ersten Endlage der Verstellbewegung dargestellt, die eine Sitzposition der Stützeinrichtung 2 bildet. In einer anderen in der Zeichnung nicht dargestellten Endlage der Verstellbewegung spannen die Stützteile 4, 8, 10, 12, 14, 16 eine im wesentlichen ebene Fläche zur flächigen Abstützung der in der Zeichnung nicht dargestellten Polsterung auf.The support members 4, 8, 10, 12, 14, 16 are shown in Fig. 1 in a first end position of the adjusting movement, which forms a seating position of the support means 2. In another in the drawing, not shown end position of the adjustment tension the support members 4, 8, 10, 12, 14, 16 a substantially flat surface for planar support of the padding, not shown in the drawing.

Fig. 2 zeigt eine Perspektivansicht von unten der Stützeinrichtung gemäß Fig. 2. Das mittlere Stützteil 4 weist einen in Längsrichtung der Stützeinrichtung 2 verlaufenden ersten Längsholm 20 und einen in Längsrichtung der Stützeinrichtung 2 verlaufenden zweiten Längsholm 22 auf. Die Längsholme 20, 22 sind bei diesem Ausführungsbeispiel zur Aufnahme von Teilen der Antriebsmittel als Hohlprofile ausgebildet und verlaufen im wesentlichen parallel zueinander.2 shows a perspective view from below of the support device according to FIG. 2. The middle support part 4 has a first longitudinal spar 20 extending in the longitudinal direction of the support means 2 and a second longitudinal spar 22 extending in the longitudinal direction of the support means 2. The longitudinal beams 20, 22 are formed in this embodiment for receiving parts of the drive means as hollow profiles and extend substantially parallel to each other.

Erfindungsgemäß ist ein Antriebsmotor 24 außerhalb des ersten Längsholmes 20 an einer dem zweiten Längsholm 22 gegenüberliegenden seitlichen Wandung 26 des ersten Längsholmes 20 angeordnet und befestigt. Aus Fig. 2 ist nicht ersichtlich und deshalb wird hier erläutert, daß in der seitlichen Wandung 26 eine Ausnehmung gebildet ist, durch die sich bei diesem Ausführungsbeispiel ein mit der Abtriebswelle des Antriebsmotors 24 in Drehantriebsverbindung stehendes erstes Getriebeelement in das Innere des ersten Längsholmes 20 erstreckt und mit einem im Inneren des ersten Längsholmes 20 angeordneten zweiten Getriebeelement in Eingriff steht.According to the invention, a drive motor 24 is arranged outside the first longitudinal spar 20 on a side wall 26 of the first longitudinal spar 20 opposite the second longitudinal spar 22 and fastened. Out Fig. 2 is not apparent and therefore it is explained here that in the lateral wall 26, a recess is formed through which extends in this embodiment, standing with the output shaft of the drive motor 24 in rotary drive connection first transmission element in the interior of the first longitudinal spar 20 and with a arranged in the interior of the first longitudinal spar 20 second transmission element is engaged.

Fig. 3 zeigt eine Seitenansicht des ersten Längsholmes 20, wobei aus Gründen der Darstellung eine Hälfte des ersten Längsholmes 20 weggelassen ist. Wie aus Fig. 3 ersichtlich, ist der erste Längsholm 20 als Hohlprofil ausgebildet, wobei bei diesem Ausführungsbeispiel mit Ausnahme des Antriebsmotors 24 sämtliche Bauteile der Antriebsmittel in dem hohlen Inneren des ersten Längsholmes 20 aufgenommen sind. Im einzelnen weisen die Antriebsmittel bei diesem Ausführungsbeispiel ein Schneckengetriebe auf, dessen Schnecke 28 an die Abtriebswelle des Antriebsmotors 24 angeformt ist und in das Innere des ersten Längsholmes 20 hineinragt und mit einem im Inneren des Längsholmes 20 drehbar gelagerten Schneckenrad 30 in Eingriff steht. Das Schneckenrad 30 ist drehfest mit einer drehbar im Inneren des ersten Längsholmes 20 gelagerten Gewindespindel 32 verbunden, auf der eine in Axialrichtung der Gewindespindel 32 in Richtung eines Doppelpfeiles 34 bewegliche Spindelmutter 36 angeordnet ist, die verdrehsicher gelagert ist und ein linear bewegliches Antriebselement der Antriebsmittel bildet. Mit der Spindelmutter 36 ist zugfest ein Ende einer Kette 38 verbunden, deren anderes Ende mit einem Kettensegment 40 in Eingriff steht und an diesem festgelegt ist. Das Kettensegment 40 ist drehfest mit einer drehbar an dem ersten Längsholm 20 sowie dem zweiten Längsholm 22 gelagerten Welle 42 verbunden, mit der drehfest ein Verstellhebel 44 verbunden ist, der zum Verschwenken des Lordosenstützteiles 8, des Oberkörperstützteiles 10 und des Kopfstützteiles 12 dient.Fig. 3 shows a side view of the first longitudinal spar 20, wherein for the sake of illustration one half of the first longitudinal spar 20 is omitted. As can be seen from FIG. 3, the first longitudinal spar 20 is designed as a hollow profile, with all components of the drive means being accommodated in the hollow interior of the first longitudinal spar 20 in this exemplary embodiment, with the exception of the drive motor 24. In detail, the drive means in this embodiment, a worm gear, the worm 28 is integrally formed on the output shaft of the drive motor 24 and projects into the interior of the first longitudinal spar 20 and with a rotatably mounted inside the longitudinal spar 20 worm wheel 30 is engaged. The worm wheel 30 is rotatably connected to a rotatably mounted in the interior of the first longitudinal spar 20 threaded spindle 32 on which an axially movable screw 32 in the direction of a double arrow 34 movable spindle nut 36 is mounted, which is mounted against rotation and forms a linearly movable drive element of the drive means , With the spindle nut 36, one end of a chain 38 is connected, the other end of which is engaged with a chain segment 40 and fixed thereto. The chain segment 40 is rotatable with a rotatable on the first longitudinal beam 20 and the second longitudinal beam 22 mounted shaft 42 is connected to the rotationally fixed an adjusting lever 44, which serves for pivoting the lumbar support member 8, the upper body support member 10 and the head support member 12.

Zum Verschwenken des Lordosenstützteiles 8, des Oberkörperstützteiles 10 und des Kopfstützteiles 12 relativ zu dem mittleren Stützteil 4 treibt der Antriebsmotor 24 die Gewindespindel 32 derart an, daß sich die Spindelmutter 36 in Fig. 3 nach rechts schraubt. Aufgrund der über die Kette 38 zugfesten Verbindung der Spindelmutter 36 mit dem Kettensegment 40 verschwenkt hierbei das Kettensegment 40 in Fig. 3 im Uhrzeigersinn, wodurch die Welle 42 und der Verstellhebel 44 ebenfalls in Fig. 3 im Uhrzeigersinn verschwenken und hierbei das Lordosenstützteil 8, das Oberkörperstützteil 10 und das Kopfstützteil 12 aus seiner Ausgangslage, in der diese Stützteile eine im wesentlichen ebene Fläche aufspannen, in die in Fig. 1 dargestellte Endlage der Verstellbewegung bewegen. Die Übertragung der Verschwenkbewegung von dem Schwenkhebel 44 auf die Stützteile 8, 10, 12 erfolgt in dem Fachmann bekannter Weise, so daß die zugehörigen Bauteile hier nicht näher erläutert werden.For pivoting the Lordosenstützteiles 8, the upper body support member 10 and the head support member 12 relative to the central support member 4 drives the drive motor 24, the threaded spindle 32 in such a way that the spindle nut 36 screws in Fig. 3 to the right. Due to the over the chain 38 tensile connection of the spindle nut 36 with the chain segment 40 here pivots the chain segment 40 in Fig. 3 in a clockwise direction, whereby the shaft 42 and the lever 44 also pivot in Fig. 3 in a clockwise direction and in this case the lumbar support part 8, the Upper body support member 10 and the head support member 12 from its initial position in which these support parts span a substantially flat surface, move into the end position of the adjustment shown in Fig. 1. The transmission of the pivoting movement of the pivot lever 44 on the support members 8, 10, 12 takes place in the conventional manner, so that the associated components are not explained in detail here.

Bei dem Ausführungsbeispiel gemäß Fig. 1 sind in dem zweiten Längsholm 22 Antriebsmittel aufgenommen, denen ein Antriebsmotor 24' zugeordnet ist und die in hier nicht näher interessierender Weise zur Verstellung des Beinstützteiles 14 und des Wadenstützteiles 16 dienen.In the embodiment according to FIG. 1, drive means are accommodated in the second longitudinal beam 22, to which a drive motor 24 'is assigned and which serve to adjust the leg support part 14 and the calf support part 16 in a manner not of interest here.

Die Antriebskraft des Antriebsmotors 24 wird von der Seite des ersten Längsholmes 20 durch einen in der Zeichnung nicht näher dargestellten Übertragungsmechanismus auf die Seite des zweiten Längsholmes 22 übertragen, so daß die Antriebskraft des Antriebsmotors 24 bezüglich einer Längsmittelebene der Stützeinrichtung 2 im wesentlichen symmetrisch in das Lordosenstützteil 8, das Oberkörperstützteil 10 und das Kopfstützteil 12 eingeleitet wird. In hierzu entsprechender Weise wird die Antriebskraft des Antriebsmotors 24' durch einen in der Zeichnung nicht näher dargestellten Übertragungsmechanismus von der Seite des zweiten Stützteiles 22 auf die Seite des ersten Stützteiles 20 übertragen, so daß die Antriebskraft des Antriebsmotors 24' bezüglich einer Längsmittelebene der Stützeinrichtung 2 im wesentlichen symmetrisch in das Beinstützteil 14 und das Wadenstützteil 16 eingeleitet wird.The driving force of the drive motor 24 is transmitted from the side of the first longitudinal spar 20 by a transmission mechanism not shown in the drawing on the side of the second longitudinal spar 22, so that the driving force of the drive motor 24 with respect to a longitudinal center plane of the support means 2 is introduced substantially symmetrically in the Lordosenstützteil 8, the upper body support member 10 and the head support member 12. In a corresponding manner, the driving force of the drive motor 24 'is transmitted from the side of the second support member 22 to the side of the first support member 20 by a transmission mechanism, not shown in detail in the drawing, so that the drive force of the drive motor 24' with respect to a longitudinal center plane of the support device. 2 is introduced symmetrically into the leg support member 14 and the calf support member 16 substantially.

In Abwandlung dieser Ausführungsform ist es auch möglich, zur Verstellung der Stützteile 8, 10, 12 zwei Antriebsmotoren vorzusehen, von denen einer an dem ersten Längsholm 20 und der andere an dem zweiten Längsholm 22 angeordnet ist, wobei diese Antriebsmotoren dann synchron zueinander angesteuert werden. In hierzu entsprechender Weise ist es auch möglich, zur Verstellung des Beinstützteiles 14 und des Wadenstützteiles 16 zwei synchron zueinander angesteuerte Antriebsmotoren vorzusehen, von denen einer an dem ersten Längsholm 20 und der andere an dem zweiten Längsholm 22 angeordnet ist.In a modification of this embodiment, it is also possible to provide for the adjustment of the support members 8, 10, 12, two drive motors, one of which is arranged on the first longitudinal beam 20 and the other on the second longitudinal beam 22, said drive motors are then driven synchronously to each other. In a corresponding manner, it is also possible to provide for the adjustment of the leg support member 14 and the calf support member 16 two synchronously driven drive motors, one of which is arranged on the first longitudinal spar 20 and the other on the second longitudinal spar 22.

Wie aus Fig. 3 ersichtlich ist, liegt der Antriebsmotor 24 in der in Fig. 3 dargestellten Seitenansicht innerhalb der Profilhöhe H des ersten Längsholmes 20, derart, daß der Antriebsmotor 24 in Vertikalrichtung nicht über den ersten Längsholm 20 übersteht.3, the drive motor 24 is in the side view shown in FIG. 3 within the profile height H of the first longitudinal spar 20, such that the drive motor 24 does not project beyond the first longitudinal spar 20 in the vertical direction.

Auf diese Weise ergibt sich eine besonders geringe Bauhöhe der Stützeinrichtung 2.In this way, a particularly low overall height of the support device 2 results.

Wie aus Fig. 3 ferner ersichtlich ist, bildet die in Fig. 3 senkrecht aus der Zeichenebene heraus verlaufende Drehachse 46 der Schnecke 28 mit der in Fig. 3 durch eine strichpunktierte Linie 48 symbolisierten Drehachse 48 des Schneckenrades 30 einen Winkel von etwa 90°. Auf diese Weise ergibt sich ein besonders einfacher und kompakter Aufbau der durch das Schneckengetriebe 28, 30 gebildeten Getriebeanordnung.As can be seen from Fig. 3 also, forms the in Fig. 3 perpendicular to the drawing plane extending axis of rotation 46 of the screw 28 with the symbolized in Fig. 3 by a dashed line 48 axis of rotation 48 of the worm wheel 30 an angle of about 90 °. In this way, a particularly simple and compact construction of the gear arrangement formed by the worm gear 28, 30 results.

Da das mittlere Stützteil 4 ein ortsfestes Stützteil ist, das bei Verstellung der übrigen Stützteile 8, 10, 12, 14, 16 nicht bewegt wird, verbleibt der Antriebsmotor 24 stets ortsfest in seiner Position. Auf diese Weise ist der Aufbau weiter vereinfacht.Since the central support member 4 is a stationary support member, which is not moved upon adjustment of the remaining support members 8, 10, 12, 14, 16, the drive motor 24 always remains stationary in its position. In this way, the structure is further simplified.

Fig. 4 zeigt eine Ansicht von oben auf den ersten Längsholm 20, wobei aus Darstellungsgründen ein Teil des ersten Längsholmes 20 weggelassen ist. Es ist ersichtlich, daß der Antriebsmotor 24 an einer dem in Fig. 4 nicht erkennbaren zweiten Längsholm 22 des mittleren Stützteiles 4 zugewandten seitlichen Wandung 26 des ersten Längsholmes 20 angeordnet ist. Die Befestigung kann auf beliebige geeignete Weise erfolgen. Insbesondere kann der Antriebsmotor 24 lösbar an dem ersten Längsholm 20 befestigt sein. Es ist insbesondere möglich, den Antriebsmotor 24 an einer insbesondere winkelartig ausgebildeten Halterung anzuordnen, die in das Innere des ersten Längsholmes 20 eingreift und durch beliebige geeignete Mittel insbesondere formschlüssig in dem Inneren des ersten Längsholmes 20 festgelegt ist.Fig. 4 shows a view from above of the first longitudinal spar 20, wherein for reasons of illustration, a part of the first longitudinal spar 20 is omitted. It can be seen that the drive motor 24 is disposed on a side wall 26, not visible in FIG. 4, of the middle support member 4, of the first longitudinal member 20. The attachment can be done in any suitable manner. In particular, the drive motor 24 may be detachably attached to the first longitudinal spar 20. In particular, it is possible to arrange the drive motor 24 on a bracket, which is designed in particular as an angle, which engages in the interior of the first longitudinal spar 20 and is fixed by any suitable means, in particular in a form-fitting manner in the interior of the first longitudinal spar 20.

Es ist aus Fig. 4 ferner ersichtlich, daß die in Fig. 4 durch eine strichpunktierte Linie 46 symbolisierte Drehachse der an die Abtriebswelle des Antriebsmotors 24 angeformten Schnecke 28 mit der in Fig. 4 durch eine strichpunktierte Linie 50 symbolisierten Längsachse des ersten Längsholmes 20, die bei diesem Ausführungsbeispiel mit der linearen Verstellachse der Spindelmutter 34 zusammenfällt, einen Winkel von etwa 90° bildet.4 that the symbolized in Fig. 4 by a dashed line 46 axis of rotation of the integrally formed on the output shaft of the drive motor 24 screw 28 with the symbolized in Fig. 4 by a dashed line 50 longitudinal axis of the first longitudinal spar 20, the at this Embodiment coincides with the linear adjustment axis of the spindle nut 34 forms an angle of about 90 °.

Fig. 5 entspricht der Ansicht von oben gemäß Fig. 4, wobei ein in Fig. 4 weggelassener Teil des Längsholmes 20 dargestellt ist.Fig. 5 corresponds to the top view of FIG. 4, wherein a omitted in Fig. 4 part of the longitudinal spar 20 is shown.

Aus Fig. 6, die einen Schnitt entlang einer Linie VI-VI in Fig. 5 zeigt, ist ersichtlich, daß ein Gehäuse 52 des Antriebsmotors 24 im wesentlichen vollständig außerhalb des hohlen Inneren 54 des ersten Längsholmes 20 angeordnet ist, während die Abtriebswelle des Antriebsmotors 24 und die an die Abtriebswelle angeformte Schnecke 28 durch die in Fig. 6 mit dem Bezugszeichen 56 versehene Ausnehmung in der seitlichen Wandung 26 des ersten Längsholmes 20 in das Innere des ersten Längsholmes 20 hineinragt und mit dem im Inneren des ersten Längsholmes 20 angeordneten Schneckenrad 30 in Eingriff steht.From Fig. 6, which shows a section along a line VI-VI in Fig. 5, it can be seen that a housing 52 of the drive motor 24 is disposed substantially entirely outside the hollow interior 54 of the first longitudinal spar 20, while the output shaft of the drive motor 24 and the integrally formed on the output shaft screw 28 projects through the recess provided in Fig. 6 with the reference numeral 56 in the lateral wall 26 of the first longitudinal spar 20 in the interior of the first longitudinal spar 20 and with the arranged inside the first longitudinal spar 20 worm wheel 30th engaged.

In Fig. 7 ist ein zweites Ausführungsbeispiel einer erfindungsgemäßen Stützeinrichtung dargestellt, das sich von dem Ausführungsbeispiel gemäß Fig. 1 dadurch unterscheidet, daß der Antriebsmotor 24 in einer kastenartigen Verkleidung 58 aufgenommen ist, die bei diesem Ausführungsbeispiel lösbar mit dem ersten Längsholm 20 verbunden ist.In Fig. 7, a second embodiment of a support device according to the invention is shown, which differs from the embodiment of FIG. 1 in that the drive motor 24 is received in a box-like casing 58, which is detachably connected to the first longitudinal spar 20 in this embodiment.

Fig. 8 zeigt einen Schnitt entlang einer Linie VIII-VIII in Fig. 7.Fig. 8 shows a section along a line VIII-VIII in Fig. 7.

Die erfindungsgemäße Stützeinrichtung weist einen besonders kompakten und raumsparenden Aufbau auf, da der Antriebsmotor 24 einerseits innerhalb der Profilhöhe des ersten Längsholmes 20 liegt und somit nicht über den ersten Längsholm 20 übersteht und andererseits zwischen den sich gegenüberliegenden seitlichen Wandungen des ersten Längsholmes 20 und des zweiten Längsholmes 22 aufgenommen ist. Darüber hinaus ist die erfindungsgemäße Einrichtung 2 besonders einfach im Aufbau und damit besonders kostengünstig herstellbar, insbesondere aufgrund der Verwendung eines einfachen Schneckengetriebes zur Übertragung des Antriebsdrehmomentes des Antriebsmotors 24 auf die zu verstellenden Stützteile.The support device according to the invention has a particularly compact and space-saving design, since the drive motor 24 on the one hand within the profile height of the first longitudinal spar 20 and thus does not project beyond the first longitudinal spar 20 and on the other hand between the opposite lateral walls of the first longitudinal spar 20 and the second longitudinal spar 22 is included. In addition, the device 2 according to the invention is particularly simple in construction and thus particularly inexpensive to produce, in particular due to the use of a simple worm gear for transmitting the drive torque of the drive motor 24 to be adjusted to support parts.
