Entsprechend den jeweiligen Anforderungen können hierbei die Betätigungselemente auf Zug oder auf Druck beanspruchbar sein.An advantageous development of the invention provides that the actuating elements are each rod-shaped. In this way, stitching results in a particularly simple and cost-effective construction. According to the respective requirements in this case the actuators can be claimed on train or on pressure.

Eine außerordentlich vorteilhafte Weiterbildung der Erfindung sieht vor, daß wenigstens ein Stützteil entfernt von der Führung eines an dem Stützteil geführten Betätigungselementes eine Anlagefläche aufweist, wobei in einer ersten kinematischen Phase das Verstellelement oder ein an einem benachbarten Stützteil angeordnetes Betätigungselement mit einer Wirkfläche an dem Betätigungselement zur Anlage gelangt und dieses linear verschiebt und wobei in einer zweiten kinematischen Phase das Verstellelement oder das an dem benachbarten Stützteil angeordnete Betätigungselement mit seiner Wirkfläche an der Anlagefläche des Stützteiles exzentrisch zu dessen Schwenkachse zur Anlage gelangt und das Stützteil um die Schwenkachse verschwenkt. Bei dieser Ausführungsform können mittels eines besonders einfachen Aufbaus beispielsweise ein Kopfstützteil und ein Oberkörperstützteil relativ zu einem ortsfesten Stützteil verstellt werden. In der ersten kinematischen Phase verschiebt das Verstellelement, beispielsweise ein Schieber eines an dem ortsfesten Stützteil angeordneten Spindeltriebes, einen an dem Oberkörperstützteil geführtes Betätigungselement linear. Das Betätigungselement greift exzentrisch zu der zugeordneten Schwenkachse an dem Kopfstützteil an, so daß dieses beim linearen Verschieben des Stößels verschwenkt wird. Sobald der Schieber an der Anlagefläche des Oberkörperstützteiles zur Anlage gelangt, wird das Betätigungselement nicht weiter linear verschoben, so daß das Kopfstützteil nicht weiter verschwenkt wird. Stattdessen drückt der Schieber in der zweiten kinematischen Phase exzentrisch zu der zugeordneten Drehachse gegen das Oberkörperstützteil, so daß dieses - zusammen mit dem bereits verschwenkten Kopfstützteil - verschwenkt wird. Die entsprechende Kinematik der Stützteile ist damit durch nur wenige Bauteile realisiert.An extraordinarily advantageous development of the invention provides that at least one support member remote from the guidance of a guided on the support member actuating element has a contact surface, wherein in a first kinematic phase, the adjusting element or arranged on an adjacent support member actuating element with an active surface on the actuating element for Arrives system and this moves linearly and wherein in a second kinematic phase, the adjusting element or disposed on the adjacent support member actuator comes with its active surface on the contact surface of the support member eccentrically to the pivot axis to the plant and pivots the support member about the pivot axis. In this embodiment, by means of a particularly simple construction, for example, a headrest part and an upper body support part can be fixed relative to a stationary one Support part to be adjusted. In the first kinematic phase, the adjusting element, for example a slider of a spindle drive arranged on the stationary support part, displaces linearly an actuating element guided on the upper body support part. The actuator engages eccentrically to the associated pivot axis of the head support member so that it is pivoted during linear displacement of the plunger. As soon as the slider comes to rest on the contact surface of the upper body support member, the actuator is not further linearly displaced, so that the headrest part is not pivoted further. Instead, the slider presses in the second kinematic phase eccentrically to the associated axis of rotation against the upper body support member, so that this - together with the already pivoted headrest part - is pivoted. The corresponding kinematics of the support parts is thus realized by only a few components.

Eine andere außerordentlich vorteilhafte Weiterbildung der Erfindung sieht vor, daß das Verstellelement wenigstens ein Betätigungselement und/oder wenigstens ein Betätigungselement ein benachbartes Betätigungselement und/oder wenigstens ein Betätigungselement das zugeordnete Stützteil lose beaufschlagt. Diese Ausführungsform ist besonders dann vorteilhaft, wenn die kraftübertragenden Bauteile in dem Antriebsstrang der Stützeinrichtung während des Verschwenkens eines Stützteiles oder mehrerer Stützteile auf Druck beansprucht sind. Falls die kraftübertragenden Bauteile oder wenigstens eines dieser Bauteile während des Verschwenkens eines Stützteiles auf Zug beansprucht ist, kann jedoch das Verstellelement mit einem Betätigungselement bzw. ein Betätigungselement mit einem benachbarten Betätigungselement bzw. ein Betätigungselement mit dem zugeordneten Stützteil fest verbunden sein.Another extremely advantageous development of the invention provides that the adjusting element at least one actuating element and / or at least one actuating element an adjacent actuating element and / or at least one actuating element, the associated support member loosely applied. This embodiment is particularly advantageous when the force-transmitting components are claimed in the drive train of the support device during the pivoting of a support member or several support members to pressure. If the force-transmitting components or at least one of these components is claimed during the pivoting of a support member to train, however, the adjusting element with an actuating element or an actuating element with an adjacent actuating element or an actuating element with the associated Support member to be firmly connected.

Das Verstellelement kann in beliebiger geeigneter Weise ausgebildet sein, vorzugsweise durch das Abtriebsorgan eines Linearantriebs. Insoweit sieht eine vorteilhafte Weiterbildung der Erfindung vor, daß das Verstellelement eine Spindelmutter ist oder mit einer Spindelmutter verbunden ist, die verdrehsicher und in Axialrichtung beweglich auf einer drehantreibbaren Gewindespindel angeordnet ist.

In that regard, an advantageous development of the invention, that the adjusting element is a spindle nut or is connected to a spindle nut which is arranged against rotation and movable in the axial direction on a rotatably driven threaded spindle. Such spindle drives are available as simple, cost-effective and robust standard components and are suitable for transmitting large forces.

Eine vorteilhafte Weiterbildung insbesondere der Ausführungsform, bei der wenigstens ein Betätigungselement während des Verschwenkens des zugehörigen Stützteils auf Druck beansprucht ist, sieht vor, daß das Verstellelement als Schieber ausgebildet ist. In Kombination mit der vorgenannten Ausführungsform kann der Schieber durch die Spindelmutter gebildet oder mit der Spindelmutter verbunden sein.An advantageous development, in particular of the embodiment in which at least one actuating element is claimed during the pivoting of the associated support member to pressure, provides that the adjusting element is designed as a slide. In combination with the aforementioned embodiment, the slider may be formed by the spindle nut or connected to the spindle nut.

Gemäß einer anderen vorteilhaften Weiterbildung wirken die Betätigungselemente derart mit dem Antrieb zusammen, daß die Stützteile zeitlich aufeinanderfolgend verschwenken.According to another advantageous development, the actuating elements cooperate with the drive in such a way that the support parts pivot in chronological succession.

Eine andere außerordentlich vorteilhafte Weiterbildung der Erfindung sieht vor, daß die Länge der Betätigungselemente und jeweils der Abstand der Wirkfläche eines Betätigungselements von der Anlagefläche des zugeordneten Stützteiles in einer unverstellten Position der Stützteile so bemessen sind, daß die Stützteile zeitlich aufeinanderfolgend verschwenken. Auf diese Weise ist eine besonders ergonomische Verstellung realisierbar, bei der beispielsweise zuerst ein Kopfstützteil und daran anschließend ein Oberkörperstützteil eines Lattenrostes verschwenkt. Die Anzahl der Stützteile ist bei sämtlichen Ausführungsformen einer erfindungsgemäßen Stützeinrichtung innerhalb weiter Grenzen wählbar.Another extremely advantageous development of the invention provides that the length of the actuating elements and in each case the distance of the active surface of an actuating element of the contact surface of the associated support member in an unadjusted position of the support members are dimensioned so that the support members pivot in chronological succession. In this way, a particularly ergonomic adjustment can be realized in which pivoted first, for example, a headrest part and then an upper body support part of a slatted frame. The number of support members is selectable within wide limits in all embodiments of a support device according to the invention.

Im Sinne eines einfachen und kostengünstigen Aufbaus unter Verwendung möglichst weniger unterschiedlicher Bauteile sieht eine andere vorteilhafte Weiterbildung vor, daß die Betätigungselemente im wesentlichen die gleiche Länge aufweisen.In terms of a simple and inexpensive construction using as few different components as possible, another advantageous development provides that the actuating elements have substantially the same length.

Eine andere Weiterbildung der Erfindung sieht vor, daß in einer unverstellten Position der Abstand der Wirkfläche eines Betätigungselementes von der Anlagefläche des zugeordneten Stützteiles von dem dem Verstellelement am nächsten liegenden Betätigungselement zu dem dem Verstellelement am entferntesten liegenden Betätigungselement abnimmt. Bei im wesentlichen gleicher Länge der Betätigungselemente ergibt sich bei dieser Ausführungsform eine Kinematik, bei der das dem Verstellelement und damit dem Antrieb am entferntesten liegende Stützteil als erstes verschwenken und daran anschließend nacheinander die dem Antrieb näher liegenden Stützteile verschwenken.Another embodiment of the invention provides that in an unadjusted position, the distance of the active surface of an actuating element of the contact surface of the associated support member decreases from the adjusting element nearest the actuating element to the adjustment element furthest lying actuator. At substantially the same length of the actuators results in this embodiment, a kinematics in which the adjustment element and thus the drive farthest support member pivot first and then successively pivot the drive closer to the support parts.

Das in der Zeichnung dargestellte Ausführungsbeispiel der erfindungsgemäßen Stützeinrichtung ist als Lattenrost ausgeführt, wobei aus Gründen der Übersichtlichkeit halber jeweils ausschließlich der Grundkörper des Lattenrostes ohne Latten dargestellt ist.The illustrated in the drawing embodiment of the support device according to the invention is designed as a slatted frame, for reasons of clarity, only the main body of the slatted base without slats is shown in each case.

In Fig. 1 ist in teilweise geschnittener Seitenansicht ein Ausführungsbeispiel einer erfindungsgemäßen Stützeinrichtung 2 in Form eines Lattenrostes dargestellt, die ein erstes Stützteil 4 aufweist, das bei diesem Ausführungsbeispiel durch ein ortsfestes Stützteil gebildet ist. Die Stützeinrichtung 4 weist ferner ein zweites Stützteil 6 auf. In Längsrichtung der Stützeinrichtung 2 ist zwischen dem ersten Stützteil 4 und dem zweiten Stützteil 6 ein drittes Stützteil 8 angeordnet. In Fig. 1 ist lediglich ein zur Unterstützung des Oberkörper- bzw. Kopfstützteiles 8 bzw. 6 vorgesehener Teil der Stützeinrichtung 2 dargestellt. Ein zur Unterstützung des Waden- bzw. Beinbereiches vorgesehener Teil der Stützeinrichtung 2 ist entsprechend aufgebaut und wird daher hier nicht näher erläutert.In Fig. 1 is shown in a partially sectioned side view of an embodiment of a support device 2 according to the invention in the form of a slatted base, which has a first support member 4, which is formed in this embodiment by a stationary support member. The support device 4 also has a second support part 6. In the longitudinal direction of the support means 2, a third support part 8 is arranged between the first support part 4 and the second support part 6. In Fig. 1 only one part of the support device 2 provided for supporting the upper body or head support part 8 or 6 is shown. One to support the calf or leg area provided part of the support means 2 is constructed accordingly and will therefore not be explained here.

Das zweite Stützteil 6 ist gelenkig und um eine horizontale Schwenkachse 10, die in Fig. 1 in die Zeichenebene hinein verläuft, verschwenkbar mit dem dritten Stützteil 8 verbunden, das seinerseits gelenkig und um eine horizontale Schwenkachse 12, die in Fig. 1 in die Zeichenebene hinein verläuft, verschwenkbar mit dem ersten Stützteil 4 verbunden. Zum Verschwenken des zweiten Stützteiles 6 und des dritten Stützteiles 8 relativ zueinander und zu dem ersten Stützteil 4 ist ein elektromotorischer Antrieb 14 vorgesehen, der nachfolgend näher erläutert wird.The second support part 6 is articulated and about a horizontal pivot axis 10 which in Fig. 1 extends in the plane of the drawing, pivotally connected to the third support member 8, which in turn is articulated and about a horizontal pivot axis 12, the in Fig. 1 extends into the plane of the drawing, pivotally connected to the first support member 4. For pivoting the second support member 6 and the third support member 8 relative to each other and to the first support member 4, an electric motor drive 14 is provided, which will be explained in more detail below.

Der elektromotorische Antrieb 14 weist ein Verstellelement auf, das bei diesem Ausführungsbeispiel als Schieber 16 ausgebildet ist, der in Richtung eines Doppelpfeiles 18 hin- und herbeweglich ist. Der Schieber 16 ist bei diesem Ausführungsbeispiel verschiebefest mit einer Spindelmutter 20 verbunden, die verdrehsicher und in Axialrichtung beweglich auf einer Gewindespindel 22 angeordnet ist, die über ein Schneckengetriebe 24 mit einem in Fig. 1 nicht erkennbaren Elektromotor in Drehantriebsverbindung steht. Entsprechend der Drehrichtung der Abtriebswelle des Elektromotors und damit der Gewindespindel 22 bewegt sich die Spindelmutter 20 und damit der Schieber 16 in Fig. 1 nach rechts oder links.The electromotive drive 14 has an adjusting element, which is formed in this embodiment as a slide 16 which is reciprocable in the direction of a double arrow 18. In this exemplary embodiment, the slide 16 is connected so as to be non-slidably connected to a spindle nut 20, which is arranged so as to be non-rotatable and movable in the axial direction on a threaded spindle 22, which has a worm gear 24 with a spindle nut Fig. 1 unrecognizable electric motor is in rotary drive connection. According to the direction of rotation of the output shaft of the electric motor and thus the threaded spindle 22, the spindle nut 20 and thus the slider 16 moves in Fig. 1 to the right or left.

Der Schieber 16 steht über ein Betätigungselement 26 mit dem zweiten Stützteil 6 zum Verschwenken desselben in Kraftübertragungsverbindung. Bei dieser Ausführungsform ist das Betätigungselement 26 stangenartig ausgebildet und mittels des Schiebers 16 linear verschiebbar in einer Führung geführt, die in dem dritten Stützteil 8 gebildet ist. Bei dem dargestellten Ausführungsbeispiel beaufschlagt der Schieber 16 das dem zweiten Stützteil 6 abgewandte Ende des stangenartigen Betätigungselementes lose, wobei das Betätigungselement bei diesem Ausführungsbeispiel nach Art eines Stößels ausgebildet ist. Um unter Druckbelastung beim Verschwenken des zweiten Stützteiles 6 ein seitliches Ausknicken des Betätigungselementes 26 zu vermeiden, ist das Betätigungselement 26 in der Führung entweder auf seiner gesamten Länge eng geführt, oder es sind in Längsrichtung des Betätigungselementes 26 in kurzen Abständen Führungselemente vorgesehen, deren Abstand so gering gewählt ist, daß ein Ausknicken des Betätigungselements 26 vermieden ist. Die Führungselemente können beispielsweise steg- oder rippenartig ausgebildet sein.The slider 16 is connected via an actuating element 26 with the second support member 6 for pivoting the same in power transmission connection. In this embodiment, the actuating element 26 is rod-like and guided linearly displaceable by means of the slider 16 in a guide which in the third Support member 8 is formed. In the illustrated embodiment, the slider 16 acts on the second support member 6 remote from the end of the rod-like actuating element loosely, wherein the actuating element is formed in this embodiment in the manner of a plunger. In order to avoid a lateral buckling of the actuating element 26 under pressure load when pivoting the second support member 6, the actuating element 26 is guided in the guide either over its entire length, or guide elements are provided at short intervals in the longitudinal direction of the actuating element 26, the distance thereof is chosen low, that a buckling of the actuating element 26 is avoided. The guide elements may be formed web-like or rib-like, for example.

Wie aus Fig. 1 ersichtlich ist, greift das stangenartige Betätigungselement 26 zum Verschwenken des zweiten Stützteiles 6 exzentrisch zu der Schwenkachse 10 an dem zweiten Stützteil 6 an.How out Fig. 1 it can be seen, engages the rod-like actuator 26 for pivoting the second support member 6 eccentrically to the pivot axis 10 on the second support member 6 at.

Nachfolgend wird anhand der Fig. 2A bis 2D das zugrundeliegende Verstellprinzip näher erläutert. Die Fig. 2A bis 2C dienen ausschließlich zur Verdeutlichung des zugrundeliegenden Verstellprinzips, so daß die Stützteile 4, 6, 8 stark schematisiert und nicht maßstäblich dargestellt sind.The following is based on the Fig. 2A to 2D explained in more detail the underlying adjustment principle. The Fig. 2A to 2C serve only to illustrate the underlying adjustment principle, so that the support members 4, 6, 8 are shown in a highly schematic and not to scale.

Fig. 2A zeigt die Stützteile 4, 6, 8 in einer Verstellage, in der die Stützteile 4, 6, 8 gemeinsam eine im wesentlichen horizontale Stützebene aufspannen. Diese Verstellage entspricht einer unverstellten Position der Stützeinrichtung 2. Fig. 2A shows the support members 4, 6, 8 in an adjustment position in which the support members 4, 6, 8 together span a substantially horizontal support plane. This adjustment corresponds to an unadjusted position of the support device. 2

Wie in Fig. 2A dargestellt, ist das Betätigungselement 26 an dem dritten Stützteil 8 in einer Führung 28, die durch eine durchgehende kanalartige Ausnehmung gebildet ist, in seiner Längsrichtung verschiebbar an dem dritten Stützteil 8 geführt. Entfernt von der Führung 28 weist bei diesem Ausführungsbeispiel das dritte Stützteil 8 an seiner dem Schieber 16 zugewandten Stirnfläche eine Anlagefläche 30 auf, mit der eine dem dritten Stützteil 8 zugewandte Wirkfläche 32 des Schiebers 16 in weiter unten anhand der Fig. 2B und 2C näher erläuterter Weise zusammenwirkt.As in Fig. 2A illustrated, the actuator 26 is slidably on the third support member 8 in a guide 28 which is formed by a continuous channel-like recess in its longitudinal direction guided the third support member 8. Removes from the guide 28, in this embodiment, the third support member 8 on its the slider 16 facing end face on a bearing surface 30, with the third support member 8 facing the effective surface 32 of the slider 16 in below using the Figs. 2B and 2C cooperates closer explained way.

In einer ersten kinematischen Phase drückt der Schieber 16 gegen das Betätigungselement 26, so daß dieses in Fig. 2A nach rechts verschoben wird. Da das dem Schieber 32 abgewandte Ende des Betätigungselementes 28 exzentrisch zu der Schwenkachse 10 an dem zweiten Stützteil 6 angreift, wird dabei das zweite Stützteil 6 entgegen dem Uhrzeigersinn verschwenkt.In a first kinematic phase, the slider 16 presses against the actuating element 26, so that this in Fig. 2A is moved to the right. Since the slider 32 remote from the end of the actuating element 28 acts eccentrically to the pivot axis 10 on the second support member 6, while the second support member 6 is pivoted counterclockwise.

Fig. 2B stellt das Ende der ersten kinematischen Phase dar, in der das zweite Stüzteil 6 relativ zu dem dritten Stützteil 8 maximal entgegen dem Uhrzeigersinn verschwenkt ist. Fig. 2B represents the end of the first kinematic phase in which the second Stüzteil 6 is pivoted relative to the third support member 8 maximum counterclockwise.

In einer zweiten kinematischen Phase gelangt die Wirkfläche 32 des Schiebers 16 an der Anlagefläche 30 des dritten Stützteiles 8 zur Anlage. Bei dem dargestellten Ausführungsbeispiel ist hierzu der Querschnitt des Schiebers 16 an seinem freien Ende, also im Bereich der Wirkfläche 32, zumindest in einer Dimension größer als die lichte Weite der Führung 28. Aufgrund dieser Ausgestaltung wird in der zweiten kinematischen Phase das Betätigungselement 26 relativ zu dem dritten Stützteil 8 nicht weiter verschoben. Vielmehr drückt in der zweiten kinematischen Phase der Schieber 16 exzentrisch zu der Schwenkachse 12 gegen das dritte Stützteil 8, so daß dieses entgegen dem Uhrzeigersinn verschwenkt, wie in Fig. 2C dargestellt.In a second kinematic phase, the active surface 32 of the slider 16 comes to the contact surface 30 of the third support member 8 to the plant. In the illustrated embodiment, this is the cross section of the slider 16 at its free end, ie in the region of the active surface 32, at least in one dimension larger than the clear width of the guide 28. Due to this configuration, the actuator 26 is in the second kinematic phase relative to the third support member 8 not moved further. Rather, in the second kinematic phase, the slider 16 presses eccentrically to the pivot axis 12 against the third support member 8, so that this pivots counterclockwise, as in Fig. 2C shown.

Auf diese Weise wird mittels des Betätigungselementes sowohl das zweite Stützteil 6 verschwenkt, nämlich in der ersten kinematischen Phase, als auch das dritte Stützteil 8, nämlich in der zweiten kinematischen Phase.In this way, both the second support member 6 is pivoted by means of the actuating element, namely in the first kinematic phase, as well as the third support part 8, namely in the second kinematic phase.

Wie aus den Figuren 2A bis 2C ersichtlich ist, beaufschlagt der Schieber 16 das Betätigungselement 26 sowie das Betätigungselement 26 das zweite Stützteil 6 lose.Like from the FIGS. 2A to 2C it can be seen, the slider 16 acts on the actuating element 26 and the actuating element 26, the second support member 6 loose.

Eine Rückstellung der Stützteile 6, 8 in die in Fig. 2A dargestellte Ausgangslage, die einer unverstellten Position der Stützeinrichtung 2 entspricht, erfolgt unter der Gewichtskraft der Stützteile 6, 8, jedoch bei eingeschaltetem Antrieb, wobei sich die Spindelmutter 20 und der Schieber 16 in Fig. 1 nach links bewegen.A provision of the support members 6, 8 in the in Fig. 2A shown starting position, which corresponds to an unadjusted position of the support means 2, under the weight of the support members 6, 8, but with the drive, wherein the spindle nut 20 and the slider 16 in Fig. 1 move to the left.

Fig. 3 zeigt die Stützeinrichtung 2 gemäß Fig. 1 in einer Perspektivansicht, wobei erkennbar ist, daß zusätzlich zu dem ersten Stützteil 4, dem zweiten Stützteil 6 und dem dritten Stützteil 8 ein viertes Stützteil 34, ein fünftes Stützteil 36, ein sechstes Stützteil 38 und ein siebtes Stützteil 40 vorgesehen sind. Jeweils benachbarte der Stützteile 4-8 und 34-40 sind gelenkig und jeweils um eine horizontale Schwenkachse 12 bzw. 10 bzw. 42 bzw. 44 bzw. 46 bzw. 48 verschwenkbar miteinander verbunden. Die Stützteile 8, 6 und 34-40 bilden bei dem dargestellten Ausführungsbeispiel einen ersten Stützabschnitt zur Abstützung einer auf der Stützeinrichtung 2 ruhenden Person im Oberkörper/Kopfbereich, während das ortsfeste erste Stützteil 4 einen dritten Stützabschnitt bildet. Mit der dem dritten Stützteil 8 abgewandten Seite des ersten Stützteiles 4 verbundene, in Fig. 3 nicht näher bezeichnete Stützteile bilden einen dritten Stützabschnitt zur Abstützunng einer auf der Stützeinrichtung 2 ruhenden Person im Waden/Beinbereich. Fig. 3 shows the support 2 according to Fig. 1 in a perspective view, it being understood that in addition to the first support member 4, the second support member 6 and the third support member 8, a fourth support member 34, a fifth support member 36, a sixth support member 38 and a seventh support member 40 are provided. Respective adjacent support members 4-8 and 34-40 are hinged and pivotally connected to each other about a horizontal pivot axis 12 and 10 or 42 or 44 or 46 and 48, respectively. The support members 8, 6 and 34-40 form in the illustrated embodiment, a first support portion for supporting a resting on the support means 2 person in the upper body / head area, while the stationary first support member 4 forms a third support portion. With the third support member 8 facing away from the side of the first support member 4 connected in Fig. 3 unspecified support parts form a third support portion for Abstützunng a resting on the support means 2 person calf / leg area.

Aus Fig. 1 ist ersichtlich, daß den weiteren Stützteilen 34, 36, 38, 40 jeweils ein weiteres nach Art eines Stößels ausgebildetes Betätigungselement 50 bzw. 52 bzw. 54 bzw. 56 zugeordnet ist. Bei dem dargestellten Ausführungsbeispiel sind die Stützteile 6, 34, 36, 38 hinsichtlich ihres Aufbaus und dem Zusammenwirken mit dem zugeordneten Betätigungselement so aufgebaut, wie dies oben anhand des dritten Stützteiles 8 beschrieben worden ist. Gleichermaßen sind die Betätigungselemente 50, 52, 54, 56 so aufgebaut, wie dies oben anhand des Betätigungselementes 26 beschrieben worden ist.Out Fig. 1 It can be seen that the further support members 34, 36, 38, 40 each have a further formed in the manner of a plunger actuator 50 or 52 or 54 or 56 is assigned. In the illustrated embodiment, the support members 6, 34, 36, 38 constructed in terms of their structure and the interaction with the associated actuator as described above with reference to the third support member 8. Similarly, the actuators 50, 52, 54, 56 are constructed as described above with reference to the actuator 26.

Wie aus Fig. 1 ferner ersichtlich ist, liegen in der in Fig. 1 dargestellten Verstellage, in der die Stützteile 8, 6, 34, 36, 38, 40 eine im wesentlichen horizontale Stützebene aufspannen und die einer unverstellten Position der Stützeinrichtung 2 entspricht, die Betätigungselemente 26, 50, 52, 54, 56 mit ihren Stirnflächen lose aneinander bzw. dem Schieber 16 bzw. dem Stützteil 40 an.How out Fig. 1 Furthermore, it is apparent in the in Fig. 1 shown adjusting position in which the support members 8, 6, 34, 36, 38, 40 span a substantially horizontal support plane and which corresponds to an unadjusted position of the support means 2, the actuators 26, 50, 52, 54, 56 with their end faces loose together or the slider 16 and the support member 40 at.

Die Fig. 4A bis 4F stellen verschiedene kinematische Phasen während der Verstellung der Stützeinrichtung 2 dar. Der Übersichtlichkeit halber sind in den Figuren 4A bis 4F im wesentlichen ausschließlich die Bezugszeichen der in Bezug genommenen Bauteile eingetragen. Zur Verstellung der Stützteile der Stützeinrichtung 2 wird die Gewindespindel 22 derart drehangetrieben, daß sich die Spindelmutter 20 und damit der Schieber 16 in Fig. 1 nach rechts bewegt. Hierbei verschiebt der Schieber 16 das Betätigungselement 26 in Fig. 1 nach rechts, so daß dieses die Betätigungselemente 50, 52, 54 und 56 ebenfalls in Fig. 1 nach rechts verschiebt. Hierbei ist zunächst die Wirkfläche der Betätigungselemente 26, 50, 52, 54 und des Schiebers 16 jeweils noch von der Anlagefläche des zugeordneten Stützteiles 8, 6, 34, 36, 38 entfernt (vgl. hierzu Fig. 2A), so daß die Stützteile 8, 6, 34, 36, 38 zunächst zueinander unverschwenkt bleiben, während das Stützteil 40 in Zeichnung entgegen dem Uhrzeigersinn verschwenkt wird, bis die in Fig. 4A dargestellte Verschwenklage erreicht ist.The Figs. 4A to 4F represent different kinematic phases during the adjustment of the support means 2. For the sake of clarity are in the FIGS. 4A to 4F essentially only the reference numbers of the components referred to registered. To adjust the support parts of the support means 2, the threaded spindle 22 is rotationally driven so that the spindle nut 20 and thus the slider 16 in Fig. 1 moved to the right. Here, the slider 16 moves the actuator 26 in Fig. 1 to the right, so that this the actuators 50, 52, 54 and 56 also in Fig. 1 moves to the right. Here, first, the active surface of the actuating elements 26, 50, 52, 54 and the slider sixteenth each still from the contact surface of the associated support member 8, 6, 34, 36, 38 away (see Fig. 2A ), so that the support members 8, 6, 34, 36, 38 initially remain unverschwenkt each other while the support member 40 is pivoted in the drawing counterclockwise until the in Fig. 4A shown Verschwenklage is reached.

In der in Fig. 4A dargestellten Position der Betätigungselemente gelangt die Wirkfläche des Betätigungselements 54 exzentrisch zu der Schwenkachse 46 an der Anlagefläche des zugeordneten sechsten Stützteiles 48 zur Anlage, so daß das sechste Stützteil 48 um die Schwenkachse 46 relativ zu dem fünften Stützteil 36 in Fig. 4A entgegen dem Uhrzeigersinn verschwenkt wird. Hierbei sind die Wirkflächen des Schiebers 16 und der Betätigungselemente 26, 50, 52 zunächst noch zu den Anlageflächen der zugeordneten Stützteile beabstandet, so daß die Stützteile 8, 6, 34, 36 zunächst nicht verschwenkt werden.In the in Fig. 4A illustrated position of the actuating elements, the active surface of the actuating element 54 comes eccentrically to the pivot axis 46 on the contact surface of the associated sixth support member 48 to the system, so that the sixth support member 48 about the pivot axis 46 relative to the fifth support member 36 in Fig. 4A is pivoted counterclockwise. Here, the active surfaces of the slider 16 and the actuating elements 26, 50, 52 are initially spaced even to the contact surfaces of the associated support members, so that the support members 8, 6, 34, 36 are not initially pivoted.

Fig. 4B stellt eine Verstellage dar, in der die Wirkfläche des Betätigungselementes 52 an der Anlagefläche des fünften Stützteiles 36 exzentrisch zu der Schwenkachse 44 zur Anlage gelangt, so daß das fünfte Stützteil 36 bei einer weiteren Bewegung des Schiebers in Fig. 4B nach rechts in Fig. 4B entgegen dem Uhrzeigersinn verschwenkt wird. Fig. 4B represents an adjustment in which the active surface of the actuating element 52 on the contact surface of the fifth support member 36 eccentrically to the pivot axis 44 abuts, so that the fifth support member 36 in a further movement of the slide in Fig. 4B to the right in Fig. 4B is pivoted counterclockwise.

Bei einer weiteren Bewegung des Schiebers 16 in Fig. 4B nach rechts gelangt die Wirkfläche des Betätigungselementes 50 an der Anlagefläche des zugeordneten vierten Stützteils 34 exzentrisch zu der Schwenkachse 42 zur Anlage, so daß das vierte Stützteil 34 um die Schwenkachse 42 in Fig. 4C entgegen dem Uhrzeigersinn verschwenkt wird.In a further movement of the slider 16 in Fig. 4B to the right, the active surface of the actuating element 50 comes to the contact surface of the associated fourth support member 34 eccentrically to the pivot axis 42 to the system, so that the fourth support member 34 about the pivot axis 42 in Fig. 4C is pivoted counterclockwise.

Bei einer weiteren Bewegung des Schiebers 16 nach rechts in Fig. 4C gelangt in der in Fig. 4D dargestellten Position die Wirkfläche des Betätigungselementes 26 an der Anlagefläche des zugeordneten zweiten Stützteiles 6 exzentrisch zur Schwenkachse 10 zur Anlage, so daß das zweite Stützteil 6 relativ zu dem dritten Stützteil 8 in Fig. 4D entgegen dem Uhrzeigersinn verschwenkt wird.Upon further movement of the slider 16 after right in Fig. 4C arrives in the Fig. 4D illustrated position, the effective area of the actuating element 26 on the contact surface of the associated second support member 6 eccentric to the pivot axis 10 to the system, so that the second support member 6 relative to the third support member 8 in Fig. 4D is pivoted counterclockwise.

Bei einer weiteren Bewegung des Schiebers 16 in Fig. 4D nach rechts gelangt in der in Fig. 4E dargestellten Position der Schieber 16 mit seiner Wirkfläche an der Anlagefläche des zugeordneten dritten Stützteiles 8 exzentrisch zu der Schwenkachse 12 zur Anlage, so daß das dritte Stützteil 8 relativ zu dem ersten Stützteil 4 in Fig. 4E entgegen dem Uhrzeigersinn verschwenkt.In a further movement of the slider 16 in Fig. 4D comes to the right in the in Fig. 4E illustrated position of the slider 16 with its active surface on the contact surface of the associated third support member 8 eccentric to the pivot axis 12 to the system, so that the third support member 8 relative to the first support member 4 in Fig. 4E pivoted counterclockwise.

Fig. 4F stellt die Endlage der Verstellbewegung dar, die einer maximal verstellten Position der Stützteile der Stützeinrichtung 2 entspricht. Fig. 4F represents the end position of the adjustment, which corresponds to a maximum adjusted position of the support parts of the support means 2.

Aus der vorangegangenen Beschreibung der Fig. 1 und 4A bis 4F ist ersichtlich, daß die Stützteile 40, 38, 36, 34, 6, 8, beginnend mit dem Stützteil 40, nacheinander verschwenkt werden. Hierbei verschiebt ein Betätigungselement, beispielsweise das Betätigungselement 54, zunächst das benachbarte Betätigungselement, beispielsweise das Betätigungselement 56, linear, bis es mit seiner Wirkfläche an der Anlagefläche des zugeordneten Stützteiles, beispielsweise des sechsten Stützteiles 38, zur Anlage gelangt. Bei einer weiteren Bewegung des Betätigungselementes 54 wird dann das sechste Stützteil 38 verschwenkt. Dies gilt in der beschriebenen Weise auch für die weiteren Betätigungselemente 56, 52, 50, 26 bzw. den Schieber 16.From the foregoing description of Fig. 1 and 4A to 4F It can be seen that the support members 40, 38, 36, 34, 6, 8, starting with the support member 40, are pivoted one after the other. In this case, an actuating element, for example the actuating element 54, initially displaces the adjacent actuating element, for example the actuating element 56, linearly, until it comes into contact with its active surface against the contact surface of the associated supporting part, for example the sixth supporting part 38. In a further movement of the actuating element 54, the sixth support member 38 is then pivoted. This also applies in the manner described for the further actuating elements 56, 52, 50, 26 or the slide 16.

Wie aus Fig 1 ersichtlich ist, sind bei dem dargestellten Ausführungsbeispiel die Betätigungselemente 26, 50, 52, 54, 56 im wesentlichen gleich lang ausgebildet. Wie ferner aus Fig. 1 ersichtlich ist, nimmt in der unverstellten Position der Stützeinrichtung 2 der Abstand der Wirkfläche eines Betätigungselementes zu der Anlagefläche des zugeordneten Stützteiles, beispielsweise der Abstand der Wirkfläche des Betätigungselementes 56 zu der Anlagefläche des zugeordneten Stützteiles 40, von dem Schieber 16 am nächsten liegenden Betätigungselement, also dem Betätigungselement 26, zu dem dem Schieber 16 am entferntesten liegenden Betätigungselement, nämlich dem Betätigungselement 56, ab. Die jeweils gewünschte Kinematik ist durch entsprechende Wahl der Längen der Betätigungselemente einstellbar.How out Fig. 1 it can be seen, in the illustrated embodiment, the actuating elements 26, 50, 52, 54, 56 formed substantially the same length. As further out Fig. 1 it can be seen, takes in the unadjusted position of the support means 2, the distance of the active surface of an actuating element to the contact surface of the associated support member, for example, the distance of the active surface of the actuating element 56 to the contact surface of the associated support member 40, of the slider 16 nearest actuator, ie the actuator 26, to which the slider 16 farthest actuator, namely the actuator 56, from. The particular desired kinematics is adjustable by appropriate choice of the lengths of the actuators.

In Abwandlung des Ausführungsbeispieles gemäß Fig. 1 ist es beispielsweise möglich, die Länge des Betätigungselementes 52 so zu vergrößern und die Länge des Betätigungselementes 54 gleichzeitig so zu verkleinern, daß gleichzeitig die Wirkfläche des Betätigungselementes 54 an der Anlagefläche des sechsten Stützteiles 36 und die Wirkfläche des Betätigungselementes 52 an der Anlagefläche des zugeordneten fünften Stützteil 36 zur Anlage gelangt. In diesem Fall wird das siebte Stützteil 40 relativ zu dem sechsten Stützteil 38 verschwenkt, während die Stützteile 36, 38 relativ zueinander nicht verschwenkt werden. Auf diese Weise kann die Kinematik der Stützteile an die jeweiligen Anforderungen angepaßt werden.In a modification of the embodiment according to Fig. 1 For example, it is possible to increase the length of the actuating element 52 and simultaneously reduce the length of the actuating element 54 so that at the same time the active surface of the actuating element 54 on the contact surface of the sixth support member 36 and the active surface of the actuating element 52 on the contact surface of the associated fifth Support member 36 comes to the plant. In this case, the seventh support member 40 is pivoted relative to the sixth support member 38, while the support members 36, 38 are not pivoted relative to each other. In this way, the kinematics of the support members can be adapted to the respective requirements.

Dadurch, daß erfindungsgemäß den Stützteilen 4 bis 8 und 34 bis 40 jeweils ein separates Betätigungselement zugeordnet ist, sind erfindungsgemäß wenigstens zwei Stützteile, bei dem dargestellten Ausführungsbeispiel sämtliche Stützteile, unabhängig voneinander verschwenkbar. Auf diese Weise ist die Form der durch die Stützteile gebildeten Stützfläche innerhalb weiter Grenzen an die ergonomischen Gegebenheiten anpaßbar.Characterized in that according to the invention the support members 4 to 8 and 34 to 40 each associated with a separate actuator, according to the invention at least two support members, in the illustrated embodiment, all support members, independently pivotable. In this way, the shape of the through Support parts formed supporting surface within wide limits to the ergonomic conditions adaptable.
