Bei Verwendung eines Linearantriebs als Schwenkantrieb kann die Umsetzung der Linearbewegung des Abtriebsorganes des Linearantriebs in eine Schwenkbewegung auf vielfältige Weise realisiert werden. Eine besonders einfach aufgebaute Ausführungsform sieht insoweit vor, dass ein erstes Ende einer Verbindungslasche an einem ersten Gelenkpunkt gelenkig mit einem linear beweglichen Abtriebsorgan des zweiten Linearantriebs verbunden ist, während ein zweites Ende der Verbindungslasche an einem zweiten Gelenkpunkt mit der Schwenkwelle exzentrisch zu deren Schwenkachse verbunden ist, derart, dass die Schwenkwelle bei einer Linearbewegung des Abtriebsorgans um ihre Schwenkachse verschwenkt.When using a linear drive as a pivoting drive, the conversion of the linear movement of the driven element of the linear drive into a pivoting movement can be realized in many different ways.

Entlastung zu erzielen, sieht eine vorteilhafte Weiterbildung vor, dass wenigstens zwei Be-/Entlastungseinrichtungen vorgesehen sind, die in Längsrichtung der Stützeinrichtung zueinander beabstandet sind zum Beaufschlagen unterschiedlicher Bereiche in Längsrichtung der Stützeinrichtung. Auf diese Weise ist der Komfort für einen Benutzer der Stützeinrichtung weiter erhöht, indem beispielsweise gleichzeitig in unterschiedlichen Bereichen der Stützeinrichtung eine Massagewirkung erzielt werden kann.According to the invention, it is basically sufficient if the support device has a single loading/unloading device.

Dementsprechend haben die Arme 33, 33' die Funktion von Schwenkhebeln.A pivot shaft 46 is pivotably mounted on the first carriage 28 (cf. 6 ), with which the arms 33, 33' are connected in a rotationally fixed manner. The adjustment drive 38 is designed to pivot the pivot shaft 46 about its pivot axis in order to adjust the pressure elements 36, 36' relative to the slats 22, 24 by pivoting the arms 33, 33'. Accordingly, the arms 33, 33' have the function of pivoting levers.

Um den ersten Schlitten 28 entlang der ersten Linearführung 44 zu bewegen, weist der erste Linearantrieb einen ersten Spindeltrieb 48 (vgl. Fig. 6) auf. Der erste Spindeltrieb 48 weist eine erste Gewindespindel auf, die sich in Längsrichtung der ersten Linearführung 44 erstreckt und verdrehsicher gelagert ist. Eine erste Spindelmutter ist auf die erste Gewindespindel aufgesetzt und steht über ein Schneckengetriebe in Drehantriebsverbindung mit der Abtriebswelle des ersten Elektromotors 34. Die erste Spindelmutter ist zusammen mit dem Schneckengetriebe und der Abtriebswelle in dem ersten Schlitten 28 aufgenommen, der gehäuseartig ausgebildet ist.In order to move the first carriage 28 along the first linear guide 44, the first linear drive has a first spindle drive 48 (cf. 6 ) on. The first spindle drive 48 has a first threaded spindle, which extends in the longitudinal direction of the first linear guide 44 and is mounted in a torsion-proof manner. A first spindle nut is placed on the first threaded spindle and is in rotary drive connection with the output shaft of the first electric motor 34 via a worm gear. The first spindle nut is accommodated together with the worm gear and the output shaft in the first carriage 28, which is designed like a housing.

Bei Drehung der Abtriebswelle des ersten Elektromotors 34 dreht sich die erste Spindelmutter. Demzufolge bewegt sich der erste Schlitten 28 entlang der ersten Linearführung 44 in der einen oder anderen Richtung entsprechend dem Drehsinn der Spindelmutter, wodurch der erste Schlitten 28 mit den Druckelementen 36, 36' in Längsrichtung der ersten Linearführung positioniert wird, damit an der entsprechenden Stelle Latten 22, 24 durch die Druckelemente 36, 36' beaufschlagt werden zum Be-/Entlasten der betreffenden Latten 22, 24.When the output shaft of the first electric motor 34 rotates, the first spindle nut rotates. As a result, the first carriage 28 moves along the first linear guide 44 in one direction or the other according to the direction of rotation of the spindle nut, as a result of which the first carriage 28 with the pressure elements 36, 36' is positioned in the longitudinal direction of the first linear guide, so that slats are positioned at the corresponding point 22, 24 are acted upon by the pressure elements 36, 36' to load/unload the relevant slats 22, 24.

Parallel zu der ersten Linearführung 44 verlaufend ist eine zweite Linearführung 50 (vgl. Fig. 5) vorgesehen. An der zweiten Linearführung 50 ist ein zweiter Schlitten 52 in Längsrichtung der Stützeinrichtung 2 geführt.Running parallel to the first linear guide 44 is a second linear guide 50 (cf. figure 5 ) intended. A second carriage 52 is guided on the second linear guide 50 in the longitudinal direction of the support device 2 .

Die Schwenkwelle 46 ist drehbar bzw. schwenkbar mit dem zweiten Schlitten 52 verbunden. Der zweite Schlitten 52 ist somit mittels der Schwenkwelle verschiebefest mit dem ersten Schlitten 28 verbunden. Dementsprechend bewegen sich die Schlitten 28, 52 synchron, wenn sich der erste Schlitten 28 bei Betätigung des ersten Elektromotors 34 bewegt.The pivot shaft 46 is pivotally connected to the second carriage 52 . The second carriage 52 is thus connected to the first carriage 28 in a non-displaceable manner by means of the pivot shaft. Accordingly, as the first carriage 28 moves upon actuation of the first electric motor 34, the carriages 28, 52 move synchronously.

Unter Bezugnahme auf Fig. 7 wird nachfolgend der Verstellantrieb 38 näher erläutert.With reference to 7 the adjustment drive 38 is explained in more detail below.

Der Verstellantrieb 38 weist einen zweiten Linearantrieb mit einem zweiten Elektromotor 54 und einem zweiten Spindeltrieb 56 auf.The adjustment drive 38 has a second linear drive with a second electric motor 54 and a second spindle drive 56 .

Auf einer zweiten Gewindespindel des zweiten Spindeltriebs 56 ist verdrehsicher eine zweite Spindelmutter 58 angeordnet. Die zweite Spindelmutter bildet das Abtriebsorgan des zweiten Spindeltriebs 56. Bei Betätigung des zweiten Elektromotors 54 dreht sich die zweite Gewindespindel, so dass sich die zweite Spindelmutter 58 in Axialrichtung der zweiten Gewindespindel in der einen oder anderen Richtung bewegt entsprechend dem Drehsinn der zweiten Gewindespindel.A second spindle nut 58 is arranged on a second threaded spindle of the second spindle drive 56 so that it cannot rotate. The second spindle nut forms the output element of the second spindle drive 56. When the second electric motor 54 is actuated, the second threaded spindle rotates so that the second spindle nut 58 moves in one direction or the other in the axial direction of the second threaded spindle, corresponding to the direction of rotation of the second threaded spindle.

Wie in Fig. 7 dargestellt, ist zum Verdrehen bzw. Verschwenken der Schwenkwelle 46 um ihre Schwenkachse bei einer Linearbewegung der zweiten Spindelmutter 58 eine Verbindungslasche 60 vorgesehen. Ein erstes Ende der Verbindungslasche 60 ist an einem ersten Gelenkpunkt 62 gelenkig mit der zweiten Spindelmutter verbunden, während ein zweites Ende der Verbindungslasche 60 an einem zweiten Gelenkpunkt 64 mit der Schwenkwelle 46 verbunden ist, und zwar exzentrisch zu deren Schwenkachse, derart, dass die Schwenkwelle 46 bei einer Linearbewegung der zweiten Spindelmutter 58 verschwenkt.As in 7 shown, a connecting bracket 60 is provided for rotating or pivoting the pivot shaft 46 about its pivot axis during a linear movement of the second spindle nut 58 . A first end of the connecting strap 60 is pivoted at a first pivot point 62 to the second spindle nut, while a second end of the connecting strap 60 at a second articulation point 64 is connected to the pivot shaft 46, specifically eccentrically to its pivot axis, in such a way that the pivot shaft 46 pivots when the second spindle nut 58 moves linearly.

Zur Ansteuerung der Elektromotoren 34, 54 ist eine Steuerungseinrichtung 64 (vgl. Fig. 2) vorgesehen.A control device 64 (cf. 2 ) intended.

Bei Betätigung des ersten Elektromotors 34 werden die Schlitten 28, 52 relativ zu den Latten 22, 24 entlang der Linearführungen 44, 50 positioniert, um die Latten 22, 24 in dem jeweiligen Bereich zu beaufschlagen.When the first electric motor 34 is actuated, the carriages 28, 52 are positioned relative to the slats 22, 24 along the linear guides 44, 50 in order to act on the slats 22, 24 in the respective area.

Bei Betätigung des zweiten Elektromotors 54 verschwenkt die Schwenkwelle 46, so dass die Druckelemente 36, 36' die jeweiligen Latten durch Druckbelastung beaufschlagen. Die Intensität des resultierenden Massageeffekts ist durch Steuerung des Schwenkwinkels steuerbar.When the second electric motor 54 is actuated, the pivot shaft 46 pivots, so that the pressure elements 36, 36' apply pressure to the respective slats. The intensity of the resulting massage effect can be controlled by controlling the swivel angle.
