Description

Die Erfindung betrifft eine verstellbare Kopfstützeneinheit für Sitzvorrichtungen, insbesondere Rollstühle oder Aufrichtrollstühle, mit einer Kopfstütze, mit einem Halter, der an der Sitzvorrichtung befestigbar ist und eine Vorrichtung zur praktisch horizontalen Verstellung der Kopfstütze aufweist.The invention relates to an adjustable headrest unit for seat devices, in particular wheelchairs or Aufrichtrollstühle, with a headrest, with a holder which is attachable to the seat device and having a device for virtually horizontal adjustment of the headrest.

Die US 5,366,036 zeigt einen Aufrichtrollstuhl mit einem höhenverstellbaren stabförmigen Halter. An diesem ist oben ein Vierkantrohrstück angeschweisst, in welchem ein vierkantiger Kopfstützenträger mit der Kopfstütze horizontal verschoben und in der gewünschten Stellung fixiert werden kann. Diese Verstellung kann natürlich nicht vom behinderten Benützer des Rollstuhls vorgenommen werden.The US 5,366,036 shows a Aufrichtrollstuhl with a height-adjustable rod-shaped holder. At this top a square pipe piece is welded, in which a four-sided headrest support can be moved horizontally with the headrest and fixed in the desired position. Of course, this adjustment can not be made by the disabled user of the wheelchair.

US 3, 730, 589 zeigt einen Rollstuhl mit einem vertikalen Stab, an welchem eine Kopfstütze mittels einer Klemmvorrichtung befestigt ist. Diese Klemmvorrichtung ist so ausgebildet, dass sie eine vertikale und horizontale Verstellung der Kopfstütze erlaubt. In der vertikalen Ebene kann auch der Winkel verstellt werden (Spalte 2, Zeile 65 bis Spalte 3, Zeile 5). Diese Verstellungen können aber nicht vom behinderten Benützer des Rollstuhls vorgenommen werden. US Pat. No. 3,730,589 shows a wheelchair with a vertical rod, to which a headrest is attached by means of a clamping device. This clamping device is designed so that it allows a vertical and horizontal adjustment of the headrest. The angle can also be adjusted in the vertical plane (column 2, line 65 to column 3, line 5). These adjustments can not be made by the disabled user of the wheelchair.

Die US 6, 726, 280 zeigt einen Mechanismus in Form eines Hebelparallogrammes zur gleichzeitigen Verstellung einer Rückenstütze in vertikaler und horizontaler Richtung. Für eine Kopfstütze ist dies jedoch nicht zweckmässig, denn dem Rollstuhlbenützer soll es möglich sein, eine Verstellung in der horizontalen Richtung, unabhängig von einer Verstellung in der vertikalen Richtung vorzunehmen.The US 6, 726, 280 shows a mechanism in the form of a Hebelparallogrammes for simultaneous adjustment of a back support in the vertical and horizontal directions. For a headrest, however, this is not appropriate, because the wheelchair users should be able to make an adjustment in the horizontal direction, regardless of an adjustment in the vertical direction.

Den gleichen Nachteil wie die Mechanik der US 6,726,280 besitzt auch der als Hebelparallelogramm ausgebildete Mechanismus gemäss US 6, 550, 856 . Die Kopfstütze ist seitlich am Hebelparallelogramm angelenkt. Dies hat zur Folge, dass beim Schwenken der Rückenlehne die Kopfstütze nach vom und nach unten bewegt wird, um die Gesamtlänge der Rückenlehne zu verkürzen, so dass die Kopfstütze nicht mit dem Dach oder der Sonnenblende eines Autos niedriger Bauart kollidiert (Spalten 1, Zeilen 28 bis 32, Fig. 3a). Für einen Rollstuhl ist diese Konstruktion ungeeignet. Sie hat auch den Nachteil, dass die Kopfstütze nicht entfernt werden kann.The same disadvantage as the mechanics of US 6,726,280 also has the trained as a lever parallelogram mechanism according US Pat. No. 6,550,856 , The headrest is articulated laterally on the lever parallelogram. This has the consequence that when tilting the backrest, the headrest is moved up and down to shorten the overall length of the backrest, so that the headrest does not collide with the roof or sun visor of a low-profile car (columns 1, lines 28 to 32; Fig. 3a ). For a wheelchair, this construction is unsuitable. It also has the disadvantage that the headrest can not be removed.

In der US 4,840,429 wird eine Kopfstütze für einen Zahnarztstuhl beschrieben. Sie besitzt einen plattenförmigen Halter, welcher am Zahnarztstuhl befestbar ist. Am Halter sind in unterschiedlicher Höhenlage ein erster und ein zweiter plattenförmiger Hebel angelenkt, welche sich nach oben erstrecken. Der zweite plattenförmige Hebel besitzt an jeder Seite eine hakenförmige Verlängerung, welche in das Gehäuse der Kopfstütze ragt und eine Rolle aufweist, die entlang einer schräg angeordneten Führung laufen kann. Der erste plattenförmige Hebel ist an einem Schlitten angelenkt, der die schräg angeordnete Führung trägt und durch einen Motor hin und her beweglich ist, um die in Fig. 5 dargestellte Schwenklagen der Kopfstütze zu ermöglichen, welche für die zahnärztliche Behandlung des Oberkiefers bzw. des Unterkiefers zweckmässig sind. Diese Kopfstütze ermöglicht keine praktisch horizontale Verstellung und ist daher für Rollstühle völlig ungeeignet.In the US 4,840,429 is described a headrest for a dentist chair. It has a plate-shaped holder, which is attachable to the dentist chair. On the holder a first and a second plate-shaped lever are hinged at different altitudes, which extend upwards. The second plate-shaped lever has on each side a hook-shaped extension which projects into the housing of the headrest and has a roller which can run along an obliquely arranged guide. The first plate-shaped lever is hinged to a carriage, which carries the obliquely arranged guide and is movable by a motor back and forth to allow the pivoting positions of the headrest shown in Fig. 5, which for the dental treatment of the maxilla and the lower jaw are appropriate. This headrest does not allow virtually horizontal adjustment and is therefore completely unsuitable for wheelchairs.

Es ist Aufgabe der vorliegenden Erfindung eine verstellbare Kopfstützeneinheit der eingangs erwähnten Gattung zu schaffen, welche leicht vom Rollstuhlbenützer bedienbar ist und auch ästhetischen Ansprüchen genügt. Die Kopfstütze soll insbesondere eine Verstellung in einer Richtung, z.B. in praktisch horizontaler Richtung ermöglichen, ohne dass dabei zusätzlich eine Verstellung in einer anderen Richtung erfolgt. Weiter soll die Gefahr eines Einklemmens von Fingern oder Gegenständen vermieden werden.It is an object of the present invention to provide an adjustable headrest unit of the type mentioned, which is easily operated by the wheelchair user and also satisfies aesthetic requirements. In particular, the headrest is intended to be adjusted in one direction, e.g. allow in virtually horizontal direction, without causing an additional adjustment in another direction. Next, the risk of pinching fingers or objects should be avoided.

Erfindungsgemäss wird dies durch den Gegenstand von Anspruch 1 erreicht. Da im Gegensatz zum Gegenstand der US 6,550,856 die Hebelmechanik oben und nicht seitlich am Halter angelenkt ist, wird bei einer horizontalen Verstellung der Kopfstütze diese nicht spürbar in vertikaler Richtung bewegt. Aus dem gleichen Grund ist eine schlanke und formschöne Konstruktion der Kopfstützeneinheit möglich. Dazu trägt noch bei, dass das Antriebsorgan fern vom Kopf des Benützers an geeigneter Stelle der Sitzvorrichtung angebracht werden kann. Ein weiterer Vorteil besteht auch darin, dass z.B. für den Transport der Halter zusammen mit der Hebelmechanik und der Kopfstütze leicht entfernt werden kann. Weil die Hebel der Hebelmechanik einander in jeder der verschiedenen möglichen Stellungen überlappen besteht keine Gefahr eines Einklemmens von Fingern oder irgendwelchen Gegenständen. Da die Hebelmechanik schlank ausgebildet werden kann, ist es auch möglich eine Verkleidung vorzunehmen. Dies trägt zur Ästhetik der verstellbaren Kopfstützeneinheit bei. Entsprechendes gilt auch für die Möglichkeit, die Hebelmechanik bogenförmig auszubilden.According to the invention this is achieved by the subject matter of claim 1. As opposed to the subject of the US 6,550,856 the lever mechanism is hinged at the top and not laterally on the holder, it is not noticeably moved in a vertical direction with a horizontal adjustment of the headrest. For the same reason, a slim and shapely construction of the headrest unit is possible. This contributes to the fact that the drive member can be mounted away from the user's head at a suitable location of the seat device. Another advantage is also that, for example, for the transport of the holder together with the lever mechanism and the headrest are easily removed can. Because the levers of the lever mechanism overlap each other in each of the various possible positions, there is no danger of pinching fingers or any objects. Since the lever mechanism can be made slim, it is also possible to make a disguise. This contributes to the aesthetics of the adjustable headrest unit. The same applies to the possibility of forming the lever mechanism arcuate.

Als Verbindungsglied zum Antriebsorgan könnte beispielsweise eine Stange dienen. Weil aber die Kopfstütze leicht höhenverstellbar sein sollte, ist dies nicht besonders praktisch. Vorteilhaft wird daher als Verbindungsglied eine flexible Vorrichtung, z.B. ein Bowden-Zug, verwendet. Dies erlaubt problemlos eine Höhenverstellung der Kopfstütze.As a link to the drive member could serve for example a rod. But because the headrest should be slightly height adjustable, this is not very practical. Advantageously, therefore, a flexible device, such as a Bowden train used as a link. This allows easy height adjustment of the headrest.

Die Hebelmechanik kann einen einzigen Hebel aufweisen, der oben mit der Kopfstütze verbunden ist. Dies ergibt eine sehr einfache Konstruktion. Vorteilhafter ist jedoch ein Hebelparallelogramm, weil mit einem solchen eine Bewegung der Kopfstütze erzielt werden kann, die besser den anatomischen Gegebenheiten des Benützers entspricht. Die Verbindung der Hebelmechanik mit der Kopfstütze kann starr oder gelenkig ausgestaltet sein. Gegebenenfalls können auch Arretiermittel für die gelenkige Verbindung vorgesehen werden.The lever mechanism may have a single lever, which is connected at the top with the headrest. This results in a very simple construction. More advantageous, however, is a lever parallelogram, because with such a movement of the headrest can be achieved, which better corresponds to the anatomical conditions of the user. The connection of the lever mechanism with the headrest can be designed rigid or articulated. Optionally, locking means for the articulated connection can be provided.

Eine vorteilhafte Ausführung sieht vor, dass das Hebelparallelogramm einen ersten und einen zweiten Hebel aufweist, deren Anlenkstellen unten praktisch auf gleicher Höhe und in einem Abstand voneinander am Halter und oben praktisch auf gleicher Höhe und im Abstand voneinander an einem Verbindungsstück angelenkt sind.An advantageous embodiment provides that the lever parallelogram has a first and a second lever, the articulation points are hinged down practically at the same height and at a distance from each other on the holder and above practically at the same height and at a distance from each other on a connecting piece.

Vorteilhaft ist dieses Verbindungsstück so ausgestaltet, dass der Abstand zwischen den Anlenkstellen veränderbar ist. Dies erlaubt eine Anpassung der Kopfstützenbewegung an die anatomischen Gegebenheiten des Benützers.Advantageously, this connector is designed so that the distance between the articulation points is changeable. This allows an adaptation of the headrest movement to the anatomical conditions of the user.

Die in den Figuren 1 bis 3 dargestellte Kopfstützeneinheit 10 besitzt einen höhenverstellbaren Halter 11, der in einer an der Sitzeinrichtung 12 befestigbaren Führung 13 vertikal verschiebbar und in der gewünschten Stellung durch Arretiermittel 15, z.Bsp. einer Stellschraube, feststellbar ist. Der Halter 11 weist oben eine Platte 17 auf, welche eine Vorrichtung 18 zur praktisch horizontalen Verstellung einer Kopfstütze 19 trägt. Die Vorrichtung 18 ist eine Hebelmechanik, welche über ein Verbindungsglied 21 mit einem vom Benützer der Sitzvorrichtung steuerbaren Antriebsorgan 23, z.Bsp. einem Linearmotor, verbunden ist. Beim gezeigten Ausführungsbeispiel ist das Verbindungsglied 21 ein sogenannter Bowden-Zug. Ein Bowden-Zug besteht bekanntlich aus einem Kabel 25 und einer Hülle 27.The in the FIGS. 1 to 3 illustrated headrest unit 10 has a height-adjustable holder 11 which is vertically displaceable in a fastened to the seat assembly 12 guide 13 and in the desired position by locking means 15, z.Bsp. a set screw, can be determined. The holder 11 has at the top a plate 17 which carries a device 18 for virtually horizontal adjustment of a headrest 19. The device 18 is a lever mechanism, which via a connecting member 21 with a controllable by the user of the seat device drive member 23, z.Bsp. a linear motor connected. In the embodiment shown, the connecting member 21 is a so-called Bowden train. A Bowden train is known to consist of a cable 25 and a sheath 27th

Beim gezeigten Ausführungsbeispiel ist die Hebelmechanik 18 als Hebelparallelogramm ausgebildet. Dieses Hebelparallelogramm 18 weist einen ersten Hebel 33 und einen zweiten Hebel 35 auf, die bogenförmig ausgebildet sind und in jeder Stellung des Hebelparallelogramms 18 einander überlappen (Figuren 4a - 4c). Die Hebel 33, 35 können von einer Verkleidung umgeben sein (nicht eingezeichnet). Der erste Hebel 33 ist unten bei 37 an der Platte 17 und oben bei 39 am Verbindungsstück 45 angelenkt. Der zweite Hebel 35 ist unten bei 41 an der Platte 17 und oben bei 43 am Verbindungsstück 45 angelenkt. Es ist möglich im Verbindungsstück 45 verschiedene Anlenkstellen, also verschiedene Bohrungen, vorzusehen, damit der Abstand zwischen den Anlenkstellen veränderbar ist. Es ist aber auch möglich das Verbindungsstück 45 zweiteilig auszugestalten, um beispielsweise mit einer Schraube den Abstand zwischen den Anlenkstellen 39 und 43 zu verändern.
Die Kopfstütze 19 kann starr oder mit einem Gelenk 46 am Verbindungsstück 45 befestigt sein.In the embodiment shown, the lever mechanism 18 is formed as a lever parallelogram. This lever parallelogram 18 has a first lever 33 and a second lever 35, which are arc-shaped and in each position of the Hebelparallelogramms 18 overlap each other ( FIGS. 4a-4c ). The levers 33, 35 may be surrounded by a panel (not shown). The first lever 33 is hinged at 37 below on the plate 17 and at the top at 39 on the connector 45. The second lever 35 is hinged at 41 at the bottom of the plate 17 and at the top 43 at the connector 45. It is possible in the connector 45 different articulation points, so different holes to provide, so that the distance between the articulation points is changeable. But it is also possible the connector 45 in two parts to design For example, with a screw to change the distance between the articulation points 39 and 43.
The headrest 19 may be rigid or fixed with a hinge 46 on the connector 45.

Wie bereits erwähnt, verbindet der Bowden-Zug 21 den Linearmotor 23 mit der Hebelmechanik 18. Antriebsseitig ist die Hülle 27 des Bowden-Zugs 21 ist mit einem beweglichen Teil 29 des Linearmotors 23 verbunden, das Kabel 25 hingegen mit einem stationären Teil 31. Bei der Hebelmechanik 18 ist die Hülle 27 des Bowden-Zugs 21 am Arm 47 des doppelarmigen ersten Hebels 33 befestigt. Das Kabel 25 führt über eine Rolle oder Zapfen 49 des zweiten Hebels 35 und ist ebenfalls am Hebelarm 47 befestigt.As already mentioned, the Bowden train 21 connects the linear motor 23 with the lever mechanism 18. On the drive side, the sheath 27 of the Bowden cable 21 is connected to a movable part 29 of the linear motor 23, the cable 25, however, with a stationary part 31. Bei the lever mechanism 18, the sheath 27 of the Bowden cable 21 is attached to the arm 47 of the double-armed first lever 33. The cable 25 passes over a roller or pin 49 of the second lever 35 and is also secured to the lever arm 47.

Wenn sich somit bei einer Betätigung des Linearmotors 23 dessen bewegliches Teil 29 nach unten bewegt, wird der Hebel 33 im Uhrzeigersinn verdreht (Fig. 4b und 4c). Bewegt sich jedoch das bewegliche Teil 29 wieder nach oben, so wandert die Kopfstütze 19, durch Zug der Feder 51, (Fig. 2) nach hinten, in die Stellung von Fig. 4a.Thus, when an operation of the linear motor 23 moves its movable part 29 down, the lever 33 is rotated clockwise ( Fig. 4b and 4c ). However, moves the movable member 29 back up, the headrest 19 moves by train of the spring 51, ( Fig. 2 ) to the rear, in the position of Fig. 4a ,

Zusammenfassend kann folgendes festgehalten werden:In summary, the following can be stated:

Die Kopfstützeneinheit 10 kann mit einem höhenverstellbaren Halter 13 an einer Sitzvorrichtung, z.Bsp. einem Rollstuhl, befestigt werden. Die Kopfstütze 19 kann vom Benützer gesteuert motorisch horizontal in die gewünschte Stellung bewegt werden, ohne dass gleichzeitig eine spürbare und störende Bewegung in vertikaler Richtung erfolgt. Es befindet sich kein störender Motor in der Nähe des Kopfes des Benutzers. Die Kopfstütze 19 wird von einem schlanken und formschönen Hebelparallelogramm 18 getragen, das mit einem flexiblen Bowden-Zug 21 mit einem entfernt angeordneten Motor 23 operativ verbunden ist. Diese flexible Verbindung 21 gestattet nicht nur den Motor 23 an geeigneter Stelle entfernt vom Kopf des Benützers anzuordnen, sondern behindert auch nicht eine Höhenverstellung der Kopfstütze 19 mittels dem vertikalen Halter 11 und der Stellschrauben 15.The headrest unit 10 can with a height-adjustable holder 13 on a seat device, z.Bsp. a wheelchair, to be attached. The headrest 19 can be controlled by the user to move horizontally to the desired position, without at the same time there is a noticeable and disturbing movement in the vertical direction. There is no annoying motor near the user's head. The headrest 19 is supported by a slender and shapely lever parallelogram 18 which is operatively connected to a flexible Bowden cable 21 with a remotely located motor 23. This flexible connection 21 not only allows the motor 23 to be located at a suitable location away from the user's head but also does not hinder a height adjustment of the headrest 19 by means of the vertical holder 11 and the set screws 15.
