Description

Aufrichtrollstuhl Stand-up wheelchair
Die Erfindung betrifft einen Aufrichtrollstuhl mit einem Fahrgestell und einem am vorderen Teil des Fahrgestells befestigten Aufrichtgestell, mit dem ein am vorderen Teil des Fahrgestells schwenkbar befestigter Sitz verbunden ist, der über einen Aktuator von einer Sitzposition in eine Stehposition bringbar ist, einer gelenkig mit dem Sitz verbundenen Rückenlehne mit einem Rückenlehnenpolster, und mit mindestens einem unterhalb des Sitzes schwenkbar am vorderen Teil des Fahrgestells angeordneten Gelenkparallelogramm.The invention relates to a Aufrichtrollstuhl with a chassis and attached to the front of the chassis Aufrichtgestell, with a pivotally attached to the front part of the chassis seat is connected, which can be brought via an actuator from a sitting position to a standing position, a hinged to the seat associated backrest with a backrest cushion, and with at least one below the seat pivotally mounted on the front part of the chassis arranged articulated parallelogram.
Ein solcher Aufrichtrollstuhl ist beispielsweise aus der EP 0 815 822 B1 bekannt.Such a Aufrichtrollstuhl is known for example from EP 0 815 822 B1.
Die über einen langen Zeitraum andauernde sitzende Körperhaltung eines Rollstuhlfahrers führt zum physischen Abbau von Körperfunktionen, wie zum Beispiel reduzierte Beweglichkeit der unteren Gliedmaße, Verlangsamung der Darmaktivitäten und Verschlechterung der Blutzirkulation. Durch das Sitzen besteht außerdem die Gefahr eines Dekubitus. Ein Aufrichtrollstuhl hilft, diese Folgen zu reduzieren, da durch Veränderung der Körperhaltung, bis hin zum Stehen, der Abbau der Körperfunktionen reduziert wird. Die schwenkbare Sitzfläche wird mit Rücken- und Fußstütze auf ein Fahrgestell montiert. Die korrekte Anpassung an die anatomischen Erfordernisse des Benutzers ist ein sehr wichtiges Kriterium für den Komfort, den der Rollstuhl bietet.The long-term sitting posture of a wheelchair user leads to the physical degradation of bodily functions, such as reduced mobility of the lower limbs, slowing of bowel activities, and worsening of blood circulation. Sitting also causes the risk of decubitus. A sit-up wheelchair helps to reduce these consequences, as changing the posture to the point of standing reduces the degradation of body functions. The swivel seat is mounted on a chassis with backrest and footrest. The correct adaptation to the anatomical requirements of the user is a very important criterion for the comfort offered by the wheelchair.
Aufrichtrollstühle bieten dem Benutzer auch die Möglichkeit, sich sportlich zu betätigen. So kann der Behinderte beispielsweise Golf spielen. In einem solchen Fall ist es besonders wichtig, dass der Rollstuhl in der aufgerichteten Position eine hohe Standfestigkeit bietet. So ist beispielsweise eine Anforderung, dass die Fußstütze in der aufgerichteten Position auf dem Erdboden aufsteht bzw. sich auf ihm abstützt. Die Rückenlehne muss parallel zur Sitzfläche stehen und dem Golfer muss ausreichend Bewegungsmöglichkeit (Drehen des Oberkörpers) geboten werden, um zum Schlag schwingen zu können.Raising wheelchairs also offer the user the opportunity to exercise. For example, the disabled person can play golf. In such a case it is especially important that the wheelchair is in the upright position Position provides high stability. For example, a requirement is that the footrest stand up in the raised position on the ground or be supported on it. The backrest must be parallel to the seat and the golfer must be provided with sufficient movement (turning of the upper body) to be able to swing to the beat.
Beim Wechsel von der Sitzposition in die Stehposition (und umgekehrt) behält die Rückenlehne mittels einer Mechanik ihre vertikale Lage bei. Wenn die Drehachse der Rückenlehne und die (knöcherne) Achse des Hüftgelenks des Benutzers zusammenfallen, wird eine Scherbewegung zwischen dem Körper des Benutzers und der Rückenlehne (Hemden-Auszieh-Effekt) vermieden. Die Drehachsen fallen aber in der Regel nicht zusammen. Um die Scherbewegung zu vermeiden, ist bei dem bekannten Rollstuhl das Rücken- lehnenpolster relativ zur Rückenlehne verschiebbar und so mit dem Sitz verbunden, dass es entsprechend der Winkelneigung des Sitzes in vertikaler Richtung verschoben wird.When changing from the sitting position to the standing position (and vice versa), the backrest maintains its vertical position by means of a mechanism. When the axis of rotation of the backrest and the (bony) axis of the user's hip joint coincide, a shearing motion between the user's body and the backrest (shirt pull-out effect) is avoided. The axes of rotation usually do not coincide. In order to avoid the shearing movement, in the known wheelchair, the backrest cushion is displaceable relative to the backrest and connected to the seat in such a way that it is displaced in the vertical direction in accordance with the angle of inclination of the seat.
Die vertikale Lage der Rückenlehne ist beim Aufrichten und Absenken ge- wünscht, damit der Oberkörper des den Rollstuhl benutzenden Menschen ebenfalls in der vertikalen Lage bleibt. Wird jedoch die Sitzfläche negativ geneigt, also der hintere Teil der Sitzfläche gegenüber dem vorderen Teil abgesenkt, was als Kantelung bezeichnet wird, wobei der Nutzer eine bequemere oder sichere Sitzstellung einnehmen möchte, so verkleinert sich bei dem be- kannten Gelenkparallelogramm der Winkel zwischen Sitzfläche und Rückenlehne. Bei diesem Vorgang wird der Nutzer eingezwängt und erleidet körperliche Beschwerden wie Atemnot, Übelkeit usw..The vertical position of the backrest is desired when raising and lowering, so that the upper body of the person using the wheelchair also remains in the vertical position. However, if the seat surface is tilted negatively, that is to say the rear part of the seat surface is lowered relative to the front part, which is called tilting, whereby the user would like to assume a more comfortable or secure sitting position, the angle between the seat surface and the seat frame diminishes in the case of the known articulated parallelogram Backrest. In this process, the user is squeezed and suffers physical discomfort such as shortness of breath, nausea, etc ..
Von dieser Problemstellung ausgehend soll der eingangs beschriebene Auf- richtrollstuhl verbessert werden. Zur Problemlösung zeichnet sich ein gattungsgemäßer Rollstuhl dadurch aus, dass der Neigungswinkel des Sitzes veränderbar ist und bei einer Veränderung des Neigungswinkels des Sitzes aus der Horizontalen der Winkel αi zwischen der Rückenlehne und dem Sitz in einen Winkel α2 verändert wird.Based on this problem, the Aufrichtrollstuhl described above is to be improved. To solve the problem, a generic wheelchair is characterized in that the inclination angle of the seat is variable and is changed in a change in the angle of inclination of the seat from the horizontal angle αi between the backrest and the seat in an angle α 2 .
Die Größe der Veränderung des Winkels hängt vorzugsweise von der Größe der Veränderung des Neigungswinkels ab. Dadurch verändert sich der freie Bereich zwischen Sitzfläche und Rückenlehne selbsttätig, wenn der Sitz sich neigt, so dass ausgeschlossen ist, dass der Nutzer eingezwängt wird, weil der Winkel α2 größer ist als der Winkel eh.The amount of change of the angle preferably depends on the magnitude of the change in the inclination angle. As a result, the free area between the seat and back automatically changes when the seat tilts, so that it is impossible that the user is squeezed because the angle α 2 is greater than the angle eh.
Die Veränderung des Winkels erfolgt vorzugsweise durch eine Verlagerung eines vorderen Gelenkpunktes des Gelenkparallelogrammes in Fahrtrich- tung.The change in the angle is preferably carried out by a displacement of a front pivot point of the articulated parallelogram in the direction of travel.
Zur Einstellung des Neigungswinkels des Sitzes ist vorzugsweise der vordere Teil des Fahrgestelles teleskopierbar ausgebildet. Insbesondere vorteilhaft ist es, wenn der Rahmen des Fahrgestelles an dieser Stelle als Teleskoprohr ausgebildet ist.To adjust the angle of inclination of the seat, the front part of the chassis is preferably designed to be telescopic. It is particularly advantageous if the frame of the chassis is formed at this point as a telescopic tube.
Der vordere Gelenkpunkt ist vorzugsweise über einen schwenkbar befestigten Hebel mit dem Fahrgestell verbunden und in einer Gleitführung an dem verschiebbaren Bauteil des vorderen Teils gelagert.The front pivot point is preferably connected via a pivotally mounted lever to the chassis and mounted in a sliding guide on the displaceable member of the front part.
Die Verschiebung des vorderen Gelenkpunktes in Fahrtrichtung erfolgt vorzugsweise dadurch, dass die Gleitführung gegenüber der Teleskopierrich- tung in einem Winkel geneigt ist.The displacement of the front pivot point in the direction of travel preferably takes place in that the sliding guide is inclined at an angle relative to the telescoping direction.
Eine einfache Gleitführung ist erreichbar, wenn diese durch ein mit einem Langloch versehenen Blech gebildet wird. Das Blech kann mit dem Bauteil verschraubt sein. Wenn der Winkel, mit dem die Gleitführung geneigt ist, einstellbar ist, kann die Größe des sich einstellenden Winkels Ö2 variiert werden.A simple sliding guide is achievable if it is formed by a plate provided with a slot. The sheet metal can be screwed to the component. If the angle at which the sliding guide is inclined, is adjustable, the size of the adjusting angle Ö2 can be varied.
Der Neigungswinkel ß der Rückenlehne kann vorzugsweise dadurch einge- stellt werden, dass die Gleitführung verschiebbar ist. Die Verschiebbarkeit kann dadurch erreicht werden, dass die Befestigungsstelle der Gleitführung an dem teleskopierbaren Bauteil in Fahrtrichtung veränderbar ist.The inclination angle β of the backrest can preferably be adjusted by the sliding guide being displaceable. The displaceability can be achieved in that the attachment point of the sliding guide on the telescopic component is changeable in the direction of travel.
Wenn ein um eine Umlenkrolle geführtes Gurtband mit seinem einen Ende an dem den Sitz tragenden Lenker und mit seinem anderen Ende mit dem relativ zur Rückenlehne verschiebbaren Rückenpolster befestigt ist, kann dasIf a guided around a pulley webbing is fastened with its one end to the seat-carrying handlebar and with its other end with the relative to the backrest displaceable back pad, the
Gurtband das Rückenpolster an der Rückenlehne nach oben ziehen, wenn der Sitz von der Stehposition in die Sitzposition gebracht wird, so dass keinePull up the back pad padding on the backrest when the seat is moved from the standing position to the sitting position, so that no
Relativbewegung zwischen dem Rückenpolster und dem Rücken des Nut- zers entsteht.Relative movement between the back cushion and the back of the user arises.
Der Weg, um den die Rückenlehne nach oben gezogen wird, ist vorzugsweise einstellbar. Zur Einstellung kann ein Verstellblech vorgesehen sein, dessen Länge relativ zum unmittelbar unter dem Sitz angeordneten Hebel ein- stellbar ist.The way by which the backrest is pulled upwards is preferably adjustable. For adjustment, an adjusting plate may be provided, the length of which is adjustable relative to the lever arranged directly under the seat.
Vorzugsweise sind zwei parallel nebeneinander angeordnete Gelenkparallelogramme vorgesehen, die den Sitz aufnehmen. Preferably, two parallel juxtaposed Gelenkparallelogramme are provided which receive the seat.

Auf der Unterseite der Sitzfläche 10 ist ein Sitzblech 31 vorgesehen, das auf dem Hebel 1 aufliegt. Das Sitzblech 31 weist ein Befestigungsblech 4 für den Aktuator 6 und ein Befestigungsblech 83 für das Verstellblech 65 auf. An dem am Sitzblech 31 befindlichen Befestigungsblech 4 ist ein Ende des Ak- tuators 6 befestigt, das andere Ende ist an dem am Führungsgestell 20 befestigten Lagerblech 9 angelenkt. Wird der Aktuator 6 teleskopiert, wird die in Figur 7 gezeigte Sitzposition in die in Figur 9 gezeigte Stehposition überführt. Dabei wird mittels des Gelenkparallelogrammes 45 die Rückenlehne 24, an der das Rückenlehnenpolster 17 befestigt ist, nachgeführt. Hierzu ist der Ak- tuator 6 um die Drehachse 30 am Befestigungsblech 4 und die Drehachse 29 am Lagerblech 9 schwenkbar gelagert.On the underside of the seat 10, a seat plate 31 is provided, which rests on the lever 1. The seat plate 31 has a mounting plate 4 for the actuator 6 and a mounting plate 83 for the adjusting plate 65. One end of the actuator 6 is fastened to the attachment plate 4 located on the seat panel 31, the other end being articulated to the bearing plate 9 fastened to the guide frame 20. When the actuator 6 is telescoped, the seating position shown in FIG. 7 is transferred to the standing position shown in FIG. In this case, by means of the Gelenkparallelogrammes 45, the backrest 24 to which the backrest cushion 17 is attached, tracked. For this purpose, the tuator 6 pivotally mounted about the axis of rotation 30 on the mounting plate 4 and the axis of rotation 29 on the bearing plate 9.
Nachfolgend soll die Funktionsweise der Gelenkparallelogramme 45 nur noch anhand eines Gelenkparallelogrammes erläutert werden, da beide Gelenkparallelogramme 45 identisch aufgebaut sind.Below, the mode of operation of the articulated parallelograms 45 will only be explained on the basis of an articulated parallelogram, since both articulated parallelograms 45 are identically constructed.
Der obere Hebel 1 , der untere Hebel 2 und das Sitzblech 31 sind zweigeteilt. Die Teile 1a, 1b, 2a, 2b und 31a und 31b sind mit zueinander korrespondie- renden Bohrungen versehen, über die die Hebel 1a, 1b und 2a, 2b sowie die Sitzblechteile 31a, 31b in ihrer Länge einstellbar miteinander verschraubt werden können. Der Abstand der Gelenkpunkte 11-12 bzw. 13-14 ist somit einstellbar.The upper lever 1, the lower lever 2 and the seat plate 31 are divided into two parts. The parts 1a, 1b, 2a, 2b and 31a and 31b are provided with mutually corresponding holes through which the levers 1a, 1b and 2a, 2b and the seat sheet metal parts 31a, 31b can be screwed adjustably in their length. The distance of the hinge points 11-12 and 13-14 is thus adjustable.
Der zur Rückenlehne gehörende Hebel 3 des Gelenkparallelogrammes 45 bildet die Gelenkpunkte 11 und 12. Die Rückenlehne 24 schwenkt um den Gelenkpunkt 12.The belonging to the backrest lever 3 of the Gelenkparallelogrammes 45 forms the hinge points 11 and 12. The backrest 24 pivots about the hinge point 12th
Aus der in Figuren 7 und 8 gezeigten Sitzposition heraus beginnt im Allge- meinen das Aufrichten. Durch Ausfahren des Aktuators 6 verändert sich der Abstand der Gelenkpunkte 29 und 30, so dass sich der Sitz 10 um die Drehachse 11 schwenkt. Dabei bleiben die Gelenkpunkte 11 und 14 in ihrer Position. Das Gelenkparallelogramm 45 bewegt sich zusammen mit dem Sitz 10. Über den unteren Hebel 2 mit den Gelenkpunkten 13 und 14 wird die vertika- Ie Ausrichtung der Rückenlehne 24 beibehalten. Es wird davon gesprochen, dass der Hebel 2 die Rückenlehne 24 aufrichtet. Mit Hilfe des oberen Hebels 1 wird die Rückenlehne 24 mit dem Gelenkpunkt 12 positioniert.From the sitting position shown in FIGS. 7 and 8, erecting generally begins. By extending the actuator 6, the distance between the hinge points 29 and 30, so that the seat 10 pivots about the axis of rotation 11. The hinge points 11 and 14 remain in position. The articulated parallelogram 45 moves together with the seat 10. About the lower lever 2 with the hinge points 13 and 14, the vertical Ie alignment of the backrest 24 is maintained. It is said that the lever 2 upright the backrest 24. With the help of the upper lever 1, the backrest 24 is positioned with the hinge point 12.
Die Rückenlehne 24 besteht aus dem Rückenträger 66 mit der Umlenkrolle 81 und dem Rückenblech 67 mit dem Rückenlehnenpolster 17. Das Rückenblech 67 wird im Rückenträger 66 gleitend und stufenlos einstellbar gelagert. Das Gurtband 68 ist an seinem einen Ende mit dem eine Befestigungsachse 82 aufweisenden Verstellblech 65, das an dem oberen Hebel 1 befestigt ist, und über die Umlenkrolle 81 am anderen Ende mit dem Rückenblech 67 verbunden.The backrest 24 consists of the back support 66 with the deflection roller 81 and the back plate 67 with the backrest cushion 17. The back plate 67 is mounted in the back support 66 slidably and continuously adjustable. The webbing 68 is at its one end with the one attachment axis 82 having adjusting plate 65 which is fixed to the upper lever 1, and connected via the guide roller 81 at the other end with the back plate 67.
Infolge der Abstandsänderung Y1-Y2 der Befestigungsachse 82 und der Umlenkrolle 81 gleitet beim Aufrichten der Sitzfläche 10 das Rückenblech 67 nach unten. Dabei wird gleichzeitig der Abstand Z zwischen dem Rückenblech 67 mit dem Rückenlehnenpolster 17 und der Sitzfläche des Sitzes 10 verkürzt (siehe Abstand Zi in Figur 4 und Z2 in Figur 6). Es findet ein anato- mischer Rückenausgleich statt, der eine Scherbewegung zwischen dem Rückenlehnenpolster 17 und dem Rücken des Nutzers ausschließt.As a result of the change in distance Y 1 -Y 2 of the mounting axis 82 and the guide roller 81 slides when erecting the seat 10, the back plate 67 down. At the same time the distance Z between the back plate 67 with the backrest cushion 17 and the seat surface of the seat 10 is shortened (see distance Zi in Figure 4 and Z 2 in Figure 6). There is an anatomic back balancing that precludes shearing movement between the back pad 17 and the user's back.
Die Position der Befestigungsachse 82 ist über zueinander korrespondierende Bohrungen im Verstellblech 65 und im am Hebel 1b befestigten Befesti- gungsblech 83 veränderbar. Die Positionsänderung der Befestigungsachse 82 relativ zum Gelenkpunkt 12 hat direkten Einfluss auf den Rückenausgleich. Somit kann der Rückenausgleich individuell auf den Nutzer eingestellt werden.The position of the attachment axis 82 can be changed via mutually corresponding bores in the adjustment plate 65 and in the attachment plate 83 fastened to the lever 1b. The change in position of the attachment axis 82 relative to the hinge point 12 has a direct influence on the back compensation. Thus, the back compensation can be adjusted individually to the user.
Um beim Kantein den Neigungswinkel Y der Sitzfläche zu verändern, muss der vertikale Abstand zwischen den Gelenkpunkten 11 und 14 verändert werden. Hierzu wird die Führungssäule 5 stufenlos zum Führungsgestell 20 teleskopiert. Wird der Abstand Xi durch Herausziehen der Führungssäule 5 aus dem Führungsgestell 20 vergrößert (Änderung von Xi auf X2), neigt sich der Sitz um den Gelenkpunkt 30 schwenkend nach hinten (vgl. Figur 5). Gleichzeitig ändert sich der Abstand des Gelenkpunktes 14 relativ zum Gelenkpunkt 11. Hierbei gleitet der sich am ortsfest schwenkbar gelagerten Hebel 22 befindliche Gelenkpunkt 14 in der Nut oder Langloch 8 im Führungsblech 7, das eine Gleitführung bildet, in Fahrtrichtung F nach vorn, denn der Gelenkpunkt 16 ist mit dem Führungsgestell 20 verbunden. Dabei verändert sich gleichzeitig auch der Winkel zwischen der Rückenlehne 24 und dem Sitz 10 von CH - Ci2. Die Änderung des Winkels α ist abhängig vom Neigungswinkel Y und der Abstandsänderung von Xi - X2. Der sich vergrößernde Winkel α führt zu einer besseren Druckentlastung für den Oberkörper des Nutzers und somit zu einer Reduzierung der Dekubitusgefahr.In order to change the inclination angle Y of the seat at the edge, the vertical distance between the hinge points 11 and 14 must be changed. For this purpose, the guide column 5 is telescoped to the guide frame 20 stepless. If the distance Xi is increased by pulling the guide column 5 out of the guide frame 20 (change from Xi to X 2 ), the seat tilts around the hinge point 30 in a pivoting manner towards the rear (compare FIG. At the same time, the distance of the hinge point 14 relative to the hinge point 11 changes. In this case, the hinge point 14 located on the pivotally mounted lever 22 slides in the groove or slot 8 in the guide plate 7, which forms a sliding guide, in the direction of travel F, because the hinge point 16 is connected to the guide frame 20. At the same time, the angle between the backrest 24 and the seat 10 of CH - Ci 2 also changes . The change in the angle α depends on the angle of inclination Y and the change in distance of Xi - X 2 . The increasing angle α leads to a better pressure relief for the upper body of the user and thus to a reduction of pressure ulcer.
Zur weiteren Entlastung kann in der Sitzposition der Neigungswinkel ßi der Rückenlehne 24 durch Versetzen der Führungsplatte 7 innerhalb der korrespondierenden Bohrungen in der Führungssäule 5 verändert werden. Der Neigungswinkel ß2 in der Stehposition wird durch das Versetzen des Führungsbleches 7 nicht beeinflusst. For further relief can be changed in the seat position of the inclination angle ßi the backrest 24 by moving the guide plate 7 within the corresponding holes in the guide column 5. The inclination angle ß 2 in the standing position is not affected by the displacement of the guide plate 7.
