Die
Es ist eine Aufgabe der Erfindung, eine Befestigungsvorrichtung zur lösbaren Befestigung eines Rollstuhls in einem Fahrzeug anzugeben, die eine hohe Sicherheit eines Benutzers des Rollstuhls auch bei einem Unfall des Fahrzeuges gewährleistet. Dabei soll die Befestigung des Rollstuhls auch durch einen Rollstuhlbenutzer selbst möglich sein.It is an object of the invention to specify a fastening device for the detachable fastening of a wheelchair in a vehicle, which ensures a high level of safety for a user of the wheelchair even if the vehicle has an accident. The wheelchair user should also be able to attach the wheelchair himself.
Die Lösung der Aufgabe erfolgt durch eine Befestigungsvorrichtung zur lösbaren Befestigung eines Rollstuhls in einem Fahrzeug, umfassend eine mechanisch stabile Tragstruktur unter einem Sitz des Rollstuhl, sowie mindestens zwei im Wesentlichen stangenförmige Befestigungselemente, wobei die Befestigungselemente aus einer zurückgezogenen Position in eine ausgefahrene Position axial verschiebbar sind, wobei die Befestigungselemente an einem ersten Ende axial verschiebbar mit der Tragstruktur verbunden sind und an einem dem ersten Ende gegenüberliegenden zweiten Ende Kontaktpunkte zur Befestigung im Fahrzeug ausgebildet sind, wobei die Befestigungselemente dazu ausgebildet sind, durch einen Benutzer des Rollstuhls axial verschoben zu werden, so dass durch den Benutzer des Rollstuhls die Befestigungselemente in die ausgefahrene Position verschoben werden können und die Kontaktpunkte am Fahrzeug befestigt werden können, wobei die Befestigungsvorrichtung zumindest drei der im Wesentlichen stangenförmigen Befestigungselemente umfasst, wovon zwei Befestigungselemente im Wesentlichen horizontal verschiebbar sind, zur Befestigung des Rollstuhls an einem vertikalen Element des Fahrzeugs und ein Befestigungselement im Wesentlichen vertikal verschiebbar ist, zur Befestigung des Rollstuhls an einem Boden des Fahrzeugs.The object is achieved by a fastening device for the detachable fastening of a wheelchair in a vehicle, comprising a mechanically stable support structure under a seat of the wheelchair, and at least two essentially rod-shaped fastening elements, the fastening elements being axially displaceable from a retracted position into an extended position , wherein the fastening elements are connected to the support structure in an axially displaceable manner at a first end and contact points for fastening in the vehicle are formed at a second end opposite the first end, wherein the fastening elements are designed to be axially displaced by a user of the wheelchair, so that by the user of the wheelchair, the fasteners can be moved to the extended position and the contact points can be attached to the vehicle, wherein the fastening device at least three of the essentially sta n-shaped fastening elements, two fastening elements being displaceable substantially horizontally, for fastening the wheelchair to a vertical element of the vehicle and one fastening element being displaceable substantially vertically is for attaching the wheelchair to a floor of the vehicle.
Erfindungsgemäß weist ein Rollstuhl zur Befestigung in einem Fahrzeug unter der Sitzfläche des Rollstuhls eine Tragstruktur auf, die eine mechanische Stabilität des Rollstuhls selbst bei Unfall gewährleistet. An dieser Tragstruktur sind mechanisch stabile, steife Befestigungselemente zumindest mittelbar befestigt, in einer Weise, so dass die im Wesentlichen stangenförmigen Befestigungselemente axial vor- und zurückgeschoben werden können. Ein freies Ende eines Befestigungselements, das zweite Ende, dient der Befestigung am Fahrzeug. Das andere, erste Ende des Befestigungselements bleibt auch im ausgefahrenen Zustand und somit bei Befestigung des Rollstuhls am Fahrzeug mit der Tragstruktur verbunden, so dass sich ein mechanisch stabiler Rahmen durch den Rollstuhl und durch die stabförmigen Befestigungselemente bis zum Fahrzeug erstreckt. Diese durchgängig stabile Anordnung ermöglicht eine hohe Sicherheit des Benutzers des Rollstuhls auch bei einem Unfall. Die Befestigungselemente sind durch einen Benutzer des Rollstuhls selbst axial verschiebbar und können daher durch den Benutzer in den ausgefahrenen und befestigten Zustand verschoben werden. Die Befestigungselemente sind dazu in geeigneter Weise axial verschiebbar gelagert, so dass eine auftretende Kraft durch die Tragstruktur unter der Sitzfläche des Rollstuhls geleitet wird. Bevorzugt kann auch ein handelsüblicher Rollstuhl mit einer solchen Befestigungsvorrichtung nachgerüstet werden. Dies kann die Nachrüstung des Rollstuhls mit der erforderlichen Tragstruktur inkludieren oder es kann eine bereits am Rollstuhl vorhandene Tragstruktur für die Befestigungsvorrichtung genutzt werden.According to the invention, a wheelchair for attachment in a vehicle has a support structure under the seat of the wheelchair, which ensures mechanical stability of the wheelchair even in the event of an accident. Mechanically stable, rigid fastening elements are attached at least indirectly to this support structure in such a way that the essentially rod-shaped fastening elements can be pushed back and forth axially. A free end of a fastener, the second end, is used for attachment to the vehicle. The other, first end of the fastening element remains connected to the support structure even in the extended state and thus when the wheelchair is fastened to the vehicle, so that a mechanically stable frame extends through the wheelchair and through the rod-shaped fastening elements to the vehicle. This consistently stable arrangement enables a high level of safety for the user of the wheelchair, even in the event of an accident. The fastening elements can be moved axially by a user of the wheelchair himself and can therefore be moved into the extended and fastened state by the user. For this purpose, the fastening elements are mounted so that they can be displaced axially in a suitable manner, so that any force that occurs is conducted through the supporting structure under the seat surface of the wheelchair. A commercially available wheelchair can preferably also be retrofitted with such a fastening device. This can include retrofitting the wheelchair with the necessary support structure, or a support structure that is already present on the wheelchair can be used for the attachment device.
Die Befestigungselemente sind stangenförmig, und weisen daher eine lange zylindrische Form auf, wobei der Querschnitt der Befestigungselemente rund sein kann, jedoch auch andere Formen umfasst sind, wie beispielsweise quadratische oder rechteckige Querschnitte. Der Rollstuhl wird daher mit massiven, steifen Elementen, nämlich den Befestigungselementen mit dem Fahrzeug verbunden.The fasteners are rod-shaped, and therefore have a long cylindrical shape, the cross-section of the fasteners can be round, but other shapes are also included, such as square or rectangular cross-sections. The wheelchair is therefore connected to the vehicle with solid, rigid elements, namely the fastening elements.
Die Befestigung erfolgt erfindungsgemäß durch eine Dreipunktbefestigung/-verankerung im Fahrzeug. Zwei Kontaktpunkte werden durch horizontal verschiebliche Befestigungselemente gebildet, der dritte Kontaktpunkt wird durch eine vertikale Stütze am Boden des Fahrzeuges gebildet.According to the invention, it is fastened by a three-point fastening/anchoring in the vehicle. Two contact points are formed by horizontally sliding fasteners, the third contact point is formed by a vertical support on the floor of the vehicle.
Bevorzugt weisen die Befestigungselemente Positionierungshilfen auf, wobei die Befestigungselemente mittels der Positionierungshilfen durch einen Benutzer des Rollstuhls axial verschiebbar sind, so dass durch den Benutzer des Rollstuhls die Befestigungselemente in die ausgefahrene Position verschoben werden können und die Kontaktpunkte am Fahrzeug befestigt werden können. Die Positionierungshilfen sind beispielsweise durch Griffe zum mechanischen Verschieben der Befestigungselemente ausgebildet, als Knopf, Erhebung, Vertiefung als raue oder geriffelte Oberfläche, oder als Kunststoffüberzug bzw. umfassen eines oder mehrere der genannten Elemente. Eine raue oder geriffelte Oberfläche kann beispielsweise dazu dienen, um die Befestigungselemente besser halten zu können. Ein Kunststoffüberzug kann beispielsweise für Befestigungselemente aus Metall dazu dienen, eine thermische Entkopplung zu im Winter kalten oder im Sommer heißen Befestigungselementen zu bilden.The fastening elements preferably have positioning aids, the fastening elements being axially displaceable by a wheelchair user using the positioning aids, so that the wheelchair user can move the fastening elements into the extended position and attach the contact points to the vehicle. The positioning aids are designed, for example, as handles for mechanically moving the fastening elements, as a knob, elevation, depression as a rough or corrugated surface, or as a plastic coating or include one or more of the elements mentioned. A rough or corrugated surface can be used, for example, to hold the fasteners better. A plastic coating can be used, for example, for metal fasteners to form a thermal decoupling from fasteners that are cold in winter or hot in summer.
Die Kontaktpunkte dienen der Befestigung der Befestigungselemente am Fahrzeug. Eine solche Befestigung kann im einfachsten Fall durch jede Anlage an einem fahrzeugfesten Bauteil gebildet sein. Bevorzugt sind die Kontaktpunkte aber für einen Halt, beispielsweise durch einen Formschluss, am Fahrzeug ausgebildet. Besonders bevorzugt weisen die Kontaktpunkte einen Verriegelungsmechanismus auf, zur Verriegelung der Befestigung der Befestigungselemente am Fahrzeug. Durch die Montage dieser Verriegelung hat der Rollstuhlfahrer die Möglichkeit den Rollstuhl selbstständig in einem Fahrzeug zu verriegeln und somit einen sicheren Sitzplatz zu schaffen.The contact points are used to attach the fasteners to the vehicle. In the simplest case, such a fastening can be formed by any system on a component fixed to the vehicle. However, the contact points are preferably designed for a hold on the vehicle, for example by means of a form fit. The contact points particularly preferably have a locking mechanism for locking the fastening of the fastening elements to the vehicle. through the assembly With this lock, the wheelchair user has the option of locking the wheelchair in a vehicle independently and thus creating a safe seat.
Bevorzugt ist der Verriegelungsmechanismus mittels der Positionierungshilfen durch den Benutzer des Rollstuhls lösbar. Der Benutzer des Rollstuhls kann somit, bevorzugt durch das Drücken oder Bewegen eines Betätigungselements, vorzugsweise angeordnet an den Positionierungshilfen, selbst den Rollstuhl wieder entriegeln.The locking mechanism can preferably be released by the user of the wheelchair by means of the positioning aids. The user of the wheelchair can thus unlock the wheelchair again himself, preferably by pressing or moving an actuating element, preferably arranged on the positioning aids.
In einer alternativen Ausführungsform können die horizontal verschieblichen Befestigungselemente teleskopartig ausgeführt sein und einen Verriegelungsmechanismus aufweisen, beispielsweise eine Verrastung, zur Fixierung der einmal eingestellten bzw. an die Verhältnisse im jeweiligen Fahrzeug angepassten Längen der Befestigungselemente.In an alternative embodiment, the horizontally displaceable fastening elements can be telescopic and have a locking mechanism, for example a catch, for fixing the lengths of the fastening elements that have been set or adapted to the conditions in the respective vehicle.
Das im Wesentlichen vertikal verschiebbare Befestigungselement wird bevorzugt durch eine vertikal ausgerichtete Teleskopstange gebildet. Eine einzelne vertikale Säule als drittes Befestigungselement kann insbesondere dann verwendet werden, wenn die Tragstruktur des Rollstuhls durch ein flächiges Bauteil, insbesondere durch ein Gehäuse, gebildet wird und wenn der Rollstuhl nicht zusammenklappbar ist.The essentially vertically displaceable fastening element is preferably formed by a vertically aligned telescopic rod. A single vertical column as a third fastening element can be used in particular when the supporting structure of the wheelchair is formed by a flat component, in particular by a housing, and when the wheelchair cannot be folded up.
Alternativ kann das im Wesentlichen vertikal verschiebbare Befestigungselement durch zwei V-förmig in Richtung zu einem gemeinsamen Kontaktpunkt hin aufeinander zulaufende Teleskopstangen gebildet wird. Diese beiden Teleskopstangen können durch eine Querverstrebung, insbesondere eine Quer-Teleskopstange, miteinander verbunden sein. An dieser Querverstrebung kann eine gemeinsame Positionierungshilfe für die beiden Teleskopstangen angeordnet sein. Eine solche Anordnung V-förmig aufeinander zulaufender Teleskopstangen kann insbesondere dann verwendet werden, wenn die Tragstruktur des Rollstuhls durch einen Rahmen gebildet wird - insbesondere, wenn der Rollstuhl zusammenklappbar ist.Alternatively, the essentially vertically displaceable fastening element can be formed by two telescopic rods running towards one another in a V-shape in the direction of a common contact point. These two telescopic rods can be connected to one another by a cross brace, in particular a transverse telescopic rod. A common positioning aid for the two telescopic rods can be arranged on this cross brace. Such an arrangement V-shaped converging telescopic rods can be used in particular when the supporting structure of the wheelchair is formed by a frame - especially when the wheelchair is collapsible.
Zumindest ein Kontaktpunkt kann einen elektrischen Lade-Anschluss aufweisen, so dass ein elektrischer Energiespeicher des Rollstuhls über den Kontaktpunkt aus einem elektrischen Energiespeicher des Fahrzeugs geladen werden kann.At least one contact point can have an electrical charging connection, so that an electrical energy store of the wheelchair can be charged via the contact point from an electrical energy store of the vehicle.
