Description
Die vorliegende Erfindung betrifft eine Befestigungsvorrichtung zur lösbaren Befestigung eines Rollstuhls in einem Fahrzeug.The present invention relates to a fastening device for releasably fastening a wheelchair in a vehicle.
In Personenbeförderungseinrichtungen wie Bussen ist die Verwendung von Befestigungselementen zur Befestigung von Rollstühlen während der Fahrt bekannt. Insbesondere werden Gurte verwendet, um einen Rollstuhl beispielsweise an einer Wand oder im Bodenbereich des Fahrzeuges zu befestigen.In passenger transportation devices such as buses, the use of fastening elements for fastening wheelchairs while driving is known. In particular, belts are used to attach a wheelchair, for example, to a wall or in the floor area of the vehicle.
Beispielsweise offenbart die
Problematisch an bekannten Rollstuhlbefestigungen ist, dass die Rollstühle selbst und auch die Befestigungselemente oft nicht stabil genug sind, um die Benutzer eines Rollstuhls bei einem Unfall des Beförderungsfahrzeuges ausreichend zu sichern. Außerdem haben Rollstuhlfahrer oft keine Möglichkeit Ihren Rollstuhl selbständig im Fahrzeug zu verankern.The problem with known wheelchair fastenings is that the wheelchairs themselves and also the fastening elements are often not stable enough to adequately secure the users of a wheelchair in the event of an accident in the transport vehicle. In addition, wheelchair users often have no way of anchoring their wheelchair independently in the vehicle.
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 provide 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 in the event of an accident in the vehicle. It should also be possible for a wheelchair user to attach the wheelchair themselves.
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.The object is achieved by a fastening device for releasably fastening a wheelchair in a vehicle, comprising a mechanically stable supporting 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 axially displaceably connected to the support structure and at a second end opposite the first end contact points are formed for fastening in the vehicle, the fastening elements being designed to be axially displaced by a user of the wheelchair, so that the fastening elements can be moved into the extended position by the user of the wheelchair and the contact points can be attached to 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 fastening 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 to this support structure at least indirectly, in such a way that the essentially rod-shaped fastening elements can be pushed axially back and forth. A free end of a fastening element, the second end, is used for fastening to the vehicle. The other, first end of the fastener remains connected to the support structure even in the extended state and thus when the wheelchair is attached 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 wheelchair user even in the event of an accident. The fastening elements are axially displaceable by a user of the wheelchair itself and can therefore be displaced into the extended and fastened state by the user. For this purpose, the fastening elements are mounted in an axially displaceable manner in a suitable manner, so that an occurring force is conducted through the support 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 required support structure or an existing support structure on the wheelchair can be used for the fastening 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 fastening elements are rod-shaped and therefore have a long cylindrical shape, the cross section of the fastening elements 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.
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 user of the wheelchair by means of the positioning aids, so that the fastening elements can be moved into the extended position by the user of the wheelchair and the contact points can be fastened to the vehicle. The positioning aids are, for example, handles for mechanical displacement of the fasteners formed as a button, elevation, depression as a rough or corrugated surface, or as a plastic coating or comprise one or more of the elements mentioned. A rough or corrugated surface can be used, for example, to better hold the fasteners. A plastic cover can serve, 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 formed on the vehicle for a hold, for example by a positive fit. The contact points particularly preferably have a locking mechanism for locking the fastening of the fastening elements on the vehicle. By installing this lock, the wheelchair user can lock the wheelchair in a vehicle independently and thus create 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, preferably by pressing or moving an actuating element, preferably arranged on the positioning aids.
Vorzugsweise umfasst die Befestigungsvorrichtung zumindest drei der im Wesentlichen stangenförmigen Befestigungselemente, wovon zwei Befestigungselemente im Wesentlichen horizontal verschiebbar sind, zur Befestigung des Rollstuhls an einem vertikalen Element des Fahrzeugs, beispielsweise an einer Wand, an einer Säule oder an einer vertikalen Fläche eines Sitzes, und ein Befestigungselement im Wesentlichen vertikal verschiebbar ist, zur Befestigung des Rollstuhls an einem Boden des Fahrzeugs.The fastening device preferably comprises at least three of the essentially rod-shaped fastening elements, of which two fastening elements can be displaced essentially horizontally, for fastening the wheelchair to a vertical element of the vehicle, for example on a wall, on a column or on a vertical surface of a seat, and one Fastening element can be moved essentially vertically for fastening the wheelchair to a floor of the vehicle.
Die Befestigung erfolgt somit bevorzugt 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. 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.The attachment is thus preferably carried out by a three-point attachment / anchoring in the vehicle. Two contact points are formed by horizontally displaceable fastening elements, the third contact point is formed by a vertical support on the floor of the vehicle. In an alternative embodiment, the horizontally displaceable fastening elements can be designed telescopically and have a locking mechanism, for example a latching mechanism, 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 oriented telescopic rod. A single vertical column as a third fastening element can be used in particular when the support structure of the wheelchair is formed by a flat component, in particular by a housing, and when the wheelchair is not collapsible.
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 V-shaped telescopic rods tapering towards one another in the direction of a common contact point. These two telescopic rods can be connected to one another by a cross strut, in particular a transverse telescopic rod. A common positioning aid for the two telescopic rods can be arranged on this cross strut. Such an arrangement of V-shaped telescopic rods can be used in particular if the support structure of the wheelchair is formed by a frame - in particular if 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.
