Abstract
Description
Die Erfindung betrifft ein Bauelement mit aktiv formveränderbarem Raumprofil, welches zum Beispiel im Fahrzeugbau für Karosserie- oder Innenraumelemente eingesetzt werden kann.The invention relates to a component with actively changeable shape Room profile, which is used for example in or interior elements can be used.
Bauelemente mit aktiv formveränderbarem Raumprofil werden zum Beispiel als Airbags in Kraftfahrzeugen angewendet. Diese umfassen eine fluiddichte Hüllmembran sowie eine Überdruck erzeugende Fluidquelle, die mit dem Inneren der Hüllmembran in fluiddichter Verbindung steht. Im Ausgangszustand haben die Airbags ein relativ geringes Volumen und sind in unauffälliger Weise vor oder neben den Fahrzeuginsassen installiert. Im Falle von außerordentlichen Stoßeinwirkungen auf das Fahrzeug, zum Beispiel bei Auffahrunfällen, seitlichen Kollisionen oder dergleichen wird die Fluidquelle aktiviert, und die fluiddichte Hüllmembran des Airbags wird innerhalb kürzester Zeit zu einem relativ großen Polsterkörper mit einem vorbestimmten Raumprofil umgeformt, welcher die Körper der Fahrzeuginsassen vor dem Zusammenprall mit harten und kantigen Körpern und damit vor Verletzungen bewahren soll.Components with an actively shape-changing room profile are used, for example, as airbags in motor vehicles. This comprise a fluid-tight envelope membrane as well as an overpressure generating fluid source that is in with the interior of the envelope membrane there is a fluid-tight connection. In the initial state, the airbags have a relatively small volume and are inconspicuously in front of or next to the vehicle occupants installed. In the case of extraordinary impacts on the vehicle, for example in collisions, side collisions or the like, the fluid source is activated and the fluid tight envelope membrane the airbag will be within shortest Time to a relatively large Upholstered body with formed a predetermined spatial profile, which the body of the Vehicle occupants from collision with hard and angular bodies and thus should protect against injuries.
Für diesen speziellen Einsatzfall als lebensrettendes Polster ist dieses als Airbag bekannte Bauelement mit aktiv formveränderbarem Raumprofil ausgezeichnet geeignet. Es hat jedoch den Nachteil, dass es im aktivierten Zustand nur ein definiertes Raumprofil aufweist, und dass dessen Anordnung im Raum nicht definiert ist. Auch handelt es sich bei der Formveränderung des Airbag um einen irreversiblen Vorgang. Für viele Einsatzfälle, bei denen eine mehrfache und reversible Formveränderung des Bauelementes erwünscht ist, und bei welchem es auf eine definierte Anordnung des Bauelementes in einer bestimmten Lage ankommt, erweist sich dieses bekannte Bauelement mit aktiv formveränderbarem Raumprofil als ungeeignet. Zum Beispiel kann eine Veränderung der äußeren Form von Karosserieteilen von Kraftfahrzeugen mit dem Ziel der vorübergehenden Anpassung ihres aerodynamischen Verhaltens an höhere Geschwindigkeiten mit der vom Airbag bekannten Struktur eines Bauelementes mit aktiv formveränderbarem Raumprofil nicht realisiert werden.For this special application as a life-saving cushion is this Awarded component known as an airbag with an actively shape-changing room profile suitable. However, it has the disadvantage that it is activated only has a defined spatial profile, and that its arrangement is not defined in space. The change in shape is also involved the airbag to an irreversible process. For many applications, at where a multiple and reversible change in shape of the component is desired, and in which it is based on a defined arrangement of the component arrives in a certain position, this well-known component proves with actively changing room profile as unsuitable. For example, a change in the external shape of body parts of motor vehicles with the aim of temporary Adaptation of their aerodynamic behavior to higher speeds with the structure of a component known from the airbag with an actively changeable shape Room profile cannot be realized.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Bauelement mit aktiv formveränderbarem Raumprofil zu schaffen, welches in verschiedenen Formzuständen jeweils definierte räumliche Konturen und eine stabile Lage im Raum aufweist, und bei welchem die Formveränderungen reversibel sind.The invention is therefore the object based on creating a component with an actively shape-changing spatial profile, which defines spatial in different shape states Contours and a stable position in the room, and in which the shape changes are reversible.
