Der Erfindung liegt die Aufgabe zu Grunde, ein verbessertes Stellelement anzugeben.The invention is based on the object to provide an improved actuator.
Die Aufgabe wird erfindungsgemäß gelöst durch ein Stellelement mit den Merkmalen des Anspruchs 1.The object is achieved by an actuator with the features of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Ein Stellelement umfasst zumindest eine zur Konturverstellung eines Fahrzeugsitzes mit einem Fluid befüllbare Blase (insbesondere Sitzblase), welche wenigstens zwei Blasenwände aufweist, wobei die Blasenwände randseitig zumindest bereichsweise mittels zumindest einer Schweißnaht fluiddicht miteinander verbunden sind.An actuator comprises at least one for filling the contour of a vehicle seat with a fluid-filled bladder (in particular seat bladder), which has at least two bladder walls, wherein the bladder walls are at least partially connected fluid-tightly at least partially by means of at least one weld.
Erfindungsgemäß ist in einem durch die Blasenwände gebildeten Innenraum der Blase zumindest ein Federring angeordnet, welcher umlaufend an einem Verbindungsbereich der miteinander verbundenen Blasenwände anliegt.According to the invention, at least one spring ring is arranged in an inner space of the bladder formed by the bladder walls, which circumferentially abuts against a connecting region of the interconnected bladder walls.
Die Blasenwände sind zweckmäßigerweise nicht vollumfänglich miteinander verschweißt, d. h. es bleibt zweckmäßigerweise eine Öffnung erhalten, durch welche die Blase mit dem Fluid befüllbar und wieder entleerbar ist. Alternativ kann die Öffnung auch in einer der Blasenwände angeordnet sein.The bladder walls are expediently not completely welded together, d. H. it remains expediently obtained an opening through which the bladder can be filled with the fluid and emptied again. Alternatively, the opening may also be arranged in one of the bladder walls.
Der Federring ermöglicht eine Stützung des Verbindungsbereiches der durch die Schweißnaht miteinander verbundenen Blasenwände, wodurch Undichtigkeiten der Blase aufgrund von Ermüdungsbrüchen der Schweißnaht oder der Blasenwände im Bereich der Schweißnaht verhindert oder zumindest deutlich reduziert sind. Derartige Ermüdungsbrüche treten bei Sitzblasen nach dem Stand der Technik auf, da die Blasenwände während der Herstellung plan aufeinander zu legen und in diesem planen Zustand miteinander zu verschweißen sind. Bei Druckbeaufschlagung durch eine dreidimensionale Ausdehnung der Sitzblase, d. h. durch ein Aufwölben der Blasenwände, bewegen sich Randbereiche der Blasenwände und dadurch auch der Schweißnahtbereich in Richtung eines Sitzblasenmittelpunktes, wodurch sich im Bereich der Schweißnaht Falten, Knickungen und/oder Einschnürungen der relativ steifen Schweißnaht ausbilden. Bei häufiger Druckbeaufschlagung und Druckentlastung führt dies zu den Ermüdungsbrüchen der Schweißnaht oder der Blasenwände.The spring ring enables a support of the connection region of the bladder walls connected to one another by the weld seam, whereby leaks in the bladder due to fatigue fractures of the weld or the bladder walls in the region of the weld seam are prevented or at least significantly reduced. Such fatigue fractures occur in seat bladders according to the prior art, since the bladder walls are flat during manufacture and are to be welded together in this planar state. When pressurized by a three-dimensional expansion of the seat bladder, d. H. by a bulging of the bladder walls, edge regions of the bladder walls and thereby also the weld seam area move in the direction of a seat bladder center, whereby folds, bends and / or constrictions of the relatively stiff weld seam are formed in the region of the weld seam. With frequent pressurization and pressure relief, this leads to the fatigue fractures of the weld or the bladder walls.
Durch den Federring sind derartige unvorteilhafte Verformungen der Schweißnaht vermieden oder zumindest deutlich reduziert, wodurch auch Ermüdungsbrüche und daraus resultierende Leckagen vermieden oder zumindest deutlich reduziert sind. Insbesondere sind durch die gleichmäßig über den Verbindungsbereich verteilte Stützwirkung des Federrings extreme, d. h. besonders große Verformungen, zum Beispiel in Form von Knickstellen vermieden, da eine Kontur des Verbindungsbereichs der Blasenwände durch den Federring ständig unter Spannung gehalten ist. Auf diese Weise bildet sich eine Vielzahl von relativ gleichmäßig verteilten kleinen Knickstellen aus, welche für eine Stabilität der Schweißnaht und der Blasenwände ungefährlich sind. Da hierzu außer dem kastengünstigen Federring keine weiteren zusätzlichen Hilfsmittel und auch kein aufwändigeres Herstellungsverfahren erforderlich sind, ist auf diese Weise bei gleich bleibenden Kosten eine wesentlich verbesserte Dauerhaltbarkeit der Sitzblase und dadurch des Stellelementes erreicht.By the spring ring such unfavorable deformations of the weld are avoided or at least significantly reduced, whereby fatigue fractures and resulting leaks are avoided or at least significantly reduced. In particular, by the evenly distributed over the connection area supporting effect of the spring ring extreme, d. H. particularly large deformations, for example in the form of kinks avoided because a contour of the connecting portion of the bladder walls is held by the spring ring constantly under tension. In this way, a large number of relatively evenly distributed small kinks are formed, which are harmless for stability of the weld and the bladder walls. Since this no further additional aids and no elaborate manufacturing process are required in addition to the box-elastic spring ring, a much improved durability of the seat bladder and thereby of the control element is achieved in this way at a constant cost.
