Der Erfindung liegt die Aufgabe zu Grunde, ein verbessertes Stellelement und ein verbessertes Verfahren zur Herstellung eines Stellelementes anzugeben.The invention is based on the object to provide an improved control element and an improved method for producing an actuating element.
Die Aufgabe wird erfindungsgemäß gelöst durch ein Stellelement mit den Merkmalen des Anspruchs 1 und ein Verfahren zur Herstellung eines Stellelementes mit den Merkmalen des Anspruchs 6.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 Sitzblase, welche wenigstens zwei Blasenwände aufweist, wobei die Blasenwände randseitig zumindest bereichsweise mittels zumindest einer Schweißnaht fluiddicht miteinander verbunden sind.An actuating element comprises at least one seat bladder which can be filled with a fluid for contour adjustment of a vehicle seat and has at least two bladder walls, wherein the bladder walls are connected to one another at least in regions in a fluid-tight manner by means of at least one weld seam.
Erfindungsgemäß ist ein Konturverlauf der zumindest einen Schweißnaht belastungsangepasst ausgebildet, wobei die Anpassung des Konturverlaufs an die Belastung durch empirische Untersuchungen, numerisch über Simulationen und/oder analytisch über Berechnungen bestimmt ist.According to the invention, a contour curve of the at least one weld seam is designed to be load-adapted, wherein the adaptation of the contour profile to the load is determined by empirical investigations, numerically by means of simulations and / or analytically by calculations.
Das Verschweißen der Blasenwände erfolgt zweckmäßigerweise nicht vollumfänglich, d. h. es bleibt zweckmäßigerweise eine Öffnung, durch welche die Sitzblase mit dem Fluid befüllbar und wieder entleerbar ist, erhalten. Alternativ kann die Öffnung auch in einer der Blasenwände angeordnet sein.The welding of the bladder walls is expediently not fully, d. H. it remains expediently an opening through which the seat bladder with the fluid can be filled and emptied again received. Alternatively, the opening may also be arranged in one of the bladder walls.
Durch die erfindungsgemäße Ausbildung des Konturverlaufs der Schweißnaht sind Undichtigkeiten der Sitzblase aufgrund von Ermüdungsbrüchen der Schweißnaht oder der Blasenwände im Bereich der Schweißnaht verhindert oder zumindest deutlich reduziert. 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 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.Due to the inventive design of the contour of the weld seam leaks of the seat bubble due to fatigue fractures of the weld or the bladder walls in the region of the weld 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 to be welded together in this flat 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 area of the weld seam. With frequent pressurization and pressure relief, this leads to the fatigue fractures of the weld or the bladder walls.
Durch die erfindungsgemäße Ausbildung des Konturverlaufs der Schweißnaht sind derartige unvorteilhafte Verformungen der Schweißnaht vermieden oder zumindest deutlich reduziert, wodurch auch Ermüdungsbrüche und daraus resultierende Leckagen vermieden oder zumindest deutlich reduziert sind. Da hierzu keine 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.The inventive design of the contour of the weld seam 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. Since this no additional tools and no complex manufacturing process are required, a much improved durability of the seat bladder and thereby the actuator is achieved in this way at constant cost.
