Description
Die Erfindung betrifft ein Bauteil zur Befestigung eines Bezuges auf der Polsterung eines Sitzes, wobei ein Schaft an einem Ende hakenförmig ausgebildet ist und am anderen Ende eine Scheibe trägt.The invention relates to a component for fastening a Cover on the upholstery of a seat, with a shaft attached is hook-shaped at one end and at the other end carries a disc.
Bei Automobilsitzen wird - wie auch meist bei Sitzmöbeln - der Bezug straff über die Polsterung gespannt. Dazu ist im Falle von Autositzen der Bezug mit Leinenschlaufen und Drähten versehen, welche in durch die Polsterung gesteckte Einhängehaken eingehakt werden. Die Einhängehaken sind auf der dem Bezug gegenüberliegenden Seite der Polsterung mit einer Scheibe versehen. Beim Einhängen der Drähte in die Haken ist eine Kraft erforderlich, welche die Steifigkeit der Polsterung überwindet. Damit der Haken beim Einhängevorgang nicht nachgibt, ist eine entsprechende auf die Scheibe wirkende Gegenkraft bei dem Montagevorgang erforderlich. Derartige Sitzbefestiger sind beispielsweise aus dem Katalog "Befestigungstechnologie" der MECANO RAPID GmbH, Oktober 1995, Seite 66 bekannt. In automotive seats - as is usually the case with seating furniture - the cover is stretched tight over the upholstery. This is in Case of car seats the cover with linen loops and Provide wires that are inserted through the padding Hooks can be hooked. The hooks are open the side of the upholstery opposite the cover a disc. When hanging the wires in the A hook force is required which is the rigidity the padding overcomes. So that the catch with Hooking process does not give way, a corresponding one is on the disc acting counterforce during the assembly process required. Such seat fasteners are, for example from the MECANO RAPID "fastening technology" catalog GmbH, October 1995, page 66.
Aufgabe der vorliegenden Erfindung ist es, ein Bauteil zur Befestigung eines Bezuges auf der Polsterung eines Sitzes anzugeben, in dessen Einhängehaken Schlaufen oder Drähte des Bezuges ohne weiteres Fixieren des Bauteils eingehängt werden können.The object of the present invention is to provide a component for Attaching a cover to the upholstery of a seat specify in the hooks loops or wires of the Cover attached without further fixation of the component can be.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Schaft radial vorstehende Haltearm aufweist, die jeweils nur einen Teil des Umfangs einnehmen.This object is achieved in that the Shaft has radially protruding holding arm, each only occupy part of the circumference.
Außer der dadurch vereinfachten Montage hat das erfindungsgemäße Bauteil den Vorteil, daß es fest in der Polsterung sitzt und somit beispielsweise bereits vom Hersteller der Polsterung eingefügt und an den Ort des Zusammenbaus mit den übrigen Teilen des Sitzes transportiert werden kann. Zum Einsetzen des erfindungsgemäßen Bauteils in die Polsterung ist die Polsterung mit einem Loch zu versehen, dessen Querschnitt ein Einführen des Bauteils derart erlaubt, daß die Haltearme in entsprechende Erweiterungen des Loches passen und daß beim Drehen des Bauteils die Haltearme in die Polsterung zwischen den Erweiterungen eindringen.In addition to the simplified assembly that has Component according to the invention the advantage that it is firmly in the Upholstery sits and thus, for example, from Manufacturer of the upholstery inserted and to the place of Assembled with the rest of the seat can be. To insert the component according to the invention in the upholstery is the upholstery with a hole too provided, the cross section of an insertion of the component allowed such that the holding arms in corresponding Extensions of the hole fit and that when turning the Part of the holding arms in the padding between the Penetrate extensions.
Wenn gemäß einer Weiterbildung der Erfindung die Haltearme in Umfangsrichtung schräg verlaufen, wird beim Drehen das Bauteil fest in die Polsterung hineingezogen.If, according to a development of the invention, the holding arms run obliquely in the circumferential direction, that is when turning Component firmly drawn into the upholstery.
Vorzugsweise ist bei dem erfindungsgemäßen Bauteil vorgesehen, daß der Schaft zweiseitig abgeflacht ist und an den nicht abgeflachten Bereichen des Umfangs die Haltearme angeordnet sind. Für dieses Bauteil wird in der Polsterung lediglich ein Langloch benötigt. An sich können bei dem erfindungsgemäßen Bauteil je nach Anwendung im einzelnen mehr oder weniger Haltearme angeordnet sein. Bei den üblicherweise verwendeten Polsterungen hat sich jedoch als vorteilhaft herausgestellt, daß an einer Seite zwei und an der anderen Seite drei Haltearme angeordnet sind.Preferably, the component according to the invention provided that the shaft is flattened on two sides and on the non-flattened areas of the circumference the holding arms are arranged. For this component is in the upholstery only one slot needed. In itself, the Component according to the invention depending on the application in detail more or less arms are arranged. Both Upholstery commonly used, however, has proven to be advantageously found that two on one side and the other side three holding arms are arranged.
Ein leichteres Eindringen der Haltearme in die Polsterung wird bei einer Weiterbildung des erfindungsgemäßen Bauteils dadurch ermöglicht, daß jeweils die in einer vorgegebenen Drehrichtung vorlaufenden Kanten der Haltearme abgerundet sind.Easier penetration of the holding arms into the upholstery is in a further development of the component according to the invention thereby enables that each in a predetermined Direction of rotation rounded edges of the holding arms are.
Ein unerwünschtes Zurückdrehen kann bei dieser Weiterbildung dadurch erschwert werden, daß die Haltearme an der in der Drehrichtung nachlaufenden Kante stumpf enden.An unwanted turning back can occur with this training are complicated by the fact that the holding arms on the in End of rotation trailing edge blunt.
Eine vorteilhafte Ausgestaltung des erfindungsgemäßen Bauteils besteht darin, daß die Haltearme ein unterbrochenes Gewinde darstellen. Zur Erleichterung der Montage des erfindungsgemäßen Bauteils kann vorgesehen sein, daß die Scheibe in Umfangsrichtung teilweise rund und teilweise derart geformt ist, daß eine Drehrichtung erkennbar ist.An advantageous embodiment of the invention Component is that the holding arms are interrupted Represent threads. To facilitate the assembly of the Component according to the invention can be provided that the Disk partly round and partially circumferential is shaped such that a direction of rotation can be seen.
Ferner kann bei dem erfindungsgemäßen Bauteil vorgesehen sein, daß der Schaft einschließlich der Scheibe eine mehrkantige Längsbohrung aufweist. In diese Längsbohrung kann ein Werkzeug zum Einsetzen und Drehen des Bauteils eingeführt werden.Furthermore, can be provided in the component according to the invention be that the shaft including the disc one has polygonal longitudinal bore. In this longitudinal hole can be a tool for inserting and rotating the component be introduced.
