Description
Die vorliegende Erfindung betrifft eine Befestigungsvorrichtung für einen Gurtbeschlag von Sicherheitsgurten in Kraftfahrzeugen gemäß dem Oberbegriff des Patentanspruches 1.The present invention relates to a fastening device for a belt fitting of safety belts in motor vehicles according to the preamble of
Eine gattungsgemäße Befestigungsvorrichtung beschreibt die
Aufgabe der Erfindung ist es, eine Befestigungsvorrichtung für einen Gurtbeschlag von Sicherheitsgurten vorzuschlagen, die bei einer zuverlässigen und hohe Zugmomente aufnehmenden Konstruktion einfacher und montagegünstiger ausgebildet ist.The object of the invention is to propose a fastening device for a Gurtbeschlag of safety belts, which is formed in a reliable and high tensile moments receiving construction simpler and easier to install.
Die Lösung dieser Aufgabe gelingt erfindungsgemäß mit den Merkmalen des Patentanspruches 1. Vorteilhafte und besonders zweckmäßige Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.The solution of this object is achieved according to the invention with the features of
Erfindungsgemäß wird vorgeschlagen, dass die Schraube über den Kopf mit der Verankerungswand, insbesondere einem Unterboden, des Kraftfahrzeuges mittelbar oder vorzugsweise unmittelbar verschweißt ist. Das Anschweißen des Kopfes der Schraube kann bei der Rohbaufertigung des Kraftfahrzeuges erfolgen und ermöglicht sodann eine äußerst einfache Montage, indem der Gurtbeschlag lediglich auf die Schraube aufzustecken und mit der Mutter zu befestigen ist. Dies ist insbesondere von Vorteil bei Doppelgurtbeschlägen an hinteren Sitzen von Kraftfahrzeugen, an denen zwei Sicherheitsgurte angebunden sind, weil hier durch die schlechtere Zugänglichkeit der Befestigungsvorrichtung eine schnellere und einfachere Montage gegeben ist.According to the invention it is proposed that the screw via the head with the anchoring wall, in particular an underbody of the motor vehicle indirectly or preferably is welded directly. The welding of the head of the screw can be done in the shell production of the motor vehicle and then allows an extremely simple installation by the strap fitting is simply aufzustecken on the screw and fastened with the mother. This is particularly advantageous in Doppelgurtbeschlägen rear seats of motor vehicles, where two belts are connected, because here is given by the poorer accessibility of the fastening device faster and easier installation.
Gemäß einer besonders bevorzugten Ausgestaltung der vorliegenden Erfindungsidee ist hierbei vorgesehen, dass der Kopf der Schraube im Bereich seiner Auflagefläche an der Verankerungswand eine randseitige, wenigstens bereichs- oder abschnittsweise umlaufende Abstufung oder Ausnehmung aufweist, die im montierten Zustand der Schraube zwischen der Anlagefläche und der Verankerungswand eine Schweißnut ausbildet, in die das Schweißgut beim Aufbringen einer Schweißnaht eindringen kann. Mittels einer derartigen Schweißverbindung wird eine besonders stabile und funktionssichere Anbindung des Schraubenkopfes und damit der gesamten Schraube an der Verankerungswand sichergestellt, und zwar ohne eine wesentliche Beeinträchtigung der flächigen Anlageverbindung des Schraubenkopfes mittels seiner Auflagefläche an der Verankerungswand.According to a particularly preferred embodiment of the present invention idea is provided here that the head of the screw in the region of its support surface on the anchoring wall has an edge-side, at least partially or sectionally circumferential gradation or recess in the assembled state of the screw between the contact surface and the anchoring wall forms a weld groove, in which the weld metal can penetrate when applying a weld. By means of such a welded connection a particularly stable and reliable connection of the screw head and thus the entire screw is secured to the anchoring wall, without a significant impairment of the flat contact connection of the screw head by means of its bearing surface on the anchoring wall.
Besonders bevorzugt ist hierbei eine Schraubenkopfausgestaltung, bei dem die Auflagefläche des Schraubenkopfes bezogen auf die Querschnittsfläche des Gewindebolzens sehr groß ist, um durch die größere Auflagefläche des Kopfes der Schraube eine zuverlässige, hohe Zugmomente aufnehmende Befestigung sicherzustellen. Insbesondere kann die Auflagefläche des Kopfes der Schraube mindestens das Fünffache der Querschnittsfläche des Gewindebolzens betragen, wodurch zusätzliche Verstärkungsbleche unterhalb der Verankerungswand bzw. des Unterbodens gegebenenfalls gänzlich entfallen können.Particularly preferred in this case is a screw head design, in which the bearing surface of the screw head relative to the cross-sectional area of the threaded bolt is very large in order to ensure a reliable, high tensile moments receiving fastening by the larger bearing surface of the head of the screw. In particular, the bearing surface of the head of the screw can amount to at least five times the cross-sectional area of the threaded bolt, whereby additional reinforcing plates below the anchoring wall or the subfloor may possibly be completely eliminated.
Fertigungstechnisch besonders günstig kann der Kopf der Schraube als rotationssymmetrische Scheibe gestaltet sein, deren Durchmesser bevorzugt zumindest das Dreifache des Durchmessers des Gewindebolzens beträgt, um eine großflächige Kopf-Auflagefläche mit den zuvor erwähnten Vorteilen auszubilden.In terms of manufacturing technology, the head of the screw can be designed as a rotationally symmetrical disk whose diameter is preferably at least three times the diameter of the threaded bolt in order to form a large-area head bearing surface with the advantages mentioned above.
Schließlich kann die Schraube an ihrem freien Ende einen im Durchmesser verminderten Fortsatz als Auffädelhilfe für die aufzuschraubende Mutter aufweisen. Mit dieser einfachen Maßnahme kann bei einer schlechten Zugänglichkeit der Befestigungsvorrichtung eine weitere Montagevereinfachung erzielt werden.Finally, the screw may have at its free end a reduced diameter extension as Auffädelhilfe for the nut to be screwed. With this simple measure a further accessibility can be achieved with poor accessibility of the fastening device.
Gemäß einer weiteren besonders bevorzugten Ausgestaltung der vorliegenden Erfindungsidee kann im Bereich des Gewindebolzens wenigstens eine Schabenut ausgebildet sein, wobei insbesondere vorgesehen ist, dass mehrere in Gewindebolzenumfangsrichtung beabstandete und in Gewindebolzenlängsrichtung verlaufende Schabenuten im Bereich des Gewindebolzens ausgebildet sind. Mit einer derartigen Schabenut wird, insbesondere in Verbindung mit aufgebrachten Beschichtungen, wie zum Beispiel KTL-Beschichtungen und Lackbeschichtungen im Gewindebereich sichergestellt, dass das jeweilige Gewinde freigeschabt wird und in seiner Funktion nicht beeinträchtigt wird.According to a further particularly preferred embodiment of the present inventive concept, at least one cockroach groove may be formed in the region of the threaded bolt, wherein it is provided in particular that a plurality of scraping grooves spaced in the threaded bolt circumferential direction and extending in the threaded bolt longitudinal direction are formed in the region of the threaded bolt. With such a scraping groove, in particular in conjunction with applied coatings, such as, for example, KTL coatings and lacquer coatings in the thread area, it is ensured that the respective thread is scraped free and is not impaired in its function.
