Abstract
Bei einem Fahrzeugsitz, insbesondere Kraftfahrzeugsitz, mit wenigstens einem umlaufenden Rahmen (10) als tragender Struktur, welcher mehrere Schenkel (12, 14, 16) aufweist, wobei wenigstens ein Schenkel (12, 14, 16) des Rahmens (10) ein erstes Schenkelteil (21) und ein zweites Schenkelteil (22) aufweist, welche getrennt voneinander ausgebildet und miteinander zu einem Hohlprofil verbunden sind, wobei das erste Schenkelteil (21) und das zweite Schenkelteil (22) aus einem faserverstärktem Thermoplast geformt ist, sind die beiden Schenkelteile (21, 22) zu dem einzelnen Schenkel (12) verbunden, welcher ein leeres Hohlprofil aufweist, wobei der einzelne Schenkel (12) mit den benachbarten Schenkeln (14, 16) des Rahmens (10) verbunden ist.In a vehicle seat, in particular motor vehicle seat, with at least one circumferential frame (10) as a supporting structure, which has a plurality of legs (12, 14, 16), wherein at least one leg (12, 14, 16) of the frame (10) has a first leg portion (21) and a second leg portion (22) which are formed separately and connected to a hollow profile, wherein the first leg portion (21) and the second leg portion (22) is formed from a fiber-reinforced thermoplastic, the two leg portions ( 21, 22) connected to the single leg (12) having an empty hollow profile, wherein the single leg (12) with the adjacent legs (14, 16) of the frame (10) is connected.
Description
Die Erfindung betrifft einen Fahrzeugsitz mit den Merkmalen des Oberbegriffs des Anspruches 1.The invention relates to a vehicle seat having the features of the preamble of
Die Sitzteile und Lehnen von Fahrzeugsitzen weisen eine tragende Struktur auf, welche auf der dem Insassen des Fahrzeugsitzes zugewandten Seite ein mit einem Bezug versehenes Polster trägt. Eine übliche tragende Struktur ist ein metallischer Rahmen, beispielsweise aus Stahlblechteilen, die zu Hutprofilen und C-Profilen umgeformt und miteinander verbunden werden. Bei Sportsitzen wird als tragende Struktur oft eine Schale aus einem Faserverbundwerkstoff verwendet, welche im Verhältnis zum metallischen Rahmen ein geringeres Gewicht aufweist, aber weniger Befestigungsmöglichkeiten bietet. Um sowohl die Form und Befestigungsmöglichkeiten des Rahmens als auch das Gewicht eines Faserverbundverstoffes zu nutzen, kam die Idee auf, für den Rahmen einen Faserverbundwerkstoff zu verwenden.The seat parts and backs of vehicle seats have a load-bearing structure, which carries a pad provided with a cover on the side facing the occupant of the vehicle seat. A common load-bearing structure is a metallic frame, for example made of sheet steel parts, which are converted into hat profiles and C-profiles and connected together. In sports seats, a shell of a fiber composite material is often used as a supporting structure, which has a lower weight in relation to the metallic frame, but offers less mounting options. In order to use both the shape and mounting options of the frame and the weight of a fiber composite, the idea came up to use a fiber composite for the frame.
So wird in der
Der Erfindung liegt die Aufgabe zu Grunde, einen Fahrzeugsitz der eingangs genannten Art zu verbessern. Diese Aufgabe wird erfindungsgemäß durch einen Fahrzeugsitz mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.The invention is based on the object to improve a vehicle seat of the type mentioned. This object is achieved by a vehicle seat with the features of
Indem beide Schenkelteile aus einem faserverstärktem Thermoplast (”Organoblech”) geformt sind, stehen die Vorteile dieses Materials auf allen Seiten des betreffenden Schenkels zur Verfügung. Insbesondere reduziert dieses Material das Gewicht gegenüber Metall um 10% und mehr. Das leere Hohlprofil bietet gegenüber dem gefüllten Hohlprofil den Vorteil des geringeren Gewichts. Dadurch, dass die beiden Schenkelteile zu einem einzelnen Schenkel verbunden werden, steht gegenüber dem Rahmen mit einstückig miteinander ausgebildeten Schenkeln die Möglichkeit zur Verfügung, Schenkel aus einem faserverstärkten Thermoplast einerseits und Schenkel aus Metall andererseits miteinander zu kombinieren, also beispielsweise Traversen und Holme aus unterschiedlichen Materialen zu verwenden.By forming both leg parts from a fiber reinforced thermoplastic ("organo sheet"), the benefits of this material are available on all sides of the leg concerned. In particular, this material reduces the weight over metal by 10% or more. The empty hollow profile offers over the filled hollow profile the advantage of less weight. Characterized in that the two leg portions are connected to a single leg, is opposite the frame with integrally formed legs the possibility to combine legs of a fiber-reinforced thermoplastic on the one hand and legs of metal on the other hand with each other, so for example trusses and spars made of different materials to use.
Funktionsbereiche des Rahmens, insbesondere seine Befestigungsbereiche und die Befestigungsbereiche für weitere Bauteile, können an den Schenkelteilen angeformt oder eingeschnitten werden. An eingeschnittenen Aussparungen können die Belastungen durch Verstärkungen verringert werden. Das Hohlprofil ist vorzugsweise aus einem Hutprofil und einem Flachprofil kombiniert.Functional areas of the frame, in particular its attachment areas and the attachment areas for further components, can be formed or cut on the leg portions. Cut recesses can reduce the stress caused by reinforcements. The hollow profile is preferably combined from a hat profile and a flat profile.
Das Verbinden der Schenkelteile miteinander und des einzelnen Schenkels mit den benachbarten Schenkeln erfolgt vorzugsweise mittels Kleben. Zur Vorpositiierung oder als Verbindung während des Aushärtens des Klebstoffes können Befestigungsmittel, wie Niete, Schrauben, Klammern, Clips oder dergleichen vorgesehen sein. Die thermoplastischen Teile können auch durch Ultraschall oder Erwärmung und Anpressen verbunden werden. Ein Formschluss kann der Vorpositionierung und dem Schutz der Verbindung dienen, insbesondere im Falle des Klebens.The joining of the leg parts with each other and the single leg with the adjacent legs is preferably done by gluing. For pre-initiating or bonding during curing of the adhesive, fasteners such as rivets, screws, staples, clips or the like may be provided. The thermoplastic parts can also be connected by ultrasound or heating and pressing. A positive connection can serve the pre-positioning and the protection of the connection, in particular in the case of gluing.
Es können ein einziger oder mehrere Schenkel des Rahmens aus dem faserverstärktem Thermoplast bestehen. Der Rahmen kann als tragende Struktur der Lehne oder des Sitzteils oder an einer anderen Stelle des Fahrzeugsitzes dienen.There may be a single or multiple legs of the frame of the fiber reinforced thermoplastic. The frame may serve as a supporting structure of the backrest or the seat part or at another location of the vehicle seat.
