Abstract

The vehicle seat has a frame consisting of a rectangular seat support (2) and a rectangular back rest section (1) these are connected by two T-section rails (4) on the back which slide in C-section rails (3) on the seat. The rails form sections of a circle whose center is positioned in the waist area of a user.

Description

Die Erfindung betrifft einen Sitz für Kraftfahrzeuge unter Verwendung eines Grundgerüstes und einer Bespannung.The The invention relates to a seat for Motor vehicles using a skeleton and a stringing.

Aus US 3 860 287 ist ein derartiger Sitz bekannt, wobei die Bespannung aus einem Drahtnetz besteht.Out US Pat. No. 3,860,287 is such a seat known, the fabric consists of a wire mesh.

Aus US 6 302 487 ist ein Sitz für Kraftfahrzeuge bekannt, bei dem auf einem Grundgerüst eine hängematteähnliche Anordnung vorgesehen ist.Out US 6,302,487 is a seat for motor vehicles is known in which a hammock-like arrangement is provided on a skeleton.

Bei derartigen Sitzen ist, wie in 1 dargestellt, der Drehpunkt zwischen Rückenlehne und Sitzpolster zwangsläufig hinter dem Hüftbereich 20 des Passagiers angeordnet. Dadurch ergibt sich eine ergonomisch ungünstige Klappbewegung der Rückenlehne. Wünschenswert wäre, die Rückenlehne bei ihrer Neigungsverstellung um eine Achse klappen zu lassen, die etwa im Hüftbereich des Passagiers liegt. Dazu wird erfindungsgemäß vorgeschlagen, dass zwischen Rückenteil und Sitz, wie in 2 schematisch dargestellt, eine formschlüssige Verbindung besteht, die auf einem Kreisbogensegment relativ zueinander verschiebbar ist, wobei der Mittelpunkt des Kreisbogensegmentes etwa im Bereich des Hüftgelenkes eines Passagiers liegt. Statt eines Kreisbogensegmentes können auch zwei oder mehrere, die Kreisform annähernde Kurven- oder Geradenstücke eingesetzt werden.In such seats is, as in 1 shown, the pivot point between the backrest and seat cushion inevitably behind the hip area 20 arranged by the passenger. This results in an ergonomically unfavorable folding movement of the backrest. It would be desirable to let the backrest tilt at its inclination adjustment about an axis which is approximately in the hip area of the passenger. For this purpose, the invention proposes that between back and seat, as in 2 shown schematically, a positive connection is made, which is displaceable relative to each other on a circular arc segment, wherein the center of the circular arc segment is located approximately in the region of the hip joint of a passenger. Instead of a circular arc segment and two or more, the circular shape approaching curve or straight line pieces can be used.

Bevorzugt ist gemäß 3 in dem Sitz eine hängemattenähnliche Bespannung 5 zwischen einem oberen Befestigungspunkt und einem unteren Befestigungspunkt am Grundgerüst des Sitzes angebracht. Der obere Befestigungspunkt liegt etwa im Nackenbereich, der untere Befestigungspunkt unmittelbar vor der Abtauchstütze 2 am in Fahrtrichtung gelegenen Ende des Sitzes. Die hängemattenähnliche Bespannung 5 ist zusätzlich mit Spanngurten 6 mit dem Grundgerüst verbunden. Auf der hängemattenähnlichen Bespannung 5 ist eine Polsterung 7 angebracht. Durch die formschlüssige Verbindung 8, die sich etwa auf einem Kreisbogensegment um die virtuelle Drehachse 20 etwa im Hüftbereich des Passagiers liegen soll, ineinander verschieben lässt. Die Sitzneigung kann insbesondere auch dadurch erfolgen, dass die hängemattenähnliche Bespannung um wenigstens einem Befestigungspunkt in einer Schleife herumgeführt ist, so dass durch entsprechende Spannung die Kippbewegung der Rückenlehne bewirkt und gleichzeitig die hängemattenähnliche Bespannung selbst gespannt bleibt.Preferred is according to 3 in the seat a hammock-like covering 5 mounted between an upper attachment point and a lower attachment point on the backbone of the seat. The upper attachment point is approximately in the neck area, the lower attachment point immediately in front of the Abtauchstütze 2 at the end of the seat in the direction of travel. The hammock-like covering 5 is additionally with tension straps 6 connected to the skeleton. On the hammock-like covering 5 is a padding 7 appropriate. Due to the positive connection 8th , which are approximately on a circular arc segment around the virtual axis of rotation 20 should lie about in the hip area of the passenger, can move into each other. The seat inclination can in particular also take place in that the hammock-like covering is guided around at least one attachment point in a loop, so that causes by tilting the tilting movement of the backrest and at the same time the hammock-like fabric itself remains taut.

In einer bevorzugten Ausführung kann, wie in 4 dargestellt, die formschlüssige Verbindung im Übergangsbereich zwischen Sitzkissen und Rückenlehne angeordnet sein. Als Führungselement kommen dann ineinandergreifende Kreissegment 3, 4, die mit Grundgerüstabschnitten 1 im Rücken bzw. 2 im Sitzteil verbunden sind, in Frage. Auch hier sorgt die hängemattenähnliche Bespannung in Verbindung mit dem Polster 7 für die Sitzfunktion, wobei die Bespannung bei Verstellung der Grundgerüstabschnitte entsprechend deren Abstandsänderung nachgeführt wird.In a preferred embodiment, as in 4 represented, the positive connection in the transition region between the seat cushion and the backrest to be arranged. As a guiding element then come interlocking circle segment 3 . 4 that with basic scaffolding sections 1 in the back or 2 are connected in the seat part, in question. Here, too, the hammock-like covering in conjunction with the upholstery 7 for the seat function, wherein the covering is tracked upon adjustment of the basic framework sections according to their change in distance.

In einer speziellen Ausführung kann, wie in 5 dargestellt, die Verbindung zwischen Rückengrundgerüst 1 und Sitzgrundgerüst 2 durch im Querschnitt etwa T- und C-förmige Schienen 4 mit entsprechender Aufnahme 3 vorgesehen sein. Anstelle dieser T- und C-förmigen Profile können andere formschlüssige Verbindungen in Verbindung mit Leichtlaufgleitführungen oder Kugelführungen verwendet werden. An Stelle von Kreissegmenten können selbstverständlich auch zum Beispiel mehrteilig, eine Kreisbewegung durch eine Polygonannäherung bewirkende relativ zueinander verschiebliche Elemente, zum Beispiel zwei etwa tangential an einen Kreis gelegte Geradenstücke, verwendet werden.In a special execution, as in 5 shown, the connection between the backbone framework 1 and seat frame 2 by cross-sectionally approximately T- and C-shaped rails 4 with appropriate recording 3 be provided. Instead of these T- and C-shaped profiles other positive connections can be used in conjunction with Leichtlaufgleitführungen or ball guides. Of course, instead of circular segments, it is also possible, for example, to use multi-part circular elements that move relative to one another by means of a polygonal approach, for example, two straight segments that are approximately tangentially connected to a circle.
