Abstract
Lordosenstütze für Rückenlehnen (1) von Kraftfahrzeugsitzen, die zwei zueinander spiegelsymmetrisch angeordnete, elastisch verformbare Abstützbereiche (4;5) aufweist, die mit seitlichem Abstand zur Längsmittelebene des Kraftfahrzeugsitzes angeordnet und in dessen Längsrichtung verstellbar sind., dadurch gekennzeichnet, daß beide Abstützbereiche (4;5) von einem die Seitenholme (1a;1b) der Rückenlehne (1) verbindenden Querträger (3) gehalten werden sowie ein Ende (4b;5b) jedes Abstützbereichs unverschieblich daran befestigt und das jeweils andere Ende (4a;5a) verschieblich auf diesem Querträger (3) geführt ist.Lumbar support for backrests (1) of motor vehicle seats, which has two mutually mirror-symmetrically arranged, elastically deformable support areas (4; 5), which are arranged at a lateral distance from the longitudinal center plane of the motor vehicle seat and are adjustable in the longitudinal direction thereof, characterized in that both support areas (4 ; 5) are held by a cross member (3) connecting the side rails (1a; 1b) of the backrest (1), and one end (4b; 5b) of each support area is immovably fastened to it and the other end (4a; 5a) is displaceable thereon Cross member (3) is guided.
Description
Die Erfindung betrifft eine Lordosenstütze nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a lumbar support the preamble of claim 1.
Eine bekannte Lordosenstütze dieser
Art (
Es ist weiterhin eine Lordosenstütze bekannt (
Auch bei einer weiteren bekannten
Lordosenstütze
(
Die zuletzt genannten Lordosenstützen üben einen Druck auf die Wirbelsäule aus, der durch die mit der Vergrößerung der Stützwirkung häufig einhergehende Erhöhung der Polsterhärte im Lordosenbereich noch verstärkt wird. Eine starke Druckbelastung der Wirbelsäule selbst ist jedoch ergonomisch ungünstig.The last mentioned lumbar supports practice one Pressure on the spine from that with the enlargement of the supporting action frequently accompanying increase the upholstery hardness reinforced in the lordosis area becomes. However, a high pressure load on the spine itself is ergonomic unfavorable.
Es hat sich gezeigt, daß eine Abstützung des im Lordosenbereich beiderseits der Wirbelsäule angrenzenden Rückenbereichs günstiger ist und zu einem ermüdungsärmeren und komfortableren Sitzen führt.It has been shown that a support of the Lumbar area on either side of the spine adjacent back area better is and to a less fatigue and leads to more comfortable sitting.
Ausgehend von dem eingangs erwähnten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Lordosenstütze der als bekannt vorausgesetzten Art so auszubilden, daß sie einfach und platzsparend aufgebaut ist und eine gezielte Längsverlagerung der spiegelsymmetrisch angeordneten Abstützbereiche ohne Lageveränderung oder Veränderung der Polsterhärte im zentralen Bereich zwischen den Abstützelementen erlaubt.Based on the status mentioned at the beginning The underlying technology of the invention is the object of a lumbar support as a known presupposed type so that it is easy and is space-saving and has a targeted longitudinal shift the mirror-symmetrically arranged support areas without changing position or change the upholstery hardness allowed in the central area between the support elements.
Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Patentanspruchs 1.This task is solved with the features of claim 1.
Die erfindungsgemäße Lordosenstütze unterstützt den Rücken im Lordosenbereich, ohne die Wirbelsäule selbst zu belasten.The lumbar support according to the invention supports the move in the lordosis area without stressing the spine itself.
Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Preferred embodiments of the invention result itself from the subclaims.
Die Stützwirkung der Lordosenstütze ist auf einfache Weise und gezielt veränderbar. Es ist auch zweckmäßig, daß die Lordosenstütze zusätzlich in der Höhe verstellt werden kann. Unabhängig von der seitlichen Vorwölbung der Abstütz bereiche kann die Lordosenstütze in einer weiteren bevorzugten Ausführungsform zusätzlich auch insgesamt in Sitzlängsrichtung verlagerbar sein.The supportive effect of the lumbar support is easily and specifically changeable. It is also appropriate that the lumbar support in addition Height adjusted can be. Independently from the lateral bulge the support areas can the lumbar support in a further preferred embodiment additionally overall in the longitudinal direction of the seat be relocatable.
Nachstehend wird eine bevorzugte Ausführungsform der Erfindung anhand der Zeichnungen im einzelnen beschrieben. Es zeigen: Below is a preferred one embodiment the invention with reference to the drawings described in detail. It demonstrate:
