Abstract

The vehicle seat (1) has a backrest with side walls (11), and a changing device for changing curvature of rest sections (9), which are arranged between the side walls. One of the side walls is adjustable in the direction of the curvature of rest sections, and is coupled with curvature adjustments. The side wall adjustment takes place by the changing device for changing the curvature of rest sections. The changing device for changing the curvature and/or the side walls is designed on pneumatic basis.

Description

Die Erfindung bezieht sich auf einen Fahrzeugsitz mit einer Seitenwangen aufweisenden Rückenlehne und einer Vorrichtung zur Veränderung der Wölbung des zwischen den Seitenwangen angeordneten Lehnenabschnitts.The The invention relates to a vehicle seat with a side cheeks having backrest and a device for changing the bulge of the arranged between the side cheeks backrest section.

Fahrzeugsitze mit einer Vorrichtung zur Veränderung der Wölbung des zwischen den Seitenwangen angeordneten Lehnenabschnitts sind in den vielfältigsten Variationen bekannt. Sie werden gewöhnlich als einstellbare Lordosenstützen bezeichnet. Darüber hinaus gibt es bei Fahrzeugsitzen auch Seitenwangen, die sich von Hand oder motorisch bewegen lassen. So ist es bspw. bekannt, die der Fahrzeugtüre zugewandte Seitenwange zurückzufahren, um den Ein- und Ausstieg zu erleichtern.car seats with a device for change the vault of the arranged between the side cheeks backrest section are in the most diverse Variations known. They are commonly referred to as adjustable lumbar supports. About that In addition, there are also side cheeks, which differ from Let hand or motor move. So it is known, for example, the the vehicle door to turn back facing side cheek to to facilitate entry and exit.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Fahrzeugsitz in Hinblick auf eine verbesserte Anpassung an den Sitzbenutzer weiterzubilden.Of the present invention is based on the object, a generic vehicle seat with regard to improved adaptation to the seat occupant.

Die Aufgabe wird dadurch gelöst, dass zumindest eine Seitenwange in Richtung der Lehnenwölbung einstellbar und mit der Wölbungseinstellung gekoppelt ist. Durch die vorgeschlagene Lösung wird also die Seitenwange/n in die Konturierung des Fahrzeugsitzes mit einbezogen. Diese Integration hat den Vorteil, dass unabhängig von der gewählten Wölbungseinstellung des zwischen den Seitenwangen angeordneten Lehnenabschnitts, oftmals auch als Sitzspiegel bezeichnet, die Seitenwangen stets etwa um den gleichen Betrag vorstehen. Das Sitzgefühl und die Sitzseitenführung verändern sich also nicht wie bei den bekannten Lösungen in Abhängigkeit von der Wölbungseinstellung des Sitzspiegels (Lordoseneinstellung).The Task is solved by that at least one side cheek adjustable in the direction of the backrest curvature and coupled with the buckle adjustment is. Through the proposed solution So is the side cheek / n in the contour of the vehicle seat included. This integration has the advantage of being independent of the chosen one curl adjustment of the arranged between the side cheeks backrest portion, often also called seat mirror, the sidewalls always about project the same amount. The seat feeling and the seat side guidance change So not as in the known solutions in dependence from the vault adjustment of the seat mirror (lumbar adjustment).

Gemäß der Erfindung sind die Lehnenwölbung und die Seitenwangeneinstellung miteinander gekoppelt. Eine Kosteneinsparung kann dadurch erreicht werden, wenn gemäß einem weiteren Merkmal der Erfindung die Seitenwangeneinstellung über die Vorrichtung zur Veränderung der Lehnenwölbung erfolgt. Dadurch ist nur eine Antriebseinheit und eine Steuereinheit notwendig.According to the invention are the backrest buckle and the side cheek adjustment coupled together. A cost saving can be achieved if, according to a further feature of Invention the side cheek adjustment on the device for change the Lehnenvölbung he follows. As a result, only one drive unit and one control unit necessary.

Vorteilhaft ist, wenn die Vorrichtung zur Veränderung der Lehnenwölbung in an sich bekannter Weise auf pneumatischer Basis funktioniert und diese Art der Einstellung auch zur Verstellung der Seitenwange Verwendung findet. Entsprechende aufblasbare Einrichtungen lassen sich ohne großen Aufwand nicht nur für die Lordoseneinstellung, sondern auch für die Einstellung der Seitenwange unterbringen. Die Befüllung bzw. Entleerung kann durch flexible Leitungen erfolgen, so dass diese Lösung auch bei schwierigen Bauverhältnissen umsetzbar ist.Advantageous is when the device for changing the backrest buckle in in a known manner works on a pneumatic basis and This type of adjustment is also used to adjust the sidewall place. Appropriate inflatable facilities can be without huge Effort not only for the lumbar adjustment, but also for the adjustment of the sidewall accommodate. The filling or emptying can be done by flexible lines, so that this solution even in difficult construction conditions is feasible.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend näher beschrieben.One embodiment The invention is illustrated in the drawing and will be described below described in more detail.

Die Darstellung zeigt in Seitenansicht einen Fahrzeugsitz 1, der sich aus einem Sitzpolster 3 und einem Rückenteil 5 zusammensetzt. Das Rückenteil 5 besteht aus einem Rahmen 7, an dem ein mittlerer, gepolsterter Lehnenabschnitt 9 sowie zwei Seitenwangen 11 festgelegt sind.The illustration shows a side view of a vehicle seat 1 that is made up of a seat pad 3 and a back part 5 composed. The back part 5 consists of a frame 7 , on which a middle, padded backrest section 9 as well as two side cheeks 11 are fixed.

Der mittlere Lehnenabschnitt 9 lässt sich durch eine in der Zeichnung nicht wiedergegebene pneumatische Vorrichtung zwischen der gestrichelt wiedergegeben Kontur 13 und der strichpunktiert dargestellten Kontur 15 einstellen. In gleicher Weise ist für die beiden Seitenwangen 11 eine Einstellmöglichkeit gegeben, deren Extremwerte durch eine durchgezogene Linie 17 und eine strichpunktiert wiedergegebene Linie 19 dargestellt sind.The middle backrest section 9 can be represented by a non-reproduced in the drawing pneumatic device between the dashed lines contour 13 and the dash-dotted outline 15 to adjust. In the same way is for the two side cheeks 11 given an adjustment, the extreme values by a solid line 17 and a dot-dashed line 19 are shown.

Zur Verdeutlichung der Einstellbereiche ist in der Zeichnung zusätzlich ein Pfeil 21 für den Verstellbereich des Lehnenabschnitts 9 und ein Pfeil 23 zur Kennzeichnung des Verstellbereiches der Seitenwangen 11 eingetragen.To clarify the adjustment ranges, an arrow is additionally in the drawing 21 for the adjustment of the backrest section 9 and an arrow 23 for marking the adjustment range of the side cheeks 11 entered.

Prägendes Merkmal des Fahrzeugsitzes 1 ist der Umstand, dass die Verstellung der Seitenwangen 11 mit der Verstellung des Lehnenabschnittes 9 gekoppelt ist. Das heißt, dass dann, wenn der Sitzbenutzer den Lehnenabschnitt 9 zur Anpassung der Lordosenunterstützung verstellt, in gleicher Weise die Seitenwangen 11 verstellt werden, so dass die Seitenwangen 11 unabhängig von der gewählten Einstellung des Lehnenabschnitts 9 stets um etwa den gleichen Betrag gegenüber dem Lehnenabschnitt 9 vorstehen.Characteristic feature of the vehicle seat 1 is the circumstance that the adjustment of the sidewalls 11 with the adjustment of the backrest section 9 is coupled. That is, if the seat occupant uses the backrest section 9 adjusted to adjust the lumbar support, in the same way the side cheeks 11 be adjusted so that the side cheeks 11 regardless of the selected setting of the backrest section 9 always about the same amount compared to the backrest section 9 protrude.
