Abstract

The vehicle seat (1) is fitted with a rail (3) under each side edge to interlock with a front rail (4) on a tilting floor support (7) and with a rear rail (5) on a height adjustable tilt support. The seat height can be adjusted by the rear mounting and the seat longitudinal setting is adjustable by the rails. The settings can be locked in any position. The front tilt mounting is braced on a transverse support bar (7) which provides lateral strength an a side impact. The rear mounting is via tilt levers (8) to raise and lower the rear of the seat. The height adjustment also involves some longitudinal adjustment.

Description

Die Erfindung betrifft eine Sitzanordnung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a seating arrangement according to the preamble of claim 1.

Derartige Sitzanordnungen sind in einer Vielzahl von Ausführungs­ formen bekannt, vergleiche zum Beispiel DE 40 36 608 A1 und DE 41 19 418 C1. Sie sind alle mehr oder weniger aufwendig und meistens nicht oder nur unter erheblichem Aufwand geeignet, Einsatz zu finden, wenn es darum geht, eine Sitzanordnung oder Teile davon in einen Seitenaufprallschutz mit einzubeziehen.Such seat arrangements are in a variety of designs known forms, compare for example DE 40 36 608 A1 and DE 41 19 418 C1. They are all more or less complex and mostly not suitable or only suitable with considerable effort, use find when it comes to a seating arrangement or parts of it to be included in a side impact protection.

So liegt denn der Erfindung die Aufgabe zugrunde, eine gattungs­ gemäße Sitzanordnung zu finden, die einfach im Aufbau ist und auch dann mit Vorteil eingesetzt werden kann, wenn ein seitlicher Aufprallschutz in Form eines sich über die Fahrzeugbreite erstrec­ kenden Querträgers gefordert wird.So the invention is based on the task, a genus find appropriate seating arrangement that is simple in construction and can also be used with advantage if a side Impact protection in the form of an extension over the width of the vehicle kenden cross member is required.

Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Patent­ anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved with the characteristic features of the patent claim 1 solved. Advantageous refinements are the subject of subclaims.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert. Darin zeigenAn embodiment of the invention is described below with reference to Drawing explained in more detail. Show in it

Fig. 1 den prinzipiellen Aufbau einer erfindungsgemäßen Sitz­ anordnung in Seitenansicht und Fig. 1 shows the basic structure of a seat arrangement according to the invention in side view and

Fig. 2 einen Überblick über die Verstellbereiche am Beispiel von vier ausgewählten Sitzpositionen. FIG. 2 is an overview of the adjustment ranges using the example of four selected seat positions.

Der dargestellte Sitz umfaßt das eigentliche Sitzteil 1 und eine Rückenlehne 2, die beide relativ zueinander verstellbar sein kön­ nen. Die unterhalb des Sitzteils 1 angeordneten Verstell- und Feststelleinrichtungen dienen zum einen der Verstellung des Sit­ zes in Fahrzeuglängsrichtung, zum anderen einer Höhenverstellung des Sitzes, genauer gesagt einer Neigungsverstellung des Sitzes 1. Die Feststelleinrichtungen sind im einzelnen nicht darge­ stellt, sie sind jedoch in verschiedenen Ausführungsformen be­ kannt. Zur Längsverstellung dient eine Schienenanordnung, beste­ hend aus je einer (d. h. links und rechts angeordneten) sitzteil­ festen Oberschiene 3 und je einer, in einen vorderen Abschnitt 4 und einen hinteren Abschnitt 5 unterteilten Unterschiene. Die vordere Unterschiene 4 ist um eine fahrzeugfeste erste Querachse 6 schwenkbar und stützt sich dabei auf einem fahrzeugfesten Quer­ träger 7 ab, der als Seitenaufprallträger ausgebildet ist und als solcher die Folgen eines Seitencrashs für die Fahrzeuginsassen mildern soll.The seat shown comprises the actual seat part 1 and a backrest 2 , both of which can be adjustable relative to one another. The adjustment and locking devices arranged below the seat part 1 serve on the one hand to adjust the position in the vehicle longitudinal direction, and on the other hand to adjust the height of the seat, more precisely an inclination adjustment of the seat 1 . The locking devices are not shown in detail Darge, but they are known in various embodiments. For longitudinal adjustment is used a rail arrangement, consisting of one (ie left and right) seat part fixed upper rail 3 and one, each divided into a front section 4 and a rear section 5 lower rail. The front lower rail 4 is pivotable about a vehicle-fixed first transverse axis 6 and is supported on a vehicle-fixed cross member 7 , which is designed as a side impact beam and as such is intended to mitigate the consequences of a side crash for the vehicle occupants.

Die hintere Unterschiene 5 ist über eine Schwinge 8 in zwei Ge­ lenken 9, 10 mit dem Fahrzeugboden 11 verbunden.The rear lower rail 5 is connected via a rocker 8 in two Ge 9 , 10 connected to the vehicle floor 11 .

Wie Fig. 2 zeigt, bietet die erfindungsgemäße Sitzanordnung dem Benutzer vielfache individuelle Einstellmöglichkeiten, insbeson­ dere durch die überlagerte Höhen- und Längsverstellung. Beispiel­ haft sind in Fig. 2 vier Sitzpositionen dargestellt, die mit a bis d gekennzeichnet sind. In der Stellung a ist der Sitz, genau­ er gesagt die Sitzhinterkante, am weitesten abgesenkt und in der hintersten Position. Durch leichtes Anheben der Sitzhinterkante, was in der Praxis durch Federkraft erfolgt, nachdem die entspre­ chende Feststelleinrichtung gelöst worden ist, nimmt der Sitz die Stellung b ein; dabei bleibt die Lage der Sitzvorderkante prak­ tisch unverändert. Durch weiteres Anheben der Sitzhinterkante ge­ langt diese bei senkrecht stehender Schwinge 8 in ihre höchstmög­ liche Stellung c mit dann horizontal liegenden Schienen 3, 4, 5. As shown in FIG. 2, the seat arrangement according to the invention offers the user multiple individual setting options, in particular through the superimposed height and length adjustment. As an example, four seating positions are shown in Fig. 2, which are marked with a to d. In position a, the seat, or more precisely, the rear edge of the seat, is most lowered and in the rearmost position. By slightly lifting the rear edge of the seat, which is done in practice by spring force after the corresponding locking device has been released, the seat assumes position b; the position of the front edge of the seat remains practically unchanged. By further lifting the trailing edge of the seat ge reaches this with the rocker arm 8 standing vertically in its highest possible position c with the rails 3 , 4 , 5 lying horizontally.

Wie man erkennt, hat sich dabei die Sitzvorderkante etwas nach vorn verlagert, ohne daß der Sitz in seinen Schienen bewegt wor­ den ist. Erforderlichenfalls kann der Sitz jetzt noch nach Lösen der Schienen-Feststelleinrichtung bis in seine Stellung d nach vorn gefahren werden.As you can see, the front edge of the seat has a bit of a backlash shifted forward without the seat moving in its rails that is. If necessary, the seat can now still be loosened the rail locking device up to its position d be driven in front.

Die im Fahrbetrieb erforderliche Festlegung des Sitzes erfolgt über geeignete Feststelleinrichtungen. Diese müssen so gewählt werden, daß weder eine Verschiebung noch ein Verschwenken des Sitzes möglich ist. Dazu gibt es unterschiedliche Möglichkeiten. So ist es denkbar, in einer gewählten Sitzposition die beiden Un­ terschienen 4, 5 mit der Oberschiene 3 zu verrasten, eine spezi­ elle Verdrehsicherung erübrigt sich dann. Eine andere Möglichkeit ist die, im Bereich des Gelenkes 9 eine kombinierte Feststellein­ richtung vorzusehen, die sowohl Dreh- als auch Verschiebebewegun­ gen an dieser Stelle verhindert; damit sind auch Dreh- und Ver­ schiebebewegungen an anderen Stellen ausgeschlossen.The fixing of the seat, which is necessary when driving, is carried out using suitable locking devices. These must be selected so that neither a shift nor a pivoting of the seat is possible. There are different ways to do this. It is conceivable to lock the two lower rails 4 , 5 with the upper rail 3 in a selected sitting position, a special anti-rotation device is then unnecessary. Another possibility is to provide a combined locking device in the area of the joint 9 , which prevents both rotational and displacement movements at this point; This also prevents turning and sliding movements in other places.
