Abstract

In the event of a crash, a component (11) in the seat is used to raise at least the front part of the seat cushion (9).

Description

Die Erfindung betrifft einen Fahrzeugsitz, insbesondere einen Kraftfahrzeugsitz, mit einem Sitzgestell, welches ein Sitzkissen trägt.The The invention relates to a vehicle seat, in particular a motor vehicle seat, with a seat frame, which carries a seat cushion.

Bei einem neigungseinstellbaren Fahrzeugsitz dieser Art ist die Neigung der Sitzfläche durch Anheben oder Absenken des vorderen oder hinteren Randes des Sitzkissens einstellbar. Der Insasse des Fahrzeuges, der den Fahrzeugsitz benutzt, ist in der Regel mittels eines (Dreipunkt-)Gurtes am Fahrzeugsitz festgeschnallt. Wenn das Sitzkissen zu flach eingestellt wird, kann im Crashfall unter Umständen die Gefahr eines Submarinings für den Insassen bestehen, d.h. der Insasse kann unter dem Beckengurtabschnitt des Gurtes hindurchtauchen.at a tilt-adjustable vehicle seat of this kind is the inclination the seat by raising or lowering the front or rear edge of the Seat cushion adjustable. The occupant of the vehicle, the vehicle seat used is usually by means of a (three-point) belt on the vehicle seat strapped. If the seat cushion is set too flat, can in case of a crash under certain circumstances the danger of submarining for the occupants, i. the occupant can under the lap belt section of the belt.

Um dies zu verhindern, wird in Fahrtrichtung vor dem Sitzhöcker des Insassens eine sogenannte Anti-Submarining-Rampe eingesetzt, die ein Durchtauchen des Insassen und damit eine Verletzung desselben verhindert. Die Anti-Submarining-Rampe kann beispielsweise erst im Crashfall erzeugt oder vergrößert werden, oder sie bewegt sich im Crashfall zum Insassen hin. Dabei kann das gesamte Sitzkissen, dessen vorderer Bereich am vorderen Rand alleine oder ein Zwischenbereich zwischen dem vorderen Rand des Sitzkissens und den Sitzhöckern gleichmäßig oder punktuell angehoben werden. Die DE 296 10 078 U1 zeigt ein Anheben des Sitzkissens im Crashfall mittels eines Hebels, welcher von der im Gurt wirkenden Zugkraft mittels eines Zugseils aufgestellt wird.To prevent this, a so-called anti-submarining ramp is used in the direction of travel in front of the seat hump of the occupant, which prevents a penetration of the occupant and thus an injury thereof. The anti-submarining ramp, for example, can only be generated or increased in the event of a crash, or it moves in the event of a crash to the occupant. In this case, the entire seat cushion, the front area of the front edge alone or an intermediate area between the front edge of the seat cushion and the Sitzhöckern be raised evenly or punctiform. The DE 296 10 078 U1 shows a lifting of the seat cushion in the event of a crash by means of a lever which is set up by the tensile force acting in the belt by means of a pull rope.

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.Of the Invention is based on the object, a vehicle seat of the beginning to improve the type mentioned. This object is achieved by a vehicle seat with the features of claim 1 solved. advantageous Embodiments are the subject of the dependent claims.

Das Kniehebelgelenk bietet zunächst einen günstigen Kraftverlauf und am einem definierten Lastniveau durch plastische Verformung die zusätzliche Möglichkeit des definierten Energieabbaus zur Reduzierung hoher Beckenbeschleunigungen.The Toggle joint offers initially a cheap one Force curve and at a defined load level by plastic Deformation the additional possibility the defined energy reduction to reduce high pelvic accelerations.

Im folgenden ist die Erfindung anhand von eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Es zeigt die einzige Figurin the The following is the invention with reference to an illustrated in the drawing embodiment explained in more detail. It shows the only figure

eine schematische Seitenansicht des Ausführungsbeispiels.a schematic side view of the embodiment.

Ein Fahrzeugsitz 101 ist als Vordersitz für ein Kraftfahrzeug ausgebildet. Der Fahrzeugsitz 101 ist mit einem Sitzgestell 103 versehen, das mit der Fahrzeugstruktur des Kraftfahrzeuges in Verbindung steht. Das Sitzgestell 103 weist einen Sitzkissenträger 105 auf, welcher sich in der durch die Fahrtrichtung des Kraftfahrzeuges definierten Längsrichtung des Fahrzeugsitzes 101 zwischen einem vorderen Rand und einem hinteren Rand und in der Richtung quer dazu zwischen den beiden Seiten des Fahrzeugsitzes 101 erstreckt. Auf dem Sitzkissenträger 105 ist ein Sitzkissen 109 angebracht. Der vordere Rand des Sitzkissens 109 ist gegenüber dem vorderen Rand des Sitzkissenträgers 105 in geringem Maße nach oben beweglich, beispielsweise indem eine am hinteren Ende des Sitzkissenträgers 105 angelenkte Sitzschale 110 das Sitzkissen 109 trägt. Zwischen dem Sitzkissenträger 105 und dem Sitzkissen 109 ist im vorderen Bereich des Sitzkissens 109 ein zweiteiliges Kniehebelgelenk 112 angelenkt, dessen Teile normalerweise zusammengeklappt und nach vorne ausgerichtet sind. Im Normalzustand wird der Fahrzeugsitz 101 von einem Insassen des Kraftfahrzeuges benutzt, beispielsweise vom Fahrer, der mittels eines Gurtes 113 am Fahrzeugsitz 101 oder an der Fahrzeugstruktur angeschnallt ist. Der Gurt 113 ist in ein Gurtschloß 114 eingesteckt, welches an einem Arm eines ungefähr mittig an der Sitzstruktur des Fahrzeugsitzes 101 gelagerten Hebel 116 angelenkt ist. Eine Zugkoppel 118, beispielsweise eine Stange oder ein Seilzug, ist an ihrem hinteren Ende an dem anderen Arm des Hebels 116 und an ihrem vorderen Ende in der Mitte des Kniehebelgelenks 112 angelenkt bzw. befestigt.A vehicle seat 101 is designed as a front seat for a motor vehicle. The vehicle seat 101 is with a seat frame 103 provided, which is in communication with the vehicle structure of the motor vehicle. The seat frame 103 has a seat cushion carrier 105 on, which is in the direction defined by the direction of travel of the motor vehicle longitudinal direction of the vehicle seat 101 between a front edge and a rear edge and in the direction transverse thereto between the two sides of the vehicle seat 101 extends. On the seat cushion carrier 105 is a seat cushion 109 appropriate. The front edge of the seat cushion 109 is opposite the front edge of the seat cushion carrier 105 slightly movable upwards, for example by one at the rear end of the seat cushion carrier 105 hinged seat shell 110 the seat cushion 109 wearing. Between the seat cushion carrier 105 and the seat cushion 109 is in the front area of the seat cushion 109 a two-piece toggle joint 112 hinged, whose parts are normally folded and aligned forward. In normal condition, the vehicle seat 101 used by an occupant of the motor vehicle, for example by the driver, by means of a belt 113 at the vehicle seat 101 or strapped to the vehicle structure. The belt 113 is in a belt buckle 114 inserted, which on an arm of approximately centrally on the seat structure of the vehicle seat 101 stored lever 116 is articulated. A train coupling 118 For example, a rod or a cable is at its rear end to the other arm of the lever 116 and at its front end in the middle of the toggle joint 112 hinged or attached.

Im Crashfall, beispielsweise bei einem Frontalcrash, wird der Insasse verzögert abgebremst, d.h. gegenüber dem Fahrzeugsitz 101 nach vorne beschleunigt. Der Gurt 113 blockiert und hält den Insassen in Anlage an den Fahrzeugsitz 101 oder fängt den Insassen nach einem kurzen Weg auf. Durch den nach vorne wirkenden Zug im Gurt 113 erfährt das Gurtschloß 114 eine Zugkraft, die den Hebel 116 schwenkt. Dadurch wird die Zugkoppel 118 nach hinten gezogen, so dass das Kniehebelgelenk 112 gestreckt wird. Die Sitzschale 110 und mit ihr das Sitzkissen 109 werden am vorderen Rand angehoben. Die Anti-Submarining-Wirkung ist dann die gleiche wie im ersten Ausführungsbeispiel. Ein Energieabbau erfolgt durch eine Deformation der Bestandteile des Kniehebelgelenks 110, welche ab einem definierten Lastniveau in geometrisch vorgegebener Weise plastisch verformt werden.In the event of a crash, for example in a frontal crash, the occupant is decelerated delayed, ie with respect to the vehicle seat 101 accelerated forward. The belt 113 blocks and holds the occupant in contact with the vehicle seat 101 or catch the occupant after a short walk. Through the forward pull in the belt 113 experiences the buckle 114 a pulling force affecting the lever 116 swings. This turns the train coupling 118 pulled back so that the toggle joint 112 is stretched. The seat shell 110 and with her the seat cushion 109 are raised at the front edge. The anti-submarining effect is then the same as in the first embodiment. An energy reduction takes place by a deformation of the components of the toggle joint 110 , which are plastically deformed from a defined load level in a geometrically predetermined manner.
