Title
(DE) SITZUNTERGESTELL FÜR KRAFTFAHRZEUGSITZE
(EN) SEAT UNDERFRAME FOR MOTOR VEHICLE SEATS
(FR) BÂTI DE SIÈGE POUR SIÈGES DE VÉHICULE À MOTEUR
Abstract
(DE)
Die Erfindung betrifft ein Sitzuntergestell für Kraftfahrzeugsitze, mit zwei im Abstand voneinander angeordneten und jeweils eine Sitzschiene (2) und eine Bodenschiene (3) aufweisenden Schienenpaaren, einem Sitzträger (7), jeweils zwei einenends gelenkig mit dem Sitzträger (7) und anderenends gelenkig mit den Sitzschienen (2) verbundene, den Maximalabstand zwischen dem Sitzträger (7) und den Sitzschienen (2) festlegende Schwenkarme (4, 5) und einer den Sitzträger (7) zwischen einer unteren Ausgangslage und einer Endlage verstellenden Antriebeinheit (6). Um ein Sitzuntergestell für Kraftfahrzeugsitze, insbesondere für Beifahrersitze bereitzustellen, die es ermöglichen, den Kraftfahrzeugsitz in eine Position zu überführen, in der der sich durch die Beinfreiheit ergebende Sitzkomfort hinter dem Kraftfahrzeugsitz in ergänzender Weise gesteigert werden kann, ist vorgesehen, dass die Antriebseinheit (6) zur Verstellung des Sitzträgers (7) über eine im Normalbetrieb festgelegte Höhenendlage hinaus ausgebildet ist.
(EN)
The invention relates to a seat underframe for motor vehicle seats, with two pairs of rails arranged at a distance from each other and each having a seat rail (2) and a floor rail (3), a seat carrier (7), in each case two pivoting arms (4, 5) which are connected at one end in an articulated manner to the seat carrier (7) and at the other end in an articulated manner to the seat rails (2) and fix the maximum distance between the seat carrier (7) and the seat rails (2), and a drive unit (6) adjusting the seat carrier (7) between a lower starting position and an end position. In order to provide a seat underframe for motor vehicle seats, in particular for passenger seats, which enables the motor vehicle seat to be transferred into a position in which the seating comfort, which arises owing to the leg room, can be increased in a complementary manner behind the motor vehicle seat, the drive unit (6) for adjusting the seat carrier (7) is formed beyond a height end position which is fixed during normal operation.
(FR)
L'invention concerne un bâti de siège pour sièges de véhicule à moteur, comprenant : deux paires de rails montées à distance l'une de l'autre, et présentant chacune un rail de siège (2) et un rail de plancher (3), un support de siège (7), deux bras pivotants (4, 5), déterminant la distance maximale entre le support de siège (7) et les rails de siège (2), liés respectivement, de manière articulée, à une extrémité, avec le support de siège (7)et, à l'autre extrémité, avec les rails de siège (2), et un ensemble d'entraînement (6) déplaçant les supports de siège (7) entre une position initiale inférieure et une position terminale. L'invention a pour but d'obtenir un bâti de siège pour sièges de véhicule à moteur, en particulier pour sièges pour passagers, permettant de transférer le siège dudit véhicule, en une position pour laquelle le confort de siège résultant de l'espace pour les jambes, à l'arrière du siège du véhicule, peut être augmenté complémentairement. A cet effet, l'invention est caractérisée en ce que l'ensemble d'entraînement (6) pour le déplacement du support de siège (7) est configuré via une position terminale en hauteur, pré-établie en fonctionnement normal.
