example 1

[0064] An adjusting device for longitudinally adjusting a vehicle seat (F), having

[0065] - at least one rail (3) for presetting the seat longitudinal axis (L) and for supporting at least one adjustment unit (2.1, 2.2) of said adjustment device (1A, 1B), along said seat longitudinal axis, the seat frame (G) of the vehicle seat (F) is adjustable, and

[0066] - at least two adjustment units (2.1, 2.2) movably guided and arranged successively along the longitudinal axis (L) of the seat, on which adjustment units the seat chassis (G) can be fixed, so as to be adjustable along said seat longitudinal axis (L),

[0067] It is characterized in that,

[0068]The at least two adjustment units (2.1, 2.2) are adjustable relative to each other along the seat longitudinal axis (L), and each adjustment unit (2.1, 2.2) is assigned its own drive (4.1, 4.2 ) for externally operated adjustment along the longitudinal axis (L) of the seat.

example 2

[0070] Adjustment device according to example 1, characterized in that at least one adjustment unit (2.1, 2.2) has a bearing part (20) for connection with a wing of the seat chassis (G).

example 3

[0072] The adjusting device according to example 1 or 2 is characterized in that, in order to adjust at least one adjusting unit (2.1, 2.2) by external force, a screw (7) and a screw nut (801) engaging with it are provided.

Abstract

The invention relates to a vehicle seat which comprises an adjustment device for the longitudinal adjustment of a vehicle seat (F). The adjustment device (A, B) comprises: -at least one rail (3) for predetermining a seat longitudinal axis (L) and supporting at least one adjustment unit (2.1, 2.2) of the adjustment device (1A, 1B), wherein a seat chassis (G) of the vehicle seat (F) is adjustable along the seat longitudinal axis; and -at least one adjustment unit (2.1, 2.2) which is movably guidable and adjustable by use of a screw (7) and a screw nut engaged with the screw, wherein the seat chassis (G) is fixable to the adjustment unit so as to be adjustable along the seat longitudinal axis (L). The at least one adjustment unit (2.1, 2.2) is movably supported on the at least one rail (3) through the at least one support element (22, 23, 24, 25).

Description

[0001] This application is a branch of an application whose international filing date is December 11, 2017, national application number is 201780074626.9 (international application number is PCT / EP2017 / 082119), and the title of the invention is "Adjustment device for longitudinally adjusting vehicle seat". case application. technical field [0002] The invention relates to an adjustment device for longitudinal adjustment of a vehicle seat. Background technique [0003] Adjustment devices commonly used in practice have, inter alia, a first rail provided for fastening to the vehicle floor and a second rail provided for connection to the seat frame of the vehicle seat. In this case, the second rail is mounted in an adjustable manner relative to the first rail in order to enable a longitudinal adjustment of the vehicle seat in the seat longitudinal direction. Typically, the vehicle seat has two pairs of first and second rails via which the vehicle seat is longitudinally movably...
