Embodiment Construction

[0042] figure 1 , 2 , 3A and 3B exemplarily show an embodiment of the adjusting device 1A according to the invention. The adjustment device is Figure 4 Part of the track set SA of the vehicle seat F. The adjusting device 1A here represents, by way of example, the mirror-image adjusting device 1B of the rail arrangement SA, which corresponds to Figure 4 It is provided on the other (right) seat longitudinal side of the vehicle seat F.

[0043] The vehicle seat F has a seat chassis G and a backrest R pivotally supported thereon. Via the rail arrangement SA, the seat chassis G and thus the vehicle seat F are movable along the seat longitudinal axis L such that the seat longitudinal position of the vehicle seat F is adjustable. In support member 20 (see figure 1 , 2 , 3A and 3B) to connect the seat chassis G to the adjustment devices 1A and 1B of the track device SA. These bearing parts 20 are in each case part of an adjusting unit of the respective (left or right) adjust...

Abstract

The invention relates, in particular, to an adjustment device for the longitudinal adjustment of a vehicle seat (F), having at least one rail (3) for predetermining a longitudinal seat axis (L), alongwhich a base (G) of the vehicle seat (F) can be adjusted, and for bearing at least one adjustment unit (2.1, 2.2) of the adjustment device (1A, 1B), and at least two displaceably guided adjustment units (2.1, 2.2), which are arranged one behind the other along the longitudinal seat axis (L) and on which the seat base (G) can be fitted so as to be adjustable along the longitudinal seat axis (L). According to the invention, the at least two adjustment units (2.1, 2.2) can be adjusted relative to one another along the longitudinal seat axis (L), and each adjustment unit (2.1, 2.2) is assigned adedicated drive (4.1, 4.2) for power-operated adjustment along the longitudinal seat axis (L).

Description

technical field [0001] The invention relates to an adjustment device for longitudinal adjustment of a vehicle seat. Background technique [0002] 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 arranged on the vehicle floor. In order to adjust the second rail relative to the first rail, the adjusting device often has an (adjusting) screw and a screw nut which engages with the screw. [0003] When using a rigid second rail, on which the seat frame is fastened, only longitudinal adjustment of the vehicle seat is poss...
