Embodiment Construction

[0042] figure 1 A modular adjustment device V is shown in a perspective view with reference to the spatial orientation of the xyz vehicle seat coordinate system, which can be used, for example, for leg rests, upper backrest parts of split backrests or lumbar supports, which Fits into the seat or backrest of a vehicle seat and connects to the strength structure of the seat or backrest. In this case, the adjustment device V has two support elements in the form of two support rods 20 and 21, which can act on an optionally upholstered seat element S, for example a comfort cushion of a vehicle seat (cf. Figure 7A and Figure 7B ) in order to variably change the contour and / or position of the seat element S, especially its curvature and / or width. In this case, a body part of the seat user is usually supported by the seat element S when the seat user normally occupies the vehicle seat.

[0043] In order to connect the adjusting device V to the strength structure of the vehicle se...

Abstract

The invention relates in particular to an adjusting device for a seat element (S) of a vehicle seat, which seat element supports a body part of a seat user, comprising at least one drive apparatus (4a, 4b), which comprises a spindle drive, and comprising at least one adjustable support element (20, 21) for changing the contour or position of the seat element (S), the spindle drive comprising a spindle (5), which extends along a spindle axis (SA) and which is mounted in a floating manner at a spindle end (50) by means of a spindle holder (7, 7') in such a way that the spindle (5) can be moved at said spindle end (50) in at least one spatial direction (x, y) extending transversely to the spindle axis (SA). According to the invention, the spindle holder (7, 7') comprises a first and a secondcompensation element (70, 71) for movability of the spindle end (50) with respect to two spatial directions, a first and a second spatial direction (x, y), which extend approximately perpendicularly to each other and perpendicularly to the spindle axis (SA), the spindle end (50) being retained at the first compensation element (70) preferably for movement in the first spatial direction (y) and thefirst compensation element (70) being retained together with the spindle end (50) at the second compensation element (71) preferably for movement in the second spatial direction (x).

Description

technical field [0001] The invention relates to an adjustment device for a seat element of a vehicle seat supporting a body part of a seat user. Background technique [0002] In this case, the adjusting device is used, for example, to variably change the shape of the seat bottom, of the support region of the backrest or of the headrest or of the side pads of the vehicle seat by means of at least one support element of the adjusting device. In particular, the adjusting device can be set and provided for adjusting the lateral support area of ​​the seat bottom or of the side bolsters or of the backrest, the shoulders of the vehicle occupant and the support area of ​​the upper rest part of the backrest separated in the head area, the head The curvature and / or the width of the pillow, of the lumbar support in the lumbar region of the vehicle occupant or of the leg support cushion of the seat bottom. In this case, the adjusting device can be constructed modularly and in this way ...
