Problems solved by technology

Furthermore, when the adjusting element is heavily loaded, the incompletely filled bladder 2 deforms elastically and relaxes again when the loading is insufficient, so that the adjusted position of the adjusting element changes (temporarily) at the same time (whiplash effect), resulting in From a technical safety point of view this can adversely affect the function of the seat sections involved

Embodiment Construction

[0014] exist Figure 2A and image 3 The adjusting device 1 shown in the example shown in FIG. 2 has an adjusting part 3 and a corresponding section 5 which can be part of the motor vehicle seat according to the invention. Preferably, the adjusting part 3 is fixed on the corresponding section 5 via a rotational axis or pivot axis 9 . In the example shown, a preset position can be operatively realized between the adjusting element 3 and the corresponding section 5 , in particular on the section of the adjusting element 3 or of the corresponding section 5 which is opposite the axis of rotation or pivot axis 9 . Tensioning force, the pretensioning force is shown, for example, by the pretensioning device 4, especially the spring. Between the adjusting part 3 and the corresponding section 5 there is a fluid-fillable bladder 2 , whose abutment section 2 b according to the invention has as large an abutment surface as possible, ie without forming a dome. (see the Figure 1A ) rest...

Abstract

A vehicle seat has an adjustment device for adjusting a component of the vehicle seat. The adjustment device comprises at least one bladder that can be filled with fluid and one adjustment component. The bladder is arranged between the adjustment component and a counter section that is provided at the vehicle seat for support such that in the filled state it rests against the adjustment component and the counter section. The bladder is designed for the purpose of adjusting the adjustment component of the vehicle seat between two stop positions; a first stop position in which the bladder is filled minimally and a second stop position in which the bladder is filled maximally. Additionally provided is a pretensioning device, which acts upon the bladder such that during filling the bladder is filled against the pressure acting upon the bladder due to the pretension of the pretensioning device. The pretensioning device exerts a pretension on the bladder already at or in the area of the first stop position. The pretension is designed with such a magnitude that the pretension that acts against the bladder during filling due to the pressure of the adjustment component is greater than that required for retracting the adjustment component or such that the bladder rests against adjustment component and the counter section at or in the area of the first stop position without forming a curvature peak.

Description

technical field [0001] The invention relates to a motor vehicle seat according to the preamble of claim 1 . Background technique [0002] A corresponding motor vehicle seat is already known from DE 10 2004 060 816 A1, in which the adjusting device is adjusted by means of a fluid-fillable bladder in such a way that the adjusting part can be adjusted by means of a filled The lift produced by the bladder moves relative to the seat. The adjusting part of the head restraint is moved by means of this bag in such a way that the adjusting part 1 (see Figure 1A ) is pivoted between a first end position (minimum lift) and a second end position (maximum lift) of the bladder 2 by bladder lift of the bladder 2 , which is supported behind on the bearing part 5 . In order to keep this movement reversible, a return spring is usually provided, which is tensioned during the lifting stroke so that the adjusting part returns to the starting position when the bladder 2 is completely emptied. ...
