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.
