ABSTRACT:
The invention relates to a vehicle seat with a back rest having a frame (2) and a lordosis support (6), with the following additional configuration: The lordosis support (6) comprises a pressure plate (9) that is essentially bend resistant in at least the transverse direction of the seat or the Y-direction, forms a supporting surface in the lordosis region of the back rest and is arranged between two side frame parts (3) of the frame (2); there is at least one holding element (5a,5b) that extends between the side frame parts (3) with a length-variable adjustment section (21), which runs in the Y-direction and connects to the pressure plate (9), and is affixed there at fixing points (30) arranged opposite each other; in an inoperative position, the pressure plate (9) is arranged with a horizontal clearance (11) or a clearance in the X-direction behind the fixing points (30); there is a driving device with which the length of the adjustment section can be shortened as the horizontal clearance is reduced.
