Vehicle seat with lordosis support
First Claim
1. Vehicle seat comprising:
- a back rest having a frame with two side parts;
a lordosis supporthaving a pressure plate that is substantially bend-resistant in at least the horizontal transverse direction of the seat, forms a supporting surface in the lordosis region of the back rest and is arranged between the two side parts of the frame;
two holding elements spaced apart from each other in the vertical direction, each holding element extending between the side parts with a length-variable adjustment section that runs in the horizontal transverse direction and connects to the pressure plate, and the holding elements being affixed to the side parts at fixing points arranged opposite each other,the pressure plate being positioned by the holding elements in an inoperative position with a clearance in the horizontal longitudinal direction behind the fixing points; and
a driving device with which the length of the adjustment section can be shortened to thereby reduce the clearance in the horizontal longitudinal direction.

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.
