Pneumatic Lordosis Support
First Claim
1. A pneumatic lordosis support (1) consisting of at least one pressurized cushion (3) comprising a front side (5) and a rear side (6), characterized in thatthe cushion (3) has at least one uncontinuous first connection (8) of the front side (5) with the rear side (6), said connection (8) being substantially parallel to the spine of a user and subdividing the cushion into compartments,the cushion (3), in the region of a center line (7) of the cushion (3) being substantially parallel to the spine of the user, encompasses further central connections (10) of the front side (5) with the rear side (6) being substantially perpendicular to the spine of the user, said connections being offset in the direction of the spine of the user with reference to the first connections (8) and being shorter than half the width of the cushion (3).

Abstract
A pneumatic lordosis support (1) consists of a cushion (3), which is integrated into the backrest (2) of a seat. Laterally of a vertical center line (7), the cushion encompasses horizontal connections (8) between a front side and a rear side of the cushion (3). The cushion (3) is composed of an air-tight flexible membrane. In the region of the vertical center line (7), the connections (8) encompass breaks. Vertically offset to the connections (8), the cushion (3) encompasses further central horizontal connections (10), which extend substantially across the region of the breaks in the connection (8). In the region where connections (8) and central connections (10) are located close to one another, reduced radii of the membrane lead to the occurrence of less stress than in the remaining cushions (3) and allow the spine of a user to dip into the cushion (3) more softly.
