The cushion according to the invention is made up of several layers of pneumatic elements () which each form a matrix (). These pneumatic elements () each have a multiplicity of holes () into which elastic spring elements, for example foam cylinders (), are inserted. The pneumatic elements () are all substantially congruent, such that the holes () of superposed pneumatic elements () are in each case located at the same places. An individual pneumatic element () is produced from two superposed sheets of an elastic plastic. The two sheets are welded sealingly to each other at the edges of the cushion and at the edges of the holes (). The holes () are cut out after the welding. Each pneumatic element () has at least one connection for compressed gas. While supporting a patient, the pneumatic elements () are alternately supplied with compressed gas and then relaxed again. This has the effect of changing the load of the patient from more on the pneumatic elements to more on the spring elements, and vice versa.

Cushion for supporting patients and for preventing pressure sores

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