Rückenkissen mit einer formstabilen Stützplatte

摘要

A back cushion with a form-stable support plate having a plurality of elastically deformable support tongues distributed over its surface. A manually adjustable support strip is located between the support tongues and the support plate. The support strip includes a polyhedral support body the circumference of which is formed by at least three outer surface pairs, each of which has two supporting surfaces located on opposite sides of the support body and are at least essentially parallel to one another. One supporting surface is supported at the support plate while the opposite supporting surface is supported at the support tongues respectively. The opposite supporting surfaces are each located at different distances from one another, and the support body is mounted to rotate around a lengthwise axis in such a manner that, depending on the effective position of the supporting surfaces, different distances of the support tongues with respect to the support plate are obtained.
