Abstract
A cushion portion has a core comprising a foamed reaction mixture optionally covered at its front side with a cover. A covering device which is stable in respect of shape is provided at the rear side of the core. Provided between the rear side of the core and the covering device is an intermediate structure comprising first and second foils which lie loosely against each other to define at least one inflatable space therebetween. A tube opens into the inflatable space for controllable inflation thereof to be able to alter the external contour of the cushion portion.
