Abstract
A pneumatic couch includes an airtight envelope divided into a lower skin and an upper skin. The airtight envelope includes low-stretch material. The pneumatic couch also includes at least one valve for inflation with compressed air and deflation. Between the lower skin and the upper skin, a plurality of flexible webs are arranged running in vertical planes substantially parallel to each other. The flexible webs comprise low-stretch material and are joined over the entire length of the flexible webs both to the lower skin and to the upper skin. At an upper and a lower end of the couch, the airtight envelope overlaps the flexible webs and the lower skin and the upper skin are joined airtight. The airtight envelope overlaps an outermost web on a first and second long side and the lower skin and the upper skin are joined airtight. On one long side of the couch both the lower skin and the upper skin continue past the airtight joint, and are taken around a rear wall and joined to each other, and form a back part. The back part is substantially of the same length and shape as an adjacent web, and the rear wall is so constructed that the rear wall can be fastened onto a load bearing wall or to a suitable bearing construction. The couch thereby assumes the shape of a cantilever.
