Patent ID: 7428801

Claim:
A ceiling structure comprising: a number of sheets that span between parallel beams mounted underneath a fixed ceiling; wherein the sheets can, by elastic deformation, be taken from an initial configuration to a desired curved configuration in which the sheets are intended to form the visible ceiling face; wherein the sheets have a first expanse along the beams and a transverse second expanse; wherein the sheets along said first expanse have edge portions configured for abutting on abutment areas on the beams; wherein the ceiling structure also comprises force-transmitting means that are configured for cooperating with portions of the sheets, which portions are arranged between said edge portions, in order to provide, in combination with the abutment force of the sheets against the abutment areas, the flexular moment necessary for maintaining the desired curved configuration of the sheets; and wherein the transverse second expanse is larger than the distance between the beams.
