摘要

One side of the flexible support layer has flexible pyramids (15,25) with a square base surface, and equilateral triangles (6) as side surfaces or flexible truncated parts of the pyramids. The pyramids and triangles are arranged in a square grid shape. The lines (8) that divide the pyramids or truncated pyramids, enable the support layer to be cut or folded along them and the adjacent parts of the support layer to be formed into a right angle, so that the pyramid side surfaces or truncated pyramid side surfaces lie flat against each other.
