Patent ID: 8668853

Claim:
A method for manufacturing a three-dimensionally deformable, sheet-like reinforcing structure, comprising: incorporating material attenuations into a sheet-like, cellular base material, distributed over an area of the base material, by cutting or sawing, said material attenuations sub-dividing the base material into a plurality of material cells said material cells delineated from each other by said material attenuations but are still connected to each other, wherein the material attenuations are incorporated in such a way that one or more bridges remain between adjacent material attenuations and connect adjacent material cells to each other; wherein a cross-sectional area of said bridges is reduced by compression; wherein said bridges are compacted, such that said bridges fall short of an upper side and a lower side of said adjacent material cells: wherein the material cells are compacted near the surface and thus rounded on an upper side or a lower side, along at least a part of edges formed by incorporating the material attenuations; and wherein the material cells are heated at least in the region of the edges to be rounded, and are compacted near the surface along the heated edges.
