Claim Text:
1. 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 at least one of piercing, cutting and sawing, sub-dividing by said material attenuations the base material into a plurality of material cells, said material cells delineated from each other by said material attenuations but still connected to each other, wherein the material attenuations are passages extending from an upper side to a lower side of the reinforcing structure and are incorporated in such a way that bridges remain between adjacent material attenuations and connect adjacent material cells to each other, wherein a cross-sectional area of the bridges is reduced by compression and the bridges are compacted from the upper side and the lower side, such that they fall short of the upper side and the lower side of the respectively adjacent material cells.
