Abstract
Abstract A bullet-proof garment including several layers of textile fabric or foil superimposed on a shock absorber, in which the shock absorber is a three-dimensional fabric with waffle-like surfaces, a hollow part of at least 90% by volume and a thickness of 5 to 30 mm. Such fabrics are distinguished by good pressure resistance and make possible a good conversion of energy.
