ABSTRACT:
A soft protective construction for body protection, such as a bullet-proof vest or shirt is disclosed wherein a double layered bullet-stopping arrangement of mutually moveable rectangular or square protective plates is provided which plates can preferably be inserted into pockets of a carrier material. The outer layer of plates lying on the bullet impact side consists of steel and at least in portions thereof said outer plates are overlapped in scale-like fashion. The inner plate layer, which lies closer to the body than does the outer layer, is designed to absorb or largely destroy the impact energy of a striking bullet. The protective plates of the inner layer next to the body comprise a thick shock absorbing material, in particular a plastics material, such as polyamide, and said inner plates are arranged in a common plane and are joined together in a form-locked manner along the horizontally oriented, meeting plate edges by slide joints (5) and along the vertically oriented and likewise meeting plate edges by rotating joints (6, 11, 16, 17, 22, 23, 24). Preferably, the inner layer plates comprise a casting polyamide obtained by an activated anionic polymerization of monomeric laurolactam which has a Vicat B softening point of not less than about 183.degree. C., preferably about 160.degree. C. to 168.degree. C.
