Ballistic collar may include a bellows shaped member, which is arranged to surround a human's neck, including bellows plies being mainly perpendicular to the axis of the collar or of the human's neck. Free standing, the structure stands up around the neck to provide ballistic protection. The structure may be formed by folding a sheet of ballistic rated body armor fabric including strong synthetic fibers, e.g. from aromatic polyamide fibers, or ultra high molecular weight polyolefin, e.g. polyethylene polypropylene, fibers. For manufacturing the ballistic collar, a plurality of sheets may be piled-up and the whole may be submitted to transformation in a mold at a temperature and pressure at which the sheets remain mainly loose from each other. Preferably parts of the collars or bellows shaped members are made, which are assembled afterwards e.g. by stitching, welding etc. |

1. A ballistic collar for protection against bullets and shrapnel, comprising:
a structure of body armor fabric with successive strips that run over into each other by folds of the fabric, each of the folds running substantially perpendicularly to a vertical axial direction of the collar; a matrix of preformed resilient resin, the body armor fabric located in the matrix, the matrix of preformed resilient resin having sufficient stiffness to cause the structure to stand up freely as a resiliently vertically compressible and expandable collar to completely surround a human's neck, whereby the collar will be expanded or compressed resiliently at the front and the back of the neck during head movements, increasing or decreasing fold angles between the strips at the folds; and wherein the body armor fabric ends at an upper edge with one of the successive strips, wherein the upper edge is configured to reach a chin of a human's head when the collar is expanded. |
