FABRIC ARMOUR VEST WITH ANTISHOCK DEVICE Russian patent published in 2014 - IPC F41H1/02 

FIELD: weapons and ammunition.

SUBSTANCE: invention proposes a fabric armour vest containing chest and back sections, in the covers of which there located are protective screens (fabric packs) from high-strength aramid fabric (TSVM or equivalent), and on their inner surfaces there located is an antishock device including a shock absorber and a base material. The shock absorber provides for removal of a fabric pack of the armour vest from the base material to implement deflection of a fabric pack during incorporation of a damage agent into it. The base material is made in the form of shock compensators of sections representing chambers from air-tight rubber-coated aramid fabric with elastic filler inside it, which are lined on both sides with packs of plates; besides, the back pack of plates is bonded to shock compensators so that centres of masses of its square elements can be located opposite angular points of connected shock compensators. Packs of plates represent assemblies of fabric layers of the same base as the primary protection of the armour vest (TSVM or equivalent), which are bonded to each other to ensure stiffness, except for a bending zone. Sizes of plates of the pack in the form of squares are chosen based on equality to maximum specific size of the base of cavern of a temporary cavity formed in soft tissues of a biological object at non-penetration of the fabric armour vest. In each shock compensator there is one or more tightly closed holes with a total surface area referring to front area of the shock compensator of not more than 1:8, which provide for air efflux from the shock compensator at constant pressure, at which holes are opened due to action of the pack plates involved in movement through the primary protection of the armour vest.

EFFECT: reduction of degree of a damaging action of damage agent on a biological object at non-penetration of an armour vest without any increase of its weight.
