COLLISION PROTECTING DEVICE Russian patent published in 2005 - IPC

FIELD: personal protection-gear.

SUBSTANCE: collision protecting device comprises metallic plate and protecting plate made of a layered material. The thickness of the protecting plate is 0.2d_b < b₂ < 0.3d_b, and it is mounted on the face side of the metallic plate that undergoes shock. The metallic plate is made of a material whose rigidity is no less than 300 HB and thickness b₂ > 0.8d_b, where d_b is the diameter of the bullet, b₁ is the thickness of the metallic plate, and b₂ is the thickness of the protecting plate. The protecting plate can be made of a material with low specific density and high compression strength, say glass textolite.

EFFECT: enhanced reliability.
