  • the repairman Prior to returning to Utopia, the repairman moves sling 60 so that it hangs from snaps along the midline of the cabin interior. This positioning 104 is chosen because Hades will be on his right side as he travels south from Chaos to Utopia. Plate 20 on the front windscreen is not moved for the return trip. On his return trip, a sniper crouching in bushes three meters from the highway opens fire on the repair truck with an automatic rifle.
  • Four projectiles 34 hit the repair truck. The first projectile 34 hits the left side of the front windscreen where it is stopped by plate 20 installed there, the second projectile 34 hits the right side of the front windscreen and then plate 40 in sling 60 hanging in the center of the passenger cabin. The third projectile hits the right front window of the truck and is similarly stopped by plate 40 in sling 60 hanging in the center of the passenger cabin.
  • the fourth projectile hits the rear portion of the right side of the truck and passes through the truck behind the driver.
  • the glass layer 22 of plate 20 installed in the front windscreen is preferably replaced as it is cracked from the impact of the first projectile.
  • the front windscreen and front passenger side window of the truck are preferably replaced.
  • the repairman has not been injured by projectiles 34 or glass shrapnel. It will be appreciated that, if the repairman lived in Chaos, he could use the same armoring kit (plates 20 and 40, sling 60 and cases 80, for his own car and for his repair truck provided that reversible attachment devices are available in both vehicles. Alternately, or additionally, if the repairman visited Chaos frequently, he might choose to leave one or more components of the armoring kit installed all the time, instead of assembling and mounting them for specific trips.
  • two people traveling in the same vehicle could combine two kits to armor the full front windscreen and both front doors. Additional armoring kits could add protection to additional portions of a vehicle since the system of the present invention is fully modular.

Abstract

La présente invention concerne des plaques de blindage légères, des systèmes les intégrant, et des procédés d'utilisation correspondant. L'invention concerne plus particulièrement une plaque de blindage transparente incluant au moins une couche de verre, au moins une couche de plastique représentant au moins 50% de la masse totale de la plaque, au moins une colle réunissant les deux couches. L'invention concerne également une plaque de blindage opaque comprenant au moins deux couches de métal durci et une couche de dissipation des forces. Qu'elle soit opaque ou transparente, la plaque présente une masse totale inférieure à environ exactement 50 kg/m2. L'invention concerne en outre un système de protection de cible contre l'impact d'un projectile incluant au moins une plaque de blindage selon l'invention, et un dispositif de positionnement servant à amener et bloquer la plaque de blindage en une position entre la cible et le projectile. L'invention concerne enfin un procédé de protection d'une cible contre l'impact d'un projectile, impliquant de reconnaître au moins une source d'où un projectile est susceptible de provenir, et employant un dispositif de positionnement servant à positionner au moins une plaque de blindage dans une position entre la cible et la source reconnue.
