Definitions

  • the invention relates to a protective structure for an armored vehicle or object, which is externally frictionally connectable at least in some areas with a basic structure of the armored vehicle.

  • the invention has for its object to provide a protective structure for armored vehicles, which is easy to manufacture and large-scale attachable to the vehicle and has a low weight.

Abstract

L'invention concerne une structure de protection (3) pour un véhicule blindé, laquelle peut être reliée à force, au moins dans des zones partielles, côté extérieur, à une structure de base (1) du véhicule blindé. L'invention vise à obtenir une structure de protection (3) pour des véhicules blindés pouvant être fabriquée en toute simplicité et présentant un poids modéré. À cet effet, l'invention propose d'utiliser, pour la structure de protection (3), plusieurs éléments de protection (8) réalisés de manière à présenter une forme plate, lesquels comportent respectivement une structure en sandwich en mousse de métal (9), en particulier une structure en sandwich en mousse d'aluminium.
