Protective device for armored vehicles, particularly for protecting against hollow-charge projectiles

Abstract

A protective device for protecting armored vehicles from hollow-charge projectiles includes at least one protective module that is mounted in front of the exterior of a wall to be protected. The protective module is moved out of an inoperative position, in which it is situated in a predetermined position, and into an active position, in which at least partial areas of the protective module have a greater distance from the wall to be protected compared to the inoperative position. The protective module can be constructed from a number of components, which can be displaced relative to one another and which, as a result of a displacing motion and/or pivotal motion, can be displaced out of the inoperative position and into the active position in which they are interlocked.

       19 . A protective device for armored vehicles for protection against hollow-charge projectiles, comprising: 
 at least one protective module mounted in front of a wall to be protected, wherein the at least one protective module is moveable from an inoperative position, in which the at least one protective module is disposed in a fixed, predetermined position, into an active positive, wherein in the active position at least partial areas of the at least one protective module have a greater distance from the wall to be protected than when in the inoperative position.    
   
   
       20 . The protective device of  claim 19 , wherein the at least one protective module comprises a fixedly assembled component and is moveable from the inoperative position into the active position in a linear direction running essentially orthogonally to the wall to be protected.  
   
   
       21 . The protective device of  claim 19 , wherein the at least one protective module comprises multiple components that are moveable relative to one another, wherein said components are moveable, respectively, in a displacing and/or pivoting motion from the inoperative position into the active position, and wherein in the active position, the components are interlocked with one another.  
   
   
       22 . The protective device of  claim 21 , wherein the at least one protective module comprises two plate elements, wherein the plate elements are pivotable relative to one another about pivot axes, wherein said pivot axes are disposed to be parallel to one another and parallel to the wall to be protected, wherein the plate elements are designed and disposed in such a manner that in the inoperative position, the plate elements are layered on top of one another and disposed parallel to one another and to the wall to be protected, wherein during movement into the active position, each plate element is vertically pivotable about a predetermined angle, and wherein pivoting movements of the plate elements run in opposite directions, such that in the active position, edges of the plate elements facing away from the pivot axes are adjacent one another and upon reaching the active position, the plates interlock into one another.  
   
   
       23 . The protective device of  claim 21 , wherein the components of the at least one protective module are moveable from a first active position, in which they interlock in one another, into a second active position in a linear direction running essentially orthogonally to the wall to be protected, wherein in the second active position, at least partial areas of the at least one protective module have a greater distance from the wall to be protected than in the first active position.  
   
   
       24 . The protective device of  claim 19 , wherein the at least one protective module is moveable back from the active position into the inoperative position.  
   
   
       25 . The protective device of  claim 23 , wherein movements of the at least one protective module from the inoperative position into the first and/or second active position and/or back into the inoperative position take place by means of a drive device.  
   
   
       26 . The protective module of  claim 25 , wherein the drive device is a mechanical drive device.  
   
   
       27 . The protective module of  claim 25 , wherein the drive device is an electrical or mechanical drive device.  
   
   
       28 . The protective device of  claim 25 , wherein the drive device is a hydraulic drive device.  
   
   
       29 . The protective device of  claim 25 , wherein the drive device is a pneumatic drive device.  
   
   
       30 . The protective device of  claim 23 , wherein movement of the at least one protective module from the inoperative position into the first and/or second active position take place via pyrotechnical means.  
   
   
       31 . The protective device of  claim 21 , wherein the components that are moveable relative to one another are sandwich-like, multiple layers of plates.  
   
   
       32 . The protective device of  claim 19 , wherein the at least one protective module is formed as a buckling sheet louver with a plurality of layers arranged inclined to the wall to be protected.  
   
   
       33 . The protective device of  claim 19 , comprising first and second protective modules, wherein the second protective module is fixedly disposed between the first protective module that is moveable from a inoperative position into at least one first position and the wall to be protected.  
   
   
       34 . The protective device of  claim 33 , wherein the first protective module is formed as protection against hollow-charge projectiles and the second protective module is formed as protection against impact projectiles.  
   
   
       35 . The protective device of  claim 33 , wherein at least one of the first and second protective modules is formed as passive plating.  
   
   
       36 . The protective device of  claim 33 , wherein at least one of the first and second protective modules is formed as reactive plating.
