Claim:
An offset ballistic protection device ( 101 ) protecting a wall ( 100 ) provided with a hatch ( 200 ), wherein said device ( 101 ) comprises: at least a first grid ( 1 ) offset with respect to the wall ( 100 ) and connected thereto, wherein the first grid ( 1 ) comprises a first series of bars ( 1 a ) parallel to each other, wherein a first end of the first series of bars ( 1 a ) is in the vicinity of a hinge ( 300 ) of the hatch ( 200 ), wherein the first series of bars ( 1 a ) is substantially perpendicular to the pivot axis ( 400 ) of the hinge ( 300 ), a second grid ( 2 ) offset with respect to the hatch ( 200 ) and connected thereto, wherein the second grid ( 2 ) comprises a second series of bars ( 2 a ) substantially parallel to the first series of bars ( 1 a ), wherein the second grid ( 2 ) is positioned with respect to the first grid ( 1 ) so that the bars ( 2 a ) of the second grid ( 2 ) are spatially offset in the plane of the second grid ( 2 ) with respect to the bars ( 1 a ) of the first grid, wherein the bars ( 2 a ) of the second grid ( 2 ) are therefore able to pass between the bars ( 1 a ) of the first grid ( 1 ) during pivoting of the hatch ( 200 ).
