Claims

1. A protection device for protecting an object against a rocket propelled grenade comprising a grid configuration comprising at least two essentially mutually parallel running profile elements arranged to affect the electric detonation release arrangement of the grenade by short-circuiting, wherein said profile elements each have a cross section being tapering in a principal incoming direction of the grenade to have a tapering end, and wherein the cross section of the profile element has a corner portion facing the principal incoming direction, the corner portion has an acute angle, and the corner portion is different from the tapering end, and wherein the tapering end is an end facing the protected object and the corner portion is at an end opposite from the tapering end.
2. A protection device according to claim 1, wherein said profile elements are each arranged to run essentially horizontally.
3. A protection device according to claim 1, wherein the corner portion projects towards said principal incoming direction.
4. A protection device according to claim 3, wherein the acute angle of said projecting corner portion is created by forming a recess facing said principal incoming direction.
5. A protection device according to claim 4, wherein said recess has an essentially arc-shaped cross section.
6. A protection device according to claim 1, wherein the cross section of said profile elements comprises an essentially horizontally running side and a side running with an angle towards that.
7. A protection device according to claim 1, wherein the cross section of said profile elements comprises two opposite sides, each forming an angle to the horizontal plane.
8. A protection device according to claim 1, wherein adjacent profile elements of said grid configuration forms a minimum space which is smaller than the greatest thickness of the grenade at said electric detonation release arrangement.
9. A vehicle comprising a protection device according to claim 1.
10. A protection device according to claim 1, wherein the tapering end is configured to face an object to be protected by the protection device.
