Patent ID: 7640733

Claim:
A shielding component, comprising: first, second, third and fourth structural parts having different configurations in at least one of surface extent and pattern; said first structural part being symmetrical in longitudinal and transverse directions, having a curvature at least partially increasing in a direction of two transversely opposite curved edge areas thereof, having a middle area of lesser curvature extending between said edge areas, and having a plane of symmetry forming a right angle with an imaginary chord of an arc formed by a cross section of said first structural part; said second structural parts at least partially following said curvature of said first structural part and positioned at least outside of connecting points to extend continuously along said first structural part; said third structural parts extending continuously in said curved edge areas in areas of change in said curvature toward said edge areas along said first structural part according to positioning of said second structural parts; and at least one said fourth structural part connecting between said second structural parts, having a surface extent smaller than or equal to a surface extent of one of said second structural parts, and extending along a central longitudinal axis of said first structural part.
