In a structural component (1), a shielding component in particular, with individual adjacent component sections (21, 23) that can be brought at least partially by a functional unit (25) into a definable three-dimensional position to each other along an action line. The functional unit (25) is divided into component units (27, 29, 31) enabling definable positioning along at least one further action line (29) extending at a definable distance adjacent to one action line (27).
