摘要

Covering has rectangular upper surface (1) and lower surface (2), which are connected such that a gap (3) develops between upper and lower surface in longitudinal side. Upper and lower surface exhibits a continuous bent section (4) at the longitudinal sides, which leads to partial, lowered surfaces (5), which run parallel to the upper and lower surface and lead to an intermediate tapered gap (6) within this implemented range.
