摘要

The mat has a folding line (4), and two areas (5, 6) foldable on top of each other in opposite directions by the folding line. The folding line is formed by thermal deformation, and includes a U-profile in a cross section. An upper layer (2) and a lower layer are provided, where the upper layer lies above the lower layer. The upper layer is thermally welded with the lower layer running at outer edges (3).
