2131466 9318827 PCTABS00025 The surface element is intended for formation of a gliding surface e.g. in a down-slope or the like. The surface element (e) comprises a substantially transverse frame unit (1), a gliding unit (3) and a supporting unit (4). The frame unit (1) is equipped with attaching means (2) for attaching the surface element (e) into a base (A). The gliding unit (3) comprises several flexible gliding means (3a) attached to the joining point (L) of the frame unit (1), such as fibres, strings, threads or the like. The supporting unit (4) comprises at least one supporting surface (4a) connected with the frame unit (1) and continuously supporting the gliding unit (3) of the surface element substantially in the longitudinal direction (s). The supporting unit (4) of the surface element (e) is arranged in connection with the frame unit (1) in a way that in the coating formed of several successive surface elements (e1, e2, e3) in the longitudinal direction (s), the supporting unit (4) of the next surface element (e2, e3) forms the supporting surface (4a) supporting the gliding unit (3) of at least one preceding surface element (e1, e2). |
