Slat for a slatted roof or a slatted window, and a slatted roof or slatted window having such a slat

A slatted roof (20) with a supporting structure (21) and slats (1) arranged parallel to each other, which are fitted to the supporting structure (21) in such a way that they can each be rotated around a respective rotational axis (5) which runs along their longitudinal extent in order to pivot the slats (1) between a closed position and an open position,

• wherein the slats (1) each have a transparent, flat covering element (2) with a longitudinal extent, two longitudinal sides (2a, 2b) running along the longitudinal extent, and a width (b), the width (b) being shorter than the longitudinal extent, and each slat (1) also having at least one partially opaque, flat shading element (6) with a corresponding longitudinal extent and a corresponding height (h), the corresponding longitudinal extent of which extends along at least part of the length of the longitudinal extent of the transparent, flat covering element (2), and which is fixed to the transparent, flat covering element (2) with a first longitudinal side (6a), and a second longitudinal side (6b) of the at least one partially opaque, flat shading element (6) opposite the first longitudinal side (6a) protrudes from the transparent, flat covering element (2),
• wherein the at least one partially opaque, flat shading element (6) is positioned in its areal extent at an angle (α) with respect to a corresponding areal extent of the transparent, flat covering element (2),
• wherein the transparent, flat covering elements (2) of the slats (1) have a sealing profile (23a;
• 23b;
• 2c) on at least one of their first and second longitudinal sides (2a, 2b),
• wherein the position of the partially opaque, flat shading elements (6) on transparent, flat covering elements (2), and the corresponding height (h) of the partially opaque, flat shading elements (6), and the width (b) of the transparent, flat covering elements (2), are coordinated in such a way that the slats (1), from a first closed position, in which sealing profiles (23a) on corresponding first longitudinal sides (2a) of the transparent, flat covering elements (2) of the slats (1) interlock with corresponding sealing profiles (23b) on corresponding second longitudinal sides (2b) of the transparent, flat covering elements (2) of their respective neighboring slats (1), or
• in which lip seals (2c) running along the corresponding first longitudinal sides (2a) and/or the corresponding second longitudinal sides (2b) of the transparent, flat covering elements (2) of the slats (1) lie on the corresponding second longitudinal sides (2b) or on the corresponding first longitudinal sides (2a) of the transparent, flat covering elements (2) of their respective neighboring slats (1), and the partially opaque, flat shading elements (6) are fixed to an outer side of the transparent, flat covering elements (2) and protrude upwards from them, can be rotated around their rotational axes (5) into a second closed position in which the corresponding second longitudinal sides (6b) of the partially opaque, flat shading elements (6) of the slats (1) are in contact with the corresponding sealing profiles (23b) on the corresponding second longitudinal sides (2b) of the transparent, flat covering elements (2) of their respective neighboring slats (1).
