8 . The roof construction according to claim 6 , wherein the cable attachment elements are formed by hooks, wherein the hooks are L-shaped or C-shaped hooks, wherein at least some of the hooks are at a distance from (d 1 ) the spine that is greater than 20% greater than the thickness of the cable.
9 . The roof construction according to claim 1 , wherein the cable guides have first attachment elements at the ends and that the transverse elements are equipped with two attachment elements, wherein the first of the two attachment elements together are provided for the attachment of the cable guides to the transverse elements.
10 . The roof construction according to claim 9 , wherein the first and second attachment elements comprise interlocking male and female elements.
11 . The roof construction according to claim 10 , wherein the female elements are formed by one or more grooves and the male elements by one or more hooks that together form a click connection.
12 . The roof construction according to claim 1 , wherein the cable guides are integrally made, using injection molding, of plastic, wherein the pastic is a thermoplastic such as polyvinyl chloride (PVC), polyamide (PA), polyethylene (PE) or polypropylene (PP) or an elastomer such as rubber, wherein the rubber is a thermoplastic elastomer or composite materials, wherien the composite materials are fiber-reinforced plastics such as fiberglass reinforced plastic.
13 . The roof construction according to claim 1 , wherein the ends of the cable guides are attached to the support elements.
14 . The roof construction according to claim 13 , wherein there is a distance between the ends of the slats and the cable guides in the stacked position of the transverse elements.
15 . The roof construction according to claim 1 , wherein at least one slat has at least one electrical component that is equipped with power via a power cable attached in the cable guides.
16 . The roof construction according to claim 1 , wherein the roof construction also has the cable which is attached in the cable guide.
17 . The roof construction according to claim 1 , wherein the roof construction has an additional cable guide attached between the frame and one transverse element, wherein the additional cable guide together with the other cable guides form a cable guide for encompassing the cable from the frame to at least one of the transverse elements.
