Sun or weather protection installation, comprising: - A bearing frame delimiting a deployment surface and comprising at least two guide rails, referred to as the first guide rail and the second guide rail, which are parallel to each other and to a direction referred to as the deployment direction, - A series of slats arranged parallel to each other, each slat extending along a longitudinal axis perpendicular to the deployment direction and having two ends each slidingly mounted in a separate guide rail, - A first translational drive system, designed to move the slats in translation in the deployment direction by sliding in the two guide rails, between at least one retracted position in which the slats are contiguous with each other and a deployed position in which the slats are deployed over the entire deployment surface, - A second pivoting drive system, designed to pivot each slat about its longitudinal axis between at least two distinct orientations, - The second pivoting drive system comprising pivoting members fastened to at least said first guide rail and distributed along said first guide rail, each slat being intended to slide along the two guide rails to a position in which one of its two ends cooperates with a separate pivoting member, - Each pivoting member being mounted fixed in translation on said first guide rail and pivotable to pivot a slat about its longitudinal axis when cooperating with the end of said slat, - The first translational drive system including at least one motor controlled to drive at least one slat, referred to as the head slat (2_1), and in that the slats are connected to each other by means of jointed connecting members, - Characterized in that: - The second pivoting drive system comprises at least one cylinder on which is mounted a transmission bar which can be moved in translation by said cylinder, each pivoting member of the first guide rail being connected to said transmission bar via a connecting rod, which is used to transform the translational movement of the transmission bar into a rotational movement of the pivoting member. - A bearing frame delimiting a deployment surface and comprising at least two guide rails, referred to as the first guide rail and the second guide rail, which are parallel to each other and to a direction referred to as the deployment direction, - A series of slats arranged parallel to each other, each slat extending along a longitudinal axis perpendicular to the deployment direction and having two ends each slidingly mounted in a separate guide rail, - A first translational drive system, designed to move the slats in translation in the deployment direction by sliding in the two guide rails, between at least one retracted position in which the slats are contiguous with each other and a deployed position in which the slats are deployed over the entire deployment surface, - A second pivoting drive system, designed to pivot each slat about its longitudinal axis between at least two distinct orientations, - The second pivoting drive system comprising pivoting members fastened to at least said first guide rail and distributed along said first guide rail, each slat being intended to slide along the two guide rails to a position in which one of its two ends cooperates with a separate pivoting member, - Each pivoting member being mounted fixed in translation on said first guide rail and pivotable to pivot a slat about its longitudinal axis when cooperating with the end of said slat, - The first translational drive system including at least one motor controlled to drive at least one slat, referred to as the head slat (2_1), and in that the slats are connected to each other by means of jointed connecting members, - Characterized in that: - The second pivoting drive system comprises at least one cylinder on which is mounted a transmission bar which can be moved in translation by said cylinder, each pivoting member of the first guide rail being connected to said transmission bar via a connecting rod, which is used to transform the translational movement of the transmission bar into a rotational movement of the pivoting member.
