A roller blind for skylights, having a roller blind compartment (4) which can be fitted on the upper part of the blind, a winding shaft (6) rotatably mounted in the compartment and a strap drum (8) coaxially connected, for joint rotation, to the winding shaft for a pulling strap (9), has a plurality of strap deflecting elements (10, 11, 12 13) arranged in the roller blind compartment (4), which elements deflect the pulling strap (9), extending from the strap drum (8), with axial strap twisting, firstly substantially parallel to the winding shaft (6), then substantially parallel to the central plane of the strap drum and then substantially perpendicular to the plane of exit of the roller blind toward the window, whence, in the installed position, it runs through a strap opening (3a) in the outer covering of the frame upper piece between the latter and a cover part engaging underneath its outer covering directly to a strap winder, preferable fitted above the window.

A roller blind for use with skylights mounted on a roof, said roller blind having a frame upper piece, an outer covering, a roller blind compartment which can be fitted on the upper part of the blind, a winding shaft rotatably mounted in the compartment and a strap drum coaxially connected to the winding shaft for a pulling strap leading to the inside of the room and connected if necessary to a strap winder, wherein there are arranged (a) in the roller blind compartment (4) at least a first strap deflecting element (10) for deflection of the pulling strap (9) leaving the strap drum (8) into a direction substantially parallel to the winding shaft (6), and (b) at least a second strap deflecting element (11) for further deflection of the pulling strap (9) into a direction substantially parallel to the central plane of the strap drum (8), and (c) at least a third strap deflecting element (13) is provided for deflection of the pulling strap (9) into a direction running outward from the window substantially perpendicular to the exit plane of the roller blind (7) from the roller blind compartment (4), said strap deflecting element (13) being mounted on the roller blind compartment (4) spaced from said first strap deflecting element to a point proximate to the frame upper piece (1) so that the pulling strap (9) can, in the installed position, be led inward through a strap opening (3a), made in said outer covering (3) of a frame upper piece (1), said pulling strap being located between said frame upper piece (1) and a cover part (2) said cover part being partially disposed between said outer covering (3) and said frame upper piece thereby avoiding passing of the strap through the roof and the inherent sealing problems associated therewith.
