4 . The roller-blind device according to claim 3 , wherein at least one of the first strut and the second strut is movable to unroll and roll the at least one of first flexible flat structure and the second flexible flat structure from and onto the roller-blind axis.
5 . The roller-blind device according to claim 3 , wherein the first strut or the second strut is mounted fixed in place, and the roller-blind axis is movable to unroll and roll at least one of the first flexible flat structure and the second flexible flat structure from and onto the roller-blind axis.
6 . The roller-blind device according to claim 1 wherein the first flexible flat structure and the second flexible flat structure have a net-like material.
7 . A wind deflector for motor vehicle having a roller-blind device according to claim 1 .
8 . The wind deflector according to claim 7 , further comprising a stretching bow operatively mounted to be pivotable around a first pivot axis oriented in a transverse direction of the motor vehicle and fixed in place, and a roof arch operatively mounted to be pivotable around a second pivot axis extending in the transverse direction of the motor vehicle and fixed in place, the second pivot axis being spaced from the pivot axis as viewed in a longitudinal direction of the motor vehicle wherein the roller-blind axis is operatively associated at the roof arch parallel to the second pivot axis.
9 . The wind deflector according to claim 8 , wherein the roller-blind axis is implemented on a transverse web of the roof arch extending parallel to the second pivot axis.
10 . The wind deflector according to claim 9 , wherein the first flexible flat structure is operatively fastened to the stretching bow, and the second flexible flat structure is operatively fastened and fixed in place to a rear area of the motor vehicle.
11 . The wind deflector according to claim 10 , wherein a front edge of the first flexible flat structure and a front edge of the second flexible flat structure are operatively attached to the roller-blind axis and another front edge of the first flexible flat structure is operatively attached to a transverse web of the stretching bow and another front edge of the second flexible flat structure is operatively attached fixed in place to the motor vehicle.
12 . A motor vehicle having a roller-blind device according to claim 1 .
13 . The motor vehicle according to claim 12 , wherein the motor vehicle has a transparent area, and the roller-blind device is configured and arranged so that it at least partially covers a transparent area in an active position of the roller blind device.
14 . The motor vehicle according to claim 13 , wherein the transparent area has a glass area.
15 . The motor vehicle according to claim 13 , wherein a roof of the motor vehicle includes the transparent area.
16 . The motor vehicle according to claim 15 , wherein the roller-blind axis is implemented on a roof spar of the roof.
17 . The motor vehicle according to claim 12 , wherein the roller-blind device is configured and arranged so as that the first flexible flat structure is unrollable from the roller-blind axis in a direction of a windshield and the second flexible flat structure is unrollable in a direction of a rear area of the motor vehicle.
18 . The motor vehicle according to claim 17 , wherein one front edge of the first flexible flat structure and one front edge of the second flexible flat structure are attached to the roller-blind axis and another front edge of the first flexible flat structure is attached to a first, movable strut and another front edge of the second flexible flat structure is attached to a second, movable strut.
