Shade device for a transparent roof element

Shade device for roof elements of motor vehicles, comprising:

• a first winding shaft with a first fabric shade which can be wound onto and off of the first winding shaft,
• a first draw bar which is movable in winding and unwinding directions of the first fabric shade and which is located on a free end of the first fabric shade,
• a first draw cable arrangement which acts in a pull-out direction of the first shade and which engages the first draw bar via a single draw cable,
• a first reset spring which is connected to the winding shaft and which is adapted to be tensioned when the first fabric shade is pulled out,
• a second winding shaft with a second fabric shade which can be wound onto and off of the second winding shaft,
• a second draw bar which is movable in winding and unwinding directions of the second fabric shade and which is located on a free end of the second fabric shade,
• a second draw cable arrangement which acts in a pull-out direction of the second shade and which engages the second draw bar via a single draw cable,
• a second reset spring which is connected to the second winding shaft and which is adapted to be tensioned when the second fabric shade is pulled out,
• a drawing mechanism for actuating all of the shades at the same time,
• wherein the draw cables of the draw cable arrangements are attached at one end to separate, shade-specific fixed points and at another end being wound onto separate, shade-specific drum sections which are located next to one another on a drive shaft of the drawing mechanism, and
• wherein the shade-specific drum sections have respective winding diameters (b1, b2) which are matched to respective pull-out lengths (a1, a2) of the shades such that the shades are movable at the same time into open and closed positions thereof by the drive shaft of the drawing mechanism.
