Roller blind system for straight and curved window segments

A roller blind assembly configured for deployment along a curved window segment, the roller blind assembly comprising:

• a housing having a hollow body formed within a longitudinal passageway;
• the longitudinal passageway having a gap along a lower margin thereof;
• the housing being fixed to one of a ceiling and a wall;
• a guide mounted to one of the ceiling and the wall adjacent to the curved window segment;
• a profile of the guide conforming to a curved profile of the curved window segment;
• the guide having a guide channel;
• the guide channel having a gap along a lower margin thereof and being aligned with the longitudinal passageway;
• a flexible toothed gear rack configured to be received within the longitudinal passageway and the guide for lateral displacement relative thereto;
• the toothed gear rack having an upper portion and a lower portion;
• the upper portion formed with spaced apart teeth;
• a drive assembly mounted within the hollow body of the housing, the drive assembly including a motor, a worm operatively connected to the motor and a toothed worm wheel configured to engage the teeth formed on the upper portion of the toothed gear rack to urge lateral displacement of the toothed gear rack relative to the longitudinal passageway and the guide;
• and
• a blind attached to a lower portion of the toothed gear rack;
• the toothed gear rack being movable laterally between a fully retracted position and fully extended position,
• when the toothed gear rack is in the fully retracted position:
• the toothed gear rack is contained within the longitudinal passageway;
• the blind protrudes from the gap in the lower margin of the longitudinal passageway;
• and
• the curved window segment remains uncovered by the blind;
• when the toothed gear rack is in the fully extended position:
• a majority portion of the toothed gear rack is contained within the guide;
• the blind protrudes from the gap in the lower margin of the guide channel;
• and
• the curved window segment is covered by the blind.
