Roller blind assembly and kit

A kit for a roller blind assembly that is securable between a first support bracket and a second support bracket, the second support bracket horizontally spaced apart from the first support bracket, the roller blind assembly comprising:

• I) a roller tube extending longitudinally from a first end to a second end, the roller tube comprising longitudinally extending first and second grooves, wherein the first and second grooves are circumferentially spaced apart from each other;
• II) a connector configured to secure the first end of the roller tube to the first support bracket;
• III) an actuator configured to secure the second end of the roller tube to the second support bracket;
• and
• IV) a blind configured to be supported by the roller tube, the blind comprising:
• a bottom rail;
• and
• a blind material comprising a first edge configured to be secured to the first groove, and a second edge opposite the first edge configured to be secured to the second groove, the blind material comprising a plurality of first and a plurality of second strips, wherein each of the first strips alternates with each of the second strips, the plurality of first strips having a lower light transmissibility than the plurality of second strips, wherein, when the blind material is secured to the roller tube, the blind material defines superposed front and rear blind segments, the front blind segment extending from the first edge to the bottom rail, the rear blind segment extending from the second edge to the bottom rail,
• wherein rotation of the roller tube in a first direction unwinds the front and rear blind segments from the roller tube, and rotation of the roller tube in a second direction opposite the first direction winds the front and rear blind segments onto the roller tube.
