Multi-segment retractable curtain with universal connector

A multi-curtain assembly having a plurality of curtain segments of a retractable curtain, positioned in a structure, the curtain segments having leading edges affixed to a bottom bar and configured to extend between opened and closed positions by winding on and unwinding from a barrel assembly, each curtain segment being optionally connectable to the other curtain segment adjacent thereto by a fastener at respective adjacent edges of each curtain segment during unwinding, the multi-curtain assembly comprising:

• a motor driving the barrel assembly of a first one of said plurality of curtain segments, adjacent and further ones of said plurality of curtain segments meeting one another at an interface angle;
• and
• at least one curtain driving interface configured to pass along a rotational barrel driving force from the barrel assembly of the first one of said plurality of curtain segments;
• the driving interface being one selected from the group consisting of:
• (a) an interface for an interface angle of 90 degrees;
• (b) an interface for an interface angle of less than 90 degrees;
• (c) an interface for an interface angle of greater than 90 degrees;
• and
• (d) an interface where one barrel assembly is at a height that is different from another barrel assembly.
