A roller blind for windows and doors, comprising curved profile strips which are hingedly connected to and in parallel with each other, wherein two interlocking profile strips have clamped therebetween flexible hinge straps which extend in a direction vertical to said profile strips and connect said strips to each other in the vertical direction and wherein said hinge straps are clamped between said interlocking profile strips in vertical direction next to each other and in overlapping fashion.

A roller blind comprising:

• at least two adjacent pairs of curved profile strips, each member of each pair being adjacent to and parallel to the other member of such pair, one member of each pair having an exposed side and an unexposed side;
• and
• a flexible strap having two sides, the strap sandwiched between the members of each pair of curved profile strips, wherein the exposed surface area of the exposed side of the profile strip member is greater than the exposed surface area of one side of the strap between adjacent pairs of profile strips.

A roller blind for windows and doors, comprising at least two curved profile strips which are hingedly connected to and in parallel with each other, wherein a pair of interlocking profile strips have clamped therebetween continuous flexible discrete hinge straps which extend in a direction vertical to said profile strips and connect said strips to each other in the vertical direction, wherein the profile strips are broader than the hinge straps, and wherein each discrete hinge strap is clamped between more than two pairs of interlocking profile strips.
