Roller blind

摘要

The blind (2) has a set of lamellas (3) movable from a closely together lying position for completely shading into easily pulled apart position for a partial light exposure. The lamellas are connected with each other over spring units (8), where distance of the lamellas is changeable among themselves. A traction mechanism is provided for pulling apart the lamellas against force of the spring units. The spring force of the spring units is determined in such a manner that the spring force is larger than weight force of the lamellas.
