Window curtain for covering and uncovering of sunroof of car, has shaft element rotated in rotation directions so that outer projection of pressing element lies at inner projection of tube element to unwind cords from spools

摘要

The curtain has a coupling unit (54) allowing rotation of a shaft element (43) in a rotation direction of the unit to couple the element and spools (55), so that each cord (65) is wounded on the spools to rotate a tube element. The shaft element is rotated in another rotation direction so that the unit loosens the shaft element and the spools, and an outer projection of a pressing element lies at an inner projection of the tube element to rotate the tube element, wind a screen body (61) on the tube element, rotate the spools and unwind the cords from the spools.
