A sun blind comprising a trip arm formed by two pivotally intercoupled arm parts (4) and (5) and being fastened by one end with the aid of an upwardly extending pivotal shaft to a supporting structure, whereas the other end is fastend to a cloth beam, the two arm parts (4) and (5) being also pivotally coupled with one another with the aid of an upwardly extending pivot axis in a manner such that the two arm parts (4) and (5) are at an obtuse angle to one another. Thereby the arm parts (4) and (5) are made from hollow profiles and into the proximal ends of the arm parts (4) and (5) are inserted coupling members which partly protrude out of the arm parts (4) and (5). Said coupling members are obtained by severing them from an extrusion profile separation planes transverse of the direction of length of the extrusion profile, whilst the portions of the coupling members lying outside the arm parts (4) and (5) have holes extending between the separation planes and being at an angle differing from 90 DEG to the separation planes. |
