Wiper blade structure of wiper blade used for wiping windscreen of e.g. motor car, has side unit that is provided with torsion elements so as to increase torsional rigidity of spring element

摘要

The wiper blade structure comprises resilient spring elements (10a,32a) and a side unit (12a). The side unit is provided with torsion elements (14a,14a') so as to increase torsional rigidity of spring element. The side unit is provided with end element (16a). The end element is inseparably connected with torsion element. The torsion element is connected with spring element. Independent claims are included for the following: (1) wiper blade; and (2) method for manufacturing wiper blade element.
