WIPER BLADE
First Claim
1. A wiper blade (10) with a supporting bracket system which can be connected to a wiper arm in an articulated manner and comprises at least one superordinate bracket (12, 24) and a plurality of subordinate brackets (24, 28) which are connected pivotably to one another by joints (20, 26), wherein, in the region of at least one joint (20, 26), the superordinate bracket (12, 24) has a U-shaped cross sectional profile, the side walls (18, 44) of which laterally enclose the subordinate bracket (24, 28), and, on the insides of the side walls (44), has pivots (50) which, together with lateral clip cutouts (54) on the subordinate bracket (28), form a clip connection and a bearing point while the subordinate bracket (28) is supported via a rolling bearing (34, 66) on a top wall (58) of the superordinate bracket (24), characterized in that the pair of brackets (12, 24 or 24, 28) which is interconnected in an articulated manner in this way is manufactured from plastic by injection molding, with the pivots (50) being integrally cast on the insides of the side walls (18, 44) of the superordinate bracket (18, 24).

Abstract
The invention is based on a wiper blade (10) with a supporting bracket system which can be connected to a wiper arm in an articulated manner and has at least one main bracket (12, 24) and a plurality of secondary brackets (24, 28) which are connected pivotably to one another by means of joints (20, 26), wherein, in the region of at least one joint (20, 26), the main bracket (12, 24) has a U-shaped cross-sectional profile, the side walls (18, 44) of which laterally enclose the secondary brackets (24, 28), and, on the insides of the side walls (44), has pivots (50) which, together with lateral clip cutouts (54) on the secondary bracket (28), form a clip connection and a bearing point, while the secondary bracket (28) is supported via a rolling bearing (34, 66) on a top wall (58) of the main bracket (24). It is proposed that the pair of brackets (12, 24 or 24, 28), which in this way are connected to each other in an articulated manner, is manufactured from plastic in an injection-moulding process, with the pivots (50) being integrally cast on the insides of the side walls (18, 44) of the main bracket (18, 24).
