Wiper blade

摘要

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).

主权项

1. A wiper blade (10) with a supporting bracket system which is connectable to a wiper arm in an articulated manner, the wiper blade (10) comprising:
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 a region of at least one joint (20, 26), the superordinate bracket (12, 24) has a U-shaped cross sectional profile, side walls (18, 44) of which laterally enclose the subordinate bracket (24, 28), and, on 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 at least one of the superordinate bracket and the subordinate brackets 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), wherein the superordinate bracket (12, 24) has demolding holes (48) in the region of its pivots (50) in its top wall (58), and wherein lateral edges of the subordinate bracket (24, 28), which edges face the top wall (58) of the superordinate bracket (12, 24), have installation slopes (40).
