Abstract

An adapter (38, 66) for the articulated connection of a wiper blade (24) to a wiper arm (10) using the sidelock system, wherein the adapter (38, 66) has an essentially cylindrical longitudinally slotted bearing element (40, 68), which can be inserted into passages (34) in side walls (30) of a suspension box (28) of the wiper blade (24) and can be fixed on a first end on the edge of a passage (34) by means of locking hooks (50), while its second end is connected with a bearing surface (54, 78), which is adjacent to the outer side of the opposing side wall (30) and is secured against twisting by at least one clip (58, 80). The clip (58, 80) has a locking nose (60), which points in the direction of the bearing element and locks on an edge of the coordinating side wall (30) of the suspension box (28) during assembly.

Claims

1. Adapter (66) for the articulated connection of a wiper blade (24) to a wiper arm (10) using a sidelock system, wherein the adapter (66) has an essentially cylindrical longitudinally slotted bearing element (68), which can be inserted into passages (34) in side walls (30) of a suspension box (28) of the wiper blade (24) and can be fixed on a first end on the edge of a passage (34) in one side wall (30) by means of locking hooks (50), while a second end of the bearing element (68) is connected with a bearing surface (78), which is adjacent to the outer side of an opposing side wall (30) and is secured against twisting by at least one clip (80), characterized in that the clip (80), has a locking nose (60), which points toward the bearing element (68) and locks on an edge of the opposing side wall (30) of the suspension box (28) during assembly, characterized in that the second end is formed on a cap (76), whose bearing surface (78) is adjacent to the coordinating side wall (30) in an assembled state and which features at least one clip (80), and characterized in that the cap (76) has recesses (84) on the side of the bearing element (68) and in an assembled state it externally covers the passages (34) and an articulated bolt (32).

2. Adapter (66), according to claim 1, characterized in that the cap (76) has a bearing surface (82) on its outer side for a bent end (14) of a bridge (12) of the wiper arm (10).

3. Adapter (66) for the articulated connection of a wiper blade (24) to a wiper arm (10) using a sidelock system, wherein the adapter (66) has an essentially cylindrical longitudinally slotted bearing element (68), which can be inserted into passages (34) in side walls (30) of a suspension box (28) of the wiper blade (24) and can be fixed on a first end on the edge of a passage (34) in one side wall (30) by means of locking hooks (50), while a second end of the bearing element (68) is connected with a bearing surface (78), which is adjacent to the outer side of an opposing side wall (30) and is secured against twisting by at least one clip (80), characterized in that the clip (80), has a locking nose (60), which points toward the bearing element (68) and locks on an edge of the opposing side wall (30) of the suspension box (28) during assembly, characterized in that the second end is formed on a cap (76), whose bearing surface (78) is adjacent to the coordinating side wall (30) in an assembled state and which features at least one clip (80), characterized in that the cap (76) has a bearing surface (82) on its outer side for a bent end (14) of a bridge (12) of the wiper arm (10), and characterized in that the cap (76) has recesses (84) on the side of the bearing element (68) and in an assembled state it externally covers the passages (34) and an articulated bolt (32).
