Abstract

The invention relates to a device (20) for connecting a wiper blade (12) to a wiper arm (10) of a windshield wiper in an articulated manner, which comprises a joining element (38), which is joined in a fixed manner to the wiper arm (10), and a connecting element (22), which is joined in a fixed manner to a supporting element (16) of the wiper blade (12) and on which a plastic adapter (30) is pivotally mounted. The adapter (30) is fixed in the profile of the joining element (38), said profile being open toward the connecting element (22), by means of fastening means (34, 40). The invention provides that a filler piece (44) is placed in the joining element (38) on the side facing the wiper arm (10) following the adapter (30). Said filler piece rests tightly against the inside walls of the joining element (38) and against the adjacent face of the adapter (30).

Claims

1. Device (20) for the articulated connection of a wiper blade (12) to a wiper arm (10) of a windshield wiper, the device comprising a connecting element (38), which can be connected to a connecting piece (22) of the wiper blade (12) and which has a profile that is open towards the connecting piece (22), characterized in that a filler piece (44) is arranged in the connecting element (38) on a side facing the wiper arm (10), which filler piece tightly abuts inner walls of the connecting element (38), and characterized in that an adapter (30) is fixed against pivotal and translational movement relative to the connecting element via fastening means (34, 40) in the profile of the connecting element (38) that is open towards the connecting piece (22), and the adapter can be pivoted on the connecting piece (22), and wherein the filler piece (44) is arranged following the adapter (30) and tightly abuts an adjacent face of the adapter (30).

2. Device (20) according to claim 1, characterized in that the filler piece (44) is adjacent with at least one rim (46) to an edge (47) on the open side of the connecting element (38).

3. Device (20) according to claim 1, characterized in that the face of the adapter (30) that is adjacent to the filler piece (44) engages in an overlapping manner in recesses (50, 52, 54) on an adjacent face (48) of the filler piece (44).

4. Device (20) according to claim 1, characterized in that a bulkhead wall (60) that runs transverse to a longitudinal axis of the wiper blade (12) is provided on a drive side of the connecting piece (22), which bulkhead wall engages in a slot (58) of the filler piece (44) with little play.

5. Device (20) for the articulated connection of a wiper blade (12) to a wiper arm (10) of a windshield wiper, the device comprising a connecting element (38), which can be connected to a connecting piece (22) of the wiper blade (12) and which has a profile that is open towards the connecting piece (22), characterized in that a filler piece (44) is arranged in the connecting element (38) on a side facing the wiper arm (10), which filler piece tightly abuts inner walls of the connecting element (38), and wherein a bulkhead wall (60) that runs transverse to a longitudinal axis of the wiper blade (12) is provided on a drive side of the connecting piece (22), which bulkhead wall engages in a slot (58) of the filler piece (44) with little play.

6. Device (20) according to claim 5, characterized in that an adapter (30) is fixed via fastening means (34, 40) in the profile of the connecting element (38) that is open towards the connecting piece (22) and the filler piece (44) is arranged following the adapter (30) and tightly abuts an adjacent face of the adapter (30), wherein the adapter can be pivoted on the connecting piece.

7. Device (20) according to claim 6, characterized in that the face of the adapter (30) that is adjacent to the filler piece (44) engages in an overlapping manner in recesses (50, 52, 54) on an adjacent face (48) of the filler piece (44).

8. Device (20) according to claim 5, characterized in that the filler piece (44) is adjacent with at least one rim (46) to an edge (47) on the open side of the connecting element (38).

9. Device (20) for the articulated connection of a wiper blade (12) to a wiper arm (10) of a windshield wiper, the device comprising a connecting element (38), which can be connected to a connecting piece (22) of the wiper blade (12) and which has a profile that is open towards the connecting piece (22), characterized in that a filler piece (44) is arranged in the connecting element (38) on a side facing the wiper arm (10), which filler piece tightly abuts inner walls of the connecting element (38), and characterized in that an adapter (30) is fixed in the profile of the connecting element (38) that is open towards the connecting piece (22), the adapter being in end-to-end relationship with the filler piece, wherein the adapter can be pivoted on the connecting piece (22), and wherein the adapter (30) is fixed via fastening means (34, 40) in the profile of the connecting element (38) that is open towards the connecting piece (22) and the filler piece (44) is arranged following the adapter (30) and tightly abuts an adjacent face of the adapter (30).

10. Device according to claim 9 wherein the adapter is fixed to the connecting element via fastening means (34, 40).

11. Device according to claim 9 wherein the adapter is fixed against pivotal and translational movement relative to the connecting element via fastening means (34, 40).

12. Device (20) according to claim 9, characterized in that the filler piece (44) is adjacent with at least one rim (46) to an edge (47) on the open side of the connecting element (38).

13. Device (20) according to claim 9, characterized in that the face of the adapter (30) that is adjacent to the filler piece (44) engages in an overlapping manner in recesses (50, 52, 54) on an adjacent face (48) of the filler piece (44).

14. Device (20) according to claim 9, characterized in that a bulkhead wall (60) that runs transverse to a longitudinal axis of the wiper blade (12) is provided on a drive side of the connecting piece (22), which bulkhead wall engages in a slot (58) of the filler piece (44) with little play.
