Abstract

The invention relates to a wiper blade adapter unit for connecting a wiper blade ( 10 ) to a wiper arm adapter ( 12 ), comprising a main part ( 16 ) which receives an end ( 14 ) of the wiper arm adapter ( 12 ) in particular and which has a plateau ( 20 ) on the main part lower face ( 18 ). At least one region ( 22, 24, 26 ) is provided on the main part ( 16 ), said region being designed in a flexible manner for the purpose of a shape and/or tolerance compensation. The region ( 22 ) that is flexible for the purpose of a shape and/or tolerance compensation is arranged within the plateau ( 20 ).

First claim

What is claimed is:

2. The wiper blade adapter unit according to claim 1 , characterized in that the region ( 22 ) embodied as a resilient lug comprises at least one abutment surface ( 28 ) which forms a stop for the wiper arm adapter ( 12 ).

3. The wiper blade adapter unit according to claim 2 , characterized in that the main part ( 16 ) has an upper abutment surface ( 32 ) on the upper face ( 30 ), the upper abutment surface having therein a pocket ( 34 ) which extends at least substantially in a wiping direction.

4. The wiper blade adapter according to claim 3 , characterized in that the main part ( 16 ) comprises two side walls ( 36 , 38 ) which each have at least four slots ( 40 ) in a region of the plateau ( 20 ).

5. The wiper blade adapter unit according to claim 4 , characterized in that the main part ( 16 ) comprises at least one side wall ( 36 , 38 ) which has at least one open slot ( 40 ) in a region of the plateau ( 20 ), said slot being at least substantially delimited in a main extension thereof from a closed side thereof up to an open side thereof by a single, at least substantially rectilinear contour line ( 96 ).

6. The wiper blade adapter unit according to claim 1 , characterized in that the main part ( 16 ) has an upper abutment surface ( 32 ) on the upper face ( 30 ), the upper abutment surface having therein a pocket ( 34 ) which extends at least substantially in a wiping direction.

7. The wiper blade adapter according to claim 1 , characterized in that the main part ( 16 ) comprises two side walls ( 36 , 38 ) which each have at least four slots ( 40 ) in a region of the plateau ( 20 ).

8. The wiper blade adapter unit according to claim 1 , characterized in that the main part ( 16 ) comprises at least one side wall ( 36 , 38 ) which has at least one open slot ( 40 ) in a region of the plateau ( 20 ), said slot being at least substantially delimited in a main extension thereof from a closed side thereof up to an open side thereof by a single, at least substantially rectilinear contour line ( 96 ).

9. The wiper blade adapter unit according to claim 1 , wherein the main part ( 16 ) includes two side walls ( 36 , 38 ), wherein the lower abutment surface ( 58 ) extends between the two side walls ( 36 , 38 ), and wherein the flexible resilient lug is closer to one of the two side walls than the other side wall.

10. The wiper blade adapter unit according to claim 9 , wherein the flexible resilient lug includes at least one side abutment surface ( 28 ), and wherein the at least one side abutment surface ( 28 ) faces toward one of the two side walls ( 36 , 38 ).

11. The wiper blade adapter unit according to claim 9 , wherein the region ( 22 ) is a first region and the resilient flexible lug is a first resilient flexible lug, and wherein the at least one region ( 22 , 24 , 26 ) includes a second region ( 24 ) that includes a second resilient flexible lug that is closer to one of the two side walls than the other side wall.

12. The wiper blade adapter unit according to claim 11 , wherein the at least one side abutment surface ( 28 ) is a first side abutment surface, wherein the second flexible resilient lug includes a second side abutment surface ( 102 ), and wherein the second side abutment surface ( 102 ) also faces one of the two side walls ( 36 , 38 ).

13. The wiper blade adapter unit according to claim 1 , wherein the lower abutment surface ( 58 ) defines an L-shaped groove ( 86 ) that extends at least partially around the resilient flexible lug.

14. The wiper blade adapter unit according to claim 1 , wherein the at least one region ( 22 , 24 , 26 ) includes three flexible resilient lugs.

15. The wiper blade adapter unit according to claim 1 , wherein a side wall ( 36 ) extends from the lower abutment surface ( 58 ), and wherein the flexible resilient lug includes at least one side abutment surface ( 28 ) which faces toward the side wall ( 36 ), such that when the wiper arm adapter ( 12 ) has a first width, the wiper arm adapter ( 12 ) is configured to press the flexible resilient lug in a direction toward the lower abutment surface ( 58 ), and when the wiper arm adapter ( 12 ) has a second, smaller width, the wiper arm adapter ( 12 ) is configured to be disposed between the side abutment surface ( 28 ) and the side wall ( 36 ), without pressing the flexible resilient lug in the direction toward the lower abutment surface ( 58 ).

16. A wiper blade adapter unit for connecting a wiper blade ( 10 ) to a wiper arm adapter ( 12 ), comprising a main part ( 16 ) which receives an end ( 14 ) of the wiper arm adapter ( 12 ) and which has a plateau ( 20 ) on a main part lower face ( 18 ), wherein at least one region ( 22 , 24 , 26 ) is provided on the main part ( 16 ), which at least one region is designed in a flexible manner for the purpose of at least one of shape compensation and tolerance compensation, characterized in that the at least one region ( 22 , 24 , 26 ) includes a region ( 22 ) that is arranged within the plateau ( 20 ), wherein the region ( 22 ) includes a flexible resilient lug, wherein the main part lower face ( 18 ) includes a lower abutment surface ( 58 ) configured to contact the wiper arm adapter ( 12 ), wherein the flexible resilient lug is movable relative to the lower abutment surface ( 58 ), wherein the main part ( 16 ) includes two side walls ( 36 , 38 ), wherein the lower abutment surface ( 58 ) extends between the two side walls ( 36 , 38 ), wherein the flexible resilient lug is closer to one of the two side walls than the other side wall, wherein the flexible resilient lug includes at least one side abutment surface ( 28 ), and wherein the at least one side abutment surface ( 28 ) faces toward one of the two side walls ( 36 , 38 ).

17. The wiper blade adapter unit according to claim 16 , characterized in that the region ( 22 ) embodied as a resilient lug comprises at least one abutment surface ( 28 ) which forms a stop for the wiper arm adapter ( 12 ).
