Wiper blade, in particular for a motor vehicle
The invention relates to a wiper blade ( 10 ), in particular for a motor vehicle. Said wiper blade comprises a wiper strip ( 12 ), a supporting element ( 14 ), a liquid channel ( 26 ), and a wind deflector strip ( 18 ). According to the invention, a closure stopper ( 36 ) closes the liquid channel ( 26 ) at at least one channel end ( 34 ) in the region of an end cap ( 22 ) without being in contact with the end cap.
1. A wiper blade ( 10 ) comprising a wiper strip ( 12 ), a supporting element ( 14 ), a liquid channel ( 26 ), a closure plug ( 36 ), an end cap ( 22 ) defining a receiving cavity, and a wind deflector strip ( 18 ), characterized in that the end cap ( 22 ) is assembled on the wind deflector strip ( 18 ), wherein the liquid channel ( 26 ) is disposed within the wind deflector strip ( 18 ) and extends along a longitudinal extent (L) to a channel end ( 34 ), wherein the closure plug ( 36 ) is disposed entirely within the liquid channel ( 26 ) and closes the liquid channel ( 26 ) in a region of the channel end ( 34 ), wherein the channel end ( 34 ) is disposed within the receiving cavity of the end cap ( 22 ), wherein the channel end ( 34 ) is not connected to or in contact with any component of the end cap ( 22 ), such that the channel end ( 34 ) is open to the receiving cavity within the end cap ( 22 ), and wherein the closure plug ( 36 ) is not connected to or in contact with any component of the end cap ( 22 ), and is spaced away from the channel end ( 34 ).
2. The wiper blade ( 10 ) as claimed in claim 1 , wherein the end cap ( 22 ) is fastened to the supporting element ( 14 ) and seals the supporting element along a longitudinal extent (L).
3. The wiper blade ( 10 ) as claimed in claim 1 , wherein the closure plug ( 36 ) is ball-shaped.
4. The wiper blade ( 10 ) as claimed in claim 3 , wherein the closure plug ( 36 ) is a steel ball.
5. The wiper blade ( 10 ) as claimed in claim 1 , wherein a spacing between a plug end ( 38 ) of the closure plug ( 36 ) and the channel end ( 34 ) of the liquid channel ( 26 ) in the longitudinal extent (L) is at least 1 millimeter.
6. The wiper blade ( 10 ) as claimed in claim 5 , wherein the spacing is at least 5 millimeters.
7. The wiper blade ( 10 ) as claimed in claim 1 , wherein a spacing between a plug end ( 38 ) of the closure plug ( 36 ) and the end cap ( 22 ) is at least 1 millimeter.
8. The wiper blade ( 10 ) as claimed in claim 7 , wherein the spacing is at least 5 millimeters.
9. The wiper blade ( 10 ) as claimed in claim 1 , wherein the liquid channel ( 26 ) is provided for active wetting.
