The invention relates to a wiper blade for a window wiper, in particular a window wiper for a motor vehicle, comprising a wiper rubber (1) made from an elastomer material with a base section (3) and a lip section (5), wherein the elastomer material at least partially surrounds a fabric insert (13).
The invention relates to a wiper blade for a window wiper, in particular a window wiper for a motor vehicle, comprising a wiper rubber (1) made from an elastomer material with a base section (3) and a lip section (5), wherein the elastomer material at least partially surrounds a fabric insert (13). The base section (3) and the lip section (5) are connected to each other by the fabric insert (13), wherein the fabric insert (13) serves as a joint (7), and/or a part (17) of the fabric insert (13) protrudes out of the base section (3) on the side facing away from the lip section (5). Furthermore, the invention relates to a method for producing a wiper blade, in which a fabric strip is guided through an extruder die in order to form a fabric insert (13), the fabric strip is surrounded by an elastomer material in order to produce an extruded profile, and the extruded profile is cut into individual wiper rubbers (1).

1. A wiper blade for a window wiper, comprising a wiping rubber (1) of an elastomer material with a base portion (3) and a lip portion (5), wherein the elastomer material partially encloses a fabric insert (13), characterized in that the base portion (3) and the lip portion (5) are connected to each
1. A wiper blade for a window wiper, comprising a wiping rubber (1) of an elastomer material with a base portion (3) and a lip portion (5), wherein the elastomer material partially encloses a fabric insert (13), characterized in that the base portion (3) and the lip portion (5) are connected to each other by the fabric insert (13), wherein part (17) of the fabric insert (13) protrudes from the base portion (3) free from any material on a side of the base portion (3) facing away from the lip portion (5), wherein the lip portion (5) and the base portion (3) of the wiping rubber (1) are produced from different material. 2. The wiper blade as claimed in claim 1, characterized in that the part (17) of the fabric insert (13) that is protruding from the base portion (3) has a thickening (19). 3. The wiper blade as claimed in claim 2, characterized in that the thickening (19) is formed at an end of the part (17) of the fabric insert (13) that is protruding from the base portion (3). 4. The wiper blade as claimed in claim 1, characterized in that the part (17) of the fabric insert (13) that is protruding from the base portion (13) forms a sleeve (21) in which a spring element can be fitted. 5. The wiper blade as claimed in claim 1, characterized in that the fabric insert (13) contains aramid fibers. 6. A method for producing a wiper blade as claimed in claim 1, comprising the following steps: (a) guiding a fabric strip through a die of an extruder to form a fabric insert (13),(b) enclosing the fabric strip in an elastomer material to produce an extruded profile,(c) cutting the extruded profile into individual wiping rubbers (1). 7. The method as claimed in claim 6, characterized in that the extruded profile is vulcanized before the cutting in step (c). 8. The method as claimed in claim 6, characterized in that the elastomer material is selected from the group comprising natural rubber, chloroprene rubber, ethylene-propylene-diene terpolymers and mixtures of two or more thereof. 9. The wiper blade as claimed in claim 1, characterized in that the base portion (3) and the lip portion (5) are integral. 10. A wiper blade for a window wiper, comprising a wiping rubber (1) of an elastomer material with a base portion (3) and a lip portion (5), wherein the elastomer material partially encloses a fabric insert (13), characterized in that the base portion (3) and the lip portion (5) are connected to each other only by the fabric insert (13), wherein only the fabric insert (13) is a joint (7) between the base portion (3) and the lip portion (5), and wherein part (17) of the fabric insert (13) protrudes from the base portion (3) free from any material on a side of the base portion (3) facing away from the lip portion (5). 11. The wiper blade as claimed in claim 10, characterized in that the fabric insert (13) contains aramid fibres. 12. The wiper blade as claimed in claim 10, characterized in that the lip portion (5) and the base portion (3) of the wiping rubber (1) are produced from different material. 13. The wiper blade as claimed in claim 10, characterized in that the part (17) of the fabric insert (13) that is protruding from the base portion (3) has a thickening (19). 14. The wiper blade as claimed in claim 13, characterized in that the thickening (19) is formed at an end of the part (17) of the fabric insert (13) that is protruding from the base portion (3). 15. The wiper blade as claimed in claim 10, characterized in that the part (17) of the fabric insert (13) that is protruding from the base portion (13) forms a sleeve (21) in which a spring element can be fitted. 16. A method for producing a wiper blade as claimed in claim 10, comprising the following steps: (a) guiding a fabric strip through a die of an extruder to form a fabric insert (13),(b) enclosing the fabric strip in an elastomer material to produce an extruded profile,(c) cutting the extruded profile into individual wiping rubbers (1). 17. The method as claimed in claim 16, characterized in that the extruded profile is vulcanized before the cutting in step (c). 18. The method as claimed in claim 16, characterized in that the elastomer material is selected from the group comprising natural rubber, chloroprene rubber, ethylene-propylene-diene terpolymers and mixtures of two or more thereof. 19. The wiper blade as claimed in claim 10, characterized in that the fabric insert (13) at the joint (7) is uncovered by the elastomer material. 20. A wiper blade for a window wiper, comprising a wiping rubber (1) of an elastomer material with a base portion (3) and a lip portion (5), wherein the elastomer material partially encloses a fabric insert (13), characterized in that the base portion (3) and the lip portion (5) are connected to each other by the fabric insert (13), wherein part (17) of the fabric insert (13) protrudes from the base portion (3) free from any material on a side of the base portion (3) facing away from the lip portion (5), wherein the part (17) of the fabric insert (13) that is protruding from the base portion (3) has a thickening (19).
