Abstract

The invention relates to a wiper blade latching device, for coupling a wiper blade (10) to a wiper arm (12), having at least one wiper unit (14) which has at least one latching means (16, 18), which can be deflected counter to a tensioning force, and at least one guide means (20, 22).

It is proposed that the latching means (16, 18) is at least partially decoupled from the guide means (20, 22).

Claims

1. Wiper blade latching device, for coupling a wiper blade (10) to a wiper arm (12), the device having at least one wiper unit (14) which has at least one latching means (16, 18), which can be deflected counter to a tensioning force, and at least one guide means (20, 22), characterized in that the latching means (16, 18) is at least partially decoupled from the guide means (20, 22).

2. Wiper blade latching device according to claim 1, characterized in that the guide means (20, 22) is arranged in front of the latching means (16, 18) in an insertion direction (30) of a fastening means (36) which, during the assembly of the wiper blade (10), corresponds with the latching means (16, 18).

3. Wiper blade latching device according to claim 1, characterized in that a recess (24, 26) which forms a free movement space of the latching means (16, 18) is arranged between the latching means (16, 18) and the guide means (20, 22).

4. Wiper blade latching device according to claim 3, characterized in that the recess (24, 26) which forms the free movement space is formed in the manner of a slot.

5. Wiper blade latching device according to claim 1, characterized in that the wiper unit (14) has a recess (28) which forms an insertion region.

6. Wiper blade latching device according to claim 5, characterized in that the recess (28) which forms the insertion region is formed so as to taper in an insertion direction (30) of a fastening means (36) which, during the assembly of the wiper blade (10), corresponds with the latching means (16, 18).

7. Wiper blade latching device according to claim 5, characterized in that the recess (28) which forms the insertion region is delimited by the latching means (16, 18) and by the guide means (20, 22).

8. Wiper blade latching device according to claim 3, characterized in that the recess (24, 26) which forms the free movement space opens out into the recess (28) which forms the insertion region.

9. Wiper blade latching device according to claim 1, characterized in that at least the latching means (16, 18) is formed at least partially from plastic.

10. Wiper blade latching device according to claim 1, characterized in that the latching means (16, 18) and the guide means (20, 22) are formed in one piece.

11. Wiper blade latching device according to claim 1, characterized in that the wiper unit (14) forms a part of the wiper arm (12).

12. Wiper blade latching device according to claim 6, characterized in that the recess (28) which forms the insertion region is delimited by the latching means (16, 18) and by the guide means (20, 22).

13. Wiper blade latching device according to claim 12, characterized in that the recess (24, 26) which forms the free movement space opens out into the recess (28) which forms the insertion region.

14. Wiper blade latching device according to claim 7, characterized in that the recess (24, 26) which forms the free movement space opens out into the recess (28) which forms the insertion region.

15. Wiper arm having a wiper blade latching device, for coupling a wiper blade (10) to the wiper arm, the device having at least one wiper unit (14) which has at least one latching means (16, 18), which can be deflected counter to a tensioning force, and at least one guide means (20, 22), characterized in that the latching means (16, 18) is at least partially decoupled from the guide means (20, 22).

16. Wiper arm according to claim 15, characterized in that the guide means (20, 22) is arranged in front of the latching means (16, 18) in an insertion direction (30) of a fastening means (36) which, during the assembly of the wiper blade (10), corresponds with the latching means (16, 18).

17. Wiper arm according to claim 15, characterized in that a recess (24, 26) which forms a free movement space of the latching means (16, 18) is arranged between the latching means (16, 18) and the guide means (20, 22).

18. Wiper arm device according to claim 17, characterized in that the recess (24, 26) which forms the free movement space is formed in the manner of a slot.

19. Wiper arm according to claim 15, characterized in that the wiper unit (14) has a recess (28) which forms an insertion region.

20. Wiper arm according to claim 19, characterized in that the recess (28) which forms the insertion region is formed so as to taper in an insertion direction (30) of a fastening means (36) which, during the assembly of the wiper blade (10), corresponds with the latching means (16, 18).
