Abstract

A wiper blade (10) comprising a rubber elastic wiper strip (12) into whose lateral longitudinal grooves resilient rails (18, 20) are inserted as support elements and laterally protrude from the longitudinal grooves, wherein the resilient rails (18, 20) are held together at their ends and are fixed relative to the wiper strip (12) in the longitudinal direction and support a terminal cap (24). It is proposed that the terminal caps (24) have detachable fixing means (34) that engage in a top strip (16) of the wiper strip (12), wherein the axial movability of the resilient rails (18, 20) relative to the wiper strip (24) is limited by the terminal caps.

Claims

1. Wiper blade (10) comprising a rubber elastic wiper strip (12) into whose lateral longitudinal grooves resilient rails (18, 20) are inserted as support elements, wherein the resilient rails (18, 20) have ends, are held together at the ends and are fixed relative to the wiper strip (12) in a longitudinal direction and support a terminal cap (24), wherein the terminal cap (24) has detachable fixing means (34) that engage in a top strip (16) of the wiper strip (12), wherein axial movability of the resilient rails (18, 20) relative to the wiper strip (24) is limited by the terminal cap, wherein the detachable fixing means (34) includes, on the terminal cap, a flexible tongue (30, 44) that runs essentially parallel to an upper side of the top strip (16) and said tongue has a locking nose (34) on its underside that engages in the top strip (16), and characterized in that the terminal cap (24) has a recess (28) pointing to an outer front side of the terminal cap, into which a bar (38, 46) is guided, which in a locked position presses the flexible tongue (30, 44) with its locking nose (34) against the top strip (16).

2. Wiper blade (10) according to claim 1, characterized in that the flexible tongue (30, 44) has a wedge-shaped projection (32) on its side facing the bar (38, 46), which diminishes in terms of its height in an opening direction of the bar (38, 46).

3. Wiper blade (10) according to claim 2, characterized in that the locking nose (34) increases in height in a wedge-shaped manner in the opening direction of the bar (38, 46).

4. Wiper blade (10) according to claim 2, characterized in that the bar (38, 46) is connected to the terminal cap (24) before final assembly via at least one predetermined breaking point (42).

5. Wiper blade (10) according to claim 2, characterized in that the flexible tongue (30) has snap-in pegs (36) on the side facing the resilient rails (18, 20), which engage in snap-in holes (22) of the resilient rails (18, 20).

6. Wiper blade (10) according to claim 2, characterized in that the locking nose (34) increases in height in a wedge-shaped manner in an opening direction of the bar (38, 46).

7. Wiper blade (10) according to claim 1, characterized in that the bar (38, 46) is connected to the terminal cap (24) before final assembly via at least one predetermined breaking point (42).

8. Wiper blade (10) according to claim 7, characterized in that the flexible tongue (30) has snap-in pegs (36) on the side facing the resilient rails (18, 20), which engage in snap-in holes (22) of the resilient rails (18, 20).

9. Wiper blade (10) according to claim 7, characterized in that the bar (46) has lateral gripping cavities (48).

10. Wiper blade (10) according to claim 1, characterized in that the bar (46) has lateral gripping cavities (48).

11. Wiper blade (10) according to claim 1, characterized in that the locking nose (34) increases in height in a wedge-shaped manner in the opening direction of the bar (38, 46).

12. Wiper blade (10) according to claim 1, characterized in that the flexible tongue (30) has snap-in pegs (36) on the side facing the resilient rails (18, 20), which engage in snap-in holes (22) of the resilient rails (18, 20).

13. Wiper blade (10) according to claim 1, characterized in that the bar (46) has lateral gripping cavities (48).

14. Wiper blade (10) comprising a rubber elastic wiper strip (12) into whose lateral longitudinal grooves resilient rails (18, 20) are inserted as support elements, wherein the resilient rails (18, 20) have ends, are held together at the ends and are fixed relative to the wiper strip (12) in a longitudinal direction and support a terminal cap (24), wherein the terminal cap (24) has detachable fixing means (34) that engage in a top strip (16) of the wiper strip (12), wherein axial movability of the resilient rails (18, 20) relative to the wiper strip (24) is limited by the terminal cap, wherein the detachable fixing means (34) includes, on the terminal cap, a flexible tongue (30, 44) that runs essentially parallel to an upper side of the top strip (16) and said tongue has a locking nose (34) on its underside that engages in the top strip (16), characterized in that the terminal cap (24) has a recess (28) pointing to an outer front side of the terminal cap, into which a bar (38, 46) is guided, which in a locked position presses the flexible tongue (30, 44) with its locking nose (34) against the top strip (16), and characterized in that the locking nose (34) increases in height in a wedge-shaped manner in an opening direction of the bar (38, 46).

15. Wiper blade (10) according to claim 14, characterized in that the bar (38, 46) is connected to the terminal cap (24) before final assembly via at least one predetermined breaking point (42).

16. Wiper blade (10) according to claim 14, characterized in that the flexible tongue (30) has snap-in pegs (36) on the side facing the resilient rails (18, 20), which engage in snap-in holes (22) of the resilient rails (18, 20).
