Abstract

The invention is based on a wiper blade (10) comprising a wiper strip (12), in the lateral longitudinal grooves (20) of which two parallel spring rails (24) are inserted as a supporting element in the head strip (16), wherein a spoiler (30) and end caps (32, 48) are provided on the rails. The end caps (32, 48) each connect with a flow profile (34) to the spoiler (30) and extend at the front sides facing the ends of the wiper blade (10) toward a wiper lip (14) over the spring rails (24). It is proposed that at least one end cap (32, 48) comprises a closeable assembly opening (38) in the region overlapping the spring rails (24) and the head strip (16).

Claims

1. A wiper blade (10) with a wiper strip (12) which in lateral longitudinal grooves (20) in its head strip (16), has, as supporting element, two spring rails (24) which run in parallel and on which a spoiler (30) and end caps (32, 48) are provided, wherein the end caps (32, 48) are each connected by a flow profile (34) to the spoiler (30) and, on their end sides facing the ends of the wiper blade (10), reach over the spring rails (24) toward a wiper lip (14), characterized in that at least one end cap (32, 48) has a closeable assembly opening (38) in the region which overlaps the spring rails (24) and the head strip (16), characterized in that the assembly opening (38) is closed by a cross bar (40) which slides linearly and transversely with respect to a longitudinal direction of the wiper blade (10) to open and close the closeable assembly opening (38).

2. The wiper blade (10) as claimed in claim 1, characterized in that the cross bar (40) is guided on the end cap (32, 48) by means of a guide profile (42).

3. The wiper blade (10) as claimed in claim 1, characterized in that the cross bar (40) has an outwardly facing gripping strip (44).

4. The wiper blade (10) as claimed in claim 1, characterized in that the cross bar (40) is secured in the closed position by a catch (46).

5. The wiper blade (10) as claimed in claim 1, characterized in that the spring rails (24) are connected to each other at their ends by a respective transverse clip (26) to which a retaining spring (56) is fastened, said retaining spring facing the center of the wiper blade (10) and pressing against a back strip (28) of the head strip (16).

6. The wiper blade (10) as claimed in claim 1, characterized in that the end cap (32) is fixedly connected to the spoiler (30).

7. The wiper blade (10) as claimed in claim 1, characterized in that the end cap (48) can be released and, in a shallow part (36) of the flow profile (34), has a spring tongue (50) which faces in the longitudinal direction of the wiper blade (10), can be actuated from outside and latches by means of a latching lug (52) to a transverse clip (26) which connects the two spring rails (24) to each other.

8. The wiper blade (10) as claimed in claim 7, characterized in that the spring tongue (50) has an operating element (54) on its side facing outward.

9. The wiper blade (10) as claimed in claim 1, characterized in that the wiper strip (12) is removable from the wiper blade (10) through the assembly opening (38).

10. The wiper blade (10) as claimed in claim 1, characterized in that the spring rails (24) are removable from the wiper blade (10) through the assembly opening (38).

11. A wiper blade (10) with a wiper strip (12), at least one supporting element for holding the wiper strip, and one or more end caps (32, 48) which are supported at retaining means on the respective ends of the supporting element, wherein at least one end cap (32, 48) prevents the wiper strip from being intentionally or unintentionally pulled out of or from the supporting element, characterized in that the at least one end cap (32, 48) has a cross bar (40) for opening and closing an assembly opening (38), and characterized in that the cross bar (40) slides linearly and transversely with respect to the longitudinal direction of the wiper blade (10) to open and close the assembly opening (38).

12. The wiper blade (10) as claimed in claim 11, characterized in that the cross bar (40) is guided on the end cap (32, 48) by means of a guide profile (42).

13. The wiper blade (10) as claimed in claim 11, characterized in that the cross bar (40) has an outwardly facing gripping strip (44).

14. The wiper blade (10) as claimed in claim 13, characterized in that the cross bar (40) is secured in the closed position by a catch (46).

15. The wiper blade (10) as claimed in claim 11, characterized in that the cross bar (40) is secured in the closed position by a catch (46).

16. The wiper blade (10) as claimed in claim 11, characterized in that the wiper strip (12) has, in lateral longitudinal grooves (20) in its head strip (16), as the supporting element, two spring rails (24) which run in parallel and on which a spoiler (30) and end caps (32, 48) are provided, wherein the end caps (32, 48) are each connected by a flow profile (34) to the spoiler (30) and, on their end sides facing the ends of the wiper blade (10), reach over the spring rails (24) toward a wiper lip (14), wherein the at least one end cap (32, 48) has the assembly opening (38) in the region which overlaps the spring rails (24) and the head strip (16).

17. The wiper blade (10) as claimed in claim 16, characterized in that the spring rails (24) are connected to each other at their ends by a respective transverse clip (26) to which a retaining spring (56) is fastened, said retaining spring facing the center of the wiper blade (10) and pressing against a back strip (28) of the head strip (16).

18. The wiper blade (10) as claimed in claim 16, characterized in that the spring rails (24) are removable from the wiper blade (10) through the assembly opening (38).

19. The wiper blade (10) as claimed in claim 12, characterized in that the wiper strip (12) is removable from the wiper blade (10) through the assembly opening (38).

20. A wiper blade (10) with a wiper strip (12) which in lateral longitudinal grooves (20) in its head strip (16), has, as supporting element, two spring rails (24) which run in parallel and on which a spoiler (30) and end caps (32, 48) are provided, wherein the end caps (32, 48) are each connected by a flow profile (34) to the spoiler (30) and, on their end sides facing the ends of the wiper blade (10), reach over the spring rails (24) toward a wiper lip (14), characterized in that at least one end cap (32, 48) has a closeable assembly opening (38) in the region which overlaps the spring rails (24) and the head strip (16), characterized in that the spring rails (24) are connected to each other at their ends by a respective transverse clip (26) to which a retaining spring (56) is fastened, said retaining spring facing the center of the wiper blade (10) and pressing against a back strip (28) of the head strip (16).
