Abstract

The invention is based on a wiper blade (10) having a wiping strip (12) and two spring rails (22) which serve as a supporting element and are inserted into lateral longitudinal grooves (20) in the wiping blade (12) and are permanently connected to one another at their ends by a bridge (24), wherein a wiper blade termination (25) is provided at the end of the wiper blade (10), the base element (26) of which wiper blade termination (25) is guided on the spring rails (22), is secured relative to the spring rails (22) and has a pointed-tip holder (40), the tip of which (66) engages in the wiping strip (12) in the mounted state and secures the wiping strip (12) relative to the spring rails (22). It is proposed that the base element (26) have, in its cover wall (34), a detent opening (28) which locks with the bridge (24) during installation and also a lateral opening (30) into which the pointed-tip holder (40) can be inserted and locked in the end position on the base element (26), wherein the tip (66) penetrates the wiping strip (12) laterally.

Claims

1. A wiper blade (10) having a longitudinal direction and comprising a wiping strip (12) and two spring rails (22) which extend in the longitudinal direction and serve as a supporting element, wherein the spring rails are coplanar and define a plane, have ends, are inserted into lateral longitudinal grooves (20) in the wiping strip (12) and are permanently connected to one another at their ends by a bridge (24), wherein a wiper blade termination (25) is provided at an end of the wiper blade (10), a base element (26) of which wiper blade termination is guided on the spring rails (22), and is secured relative to the spring rails (22) and has a pointed-tip holder (40), a tip (66) of which engages in the wiping strip (12) in a mounted state and secures the wiping strip (12) relative to the spring rails (22), characterized in that the base element (26) includes a cover wall (34) having therein a detent opening (28) which locks with the bridge (24) during installation, and the base element also has a lateral opening (30) into which the pointed-tip holder (40) is removably inserted, the pointed-tip holder being inserted into the lateral opening in a direction perpendicular to the longitudinal direction and parallel to the plane defined by the spring rails, and being inserted such that the pointed-tip holder locks in an end position on the base element (26), wherein the tip (66) penetrates the wiping strip (12) laterally.

2. The wiper blade (10) as claimed in claim 1, characterized in that the pointed-tip holder (40) has a guide block (46) with lateral guide grooves (48) which match guide webs (50) on the edge of the lateral opening (30).

3. The wiper blade (10) as claimed in claim 2, characterized in that a detent (42) is integrally formed on the guide block (46) in an installation direction, said detent locking in a fitted state with a detent edge (44) in a detent notch (38) on an inner side of the cover wall (34).

4. The wiper blade (10) as claimed in claim 2, characterized in that a push-in compartment for a pointed-tip plate (60), a tip (66) of which faces the wiping strip (12), is located on an inner side of the guide block (46) between two guide grooves (58).

5. The wiper blade (10) as claimed in claim 4, characterized in that a base (64) of the pointed-tip plate (60) has a detent element (70) which locks with a corresponding detent element (84) on the pointed-tip holder (40).

6. The wiper blade (10) as claimed in claim 2, characterized in that a press button (54) for releasing the detent (42) is arranged on the guide block (46).

7. The wiper blade (10) as claimed in claim 6, characterized in that a covering cap (74) covers the base element (26) and the pointed-tip holder (40), said covering cap being guided with guide profiles (78) on the base element (26) and having a closed end wall (86) at the end.

8. The wiper blade (10) as claimed in claim 7, characterized in that an approach flow side of the covering cap (74) has a wind deflecting profile (76) and an open end side of said covering cap has a connection profile (88) for connection to a spoiler.

9. The wiper blade (10) as claimed in claim 7, characterized in that the press button (54) is arranged in a region of the maximum elevation of the wind deflecting profile (76) and is matched to an inner contour of the covering cap (74).

10. The wiper blade (10) as claimed in claim 7, characterized in that detent elements (82) which interact with detent elements (84) on the base element (26) are provided on lower limbs (80) of the guide profiles (78).

11. The wiper blade (10) as claimed in claim 1, characterized in that the lateral opening is offset from the detent opening in the longitudinal direction.

12. A wiper blade (10) having a wiping strip (12) and two spring rails (22) which serve as a supporting element, wherein the spring rails have ends, are inserted into lateral longitudinal grooves (20) in the wiping strip (12) and are permanently connected to one another at their ends by a bridge (24), wherein a wiper blade termination (25) is provided at an end of the wiper blade (10), a base element (26) of which wiper blade termination is guided on the spring rails (22), and is secured relative to the spring rails (22) and has a pointed-tip holder (40), a tip (66) of which engages in the wiping strip (12) in a mounted state and secures the wiping strip (12) relative to the spring rails (22), characterized in that the base element (26) includes a cover wall (34) having therein a detent opening (28) which locks with the bridge (24) during installation, and the base element also has a lateral opening (30) into which the pointed-tip holder (40) can be inserted and locks in an end position on the base element (26), wherein the tip (66) penetrates the wiping strip (12) laterally, and characterized in that the pointed-tip holder (40) has a guide block (46) with lateral guide grooves (48) which match guide webs (50) on the edge of the lateral opening (30).
