Abstract

A wiper blade (18) with a connecting device (84) to connect a wiper arm (10), which connecting device features a pivoted adapter (66) equipped with holding surfaces (70, 72) for the wiper arm (10) and an openable and closeable protective cap (26), which in its closed position can fix the wiper arm (10) with limiting surfaces (64) arranged on an inner side by means of the holding surfaces (70, 72). The protective cap (26) has an openable and closeable cover (50) with an opening in its covering wall through which the wiper arm (10) can be connected to the adapter (66).

Claims

1. Wiper blade (18) with a connecting device (84) to connect a wiper arm (10), which connecting device features a pivoted adapter (66) equipped with holding surfaces (70, 72) for the wiper arm (10) and an openable and closeable protective cap (26), which in its closed position can fix the wiper arm (10) with limiting surfaces (64) arranged on an inner side by means of the holding surfaces (70, 72), characterized in that the protective cap (26) has an openable and closeable cover (50), and the cover (50) includes a covering wall defining an opening (44) through which the wiper arm (10) can be connected to the adapter (66).

2. Wiper blade (18) according to claim 1, characterized in that the protective cap (26) includes the connecting device (84) and is clipped via this, wherein the cover (50) features the limiting surface (64) on its inner side, through which, in a closed position of the cover (50), a hook-shaped end (12) of the wiper arm (10) is fixed on the adapter (66) in its assembled position.

3. Wiper blade (18) according to claim 1, characterized in that the cover (50) is pivoted on the protective cap (26) in the area of a rear wall (30) of the protective cap (26), which points towards the drive-side end of the wiper blade (18).

4. Wiper blade (18) according to claim 3, characterized in that either the cover (50) or the protective cap (26) features at least one open hub (52) in the area of the rear side (30), which cooperates with a cylindrical bearing element (46) that is flattened on the circumference in such a way that the open hub (52) can be pushed over the flattenings (48) of the bearing element (46) in the completely opened position of the cover (50), while the hub (52) is held on the bearing element (46) in a half-opened or closed position of the cover (50).

5. Wiper blade (18) according to claim 3, characterized in that the cover (50) has at least one locking pin (62) in the area of its front wall (58), which engages in a locking opening (40) on the protective cap (26) in the closed position of the cover (50).

6. Wiper blade (18) according to claim 1, characterized in that a limiting bridge (64) projecting on the inner side of the cover (50) in the area of a front wall (58) forms the limiting surface.

7. Wiper blade (18) according to claim 2, characterized in that the cover (50) is pivoted on the protective cap (26) in the area of a rear wall (30) of the protective cap (26), which points towards the drive-side end of the wiper blade (18).

8. Wiper blade (18) according to claim 4, characterized in that the cover (50) has at least one locking pin (62) in the area of its front wall (58), which engages in a locking opening (40) on the protective cap (26) in the closed position of the cover (50).

9. Wiper blade (18) according to claim 2, characterized in that a limiting bridge (64) projecting on the inner side of the cover (50) in the area of a front wall (58) forms the limiting surface.

10. Wiper blade (18) according to claim 3, characterized in that a limiting bridge (64) projecting on the inner side of the cover (50) in the area of a front wall (58) forms the limiting surface.

11. Wiper blade (18) according to claim 4, characterized in that a limiting bridge (64) projecting on the inner side of the cover (50) in the area of a front wall (58) forms the limiting surface.

12. Wiper blade (18) according to claim 5, characterized in that a limiting bridge (64) projecting on the inner side of the cover (50) in the area of a front wall (58) forms the limiting surface.

13. Wiper blade (18) according to claim 7, characterized in that the cover (50) has at least one locking pin (62) in the area of its front wall (58), which engages in a locking opening (40) on the protective cap (26) in the closed position of the cover (50).

14. Wiper blade (18) according to claim 7, characterized in that either the cover (50) or the protective cap (26) features at least one open hub (52) in the area of the rear side (30), which cooperates with a cylindrical bearing element (46) that is flattened on the circumference in such a way that the open hub (52) can be pushed over the flattenings (48) of the bearing element (46) in the completely opened position of the cover (50), while the hub (52) is held on the bearing element (46) in a half-opened or closed position of the cover (50).

15. Wiper blade (18) according to claim 14, characterized in that the cover (50) has at least one locking pin (62) in the area of its front wall (58), which engages in a locking opening (40) on the protective cap (26) in the closed position of the cover (50).

16. Wiper blade (18) according to claim 15, characterized in that a limiting bridge (64) projecting on the inner side of the cover (50) in the area of a front wall (58) forms the limiting surface.
