Abstract

The invention relates to a wiper blade (10) consisting of a rubber profiled element (48) comprising a wiper lip (50) and at least one carrier element (46) that can be connected to a wiper arm (18) by means of a fixing element (14) and a connection element (22). The fixing element (14) comprises a covering cap (16) and the connection element (22) fixed to the wiper arm (18) secures the wiper blade (10) perpendicularly to a pivoting axis (20) by means of a clip (52), on the end (54) thereof at an angle to the wiper blade. According to the invention, the covering cap (16) comprises an opening (34) or recess for the angular end (54) of the clip (52), on the side of the cap opposing the rubber profiled element (48), in the region of the connection element (22), said opening only partially overlapping the covering cap (16) in the mounted position.

Claims

1. Wiper blade (10), which is constructed of a rubber profiled element (48) comprised of a wiper lip (50) and at least one support element (46) that can be connected to a wiper arm (18) by means of a fixing element (14) and a connection element (22), wherein the fixing element (14) has a covering cap (16) and the connection element (22) fastened to the wiper arm (18) secures the wiper blade (10) via a clip (52) transverse to a pivoting axis (20) by means of an end (54) of the clip (52) that is bent towards the wiper blade (10), characterized in that the covering cap (16) features an opening (34) or recess for the bent end (54) of the clip (52) on the side of the cap (16) facing away from the rubber profiled element (48) in the region of the connection element (22), which clip only partially overlaps the covering cap (16) in the mounted position.

2. Wiper blade (10) according to claim 1, characterized in that a covering wall (38) of the covering cap (16) runs beneath the clip (52) inclined towards the inflow direction (42).

3. Wiper blade (10) according to claim 1, characterized in that the covering cap (16) has guide ribs (36) on the opening (34) or the recess, on the one hand, and on an outer side that faces the wiper arm (18), on the other hand.

4. Wiper blade (10) according to claim 1, characterized in that a spoiler (12) is provided and the covering cap (16) blends harmoniously on each of its ends with a connecting profile (30) into the profile of the spoiler (12).

5. Wiper blade (10) according to claim 1, characterized in that the wiper arm comprises a wiper rod (18) with a rectangular cross section, which in a mounted position runs at least partially on the inflow side of the wiper blade (10) and is rotated around its longitudinal axis in such a way that, at least in the region of the wiper blade (10), the wide side of the wiper rod (18) for supporting the spoiler (12) runs inclined to the inflow direction (42) and its end (26) is arranged with the wide side parallel to the guide ribs (36) on the outer side of the covering cap (16).

6. Wiper blade (10) according to claim 1, characterized in that the connection element (22) has a fastening plate (56) running parallel to a wide side of the wiper rod (18), on which fastening plate the clip (52) is formed, wherein the bearing pin (28) has a rivet pin (62) on one end, with which the fastening plate (56) is fastened to the wiper rod (18, 26).

7. Wiper blade (10) according to claim 6, characterized in that the rivet pin (62) is pre-mounted in the fastening plate (56) with a press fit.

8. Wiper blade (10) according to claim 6, characterized in that the connection element (22) has, on its longitudinal sides, bracket-like edges (64) that are bent towards the wiper rod (18), which abut the outer contour of the end (26) of the wiper rod (18) with a press fit in the region of its rounded tips (58).

9. Wiper blade (10) according to claim 8, characterized in that the clearance between the bracket-like edges (64) is less than the width of the end (26) of the wiper rod (18) so that a press fit results when they are joined.

10. Wiper blade (10) according to claim 8, characterized in that the clearance between the bracket-like edges (64) is greater than the width of the end (26) of the wiper rod (18) so that a press fit is produced by crimping the bracket-like edges (64).

11. Wiper blade (10) according to claim 6, characterized in that the end (26) of the wiper rod (18) has a hole (78) offset in the longitudinal direction from the bearing pin (28), in which hole an indentation (80) engages in a mounted state of the connection element (22).

12. Wiper blade (10) according to claim 6, characterized in that the fastening plate (56) overlaps the front side of the end (26) of the wiper rod (18) with a front angle (60).

13. Wiper blade (10) according to claim 6, characterized in that the fastening plate (56) is attached on the outer side of the end (26) of the wiper rod (18) and the clip (52) grips over the end (26) and abuts the rounded tip (58) of the end (26) following the contour.

14. Wiper blade (10) according to claim 6, characterized in that the fastening plate (56) is attached on the inner side of the end (26) of the wiper rod (18) and a covering (70) is provided on the opposite side of the end (26).

15. Wiper blade (10) according to claim 14, characterized in that the front wall (72) of the covering (70) covers the front side of the end (26) and of the connection element (22).

16. Wiper blade (10) according to claim 13, characterized in that the covering (70) clips into a snap-in hole (68) of the end (26) of the wiper rod (18).

17. Wiper blade (10) according to claim 6, characterized in that the fastening plate (56) forms a side wall of an open cross-sectional profile (76) of a connection element (74), which is slid over the end (26) of the wiper rod (18).
