Abstract

A connecting piece for connecting a wiper arm to a wiper blade is proposed, which includes yielding regions, so that wiper arms of the most various sizes can be received.

Claims

1. A connecting piece (10) for connecting a wiper blade (11a) to a wiper arm (11), having a body that receives an end of the wiper arm (11), and having means for receiving and bracing the wiper blade, characterized in that on the body or on the means for receiving and bracing the wiper blade, regions (38, 41, 49) are provided, which are formed in yielding fashion for dimensional or tolerance compensation, wherein at least one of said yielding regions (38, 41, 49) is a resilient tab (38), said resilient tab (38) having at least two faces (40a, 13), wherein said at least two faces form stops for differently sized wiper arm ends (11) and wherein said at least two faces each can be transposed upon installation.

2. The connecting piece of claim 1, characterized in that the resilient tab (38) in a position folded out is braced by at least one stabilizing element (58).

3. The connecting piece of claim 1 characterized in that at least one resilient tab is embodied as a curved portion.

4. The connecting piece of claim 1, characterized in that at least one region (49) is embodied as a yielding plateau (53).

5. The connecting piece of claim 1, characterized in that the means for receiving and bracing the wiper blade (11a) have slots (50), wherein said slots (50) are positioned such that a resilient cross-sectional structure is created, wherein said resilient cross-sectional structure has the form of at least one rib (52).

6. The connecting piece of claim 5, characterized in that a plateau (53) defines a direction to the at least one rib (52) having an angle less than 90°

.

7. The connecting piece of claim 1, characterized in that the body or the means for receiving and bracing the wiper blade (11a) has at least one elastic projection with at least one protuberance (24) for locking the wiper arm (11).

8. The connecting piece of claim 1, characterized in that the body or the means for receiving and bracing the wiper blade (11a) has at least one element (56) for limiting a twist angle between the wiper arm (11) and the wiper blade (11a).

9. The connecting piece of claim 1, characterized in that the body and the means for receiving and bracing the wiper blade (11a) have at least one element (56) for limiting a twist angle between the wiper arm (11) and the wiper blade (11a).

10. A connecting piece (10) for connecting a wiper blade (11a) to a wiper arm (11), having a body that receives an end of the wiper arm (11), and having means for receiving and bracing the wiper blade, characterized in mat on the body and on the means for receiving and bracing the wiper blade, region, (38, 41, 49) are provided, which are formed in yielding fashion for dimensional and tolerance compensation, wherein at least one of said yielding regions (38, 41, 49) is a resilient tab (38), said resilient tab (38) having at least two faces (40a, 13), wherein said at least two faces form stops for differently sized wiper arm ends (11) and wherein said at least two faces each can be transposed upon installation.
