Abstract

A wiper arm (10), in particular for a motor vehicle wiper system is proposed, having a pivot part (12) made of plastic, which has two ends and on a first end (16) can be connected to a wiper blade and also, on its second end (18) remote from the first end, is connected rotatably to a fastening part (14); the fastening part (14) is made of sheet metal.

Claims

1. A wiper arm (10) comprising an elongated pivot part (12) made of plastic, which has two ends and on a first end (16) can be connected to a wiper blade and also, on a second end (18) remote from the first end, is connected rotatably to a fastening part (14), wherein the fastening part (14) is made of sheet metal, wherein the pivot part (12), at least in a region of the second end (18), is shaped essentially in the form of an inverted U, and the fastening part (14) at least partly embraces the pivot part (12) in said region, wherein the pivot part (12) is tapered in a region of the second end (18), wherein at least one hinge pin (32) extends laterally outward from the tapered region, wherein the fastening part (14) at least partly embraces the pivot part (12) and has at least one U-shaped opening (30) that embraces the at least one hinge pin (32).

2. The wiper arm (10) of claim 1, wherein the pivot part (12) and the fastening part (14) are clamped together via at least one essentially straight spring element.

3. The wiper arm (10) of claim 1, wherein the tapered region, and in particular the hinge pin (32), has least one fastening element (48) for securing a guard cap (50).

4. The wiper arm (10) of claim 1, wherein the hinge pin (32) is braced in the direction of the first end (16) by at least one bracing element (44).

5. The wiper arm (10) of claim 4, wherein the at least one bracing element (44) acts as a stop for limiting a rotational angle.

6. The wiper arm (10) of claim 1, wherein the at least one hinge pin (32) does not extend through the pivot part (12).
