A fastening part for a wiper arm of a vehicle wiper is disclosed, which can be driven for the pivoting motion and which has a receptacle for the articulated connection of the wiper arm (11). For the sake of economical production of a lightweight fastening part of adequate rigidity, the fastening part is embodied as a sheet-metal part (17), with a substantially flat back (171) located in the pivoting plane and two side cheeks (172, 173), protruding approximately at right angles from the back, and a transverse reinforcement (21), which braces the upper edges (172 a, 173a), remote from the back, of the side cheeks ( 172, 173) against one another is disposed in the transition region from the side cheeks (172, 173) to the ears (18, 19), in which the articulated connection of the wiper arm (11) to the fastening part is made (FIG. 2).

The invention claimed is: 1. A fastening part for a wiper arm of a vehicle wiper, which is drivable for a pivoting motion and which has a recess for an articulated connection of the wiper arm (11), characterized by a sheet-metal part (17) having an essentially flat back (171) located in the pivotin
The invention claimed is: 1. A fastening part for a wiper arm of a vehicle wiper, which is drivable for a pivoting motion and which has a recess for an articulated connection of the wiper arm (11), characterized by a sheet-metal part (17) having an essentially flat back (171) located in the pivoting plane and two side cheeks (172, 173) protruding approximately at right angles from the flat back, which cheeks, on the end of the sheet-metal part (17) toward a wiper arm receptacle, merge with protruding ears (18, 19) that carry the receptacle, and by a transverse reinforcement (21), in the transition region from the side cheeks (172, 173) to the ears (18, 19), mat braces the upper edges (172 a, 173a), remote from the back, against one another, wherein the transverse reinforcement (21) includes a first tab ( 22), which is bent over approximately parallel to the back (171 ) at the upper edge (172) of one side cheek (172), and a second tab (23), which is bent over until it rests on the first tab (22) at the upper edge (173a) of the other side cheek (173), and which second tab has claws (24), bent over from its two longitudinal edges, which claws are pressed against the first tab (22). 2. The fastening part of claim 1, wherein the first tab ( 22) has lateral recesses (25), in which the bent-down claws (24) on the second tab (23) dip. 3. The fastening part of claim 2, wherein the boundary edges (251, 252), oriented toward one another, of the recesses (25) are chamfered such that their spacing from one another decreases toward the bottom (253) of the recess (25). 4. The fastening part of claim 1, wherein the first tab ( 22) extends to near the opposite side cheek (173). 5. The fastening part of claim 1, wherein the sheet-metal part (17), with ears (18, 19), tabs (22, 23), recesses (25), and claws (24), is stamped out of a sheet-metal blank and deep-drawn for forming the side cheeks (172, 173).
