ABSTRACT:
The invention starts with a wiper arm (10), which includes a fastening part (14) and an articulated part (16) with a wiper rod (18), of which at least one part (14, 16, 18) is fabricated of sheet metal by stamping and bending and features at least one area with several sheet metal layers (26, 28). It is proposed that an external sheet metal plate (26) and an internal sheet metal plate (28) lying on top of one another are jointly bent around a bending edge (52), whereby the external sheet metal plate (26) features connecting toes (32) on its side edges (54) that run longitudinally to the bending edge (52), which engage in matching recesses (30) on the corresponding side edges (56) of the internal sheet metal plate (28), and, after bending under an initial tension, the internal sheet metal plate (28) is adjacent to the external sheet metal plate (26).
