The invention relates to a wiper arm (10), in particular for a motor vehicle, comprising at least one fixing part (12) that can be fixed to a shaft, a support part (14), to which a wiper blade can be fixed (16) and a spring part (18). The spring part (18) is configured as a bar spring, which connects the fixing part (12) to the support part (14). The fixing part (12) and the support part (14) are configured from plastic and the fixing part (12) and/or the support part (14) are fixed to the spring part (18) by means of a deformation. The invention also relates to methods for producing an inventive wiper arm, according to which the deformation connection is established by friction welding or ultrasonic welding. |
