Abstract
A windshield wiper arrangement includes a mounting for a drive containing a wiper motor, a gear unit and a lever arm and two bearing brackets, spaced from the drive, containing wiper arm drive shafts each carrying an oscillating lever connected by a link rod to the lever arm. The mounting is an integral tubular structure shaped by high pressure forming of a tubular blank placed in a two-part mold having recesses extending essentially perpendicularly to the axis of the tubular part. Bushings for the drive shafts and a mount for the drive are forced into projections which are formed in the recesses when the tubular blank is shaped.
