Abstract

A process of assembling a wiper system, in which, in a transport position, the wiper arms are fixed onto the wiper shaft in a simply releasable manner and then the unit, pre-assembled in such a way, is delivered to the manufacturer of motor vehicles. There the wiper arms are swivelled from their transport position into their operational position and are permanently fixed onto the proper wiper shaft. Matching the wiper arms to the wiper system during the transport effectively prevents the manufacturer of motor vehicles from assembling them wrongly.
