Abstract

A low overall height is provided in a wiper-arm assembly with a wiper arm which has a fastening part, a link part which is swivelably linked to the fastening part and two side walls and a back connecting the two side walls, and a contact pressure spring which is accommodated in the link part and acts on the link part and the fastening part, and also with a wiper blade linked to the wiper arm, which blade lies at least partly in line with the link part. The low height is achieved by making the clearance between the contact pressure spring and the one side wall of the link part greater than the width of the wiper blade in the area of the link part and by the wiper blade being swivelable into the link part alongside the contact pressure spring.
