ABSTRACT:
A windshield wiper device includes an oscillating wiper blade supported on a wiper arm which oscillates together with the wiper blade on the windshield to be wiped and is connected with a drive which imparts to the wiper arm a longitudinal displacement during the oscillating motion. The drive includes a gear, a stationary toothed segment meshed with the gear, and a crank mechanism having a crank and a driving rod connected to the crank. An intermediate drive is provided between a reciprocating element connected to the wiper arm and the driving rod of the drive to enlarge a path of the translatory movement of the driving rod.
