Abstract
A wiper apparatus for motor vehicle windshields is proposed, said apparatus being provided with a driven wiper arm located on the motor vehicle body and movable between reversing positions, on whose free end is fixed one side of a joint pin whose axis extends transverse to the longitudinal axis of the wiper arm and essentially in the direction of movement of the wiper arm. On the joint pin is lodged a wiper blade capable of swinging about the joint axis, the wiper apparatus having means for securing the wiper blade on the joint pin. A particularly cost-effective wiper apparatus is obtained when the securing means for the wiper blade are disposed on the wiper arm and on the side of the wiper blade facing away from said arm cooperate with a stop located on the wiper blade side.
