Patent ID: 7420346

Claim:
Drive arrangement of a wiper device for windows of motor vehicles with at least two swivel-mounted wiper arms ( 18 , 20 ) that are connected to one another via a crank mechanism, wherein one of the wiper arms ( 18 ) is directly coupled with a driven shaft ( 16 ) of an electromotive drive ( 10 ), characterized in that the electromotive drive ( 10 ) includes a uniformly transmitting gear ( 14 ) coupled to a driving motor ( 12 ), and wherein the uniformly transmitting gear ( 14 ) includes the driven shaft ( 16 ), characterized in that an electric driving motor ( 12 ) of the drive ( 10 ) features rotational direction reversal, characterized in that a reversal of the rotational direction of the electromotive drive ( 10 ) is provided for at each end of travel of the wiper arms ( 18 , 20 ), characterized in that the electromotive drive ( 10 ) features a sensory mechanism to detect the end of travel, characterized in that the electromotive drive ( 10 ) features a speed control, characterized in that the speed control always provides for a reduction in the rotational speed of the drive ( 10 ) near the ends of travel of the wiper arms ( 18 , 20 ), characterized in that at least two wiper arms ( 18 , 20 ) are coupled via a crank and rocker linkage ( 30 ), characterized in that both of the wiper arms ( 18 , 20 ) feature a path of motion in the same direction, characterized in that at least two wiper arms ( 18 , 20 ) feature an approximately parallel path of motion.
