  • Patent number: 4264997
    Abstract: A wiping arrangement for wiping a vehicle window has a rotatable output shaft, a wiper shaft connected with a wiping element, and pendulum elements for converting the rotary movement of the output shaft into the pendulum movement of the wiper shaft. The pendulum elements include a crank member connected with and rotatable by the output shaft, a rocker arm connected with the wiper shaft, and a connecting rod which is pivotally connected with the crank member and the rocker arm. Elements are provided which allow swinging of the connecting rod even when the wiper shaft is blocked, for example as a result of snow accumulation in the region behind the wiper shaft. Thus, the connecting rod can swing about a hinge which connects the same to the rocker arm, and thereby the crank member can rotate despite the blocking of the wiper shaft.
