Windscreen wiper device, in particular for a motor vehicle
First Claim
1. Windscreen wiper device, in particular for a motor vehicle, with a wiper arm (18), which is able to support at least one wiper blade (22) and is fastened so that it can move in a rotating fashion at a minimum of one first coupling point (A) by means of a first crank (30) and at a second coupling point (B) that is different from the first coupling point (A) by means of a second crank (32), and in addition the cranks (30, 32) are linked at respective and different fastening points that are different from the coupling points (A, B), the fastening points being fixed relative to the vehicle, characterized in that means (34) are provided to modify the distance between the two coupling points (A, B).

Abstract
A windscreen wiper device is shown, in particular for a motor vehicle, which features a wiper arm (18), which is able to support at least one wiper blade (22) and is fastened so that it can move in a rotating fashion at a minimum of one first coupling point (A) by means of a first crank (30) and at a second coupling point (B) that is different from the first coupling point (A) by means of a second crank (32). In addition, the cranks (30, 32) are linked at two fastening points that are different from the coupling points (A, B), whereby means (34) are provided to modify the distance between the two coupling points (A, B). In addition, a windscreen wiper device with a four-bar linkage is shown, whereby both cranks driving the wiper arm are causally driven.
