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 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.

The invention claimed is: 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). 2. Windscreen wiper device according to claim 1, characterized in that the distance between the two coupling points (A, B) can be modified as a function of the position of the wiper arm (18). 3. Windscreen wiper device according to claim 1, characterized in that the means (34) to modify the distance between the two coupling points include a rectilinear sliding joint. 4. Windscreen wiper device according claim 1, characterized in that both cranks (30, 32) are driven at least causally in a pendulum fashion. 5. Windscreen wiper device according to claim 1, characterized in that both cranks (30, 32) are connected at least indirectly by a thrust rod (38) for transmitting movement between the cranks. 6. Windscreen wiper device according to claim 5, characterized in that at least one crank (30, 32) features a bend (44, 46) in the area in which the thrust rod (38) is linked. 7. Windscreen wiper device according to claim 1, characterized in that the wiper arm (18) features an articulated part (19) and a fastening part (21) and the coupling points (A, B) are arranged on the fastening part (21). 8. Windscreen wiper device according to claim 1, characterized in that in operation the wiper arm (18) executes at least one partial rotational movement around a rotational axis and the rotational axis of the wiper arm (18) is essentially perpendicular to the surface that is covered by the wiper arm (18) in operation at a minimum of one, preferably at both coupling points (A, B). 9. 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 two fastening points that are different from the coupling points (A, B), characterized in that means (34) are provided to modify the distance between the two coupling points (A, B), characterized in that both cranks (30, 32) are connected at least indirectly by a thrust rod (38), and characterized in that at least one crank (30, 32) features a bend (44, 46) in the area in which the thrust rod (38) is linked. 10. 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 first and second cranks (30, 32) are linked at respective first and second fastening points that are different from the coupling points (A, B), the first fastening point being spaced from the second crank and the second fastening point being spaced from the first crank, characterized in that means (34) are provided to modify the distance between the two coupling points (A, B). 11. Windscreen wiper device according to claim 10, characterized in that the distance between the two coupling points (A, B) can be modified as a function of the position of the wiper arm (18). 12. Windscreen wiper device according to claim 10, characterized in that the means (34) to modify the distance between the two coupling points include a rectilinear sliding joint. 13. Windscreen wiper device according claim 10, characterized in that both cranks (30, 32) are driven at least causally in a pendulum fashion. 14. Windscreen wiper device according to claim 10, characterized in that both cranks (30, 32) are connected at least indirectly by a thrust rod (38) for transmitting movement between the cranks. 15. Windscreen wiper device according to claim 14, characterized in that at least one crank (30, 32) features a bend (44, 46) in the area in which the thrust rod (38) is linked. 16.
