The invention relates to a wiper system for the front windscreens of motor vehicles. Said system comprises at least one wiper blade, which can be guided over the front windscreen (4) on a pivotable wiper arm (11), at least one bearing part (1) that can be pivoted about an axis (5), at least one fixing part (10) that can be connected to the bearing part (1) in a non-torsional manner and at least one single-axis articulation that connects the wiper arm (11) to the fixing part (10). The position of the connection between the bearing part (1) and fixing part (10) lies in the vicinity of the axis (5) about which the bearing part (1) is pivoted.

1. A wiper system for front windshields of motor vehicles, comprising at least one wiper blade which can be guided over the front windshield (4) on a pivotable wiper arm (11), at least one bearing part (1) which can be pivoted about an axis (5), at least one fastening part (10) which can be connecte
1. A wiper system for front windshields of motor vehicles, comprising at least one wiper blade which can be guided over the front windshield (4) on a pivotable wiper arm (11), at least one bearing part (1) which can be pivoted about an axis (5), at least one fastening part (10) which can be connected to said bearing part (1) in a manner secure against rotation, and at least one single-axis articulation part which connects the wiper arm (11) to the fastening part (10) for permitting articulation about an axis of articulation (14), wherein a position of the connection of bearing part (1) and fastening part (10) is located next to the axis (5) about which the bearing part (1) is pivoted, characterized in that the bearing part (1) comprises a bearing bushing (2) which is placed pivotably onto a positionally fixed bearing shaft (3), with a lever (8) and a support structure (6) extending perpendicularly to the pivot axis (5) with the support structure extension defining a main axis, said support structure being connected to the bearing bushing (2) and being connected outside the pivot axis (5) to a fastening means (7) to which the fastening part (10) of the wiper arrangement can be fastened, wherein said lever (8) on which a wiper linkage acts is connected to the bearing bushing (2), wherein the supporting structure (6) and the lever (8) are adjusted essentially into the same direction, wherein the axis of articulation (14) of the articulation part deviates from a perpendicular to a main axis (15) of the wiper arm (11) in a plane in which the fastening part (10) is pivoted, wherein the axis of articulation (14) of the articulation part is substantially perpendicular to the main axis of the support structure (6). 2. The wiper arrangement as claimed in claim 1, characterized in that the fastening means (7) comprises a bolt-shaped bearing shaft (7′), the fastening part (10) has a fastening opening (16) into which the bolt-shaped bearing shaft (7′) can be introduced and means (20, 20′) are included which permit a rotationally secure but adjustable fastening of the fastening part (10) to the bolt-shaped bearing shaft (7′). 3. The wiper system as claimed in claim 2, characterized in that the axis (5) about which the bearing part (1) is pivoted runs through the front windshield (4), with the positionally fixed bearing shaft (3) being arranged in a vehicle interior without touching the front windshield (4), and the fastening means (7) to which the fastening part (10) of the wiper arrangement can be fastened being located next to the front windshield (4) in every pivoting position of the bearing part (1). 4. The wiper system as claimed in claim 3, characterized in that the deviation between the axis of articulation (14) of the articulation part and the perpendicular to the main axis (15) of the wiper arm (11) in the plane in which the fastening part (10) is pivoted lies within the range of between 5° and 45°. 5. The wiper system as claimed in claim 3, characterized in that the deviation between the axis of articulation (14) of the articulation part and the perpendicular to the main axis (15) of the wiper arm (11) in the plane in which the fastening part (10) is pivoted lies within the range of between 5° and 30°. 6. The wiper system as claimed in claim 5, characterized in that the articulation part comprises two eyes through which bearing bolts (13, 13′) are guided. 7. The wiper system as claimed in claim 6, characterized in that the articulation part is connected nonreleasably to the wiper arm (11) and/or to the fastening part (10). 8. The wiper system as claimed in claim 7, characterized in that at least one wiper blade can be moved between a steep end position in a sharply curved border region of a wraparound windshield (4′) and a flat end position in a central, more gently curved region of the wraparound windshield (4′). 9. The wiper system as claimed in claim 1, characterized in that the axis (5) about which the bearing part (1) is pivoted runs through the front windshield (4), with the positionally fixed bearing shaft (3) being arranged in a vehicle interior without touching the front windshield (4), and the fastening means (7) to which the fastening part (10) of the wiper arrangement can be fastened being located next to the front windshield (4) in every pivoting position of the bearing part (1). 10. The wiper system as claimed in claim 9, characterized in that at least one wiper blade can be moved between a steep end position in a sharply curved border region of a wraparound windshield (4′) and a flat end position in a central, more gently curved region of the wraparound windshield (4′). 11. The wiper system as claimed in claim 1, characterized in that the deviation between the axis of articulation (14) of the articulation part and the perpendicular to the main axis (15) of the wiper arm (11) in the plane in which the fastening part (10) is pivoted lies within the range of between 5° and 45°. 12. The wiper system as claimed in claim 1, characterized in that the deviation between the axis of articulation (14) of the articulation part and the perpendicular to the main axis (15) of the wiper arm (11) in the plane in which the fastening part (10) is pivoted lies within the range of between 5° and 30°. 13. The wiper system as claimed in claim 1, characterized in that the articulation part comprises two eyes through which bearing bolts (13, 13′) are guided. 14. The wiper system as claimed in claim 1, characterized in that the articulation part is connected nonreleasably to the wiper arm (11) and/or to the fastening part (10).
