Abstract:
1. Method for adjusting a wiping angle (φ 1 , φ 2 ) between a park position and a reversal position ( 28 , 30 ) of a wiper lever ( 16 , 18 ) of a windshield wiper system for a motor vehicle with at least one wiper lever ( 18 ) whose park position or reversal position ( 30 ) runs approximately parallel to an A pillar ( 14 ) of a vehicle body, which laterally delimits a windshield ( 10 ), wherein the wiping angle (φ 2 ) is adjusted by means of an eccentric ball pivot ( 60 ), which is arranged on a free end of a driving crank ( 54 ) and connects the same to a motor crank ( 52 ) in an articulated manner by means of an articulated rod ( 42 ), while the other end of the driving crank ( 54 ) sits on a drive shaft ( 56 ) in a rotationally fixed manner, said drive shaft driving a fastening part ( 58 ) of the wiper lever ( 18 ), characterized in that the windshield wiper system is first mounted on the vehicle body without the eccentric ball pivot ( 60 ), that a rivet journal ( 64 ) of the eccentric ball pivot ( 60 ) is then axially inserted fully into a corresponding bore hole of the driving crank ( 54 ), that, with the rivet journal ( 64 ) of the eccentric ball pivot ( 60 ) fully axially inserted in the corresponding bore hole, the optimum wiping angle (φ 2 ) is determined and adjusted by modifying the effective radius ( 78 ) between an articulation axis ( 66 ) of the eccentric ball pivot ( 60 ) and an axis ( 76 ) of the drive shaft ( 56 ) by rotating the eccentric ball pivot ( 60 ) around an axis ( 68 ) of the rivet journal ( 64 ), and that finally the rivet journal ( 64 ) is non-adjustably fixed in the driving crank ( 54 ) in an adjusted position to non-adjustably fix the wiping angle of the wiper lever.
