PCT No. PCT/EP90/00814 Sec. 371 Date Jan. 23, 1991 Sec. 102(e) Date Jan. 23, 1991 PCT Filed May 21, 1990 PCT Pub. No. WO90/14254 PCT Pub. Date Nov. 29, 1990.Pendulum gears for windshield wipers of motor vehicles are known, which pendulum gears comprise a first gear member provided with teeth, which gear member is non-rotatably seated on a driven shaft, and a second gear member provided with teeth, which gear member meshes with the first gear member, and by which the first gear member can be driven in pendulum motion between two reversing positions. The noises occurring in the reversing positions of the first gear member are to be reduced. For this purpose the tooth play between the teeth of the two gear members is decreased towards the reversing position of the first gear member. Thus a beating noise caused by the teeth when changing the tooth flanks is avoided.
