  • Method for operating a dual sweep angle and indexable wiper system
    Patent number: 11173878
    Abstract: A windshield wiper assembly for a dual sweep angle and indexable wiper system is provided. The system includes a wiper motor and a wiper arm for sweeping a surface of a windshield coupled to a first eccentric, the first eccentric comprising a primary eccentric and an indexable eccentric plate, wherein the indexable eccentric plate determines an eccentric offset of the wiper arm coupled to the first eccentric. The system further includes an output wiper shaft coupled to the wiper arm, a second eccentric coupled to a cam shaft, and a link coupled to the first eccentric and the second eccentric, the link having a first effective link arm length between the first eccentric and the second eccentric for driving the first eccentric to operate the wiper arm when operated in a first direction.
