Windshield wiper assemblies, windshield wiper systems, and methods of controlling wiper blade sweep in windshield wiper systems

A method of controlling sweep of a windshield wiper, comprising:

• at a windshield wiper assembly including a wiper blade, an output shaft supported for rotation about a rotation axis, the wiper blade fixed in rotation relative to the output shaft, and a stop member arranged axially along the output shaft and extending radially from the output shaft, the stop member fixed in rotation relative to the output shaft, an output shaft supported for rotation about a rotation axis, wherein the wiper blade is fixed in rotation relative to the output shaft
• sweeping the windshield wiper within a predetermined sweep range by rotating the output shaft about the rotation axis;
• and
• limiting rotation of output shaft beyond the predetermined sweep range with the stop member.
