Wiper System Having Resilient Interface Assembly For Worm-Driven Reduction Gear Motor

A windshield wiper system comprising:

• at least one wiper assembly;
• a linkage assembly connected to said at least one wiper assembly;
• a worm-driven reduction gear motor having a housing, an output shaft rotatably supported by said housing, and a motor arm connected to said output shaft and said linkage assembly to drive said at least one wiper assembly in repeated wiping motion across a surface of a windshield;
• and
• a resilient interface assembly comprising a torus-shaped spring disposed about said output shaft between said housing and said motor arm to provide resistance to loading deflection and damp axial and cross-axial movement of said output shaft of said motor.

A windshield wiper system comprising:

• at least one wiper assembly;
• a linkage assembly connected to said at least one wiper assembly;
• a worm-driven reduction gear motor having a housing, an output shaft rotatably supported by said housing and having a tapered portion external to said housing, and a motor arm connected to said output shaft and said linkage assembly to drive said at least one wiper assembly in repeated wiping motion across a surface of a windshield;
• and
• a resilient interface assembly comprising a first washer disposed about said output shaft adjacent said housing, a second washer disposed about said output shaft adjacent said first washer, and a torus-shaped resilient member disposed about one axial end of said output shaft of said worm-driven reduction gear motor between said second washer and said motor arm to provide resistance to loading deflection and damp axial and cross-axial movement of said output shaft of said motor.
