Windshield wiping system

A wiper system comprising:

• a first wiper;
• a second wiper;
• a windshield wiper drive linkage coupled to said first and second wipers;
• a drive motor coupled to said windshield wiper drive linkage;
• and
• said windshield wiper drive linkage comprising:
• a plurality of linkage arms coupled to said first and second wipers and said drive motor;
• at least one of said plurality of linkage arms comprising a flexible arm which bends to facilitate preventing damage to components in said wiper system when a compressive load applied to said at least one of said plurality of linkage arms exceeds a predetermined load as a result of a fatigue condition;
• wherein said compressive load remains substantially constant as said flexible arm shortens at least 5 mm after said compressive load achieves said predetermined load.

A wiper system comprising:

• a first wiper;
• a second wiper;
• a windshield wiper drive linkage coupled to said first and second wipers;
• a drive motor coupled to said windshield wiper drive linkage;
• and
• said windshield wiper drive linkage comprising:
• a plurality of linkage arms coupled to said first and second wipers and said drive motor;
• at least one of said plurality of linkage arms comprising a flexible arm which bends to facilitate preventing damage to components in said wiper system when a compressive load applied to said at least one of said plurality of linkage arms exceeds a predetermined load as a result of a fatigue condition;
• wherein said flexible arm comprises a first end and a second end, said first and second ends are each over-molded with a connector, said ends comprising at least one shear groove such for enabling said connector to separate from said first or second end if said compressive force exceeds a maximum load for said flexible arm.
