  • Windshield wiper drive linkage arm with grooves
    Patent number: 7059009
    Abstract: This invention relates to windshield wiper system and method which utilizes a flexible member to account for compression loads in excess of a predetermined load, such as 30 percent greater than a maximum load for the flexible member. The system utilizes a flexible pultruded composite material having a relatively low modulus of elasticity, yet relatively high elongation characteristics. The flexible arm bends to facilitate preventing damage to components in the wiper system when a compressive load applied to the flexible member reaches a predetermined load as a result of a fatigue condition, such as snow or ice build up on the windshield. In one embodiment, the predetermined load is defined as: PCR=KE=1.
