  • WINDSHIELD WIPER SYSTEM WITH TUBULAR MEMBER PLUS INTERNAL HOSE
    Publication number: 20070240274
    Abstract: This invention relates to windshield wiper system and method which utilizes a flexible drive arm for withstanding bending loads applied to a wiper. The drive arm may be made of a pull-molded composite material having a relatively low modulus of elasticity and a relatively high elongation factor. The flexible arm twists in the presence a bending load and undergoes rapidly progressing elastic buckling when the bending load exceeds a predetermined amount.
    Type: Application
