Windshield wiper system having a tubular member having a foam core |
摘要 |
This invention relates to windshield wiper system 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.
