ABSTRACT:
A windshield wiper structure for vehicles includes a truss saddle, a bow elastic stripe, a cover body, some detachable clamping devices, a strip scraper and a frame cover. Hollow pressure adjusting vents are created on said bow elastic stripe in order to keep nearly the same elasticity at every section of said bow elastic stripe. Hence, force can be equalized in every portion of the whole wiper thereby achieving even pressure distribution. As a result, the contact between the strip scraper and the windshield glass is uniformly tight and hermetic to enhance the scraping effect of the windshield wiper as the effect of prolonging service-lifetime while reducing expenses associated with wiper replacement, thereby providing enhanced economy and environmental protection.
