US 6,279,193 B1 · Secondary wiper to a windshield wiper

Abstract

A secondary wiper to a windshield wiper is provided. The secondary wiper is detachably connected through connectors to an arched arm of the windshield wiper to locate in front of the latter relative to a sweeping direction of the windshield wiper. The secondary wiper includes a hair holder to which multiple lines of hair and a long wiping element are held. When the windshield wiper and the secondary wiper are brought to sweep across a windshield, the multiple lines of hairs on the secondary wiper first sweep granular and/or powdered dust off the windshield, so that such dust would not be brought by the windshield wiper to scrape across and damage the windshield. When the wipers are brought to reversely sweep across the windshield, the long wiping element on the secondary wiper effectively scrape watermarks off the windshield to enhance an overall function of the windshield wiper. A damaged secondary or windshield wiper may be independently replaced with a new one without the need to discard the other good wiper at the same time.
