Abstract
A windshield wiper blade and an attachment therefor in which a body of porous material is supported on the blade at each side of the wiping edge thereof and which bodies engage the windshield when the wiper blade deflects laterally when in use. The porous material is laden with a cleaning agent which assists in cleaning the windshield. The bodies may be interconnected and form a single body and are detachably connected to the wiper blade.
Claims9
A windshield wiper assembly comprising resilient mounting means, a wiper blade of resilient material having a base portion secured to said resilient mounting means, a central longitudinal web integral with said base portion and a longitudinal wiping portion integral with said longitudinal web and engageable with the surface of a windshield, said wiping portion being wider than said web and spaced from the base, auxiliary wiper means mounted on said wiper blade comprising a supporting wiper structure extending the length of said wiper blade on each side of said wiping portion to form a frame having longitudinal elements spaced by less than the width of said wiping portion, with each of said elements fixed to and supported by said web on each side between said base portion and said wiping portion, and an auxiliary wiper body of resilient material secured on said element on each side, said auxiliary wiper body being of less height from said element than said wiping portion and formed with an edge for engagement with the surface of the windshield, said central longitudinal web flexing under engagement of said wiping portion with the surface of the windshield to cause engagement of one of said auxiliary wiper bodies on one side of said wiping portion with said surface, and connecting elements extending between said base portion of said wiper blade and underlying said wiper structure elements on opposite sides of said wiping portion to retain said supporting wiper structures on said wiper blade while allowing flexing of said central web with said wiping portion and said supporting structures.
A windshield wiper assembly comprising resilient mounting means, a wiper blade of resilient material having a base portion secured to said resilient mounting means, a central longitudinal web integral with said base portion and a longitudinal wiping portion integral with and wider than said longitudinal web and engageable with the surface of a windshield, said blade having grooves along opposite sides between said wiping portion and said base, metal plate means on opposite sides of said blade supported by said blade and including means to fix their edges in said grooves, longitudinal wiper bodies secured to said metal plate means on opposite sides of said blade, said wiper bodies being of less height from said metal plate means than said wiping portion, so that a wiper body on one side engages said windshield when said blade is deformed by engagement of said wiper portion with the surface of said windshield, each said wiper body having wiping edges formed as parallel projections spaced along said each body, and at an angle to the longitudinal side of said body, and connecting elements retaining said metal plate means on said blade.
