Abstract
A vehicle wiper blade comprises a yoke which is advantageously made of a plastic material and is provided with means such as a mounting pin for pivotally mounting it on a wiper arm. The underside of the yoke includes downwardly extending and laterally offset pairs of depending arms which extend downwardly and inwardly from respective sides of the yoke to form a supporting surface spaced from the bottom of the yoke. A wiper blade includes a web portion with a flat surface which is disposed between the support surface and the bottom of the yoke and a blade which projects downwardly between the supporting elements of the yoke for engagement with the windshield. A spring member is inserted between the web of the blade and the bottom of the yoke and both the spring member and the table web portion are provided with a cutout area which aligns beneath a slot defined through the yoke. A locking clip is inserted into the slot and into the cutout area of the spring and the blade and is resiliently engaged with the yoke and holds the blade and the spring in position in respect to the yoke.
