Abstract: A screen wiper intended to be detachably fitted on the end of a wiper arm, comprises a harness having means for attachment of the harness to said arm, an elastically deformable elongated piece having means along a portion thereof towards one end for supporting a portion of a wiper blade, and a yoke pivotally mounted towards the other end of said elongated piece for supporting the portion of the blade rubber not carried by the said elongated piece. By mounting the blade in this manner the blade can undergo independant deformation on each side of the articulation point of the wiper arm, which eliminates practically all risk of lift-away such as can occur with known wipers when they encounter zones of great curvature.

Abstract: A screen wiper blade with a replaceable rubber-blade comprises a deformable harness equipped with pairs of claws receiving the edges of a flexible vertebra on which a wiping blade rubber is mounted. The vertebra is constituted by an elongated thin metallic plate having a longitudinal slot over the major part of its length. The rubber blade is provided with a longitudinal bead turned towards the harness and separated from the body by a thin wall lodged in the said slot. Adjacent one of the extremities of the rubber blade and on the same side of the body as the bead is a nipple. The thin plate comprises at one extremity a cutaway portion forming a fork and the said nipple comprises in its lower part a groove facing the extremity of the blade rubber opposite to the said nipple, the said fork cooperating with the said groove.
