Abstract: The invention proposes a motor vehicle screen wiper of the type comprising at least one elongate element, made of press-formed and bent sheet metal, and having, in cross section through a transverse plane, the form of an inverted U which comprises two vertical side portions joined together through a spine portion, in which, in one of the end portions of the elongate element, the spine portion has a zone of locally reduced thickness, such as to give a curvature to the external face of the elongate element in its end portion.

Abstract: A screen wiper apparatus, especially for motor vehicles, is of the type comprising a screen wiper arm and a wiper blade secured removably to one end of the arm by means of a coupling piece. The coupling piece has a recess for accommodating the wiper arm, together with articulating means which cooperate with complementary hook means on the wiper blade. The coupling piece is resiliently deformable so that it can be fitted between the side portions of the middle part of the main yoke of the blade. The coupling piece comprises two resiliently deformable side walls which are joined together by a bridge element on the same side as the engagement of the coupling piece with the wiper arm, the side walls being joined together on the opposite side by a transverse wall.

Abstract: A screen wiper, especially a motor vehicle windshield wiper, comprises a first element having a U-shaped cross section and a second element received in the U-shaped cross section of the first element, together with an insert piece which is interposed between the first and second elements. The insert piece has side walls which are formed with annular locating bushes. One of the two elements between which the insert piece is interposed has a hole formed through its side walls, this hole being open to a terminal edge of the side wall through an aperture or slot.
