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.
Claims8
A screen wiper main yoke for a motor vehicle screen wiper assembly comprising an elongate element having a transverse U shape, the transverse U shape defining two transversely spaced side portions each of said side portions having a predetermined thickness and a spine portion having an outer face and joining the side portions together, the elongate element having an end portion in which the spine portion defines a zone of thickness that is less than one of the respective side portion thicknesses, said spine portion zone establishing an outer face of the spine portion that is curved convexly in the direction of elongation of the element, said spine portion having a transverse terminal edge in the end portion, the terminal edge having an integral lug for hooking engagement with a sound deadening element.
A main yoke for a motor vehicle screen wiper assembly, said yoke comprising an elongated element having in transverse cross section a U-shape, the U-shape defining two transversely spaced side portions, each of said side portions having a predetermined thickness and a spine portion having an outer face and joining the side portions together, the elongate element having an end portion in which the spine portion defines a zone of thickness that is less than one of the respective side portion thicknesess, said spine portion zone establishes an outer face of the spine portion that is curved convexly in the direction of elongation of the element, a sound deadening element having a body portion mounted within the elongate element at the end portion thereof, the sound deadening element having an external form that matches the elongate element in which the sound deadening element is mounted, the sound deadening element having a terminal portion constituting a longitudinal extension of the elongate element, the terminal portion of the sound deadening element being complementary to the external convex curvature form of the elongate element in the end portion of the elongate element and said terminal portion having a terminal flange portion defining an aperture through it.
