摘要： A windshield wiper blade comprises a composite supporting bracket frame pivotally connected with a driven wiper arm and including a plurality of frame components, at least some of the components being provided with holding claws, and elongated wiper strip composed of an elastic material and guided in the holding claws, the wiper strip having a strip back which is engaged by the holding claws and has end portions extending outwardly beyond the claws and a longitudinal opening, the wiper strip having a longitudinal wiper lip adapted to abut against a windshield to be wiped and an elastic reinforcing rail received in the longitudinal opening of the strip back and having a length substantially corresponding to a length of the wiper strip, the longitudinal opening of the strip back being formed as a circularly closed throughgoing passage with a cross-section corresponding to the cross-section of the reinforcing rail, the reinforcing rail having at least one longitudinal side provided with two expansions which are spaced from one another and extending outwardly beyond its cross-section so as to form securing means for securing the wiper strip on the supporting bracket frame and holding the reinforcing rail in the strip back, the expansions being spaced from one another by a distance which is greater than the width of one of the holding claws in a longitudinal direction on the wiper strip, so that in a finally mounted condition the holding claws of the wiper strip engage between the expansions.
