Abstract

The invention relates to an arrangement for fixing a windscreen wiper blade (1, 3, 5, 4) to a wiper arm (2). The aforementioned blade (1, 3, 5, 4) comprises a through transverse swivel pin which is intended to form a pivot connection with the arm and said arm (2) is equipped with an end rod. According to the invention, the arrangement comprises an independent piece (6), known as an adapter, which is mounted on the blade (1, 3, 5, 4) and the above-mentioned rod is inserted longitudinally therein.

Claims

1. An arrangement for fixing a windscreen wiper blade on an arm, the said blade having a through transverse pivot spindle intended for the pivoting connection with the said arm and the said arm having an end rod, characterised in that it comprises an independent piece referred to as an adapter mounted on the said blade and in which the said rod is fitted longitudinally.

2. The arrangement according to claim 1, characterised in that he said adapter has a substantially U-shaped cross section whose flanges each have an orifice for snapping onto the said spindle and an end of which, referred to as the entry end, is open and in that the said adapter comprises means for the trasverse and longitudinal locking of the said arm.

3. The arrangement according to claim 2, characterised in that a longitudinal locking means consists of an articulated part provided with a tenon fitted in an orifice arranged on the rod, when the latter is fitted.

4. The arrangement according to claim 3, characterised in that this locking means consists of a cross-member aritcualted on the adapter by means of at least one flexible tongue, carrying the said tenon and forming, with the web of the adapter at its entry end, a positioning channel for the rod.

5. The arrangement according to claim 2, characterised in that a longitudinal locking means consists of the housing arranged on the adapter in which a stop on the rod comes into engagement, when the latter is fitted.

6. The arrangement according to claim 5, characterised in that the said housing is arranged on the web of the adapter close to its end opposite to the entry end and the said stop arranged at the end of the rod.

7. The arrangement according to claim 6, characterised in that the said housing is conformed by virtue of a profiled snapping-in rib on the internal surface of the adapter and the said stop is a profiled catch at the end of the rod.

8. The arrangement according to claim 2, characterised in that the adapter has at least one fixed cross-member for the transverse locking of the rod.

9. The arrangement according to claim 2, characterised in that the web of the adapter is provided with a longitudinal opening allowing passage of the rod when it is fitted.
