Abstract

The present invention relates to a windscreen wiper that includes a unitary elongate curved beam and a rubber blade mounted to the beam. The beam has a protective end formation located at at least one of its tips. The end formation comprises a deformed end portion of the beam which projects beyond the end portion of the rubber blade.

Claims

1. A windscreen wiper (10) for a windscreen comprising a unitary elongate curved beam (12) with a top side facing away from the windscreen and a bottom side facing toward the windscreen, and a rubber blade (14) mounted to the beam (12) such that a top side of the rubber blade (14) is in planar abutment against the bottom side of the beam (12), the beam (12) having a protective end formation (16) at at least one of its tips (18), characterised therein that the curved beam (12) has a varying thickness and that the end formation (16) comprises a deformed end portion of the beam (12), which projects beyond and is spaced from an end portion of the rubber blade (14) to define a gap between the end portion of the rubber blade and the deformed end portion wherein an axis extending perpendicularly from the end portion of the rubber blade passes through the gap and the deformed end portion.

2. The windscreen wiper (10) as claimed in claim 1, characterised therein that the beam (12) has a pair of end formations (16), one at each tip (18).

3. The windscreen wiper (10) as claimed in claim 2, characterised therein that each end portion is folded over.

4. The windscreen wiper (10) as claimed in claim 1, characterised therein that the beam (12) has a free form curvature in a plane.

5. The windscreen wiper (10) as claimed in claim 1, characterised therein that the beam (12) has a compound curvature.

6. The windscreen wiper (10) as claimed in claim 1, characterized therein that the rubber blade (14) is mounted directly to a bottom side of the beam (12).
