ABSTRACT:
A backing strip for a windscreen wiper blade assembly, and a clip for securing the backing strip to the assembly are disclosed. The backing strip and clip may be used in a wiper refill replacing existing windscreen wiper blades or may be provided as original equipment. The backing strip comprises rails (20) and (22) which can be engaged with claws (12) of the wiper assembly. The backing strip has two channels (34) and (36) for receiving a wiper element (40) and either rails (20) or (22) can be engaged with the claws depending on the size of the claws. The wiper element (40) is arranged in an appropriate one of the channels (34, 36) depending on which of the rails (20, 22) are engaged with the claws. The backing strip may include a third pair of rails (102) for enabling the backing strip to be used with claws of three different sizes. A clip (50) is disclosed for retaining the backing strip to the assembly and comprises first and second pairs of legs (54) and (56) which are spaced apart different distances corresponding to the rails (20) and (22), the legs (54) and (56) have prongs (58) which engage behind the claws (12) to limit longitudinal movement of the backing strip relative to the claws (12).
