Improvements relating to wiper blade rubbers

A wiper blade rubber has a head portion 1 and a wiper body 2 provided with a tip 3 which will carry out the wiping function. A neck 4 is defined by grooves 5 cut into both sides of the wiper blade rubber. In order to increase the length of the neck 4, portions of the wiper blade rubber are cut away at 6 into the head portion 1.
