- This projection is for example obtained through orifices formed on the body 18 of the wiper blade 1.
- the invention aims to cover the process for melting gel and / or frost and / or ice and / or snow present on a window of a motor vehicle, using a broom wiper 1 arranged to supply heat to the window 2, according to a melting cycle associated with a rising phase or a downward phase of the blade, according to one of the three embodiments described above. It being understood that the description of the blade made with reference to FIGS. 5a, 5b and 6 is common to all these modes.
