Reversible blade for windscreen wiper

摘要

The windscreen wiper blade comprises a support core to which are connected blade parts. These parts in cross-section have a parallel trapezoidal shape, the base of which is considerably wider than its top. The blade parts are pliable around a body to the extent that the top two edges are alternately in contact with the windscreen as the wiper blade goes backwards and forwards. The blade is produced from an extrudable material, with a large content of silicon.
