Windshield Wipers

     The rear wiper is usually used on one-box or two-box cars or, in general，by vehicleson which the backlight aerodynamic flow exhibits heavy turbulence and therefore sprayswater and mud from the wheels onto the back of the vehicle, while the boundary air speedis too low to clean off drops of dirty water.

    The primary task of the windshield and rear wiper, to be considered also in terms ofcontributing to accident prevention, is to enable an acceptable outside visibility, wiping offwater, mud or snow from the front and rear glass surfaces.  With additional watersprayers，wipers must be able to clean the same surfaces，even if splashed by powder,mud or other solid contaminants. Being a part of the vehicle safety system, wipers mustcomply with international regulations.
