Matador
has established a design for wrap-over windscreen wiper arms that provides the
facility for engagement with the under-hook method of attachment to the wiper
blade. The blade interface mechanism provides a positive method of engagement
and integrates with a unique multi jet washer fluid spray nozzle. A further
unique feature is the incorporation of an anti lift off device that prevents
the wiper arm and blade being lifted off the screen during high speed driving
or by the action of bus or coach washing machine when the vehicle is driven
through it. In this latter case it prevents the arms from crashing onto the
screen causing damage after the brushes release their grab on the arm and blade
assembly.
It will be seen from the pictures that the wiper arm has been designed and
manufactured in such a manner that it presents a pleasing smoothness of profile
and stylish appearance that complements the front of the vehicle. The arm
is finished in a semi-matt black colour process achieved by the electrophoretic
paint deposition process coupled with a further protective surface that prevents
discolouration by ultra violet light.
Exhaustive testing has been carried out on accelerated life test rigs giving
rise to exceptional durability performance standards that more then exceed
any known OEM specification. These tests have been further supported by road
trials on high speed coach applications where corresponding results have also
been achieved.
