Improvement of wiping ratio with low-speed by use of "wide view wiper system"

Satoh, S. / Satoh, H.

This article introduces ''wide view wiper system'' which will be able to eliminate the deviation of wiping area between low-speed and high-speed. This system will consist of a structure wherein the actual length of motor arm will become longer at low-speed mode and shorter at high-speed mode through switiching an eccentric bearing that is built-in with the motor arm. This eccentric bearing will be switched automatically following motor rotation direction when speed mode will be changed. As a result, this wiper system will be able to realize the high wiping rate at low-speed operation mode and the lower park position of wiper arm and blade to improve the vehicle appearance. This system is able to reduce the un-wiped area at pillar side, which is the most important factor to be considered for the several drivers. It is more important for driver side compared with reducing the un-wiped area at upper area of passenger side. Recently, drivers are also interested in the effect of lowering park position. It is a high value-added system.
