Abstract
A windshield wiper apparatus for a vehicle having a pivot lever, a linkage, and a rotating mechanism which is operative to move windshield wipers to and from storage and operating positions is provided. The pivot lever is secured at an end thereof to a pivot shaft which supports a wiper arm, and is coupled at the other end thereof to a link rod connected to a wiper motor which pivotally drives the wiper arm. The linkage includes a first link which is coaxially connected to the pivot shaft, a second link which is connected to the link rod and is substantially parallel to the first link, and a third link which is connected at an end thereof to the first link and connected at the other end thereof to the second link and the link rod to reciprocally rotate the pivot shaft. The rotating mechanism is interlocked to the first link to hold the first link at a predetermined wiping position during the normal operation of the wiper and to rotate the first link to a predetermined storage position when the wiper is not in use.
