Abstract
A wiper apparatus for a vehicle windshield has a wiper arm pivot rotatably mounted in a pivot holder fixedly secured to vehicle structure. An end portion of the wiper arm pivot normally extends exteriorly of an impact line defined by surrounding vehicle structure. The wiper arm pivot is axially displayable relative to the pivot holder upon the imposition of an impact load on the exposed end of the wiper arm pivot. An axial displacement biasing member is coupled to the wiper arm pivot for normally biasing the wiper arm pivot to a normal wiper arm wiping position. The axial displacement member returns the wiper arm pivot to the nominal wiping position after the impact load causing axial displacement of the wiper arm pivot has been removed from the wiper arm pivot.
