Abstract

A wiper blade support is joined to a wiper arm by a yielding mechanism that maintains the two in a fixed angular relation during normal wipe, but which yields to allow the wiper blade to move more closely parallel to the windshield lower edge at park. The yielding mechanism includes a leaf spring indirectly joined between the wiper arm and blade support which buckles only when the wiper blade hits the lower edge of the windshield, allowing the compensating blade rotation, but remains flat during normal wipe.
