Abstract
Wiper spring is made of a length of spring wire having hook-like end portions at opposite ends. One of the end portions is shaped to slide over the drive arm of a vehicle wiper assembly from one side. The other end portion is shaped to hook over the wiper arm of the vehicle wiper assembly for applying additional spring force to the wiper arm to maintain better contact of the wiper blade against the surface being wiped during operation of the wiper assembly.
