Abstract
A method for assembling a wiper blade with a wiper arm wherein the wiper blade consists of a backing strip having keyhole-shaped slots therein and an open aperture at one end of the strip, along with a multifarious wiping element having a plurality of T-shaped projections for fitting in the keyhole-shaped slots in the backing strip and a projection at the end thereof for buttoning the backing strip to the wiping element upon stretching the wiping element. The steps of the method define the sequence of steps of aligning the projections with the slots and stretching the wiping element to align the projection with the open aperture whereupon release of the stretched wiping element completes the assembly.
