Abstract
A wiper arm and method for manufacturing a wiper arm provides a body having a first end connectible to and supportable by a drive shaft for imparting oscillatory rotary movement and a second end connectible to and supporting a wiper blade. A torsional region of the body is capable of toggle action and is located between the first and second ends of the body. The toggle action is defined by two stable positions, a primary position and a secondary position, lying spaced at opposite sides of an unstable range of movement, where one of the two stable positions exerts downward pressure on the wiper blade connectible to the body for engagement against a windscreen to be wiped. The torsional region is defined by first and second torsional members initially formed in a relaxed state. Each torsional member has a free end cantilevered outwardly from the first end of the body and spaced from one another. Each torsional member is subsequently flexed into a flexed state such that the free ends engage one another. The free ends are connected with respect to one another by any suitable attachment method or fastener when in the flexed state.
