<p>A windshield wiper drive link (22) is pivoted indirectly to a crank arm (20) through an intermediate toggle member (28) and a pair of oppositely-directed beams (40,42) cut into the side walls (36,38) of the drive link stamping. Under excess load, one or the other of the beams (40,42) will buckle in compression, allowing the drive link (22) to in effect change length, thereby yielding to avoid overload. <IMAGE></p> |
