Abstract
A windshield wiper drive link is pivoted indirectly to a crank arm through an intermediate toggle member and a pair of oppositely directed beams cut into the side walls of the drive link stamping. Under excess load, one or the other of the beams will buckle in compression, allowing the drive link to in effect change length, thereby yielding to avoid overload.
