Abstract

A force responsive, variable length push rod for connecting the motor and windshield blade of a windshield wiper unit. The variable response push rod includes a pair of members connected at one end to the motor and windshield blades respectfully and overlapped at the other end. Each member includes a plurality of lobes extending to the area between the opposed members and an elastomer adheres to the lobes and fills space between the plurality of lobes to form push rod. Interdigitized lobes and elastomer define the force characteristics of the push rod.
