Abstract
A unitized cowl and wiper arm assembly includes a blow molded plastic shell structure and two wiper arms of the integral type. At two locations, the shell is reformed so as to create an area of increased stiffness that includes a pair of spaced, overhanging interior flanges. This allows the journal portion of the arms to pass through the shell and be pivoted thereto between the spaced interior flanges. Thereafter, the arm is rigidly and securely supported. The leakproof interior of the shell may also be used for a fluid reservoir.
