ABSTRACT:
An adjustable arm load mechanism for an automotive windshield wiper is provided in which a load-adjusting linkage assembly is provided between the pivot shaft of the windshield wiper assembly and the wiper arm. The linkage assembly includes a cam member operative with a lever to effect variation of the spring load imposed upon the wiper arm in response to reversing reciprocal rotative movement of the pivot shaft so that wiper arm load is reduced at its extreme positions and increased in its intermediate positions.
