Abstract

A windshield wiper assembly for use in a motor vehicle. An electric motor is operatively connected to and powered by an on-board electrical supply provided by the vehicle. The motor forms a part of a housing mounted within an engine compartment of the vehicle at a location remote from the vehicles windshield. A driving wheel and linkage member convert a rotary output of the motor into a translating and reciprocating driving force. A drive mechanism is mounted proximate a lower edge of the windshield with a first wiper arm pivotally securing to the drive mechanism at a first location and a second wiper arm likewise pivotally securing to the drive mechanism at a second location. The drive mechanism provides a gear and belt arrangement for actuating the first and second wiper arms in a synchronous manner. One or more elongated and internally hollowed sleeves extend between the housing and the drive mechanism. Each sleeve encloses a flexible and incompressible cable securing to the motor and drive housing at a first end and to the drive mechanism at a second end. The cable is acted upon by the driving wheel and linkage of the housing and imparts the reciprocating and translating driving force to the gear and belt arrangement of the drive mechanism to operate the wiper arms and blades and so as to permit mounting of the motor and housing within the engine compartment at a location remote from the firewall separating the occupant compartment.
