  • Patent number: 5571221
    Abstract: The present invention relates to an automobile windshield wiper protection device for raising the windshield wiper to be spaced from the windshield, thereby reducing degradation of the rubber wiper blade which are normally in contact with the windshield heated by the sun, and preventing dirts from accumulating between the wiper blade and the windshield. The present invention includes a housing to be disposed on the windshield wiper. The housing accommodates a DC motor for actuating a driving mechanism. The driving mechanism includes a telescopic pusher rod capable of effecting a linear motion, and the pusher rod urges against the windshield for raising the wiper blade. A double pole double throw switch is incorporated in the circuit, and is electrically connected to the ignition system of the vehicle, such that the wiper blade is lowered or raised in response to the switching on and off of the ignition system.
