Patent ID: 7171717

Claim:
A windshield wiper and spoiler combination comprising: a windshield wiper having a blade, said blade having a front edge; a spoiler having a folded plate connected with said front edge of said blade, both ends of said spoiler being each inwardly folded for a length to form a slightly erected flap, said spoiler having an inclined surface which is formed with two ventilation holes in shuttle shape at two ends of said inclined surface, each ventilation hole having a shallow slot round the periphery thereof; a first rectangular opening formed between an intermediate portion of said blade and said spoiler; a second rectangular opening formed between a first end of said blade and said spoiler, said spoiler provided with a first plate protrusion adjacent said second rectangular opening; a third rectangular opening formed between a second end of said blade and said spoiler, said spoiler provided with a second plate protrusion adjacent said third rectangular opening; whereby wind force hitting against said spoiler will fall at a place behind said shallow slot on a peripheral of said ventilation holes to create a disturbance for helping stabilize operation of said wiper, and wind force hitting a bottom of said wiper will escape through said ventilation holes upwardly thereby forming a compression force to avoid said wiper from being lifted by said wind force collected at said bottom of said wiper, and said inclined surface will help said wind force escaping through said ventilation holes to further create a compression force for said wiper thereby preventing said wiper from being lifted up for helping achieve a more smooth operation of said wiper.
