Windshield wiper blades are a small but important part of a car. They often go unnoticed and sometimes even neglected. But windshield wipers are a very important part of not only a car, but any vehicle, as they are installed on all motor vehicles, from cars to trains, planes, and boats. They are also usually required by law, why do you ask? Because windshield wipers or flat blades help make driving safer by removing water and dirt from the windshield that can block the driver’s view.

Flat wiper blades consist of a swing arm that pivots from one end. The side of the blade that touches the glass has a long rubber attached, so when the arm swings back and forth, water and debris are pushed away, ensuring the driver’s view is clear and unobstructed . The main objective of this mechanism is security; so the windshield is always free of anything that might block the driver’s view.

Also, windshield wipers are often coupled to a windshield washer or sprayer. When activated, the sprinkler would throw water onto the windshield and then the blades would sway. The purpose of this is that the driver can clean the windshield anytime, anywhere.

Mary Anderson is credited with inventing the windshield wiper swing arm because she was able to patent it in the United States in 1903. However, it was JH Apjohn who was able to devise the method of having two brushes go up and down on a piece of windshield glass. same year. Whatever the case, windshield wipers became standard on all American cars 13 years after Mary Anderson patented it. And in 1919 William Folberth was able to invent the first automatic windshield wiper and the patent was granted in 1922. Then Robert Kearns introduced in 1969 the feature of having an adjustable delay between wipes. Citroen then introduced the first rain sensitive windshield wipers in 1970 and it was used on their SM model. The wipers would move once and check to see if the glass was wet or dry. If it were dry, the motor would draw a higher current and a lag would be created. If the glass were wet, the motor would draw a lower current and oscillate faster with less delay. Since 2006, rain-sensing and rain-sensing windshield wipers have been common among Cadillacs and are available upon request from other auto dealers such as Honda, Toyota, Chrysler, Jeep, Mercedes, and others.

Flat blade windshield wipers have come a long way since 1903. Today, they are not only automatic, but also have a variety of uses. Some cars are equipped with smaller windshield wipers on the headlights to ensure adequate and modified lighting. Other models, such as minivans, sport utility vehicles or SUVs, and pickup trucks, have rear window wipers to make sure your rear view is clear of mud and dirt as well.
