Four Mexican inventors are changing the direction of automotive windshield breaks. The team, with Ford global technologies in Michigan, has worked on a way to create a defined break for laminated windshields that directs a break outward. Originally they filed for a patent in July 2016, and were recently granted a patent for their design in June of this year.
A laminated windshield is made up of an outer and inner layer of glass, while plastic or a specially designed film, is commonly found between both layers and is known as the interlayer. The main benefit of interlayers is that it holds the inner and outer layers of glass together if the windshield breaks, shatters or becomes damaged in any way. Doing this can help reduce the amount of injury those inside of the vehicle may face. But what about if a person or persons want to safely escape the vehicle?
Their design incorporates a break line with an outward path, the main goal is to provide a way out of the vehicle from the inside in the event of an emergency. As the break line is directed outward, it resists breaking inward, according to the patent, which then allows it to provide higher levels of protection to vehicle occupants.
“While laminated glass provides a number of significant safety benefits, it should be appreciated that it can make it very difficult to escape from the interior of a motor vehicle when the doors of the vehicle have been rendered inoperable. …[our] laminated windshield incorporates a break line engineered to break outward toward the outer glass layer thereby allowing one to actually break the laminated windshield in order to provide an emergency escape route from the motor vehicle,” according to an excerpt from the patent.
