In more than 82 per cent of fatal car crashes with pedestrians in the U.S. between 1996 and 2007, the point of impact was some part of the front end of a vehicle.
In many of these collisions the front bumper will ram into a person’s lower legs, sending them away from the vehicle, while the upper body and head fall into the hood or windshield.
When collisions occur at lower speeds, pedestrian will remain on the hood, but when the velocity is dialed up, the impact becomes much more extreme and can lead to severe injuries.
According to a 2007 study on pedestrian injuries, at higher speeds people are often flipped upside down before landing on the hood, somersaulted onto the windshield or roof and, at the most extreme, cause them to “pass fully over the vehicle” before they slide, roll or bounce before coming to a rest.
The severe injuries resulting from these “secondary impacts” is what Google is hoping to mitigate with a new patent for an “eggshell-like” hood that would break upon impactRead More »from Google patent for sticky car hood aims to prevent severe injuries
