Google has patented the creation of an innovative ‘sticky’ car bonnet, which is designed to prevent a person from being flung off the bonnet and on to the road in the event of a collision.
The system targets this ‘secondary stage’ of a pedestrian impact, where most fatalities occur, suggesting it could drastically reduce the number of pedestrian deaths if it were to be successfully integrated into vehicles.
The patent has been published on the USPTO (United States Patent and Trademark Office), revealing its technical details. It shows that a car’s bonnet is covered in an adhesive layer, finished with an outer shell that can be painted to match the rest of the body. The outer shell prevents debris from sticking to the adhesive, but in the event of a pedestrian hitting the surface, this outer shell breaks to allow the person to bind to the adhesive below.
