Brain Bucket: (slang) A type of motorcycle helmet that enables motorcycle riders to be in compliance with the law where helmets are required, but offers inadequate protection, about that of a bicycle helmet - Urban Dictionary
University of Southern California (USC) Professor C.F. “Red” Lombard is credited with being the first to designed a motorcycle helmet to absorb the shock of an impact. IN 1953 Professor Lombard applied for a patent for his new invention which had two layers of padding. One layer inside which fit next to the wearers head and provided comfort, and the outer layer which absorbed and diffused the energy from an impact over the entire surface of the helmet. In 1967 South Carolina enacted legislation requiring all motorcyclists to wear helmets and thirteen years later 200 members of ABATE of South Carolina was successful in getting this law amended to apply to only those under 21.
Here's a bit of trivia. Half a decade before South Carolina implemented its motorcycle
helmet law, Australia became the world's first government to implement a mandatory motorcycle helmet law on January 1, 1961.
In 1974, the U.S. Department of Transportation (DOT) introduced their Federal MotorVehicleSafety Standard No. 218 (FMVSS 218) for Motorcycle Helmets. Since that date, helmets which meet the standard have been required to carry a DOT-approved sticker.
We doubt these helmets carry DOT-approved stickers but we like the creativity shown in their creation.
