Is a bike helmet patented?

Short answer: specific designs of a bike helmet have been patented many times, but "a bike helmet" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a bike helmet been patented?” but “has my combination of features been described before?” Vehicle accessories and travel gear differ in how they attach, fold, lock or secure items.
