Abstract

An integral safety helmet is described in which a chin guard can be folded up. For the release of the chin guard, a central opening bar is provided on the front side of the chin guard. As a result, the locking mechanism can easily be opened by only one hand or by the thumb of the motorcyclist. In certain embodiments, the opening bar is designed as a two-armed lever having an upper arm and a lower lever arm. In this manner, the chin piece can be released in two different manners.
