Abstract
A protective helmet that includes a cap, a protective padding, possibly a comfort padding, and a retaining system. According to the invention, the cap has a visual impact indicator whose state changes when the cap is subject to an impact exceeding a predetermined threshold. For example, the indicator is formed by a capillary tube sealed at both ends enclosing a drop of colored liquid trapped between two gas bubbles. The invention applies to any type of helmet, for the practice of a sport, for motorcycling, for professional use, or as a safety helmet.
