Patent abstract
An improved retention system for a protective helmet comprises slide/coupling mechanisms on opposite sides of the helmet shell, and a movable element at the rear of the helmet. Fastening of the chinstrap secures the helmet in the downward direction and tightens the movable element against the nape of the neck, thereby securing the helmet in the area of the occipital lobe.
