ABSTRACT:
An aerodynamically streamlined bicycle racing helmet has a molded, plastic helmet body having an exterior shape which is streamlined to provide minimum resistance to frontal airflow. Downwardly extending ribs are formed in the interior surface to define channels for airflow to pass through the interior of the helmet. The rearward portions of the ribs of the helmet are extended downward beneath the lower edge of the helmet to insure that such airflow is not blocked by the back of the user. A pair of strap loops are also attached to the front and upper rear portions of the helmet and form a chin strap which is used to retain the helmet snugly in place upon the head of the user. The attachment points of the straps are specifically selected so that the sides of the strap engage the user's head and prevent tilting of the helmet when it is in use. The helmet may also be provided with a stretch cap with an airflow opening, which allows selection of exterior color, striping or other ornamentation.
