2.6.4 Open Face Helmet
The open face helmet (Fig. 2.6) covers the back of the skull but does not have the
lower chin bar like the full face helmet, and the face shield is optional. In many
open face helmets, visors are used to reduce glare. Although an open face helmet is
similar to a full face helmet in rear protection, it hardly provides facial protection
even from non-crash events. An open face helmet, where it does not have a visor,
limits protection to the rider from insects, dust particles or even wind to the face and
eyes, resulting in injury or inconvenience. Face shields fitted to open face helmets
protect the upper part of the face and the eyes,
2.6.5 Half Helmet
The half helmet (Fig. 2.7) is similar to the open face helmet but has a raised back.
The half helmet provides the least coverage of the five helmets. Unlike open face
and full face helmets, half helmets are subject to shifting and sometimes come off
the rider’s head during an accident.
2.7 Bicycle Helmets
A bicycle helmet as shown in Fig. 2.8 is designed to protect the head of a bicyclist
from impact [22], and this is its primary function. A bicycle helmet should be very

activity which raises the body temperature, especially of the head. As a result, there
