| 1. Monitoring apparatus for a safety helmet, comprising:
an array of force-responsive sensors mounted in the helmet for sensing contact forces between an inner periphery of the helmet
and a user's head;
a control module mounted in the helmet and coupled to the force responsive sensors for determining if the helmet properly
or improperly fits the user's head based on the sensed contact forces; and
a warning indicator activated by the control module when improper helmet fit is determined;
wherein said array of force-responsive sensors sense contact forces between the inner periphery of the helmet and a left side,
a right side, a top and a back of the user's head.
