ABSTRACT:
A protective helmet has its head harness constructed as a cooling gear. The harness forms a lining of the inside of a helmet shell and comprises two elastic sheets connected to each other by seams. The sheets are cut to double segments which are connected to each other at the top by an annular channel. The double segments are divided by longitudinal and transverse webs to form communicating cells. The space between the sheets is filled with a coolant which is introduced through annular channel in a liquid state. The double segments are connected to each other by a cross band through which the head harness is buttoned in, onto retaining buttons inside the helmet. To cool down, the harness can easily be unbuttoned and later put in place again in the same simple manner.
