Abstract

A helmet comprises a headshell, visor and a harness within which the head of the user is engagable. An auxiliary electrically operated service is provided, such as a lamp or air supply, operated by a switch actuated as the helmet is engaged or disengaged from the user's head. When the service is an air supply, the switch operates a fan motor which draws air into the helmet through a filter.
