Patent Images
1. A powered air-purifying respirator helmet system, comprising:
- a helmet including a lens;
a photovoltaic power source mounted on the helmet;
a trunk-worn blower separate from the helmet, the trunk-worn blower comprising a fan and a rechargeable battery operably connected to power the fan;
a flexible air-electrical conductor interconnecting the trunk-worn blower and the helmet to simultaneously supply both pressurizing air to the helmet and electrical energy generated by the photovoltaic power source on the helmet to the trunk-worn blower.

Abstract
A powered air-purifying respirator helmet system includes a helmet having a lens. A photovoltaic power source is mounted on the helmet. A trunk-worn blower is separate from the helmet. The trunk-worn blower includes a fan and a rechargeable battery operably connected to power the fan. A flexible air-electrical conductor interconnects the trunk-worn blower and the helmet to simultaneously supply both pressurizing air to the helmet and electrical energy generated by the photovoltaic power source on the helmet to the trunk-worn blower.
