ABSTRACT:
The present invention is directed to a respiratory helmet. The helmet is designed to provide protection to a user's cranium area. The helmet also has a visor designed to provide protection to the user's face area, an air intake system, and a parallel elliptical rail system. The visor can be positioned on the helmet, in front of the user's face area, and any position in between. The area between the visor, when the visor is positioned in front of the user's face area and the face area is called the breathing zone. The visor has at least two wheels, a top side and a bottom side wherein the bottom side is positioned closer to the user's chin when the visor is positioned in front of the user's face. The air intake system has an intake unit that receives a gaseous medium from a gaseous medium supply system or the ambient air into the helmet, and the intake unit directs the gaseous medium toward the breathing zone. The parallel elliptical rail system allows the visor to move in an elliptical motion. Each rail receives at least one wheel of the visor, and is designed to decrease the accumulation of particulates on the rail.
