Title
(EN) PROTECTIVE HEADWEAR WITH AIRFLOW
(FR) CASQUE DE PROTECTION AVEC CIRCULATION D'AIR
Abstract
(EN)
In one aspect, a protective headwear is provided and includes an outer shell (24), a first shell duct (113) coupled to the outer shell and including a first exhaust port, and a second shell duct (115) coupled to the outer shell and spaced apart from the first shell duct. The second shell duct includes a second exhaust port. The protective headwear also includes a manifold (112) positioned externally of the outer shell and configured to divert airflow into at least a first potion of airflow and a second portion of airflow. The manifold includes a first diversion (128) member coupled to and in fluid communication with the first shell duct to provide the first portion of airflow to the first shell duct, and a second diversion member (132) coupled to and in fluid communication with the second shell duct to provide the second portion of airflow to the second shell duct.
(FR)
Selon un aspect, l'invention concerne un casque de protection comprenant une coque extérieure (24) , un premier conduit de coque (113) raccordé à la coque extérieure et comprenant un premier orifice d'évacuation, et un second conduit de coque (115) raccordé à la coque extérieure et situé à une certaine distance du premier conduit de coque. Le second conduit de coque comprend un second orifice d'évacuation. Le casque de protection comprend également un collecteur (112), positionné à l'extérieur de la coque extérieure et conçu pour dévier le flux d'air en au moins une première partie de flux d'air et une seconde partie de flux d'air. Le collecteur comprend un premier élément (128) de déviation, raccordé au premier conduit de coque et en communication fluidique avec lui, qui va servir à amener la première partie du flux d'air jusqu'au premier conduit de coque, et un second élément de déviation (132), raccordé au second conduit de coque et en communication fluidique avec lui, qui va servir à amener la seconde partie du flux d'air jusqu'au second conduit de coque.
