IN-MOLD PROTECTIVE HELMET HAVING INTEGRATED VENTILATION SYSTEM

摘要

The present invention provides a lightweight protective helmet having an improved ventilation system therein. The protective helmet comprises an outer shell and an inner liner that are joined together to form a shell/liner composite. The ventilation system interacts with one or more ventilation ports in the protective helmet to control the flow of ambient air in and out of the interior of the protective helmet. The ventilation system may be integrated or encased within the shell/liner composite, or it may be adapted to be used on the exterior of the helmet. In addition, the ventilation system may include one of several types of interchangeable insert members to allow active or passive control of ambient air into the interior of the helmet.

主权项

1. An in-mold protective helmet comprising: an outer shell; an inner liner comprised of impact absorbing material having suitable impact attenuation properties to protect a wearer of said protective helmet, said inner liner joined to said outer shell using an in-mold process to form a shell/liner composite; a plurality of ventilation ports positioned within said protective helmet, said ventilation ports providing an access for ambient air to enter and exit an interior portion of said protective helmet; a ventilation system integrally formed with said protective helmet and interacting with at least one of said plurality of ventilation ports to control flow of said ambient air into and out of said interior portion of said protective helmet, said ventilation system comprising: an upper portion; a lower portion; a vent space defined by the formation of said upper portion with said lower portion; and a vent shield contained within said vent space, said vent shield capable of displacing within said vent space in relation to said at least one ventilation port.
