Abstract

The environmental system for motorsports helmets includes a helmet and backpack containing various components of the system. The helmet includes an inlet and air passages for forced air ventilation, a tube conducting drinking water from a helmet inlet to the mouth of the helmet wearer, and a radio communications headset. The helmet is a full-face helmet having an openable transparent face shield and visor formed with the face shield as a unit. A backpack is provided with the helmet, the backpack containing a motor driven fan to supply air to the helmet. The air is filtered through an external filter on the pack, before entering the fan and ventilation system. A water tank is also included in the backpack, allowing the helmet wearer to draw water from the supply. A conventional communications transceiver is also provided with the backpack, the transceiver connecting to the headset within the helmet.

Dependent claims

An environmental system for a motorsports helmet, comprising:

a protective helmet having a selectively openable face shield, the face shield substantially sealing the helmet when closed;
at least one ventilation duct disposed within the helmet;
a water supply tube disposed within the helmet;
a communications radio headset and microphone disposed within the helmet;
a backpack having an air inlet;
an air filter disposed at the air inlet of the backpack;
a ventilation fan disposed within the backpack, the ventilation fan selectively drawing air through the air filter;
an air delivery line extending from the backpack, the air delivery line being removably connected to the helmet, the air delivery line selectively delivering filtered air to the at least one ventilation duct of the helmet when the ventilation fan is actuated;
a water container disposed within the backpack;
a water delivery line extending from the water container of the backpack, the water delivery line being removably connected to the helmet, the water delivery line selectively delivering water to the helmet;
a communications transceiver disposed with the backpack;
and
a communications cable extending from the transceiver, the cable being removably connected to the helmet, the communications cable selectively connecting the transceiver of the backpack to the headset and microphone of the helmet.

10 more elements

An environmental system for a motorsports helmet, comprising:

a protective helmet;
a visor pivotally attached to the helmet, the visor being selectively raised and lowered;
a face shield immovably affixed to the visor, the face shield being adapted for sealing the helmet when the visor is lowered;
a ventilation fan remotely situated from the helmet, the ventilation fan communicating with the helmet;
a water container remotely situated from the helmet, the water container communicating with the helmet;
and
a communications transceiver remotely situated from the helmet, the communications transceiver communicating with the helmet.

4 more elements

An environmental system for a motorsports helmet, comprising:

a protective helmet having a selectively openable and closable face shield, the face shield being adapted for sealing the helmet when closed;
a ventilation fan remotely situated from the helmet, the ventilation fan communicating with the helmet;
a ventilation fan electrical power supply disposed with and selectively operating the ventilation fan;
a water container remotely situated from the helmet, the water container communicating with the helmet;
a communications radio remotely situated from the helmet, the communications radio communicating with the helmet;
and
a communications radio electrical power supply disposed with and selectively operating the radio, the communications radio electrical power supply being separate and independent from the ventilation fan electrical power supply.
