Abstract

Combination head-protective helmet and communications system including a head-protective helmet and a flexible flame retardant earflap mounted removably to the helmet wherein a voice communications system including interconnected transceiver circuitry, microphone, speaker, battery and antenna is mounted on the earflap for quick and easy removal from the helmet with the earflap.

Claims

1. Combination head-protective helmet and communications system for providing head protection to the wearer of the helmet and generally hands-free voice communications between the wearer and others, comprising:

a head-protective helmet;

a flexible flame retardant earflap mounted removably to said helmet and including at least a portion extending downwardly therefrom to protect the ears of the wearer of the helmet from heat and flame, said earflap including an extension portion for being fastened under the chin of the wearer of said helmet;

a voice communications system including transceiver circuitry, antenna, throat microphone, battery and speaker collectively providing a complete system for voice communications between the wearer and others; and

said voice communications system completely and totally mounted on said earflap to position said throat microphone to receive voice communication from said wearer of said helmet, to position said speaker adjacent an ear of said wearer of said helmet to transmit voice communication to said wearer of said helmet and to position all of said antenna on said earflap to receive and transmit voice communication whereby removal of said earflap from said helmet also removes the entire voice communications system from said helmet.

2. The combination head-protective helmet and communication system according to claim 1 wherein said earflap includes an extension portion for being fastened under the chin of said wearer, and wherein said throat microphone is mounted on said extension portion to place said microphone adjacent the throat of and in voice communication with said wearer of said helmet.

3. The combination head-protective helmet according to claim 1 wherein said earflap is provided with an inner pocket, and a housing receiving said transceiver circuitry, said battery and said speaker and wherein said housing resides in said pocket.

4. The combination head-protective helmet according to claim 1 wherein said earflap is provided with an outer pocket, and a housing receiving said transceiver circuitry, said battery and said speaker, and wherein said housing resides in said pocket.

5. The combination head-protective helmet according to claim 4 wherein said outer pocket is made of flexible flame retardant material and is provided with a flap for being snap fitted to said pocket to close said pocket and for being unsnapped from said pocket to open said pocket for entry and removal of said transceiver to and from said pocket.

6. The combination head-protective helmet according to claim 1 wherein said earflap includes a plurality of flexible layers secured to each other and said antenna is sandwiched between said layers.
