2 ~ 3 COMMUNIC~TTON WIRING STRUCTURE IN HELMET
BACKGROUND O~ THE INVENTION
FIELn OF THE INVENTION
The field of the present invention is communication wiring structures in the helmet, in which the earphone and the microphone are mounted to the cap body which is compirsed of the shell and the shock absorbing liner fitted to the inner surface of the shell.
DESCRIPTION OF THE PRIOR ART
Such a helmet is designed to enable a communication with another person through the microphone and the earphones, when a driver or a passanger on a motorcycle or a racing car puts on the helmet.
In the prior art helmet, a communication wire connected to the Microphone and the earphones is disposed in an inner surface of the cap body and retained by clips or the like.
In such a prior art wiring structure, the clips or the like are used to retain the communication wire, resulting in problems that a wiring operation is troublesome, that the communication wire may interfere when the user puts on or off the cap body, and that the wiring may be dislocated.
SUMM~RY O~ THE INVENTION
Accordingly, it is an obiect of the present invention to provide a com~unicat;on wiring structure in a~helmet, wherein the communication wire can be properly disposed in the cap body without use of clips or the like, and a dislocation of the communication wire can be prevented 2~6~63 even when pu-tting on or off the helmet.
To achieve the above object, according to the present invention to provide a communication wiring structure in a helmet in which an earphone and a microphone are mounted to a cap body which is compirsed of a shell and a shock absorbing liner fitted to an inner surface of the shell, wherein the structure comprises a wiring groove provided in that surface of the shock absorbing liner which is opposed to the shell, and a communication wire connected to the earphone and the microphone, the communication wire being contained in the wiring groove.
With the above arrangement of the present invention, the communication wire can be properly retained in the cap bodY without use of any cLips or the like, and moreover, there is no portion exposed to ..~,i an inner surface of the cap body and therefore, when putting on or off the helmet, it is possible to prevent the communication wire from becoming an obstacle or being di s 1 oca ted.
