Headset Including a System for Securing the Visor by Microfibres

Abstract

The invention relates to headsets comprising at least a supporting shell and a moving visor that can be displaced between two extreme positions. The headset includes a system for securing the visor in any position between the two extreme positions by friction between the visor and the supporting shell, the friction being produced by at least one microfibre felt element. The invention applies to the field of headsets in general for users of motorized craft such as in aeronautics and automobiles for example.

1 . Headset comprising at least a supporting shell and a moving visor that can be displaced between two extreme positions, and a system for securing the visor in any position between the two extreme positions by friction between the visor and the supporting shell, the friction being provided by at least one microfibre felt element. 
   
   
       2 . Headset according to  claim 1 , wherein securing system comprises at least two microfibre felt elements, a first element fixed to the supporting headset and a second element fixed to the visor. 
   
   
       3 . Headset according to  claim 2 , wherein when the two felt elements are in friction, the orientation of the microfibres of the first felt element is not parallel to the orientation of the microfibres of the second felt element. 
   
   
       4 . Headset according to  claim 3 , wherein the microfibres of the felt elements are oriented so that the friction force is greater in a first direction of displacement of the visor than in a second direction of displacement of said visor. 
   
   
       5 . Headset according to  claim 1 , wherein the kinematics of the visor on the headset are variable to vary the friction force on displacement of the visor from one extreme position to another extreme position. 
   
   
       6 . Headset according to  claim 1 , wherein the microfibre felt has a variable surface area to vary the friction force on displacement of the visor from one extreme position to another extreme position. 
   
   
       7 . Headset according to  claim 1 , comprising at least one microfibre felt element fixed only to the visor. 
   
   
       8 . Headset according to  claim 1 , comprising at least one microfibre felt element fixed only to the supporting headset. 
   
   
       9 . Headset, comprising a microfibre felt element for producing a friction resistance with a standard moving visor. 
   
   
       10 . Headset visor, comprising a microfibre felt element for producing a friction resistance with a standard headset.
