Benefits of technology

[0019]The invention relates also to headsets designed with no specific visor and comprising a microfibre felt element making it possible to produce a friction resistance with a standard moving visor.
[0020]The invention also relates to visors that include a microfibre felt element making it possible to produce a friction resistance with a standard headset.

Problems solved by technology

The problem that arises for visored headsets is securing the visor in any position.
In practice, because of their weight and the severe usage stresses on board military aircraft, particularly the vibrations and temperature variations, the visors are difficult to secure.
The distance between the centre of gravity of the visor and its centre of gravity is also a cause that can tend to cause the visor to drop.
This system is difficult to adjust and varies with temperature.
It also has the drawback of sliding under vibration.
This system is also fairly hard to manoeuvre, so it may hamper the pilot in his mission.

Embodiment Construction

[0028]The invention is intended particularly for aircraft pilot headsets. The existing solutions, as described in FIG. 1, propose visor securing systems 13 based on mechanical means 11 and 12 that are difficult to manipulate, imprecise and not very effective in securing the visor when there are vibrations and changes of temperature.

[0029]The visored headsets for aircraft pilots generally comprise a rigid supporting headset and a moving visor that can perform a rotary movement about an axis positioned in the middle of the headset.

[0030]The invention is innovative in light of the existing solutions in that it proposes a solution for securing the visor 3 by microfibre felt elements 4. FIG. 2 shows an application mode in which the microfibre felt 4 is fixed to the visor 3. Preferably, the microfibre felt is glued to the central part of the visor in order for the friction force to be located level with the centre of gravity of the visor. In this way, the friction force does not need to b...

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.

Description

PRIORITY CLAIM[0001]This application claims priority to French Patent Application Number 08 05768, entitled Headset Including a System for Securing the Visor by Microfibres, filed on Oct. 17, 2008.FIELD OF THE INVENTION[0002]The field of the invention relates to headsets comprising at least one supporting shell and a visor.BACKGROUND OF THE INVENTION[0003]A headset for aircraft pilots, notably of fighter aeroplanes, is generally multifunction and is equipped with visors. Such a headset comprises a rigid supporting shell which generally surrounds the top, the back and the side portions of the wearer's skull. The headset generally includes visors through which the wearer of the headset can see his environment; these visors are more often than not retractable towards the top of the skull and provide protection for the face against various attacks (wind, dust, light or violent lighting, etc.). For night flights, a night vision system can also be inserted in front of the eyes of the wear...
