Problems solved by technology

[0003] Due to a certain variability in the boundary conditions of the human body, the veneer cannot always be placed on the user's face with an exact fit in some cases
This can lead to oxygen leakage and discomfort when wearing the mask
Additionally, the oxygen regulator can cause neck tension as the oxygen regulator tends to pull the user's head forward due to its weight
Additionally, the user's field of vision may be limited by the oxygen regulator
Finally, if the microphone is located near the oxygen regulator, the speech intelligibility of the user's microphone may be affected by the oxygen flow

Embodiment Construction

[0031] figure 1 A mask system 2 is shown, which is worn on the head 4 of the user. The earphone part 6 contained therein has two ear cups 8 which are carried on a headband 10 . The headband 10 is elastic and may have a spacing between the ear cups 8 in the unworn state which is smaller than that of the user's ears. Therefore, when the earphone part 6 is worn, the headband may apply slight stress to the ear, so that the headband 10 is easily fixed on the head 4 .

[0032] Furthermore, the mask system 2 has an oxygen mask part 12 which has an exemplary oxygen mask 14 arranged pivotably on the headband 10 . In the shown state, the oxygen mask 14 is in the idle state and rests flush against the headgear 10 . Furthermore, the visor system 2 has a spectacle part 16 with an exemplary visor 18 arranged pivotably on the headband 10 . The goggles 18 are here also in the rest position and lie flush against the headband 10 .

[0033] The oxygen mask 14 and the goggles 18 are pivotal...

Abstract

Provided is a mask system (2) for an aircrew of an aircraft. The mask system has: a headphone part (6) having two earmuffs (8) and an elastic headband (10) carrying the earmuffs (8); an oxygen mask portion (12) having an oxygen mask (14) pivotably arranged on the headband (10); and an eyeglass part (16) having a goggle (18) pivotably arranged on the headband (10). The oxygen mask portion(12) is designed to allow the oxygen mask (14) to move into a use position and a rest position when the headband (10) is worn on the head (4). The oxygen mask (14) covers the mouth (28) and the nose (26) of theuser in the use position and is at least partially placed above a head band (10) worn on the head (4) in the rest position, and wherein the eyeglass part (16) is designed to allow the goggle (18) topivot into a use position and into a rest position when the headband (10) is worn on the head (4), wherein the goggles (18) cover the eyes (30) of the user in the use position and are at least partially arranged above a headband (10) worn on the head (4) in the rest position.

Description

technical field [0001] The invention relates to a mask system for the crew of an aircraft and to an aircraft with such a mask system. Background technique [0002] To protect the crew against oxygen deprivation and against smoke or toxic gases in decompression situations, face masks are commonly used, which cover the entire face and can be donned quickly. This mask is also called "Full Face Quick Donning Mask" (FFQDM). Such masks are kept in an easily accessible position during flight and are grabbed, donned and used for breathing in an emergency. These masks have a face covering that covers the nose and mouth. The mask also has glasses for smoke protection. Arranged on the veneer is an oxygen regulator which generally has three different operating modes. In the first mode of operation, oxygen is directed to the user together with ambient air. In the second mode of operation, pure oxygen is directed to the user; and in the third mode, oxygen is directed to the user at o...
