Problems solved by technology

However, known rebreather protection devices cannot be placed next to the user while driving a vehicle, since this entails the risk of breaking or damaging the restraint-guided breathing hose
That is to say, in general, it can be said that the known respirator devices are fixed in a defined wearing position and thus limit the flexibility of such respirator devices during use.

Embodiment Construction

[0070] Figures 1 to 4 A mask adapter 10 according to the invention is shown. The mask adapter is equipped with a mask coupling 20 in a connection capable of providing fluid communication to a respiratory mask 400 along a mask coupling axis 22 . The corresponding connection is in Figure 5 shown in . according to Figure 5 A fluidic connection to the breathing area 410 is provided inside the breathing mask 400 via the mask coupling interface 24 , which is designed in particular without rotation. This can be produced in a known manner, for example, by means of a bayonet closure, snap-in or by using a union nut.

[0071] According to the present invention, now the Figures 1 to 5 A mask adapter 10 of this type is equipped with a first hose coupling part 30 and a second hose coupling part 40 . Each of these hose couplings has a hose coupling axis 32 or 42 at Figures 1 to 5 are oriented vertically downwards and thus parallel to each other in an embodiment. The hose coupli...

Abstract

The invention relates to a mask adapter (10), for connecting two breathing tubes (210) of a closed-circuit respirator (300) to a breathing mask (400), includes a mask connection (20) for a fluid-communicating connection to a breathing area (410) of the breathing mask (400) and two tube connections (30, 40) with tube connection axes (32, 42) for a fluid-communicating connection to a breathing tube(210) each. The first tube connection (30) has an incoming air valve (34) and the second tube connection (40) has an outgoing air valve (44). The first tube connection axis (32) of the first tube connection (30) further forms an acute tube connection angle (alpha) with the second tube connection axis (42) of the second tube connection (40).

Description

technical field [0001] The invention relates to a mask adapter for connecting two breathing hoses of a rebreathing protection device to a breathing mask, a housing adapter for connecting breathing hoses to such a rebreathing protection device, with two breathing A hose and a breathing hose system of such a mask adapter and a method for adapting the breathing hose system to an alternative wearing position. Background technique [0002] It is known to use rebreather protection devices to protect users of such protection devices in hazardous surroundings. To this end, respirator devices are equipped with respiratory protection components, which are divided in particular into cooling components, cleaning components for expelling air from the user, and storage components for supplying oxygen or fresh air. In known solutions, the rebreather device is equipped with a breathing tube system which essentially has two breathing tubes. The breathing hose is on the one hand a first bre...
