The invention relates to a carrying device, in particular a backpack (10), for an avalanche airbag system (12), which includes an airbag (14) and a filling device (16) for introducing at least one medium into the airbag (14). The airbag (14) brought into a stowage position is received in a container (18) if the avalanche airbag system (12) is coupled to the carrying device. The container (18) comprises a closure element (34). After opening the closure element (34), the container (18) can be brought from a closed position into an open position. The carrying device includes at least one spring element, which is tensioned if the container (18) is brought into the closed position, and by means of which bringing the container (18) from the closed position into the open position can be effected. The closure element (34) can be opened by actuating an actuating device (28), by means of which the filling device (16) can be brought into a triggered state. In the triggered state, the filling device (16) introduces the at least one medium into the airbag (14).

The invention relates to an avalanche airbag system (10) comprising an airbag (14) and a filling device (20) for introducing ambient air into the airbag (14). The filling device (20) comprises a fan (16) with an electric motor (18), a first electric energy storage (22, 40) for providing electric energy to the electric motor (18), a second electric energy storage (24) and a control device (26) for actuating the electric motor (18). By means of the control device (26) depending on at least one parameter both a supplying of the electric motor (18) with electric energy originating from both energy storages (22, 40, 24) as well as with electric energy originating from only one of the two energy storages (22, 40, 24) can be effected. Moreover, the invention relates to a backpack comprising such an avalanche airbag system (10) and a method for operating such an avalanche airbag system (10).

A snow burial survival mask has an exhaust tube connected to a headgear. An intake port of the exhaust tube is positioned adjacent to a breathing portion of the headgear in order to intake exhaled carbon dioxide (CO2)-rich air. An air pump connected to the exhaust tube pump the exhaled air from the intake port to an exhaust port away from the user's face, extending survival time in a snow burial situation. At least one burial detection sensor such as a motion sensor, light sensor and/or CO2 sensor is configured to activate the air pump based on detection of a burial event.

A device, method and system improve the breathable air quality of the environment in the region of a specific part of a body, such as around the mouth and nose area of a person buried in an avalanche. The device includes at least one inlet, at least one pump, at least one power resource, a controller, and at least one outlet. An inlet of the pump is constructed to act as a chamber. A first end of the chamber is connected to the inlet and a second end of the chamber is an opening towards the outside of the device. When the pump is activated, the pump will provide a vacuum in the chamber and suck air from the surroundings into the pump through the second end of the chamber and the chamber.
