An apparatus that stores air for underwater use in an emergency. The device includes an air and water impermeable reservoir having reinforcing ribs each with a hole to allow air flow within the reservoir. The reservoir is filled with air through a mouthpiece via an air pump. The mouthpiece is fluidly connected to the reservoir with an air transfer channel to allow a user to take several breaths of air when underwater.

The invention relates to an avalanche airbag (2), comprising a deployable outer bag (12), consisting of a flexible, gas-permeable material, and a deployable inner bag (13), consisting of a gas-tight elastic material and inflatable with gas, whereby the inner bag (13) is arranged inside the outer bag (12). The material of the inner bag (13) has an elasticity of at least 25%. The avalanche airbag (2) facilitates rapid deployment after activation over the entire temperature range as well as a small pack volume with a low total weight. Furthermore, the invention relates to a method for manufacturing an avalanche airbag (2) and an avalanche airbag system.

A rescue device for assisting in removing an individual from a confined space comprises a sheet comprising a high-density polyethylene having first and second ends and a projection extending laterally outward from the first end and has a top edge, a bottom edge, a projection edge, and a securing element. The sheet has first and second through apertures inset from the second end and aligned with the projection. The sheet is rollable between an undeployed position wherein the sheet has a reduced diameter and a deployed position wherein the projection is passed through the first and second through apertures and partially secured by the securing element. In the deployed position, the securing element may abut the sheet and retain the device in the deployed position.

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).
