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 sub surface terrestrial disaster safety device comprising a housing constructed from impact-resistant materials, a pressurized colored gas cylinder containing a neon-based mixture, an oxygen cylinder, an olfactory signal cylinder, and a micro controller. The micro controller includes sensors to distinguish between normal activities and disaster conditions, initiating a triggering mechanism upon detection. The triggering mechanism activates a permeation system controlling gas flow, creating a distinct surface mark for enhanced visibility to rescuers, while simultaneously providing emergency oxygen to the user. An alternative embodiment includes a communication module emitting a rescue signal with GPS coordinates. The device represents an advancement in safety technology, combining visibility enhancement, oxygen supply, and rescue signaling in a lightweight, durable design for individuals in disaster-prone environments.

The invention relates to an inflatable bag (60) with an inflation device (20), wherein the inflation device (20) comprises a first opening (22) adapted to allow the intake of a gas and a second opening (9) connected to the inflatable bag (60). The inflation device (20) further comprises a control (6) and an actuable valve (8) with an inlet opening (13) and an outlet opening (14), wherein the actuable valve (8) is controlled by the control (6) such as to open and close the actuable valve (8). The inlet of the actuable valve (8) is connected to the inflatable bag (60) such that it, when opened, creates a fluid communication channel between the inflatable bag (60) and the outlet (14) of the actuable valve (8) such as to allow deflation of the inflatable bag (60).
