Abstract
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.
Claims20
An avalanche airbag, comprising
- a deployable first bag comprising a flexible, gas-permeable material, the first bag including a first inlet opening;
- and
- a deployable second bag disposed inside the first bag, the second bag including a second inlet opening, the second bag inflatable with gas and comprising a gas-tight material having an elasticity of at least 25%, wherein the first inlet opening at least partially encloses the second inlet opening.
A method for manufacturing an avalanche airbag having an outer bag and an inner bag, comprising:
- cutting at least two layers of a first material, each of the at least two layers having a peripheral edge;
- cutting at least two layers of a second material, each of the at least two layers having a peripheral edge;
- layering the at least two layers of the second material and securing the at least two layers together along the peripheral edges to form a gas-tight inner bag;
- disposing the inner bag between the at least two layers of the first material;
- and
- securing the at least two layers of the first material together along the peripheral edges to form an outer bag, wherein the inner bag is disposed inside of the outer bag.
An avalanche airbag, comprising
- a deployable first bag comprising a flexible, gas-permeable material, the first bag formed of at least two layers attached along respective peripheral edges of the at least two layers of the first bag, and
- a deployable second bag disposed inside the first bag, the second bag formed of at least two layers attached along respective peripheral edges of the at least two layers of the second bag in a gas-tight manner, the second bag inflatable with gas and comprising a gas-tight material having an elasticity of at least 25%, wherein the at least two layers of the second bag are disposed between the at least two layers of the first bag.
