US Patent 9492711 Systems and methods for modular inflatable avalanche protection

One embodiment of the present invention relates to an avalanche safety system including an inflatable chamber, activation system, inflation system, harness, and a container. The inflatable chamber is a three-dimensionally, partially enclosed region having an inflated state and a compressed state. The inflated state may form a particular three dimensional shape configured to protect the use from impact and/or provide flotation during an avalanche. The inflation system is configured to transmit ambient air into the inflatable chamber. The harness may be a backpack that enables a user to transport the system while engaging in activities that may be exposed to avalanche risk. The container is releasably coupled to the harness including a coupled and a separate state. The container independently includes a container chamber that is selectively enclosable by a container opening. The releasable coupling between the container and the harness may include a periphery zipper type coupling.
