Abstract:
One embodiment of the present invention relates to an avalanche safety system including an inflatable chamber, activation system, inflation system, and a harness. 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 user from burial and provide flotation during an avalanche. The activation system is configured to receive a user-triggered action to activate the system. The inflation system may include an air intake, battery, fan, and internal airway channel. 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 harness may include hip straps, shoulder straps, internal compartments, etc.
