(54) Systems and methods for inflatable avalanche protection with reinflation


(57) One embodiment of the present invention relates to an avalanche safety system (100) having an inflatable chamber (140), activation system, inflation system (160), and a harness (120). The inflatable chamber (140) 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 activation system also includes a reinflation algorithm configured to automatically reactivate the inflation system after a period of time to maintain the inflated state of the inflatable chamber. The inflation system may include an air intake (180), battery (166), fan (164), and internal airway channel (168). The inflation system is configured to transmit ambient air into the inflatable chamber.
