The airbag device includes an airbag and a gas generator. The gas generator includes a body containing inflation gas and sealed with an unsealable lid, and a discharge portion that includes a housing, an outlet that is formed in the housing and allows outflow of gas to the airbag when the body is unsealed, a piercing pin for unsealing the lid, a spring for moving the pin, a retaining member that retains the spring, and a sliding mechanism that shifts the retaining member to a release position. The sliding mechanism includes a drive source and a connecting member that shifts the retaining member to the release position by a driving force of the drive source. The piercing pin, spring, lid and a portion of the retaining member retaining the spring are housed in the housing. The drive source and connecting member are partitioned from a gas channel inside the housing.

A ski resort safety system and method. A ski resort comprises a piste (300). The ski resort safety system comprises: an anti-collision suit (1), wherein the anti-collision suit (1) is worn by a skier and comprises an inflation device (100) and a control device (200), the inflation device (100) is configured to inflate the anti-collision suit (1) under the control of the control device (200), and the control device (200) is configured to detect the condition of the skier, and when the skier encounters a danger, trigger the inflation device (100) to inflate the anti-collision suit (1), and is configured to transmit a danger signal when detecting the dangerous condition of the skier; and relay devices (301), wherein the relay devices (301) are arranged along the piste (300) at a certain interval so as to receive the danger signal, and transmit a trigger signal to other skiers (2′) on the piste (300). By triggering the anti-collision suits (1) of other skiers (2′) located below an out-of-control skier (2), the out-of-control skier (2) per se can be protected, and other skiers (2′) are also effectively prevented from being accidently damaged.

A method for alerting a user of a wearable airbag system. The method includes the steps of ensuring that the airbag system is active, checking the current location of the airbag system, calling a server storing a plurality of locations, each location being associated with an increased risk for an accident, and if the current location of the airbag system is close to a stored location, further performing a step of alerting the user.

A belt will be worn by the individual. Attached to this belt will be a plurality of rolled up legs and gas canisters. Electro-viscous fluid is contained in the harness that will activate the gas canisters; the advantage of using electro-viscous fluid is that it will cause a rapid inflation of the legs with minimal power. On the front of the belt will be an activation device that will send a small electrical charge to engage the gas-powered canisters to quickly inflate the plurality of legs and prevent the person from falling.

The present invention relates to a wearable protection device (10 comprising:—a protective helmet (12), provided with at least one first inflatable chamber (14); said at least one first inflatable chamber (14) being suitable for moving between a rest condition, wherein it is in a deflated status, and an operating condition, wherein it is in an inflated status;—a wearable element (16) comprising an inflator unit (18) and an activation system (20); the activation system (20) being designed to trigger the inflator unit (18) if a danger situation for the user of the wearable protection device (10) is identified. According to the invention, the wearable element (16) comprises at least one second inflatable chamber (26) suitable for moving between a rest condition, wherein it is in a deflated status, and an operating condition, wherein it is in an inflated status. The inflator unit (18) is connected to said at least one first inflatable chamber (14) and/or to said at least one second inflatable chamber (26). The inflator unit (18) is designed to inflate said at least one first inflatable chamber (14) and/or said at least one second inflatable chamber (26) so as to move said at least one first inflatable chamber (14) and/or said at least one second inflatable chamber (26) in the operating condition when a danger situation for the user of the wearable protection device (10) is identified by the activation system (20).

The present invention relates to a wearable protection device (10) comprising at least one inflatable member (20) suitable for moving between a rest configuration, wherein it is in a deflated status, and an active configuration, wherein it is in an inflated status, the at least one inflatable member (20) comprising at least one elongated portion (22; 22a, 22b) which departs from a connecting body (26); the at least one elongated portion (22; 22a, 22b) being in fluid communication with the connecting body (26). According to the invention at least one part of said at least one elongated portion (22; 22a, 22b) is enwrapped by at least one constraint (24) which is designed to limit the expansion of said at least one elongated portion (22; 22a, 22b) when the inflatable member (20) moves in the active configuration.
