ABSTRACT:
The present invention is directed to an airbag system that a user can deploy to reduce the chances of being buried in an avalanche or if buried, likely being buried near the surface, thereby improving the user's chances of surviving the experience. In one embodiment, the airbag system is comprised of an inflatable balloon, a pressure gas cylinder for holding a pressurized gas that is used in inflating the balloon, a valve that can be placed in a closed state to retain a pressurized gas in the pressure gas cylinder or an open state in which pressurized gas is released from the pressure gas cylinder. The system further comprises an ejector that operates to use pressurized gas received from the pressure gas cylinder and ambient air to inflate the balloon. Also part of the system is a flow restrictor that is located to receive pressurized gas from the pressure gas cylinder before the ejector receives the gas. A harness supports the noted elements of the system adjacent to an individual's body.
