A rescue device for assisting in removing an individual from a confined space comprises a sheet comprising a high-density polyethylene having first and second ends and a projection extending laterally outward from the first end and has a top edge, a bottom edge, a projection edge, and a securing element. The sheet has first and second through apertures inset from the second end and aligned with the projection. The sheet is rollable between an undeployed position wherein the sheet has a reduced diameter and a deployed position wherein the projection is passed through the first and second through apertures and partially secured by the securing element. In the deployed position, the securing element may abut the sheet and retain the device in the deployed position.

The present invention is a personal flotation device comprising an inflatable bladder, a harness configured to be worn on the body of the user comprising a body belt and at least two vertical straps on the front of the harness configured to extend upward over the user's shoulders and connect to the back of the harness, the inflatable bladder attached to the front of the harness and slidably attached to the body belt and the at least two vertical straps, an inflation mechanism configured to inflate the inflatable bladder, and the inflatable bladder configured to expand vertically and horizontally across the user's chest when it is inflated.

The present invention relates to an avalanche protection device that includes an avalanche protection backpack with at least one inflatable buoyant airbag and a breathing system with a breathing housing. The breathing housing connects a one-way inhalation valve to an inhalation tube, and at least one intake port, and at least one ambient air suction zone. It also connects a one-way exhalation valve to an exhalation tube and a CO.sub.2 exhalation region. A mouthpiece is provided on the breathing housing, which is able to be automatically pulled tightly onto the mouth of an avalanche victim by means of a facial airbag, by actuating a trigger handle. The invention additionally relates to a method for using such an avalanche protection device.

A portable device for inflating at least one envelope includes an inlet for surrounding air (1), at least one nonreturn valve, at least one compressed gas inlet (2), at least one intake chamber (3), at least one connection, such as an acceleration cone (5), with a longitudinal median symmetry axis (X, X), arranged in the extension of at least one intake chamber (3), and connected to at least one inflatable envelope, and an intermediate chamber connecting at least one compressed gas inlet (2) to at least one intake chamber (3). The intermediate chamber and the at least one intake chamber (3) are separated by a wall arranged transversely to the axis (X, X) and connected by at least one orifice located in the transverse wall (8).

The present invention relates to a perforator for breaking a closing member at a gas outlet of a gas bottle to allow a gas to flow out. The perforator includes a cylindrical housing having three openings, namely, a first opening at a first end portion, a second opening at a second end portion which is opposite to the first end portion, and a third opening formed in a circumferential wall portion, an ignition device being fixed at the first opening, the second opening to be connected to the gas bottle and the third opening serving as a gas discharge portion, and when a pressure created by actuation of the ignition device is received, the first piston moving in an axial direction, and the second piston moving towards the second opening by receiving the movement of the first piston.

A portable safety device (100) for inflating multiple envelopes includes at least one inlet for surrounding air (1), at least one inflation system, at least one enriched air or gas zone, at least one nonreturn valve (2), at least one connector (3) connected to the at least one inflatable envelope (4). The device also includes at least one separation wall (8), which compartmentalizes at least the end of at the connector (3) opening into at least two substantially hermetically independent inflatable envelopes (4).
