An airbag compartment enclosure assembly is disclosed, including a compartment containing an uninflated airbag and a closure device fixed proximate an opening of the compartment. The closure device has an open position allowing expansion of the airbag through the opening and a closed position retaining the uninflated airbag. The closure device includes a first flap extending from a first edge of the opening and a second flap extending from a second, opposing edge of the opening. The first and second flaps are folded over one another in the closed position.

Knee ascenders that include modular replaceable components are described. The knee ascender has an elastic piece that provides pulling force to move the knee ascender upwards and is not secured to any of the other components of the knee ascender, making replacing the elastic piece that is subject to frequent wear and tear convenient. Additionally, the length of the load bearing member, the elastic piece, as well as the guiding piece of the elastic bearing member can be adjustable, making the knee ascender suites climber's many different needs.

Avalanches often trap people under the snow. Although nearly all avalanche victims survive the initial avalanche, asphyxiation will occur after about fifteen minutes if rescuers do not know where to dig to uncover avalanche victims. Drones can include unique hardware and software that enables them to search for avalanche victims and mark the locations of avalanche victims to quickly and accurately notify rescuers where to dig through the snow to save avalanche victims from asphyxiation.

A device for releasably retaining a carabiner, said device includes: an elongate body with a jaw member hingedly attached at a first position thereto, said jaw member being movable towards and away from the elongate body in a first plane; a first projecting member and a second projecting member extending outwardly from a first side of the elongate body and away from the first plane; a third projecting member extending outwardly from a first side of the jaw member and away from the first plane, wherein the first projecting member and the second projecting member are configured to receive a spine of a carabiner inserted therebetween and whereupon third projecting member is configured to urge a gate of the carabiner toward the spine of the carabiner.

A device for warning about the absence of belaying of a climber includes an enclosure intended to be fastened to a harness. A pressure sensor is designed to measure a barometric pressure. A detector, intended to be fastened to a link, is configured to detect a movement of the link within a range of positive inclines with respect to a horizontal reference plane. The detector is also configured to output a detection signal comprising a first state, indicating that the link is within the range of positive inclines, and a second state, indicating that the link is outside the range of positive inclines. A microprocessor is configured to compute a variation in the barometric pressure measured by the pressure sensor, and send a warning signal as soon as the variation in the barometric pressure exceeds a predetermined threshold and the detection signal is in the second state.

The knot protector protects ropes and knots from ledges, rocks, railings, edges, walls, cliffs, and other surfaces that may cause the fibers of the rope to be gradually abraded or destroyed. The knot protector includes a sleeve formed from an upper portion, a lower portion, and a shoulder portion. The upper portion defines a first opening while the lower portion defines a second opening. The diameter of the first opening is smaller or less than that of the second opening. The sleeve is formed from a deformable, continuous web and has exterior and interior layers. The sleeve also contains visual safety indicators along the base of the lower portion to provide visibility. The exterior and interior layers are made from durable material to provide the rope with ample protection from abrasion.
