An avalanche airbag system with an inflatable airbag and a filling unit for filling the airbag with a fluid has at least one pressure vessel containing a fluid, and a trigger mechanism for opening the at least one pressure vessel as required.

A clutch assembly for a climbing rope including a tether component pivotally supporting a plate, the plate in turn supporting a pair of pivotal clutch members defining a first pinch point of the rope. A carabiner pivotally attachable to the tether component through an aligning support aperture in the plate. A lever is pivotally attached to the tether component and slidably attached to the plate which permits at least one of sliding displacement or pivoting of the plate relative to the tether component to establish each of a sliding configuration of the rope relative to the clutch members during either of a normal ascent or normal descent condition, as well as a locked configuration of the clutch members against the rope to establish a free-fall preventing condition.

A connection device comprises a connector forming a ring with an open position and a closed position. A handle is fixed to the connector and has two extensions receiving a user's hands. The handle defines a tube extending in a first direction and a through hole arranged to pass through the tube perpendicularly to the first direction. A first end of a wire member forms a loop fixed to the connector in the tube. The second end of the wire member is fixed to the user. The connector passes through the through hole and the loop to fix the handle and the wire member to the connector.

Disclosed are embodiments of rope designs and making and manufacturing of such ropes. In some embodiments, a rope comprises a set of first rope cores, each first rope core of the set of first rope cores comprising a first material; a set of second rope cores, each second rope core of the set of second rope cores comprising a second material, the second material being different from the first material; and a rope sheath configured to encompass the set of first rope cores and the second rope core. In some cases, the rope sheath is braided from a plurality of rope sheath strands.

Disclosed is a belay device for climbing including an automatic winder including a pulley and a rope. The device includes an electric motor configured so as to apply a torque to the pulley and an encoder coupled to the pulley. The motor is controlled using the encoder according to the rotation of the pulley so as to modulate the torque applied to the pulley according to at least: —an assistance mode in which the torque applied by the servomotor to the pulley drives a pulling of the rope which assists the climber in his climb; and —a fall mode in which the torque applied by the servomotor to the pulley blocks a fall of the climber or slows it to a speed less than 3 m/s. Also disclosed is a climbing game system with virtual or augmented reality using such a belaying device.

A quad anchor can have a first attachment loop and a second attachment loop. Each of the first and second attachment loops are operable to connect to an anchor point. The quad anchor can also include an intermediate loop disposed between the first attachment loop and the second attachment loop and joined to the first attachment loop and the second attachment loop. The intermediate loop is operable to connect to a load to be supported by the quad anchor.
