Abstract: STRAP ADJUSTMENT DEVICE AND HELMET COMPRISING ONE SUCH ADJUSTMENT DEVICE An adjustment device is configured to adjust a position of a body along a strap. The adjustment device comprises a strap and a body. The body has a first face and a second face. The body defines a running path. The strap passes through the body along the running path. The body defines a first inlet/outlet slot and a second inlet/outlet slot terminating the running path. The body defines a first friction slot and a second friction slot that connect the first face to the second face. The first inlet/outlet slot and second inlet/outlet slot are separated by the first friction slot and second friction slot in a longitudinal direction of the strap.

Abstract: A roping harness comprises a belt and leg loops joined by a leg loop connection. A connector keeps the belt and the pair of leg loops together, the latter each passing through a connection ring of the connector. The belt and leg loop connection are movable with respect to one another and with respect to the body. The connector has a body, a rotation shaft and a first D-ring mounted rotatable with respect to the body around the rotation shaft. The first D-ring pivots around an axis of rotation parallel to a direction passing through the connection ring. The first D-ring is connected to the body by means of the rotation shaft fixedly mounted on the body.

Abstract: A camming clamping device comprises a head provided with an anchor point. A cam is installed rotatable around at least one shaft between a retracted position and an extended position. A spring is functionally coupled to the cam to bias the at least one cam to the extended position. An annular end is mechanically coupled to the head. A wire element connects the head and the annular end. The wire element is in the form of a ring. The ring is folded into a U-shape with two legs joined by a central portion. The two legs are fixed to the anchor point. Four strands of the wire element connect the head and the annular end. An actuating system has a trigger installed slidingly and configured to selectively engage the retracted position.

Abstract: A rope clamping device including a body with an attachment device to a user and a first through hole receiving a rope strand. A deformable channel is formed by a plurality of links mounted consecutively behind one another between a first link and a last link. The links are attached consecutively two by two by swivel shafts and mounted swivelling around swivel axis to modify the cross-section of the channel. Each link includes two primary contact surfaces designed to be in contact with the rope strand, the two primary contact surfaces facing one another in a direction perpendicular to the swivel axis. The two primary contact surfaces of each link are pivotally movable with respect to one another.

Abstract: A belay device comprises a casing with an opening for a rope loop. A roller is inserted movable in the casing and mounted idle. The roller is mounted movable between first, second and third roller positions. A rotation clamp either allows free rotation of the roller or disables one rotation direction of the roller depending on the position of the roller in the casing. The rotation clamp allows free rotation when the roller is in the first roller position and disables one rotation direction of the roller when the roller is in the second and third roller position. A spring biases the roller to the first roller position and transforms a force on the roller into a position of the roller in the casing.

Abstract: An energy absorber has a textile element comprising two substrates connected to one another by breaking links and resistant links, the textile element being wound. A container receives the textile element. The container defines a first opening for a first end and a second opening for a second end of the textile element. The resistant link connects a portion of the two substrates and maintains the connection in response to a first stress applied between the first end and the second end. The breaking links break and absorb energy in response to a first stress between the first end and the second end of the textile element. The container is non-openable and defines an access hole opening out facing the centre of the textile element in wound state.

Abstract: A camming clamping device comprises a head with a cam installed swivelling around a pivot shaft between retracted and extended positions. An annular end is mechanically coupled to the head. A rod of variable length connects the head with an annular end designed to receive a carabiner. A wire element made from textile material passes through the rod to connect the head and the annular end. A trigger is installed slidingly to selectively engage the retracted position of the cam. An adjustment device of the length of the rod defines at least a distance between the head and the annular end that is greater than a threshold distance to stretch the wire element and compress the rod in the first direction.
