The first D-ring is connected to the body by means of the rotation shaft fixedly mounted on the body.

Abstract: A headband for a protection helmet comprises a strip forming at least a part of a ring around a user's head. An adjustment device adjusts a circumference of the ring. The end of the strip is fixed to an attachment point that is movable with respect to the body of the adjustment device.

The transmission comprises a flexible transmission shaft configured to transfer a rotary torque applied on the rotary actuator into a rotary torque applied on the adjustment device to move the attachment point and modify the circumference of the ring. A protection helmet comprises such headband.

Abstract: A headband comprises a strip forming a part of a ring around a user’s head. An adjustment device adjusts a circumference of the ring by moving one end of the strip that is fixed to an attachment point movable with respect to the body. A rotary actuator is functionally connected to the adjustment device by means of a transmission so that rotation of the rotary actuator results in movement of the attachment point. The adjustment device comprises a threaded section and a nut. The nut and threaded section forming a helical link, rotation of the rotary actuator results in movement of the nut along the threaded section. The nut or threaded section moves along a longitudinal axis of the threaded section and supports the attachment point. A helmet comprises such headband.

Abstract: The device for adjusting and clamping a strap comprises superposed first and second rings to define a slot for the strap to pass through. The second ring presses on the first ring. The slot for the strap to pass through is bounded by an outer edge of the second ring and an inner edge) of the first ring. The two rings are movable with respect to one another so that the slot for the strap to pass through is of variable thickness. A bottom surface of the first ring opposite the top surface of the first ring has a textured area provided with several salient elements designed to form an increased friction area between the strap and the bottom surface of the first ring. The textured area is separated from the outer edge of the second ring by the slot for the strap to pass through.

Abstract: A rope comprises a core extending along a longitudinal axis and a sheath surrounding the core, the sheath extending along the longitudinal axis. A strap at least partially surrounds the sheath, the strap being separated from the core by the sheath. At least one thread passes several times through the strap, sheath and core to form several links fixedly securing the strap on the core and sheath. The links pass through a central section of the core, the central section corresponding to a circular section representing less than 50% of the cross-section of the core. The links are angularly offset from one another when observed along the longitudinal axis.

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 adjustment system is configured to adjust the length of a first strap. The adjustment system comprises a ring defining a first through hole in a first direction. A pin is fitted movable with respect to the ring. The pin partially obstructs the ring in the first direction so as to divide the first through hole into a second through hole and a third through hole separated from the second through hole by the pin. The adjustment system comprises a tab at least partially blanking off the first through hole in the first direction. The tab is arranged at a distance from the pin to define a space for the first strap to pass between the pin and the tab.

Abstract: The tandem pulley comprises a pair of sheaves mounted in line between first and second flanges. A gate is fitted rotating with respect to the first flange between closed and open positions. The gate comes into contact with the second flange in the closed position to close a housing. The clamp is movable in rotation on the gate between a locking position locking the gate in the closed position and an unlocking position. The clamp has a prong pressing on the first flange and the gate in the locking position. The clamp has an actuating area separated from the first flange by the gate. Rotation of the actuating area from the locking position to the unlocking position corresponds to a movement of the actuating area away from the second flange. Rotation of the actuating area results in pivoting of the prong.

Abstract: The carabiner comprises a C-shaped body (1) and a gate (2) fitted movable between an open position and a closed position. The gate (2) is fitted rotatable with respect to the body (1). The gate (2) defines a cavity (2a) receiving a spring (4). A pusher (5) presses on the body (1). The spring (4) installed in the cavity (2a) of the gate (2) presses on the gate (2) and on the pusher (5) to bias the gate (2) to the closed position. The spring (4) is a coil spring extending along the longitudinal axis of the cavity (2a). The spring (4) and pusher (5) are fixedly mounted on one another to form a monolithic assembly.

Abstract: A headlamp with a light source, a power module to generate power for the light source from control information or a control signal, a control module for adjusting the power generated by the light source. The control module has a light sensor for sensing light from the environment of the lamp holder. The control module generates control information according to the information generated by the light sensor. The control module has an accelerometer to provide at regular intervals data representative of an acceleration of the headlamp along at least one horizontal axis and one vertical axis. The control module stores and processes accelerometry data. The control module includes a LUT lookup table stored in memory. The parameter read from the LUT lookup table is used in conjunction with information generated by the light sensor to determine the light output control information or signal.

A second flange and a sheave are mounted rotatable around the first shaft with respect to the first flange. A rod is fixed to the first flange and mounted movable between a first position and a second position with a first movement. In the first position, the rod engages with the second flange to keep the second flange in the first position. In the second position, the rod allows rotation of the second flange. A blanking plate is fixed on the second flange and mounted movable between a first position and a second position with a second movement different from the first movement. The blanking plate partially covers the rod to prevent movement of the rod from the first position to the second position.
