Abstract: A device for adjusting the length of a flexible link according to the pulling force exerted on the link, the continuous link passing through the device between two substantially opposite input/output ends of the device. The device includes elements for producing at least one link loop whose extent can vary according to the pulling force, at least one return element tending to increase the extent of the loop up to a predefined maximum in the absence of pulling force on the link and which corresponds to a reduction of the apparent length of the link on which the device is placed, the pulling force of the link resulting in a reduction of the extent of the loop up to a predefined minimum and which corresponds to an elongation of the apparent length of the link on which the device is placed. Devices with S loop or omega loop are described together with a comfort unit for a strap harness.

Abstract: A cable (6a, 6b) winder (1) of a fall-arrest lifeline including a brake, the winder, which is intended to be attached to a holding point, includes a centrifugal brake in a housing, wherein the centrifugal brake is intended to slow the unwinding of the cable in the event of a fall, the cable winding onto a drum (2) from a first end attached to the shaft of the drum, the second end of the cable coming out of the winder and including an element for coupling to a load. The wound cable is furthermore secured to the drum at a predetermined distance from the first end by a removable securing element (5), the securing element ceasing to hold the cable on the drum when a tensile force greater than a release threshold is applied to the cable in order to release the predetermined cable distance.
