Abstract: A winder comprises a housing defining a cavity and a spool installed rotatable in the cavity. Rotation of the spool in a first or second rotation direction winds the wire element around the spool or unwinds the wire element. The wire element exits from the spool passing through a through opening of the housing. The spool arranges a channel receiving the wire element and that has a first end with at least one spiral turn. The first end of the channel is terminated by a wall. In a threshold position representative of maximum unwinding of the wire element, the wire element is wedged between the wall and a face of the housing bounding the through opening to form a stop preventing rotation of the spool in the unwinding direction beyond the threshold position.

Abstract: A headlamp with a headband is presented. The headlamp includes: a headband element to receive a lamp body, and a passing hole or vertical conduit for the sliding passage of a tightening elastic link and an attachment clip to make a horizontal sliding connection with an electrically conductive cord, a rear part with a support to hold an electric battery and a locking lever; an electrical conductor cord having two radii of curvature so as to form a “Z”; a movable clip positioned at the first radius of curvature to ensure sliding of said electrically conductive cord with the upper part of the tightening elastic link; a second movable clip positioned at the level of the second radius of curvature to allow the electrically conductive cord to slide with the lower part of said tightening elastic link.

Abstract: A headlamp with—a headband; a light source located at the front of the headband is presented. The headlamp has a load balancing device with two strands. The first strand has a first end (A) and a second end (B) respectively attached on one left front fixing point and one left rear fixing point of said headband. The second strand has a first end (A?) and a second end (B?) respectively attached on one right front fixing point and one right rear fixing point of said headband. There is an element wherein the first and second strands are thread up so as to bring closer the two strands at one common point C.
