A tension device for use with a self-retracting lifeline having a drum includes a lifeline and an elastic member. The lifeline has a retracting end, an intermediate portion, and a connecting end. The retracting end is operatively connected to the drum, and the connecting end is releasably connectable to a user. The elastic member interconnects the retracting end and the connecting end. The elastic member provides tension on the lifeline and prevents the drum from retracting the lifeline when the connecting end of the lifeline rebounds in an upward direction during a fall.
Dispositif de mise en tension utilisable avec un filin de sécurité à enroulement automatique et comprenant un barillet, la corde en question et un élément élastique. Le filin présente une extrémité reliée au barillet et une section intermédiaire, l'autre extrémité de sécurisation sert à sécuriser l'utilisateur à l'aide d'un dispositif d'accrochage pouvant être libéré. L'élément élastique assure la jonction entre l'extrémité rétractable et l'extrémité de sécurisation. Il imprime au filin la tension voulue et empêche le barillet d'enrouler la corde quand l'extrémité inférieure repart vers le haut au cours d'une chute.
