CA 2535847

A preferred embodiment self-retracting lifeline (100) includes a centrifugal clutch assembly (121) having a pawl (128) and a spring (131). The pawl (128) and the spring (131), which do not require any fixed attachment to any other component of the device, are held in place and pivotable within a plate (143). The plate (143) is rotatable within a cavity (120) of a brake hub (118) including teeth (141) extending into the cavity (120). When a centrifugal force is applied, the pawl (128) compresses the spring (131) and moves away from the plate (143) to engage the teeth (141) thereby activating a brake assembly within the self-retracting lifeline (100).

Dans un mode de réalisation préféré de l'invention, un ensemble filin de sécurité auto-rétractable (100) comprend un ensemble embrayage centrifuge (121) présentant un cliquet (128) et un ressort (131). Le cliquet (128) et le ressort (131), qui ne nécessitent pas de raccordement fixe à un autre composant du dispositif, sont maintenus en place et peuvent pivoter à l'intérieur d'une plaque (143). Cette dernière (143) peut tourner dans une cavité (120) du moyeu de frein (118) comprenant des dents (141) qui s'étendent à l'intérieur de la cavité (120). Lorsqu'une force centrifuge est appliquée, le cliquet (128) comprime le ressort (131) et s'écarte de la plaque (143) pour venir en contact avec les dents (141) et activer ainsi un ensemble frein dans l'ensemble filin de sécurité auto-rétractable (100).
