Abstract
A linkage mechanism for a safety attachment system in which a pair of traversing devices are engaged with an elongate safety line for sliding movement therealong past intermediate securing devices for the safety line. The traversing devices are coupled to the mechanism, and a lanyard connected to the mechanism applies a force thereto, when the lanyard is under tension, in a direction generally away from the safety line. The mechanism is adapted to cause relative movement of the traversing devices along the safety line when the force is applied thereto by the lanyard. An actuator, preferably using a spring, is provided in the mechanism to cause opposite relative movement of the traversing devices when the force is reduced.
