Abstract
The use of a fall arrest lanyard that provides fall arrest forces at least two primary levels is disclosed. One example provides a lanyard with a pair of shock absorbers of different capacities in series. Other examples use a single shock absorber that provides at least two distinct levels of arrest force. Varying the strength of the attachment area that is to be separated to provide the arrest force and by varying the amount of area being separated at one time varies the levels of arrest force.
