  • Patent number: 11633634
    Abstract: A fall arrest system includes a line retraction device having a safety line, an energy absorber configured for connecting to a terminal end of the safety line, and a harness configured for connecting to the energy absorber such that the energy absorber is disposed between the terminal end of the safety line and the harness. The safety line is selected to have a predetermined mean breaking force with a first standard deviation, and the energy absorber is selected to have a predetermined mean deployment force with a second standard deviation. The mean breaking force of the safety line and the mean deployment force of the energy absorber overlap over an overlapping region of the first and second standard deviation. A ratio of an overlap mean force of the overlapping region to an overlap standard deviation of the overlapping region is less than or equal to 6.
