Abstract:
An energy absorbing connector for use in a fall arrest system, comprising:a metal strip having a first end, a second end, and an intermediate portion disposed therebetween, wherein a generally U-shaped cut in the first end separates the first end into a first tab and a second tab, and the first tab and the second tab are arranged to extend in opposite directions away from one another, and a separate hole is formed through each said tab, and a separate line of discontinuities in the strip extends from each end of the U-shaped cut to a respective position proximate the second end of the strip, and the second end of the strip and most of the intermediate portion of the strip are rolled up in a spiral fashion inside a remainder of the intermediate portion of the strip wherein the discontinuities are intermittently spaced, circular holes each having a first diameter and extending through the strip, each of said discontinuities terminates in a respective, relatively larger hole having a second diameter greater than said first diameter and extending though the strip proximate the second end, whereby when the first tab and the second tab are pulled in opposite directions with sufficient force, the connector tears and uncoils to absorb energy.
