  • Patent number: 8356691
    Abstract: An energy absorber for use in a personal fall arresting system wherein a pair of webbing are held together by tear away binder elements which are arranged to rupture under controlled conditions to prevent failure of the absorber when experiencing high load conditions.
    Type: Grant
    Filed: August 18, 2009
    Date of Patent: January 22, 2013
    Assignee: Sturges Manufacturing Co., Inc.

  • Patent number: 7815013
    Abstract: An energy absorber for use in a personal fall arresting system. The absorber contains upper and lower webbings which are each two ply members. The back ply of the upper webbing is mounted adjacent to the face ply of the lower webbing with said webbing being of about equal length and width. Exterior tear elements run back and forth sinusoidally between attachment points on the face ply of the upper webbing and the back ply of the lower webbing. Interior tear elements run back and forth sinusoidally between attachment points on the back ply of the upper webbing and the top ply of the lower webbing.

  • Publication number: 20080179136
    Abstract: An energy absorber for minimizing elongation upon deployment when used in a personal fall arresting system. The energy absorber contains at least two tear-away members in which each tear-away member includes upper and lower webbings that are each two ply members. The back ply of the upper webbing is mounted adjacent to the face ply of the lower webbing with this webbing being of about equal length and width. Exterior tear elements run back and forth sinusoidally between attachment points on the face ply of the upper webbing and the back ply of the lower webbing. Interior tear elements run back and forth sinusoidally between attachment points on the back ply of the upper webbing and the top ply of the lower webbing. The absorber, including the at least two tear-away members, can be made from a continuous strip of material wherein the tensile strength of each of the tear elements of each tear-away member is less than that of the attachment points.

  • Patent number: 5377386
    Abstract: A quick release disconnect for a harness comprising an attached pivotable collar that is pulled through gravitational force from a lock position of upward rotation into a normal release position of downward rotation. The pivotable collar in its lock position of upward rotation engages a yoke on a snaphook. A tang secures the pivotable collar in its lock position to the yoke. A flexible quick-release means detaches the from the pivotable collar such that the pivotable collar returns to its normal release position and the yoke is automatically disengaged from the pivotable collar.
