CYLINDRICALLY ROLLED ENERGY ABSORBER FOR USE WITH A SELF-RETRACTING LIFELINE
A cylindrically rolled energy absorber (10) is provided to absorb the energy of a user's fall from a worksite and includes a strip (18) of bi-layered webbing defining two parallel rolls (22, 24) of webbing centered on a central axis (40), with the width of the strip (18) in each roll (22, 24) extending parallel to the central axis (40). The strip (18) includes two layers (42, 44) of webbing joined together over the length of the strip by tear-apart connections (46). Each end (36, 38) of the strip (18) has end portions (54, 56) of each the layers (42, 44) that are separated from each other. A first connector loop (26) extends from the roll (22) and is fixed to a first end portion (54, 56) from end (36) of the strip and to a second end portion (54, 56) from the other end (38) of the strip (18). A second connector loop (28) extends from the other roll (24) and is fixed to a third end portion (54, 56) from the end (36) of the strip (18) and to a fourth end portion (54, 56) from the other end (38) of the strip (18).
