Abstract
An energy-absorbing unit with a first end bearing a modular connector that is disconnectably connectable to a complementary modular connector of a cable of a self-retracting lifeline, and with a second end bearing a fastener that is fastenable to a dorsal connection point of a fall-protection harness. Uses of such units in combination with self-retracting lifelines and fall-protection harnesses.
Claims14
A self-retracting lifeline fall-protection apparatus comprising:
- a base unit comprising a housing and a reel that is rotatably connected to the housing;
- a load-bearing cable with a first end that is attached to the reel of the base unit of the self-retracting lifeline and with a second end that is attached to a first modular connector;
- and,
- an energy-absorbing unit comprising an energy absorber with a first end to which is attached a second modular connector that is disconnectably connected to the first modular connector and with a second, opposing end to which is attached a fastener that is configured to be fastened to a dorsal connection point of a fall-protection harness.
