Abstract: A fall-protection device for use with a safety harness of a user includes a housing configured to be connected to the safety harness. The fall-protection device further includes a lifeline extending from the housing. The lifeline includes a lifeline end distal to the housing and configured to be coupled to an anchor. The lifeline is retractable or extendable relative to the housing. The lifeline is extendable relative to the housing from a retracted state in which a length of the lifeline extending out of the housing is minimum. The fall-protection device further includes a flexible cover extending from the housing and coupled to the housing and the lifeline. The flexible cover at least partially encloses the lifeline. The flexible cover contracts or expands as the lifeline retracts or extends, respectively, relative to the housing.

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.
