A fall-protection apparatus comprising at least one connector that comprises a resonant-frequency-shifting inductive sensing unit that is configured to detect whether the connector appears to be connected to a first item and is further configured to detect whether the connector appears to be connected to a second, different item.

Fall-protection apparatus with multimodal inductive sensing

A fall-protection safety harness including left and right shoulder straps and a waist strap, and a dorsal plate mounted on the left and right shoulder straps at a dorsal crossing point. A dorsal brace for use with such a harness, the brace comprising a self-locking fastener at the upper end of the dorsal brace. The fastener is fastenable, and self-locking, to the dorsal plate, and a lower end of the dorsal brace is connectable to the waist strap. Methods of equipping a safety harness with the dorsal brace.

Safety harness with self-locking dorsal brace

A safety harness including first and second shoulder straps and a waist strap and a rigid dorsal force-transfer member with an upper end that is removably connected to the first and second shoulder straps at a dorsal crossing point of the first and second shoulder straps and with a lower end that is removably connected to a dorsal portion of the waist strap. Methods of removably equipping a safety harness with a rigid dorsal force-transfer member, and of removing a rigid dorsal force-transfer member from a safety harness.

Safety harness with removable rigid dorsal force-transfer member

The present disclosure provides a fall protection system. The fall protection system includes a lanyard defining a first end, a second end, and a third end. The lanyard includes a one-piece webbing including a first portion including the first end and a second portion including the second end. The second portion is continuous with the first portion at the third end. The lanyard further includes a main connected portion connecting the first portion to the second portion proximal to the third end. The fall protection system further includes a truss extending between the first portion and the second portion and connected to each of the first portion and the second portion. The truss is disposed proximal to the main connected portion, such that the main connected portion is disposed between the third end and the truss.

Fall protection system

A buckle assembly and a harness including the buckle assembly. The buckle assembly includes a male buckle and a female buckle removably coupled to the male buckle. The male buckle includes a catch and a first adjustment member extending from the catch. The first adjustment member defines a plurality of first slots therethrough, such that each first slot is configured to movably receive a first webbing therethrough. The female buckle includes a main body and a second adjustment member extending from the main body. The main body is configured to at least partially receive the catch therein. The second adjustment member defines a plurality of second slots therethrough, such that each second slot is configured to movably receive a second webbing therethrough.

Buckle assembly and harness comprising the same

A buckle with a first pawl that is biased by a pair of magnets that are oriented in opposition to each other to provide a repelling force, and with a second pawl that is biased by another pair of magnets that are oriented in opposition to each other to provide a repelling force.
