A trauma relief strap assembly has a relief strap with a first strap and a second strap connected to the first strap at two or more connection points along a major longitudinal length of the relief strap. The relief strap further has one or more steps formed as a closed loop between two adjacent connection points. Each step has a longitudinal portion extending in a direction of the major longitudinal length of the relief strap and defined by one of the first strap and the second strap, and a lateral portion protruding laterally from the longitudinal portion and defined by the other of the first strap and the second strap.

There is provided a suspension trauma relief strap assembly for use in a fall protection harness comprising: a first housing integrally mounted within one side of the fall protection harness and configured to hold a strap, where the strap has a first end and a second end, and where the first end is operably connected to the first housing and the second end includes a connector; and a connection mechanism disposed on a second side of the fall protection harness, where the connection mechanism is configured to connect with the connector to form a connection assembly. There is also provided fall protection harnesses including these suspension trauma relief strap assemblies.

A body harness system includes a body harness having a first portion for providing resting position to a user. The body harness includes a plurality of belts with offset buckles connected to the body of the first portion, for supporting body of the user. A first pair of shoulder straps are connected at a first end and an undercarriage support is connected at a second end of the first portion. An abdominal support is connected to the undercarriage support via abdominal support connection straps. The undercarriage support runs from the second end of the first portion to the abdominal support, for supporting the user's groin area. The body harness system includes an elastic cord support system connected to one or more attachment rings, for controlling at least one of initial bodyweight offset, amount of bodyweight resistance, and maximum allowable downward stop for each user.

A fall detection/fall indicator device (20) that automatically senses when a user (14) of fall protection equipment, such as a fall harness (10), has experienced an arrested fall, the fall harness (10) having an electrical circuit (45) that is a closed circuit (46) in a first state and an open circuit (48) in a second state after an arrested fall, and an alert device (62) that is automatically responsive to the open circuit (48) to emit an alert/alarm to other personnel that an arrested fall has been experienced.

A descender device, typically for use in a fall arrest system, that enables a suspended body to be lowered, and includes a descent line and a release element to be actuated by a person. The release element is arranged in a restraint configuration to inhibit the descent line from being deployed and in a release configuration to permit the descent line to be deployed. A restraint arrangement is arranged prior to deployment of the descent line, to clamp or pinch a length of flexible line thereby to inhibit deployment of the descent line, the restraint arrangement being reconfigurable upon release of the release element to permit the descent line to be deployed.

A safety harness for vertically lifting of a user is provided. The safety harness includes an upper body harness and a lower body harness which may be positioned on liners within a coat and pants of the user, respectively. The upper body harness and lower body harness attach together to function as a Class III harness enabling lifting of a user in a vertical orientation by virtue of the harness geometry. The lower body harness alone serves as a Class II harness and the upper body harness alone serves as a drag line. The harness is particularly suited to be integrated with firefighting turnout gear for ready donning with the turnout gear.

A connection arrangement for use with a wearable body harness has a first connector having a body with a first portion of a locking mechanism and a second connector having a body with a second portion of the locking mechanism. The first portion of the locking mechanism has a tab connected to the body of the first connector and a slot having a first portion extending through the body of the first connector and a second portion extending through the tab. The second portion of the locking mechanism has a tongue configured for being received through the first portion of the slot, and an intermediate connecting element having a first end connected to the body of the second connector and a second end connected to the tongue. The second end of the intermediate connecting element is offset from the body of the second connector.

A fall protection system includes an elevation mechanism including a base end and an elevated end, and that is configured to permit a user to scale the elevation mechanism. The first channel is disposed at a first side of the elevation mechanism and extends between the base end and the elevated end, and is configured to anchor a first shuttle to the elevation mechanism and permit the first shuttle to transition between the base end and the elevated end of the elevation mechanism. The second channel is disposed at a second side of the elevation mechanism and extends between the base end and the elevated end, and is configured to anchor a second shuttle to the elevation mechanism and permit the second shuttle to transition between the base end and the elevated end of the elevation mechanism.

A fall arrest system includes a line retraction device having a safety line, an energy absorber configured for connecting to a terminal end of the safety line, and a harness configured for connecting to the energy absorber such that the energy absorber is disposed between the terminal end of the safety line and the harness. The safety line is selected to have a predetermined mean breaking force with a first standard deviation, and the energy absorber is selected to have a predetermined mean deployment force with a second standard deviation. The mean breaking force of the safety line and the mean deployment force of the energy absorber overlap over an overlapping region of the first and second standard deviation. A ratio of an overlap mean force of the overlapping region to an overlap standard deviation of the overlapping region is less than or equal to 6.

A fall detection/fall indicator device (20) that automatically senses when a user (14) of fall protection equipment, such as a fall harness (10), has experienced an arrested fall, the fall harness (10) having an electrical circuit (45) that is a closed circuit (46) in a first state and an open circuit (48) in a second state after an arrested fall, and an alert device (62) that is automatically responsive to the open circuit (48) to emit an alert/alarm to other personnel that an arrested fall has been experienced.
