A hip belt (2) is connected to the interface member at a first region (50) of the interface member. A first shoulder belt (16) and a second shoulder belt (18) are connected to the interface member at the first region and at a second region (52) of the interface member. The hip belt and/or the first and second shoulder belts comprise at least one first moulded heat resistant plastic material.

A carabiner for carrying equipment is disclosed. The carabiner includes a hook assembly including a generally C-shaped body having an opening which is closed by an openable gate. It further includes a mounting assembly, which includes a mounting boss to which the body is releasably connected, and one or more fasteners to connect the mounting boss to a base component. The mounting boss may include a bore through which the body passes, the body being a close fit in the bore, such that the body can pivot respect to the boss about an axis of the bore. Control components may be provided that serve to resist movement of the body within the bore. The carabiner may be installed in a harness, by connecting the base to a component of the harness for example by passing a fastener through a hole in the component.

Various embodiments are directed to relief apparatuses and methods of using the same. In various embodiments, a relief apparatus may comprise a housing comprising an interior housing portion configured to store a relief step device therein, and an activation assembly configured to facilitate an automated deployment of the relief step device from within the interior housing portion in response to a fall occurrence, wherein the automated deployment of the at least a portion of the relief step device is based at least in part on a load force acting on at least a portion of the activation assembly, wherein the load force is defined at least in part by a force generated as a result of the fall occurrence. In various embodiments, a relief apparatus may comprise an activation assembly that enables both an automated deployment and a manual deployment of a relief step device in a fall condition.

A relief apparatus and method of use for providing a flexible connection point between straps of a harness and mitigating suspension trauma for a user of the harness. In various embodiments, the relief apparatus comprises a base plate comprising one or more base strap slots and a central cavity defined by a cavity wall protruding out of a plane of the base plate, and an upper plate comprising one or more upper strap slots and an aperture configured to fit around the cavity wall of the base plate. The base plate and the upper plate are arrange concentrically along a central axis and may be configured to each rotate about the central axis. The relief apparatus further comprises a relief step comprised of a line and having a proximal end and a distal end, the distal end being secured to a deployment feature.

The present disclosure relates to a work safety management system using a safety belt unit for high-place work, and safety during working at a high place can be enhanced by determining whether a worker has fastened a seat belt to a safety structure, and the location of the worker, whether the seat belt is fastened and whether the work is on progress can be monitored in real time from a remote location to prevent safety accidents.

A fall-protection system including a harness and a fall-protection apparatus with a lifeline bearing a connector configured to be connected to the harness; and, a fall-protection monitoring system with a base unit and with at least one sensor module configured to sense a condition of the connector and to communicate a signal indicative of the condition of the connector to the base unit.

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.
