A connection arrangement for use with a wearable body harness includes a first connector having a first body component, a second body component, and an attachment element connected to each other by a rod having a longitudinal axis. The connection arrangement further includes a second connector removably connectable to the first connector. Each of the first body component, the second body component, and the attachment element are independently movable relative to each other about the longitudinal axis of the rod. The first connector and the second connector are removably connectable to each other via a locking and release mechanism between a first, locked configuration, where the first connector and the second connector are connected to each other, and a second, unlocked configuration, where the first connector and the second connector are disconnected from each other.

Systems, methods, and media for safety reinforcement for a personal protective equipment (PPE) device for a material handling vehicle are provided. The safety reinforcement system can include a control unit co-located with the material handling vehicle and configured to receive an identification from the PPE device, communicate the identification to a server, receive an operating routine for the identified PPE device from the server in response to the identification, receive a first operational data from the PPE device, and transmit a limiting instruction to a subsystem of the material handling vehicle according to the operating routine. The operating routine may comprise at least one of a translation routine and a governing rule. The limiting instruction may limit a function of the material handling vehicle.

Various embodiments illustrated herein disclose a full body harness that includes a connector. The connector includes a first plate and a second plate, where the first plate is identical to the second plate. The first plate and the second plate includes a plurality of slits to facilitate passage of a first harness and a second harness therethrough. The first plate is rotatably coupled to the second plate such that they are rotatable with respect to each other. Such a connector automatically enables easy adjustment of the harness based on an activity of a user who is wearing the harness.

A web harness system includes an upper webbing portion. A lower webbing portion is connected to the upper webbing portion. A sub-pelvic support portion is connected to the lower webbing portion. The sub-pelvic support portion is configured as a strap for placement under a user buttocks. A leg harness portion is connected to the sub-pelvic support portion. The leg harness portion includes: a first leg extension connected to a first portion of the sub-pelvic support portion and disposed at a position that aligns with a first side of a user hip; a second leg extension is connected to a second portion of the sub-pelvic support portion and disposed at a position that aligns with a second side of a user hip; a right leg adjustment belt is connected to the first leg extension; and a left leg adjustment belt is connected to the second leg extension.

A web harness system includes a sub-pelvic support portion. A leg harness portion is connected to the sub-pelvic support portion. The leg harness portion including: a first leg extension connected to a first portion of the sub-pelvic support portion; a second leg extension connected to a second portion of the sub-pelvic support portion; a right leg adjustment belt connected to the first leg extension; and a left leg adjustment belt connected to the second leg extension.

A convertible harness system which may be selectively transitioned between a utility belt, sit-harness, and full body harness, is herein disclosed. The convertible harness system may include a utility belt, a leg loop assembly, and a chest harness, wherein the leg loop assembly may be reversibly coupled to the utility belt by passing a primary attachment point of the leg loop assembly through an attachment slot/opening in the utility belt and securing the primary attachment point to the utility belt by girth-hitching the primary attachment point to the utility belt using a primary attachment loop coupled to the primary attachment point. The convertible harness system disclosed herein may enable a wearer rapidly and reversibly couple a leg loop assembly to a utility belt, without removing or unbuckling the utility belt, and without use of a carabiner or other conventional locking device.

A self-retracting lifeline system including a self-retracting lifeline including a retracting device and webbing extending from the retracting device, and a backpack energy absorber configured to attach to a harness at a back of a user wearing the harness, wherein the webbing includes a first end attached to the retracting device and a second end attached to the backpack energy absorber.

A strap adjuster including an adjustment knob and a biased pin, the adjustment knob having a first interior annular collar that is configured to accept the head of the biased pin thereinto, the first interior annular collar comprising a first circumferentially-oriented notch defined on one circumferential end by a circumferential wall and defined on a second, opposing circumferential end by a circumferential ramp.

An apparatus for reducing wearer fatigue for use in a wearable safety harness system includes a dorsal chassis capable of engagement with one or more shoulder safety straps and one or more lower torso webbing straps, an attachment subassembly comprising of a D-ring, a self-retracting lifeline attachment point, lower torso webbing strap attachment point, and a force-reduction mechanism. The attachment subassembly is attached to the dorsal chassis via the force-reduction mechanism such that force-reduction mechanism absorbs vertical forces produced by the weight of a self-retracting lifeline. The force-reduction mechanism absorbs vertical forces produced by the lower torso webbing strap resulting from the attachment of tools or equipment to the lower torso webbing strap. The arrangement of the apparatus also promotes increased flexibility between the shoulder safety straps and the lower torso webbing straps torso safety strap, thereby reducing wearer fatigue.

A safety monitoring harness system for the protection of a climber is disclosed. The safety monitoring harness system having a base, an alarm system, a strap length sensor assembly, a PCB, a first tether assembly, a second tether assembly and a power system. The first tether assembly and the second tether assembly each comprise a strap, a retraction assembly, and an anchoring hook. The safety monitoring harness system is configured to selectively attach to the climber by: securing a harness assembly to the climber, and securing the base to the harness assembly. A portion of the retraction assembly for each of the first tether assembly and the second tether assembly are enclosed within the base. The anchoring hook retract and extend between a plurality of lengths from the base.
