The D-ring 118 has a frame defining at least one opening through which a clip, such as a carabiner, a lanyard, or other rope or line, can be secured to connect the harness 100 to the line or the personal fall limiter device. The D-ring 118 may be integrated with the back plate 200.

[0064] With reference to FIG. 2, and with continued reference to FIGS. 1A-1B, a belt strap 300 configured for use with the harness 100 is shown. The belt strap 300 is connected to the first and second shoulder straps 110a, 110b in an adjustable manner that allows for movement of the belt strap 300 relative to the first and second shoulder straps 110a, 110b. In this manner, the position of the belt strap 300 relative to the first and second shoulder straps 110a, 110b may be adjusted based on the needs of each individual user. The belt strap 300 described herein may be formed from a substantially flat webbing material typically used in belt and harness construction, such as rayon, polyester, nylon or other materials known to those having skill in the art.

[0065] In some non-limiting embodiments or aspects, the belt strap 300 may be configured for movement between at least two positions relative to the straps of the harness 100. For example, the belt strap 300 may be configured for movement to a first position relative to the first and second shoulder straps 110a, 110b, wherein the belt strap 300 is configured for use as a tool belt, and a second position, wherein the belt strap 300 is configured for use during work positioning. When used as a tool belt, a desired position of the belt strap 300 is around the waist and lumbar area, so that a portion of the weight of the tools can be supported by the user's hips and waist, with the belt strap 300 providing back support. When used for work positioning, the desired position of the belt strap 300 is below the waist near the level of the hips, thereby creating a padded area for the user to lean and sit into. The belt strap 300 may be secured to the harness 100, such as the first and second shoulder straps 110a, 110b, via an adjustment mechanism 310 (shown in FIGS. 1A-1B) that maintains the belt strap 300 in a fixed position relative to the first and second shoulder straps 110a, 110b. When it is desired to move or adjust the position of the belt strap 300 relative to the first and second shoulder straps 110a, 110b, the adjustment mechanism 310 may permit movement of the belt strap 300 relative to the first and second shoulder straps 110a, 110b, as described herein.

[0066] In use, the belt strap 300 is configured for extending around at least a portion of a user's waist. The belt strap 300 has a first end 302 opposite a second end 304. In some embodiments or aspects, the first end 302 may be removably connectable to the second end 304, such as via a connector or a buckle. In embodiments or aspects where the first and second ends 302, 304 have buckles, a plurality of holes 305 (only two labeled for clarity) may be provided along the belt 300 to permit connection with the buckle. The first and second ends 302, 304 may also have a connector 306, shown as a D-ring, from which tools or other items may be suspended. In other embodiments or aspects, the first end 302 may be spaced apart from the second end 304 when the belt strap 300 is worn by the user.

[0067] With continued reference to FIGS. 1A-2, the belt strap 300 may have a belt pad 301 that provides padding to increase user comfort while using the belt strap 300. As shown in FIG. 2 As shown in FIG. 2, the belt pad 301 has a plurality of support straps 303 for securing the belt strap 300 against the belt pad 301. The space between the belt strap 300 and the belt pad 301 may receive parts of a harness 100, such as first and second shoulder straps 110a, 110b. With reference to FIGS. 3A-3B, the adjustment mechanism 310 may be configured for selectively raising or lowering a position of the belt strap 300 relative to other straps of the harness 100 and locking the belt strap 300 at a desired position between a lowered position and a raised position. Desirably, the belt strap 300 has a pair of adjustment mechanisms 310 proximate to the first and second ends 302, 304 of the belt strap 300. Each adjustment mechanism 310 may have an adjustment strap 312 having a first end 314 attached to at least one of the first and second shoulder straps 110a, 110b and a second, free end 316 that extends under the belt strap 300. The first end 314 of the adjustment strap 312 may be sewn, adhered to, or otherwise connected to at least one of the first and second shoulder straps 110a, 110b. By moving the second, free end 316 in a first direction, such as by pulling in an upward direction, the belt strap 300 may be raised relative to the first and second shoulder straps 110a, 110b. Conversely, by moving the second, free end 316 in a second direction opposite to the first direction, such as by pulling in a downward direction, the belt strap 300 may be lowered relative to the first and second shoulder straps 110a, 110b.

[0068] With continued reference to FIGS. 3A-3B, the second end 316 of the adjustment strap 312 may be routed under the belt strap 300 through an opening in an adjustment plate 321 that is connected to the belt strap 300. In this manner, the belt strap 300 is suspended from the harness 100 via the adjustment strap 316. In some non-limiting embodiments or aspects, the adjustment plate 321 may have a first slot 323 through which the webbing of the belt strap 300 is routed and a separate, second slot 322 through which the adjustment strap 312 is routed. In some non-limiting embodiments or aspects, the adjustment plate 321 may be a D-ring fixedly connected to the belt strap 300 with the adjustment strap 312 being routed through the opening of the D-ring.

[0069] In some non-limiting embodiments or aspects, such as shown in FIG. 5, the adjustment plate 321 can be replaced with a slotted grommet 320 extending through the belt strap 300. The slotted grommet 320 has a width and height that is larger than a width and thickness of the adjustment strap 312 such that the adjustment strap 312 can freely move through the slotted grommet 320. The free, second end 316 of the adjustment strap 316 is routed through the slotted grommet 320 such that the belt strap 300 is suspended from the harness 100 via the adjustment strap 316.

[0070] With reference to FIGS. 3A and 4, the adjustment mechanism 310 may include an adjustment buckle 318 that is connected to a front portion of one of the first or second shoulder straps 110a, 110b. The adjustment buckle 318 may be connected to one of the first or second shoulder straps 110a, 110b that is opposite to the other of the first or second shoulder straps 110a, 110b to which the first end 314 of the adjustment strap 312 is connected. In some non-limiting embodiments or aspects, the adjustment buckle 318 is directly connected to one of the first or second shoulder straps 110a, 110b. In some non-limiting embodiments or aspects, the adjustment buckle 318 is connected to one of the first or second shoulder straps 110a, 110b by way of a connecting strap 317. For example, the connecting strap 317 may be sewn, adhered to, or otherwise connected to one of the first or second shoulder straps 110a, 110b. As shown in FIG. 4, the connecting strap 317 may have a loop 319 configured to receive at least a portion of the adjustment buckle 318.

[0071] The adjustment buckle 318 is configured to receive the second end 316 of the adjustment strap 312 therethrough and permit selective movement of the adjustment strap 312, which in turn adjusts the position of the belt strap 300 relative to the harness 100. As shown in FIG. 4, the second end 316 of the adjustment strap 312 passes through the adjustment buckle 318 that is suspended from the connecting strap 317. The adjustment buckle 318 is operable between a locked state or configuration, in which the second end 316 of the adjustment strap 312 is fixed relative to the adjustment buckle 318, and an unlocked state or configuration, wherein the second end 316 of the adjustment strap 312 is movable relative to the adjustment buckle 318 to permit raising or lowering of the belt strap 300. The locking of the adjustment buckle 318 may be done by way of a strap clamp 325. The strap clamp 325 may be slidable on the adjustment buckle 318 between a first position and a second position. In the first position, the strap clamp 325 is retained tightly against the adjustment strap 312 so the second end 316 cannot move relative to the adjustment buckle 318. In the second position, the strap clamp 325 is moved away from the adjustment strap 312 so the second end 316 can move relative to the adjustment buckle 318. A strap hold 327 may be provided on one of the first or second shoulder straps 110a, 110b to prevent free movement of the second end 316 of the adjustment strap 312.

[0072] With reference to FIGS. 1B and 3B, the adjustment mechanism 310 may include a ladder latch 324 instead of the buckle 318. The ladder latch 324 a first end 326 and a second end 328 both attached to one of the first or second shoulder straps 110a, 110b. The first and second ends 326, 328 may be bolted, sewn, or tied to the first or second shoulder straps 110a, 110b. The first and second ends 326, 328 may be otherwise attached to the first or second shoulder straps 110a, 110b in another manner known to those having skill in the art. A plurality of teeth 330 (only one labeled for clarity) extend between the first and second ends 326, 328. A locking piece 332 is movable across the plurality of teeth 330, and lockable along any individual tooth 330. The locking piece 332 surrounds the ladder latch 324 and has a tiltable front portion 334 and a back portion (not shown). The front portion 334 may include one or more pawls that engage with one of the plurality of teeth 330 thereby locking the locking piece 332 at a desired location along the ladder latch 324. The tiltable front portion 334 is biased towards the plurality of teeth 330 so as to keep the pawls engaged with a tooth 330.

[0073] In order to adjust the position of the locking piece 332 along the plurality of teeth 330 of the ladder latch 324, a user may tilt the tiltable front portion 334 away from the plurality of teeth 330 thus disengaging the pawl from the tooth 330 to which it was engaged. While still tilting the front portion 334 away from the plurality of teeth 330, the user may slide the locking piece 332 upwards or downwards along length of the ladder latch 324. When the locking piece 332 is in a desired position, the user may release the tiltable front portion 334, so the pawls engage with a new tooth 330. This adjustment method can be used to move the locking piece 332 upwards or downwards along the length of the ladder latch 324.

[0074] After the second end 316 of the adjustment strap 312 is routed through the second slot 322 of the adjustment plate 321, the second end 316 is attached to the locking piece 332. The second end 316 may be attached to the back portion or a part of the tiltable front portion 334. It is contemplated that the second end 316 may be attached to the locking piece 332 in a manner known to those having skill in the art. In this configuration, as the locking piece 332 is moved along the length of the ladder latch 324, the adjustment strap 312 moves with the locking piece 332, raising and lowering the belt strap 300. In order to accommodate the ladder latch 324, the adjustment plate 321 may have a third slot 329 for receiving the ladder latch 324 and its respective components.

[0075] The adjustment mechanism 310 functions as a pulley, wherein the belt strap 300 can be raised or lowered by selectively moving the second end 316 of the adjustment strap 312 through the adjustment buckle 318 or the ladder latch 324 and locking the adjustment buckle 318 or locking piece 332 of the ladder latch 324 when the belt strap 300 is positioned at a desired orientation relative to the rest of the straps of the harness 100. In this configuration, the second slot 322 or the slotted grommet 320 acts as the pulley over which the adjustment strap 312 travels. When the adjustment strap 312 is pulled through the adjustment buckle 318 in a first direction or guided in a first direction by the locking piece 332 of the ladder latch 324, the belt strap 300 is raised relative to the harness 100 straps and the user. When the adjustment strap 312 is pulled through the adjustment buckle 318 in a second direction or guided in the second direction by the locking piece 332 of the ladder latch 324, the belt strap 300 is lowered relative to the harness 100 straps and the user.
