Description

BACKGROUND

Technical Field

The present disclosure relates generally to wearable body harnesses and, in particular, to a harness back plate and strap arrangement of a wearable body harness.

Technical Description

As is known in the art, there exist various safety devices and arrangements that can be worn by or attached to a user to ensure the wearer's safety in certain situations. Such mechanisms come in many forms, including, but not limited to, harnesses and safety belts. Full body harnesses are widely used for lifting and lowering individuals in dangerous situations and as a primary component in a personal fall arrest system. These harnesses can also be used for work positioning, travel restriction, ladder climbing, rescue retrieval, and evacuation. While these harnesses are used mainly in an industrial setting, and particularly the construction industry where the likelihood and danger of falls from heights is both numerous and significant, a full body harness can be used in various other applications in which total suspension and support of the body must be ensured, either expectedly or unexpectedly.

While there are many variations in full body harness construction, all typically include a plurality of elongate straps that are combined to fit around a user's body. In some embodiments or aspects, a full body harness may have an attachment point (D-ring) typically positioned in a central portion of the user's back or chest, and a plurality of straps routed around predetermined portions of the user's body in such a manner as to hold or suspend the user in the event of a fall.

While a variety of full body harnesses exist in the art, there is a continued need in the art for improved harnesses. Elongated straps naturally curl at angles which frequently cause discomfort to the user and create difficulty in adjusting the straps. There is also continued need in the art for improving the management of elongated straps to prevent curling.

In some non-limiting embodiments or aspects, and with reference to FIG. 1, the present disclosure is directed to a safety harness 100 (hereinafter referred to as “harness 100”) used in a fall protection system. The harness 100 has a plurality of straps that are arranged to support the user's body in an event of a fall. The harness 100 has a harness connection arrangement configured for releasably coupling at least a pair of straps of the harness 100.

With continued reference to FIG. 1, the harness 100 has at least two leg straps 102 configured to attach around a user's legs below a user's groin area. When attached, the leg straps 102 loop around or encircle each of the user's legs. Each leg strap 102 has a first end 102a that is removably attachable to a second end 102b via a connector 104 that permits removable attachment of the first end 102a to the second end 102b of each leg strap 102. In some non-limiting embodiments or aspects, the at least one connector 104 and/or the leg strap 102 may have at least one adjustment mechanism 106 configured for adjusting the length of each leg strap 102. As shown in FIG. 1, the adjustment mechanism 106 is connected to the second end 102b, but the adjustment mechanism 106 may instead be connected to the first end 102a. Each leg strap 102 is connected to a seat strap 108 at an intermediate portion 102c of the leg strap 102 between the first end 102a and the second end 102b. The seat strap 108 may extend across a user's lower back, buttocks, or an upper portion of the leg when the harness 100 is in use, depending on the user's size. Each leg strap 102 may be formed from a substantially flat webbing material typically used in harness construction, such as rayon, polyester, nylon or other materials known to those having skill in the art.

When applying a leg strap 102 to a leg of a user, the intermediate portion 102c may wrap around the back of a user's leg at or below the buttocks. The first end 102a and the second end 102b may wrap around the front of a user's leg and connect at a point on the user's thigh by way of the connector 104. The adjustment mechanism 106 can then be used to adjust the length of the leg strap 102 and increase or decrease the tightness of the leg strap 102 around the user's leg. It is contemplated that the connector 104 may be any suitable connector known to those having skill in the art. For example, the connector 104 may be a buckle-type or a belt-type connector. It is further contemplated that the adjustment mechanism 106 may be any suitable adjustment mechanism known to those having skill in the art. For example, the adjustment mechanism 106 may be a sliding adjustment buckle.

With continued reference to FIG. 1, the harness 100 further has a pair of shoulder straps 110 configured to extend over at least a portion of the user's shoulders. The shoulder straps 110 may have a first shoulder strap 110a and a second shoulder strap 110b arranged to overlap one another in an X-shaped configuration, with the shoulder straps 110a, 110b configured to be connected at the user's chest area via a chest connector 120. Like the connector 104, the chest connector 120 may be any suitable connector, such as a buckle, known to those having skill in the art.

In this manner, the shoulder straps 110a, 110b are configured to cross over each other at a rear portion of the harness 100 worn on the user's back. As described herein, the harness 100 may have a back plate 200 through which the first shoulder strap 110a and the second shoulder strap 110b can be routed to maintain the first shoulder strap 110a and the second shoulder strap 110b in the X-shaped configuration. The first shoulder strap 110a may cross a longitudinal axis of the back plate 200 and the second shoulder strap 110b when forming an X-shaped configuration. The second shoulder strap 110b may also cross the longitudinal axis of the back plate 200 as well as the first shoulder strap 110a. In some embodiments or aspects, neither the first shoulder strap 110a nor the second shoulder strap 110b may cross the longitudinal axis of the back plate 200 or the other shoulder strap. In other embodiments or aspects, the second shoulder strap 110b may not cross the longitudinal axis of the back plate 200 or the first shoulder strap 110a. In these embodiments, the first and second shoulder straps 110a, 110b may stay on one half of a user's body.

After the routing through the back plate 200, the shoulder straps 110a, 110b may extend downward and beyond the back plate 200 in generally opposite directions, maintaining the X-shaped configuration, until the first shoulder strap 110a and the second shoulder strap 110b reach the first ends 102a of the leg straps 102. The first and second shoulder straps 110a, 110b may either connect to the first ends 102a of the leg straps, or the first ends 102a of the leg straps may be a distal end of the first and second shoulder straps 110a, 110b. Like the leg straps 102, the shoulder straps 110a, 110b may be formed from a substantially flat webbing material typically used in harness construction, such as rayon, polyester, nylon or other materials known to those having skill in the art.

As further shown in FIG. 1, the harness 100 may have a back strap 116 connecting a substantially intermediate portion of the first shoulder strap 110a with a substantially intermediate portion of the second shoulder strap 110b. The back strap 116 may extend across a user's back to provide support and to maintain a set distance between the first shoulder strap 110a and the second shoulder strap 110b as they extend beyond the back plate 200 and down and along a user's back. The first and second shoulder straps 110a, 110b may be connectable together at a front portion of the harness 100 in an area of the user's chest. In some non-limiting embodiments or aspects, the first and second shoulder straps 110a, 110b may have at least one connection arrangement 120 or chest connector, such as a buckle, configured to releasably connect the first and second shoulder straps 110a, 110b to each other.

As further shown in FIG. 1, the harness 100 has an anchor element, such as a D-ring 118, for connecting at least a portion of the shoulder straps 110a, 110b to a line fixed to an attachment, anchor point, or to a personal fall limiter device. 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.

With reference to FIG. 2, a detailed rear view of a portion of the harness 100 shows the back plate 200 in accordance with some non-limiting embodiments or aspects of the present disclosure. The back plate 200 is configured to route the first and second shoulder straps 110a, 110b across one another such that the first and second shoulder straps 110a, 110b have an X-shaped configuration. The back plate 200 has a body 202 having a plurality of openings 204 configured for routing at least a portion of the first and second shoulder straps 110a, 110b through the back plate 200. The back plate 200 has the D-ring 118 connected thereto in a manner such that the first and second shoulder straps 110a, 110b are routed to prevent removal of the D-ring 118 from the back plate 200. The D-ring 118 may be connected to a personal fall limiter (PFL) 124 or a lanyard to allow the back plate 200 and harness 100 to be connected to a fixed anchor point.

As shown in FIG. 2, the shoulder straps 110a, 110b are routed through similar pathways through the openings 204 of the back plate 200. The first and second shoulder straps 110a, 110b are routed through the back plate 200 by weaving through a plurality of pathways defined by the openings 204. These pathways keep the shoulder straps 110a, 110b neatly organized across the back plate 200 and prevent undesirable tangling or bunching of the shoulder straps 110a, 110b across a user's back.

With reference to FIGS. 3-4B, the body 202 of the back plate 200 has a recess 206. The recess 206 may be defined between a pair of tabs 208a, 208b protruding from the body 202 and may be used for receiving at least a portion of the D-ring 118 or other attachment. The recess 206 is positioned between the lower guide slots 224a, 224b and the upper guide slots 226a, 226b (shown in FIG. 6A). As shown in FIG. 4B, each of the tabs 208a, 208b has a first end 238a, 238b connected to the body 202 of the back plate 200 and a second, free end 240a, 240b opposite the first end. The second ends 240a, 240b of the tabs 208a, 208b are arranged opposite one another with the space 210 defined therebetween. In some embodiments or aspects, the tabs 208a, 208b may be non-removably connected to the body 202 of the back plate 200. For example, the tabs 208a, 208b may be monolithically formed with the body 202, such as by being molded with the body 202 as a single piece so that first ends 238a, 238b are integral with the body 202. In other embodiments or aspects, the tabs 208a, 208b are formed as a separate component from the body 202 and are removably or non-removably connected to the body 202.

The tabs 208a, 208b may be deflectable to widen the space 210 and allow insertion of the D-ring 118 into the recess 206. As shown in FIG. 3, the first and second shoulder straps 110a, 110b are routed over the tabs 208a, 208b to prevent removal of the D-ring 118 from the recess 206 through the space 210.

At least one of the tabs 208a, 208b, such as the first tab 208a, has a projection 212 that is spaced apart from the body 202 of the back plate 200 by a distance D. Distance D is configured to be larger than a width of a connector 216 (shown in FIG. 5B) used for connecting the PFL 124 to the harness 100. As discussed herein, the projection 212 may be arranged substantially parallel with the body 202. In other embodiments or aspects, the projection 212 is arranged at an obtuse or an acute angle relative to the body 202.

As shown in FIG. 3, the projection 212 spaces the first and second shoulder straps 110a, 110b from the first tab 208a such that a clearance space 214 is formed between the first and second shoulder straps 110a, 110b and the first tab 208a. The clearance space 214 is configured to receive the connector 216, which is shown as a carabiner in FIG. 4B.

With reference to FIGS. 6A-6C, the back plate 200 is shown without the first and second shoulder straps 110a, 110b. The back plate 200 has a generally Y-shaped configuration with a core 218 and a pair of branches 220a, 220b branching away from the core 218. In use, the back plate 200 is arranged such that the branches 220a, 220b are pointed in an upward direction when worn by the user. In some embodiments or aspects, the branches 220a, 220b are arranged at an angle α relative to a central longitudinal axis 222 of the back plate 200. Angle α may be between 40° and 65°. It is contemplated that angle α may be outside of the 40-65° range so long as the first and second shoulder straps 110a, 110b remain aligned over a user's shoulders during use.

Each of the branches 220a, 220b has the plurality of upper openings 204 formed as elongated slots extending through the body 202 of the back plate 200. Similarly, the core 218 has a pair of lower openings 205 at its lower end for receiving the first and second shoulder straps 110a, 110b. The lower openings 205 are configured for routing at least a portion of the first and second shoulder straps 110a, 110b through the back plate 200 such that the first and second shoulder straps 110a, 110b are arranged in a direction extending from the central longitudinal axis 222 to an angle similar to angle α. In other words, the first and second shoulder straps 110a, 110b are arranged from the branches 220a, 220b in a direction generally extending along the user's spine and then toward the user's waist in a direction as dictated by the lower openings 205.

Due to the angle of the branches 220a, 220b relative to the longitudinal axis 222 and the core 218, the first and second shoulder straps 110a, 110b are bent in directions that may cause the webbing of the straps to curl, bunch up, or pucker. In order to eliminate such curling, bunching, or puckering of the webbing of the first and second shoulder straps 110a, 110b, the back plate 200 has a pair of lower guide slots 224a, 224b extending through the core 218 and a pair of upper guide slots 226a, 226b extending through the branches 220a, 220b. The lower and upper guide slots 224a, 224b, 226a, 226b are configured to receive first and second shoulder straps 110a, 110b and to facilitate bending of the webbing of the first and second shoulder straps 110a, 110b in a manner to prevent the bunching or puckering of the webbing material. This arrangement of guide slots 224a, 224b, 226a, 226b manages to keep the first and second shoulder straps 110a, 110b smooth when traversing along the back plate 200 and along a user's body.

With continued reference to FIGS. 6A-6C, the lower guide slots 224a, 224b are positioned below the tabs 208a, 208b defining the recess 206. A first lower guide slot 224a is configured to receive the first shoulder strap 110a, while the second lower guide slot 224b is configured to receive the second shoulder strap 110b. Each of the lower guide slots 224a, 224b has a first side 228 having a first length L₁ and a second side 230 having a second length L₂. The first and second sides 228, 230 are connected to each other and arranged to form a substantially L-shaped arrangement. In some embodiments or aspects, the first length L₁ may be longer than the second length L₂. In other embodiments or aspects, the first length L₁ may be equal to or shorter than the second length L₂. The first side 228 and the second side 230 define an angle β₁ therebetween. In some embodiments or aspects, the angle β₁ may be between 80° and 120°. It is contemplated that the angle β₁ may be outside of the 80-120° range so long as the first and second shoulder straps 110a, 110b can be routed through the back plate 200 without puckering of the webbing material. The first sides 228 of the first and second lower guide slots 224a, 224b may be arranged at an angle γ1 relative to the longitudinal axis 222. In some embodiments or aspects, the angle γ1 may be between 0° and 30°. In some embodiments or aspects, the second side 230 may define an angle of 0° to 25° relative to a line that is perpendicular to the longitudinal axis 222. Each of the first and second sides 228, 230 has a width that is wider than a thickness of the webbing of the first and second shoulder straps 110a, 110b.

The upper guide slots 226a, 226b are positioned above the tabs 208a, 208b defining the recess 206. A first upper guide slot 226a is configured to receive the second shoulder strap 110b, while the second upper guide slot 226b is configured to receive the first shoulder strap 110a, with the first and second shoulder straps 110a, 110b overlapping and crossing over each other and between the lower guide slots 224a, 224b and the upper guide slots 226a, 226b. Each of the upper guide slots 226a, 226b has a first side 232 having a first length L₃ and a second side 234 having a second length L₄. The first and second sides 232, 234 are connected to each other and arranged to form a substantially L-shaped arrangement. In some embodiments or aspects, the first length L₃ may be longer than the second length L₄. In other embodiments or aspects, the first length L₃ may be equal to or shorter than the second length L₄. The first side 232 and the second side 234 define an angle β₂ therebetween. In some embodiments or aspects, the angle β₂ may be between 80° and 120°. The first sides 232 of the first and second upper guide slots 226a, 226b may be arranged at an angle γ2 relative to the longitudinal axis 222. In some embodiments or aspects, the angle γ2 may be between 0° and 30°. Each of the first and second sides 232, 234 has a width that is wider than a thickness of the webbing of the first and second shoulder straps 110a, 110b. The upper guide slots 226a, 226b may be arranged such that the second side 234 of each slot is positioned opposite the second side 230 of the lower guide slots 224a, 224b. In some embodiments, the back plate 200 may also have slots 235 for receiving other attachments therethrough.

As shown in FIG. 7, at least a portion of the back plate 200, such as the tabs 208a, 208b, may have a locking slot 242 for receiving a clip 244. The clip 244 is configured to extend over the space 210, thereby preventing removal of the D-ring 118 or similar attachment. The clip 244 has hooks 245a, 245b configured to engage with the locking slot 242, thus permitting the clip 244 to be removably connected to the locking slot 242 to permit removal of the D-ring 118 when the clip 244 is removed. The clip 244 may have hooks 245a, 245b configured to engage at least a portion of the locking slot 242 in order to remain in place over the space 210. The hooks may engage and disengage the locking slot 242 by squeezing the clip 244. This permits the clip 244 to slide into and out of the locking slot 242. When the locking clip 244 is inside the slot, the squeezing may cease allowing the hooks 245a, 245b to press against the locking slot 242 in a frictional fit. The hooks 245a, 245b may also hook around a locking peg (not shown) within the slot 242 permitting the clip 244 to be locked in place within the locking slot 242. The locking clip 244 may then be squeezed and removed in a manner opposite of its insertion in order to no longer obstruct the space 210.

In some non-limiting embodiments or aspects, such as shown in FIG. 8, the back plate 200 may have a back pad 246. The back pad 246 may be made from a soft material, such as padding or foam, to cushion the user's back from the back plate 200 and the first and second shoulder straps 110a, 110b. The back pad 246 is positioned between the back plate 200 and the user so as to prevent direct contact between the back plate 200 and the user. The back pad 246 may take the same generally Y-shaped configuration as the core 218 of the back plate 200. However, the back pad 246 is larger than the back plate 200 so as to prevent contact between the back plate 200 and the user if the back plate 200 shifts during use. A back pad 246 larger than the back plate 200 may also prevent part of the user's shoulders from contacting portions of the first and second shoulder straps 110a, 110b. For example, the back pad 246 may be positioned between the user's back and the first and second shoulder straps 110a, 110b.

With reference to FIGS. 9A and 9B, the shoulder straps 110, such as the first and second shoulder straps 110a, 110b, have a pre-formed fold 400 configured to position the first and second shoulder straps 110a, 110b away from the user's neck. Due to the flexible nature of the webbing of the first and second shoulder straps 110a, 110b, the straps 110a, 110b have a natural tendency to take a most direct path between the rear portion of the harness 100 at the back plate 200 and a front portion of the harness 100 at the connector 106, thereby interfering with the user's neck (see FIG. 10B). The pre-formed fold 400 positions the first and second shoulder straps 110a, 110b away from the user's neck (see FIG. 10A), thereby increasing the user's comfort while wearing the harness 100.

With continued reference to FIGS. 9A and 9B, wherein only the first shoulder strap 110a is shown for clarity of illustration, the fold 400 is formed by folding the first shoulder strap 110a over itself between a first end 402 and a second end 404. The first shoulder strap 110a has a first section 408 and a second section 412 extending in opposite directions from the fold 400 as the first shoulder strap 110a sits atop a user's shoulder. The fold 400 may be formed by folding the first shoulder strap 110a such that a top surface 406 of a first section 408 abuts a top surface 410 of a second section 412 of the first shoulder strap 110a. The folded sections may be stitched together by stitching 414. The stitching 414 may extend across the first shoulder strap 110a in the direction of the user's neck, along the first shoulder strap 110a in the direction of the front side and backside of the user, or, as shown in FIG. 9B, in both directions. The first section 408 and the second section 412 define an angle σ therebetween. In some embodiments or aspects, the angle σ may be between 110° and 155°, such as 140°. The first section 408 may have the same or different length than the second section 412. With reference to FIG. 10A, the shoulder straps 110, such as the first and second shoulder straps 110a, 110b with the pre-formed fold 400, are configured to be positioned on the user's shoulders such that pre-formed fold 400 is positioned away from the user's neck.
