The present disclosure relates to a waist padding assembly comprising multiple portions made of various materials at various locations of the padding assembly to allow for improved force distribution, support, breathability, and ergonomics for an operator (also referred to as a “user”). Various components, materials, assemblies, devices, and methods are also provided. In some example embodiments, the waist padding assembly herein may be used to contact the back of a user at or proximate the user's waistline as part of a harness assembly. Various harnesses and padding arrangements for harnesses typically lack the ability to provide equal distribution of forces applied to the user's waist, lack breathability, provide poor ergonomic support (e.g., create pressure points), and/or are uncomfortable to wear. For example, the uneven distribution of force can cause discomfort to operators who may be required to wear the harness for extended periods of times while performing operations of daily work. Embodiments of the present disclosure solve one or more of the aforementioned problems.


In some embodiments, a waist padding assembly may be provided with a center portion and two side portions. The two side portions may be disposed on opposite sides of the center portion. While being worn, the center portion may be configured to substantially align with and at least partially contact the user's back and the two side portions may be configured to substantially align with and at least partially contact the user's respective left and right flanks (e.g., along the user's waistline). The center portion may be made of one or more materials, while the two side portions may include at least one different material. In some embodiments, the center portion may comprise a porous ethylene-vinyl acetate (EVA) material. The EVA material may be configured to be breathable while distributing forces along the user's back. For example, in some embodiments, the EVA material may be porous, including ventilation holes defined therein to allow cooling of the user's back. Each of the two side portions comprise a different material configured to provide lateral support to the operator. For example, the side portions may comprise a polyurethane (PU) foam. In some embodiments, the side portions may be sewn, adhered, and/or otherwise attached to the center portion.


In operation, during extended use, the center portion may experience constant or nearly constant pressure in the form of the operator's weight resting against the center portion. In such embodiments, the center portion may be made of a higher density and higher resilience material (e.g., EVA) than the side portions to offer strong support for the lumbar during use. In some embodiments, the two side portions may be configured to distribute weight and/or pressure from an operator when the operator applies additional pressure to the side portions during periodic movements (e.g., leaning, and/or the like). In some embodiments, the two side portions may comprise a PU foam, such as an integral skin foam (ISF). In some embodiments, ISF foam in the side portions may be configured to distribute pressure in the vertical direction. In various embodiments, example ISF side portions may be configured to recover to an initial state without plastic deformation (e.g., a compression set test result of 0 deformation after 24 hours compression). In some embodiments, the EVA material of the center portion may comprise a more rigid material than the ISF, wherein the EVA material of the center portion may be configured to provide more support to the lumbar of a user. In some embodiments, the EVA material of the center portion may be configured to distribute the pressure in a horizontal direction. In some embodiments, the EVA may be a high-density EVA (e.g., 65 kg/m3) with a higher hardness than the PU side portions (e.g., HC70).


In some embodiments, a back plate may provide further support to the center portion. The back plate may be made of, for example, thermoplastic polyurethane (TPU) (e.g., nylon) and may provide at least some additional rigidity to the EVA material. In some embodiments, the center portion may additionally include a 3D spacer fabric disposed along a first side of the center portion. The 3D spacer fabric may be configured to add breathability and comfort for the user. The first side of the center portion may be configured to contact the user's back. In some embodiments, the center portion may additionally include a warp mesh material disposed along a second side of the center portion, which may facilitate breathability while covering the EVA material. In some embodiments, the side portions may be attached directly to the EVA material.


In various embodiments, the waist padding assembly may include one or more retainers, which may define a passage to receive a belt configured to wrap around the user's waist, with the EVA material and PU material of the respective center and side portions being configured to be disposed between the user's waist and the belt. The belt may comprise one or more attachment rings configured to engage a rope, wire, clip, carabiner, pulley, or other retaining device through which at least some of the weight of the user is supported and force thereby applied to the user's waist while being cushioned and supported by the waist padding assembly.


As described herein, various embodiments of the present disclosure may include a waist padding assembly that utilizes a porous material and two side portions to provide an operator with improved force distribution, increased breathability, and increased ergonomics to ensure better wearability and long-term comfort.



FIGS. 1-11 depict exemplary views of an example waist padding assemblies and a harness assemblies and portions thereof in accordance with various embodiments of the present disclosure. FIGS. 1 and 5 depict a front view and a front perspective view of a waist padding assembly 100. The waist padding assembly 100 may comprise a center portion 110 and/or two side portions 112A, 112B (collectively “112”). In the depicted embodiment, the side portions 112A, 112B (e.g., a first side portion 112A and a second side portion 112B) are shown on opposite sides of the center portion 110. FIGS. 1-5 depict the center portion 110 and side portions 112A, 112B affixed as a single padding assembly, while FIG. 6 illustrates and exploded view prior to such assembly. Each of the side portions 112A, 112B may be secured to the center portion 110, for example, via affixation such as sewing, adhesive, and/or other means of attachment.


In various embodiments, two side portions 112 may comprise at least one different material than the center portion. In some embodiments, the side portion 112 may comprise a polyurethane (PU) foam material (e.g., HC28 hardness). The polyurethane material may be configured to help distribute peak pressure forces endured by an operator and to distribute the pressure across an area of the operator's flanks to reduce the maximum pressure on any one point or sub-area of the flanks. For example, in operation, the harness assembly (e.g., harness assembly 300 shown in FIGS. 10-11) may include a belt (e.g., belt 320B shown in FIGS. 10-11) that wraps around the user's back along or proximate the waistline. In some instances, the belt 320B may apply pressure to the operator's flanks due to the pinching action of the opposing sides of the belt coming together as the operator's body weight applies force to the belt. For example, as tension is applied to the illustrated O-rings 310B by the retainer device 330 illustrated in FIG. 11, the opposite sides of the belt may be urged towards each other, sandwiching the user therebetween. Thus, the cushioning ability and rigidity of the side portions may resist this force from the belt and distribute the force more evenly to reduce the peak pressure on the wearer and the peak force at any specific point relative to having a weaker (or no) side portion. In some embodiments, PU side portions 112 may provide improved performance under compression to consistently distribute the stress across the user's waistline. In various embodiments, the two side portions 112 may secure to the center portion 100 via any manner of attachment (e.g., sewing, adhesion, etc.). In some embodiments, the first side of the center portion 110 and/or the side portions 112 may be contoured, such as with the raised plateaus 114 illustrated in FIGS. 1-3, 5-7. In some embodiments, the EVA material may be contoured and/or a surface layer of 3D spacer fabric may be contoured.

In various embodiments, the backplate 200 may secure to the waist padding assembly 100 via any manner of attachment (e.g., sewing, adhesion, etc.). In various embodiments, the backplate 200 may secure to the waist padding assembly 100 at the center portion 110. For example, the back plate 200 may be the same shape or substantially the same shape as the center portion 110 and may be configured to align with the footprint of the center portion 110 to provide additional rigidity to the center portion. In other embodiments, the backplate 200 may secure to the waist padding assembly 100 proximate to the center portion 110. The backplate may for example, be made of a rigid material, such as thermoplastic polyurethane (TPU) and configured to limit or prevent flexion of the center portion caused by the belt (e.g., belt 320A shown in FIGS. 10-11) being pulled from either end.


With reference to FIG. 4, a rear perspective view of an example backplate 200 is depicted attached with a waist padding assembly 100 in accordance with various embodiments of the present disclosure.

The retainer(s) 214 and/or reflective section(s) 216 may be integrated into the assembly via any attachment (e.g., sewing, adhesion, etc.).


With reference to FIGS. 8-9, a cross-sectional view and exploded perspective view of the material of the center portion 110 are depicted in accordance with various embodiments of the present disclosure. In various embodiments, the center portion 110 may comprise two or more different materials. In some embodiments, at least one of the materials may be a porous ethylene-vinyl acetate (EVA) material with at least one layer at the front (e.g., first side, facing the user) and/or at the rear (e.g., the second side, facing away from the user towards the backplate). In the embodiment depicted in FIGS. 8-9, the center portion 110 comprises at least three layers (e.g., front layer 110A, middle layer 110B, and rear layer 110C). In various embodiments, the front layer 110A may comprise a 3D spacer fabric material, the middle layer 110B may comprise the porous EVA material, and/or the rear layer 110C may comprise the warp mesh material. The 3D spacer fabric may be disposed along the first side of the center portion 110 and configured to engage with a first side of the middle layer 110B of the center portion 110 (e.g., the porous EVA material). The warp mesh material may be disposed along the second side of the center portion 110 may configured to engage with a second side of the middle layer 110B of the center portion 110 (e.g., the porous EVA material). In various embodiments, the front layer 110A (e.g., the 3D spacer fabric) and the rear layer 110C (e.g., the warp mesh material) may be disposed linearly opposite of each other on opposing sides of the middle layer 110B. The warp mesh material layer 110C and the 3D spacer fabric layer 110A may be at least in parallel to each other relative to a length of the waist padding assembly 100. In some embodiments, the side portions 112 may comprise only PU foam.


With further reference to FIG. 8, in various embodiments, a first side of the center portion (e.g., first layer 110A) may be configured to contact the back of the harness operator. The first layer 110A of the center portion 100 may provide at least some cushion and breathability upstream of the middle layer 110B. The 3D spacer fabric material may be configured to absorb moisture created from the contact between the center portion and the back of the operator while creating voids (e.g., via the 3D shape of the fabric and/or the pores in the fabric) for ventilation and evaporation of the moisture. The 3D spacer fabric material may further allow for increase air flow to and through the middle layer 110B.


3D spacer fabric may comprise multiple layers itself. The 3D spacer fabric may include two surface layers on opposing sides with a “spacer” layer between the two surface layers. In some embodiments, the surface layers may be a mesh construction to allow airflow therethrough. The spacer layer may comprise vertical filler strands that define a thickness (e.g., variable or constant thickness along the fabric) of the 3D spacer fabric. In some embodiments, the 3D spacer fabric thickness may be adjusted to define a pattern, such as the waffle pattern of the front layer shown in FIG. 8 or the linear pattern shown in FIG. 9. The 3D spacer layer may allow ventilation with its porous design and/or with its patterned surface thickness to facilitate airflow between the surface layers and parallel to the surface layers. The warp mesh fabric may be warp knit into a mesh to provide strength and breathability.


With further reference to FIG. 9, in various embodiments, the porous EVA material may comprise a plurality of holes 111. In some embodiments, the plurality of holes 111 may be arranged in a pattern throughout the EVA material to control the porosity of and thus the airflow through the depicted middle layer 110B. The plurality of holes may be aligned with each other (e.g., aligned along a same or substantially the same direction relative to a flat configuration of the EVA material) and configured to be oriented towards a back of a user (e.g., from front-to-rear in the depicted orientation), such that the plurality of holes are configured to assist in the breathability of the center portion 110. In the depicted embodiments, the plurality of holes 111 are oriented perpendicular to a length of the waist padding assembly 100.

With reference to FIGS. 10-11, in various embodiments the waist padding assembly may be configured to be a portion of a harness assembly in accordance with various embodiments of the present disclosure. In one or more embodiments, the waist padding assembly 100 may be configured to be a portion of a harness assembly 300. The harness assembly 300 may be worn by an operator, for example, to protect the operator from falls (e.g., in a utility, industrial, recreational, or other elevated operating situation). The harness assembly 300 may include a plurality of straps 320A, 320B for engaging and/or supporting the operator, in accordance with known harness configurations but for the presently improved assemblies.


The plurality of straps may include a belt 320A configured to support at least a portion of the operator's weight as part of the harness assembly. In the embodiment depicted in FIGS. 10-11, the belt 320A is connected to an attachment ring 310B at each respective end. The attachment rings 310B may be configured to engage a retainer device 330 (e.g., a rope, wire, clip, carabiner, pulley, fall prevention device, or other retaining device) to apply a force to the belt via the attachment rings. The force applied to the belt thereby applies pressure to the user via the belt acting on the waist padding assembly 100 and backplate 200 as described herein. The belt 320 pass through one or more retainers (e.g., retainers 218 on the backplate shell 210 and/or separate retainers 214) to locate the belt against the waist padding assembly 100 and/or backplate 200 and direct the force of the belt therethrough to the user's waistline. The materials and structure of the waist padding assembly 100 and/or backplate 200 described herein may thereby improve force distribution, support, breathability, and ergonomics for the user to allow the user to comfortably work for extended periods. In some embodiments, the overall size (e.g., height and/or length) of the waist padding assembly may be adjusted to suit the size of the harness and/or operator.
