Abstract

Apparatus and associated methods relate to a fall-protection safety harness having padding structures located at harness pressure points, including dorsal and shoulder regions, the lumbar region, and leg regions. The padding structures may be constructed to provide air-flow parallel to a wearer's skin. Air may flow through wearer-webbing channels created by displacing a webbing via comfort pads. For example, the padding structures may be made by sandwiching foam pads between mesh fabric materials. The foam pads may be captured by the two mesh fabrics using circumferential stitching, for example. Circumferential stitching may permit the foam to retain its uncompressed form which may facilitate webbing displacement. Separate and symmetric pads may be located on both sides of a wearer's spine, both at the lumbar region and at the dorsal region of the back, permitting airflow between pads and along the wearer's spine.

First claim

What is claimed is:

1. A fall-protection safety harness comprising:
a webbing configured to be worn by a wearer, the webbing comprising a suspender section, a right leg-loop strap attached to a right side of the suspender section and a left leg-loop strap attached to a left side of the suspender section, the suspender section having two suspender straps;
a waist strap coupled to the webbing, wherein the suspender section attaches to both the right and the left leg-loop straps at approximately waist strap connection locations;
a Y-shaped back-pad assembly sewn to the webbing and disposed between the suspender section and a wearer's dorsal region and a wearer's shoulders when worn, the Y-shaped back-pad assembly comprising a wearer-contacting layer of mesh material, a plurality of foam pads, and a webbing-contacting layer of mesh material, each one of the plurality of foam pads being captured by the wearer-contacting layer and the webbing-contacting layer circumscribing the pad, wherein an air channel providing airflow substantially parallel to a wearer's skin is formed between each pair of adjacent foam pads of the Y-shaped back-pad assembly; and,
a lumbar-pad assembly sewn to the waist strap and disposed between the waist strap and a wearer's lumbar region when worn, the lumbar-pad assembly comprising a perforated flexible support structure sandwiched between a wearer-contacting layer of mesh material and a waist-strap contacting mesh material, the lumbar-pad assembly further comprising a plurality of pairs of adjacent foam pads positioned between the wearer-contacting layer and the perforated flexible support structure, each one of the foam pads of the plurality of pairs of foam pads being captured by the wearer-contacting layer and the perforated flexible support structure circumscribing the pad, wherein, when the lumbar pad assembly is worn by the wearer, a plurality of air channels providing airflow directly adjacent and substantially parallel to the wearer's skin are formed between adjacent foam pads in each pair of the plurality of pairs of adjacent foam pads of the lumbar-pad assembly.

2. The fall-protection safety harness of claim 1 , further comprising a horizontal back strap connector attached to the two suspender straps at a wearer's back when worn.

3. The fall-protection safety harness of claim 1 , further comprising a D-ring coupled to the suspender section, wherein the two suspender straps thread through a webbing aperture of the D-ring.

4. The fall-protection safety harness of claim 1 , further comprising two side D-rings, a right side D-ring attached to the waist strap near a wearer's right hip region when worn and a left side D-ring attached to the waist strap near a wearer's left hip region when worn.

5. The fall-protection safety harness of claim 4 , further comprising a belt coupled to the two side D-rings.

6. A fall-protection safety harness comprising:
a webbing configured to be worn by a wearer, the webbing comprising a suspender section, a right leg-loop strap attached to a right side of the suspender section and a left leg-loop strap attached to a left side of the suspender section, the suspender section having two suspender straps coupled to each other at a crisscross point proximate a dorsal region of a wearer's back when worn;
a waist strap coupled to the webbing, wherein the suspender section attaches to both the right and the left leg-loop straps at approximately waist strap connection locations;
a plurality of suspender comfort pads sewn to the webbing and disposed between the suspender section of the webbing and a wearer's dorsal region and shoulders when worn, each one of the plurality of suspender comfort pads comprising mesh fabric and foam, wherein an air channel providing airflow substantially parallel to a wearer's skin is formed between each adjacent pair of suspender comfort pads;
a right-leg comfort pad coupled the right leg-loop strap and disposed between the right leg-loop strap and a wearer's right upper leg when worn, the right-leg comfort pad comprising mesh fabric and foam;
a left-leg comfort pad coupled the left leg-loop strap and disposed between the left leg-loop strap and a wearer's left upper leg when worn, the left-leg comfort pad comprising mesh fabric and foam; and,
a lumbar-pad assembly sewn to the waist strap and disposed between the waist strap and a wearer's lumbar region when worn, the lumbar-pad assembly comprising a perforated flexible support structure sandwiched between a wearer-contacting layer of mesh material and a waist-strap contacting mesh material, the lumbar-pad assembly further comprising a plurality of pairs of adjacent foam pads positioned between the wearer-contacting layer and the perforated flexible support structure, each one of the foam pads of the plurality of pairs of foam pads being captured by the wearer-contacting layer and the perforated flexible support structure circumscribing the pad, wherein, when the lumbar pad assembly is worn by the wearer, a plurality of air channels providing airflow directly adjacent and substantially parallel to the wearer's skin are formed between the adjacent foam pads in each pair of the plurality of pairs of adjacent foam pads of the lumbar-pad assembly.

7. The fall-protection safety harness of claim 6 , further comprising a horizontal back strap connector attached to the two suspender straps at the wearer's back when worn.

8. The fall-protection safety harness of claim 6 , further comprising a D-ring coupled to the suspender section, wherein the two suspender straps thread through a webbing aperture of the D-ring at approximately the crisscross point.

9. The fall-protection safety harness of claim 6 , further comprising two side D-rings, a right side D-ring attached to the waist strap near a wearer's right hip region when worn and a left side D-ring attached to the waist strap near a wearer's left hip region when worn.

10. The fall-protection safety harness of claim 9 , further comprising a belt coupled to the two side D-rings.

11. The fall-protection safety harness of claim 6 , wherein each of the plurality of suspender comfort pads are encapsulated by circumferential stitching.

12. The fall-protection safety harness of claim 6 , wherein the mesh fabric comprises spacer mesh material.

13. The fall-protection safety harness of claim 6 , wherein each of the plurality of lumbar comfort pads are encapsulated by circumferential stitching.

14. The fall-protection safety harness of claim 13 , further comprising a perforated flexible support structure having a perforation pattern of holes in a honeycomb arrangement, the perforated flexible support structure disposed between the waist strap and the wearer's lumbar region, when worn.

15. The fall-protection safety harness of claim 6 , wherein the each one of right-leg and left-leg two comfort leg-pads is attached to the webbing with sew patterns that are transverse to a direction of the webbing to permit air to flow between the webbing and the leg-pads.
