Abstract

Apparatus and associated methods may relate to a Self-Retracting Lifeline Connecting System (SRLCS) that securely attaches to a fall-protection safety harness, and further provides connections to a plurality of safety devices. In an illustrative example, the SRLCS may include a D-pad adapted for rear attachment to a back-pad of a safety harness. In some examples the D-pad may have webbing apertures through which two sections of webbing may be threaded in a criss-crossed manner. In some embodiments, the D-pad may provide an attachment for a first harness ring. In some exemplary embodiments, the D-pad may also provide a tunnel structure for routing a second harness ring therethrough. In an illustrative example, the tunnel may be located immediately adjacent the criss-cross location of the two sections of webbing, thereby permitting a carabiner to make use of the tunnel to capture the two sections of webbing.

First claim

What is claimed is:

1. A fall-protection safety apparatus for connecting a webbed safety harness to Self-Retracting Lifelines (SRLs), the apparatus comprising:
a first unitary body with a top surface and a bottom surface, the body comprising:
a first pair of webbing apertures, each aperture of the first pair extending through the body between the top surface and the bottom surface, and each aperture of the first pair having a first major dimension sized to receive a webbing having up to a predetermined width and having a first minor dimension sized to receive a thickness of the webbing, and the two apertures of the first pair aligned to each other such that the first major dimensions of both apertures of the first pair are substantially parallel to each other, the apertures of the first pair arranged such that a first intersecting line intersects both apertures of the first pair permitting a first linear portion of the webbing to be threaded sequentially through both apertures of the first pair; and
a second pair of webbing apertures, each aperture of the second pair extending through the body between the top surface and the bottom surface, and each aperture of the second pair having a second major dimension sized to receive the predetermined width of the webbing and having a second minor dimension sized to receive the webbing's thickness, and the two apertures of the second pair aligned to each other such that the second major dimensions of both apertures of the second pair are substantially parallel to each other and such that a second intersecting line intersects both apertures of the second pair permitting a second linear portion of the webbing to be threaded sequentially through both apertures of the second pair, and the second pair of apertures further aligned such that the first linear portion of webbing and the second linear portion of webbing form a criss-crossing pattern at or near a point of coincidence that corresponds to a point at which the first intersecting line crosses the second intersecting line;

a second unitary body connecting to the first unitary body, the second unitary body providing a tunnel sized to accommodate a carabiner, the tunnel oriented approximately parallel to the top surface of the first unitary body, and the tunnel located at or near the point of coincidence permitting the carabiner to capture both of said portions of webbing simultaneously at or near a location of the criss-crossing pattern;
the apparatus further comprising said webbing connected to the first unitary body by passing through the webbing apertures such that the two portions of webbing provide the criss-crossing pattern at or near the point of coincidence, the webbing capable of being secured to another object;
the apparatus further comprising the carabiner inserted through the tunnel of the second unitary body and capturing the criss-crossing pattern;
the apparatus further comprising two SRLs attached to the carabiner; and,
the apparatus further comprising a pivotable webbing retainer clip having an opening through which the criss-crossing pattern of webbing portions is threaded to retain the criss-crossing pattern between the webbing retainer clip and a first portion of the carabiner, the retainer clip configured to snap onto the carabiner.

2. The fall-protection safety apparatus of claim 1 , wherein the first unitary body is curved to form to a portion of a human body.

3. The fall-protection safety apparatus of claim 1 , wherein the webbing retainer is configured to snap onto a second portion of the carabiner opposite the first portion of the carabiner, thereby dividing the carabiner laterally into a first section and a second section wherein a first of the two SRLs is attached to the carabiner within the first section and a second of the two SRLs is attached to the carabiner within the second section.

4. A fall-protection safety apparatus for connecting a webbed safety harness to Self-retracting Lifelines (SRLs), the apparatus comprising:
a D-pad having a top surface and a bottom surface, the D-pad comprising:
a first slotted aperture extending through the D-pad between the top surface and the bottom surface, the first slotted aperture having a first long dimension and a first short dimension;
a second slotted aperture extending through the D-pad between the top surface and the bottom surface, the second slotted aperture having a second long dimension and a second short dimension, the second slotted aperture located such that the second long dimension is substantially parallel to the first long dimension and a first perpendicular bisector of the first long dimension is approximately collinear with a second perpendicular bisector of the second long dimension;
a third slotted aperture extending through the D-pad between the top surface and the bottom surface, the third slotted aperture having a third long dimension and a third short dimension; and
a fourth slotted aperture extending through the D-pad between the top surface and the bottom surface, the fourth slotted aperture having a fourth long dimension and a fourth short dimension, the fourth slotted aperture located such that the fourth long dimension is substantially parallel to the third long dimension and a third perpendicular bisector of the third long dimension is approximately collinear with a fourth perpendicular bisector of the fourth long dimension,
the third and fourth apertures further oriented such that a segment of the collinear perpendicular bisectors of the first and second long dimensions that lies between the first and second apertures has a first midpoint which is located at a point of coincidence approximately equal to a second midpoint of a segment of the collinear perpendicular bisectors of the third and fourth long dimensions that lies between the third and fourth apertures; and,

a D-pad clip attachable to the D-pad, the D-pad clip providing a lumen located adjacent to the top side of the D-pad at or near a location of the point of coincidence of the first and second midpoints and oriented approximately parallel to the top surface of the D-pad, the lumen configured to receive a carabiner therethrough;
a webbing connected to the D-pad by passing through the slotted apertures such that two separate sections of said webbing form a criss-crossing pattern near the point of coincidence and above the lumen; and,
a pivotable webbing retainer clip having an opening through which the criss-crossing pattern is threaded to retain the criss-crossing pattern between the webbing retainer clip and a first portion of the carabiner when the carabiner is inserted through the lumen of the D-pad clip, attachment clips of the webbing retainer clip, and is capturing the criss-crossing pattern of the two sections of webbing, the webbing retainer clip further configured to snap onto the carabiner.

5. The fall-protection safety apparatus of claim 4 , further comprising one or more additional webbing apertures.

6. The fall-protection safety apparatus of claim 4 , wherein the webbing is capable of being secured to another object.

7. The fall-protection safety apparatus of claim 4 , wherein the D-pad is curved to substantially conform to a corresponding portion of a human body.

8. The fall-protection safety apparatus of claim 7 , further comprising the carabiner inserted through the lumen and capturing the two sections of webbing at approximately the criss-crossing pattern of the webbing.

9. The fall-protection safety apparatus of claim 8 , further comprising an SRL attached to the carabiner.

10. The fall-protection safety apparatus of claim 4 , further comprising a D-ring attached to the D-pad.

11. A fall-protection safety apparatus for conne
