[0030] Figure 14 shows the harness of figure 9, in use. DESCRIPTION OF THE EMBODIMENTS [0031] In figures 1 to 3, reference numeral 10 generally indicates an embodiment of a support device for a fall arrest harness. [0032] The support device 10 includes a dorsal member 12. The dorsal member 12 is configured for arrangement on a dorsal region of a wearer and for operative engagement with a safety harness. More particularly, the dorsal member 12 is dimensioned to overlie the thoracic spine of an average or generic wearer. [0033] A neck support member 14 extends from an upper portion 16 of the dorsal member 12 and is configured to support a neck of the wearer when the dorsal member 12 is arranged on the dorsal region of the wearer. More particularly, the neck support member 14 is configured to overlie the cervical spine of the average or generic wearer. [0034] The dorsal member 12 and neck support member 14 are in the form of a unitary construction. For example, the dorsal and neck support members 12, 14 may be moulded, cast, printed or machined. [0035] As can be seen in figure 3, the dorsal member 12 has an arcuate profile to correspond to a generic side profile of the thoracic spine of the wearer. Thus, the dorsal member 12 curves outwardly from the upper portion 16 to an intermediate portion 20 about one third to a half of a vertical length of the dorsal member 12 away from the shoulder region 16 and then inwards to a lower portion 18 of the dorsal member 12.

5 [0036] The dorsal member 12 is waisted, with a narrowest width at the intermediate region 20. [0037] The upper portion 16 includes two upper harness engagement zones 22.1, 22.2 that are spaced and positioned to overlie respective scapula regions of the wearer. In this embodiment, the zones 22.1, 22.2 each define slots 24.1, 24.2 through which straps of a fall arrest harness can be threaded. [0038] The lower portion 18 includes two lower harness engagement zones 26.1, 26.2 that are spaced and positioned to overlie a lower region of the ribcage. The lower portion 18 is bifurcated so that the zones 26 are separated by an arcuate or curved recess. In this embodiment, the zones 26.1, 26.2 each define slots 28.1, 28.2, respectively, through which the straps can be threaded. [0039] The support device 10 can have a range of dimensions. However, it will be appreciated that the support device 10 can have dimensions that would suit the average wearer. For example, an overall vertical height or length of the member 10 can be between about 380 mm and 450 mm, for example, between about 410 mm and 420 mm. An overall width of the device 10 at the upper harness engagement zones 22 can be between about 230 mm and 260 mm, for example, between about 240 mm and 250 mm. An overall width of the device 10 at the lower harness engagement zones 26 can be between about 225 mm and 255 mm, for example, between about 230 mm and 250 mm. [0040] The neck support member 14 extends backwardly from the upper portion 16 of the dorsal member 12. The neck support member 14 extends backwardly between about 30 mm and 40 mm. Thus, when the head and neck are supported by the support member 14, the head is tilted slightly backwardly to ensure that the wearer's breathing passages remain open. In this position, the neck support member 14 serves to cradle the neck of the wearer. [0041] It will be appreciated that the neck support member 14 serves to support the head and neck in a fall arrest event. This can serve to reduce or neutralise whiplash or hyperextension of the neck as result of the fall. Conventional safety harnesses are not provided with some form of neck support. As a result, a fall arrest event where the wearer is supported in a partially reclined or recumbent position can result in severe 6 injury to the spinal region of the neck and even the upper back. A safety harness provided with the support device 10 can alleviate this problem. [0042] Furthermore, the backward tilting of the head as a result of the configuration of the dorsal member 12 and the neck support member 14 can serve to keep the air passages of the wearer open in the event that the wearer happens to lose consciousness as a result of the fall. With loss of consciousness and without the support device 10, the wearer's head can over-extend backwardly resulting in blockage of the airways and, as a result, possibly death. [0043] From the front, the neck support member 14 has a narrowed collar 30. The support member 14 tapers outwardly from the collar 30 to a cranial portion 32. The cranial portion 32 has a downwardly curved upper edge 34 to accommodate the back of the wearer's head. Opposed sides of the cranial portion 32 are rounded. [0044] The neck support member 14 is also curved in a horizontal plane with a horizontally outermost point in general vertical alignment with a horizontally outermost point of the dorsal member 12. [0045] The curvature of the neck support member 14, in the horizontal plane, serves to retain the head against excessive movement from side to side subsequent to a fall arrest event. In addition to hyperextension, such excessive side to side movement could also cause injury in the absence of the curvature in the horizontal plane. That curvature also serves to retain the head in a comfortable forward facing position so that the wearer can rest his or her head without excessive swivelling or tilting. [0046] The neck support member 14 is dimensioned so as not to interfere with normal movement of the head while the wearer works. In other words, the backwardly angled orientation and the height or length of the neck support member 14 are appropriately selected so as to allow normal movement of the head without interference. [0047] An overall depth of the support device 10 is between about 65 mm and 75 mm. [0048] The support device 10 has a consistent thickness of between about 3 mm and 7 mm.

7 [0049] The slots 24, 28 can be in the form of diagonally opposed pairs, one pair being 24.1 and 28.1 and the other pair being 24.2 and 28.2. The slots 24.1, 28.1 are oriented to be generally orthogonal to one of the straps. Likewise, the slots 24.2, 28.2 are oriented to be generally orthogonal to another of the straps. Thus, the straps can cross and overlie each other. In such a position, the straps can serve to enhance the structural integrity of the support device 10. [0050] Each slot 24, 28 has a length and width to accommodate conventional straps or webbing that would be used in a conventional fall arrest harness. Alternatively, the slots 24, 28 have a length and width to accommodate straps or webbing that might be used in a customised harness suited for the support device 10. [0051] The dorsal member 12 is ventilated for comfort. Ventilation of the dorsal member 12 is achieved by a plurality of openings 36 defined in the dorsal member 12. As can be seen, the openings 36 are arrayed to define paths 38 for the straps or webbing of the fall arrest harness. The openings 36 also serve to reduce the amount of material used for the fabrication of the support device 10 while maintaining the integrity of the device 10. [0052] In this example, the support device 10 is fabricated from a plastics material. For example, the support device 10 can be fabricated from polypropylene or similar material. However, the inventor envisages that the support device 10 can be fabricated from various materials that may be suited for purpose. [0053] The support device 10 provides a mechanism whereby the pressure exerted by the straps of the fall arrest harness are distributed by the dorsal member 12. Thus, the dorsal area of the user or wearer can be protected from potential damage by the straps in a fall arrest situation. Furthermore, the neck support member 14 is configured to prevent whiplash or neck hyperextension in such a situation. [0054] In addition, the support device 10 can provide a level of comfort during normal working conditions. For example, a wearer can simply lean back and relax without the straps exerting pressure directly on the wearer's body which could cause discomfort over time. Also, the wearer can relax his or her head with the support member 14 providing head and neck support, while the neck is cradled.

8 [0055] Thus, the material from which the support device 10 is fabricated is selected to provide sufficient rigidity to perform the functions described above. It follows that, in some cases, the support device 10 can be fabricated from a material that is generally inflexible. In other cases, the support device 10 can be fabricated from a material that has a predetermined extent of give or flexibility. Such give or flexibility can permit the support device 10 to absorb a certain amount of shock in the event of a fall arrest situation. Furthermore, the material can be selected so that the neck support member 14 can flex to a certain degree with respect to the dorsal member 12. This can also serve to absorb impact which would otherwise be transmitted to the wearer's head and neck. [0056] In addition to provision for straps, the slots 24, 28 can also be used to connect a utility pack to a safety harness. For example, the slots 24, 28 can be used to connect a utility pack such as a hydration pack to the safety harness. Alternatively, the utility pack can be connected or mounted on the upper harness engagement zones 22. [0057] As can be seen from the drawings, a side profile (figure 3) of the support device 10 generally matches a spinal profile of a generic or average wearer. As such, the support device 10 facilitates healthy spinal ergonomics both during a fall arrest event and during normal day-to-day work. [0058] Furthermore, the support device 10 provides a suitable platform for the bracing of a wearer's head in order to minimise or prevent exacerbation of any existing head, neck or spinal injury. For example, the wearer's head could be bandaged to the neck support member 14. [0059] In figure 4, reference numeral 40 generally indicates an embodiment of a support device. With reference to the preceding drawings, like reference numerals refer to like parts, unless otherwise specified. The use of common reference numerals is not intended to limit the scope of the appended claims and is for the purpose of convenience only. Furthermore, components or characteristics of the support device 10 are interchangeable with components or characteristics of the support device 40, if possible and/or practicable. [0060] The support device 40 includes a padding or cushioning member 42. The member 42 is fastened to an inner or front surface 44 (figures 1 to 3) of the dorsal member 12.

9 [0061] The member 42 has a dorsal portion 46 that is larger than the dorsal member 12 so that it extends past edges of the dorsal member 12. [0062] A neck pocket 48 is arranged on the dorsal portion 46. The neck pocket 48 is configured so that the neck support member 14 can be received in the neck pocket 48. [0063] The member 42 has two pairs of upper and lower diagonally opposite legs or arms 50.1, 52.1 and 50.2, 52.2. The arms 50.1, 50.2 are positioned to extend from the upper engagement zones 22.1, 22.2, respectively. The arms 52.1, 52.2 are positioned to extend from the lower engagement zones 26.1, 26.2, respectively. [0064] The padding member 42 and the neck pocket 48 are of a suitable padding material. An example of such a material is an expanded plastics material, woven or non woven textile material, or the like. [0065] The support device 40 includes webbing 54 that is fastened to a back surface 56 of the dorsal member 12. This attachment can take different forms. For example, the attachment can be by way of press studs, adhesive, Velcro TM or any other form of suitable fastening, permanent or temporary. [0066] The webbing 54 includes two straps 58.1, 58.2 that are fastened to the dorsal member 12 to overlie the paths 38. In this example, the straps 58 are received through the slots 24, 28. Fastening strips 60 are stitched to the straps 58, at each engagement zone 22, 26 and on each side of the associated slot 24, 28 to secure the straps to the dorsal member 12. [0067] The straps 58 can be of webbing material of the type that is used in safety harnesses. The strips 60 can also be of such a webbing material. [0068] Loop connectors 62.1, 62.2 are fastened to respective upper ends of the straps 58. Loop connectors 63.1, 63.2 are fastened to respective lower ends of the straps 58. The loop connectors 62 allow straps of a fall arrest harness to be connected to the straps 58 so that the fall arrest harness can be connected to the support device 40. Thus, the loop connectors 62, 63 can be conventional loop connectors. [0069] The support device 40 is suited for use with a fall arrest harness that does not have straps that are sufficiently long to extend across the dorsal member 12.

10 [0070] The inventor envisages that the straps 58 need not cross over, as shown in the drawings. Instead, the straps could extend parallel to each other between appropriately oriented slots or some other fastening arrangement. [0071] In figure 5, reference numeral 70 generally indicates an embodiment of a support device for a fall arrest harness. With reference to the preceding drawings, like reference numerals refer to like parts, unless otherwise specified. The use of common reference numerals is not intended to limit the scope of the appended claims and is for the purpose of convenience only. [0072] In this example, connectors, such as stud connectors 72 are arranged on the strips 60 and the straps 58 so that the strips 60 can be clipped to, or unclipped from, the straps 58. The connectors 72 can also be configured to attach the strips 60 to the straps 58 in a permanent manner. [0073] The inventor envisages that a large number of different types of connection or fastening systems can be used to fasten the strips 60 to the straps 58. These could include hook-and-eye fastening arrangements, such as Velcro TM, adhesive or various hook attachments. [0074] In figure 6, reference numeral 80 generally indicates an embodiment of a fall arrest harness using the support device 10 (figure 6). In figure 7, reference numeral 100 generally indicates an embodiment of a fall arrest harness using either of the support devices 40, 70. With reference to the preceding drawings, like reference numerals refer to like parts, unless otherwise specified. The use of common reference numerals is not intended to limit the scope of the appended claims and is for the purpose of convenience only. Furthermore, components or characteristics of the embodiments are interchangeable, if possible and/or practicable. [0075] The harness 80, 100 includes a waist band 82. The waist band 82 includes a belt webbing 84 fastened to belt padding 86. [0076] The harness 80, 100 has two straps 88.1, 88.2 configured for operative engagement with the wearer's shoulders. In figure 6, the straps 88.1 pass through the slots 24.1, 28.1 and 24.2, 28.2, respectively and overlie the paths 38, in the manner described above.

11 [0077] In the harness 80, a pair of tags 90.1, 90.2 is stitched to the belt webbing 84. Loop connectors 92.1, 92.2 are fastened to respective tags 90.1, 90.2. Ends of the straps 88.1, 88.2 are fastened to respective loop connectors 92.1, 92.2 thereby securing the support device 10 to the harness 80. [0078] In this example, the cushioning member 42 is arranged on the inner surface 44 of the dorsal member 12. [0079] In the harness 100, the straps 88.1, 88.2 are shorter and are connected to the loops 62.1, 62.2 (figure 5), respectively. [0080] A pair of tags 102.1, 102.2 are stitched to the belt webbing 84. The tag 102.1 is connected to the connector 63.1, and the tag 102.2 is connected to the connector 63.2. [0081] Figure 8 shows a front view of either of the harnesses 80, 100. [0082] The harness 80, 100 includes a pair of thigh straps 104.1, 104.2 that can be fastened about respective thighs 106.1, 106.2 of the wearer. The thigh straps 104.1, 104.2 include thigh strap webbing 108.1, 108.2 arranged on padding 110.1, 110.2. Adjustable buckles 112.1, 112.2 are arranged on the webbing 108.1, 108.2 to adjust the tightness of the thigh straps 104.1, 104.2. [0083] Connecting straps 114.1, 114.2 interconnect the straps 104.1, 104.2 and the belt webbing 84 behind the thighs 106, as can be seen in figures 6 or 7. Connecting straps 116.1, 116.2 interconnect the straps 104.1, 104.2 and the belt webbing 84 in front of the thighs 106. [0084] The harness 80, 100 includes a thigh seat arrangement 118 that is configured to extend across the thighs 106 between the knees and buttocks of the wearer and at least partially about outer sides of the thighs 106. [0085] The thigh seat arrangement 118 includes thigh seat padding 120 and thigh seat webbing 122 that overlies and extends past the padding 120. [0086] The belt webbing 84 is configured to extend about a waist portion 124 of the wearer. The belt padding 86 extends partially about the waist portion 124 to define a frontal gap 128.

12 [0087] Adjustment buckles 126 are arranged on the belt webbing 84 so that a tightness and fit of the waist band 82 can be adjusted. [0088] Guide loops 132.1, 132.2 are arranged on the thigh straps 104.1, 104.2, respectively. The webbing 122 threads through the loops 132.1, 132.2. [0089] Instead of the guide loops 132.1, 132.2, the thigh strap webbing 108 can be stitched to the padding 110 to define an angled passageway 152 to accommodate the thigh seat webbing 122. Detail of this alternative arrangement is shown in figure 10. With reference to the preceding drawings, like reference numerals refer to like parts, unless otherwise specified. The use of common reference numerals is not intended to limit the scope of the appended claims and is for the purpose of convenience only. [0090] An adjustment buckle 154 is arranged in the thigh seat webbing 122 so that a wearer can adjust the length of the webbing 122. [0091] The harness 80, 100 includes a recumbency mechanism 129. The recumbency mechanism 129 is operatively engaged with the waist band 82. The recumbency mechanism 129 is connectable to a tether so that, in a fall arrest situation, the recumbency mechanism operates to place the wearer in at least a partially recumbent or seated position. [0092] Detail of the recumbency mechanism 129 is shown in figures 11 and 12. [0093] The mechanism 129 includes a guide strap 130 that is fastened to the belt webbing 84 at its ends. Ends of the webbing 122 are fastened together and threaded between the guide strap 130 and the belt webbing 84. A tethering device, such as a D ring 134 is connected to the webbing 122. Thus, in a fall arrest situation, the webbing 122 is at least partially drawn between the guide strap 130 and the belt webbing 84. At the same time, the webbing 122 slides with respect to the guide loops 132.1, 132.2, so drawing the thighs 106 upwardly while the wearer is supported at the waist portion 124. [0094] The guide strap 130 can be sewn or stitched over or under the respective connecting straps 116. In this example, the guide strap 130 is sewn beneath the respective connecting straps 116. [0095] The straps 88.1, 88.2 of the harness 80, 100 extend over the wearer's shoulders and down to the belt webbing 84 and are stitched to the belt webbing 84.

13 Thus, as the thigh strap webbing 108.1, 108.2 acts to draw the thighs 106 upwardly, the straps 88 serve to support the wearer in at least a partially recumbent or seated position. More particularly, in the fall arrest situation, the belt webbing 84 is drawn upwardly away from the abdominal region of the wearer. This serves to set up tension in the straps 88 so that the wearer can be supported in the partially recumbent or seated position. [0096] A lanyard connector in the form of a D-ring 138 is fastened to the belt webbing 84 with suitable connecting straps 136. The D-ring 138 is used for a work positioning lanyard. However, in the event that such a lanyard or rope is not used, the safety tether or lanyard is to be connected to both the D-rings 134, 138. [0097] The harness 80, 100 includes a chest strap 150 that interconnects the straps 88 across a thoracic region of the wearer. An adjustment buckle 152 is arranged on the chest strap 150 to allow the chest strap 150 to be adjusted or released. [0098] A further lanyard or rope connector, in the form of a D-ring 154 is connected to the chest strap 150. [0099] Auxiliary connectors in the form of D-rings 156 are connected to the belt webbing 84. [0100] In figure 9, reference numeral 140 generally indicates an embodiment of a fall arrest harness. With reference to the other drawings, like reference numerals refer to like parts, unless otherwise specified. The use of common reference numerals is not intended to limit the scope of the appended claims and is for the purpose of convenience only. [0101] The shoulder straps 88.1, 88.2 of the harness 140 are defined by a single strap 88 that extends over the wearer's shoulders and engages a work positioning connector in the form of a D-ring 142. In turn, the D-ring 142 is connected to a further work positioning connector in the form of a further D-ring 144 with a suitable strap 146. In turn, the D-ring 144 is connected to the belt webbing 84. Again, this connection is by means of a suitable strap 148. [0102] The D-rings 142, 144 allow connection to a work positioning lanyard or rope in two positions. For example, the shoulder straps 88 and the straps 146 are configured so that one point of connection is sternal and the other is abdominal.

14 [0103] Furthermore, in a fall arrest situation, resultant movement of the belt webbing 84 can set up tension in the straps 146, 148 so that the wearer can be supported in at least a partially recumbent or seated position. [0104] In figures 12 and 13, there is shown a backup device that includes a guide loop 156 stitched to the belt webbing 84, below the guide strap 130. With reference to the preceding drawings, like reference numerals refer to like parts, unless otherwise specified. The use of common reference numerals is not intended to limit the scope of the appended claims and is for the purpose of convenience only. [0105] The webbing 122 passes through the guide loop 156 and between the guide strap 130 and the belt webbing 84. The guide loop 156 is dimensioned so that the D ring 138 is unable to pass through the guide loop 156. The purpose of this is to serve as a backup in case the guide strip 130 fails. Should that occur, the D ring 138 is caught by the loop 156, ensuring retention of the wearer in the at least partially recumbent or seated position. [0106] Operation of the harness 140 is shown in figure 14. [0107] As can be seen in figure 11, the thigh seat webbing 122 is drawn partially between the guide strip 130 and the belt webbing 84. The webbing 122 thus serves to support the wearer's thighs 106.1, 106.2 generally horizontally. At the same time, a resultant tension set up in the straps 88 via the connecting straps 146, 148. Thus, the wearer is supported in a partially recumbent or seated position.

Variations (e.g., modifications and/or enhancements) of one or more embodiments described herein might become apparent to those of ordinary skill in the art upon reading this application. The inventors expect skilled artisans to employ such variations as appropriate, and the inventors intend for the claimed subject matter to be practiced other than as specifically described herein. Accordingly, as permitted by law, the claimed subject matter includes and covers all equivalents of the claimed subject matter and all improvements to the claimed subject matter. Moreover, every combination of the above described elements, activities, and all possible variations thereof are encompassed by the claimed subject matter unless otherwise clearly indicated herein, clearly and specifically disclaimed, or otherwise clearly contradicted by context. [0111] The use of any and all examples, or exemplary language (e.g., "such as") provided herein, is intended merely to better illuminate one or more embodiments and does not pose a limitation on the scope of any claimed subject matter unless otherwise stated. No language in the specification should be construed as indicating any non claimed subject matter as essential to the practice of the claimed subject matter. [0112] The use of words that indicate orientation or direction of travel is not to be considered limiting. Thus, words such as "front", "back", "rear", "side", "up", down", "upper", "lower", "top", "bottom", "forwards", "backwards", "towards", "distal", "proximal", "in", "out" and synonyms, antonyms and derivatives thereof have been selected for convenience only, unless the context indicates otherwise. The inventor envisages that various exemplary embodiments of the claimed subject matter can be supplied in any particular orientation and the claimed subject matter is intended to include such orientations. [0113] Thus, regardless of the content of any portion (e.g., title, field, background, summary, description, abstract, drawing figure, etc.) of this application, unless clearly specified to the contrary, such as via explicit definition, assertion, or argument, or clearly contradicted by context, with respect to any claim, whether of this application and/or any 16 claim of any application claiming priority hereto, and whether originally presented or otherwise: a. there is no requirement for the inclusion of any particular described or illustrated characteristic, function, activity, or element, any particular sequence of activities, or any particular interrelationship of elements; b. no characteristic, function, activity, or element is "essential"; c. any elements can be integrated, segregated, and/or duplicated; d. any activity can be repeated, any activity can be performed by multiple entities, and/or any activity can be performed in multiple jurisdictions; and e. any activity or element can be specifically excluded, the sequence of activities can vary, and/or the interrelationship of elements can vary. [0114] The use of the terms "a", "an", "said", "the", and/or similar referents in the context of describing various embodiments (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. The terms "comprising," "having," "including," and "containing" are to be construed as open-ended terms (i.e., meaning "including, but not limited to,") unless otherwise noted. [0115] Moreover, when any number or range is described herein, unless clearly stated otherwise, that number or range is approximate. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value and each separate sub-range defined by such separate values is incorporated into the specification as if it were individually recited herein. For example, if a range of 1 to 10 is described, that range includes all values there between, such as for example, 1.1, 2.5, 3.335, 5, 6.179, 8.9999, etc., and includes all sub ranges there between, such as for example, 1 to 3.65, 2.8 to 8.14, 1.93 to 9, etc. [0116] Accordingly, every portion (e.g., title, field, background, summary, description, abstract, drawing figure, etc.) of this application, other than the claims themselves, is to be regarded as illustrative in nature, and not as restrictive, and the 17 scope of subject matter protected by any patent that issues based on this application is defined only by the claims of that patent.
