Definitions

  • the present invention relates to a safety harness to be used in fall protection systems for people working at heights.
  • Fall protection systems typically include a safety harness such as the one disclosed in EP 1803487 B1 .
  • This safety harness comprises belts for supporting the body of a person wearing the safety harness and an attachment point to which a securely anchored rope can be attached.
  • a worker who has fallen and lies on the ground or hangs suspended in the safety harness may have sustained injuries, and it is for this and other reasons important that the worker is rescued as quickly as possible.
  • Developing safety harnesses that facilitate the rescue of fallen workers remains an important area where further efforts are warranted.
  • a particular challenge here is to come up with designs that facilitate rescue operations in dark or low-light conditions.
  • a safety harness for fall protection.
  • the safety harness comprises a strap assembly adapted to pass around a body of a person wearing the safety harness, at least one front connector attached to the strap assembly so as to be located in front of a person wearing the safety harness and at least one back connector attached to the strap assembly so as to be located behind a person wearing the safety harness.
  • the front and back connectors are adapted to allow a person wearing the safety harness to be lifted, and at least one of the front and back connectors is a luminescent connector.
  • the front and back connectors are typically adapted to be connected to a respective safety wire which is securely anchored and intended to prevent the worker wearing the safety harness from falling or to arrest a fall.
  • the front and back connectors may also be used for connecting a wire that helps to position the worker while hanging.
  • rescue equipment such as a wire, cable, rope or similar, can be connected to the front connector and/or the back connector so that the worker can be brought to safety.
  • the risk of connecting the rescue equipment incorrectly to the safety harness when the rescue operation is undertaken in dark or low-light conditions is reduced by virtue of at least one of the front and back connectors being luminescent. Incorrectly connected rescue equipment may result in the worker being severely injured, even fatally so if for example the worker must be lifted by a helicopter.
  • the provision of a luminescent connector is thus a simple and economical way of substantially reducing the risk of injury during stressful situations in which mistakes are easily made.
  • the luminescent connector comprises a reflective coating and a luminescent coating covering the reflective coating.
  • the reflective coating may help to improve the visibility of the luminescent connector, especially if some of the luminescent coating is scratched off so that the reflective coating is exposed.
  • the luminescent connector comprises a luminescent coating and a translucent protective coating covering the luminescent coating.
  • the translucent protective coating helps to protect the luminescent coating from wear and environmental degradation.
  • the luminescent connector is a fluorescent connector.
  • a large number of fluorescent materials are inexpensive and readily commercially available.
  • Other types of luminescent connectors are of course conceivable.
  • the luminescent connector may for example be a phosphorescent connector.
  • the luminescent connector is ring-shaped.
  • ring-shaped is here meant that its general shape is similar to that of a ring. It should be noted that such a luminous connector may have more than one inner opening, or loop.
  • the general shape of the luminous connector may be circular, this is not necessary. The general shape can be that of an ellipse or a polygon, for instance.
  • a D-ring is ring-shaped in the sense the term is used in this text. Ring-shaped connectors are versatile in that they allow for easy and quick connection with many common types of rescue equipment, such as rescue wires provided with hooks.
  • the front and back connectors are luminescent connectors. This makes all of the front and back connectors easier to locate in dark or low-light conditions.
  • the strap assembly comprises two shoulder straps arranged to pass over a respective shoulder of a person wearing the safety harness and two leg straps arranged to encircle a respective leg of a person wearing the safety harness.
  • Such strap assemblies provide much support for the body and help to distribute fall arrest forces over a large portion of a wearer's body in the event of a fall.
  • FIGS 1 a and 1 b show a full-body safety harness 1 intended for fall protection system such as fall arrest systems and fall restraint systems.
  • the safety harness 1 has a strap assembly 2 which comprises several interconnected straps, alternatively referred to as belts or strings, made of a durable and strong material, for example polyester. How to arrange the straps to achieve a high level of wearer comfort and mobility and to make the safety harness 1 meet the specific needs of workers in different industries is considered to be known by a person skilled in the art. This will therefore not be discussed in detail herein. In short, however, it may be noted that in this example the strap assembly 2 includes two shoulder straps 2a and two leg straps 2b.
  • Each shoulder strap 2a extends from the chest, over a shoulder and to the back of a person wearing the safety harness 1, and the leg straps 2b fit around a respective thigh.
  • the straps are interconnected via buckles 3, some of which allow for adjusting the strap lengths so that the safety harness 1 can be made to fit tightly around the body of a user.
  • Attached to the shoulder straps 2a is a pad 4 for supporting the back of a person wearing the safety harness 1.
  • One front connector 5 and one back connector 6 are attached to the strap assembly 2.
  • the front connector 5 and the back connector 6 are luminous connectors (which will be further described below with reference to Figures 2 and 3 ).
  • Another example of a safety harness 1 may have only one luminous connector, in which case either the front connector 5 or the back connector 6 is a luminous connector.
  • the front connector 5 is attached to straps on the front side of the safety harness 1, approximately in level with the chest of a wearer standing upright.
  • the back connector 6 is attached to straps on the back side of the safety harness 1, approximately in level with the upper portion of the back of a wearer standing upright.
  • both of the front and back connectors 5, 6 are D-rings.
  • the front and back connectors 5, 6 may or may not be D-rings, and it may or may not be the case that the front and back connectors 5, 6 have the same shape.
  • the front and back connectors 5, 6 in the illustrated example are attached to the strap assembly 2 by straps passing through their inner openings.
  • FIG 2 shows a luminous connector 10 which is similar to the front and back connectors 5, 6 in Figures 1 a and 1 b.
  • the luminous connector 10 is not a D-ring but a circular ring with one inner opening.
  • the luminous connector 10 has a body 11 that is covered by a luminous coating 12 arranged directly on the body 11.
  • the luminescent coating 12 covers the entire body 11.
  • the body 11 of the luminescent connector 10 in this example is a solid torus the outer surface of which is completely covered by the luminescent coating 12.
  • the body 10 can be made of a metal, such as steel.
  • the luminous coating 12 can be a layer of a flourescent or phosphorescent material, such as a layer of a flourescent polyvinyl chloride (PVC) or some other flourescent plastic material.
  • the luminescent coating 12 may be applied to the body 11 using for example a moulding process.
  • Figure 3 shows a luminous connector 10' which is similar to the luminous connector 10 in Figure 2 except for a reflective coating 13 arranged between the body 11 and the luminous coating 12 as seen in the radial direction.
  • the reflective coating 13 can for example be a layer of white paint.
  • Figure 4 shows a luminous connector 10" which is similar to the luminous connectors 10 in Figure 2 except for a translucent protective coating 14 that covers the luminous coating 12.
  • the translucent protective coating 14 can for example be made of a clear plastic material.
  • the translucent protective coating 14 may comprise a wavelength converting material adapted to wavelength convert at least some of the light emitted by the luminescent coating 12 to a different wavelength, in the visible or non-visible spectrum, something which may make the lumiescent connetor 10" easier to locate during rescue operations.
  • the wavelength converting material may for example be phosphor or a quantum dot material.
  • the luminnescent connector 10" may also comprise a reflective coating 13 arranged between the body 11 and the luminous coating 12.
  • the present invention may be a chest harness or a body belt rather than a full-body harness like the one described above.
  • any reference signs placed between parentheses shall not be construed as limiting to the claim.
  • the word “comprising” does not exclude the presence of other elements than those listed in the claim.
  • the word “a” or “an” preceding an element does not exclude the presence of a plurality of such elements.
