Description

Title of the invention: UNIVERSAL HARNESS FOR WORKING AT HEIGHT, CLIMBING OR MEDICAL REHABILITATION technical field

[0001] The present invention relates to the general technical field of sports equipment and in particular to equipment for practicing climbing or for working at height or for medical rehabilitation or the transfer / lifting of patients.

[0002] The invention relates, for example, to a universal safety harness enabling athletes to avoid falls while climbing walls. The invention also relates to a universal safety harness adapted for working at height. The invention further relates to a safety harness adapted for people with disabilities or reduced mobility, for example, to allow them to discover and practice climbing safely. The invention also relates, for example, to a safety harness for supporting a patient during certain medical rehabilitation or transfer exercises.

[0003] In the following, the term “user” or “carrier” refers to the person equipped and / or suspended by a safety harness, for example for work at height, for climbing or for medical rehabilitation sessions or patient transfers. Previous technique

[0004] Safety harnesses are known particularly in the context of rock climbing and professional activities requiring work at height. During such activities, it is essential to secure the person working at height in the event of an accidental fall. Such a safety harness, secured by a rope or strap attached to a fixed point, prevents serious or fatal consequences in the event of a fall.

[0005] Safety harnesses known and used in sports, particularly climbing, have a major drawback: they are not suitable for people with disabilities, such as wheelchair users with limited or reduced use of their lower or upper limbs. It is therefore difficult for such people to discover or practice climbing safely. Presentation of the invention

[0006] The object of the invention is therefore to overcome the drawbacks of the prior art by proposing a new safety harness whose use is facilitated. and simplified, in particular for people with reduced mobility or disabilities.

[0007] Another object of the invention aims to provide a safety harness that adapts to multiple deficiencies of the arms and / or legs of users.

[0008] Another object of the invention aims to provide a safety harness with increased ease of use, particularly for people with reduced mobility, people with disabilities, overweight or obese people, without altering its effectiveness in the event of a fall.

[0009] Another object of the invention aims to provide a safety harness that allows space to be freed up in front of the wearer of said harness and does not hinder his movements, in particular when handling potentially dangerous tools or other devices at height during work at height.

[0010] The objects assigned to the invention are reached using a safety harness for working at height, climbing or medical rehabilitation, comprising: - a back panel associated with two back straps, each of which has an upper part extending to form shoulder straps and a lower part extending to form thigh straps, - the thigh straps, each comprising a male part of a snap-on buckle whose position is adjustable on the corresponding thigh strap, - the shoulder straps extending to form adjustable-length chest straps, one end of which includes a female part of the snap buckle, - each end portion passing through a split in the corresponding lower part, said split being located upstream of the thigh strap, allowing the snap buckle to close when the thigh strap extends around the user's thigh, - a sternal bridge with a side-release buckle for connecting the pectoral straps, - a connecting harness linking the thigh straps, and - at least one suspension loop placed on each shoulder strap.

[0011] According to one embodiment, the sternal bridge comprises a ring providing a sternal attachment point.

[0012] According to one embodiment, each strap has three suspension loops distributed on said straps to constitute on each strap a front attachment point, a central attachment point and a rear attachment point, which allow the wearer suspended by said safety harness to achieve, respectively, a forward inclination, a near-perfect verticality and a backward inclination.

[0013] According to one embodiment, the suspension loops are made with strap loops sewn onto the straps.

[0014] According to one embodiment, the safety harness comprises a rigid spreader bar, substantially in the shape of an inverted U, associated with at least one suspension strap, said spreader bar being intended to extend around and away from the head of the wearer of said safety harness, approximately in a frontal plane of said wearer and to constrain the positioning of the suspension strap along said spreader bar, each end of the suspension strap being connected to a suspension loop of a shoulder strap, the central part of the suspension strap being provided with a central attachment ring at the top of the spreader bar.

[0015] According to another embodiment, the safety harness comprises a rigid spreader bar, substantially in the shape of an inverted U, associated with at least two suspension straps, said spreader bar being intended to extend around and away from the head of the wearer of said safety harness, approximately in a frontal plane of the wearer and to constrain the positioning of the suspension straps along said spreader bar, a first end of each suspension strap being connected to a suspension loop of a shoulder strap, the second end of each suspension strap being provided with a specific central attachment ring, said central attachment rings being positioned at the top of the spreader bar.

[0016] According to one embodiment, the safety harness includes a support strap mounted at the bottom on the back panel and connecting the back straps together, the support strap having an adjustment buckle to modify the spacing between the back straps.

[0017] According to one embodiment, the support strap includes fixing clips to establish a connection with non-elastic leg straps, adjustable in length and connected to the thigh straps, to adapt said safety harness to the morphology and orientation of the wearer's pelvis.

[0018] According to one embodiment, the shoulder straps and / or thigh straps and / or chest straps have, on the wearer's side, removable and adjustable foam portions to improve user comfort.

[0019] According to one embodiment, each lower part, at the level of the strap split, has a semi-rigid gripping handle, positioned on the outer lateral side of each thigh and allowing a third person to lift the person wearing said safety harness out of his chair or seat.

[0020] According to one embodiment, the back straps overlap above the back panel, so as to obtain an increased spacing between the upper part of said back straps and to form an additional safety attachment point.

[0021] According to one embodiment, the safety harness includes a dorsal fall arrest loop, added by overstitching on the overlap area of ​​the dorsal straps.

[0022] According to one embodiment, the back plate can slide along said back straps.

[0023] According to one embodiment, each end portion, passing through a split in the corresponding lower part, also has a split strap portion so as to create an interlacing between the corresponding split parts and allow limited sliding of the end portion on the lower part.

[0024] The objects assigned to the invention are also achieved using a safety assembly for climbing or working at height comprising a safety harness as presented above, a support and traction system connected to the suspension loops of the safety harness via a rope or strap, so as to secure the person equipped with said safety harness and providing a traction force so as to reduce the effort to be made by the user when climbing a climbing wall.

[0025] According to one embodiment, the support and traction system is automated and includes a calculator to determine traction assistance to be provided based on the traction effort provided by the user during their movements.

[0026] The safety harness according to the invention has the significant advantage of being particularly suitable for people who, for example, use a wheelchair or whose mobility, for example, in their lower limbs, is reduced. The safety harness can advantageously be put on simply and quickly while seated. Indeed, the safety harness allows a person remaining seated, for example in a wheelchair, to put on the harness easily without assistance from another person.

[0027] The harness according to the invention facilitates standing upright and provides substantial support to the postural muscles. This prevents the knees from rubbing against the wall. The safety harness according to the invention adapts perfectly to various constraints related to more or less pronounced disabilities.

[0028] Thanks to the safety harness according to the invention, a sporting activity such as climbing is made accessible to a public for whom this was not previously conceivable

[0029] The harness according to the invention also allows for self-adjustment to its wearer and for fine adjustments to be made, so as to adapt to the particular morphology of its wearer and, where appropriate, to the specificities of his disability.

[0030] Another advantage of the safety harness according to the invention lies in the stability it provides to its user, suspended in mid-air. The user, lacking the use of their lower limbs or, where applicable, only having the use of their lower limbs, can benefit from this. with reduced use of his upper limbs, can then very easily move on a climbing wall while maintaining full mobility of the upper limbs.

[0031] In the field of working at height, an advantage of the safety harness according to the invention lies in the absence of a chest or ventral safety rope or strap, thus completely freeing up the workspace at height in front of the wearer of said harness. The movements of their arms and, where applicable, the handling of potentially dangerous tools is therefore greatly facilitated and done in complete safety. Similarly

[0032] Another advantage of the safety harness according to the invention lies in the use of a spreader bar integrated into the harness, which, in certain cases—particularly when using a spreader bar with two separate suspension straps—eliminates the need for a second safety rope connected to a dorsal loop. This frees up the wearer's back for carrying a backpack or tools. This advantage can also be achieved by attaching the second safety rope to a suspension loop on a shoulder strap not used by the spreader bar.

[0033] Another advantage of the safety harness according to the invention lies in its association with an automated traction system connected to the harness via a rope, steel cable, or webbing. Such a traction system provides assistance to the wearer by applying traction to the harness, thereby reducing the effort required to climb a wall. This system enables a person with a disability to improve their physical condition, even with partial impairment of the arms and / or legs.

[0034] The safety harness according to the invention allows for optimal verticality for the wearer and consequently an optimal distance from a climbing wall. Furthermore, the safety harness is suitable for activities with or without the wearer's feet. Brief description of the drawings

[0049] Structurally and functionally identical or similar elements, present on several distinct figures, are assigned the same numeric or alphanumeric reference.

[0050] Fig. 1 is a rear view of an example of an embodiment of a safety harness 1 intended for the practice of climbing.

[0051] The safety harness 1 comprises a back panel 2 associated with two back straps 3 and 4. The back straps 3 and 4 cross in an X and each has an upper part extending to form shoulder straps 5 and 6 and a lower part extending to form leg straps 7 and 8. Advantageously, the back panel 2 can slide along said back straps 3 and 4.

[0052] The thigh straps 7 and 8 each have a male part 9a of a snap-on buckle whose position is adjustable on the corresponding thigh straps 8, 7.

[0053] The straps 5 and 6 extend to form chest straps 10 and 11 of adjustable length, an end portion of which includes a female part 9b of the snap buckle.

[0054] Each end portion passes through a split 3a, 4a of the corresponding lower part. The split 3a and 4a being located respectively upstream of the thigh strap 7 and 8, allowing the snap buckle to close, by cooperation of the male parts 9a and the female parts 9b, when the thigh strap 7, 8 extends around the user's thigh.

[0055] The safety harness 1 also includes a sternal bridge 12 having a ring 13 and a side release buckle 14 for connecting the pectoral straps 10 and 11.

[0056] According to one embodiment, the sternal bridge 12 includes a ring 13 providing a sternal attachment point.

[0057] The safety harness 1 advantageously includes a connecting saddle 15 linking the thigh straps 7 and 8.

[0058] The safety harness 1 also includes at least one suspension ring 16 disposed on each shoulder strap 5, 6. The suspension ring 16 located on each shoulder strap 5, 6 allows the safety harness 1 to be attached to a support and / or traction system via a rope, wire rope or strap.

[0059] The shoulder straps 5, 6 and / or the thigh straps 7, 8 and / or the chest straps 10, 11 advantageously include removable foam portions 17. The position of the foam portions 17 is preferably adjustable to improve user comfort. The foam portions located under the shoulder straps 5 and 6, for example, form extensions of the back panel 2.

[0060] By way of example, a double loop system 18, known as such, allows the pectoral straps 10, 11 to be lengthened or shortened.

[0061] According to an example embodiment of the safety harness 1, each lower part, at the point where the straps split 3a and 4a, has a semi-rigid gripping handle 20. The gripping handle 20 is positioned on the outer lateral side of each thigh and allows, for example, a third person to lift the person wearing said safety harness 1 out of their chair or seat.

[0062] According to one embodiment, the dorsal straps 3 and 4 cross above the dorsal breastplate 2. The latter can advantageously slide along said dorsal straps 3, 4. Reference may be made in particular to [Fig. 1] and 2.

[0063] According to one embodiment, each end portion of the pectoral straps 10, 11, passing through a split 3a, 4a of the corresponding lower part, also has a split strap portion 10a, 1la so as to create an interlacing between the corresponding split portions 3a-10a and 4a-1la. Such a configuration allows limited sliding of the end portion on the lower part on the one hand and maintenance in a position near the thigh of the user, the said end part on the other hand, one can for example refer to [Fig.4].

[0064] Fig. 5 is an enlarged detail illustrating the sternal bridge 12 of an example embodiment of a sternal bridge of the safety harness 1.

[0065] Fig. 6 is an enlarged detail illustrating the mounting of the foam portions 17 of the connecting bridge 15 of the leg straps 7, 8 of the safety harness 1. The foam portions 17 are, for example, mounted slidingly on the leg straps 7, 8 by means of VELCRO systems 17a.

[0066] Figure 7 is a rear view of another embodiment of a safety harness 1. The back straps 3 and 4 overlap above the back panel 2, so as to obtain an increased distance between the upper parts of said back straps 3 and 4 and form an additional safety attachment point. Thus, the two upper parts of the back straps 3 and 4 are formed with one of the back straps 3, and the two lower parts of the back straps 3 and 4 are formed with the other back strap 4.

[0067] The back strap 4 has an upward part passing over the back strap 3 and then folded back on itself and has a downward part passing behind the back strap 3. The two upward parts of the back strap 3 have an inclination between them substantially identical to the inclination of the two downward parts of the back strap 4.

[0068] The dorsal straps 3 and 4 are joined together, by means of seams, at the level of their overlap area.

[0069] Advantageously, the safety harness 1 includes a dorsal fall arrest loop, not shown in the figures, added by overstitching on the overlap area of ​​the dorsal straps 3, 4.

[0070] According to one embodiment, the safety harness 1 includes a support strap 28 mounted at the bottom of the back panel 2. The support strap 28, engaged in elastic loops of the back panel 2, connects the back straps 3 and 4. The support strap 28 advantageously includes an adjustment buckle to modify the spacing between the back straps 3 and 4. The safety harness 1 can therefore be adapted to best suit, in particular, the body size of the wearer of said safety harness 1.

[0071] According to one embodiment, the support strap 28 has two fastening clips 29 for non-elastic, length-adjustable leg straps 30. The leg straps 30 are connected to the thigh straps 7 and 8, which allows the safety harness 1 to be adapted to the wearer's morphology and pelvic orientation, and in particular to correct a retroversion / anteversion of the pelvis.

[0072] Fig. 8 is an enlarged view of a detail of the safety harness of Fig. 7. According to one embodiment, each shoulder strap 5, 6 has three suspension loops 16 distributed along said strap 5, 6 to form on each strap 5, 6 a front attachment point 16a, a central attachment point 16b, and a rear attachment point 16c. These front 16, central 16b, and rear 16c attachment points are distributed on the respective shoulder straps 5 and 6 along a left or right sagittal plane. This distribution allows a person suspended by the safety harness 1 to achieve different inclinations, including, for example, a forward inclination, a near-perfect vertical position, and a backward inclination.

[0073] According to one embodiment, the suspension loops 16 are made with strap loops sewn onto the straps 5, 6 using seams 21.

[0074] According to one embodiment, the safety harness 1 includes a visual indicator for proper donning, allowing verification that the donning of the harness complies with all safety requirements and, in particular, that the attachment point 16a, 16b, or 16c is used. The visual indicator includes, for example, a color code or different markings, such as numbers or letters, associated with the respective attachment points 16a, 16b, and 16c. The visual indicator may advantageously be supplemented with tactile markings for visually impaired persons.

[0075] Fig. 9 is an illustration of an example of the realization of a spreader bar 22 adapted to the safety harness 1 of figures 7 and 8.

[0076] The safety harness 1 comprises a rigid spreader bar 22, substantially in the shape of an inverted U, associated with at least one suspension strap 23. The spreader bar 22 is designed to extend around and away from the head of the wearer of said safety harness 1, approximately in a frontal plane of said wearer. The spreader bar 22 constrains the positioning of the suspension strap 23, i.e., said suspension strap 23 extends along said rigid spreader bar 22. The latter is preferably metallic, for example, made of steel.

[0077] Each end of the suspension strap 23 has a sewn end loop 23a into which is engaged a carabiner 25 intended to connect to an attachment point 16a, 16b or 16c of the suspension loop 16 of a shoulder strap 5, 6.

[0078] The central part of the suspension strap 23 is shaped, for example by sewing, into a strap loop 26 located substantially at the top of the inverted U-shape of the spreader bar 22.

[0079] According to another embodiment, the central part of the suspension strap 23 is provided with a central attachment ring at the top of the spreader bar 22.

[0080] The spreader bar 22 is advantageously fitted into a sleeve 27 made of technical fabric. The suspension strap 23 is advantageously sewn onto the sleeve 27.

[0081] According to another embodiment, not shown in the figures, the rigid spreader bar 22, substantially in the shape of an inverted U, is associated with at least two separate suspension straps 23. One end of each suspension strap is connected to an attachment point 16a, 16b, 16c of the suspension loop 16 of a shoulder strap 5, 6. The other end of each of the suspension straps 23 is then provided with a central attachment ring. The two central attachment rings are positioned at the top of the spreader bar 22 and constitute a separate attachment point specific to each suspension strap 23.

[0082] Fig. 10 is a front view of the safety harness 1 of Fig. 7, illustrating an example of mounting the spreader bar 22 on the suspension bridges 16. The spreader bar 22 allows complete freedom of movement of the head and arms of the person suspended by the safety harness 1.

[0083] Figure 11 is an enlarged view of another detail of the safety harness 1, illustrating a front view with the sternal loop 12. The side release buckle 14 comprises a male loop portion 14a and a female loop portion 14b connected after the sternal loop 12 passes through the ring 13, which is preferably circular in shape. This circular shape of the ring 13, combined with stitching and a slanted extension of each end 12a and 12b of the sternal loop 12 from the respective chest straps 11 and 10, increases the comfort of the wearer of the safety harness 1 and allows it to adapt better to their body shape.

[0084] The junction areas between the pectoral straps 11, 10 and the sternal bridge 12, are for example provided with a foam element 17a to create a soft, optimized-shaped layer that comes into direct contact with the wearer of the safety harness 1.

[0085] Figures 12, 13 and 14 illustrate a safety harness 1 according to the invention, worn by a person (carrier) suspended by a rope, wire rope or webbing la, at different attachment points 16a, 16b and 16c on the shoulder straps 5, 6. An additional safety rope 1b is advantageously connected to a different attachment point than that used for the rope, wire rope or webbing la.

[0086] Figure 12 shows the use of the front attachment point 16a of the suspension bridge 16 to attach the spreader bar 22, which is itself suspended from the strap 1a. The person suspended by the safety harness 1 is therefore, at rest, inclined backwards. This inclination, indicated by the dashed line VI, is, for example, +10° clockwise. Such an inclination is ideal for a person with at least partial use of their legs or a person who has had an arm amputated.

[0087] Figure 13 shows the use of the central attachment point 16b of the suspension bridge 16 to attach the spreader bar 22. The person suspended by the safety harness 1 is therefore, at rest, in a nearly vertical position. This inclination, materialized by the dashed line V2. Such verticality is ideal, for example, for a person with a partial deficiency of the arms and / or legs.

[0088] Figure 14 shows the use of the rear attachment point 16c of the suspension bridge 16 to attach the spreader bar 22. The person suspended by the safety harness 1 is therefore at rest in a forward tilt. This tilt, indicated by the dashed line V3, is, for example, -5° counterclockwise. Such a tilt is ideal for a paraplegic or quadriplegic person.

[0089] Figure 15 illustrates a safety harness 1, suspended by the pectoral attachment point. The unused spreader bar 22 is tilted backward and rests on the back of the wearer of the safety harness 1. The spreader bar 22 can also be removed from the safety harness 1 using the attachment carabiners 25. The person suspended by the safety harness 1 is therefore, at rest, in a seated position with approximately 50% of the load distributed between the back and thighs of the wearer of the safety harness 1. Such a seated position is, for example, represented by the broken line V4. This position is ideal for an overweight person or a person with obesity (PSO), or for a worker at height who requires such a position to perform their work.

[0090] The safety harness 1 is for example associated with a motorized support and traction system connected to the suspension rings 16 via a rope, wire rope or strap so as to secure the person equipped with said safety harness 1. Such a motorized system can for example provide a traction force so as to reduce the effort to be made by the user when climbing a climbing wall.

[0091] According to one embodiment, the support and traction system is automated and includes a calculator to determine traction assistance to be provided based on the traction effort provided by the user during their movements or also to propose a permanent balancing of all or part of the load suspended from it.

[0092] It is evident that the present description is not limited to the explicitly described examples, but also includes other embodiments. Thus, a described technical feature may be replaced by an equivalent technical feature without departing from the scope of the present invention as defined by the claims.
