- the present invention relates to a suspension device, in particular a device that allows a person to be suspended from a main rope, in particular to move along this rope, for example by sliding, for example to prune a tree.
- a suspension device in particular a device that allows a person to be suspended from a main rope, in particular to move along this rope, for example by sliding, for example to prune a tree.
- other applications are also possible, such as climbing, especially sports.
- Devices of this type are already known in the prior art. They comprise a belt with backsplash intended to surround the pelvis of the user and two waders intended to surround each one part of the thighs of the user, the two waders being connected to the backseat belt by a system of belts, comprising a belt left side and a right side belt, each of which connects one of the right and left waders respectively to the backrest belt, and a central strap forming a bridge between the two right and left side belts.
- this loop system has the disadvantage that at each new displacement of the user, it must perform a new adjustment of the loops to balance its connection system between the backrest and waders and adapt to the new position. As soon as he wishes to move to another position, he must start the whole adjustment process again. Thus, the use of this climbing device is not very simple.
- the bridge strap In use, the bridge strap "rises" above belt 564, pulling up loops 550 and 550a and straps 534 and 546 which come hang around the belt 564 so that the user is tight in the device automatically. However, once tightened in the device under the effect of its weight, suspended from the carabiner 552, the user can no longer adjust the device in the transverse direction, the straps 546a and 546 having wrapped around the belt 564 and forming a knot that can no longer slide. Once the fireman tight in the device, when making a tilting movement to the left or right, the straps do not move and significant friction occurs on the bridge strap 578 which wears prematurely.
- the present invention aims to overcome the drawbacks of the prior art by proposing a climbing device of the aforementioned kind in which the wear of the central bridge belt is reduced, so that it is no longer necessary to change them as often.

- the living user if the living user is replaced by a lifeless manikin of identical shape, it will be maintained in balanced position by the system of the invention in a wide range of possible positions, between leaning to the right , leaning to the left, leaning forward, leaning backwards or a combination of two of these movements, and this automatically.
- the central position is balanced and if you lean a dummy or any object in any direction, it continues to rock under the effect of its weight.
- it comes to a human being in the case of these devices of the prior art, when he leans, he can by exerting a force to fight against this swing.
- the lifeless manikin or the object can not.
- the automatic adjustment means are such that it maintains a lifeless manikin in the shape of a human being or any other object in equilibrium even in slanted positions other than an equilibrium position of departure, and this automatically, ie without manual intervention on the device. This results for the user a great comfort, especially when pruning trees. He can concentrate all his efforts on pruning without having to worry about keeping himself in balance.
- the suspension is carried out at least one point of suspension of the central belt.
- the automatic adjustment means are arranged so as to automatically adjust the resultant of the forces applied by the loads on the at least one point of suspension of the central belt so that this resultant has a lateral component, that is to say in the plane of the belt, substantially zero.

- At least two rings fixed to the central belt forming a bridge, in particular at its two ends, and which slide along the auxiliary belts.
- the automatic adjustment means are constituted by the fact that at least two rings are provided fixed to the central belt forming a bridge, in particular at its two ends, and which slide along the auxiliary belts and at least one of the auxiliary belts, preferably each of the at least two auxiliary belts consist of two strips extending substantially the same length and substantially parallel to each other, the two strips passing inside the sliding ring along the respective auxiliary belt, the one of the straps being twisted with respect to the other, so that said one of the straps penetrates the ring by one side of the ring and the other strap enters through the other side and said one one of the strips comes out of the side by which said other strap is entered and the other strap out of the ring by the side by which said one of the strap is entered.
- the strips are in the form of flat strips which form a so-called Moebus surface.
- a climbing device consists of a backsplash intended to be applied around the user's pelvis and to be fixed by a belt 2 adjustable by a loop system 3.
- Two waders 4 to surround the thighs of the user and having an adjustable dimension also via a conventional loop system, are connected to the backsplash 1; or more exactly to the belt 2, by a metal buckle 6.
- the connecting system between the waders and the backrest comprises a first auxiliary belt 7, a second auxiliary belt 8 and a central belt 9.
- each auxiliary belt 7 and 8 is attached in a conventional manner to the loops 6 (folding of the tape on itself with locking of the buckle and securing seam), while the other end of each of the belts 7 and 8 is fixed by a loop identical to the loop 6 and in the same conventional manner also to the loop 16 of his respective thigh.
- the central belt 9 is constituted by a double band or strap which at each of its ends 10 and 11 is terminated by a ring 12 and 13 into which the belt 13 penetrates for the ring 13 and for the ring 12, the belt 8.
- the belt 7 consists of two flat strips 17 and 27, while the belt 8 consists of two flat strips 18 and 28.
- the two strips 17 and 27 meet at each of their two ends to be fixed to the fastening loop. 6 and the opposite attachment loop 16.
- the belt 7 extends from the loop 6 passing through the ring 13 to the loop 16.
- the band 17 enters through the outer side (the side facing outward of the figure 1 ) and out through the opposite side (inwardly of the figure), while the band 27 enters the ring from the inner side and exits from the outside. It is thus formed inside the ring a sort of cross between the two bands.
- the strips 17 and 27 consist of the same single band folded on itself.
- Each ring 12 and 13 can slide along the belt 7 or 8 by having a part thereof which is on the upper side of the intersection inside between the two strips 17, 27 and having another part which is located below the intersection 30 and between the two strips 17, 27, the two strips having thus been inverted at the crossing, so that the one which was on the outside of the figure is now inside and vice versa.
- the two waders each surround a thigh of the user, while the backrest is pressed against the back of the person by the belt 2.
- the thong 9 forming a bridge between the two belts 7 and 8 is, on the other hand, suspended in a suspension point 40 to a ring 41 which, itself, can slide along a main rope 50, the user being able to lock in any position along the rope 50 the sliding of the ring 41 by a locking system which is not shown in the figures but which is conventional.
- the user is kept in balanced suspension by the climbing device according to the invention.
- the load applied to the central belt at the point of suspension by the ring is still substantially perpendicular to the central belt and there is substantially no friction-related wear which would occur due to a longitudinal force (along of the belt) related to an imbalance in the system, a force that would have been created if the user had leaned without the rings changing their position along the auxiliary belts. As a result, the wear on the central belt is greatly reduced.
- the user is always balanced, the force exerted at the point of suspension by the loads being also substantially perpendicular to the central belt and without longitudinal component, so that there is no wear.
- the user can remain in this position by much less effort than if the two rings were remained in identical position relative to the side belts. Indeed, there is no longitudinal component against which he must fight to stay in the desired position.
- a system has thus been described which automatically balances the loads applied to the three load bearing points, so that the suspension force exerted by the ring on the central belt always remains substantially “vertical” whatever the position that he takes the suspended state.
- the rings slide slowly along the side belts and reach a new balanced position corresponding to the new equilibrium position by distributing the different forces exerted on the system in a balanced manner. This gives an automatic regulation of the balance according to the efforts of the user.
- the system performs what is called a force triangulation, ie it automatically ensures that the three forces from the three
- the supports have a resultant, in an XYZ coordinate system, in which XY would correspond to the plane passing through the three supports and Z the perpendicular to this plane, which extends along the Z axis only.
- the automatic adjustment means are such as to maintain a lifeless manikin in the shape of a human being in equilibrium even in bent positions other than a starting equilibrium position, and this automatically, ie without manual intervention on the device.
Abstract
Description
La présente invention se rapporte à un dispositif de suspension, notamment un dispositif qui permet à une personne d'être suspendue à une corde principale, notamment pour se déplacer le long de cette corde, par exemple par coulissement, par exemple pour élaguer un arbre. Cependant, d'autres applications sont également possibles, comme l'escalade, notamment sportive.The present invention relates to a suspension device, in particular a device that allows a person to be suspended from a main rope, in particular to move along this rope, for example by sliding, for example to prune a tree. However, other applications are also possible, such as climbing, especially sports.
On connaît déjà des dispositifs de ce genre dans l'art antérieur. Ils comportent une ceinture à dosseret destinée à ceinturer le bassin de l'utilisateur et deux cuissardes destinées à entourer chacune une partie des cuisses de l'utilisateur, les deux cuissardes étant reliées à la ceinture à dosseret par un système de courroies, comportant une courroie latérale gauche et une courroie latérale droite, qui chacune relie l'une des cuissardes droite et gauche respective à la ceinture à dosseret, et une courroie centrale formant pont entre les deux courroies latérales droite et gauche.Devices of this type are already known in the prior art. They comprise a belt with backsplash intended to surround the pelvis of the user and two waders intended to surround each one part of the thighs of the user, the two waders being connected to the backseat belt by a system of belts, comprising a belt left side and a right side belt, each of which connects one of the right and left waders respectively to the backrest belt, and a central strap forming a bridge between the two right and left side belts.
Ces dispositifs de l'art antérieur présentent, notamment, les inconvénients suivants. Lorsque l'utilisateur est stabilisé à un niveau donné le long de la corde principale, il souhaite en général effectuer des mouvements vers la gauche, vers la droite, vers l'arrière ou vers l'avant pour toute sorte de raison, par exemple pour réaliser un élagage. Lors de ces mouvements, le dispositif qui le suspend à la corde n'est plus équilibré de manière exacte et subit des contraintes non uniformes. Si, par exemple, l'utilisateur se penche vers la droite, il apparaît des forces ou contraintes plus importantes sur la partie gauche du système de courroies et, au cours du temps ces déplacement déséquilibrés dans toutes les directions entraînent une usure prématurée de la courroie centrale qui est en liaison avec la corde principale et cette courroie centrale doit être remplacée fréquemment. Or ce remplacement n'est pas simple à effectuer. En outre, lorsque l'utilisateur tente d'atteindre des endroits positionnés à sa droite, à sa gauche ou vers l'arrière ou l'avant et sort de la position de base dans laquelle il se tient droit, il doit de lui-même effectuer une compensation pour s'opposer au déséquilibre du système et cette compensation l'oblige à exercer constamment avec son corps des forces s'opposant aux forces issues du déséquilibre, ce qui fait qu'il n'est pas dans une position la plus agréable possible, alors même qu'il doit dans cette position effectuer un travail difficile, par exemple élaguer un arbre.These devices of the prior art have, in particular, the following disadvantages. When the user is stabilized at a given level along the main chord, he usually wants to move left, right, backward or forward for any reason, for example to prune. During these movements, the device that suspends the rope is no longer exactly balanced and undergoes non-uniform stresses. If, for example, the user leans to the right, there are greater forces or stresses on the left side of the belt system and, over time, these unbalanced movements in all directions lead to premature wear of the belt. central which is in connection with the main rope and this central belt must be replaced frequently. But this replacement is not easy to perform. In In addition, when the user attempts to reach positions positioned to his right, to his left, or to the rear or the front and out of the basic position in which he is standing straight, he must himself perform a compensation to oppose the imbalance of the system and this compensation forces him to constantly exercise with his body forces opposing forces resulting from the imbalance, which makes it not in a position as pleasant as possible , even though in this position he must do a difficult job, for example pruning a tree.
Suivant un perfectionnement déjà connu, on peut prévoir de régler manuellement la position relative de la courroie centrale par rapport à chacune des courroies latérales par l'intermédiaire de boucles. Cependant, ce système à boucles présente l'inconvénient qu'à chaque nouveau déplacement de l'utilisateur, il doit effectuer un nouveau réglage des boucles pour équilibrer son système de liaison entre le dosseret et les cuissardes et l'adapter à la nouvelle position. Dès qu'il souhaite passer dans une autre position, il doit recommencer tout le processus de réglage. Ainsi, l'utilisation de ce dispositif d'escalade n'est-elle pas très simple.According to an improvement already known, it can be provided to manually adjust the relative position of the central belt relative to each of the side belts by means of loops. However, this loop system has the disadvantage that at each new displacement of the user, it must perform a new adjustment of the loops to balance its connection system between the backrest and waders and adapt to the new position. As soon as he wishes to move to another position, he must start the whole adjustment process again. Thus, the use of this climbing device is not very simple.

La présente invention vise à surmonter les inconvénients de l'art antérieur en proposant un dispositif d'escalade du genre mentionné précédemment dans lequel l'usure de la courroie centrale formant pont est diminuée, de sorte qu'il n'est plus nécessaire d'en changer aussi souvent.The present invention aims to overcome the drawbacks of the prior art by proposing a climbing device of the aforementioned kind in which the wear of the central bridge belt is reduced, so that it is no longer necessary to change them as often.
Suivant l'invention, un dispositif de suspension destiné à être appliqué à un objet ou un utilisateur pour lui permettre d'être suspendu à une corde principale, notamment le long de laquelle il va pouvoir se déplacer, notamment par coulissement, et comportant au moins un support de charge principal, par exemple une ceinture à dosseret destiné à entourer le bassin de l'utilisateur, et au moins deux supports de charge auxiliaires, par exemple deux cuissardes destinées à chacune entourer une cuisse de l'utilisateur, et un système de liaison pour relier le au moins un support de charge principale au aux moins deux supports de charge auxiliaires, le système de liaison étant constitué au moins d'une première courroie reliant le au moins un support de charge principal à l'un des deux supports auxiliaires, d'une deuxième courroie reliant le au moins un support principal au deuxième support auxiliaire et d'une courroie centrale reliée à chacune des au moins deux courroies auxiliaires, est caractérisé en ce qu'il est prévu des moyens de réglage automatique de l'équilibrage de l'objet ou de l'utilisateur à l'état suspendu à la corde principale, de sorte que celui ci, lorsqu'il passe d'une position à une autre dans un domaine de positions correspondant à un basculement vers l'avant, l'arrière, la gauche, la droite ou une combinaison de deux basculements de ce genre, reste en une position équilibrée, dans laquelle il peut rester, notamment en étant inerte comme un mannequin.According to the invention, a suspension device intended to be applied to an object or a user to enable it to be suspended from a main rope, in particular along which it will be able to move, in particular by sliding, and comprising at least a main load support, for example a backrest belt intended to surround the user's pelvis, and at least two auxiliary load supports, for example two waders intended to surround each one a thigh of the user, and a support system; linkage for connecting the at least one main load carrier to the at least two auxiliary load carriers, the connection system comprising at least a first belt connecting the at least one main load carrier to one of the two auxiliary supports , a second belt connecting the at least one main support to the second auxiliary support and a central belt connected to each of the at least two belts auxiliaries, is characterized in that there is provided means for automatically adjusting the balancing of the object or the user in the state suspended on the main rope, so that it, when it passes from one position to another in a range of positions corresponding to a tilt forward, the rear, the left , the right or a combination of two tilts of this kind, remains in a balanced position, in which it can remain, including being inert like a mannequin.
Ainsi suivant l'invention, si on remplace l'utilisateur vivant par un mannequin sans vie de forme identique, celui ci va être maintenu en position équilibrée par le système de l'invention dans une grande plage de positions possibles, entre penché vers la droite, penché vers la gauche, penché vers l'avant, penché vers l'arrière ou une combinaison de deux de ces mouvements, et ce de manière automatique. Dans les dispositifs de suspension antérieurs, seule la position centrale est équilibré et si on penche un mannequin ou un objet quelconque dans une direction quelconque, celui ci continue de basculer sous l'effet de son poids. Lorsqu'il s'agit d'un être humain, dans le cas de ces dispositifs de l'art antérieur, lorsqu'il se penche, il peut en exerçant une force lutter contre ce basculement. Le mannequin sans vie ou l'objet ne le peut pas. Ainsi, suivant l'invention, les moyens de réglage automatique sont tels qu'il maintienne un mannequin sans vie de la forme d'un être humain ou un objet quelconque en équilibre même dans des positions penchées autre qu'une position d'équilibre de départ, et ce de manière automatique, c'est à dire sans intervention manuelle sur le dispositif. Il en résulte pour l'utilisateur un grand confort, en particulier lorsqu'il élague des arbres. Il peut concentrer tous ses efforts sur l'élagage sans avoir à se soucier de se maintenir en équilibre.Thus according to the invention, if the living user is replaced by a lifeless manikin of identical shape, it will be maintained in balanced position by the system of the invention in a wide range of possible positions, between leaning to the right , leaning to the left, leaning forward, leaning backwards or a combination of two of these movements, and this automatically. In the previous suspension devices, only the central position is balanced and if you lean a dummy or any object in any direction, it continues to rock under the effect of its weight. When it comes to a human being, in the case of these devices of the prior art, when he leans, he can by exerting a force to fight against this swing. The lifeless manikin or the object can not. Thus, according to the invention, the automatic adjustment means are such that it maintains a lifeless manikin in the shape of a human being or any other object in equilibrium even in slanted positions other than an equilibrium position of departure, and this automatically, ie without manual intervention on the device. This results for the user a great comfort, especially when pruning trees. He can concentrate all his efforts on pruning without having to worry about keeping himself in balance.
Suivant un perfectionnement de l'invention, la suspension s'effectue en au moins un point de suspension de la courroie centrale.According to an improvement of the invention, the suspension is carried out at least one point of suspension of the central belt.
On obtient ainsi une moindre usure de cette courroie centrale et une plus longue durée de vie de celle ci.This gives a lower wear of this central belt and a longer life of it.
Suivant un perfectionnement de l'invention, les moyens de réglage automatique sont agencés de manière à régler automatiquement la résultante des forces appliquées par les charges sur le au moins un point de suspension de la courroie centrale de sorte que cette résultante ait une composante latérale, c'est à dire dans le plan de la courroie, sensiblement nulle.According to an improvement of the invention, the automatic adjustment means are arranged so as to automatically adjust the resultant of the forces applied by the loads on the at least one point of suspension of the central belt so that this resultant has a lateral component, that is to say in the plane of the belt, substantially zero.
On obtient ainsi, en utilisation, un équilibrage parfait pour l'utilisateur ou l'objet dans sensiblement toutes les positions qu'il souhaite prendre. Il en résulte une usure moindre sur la courroie centrale qui, par conséquent, a moins besoin d'être changée que dans l'art antérieur. En outre, l'utilisateur se fatigue moins lors d'un travail, notamment dans le cas où il élague des arbres. En effet, avec ce système, il peut se maintenir en équilibre sans être nécessairement droit ni avoir à modifier de lui-même par des systèmes compliqués à boucle les positions relatives des courroies du système de liaison.Thus, in use, a perfect balancing is obtained for the user or the object in substantially all the positions he wishes to take. This results in less wear on the central belt which, therefore, has less need to be changed than in the prior art. In addition, the user is less tired during work, especially in the case where he prune trees. Indeed, with this system, it can be maintained in balance without being necessarily right or have to change of itself by complicated systems to loop the relative positions of the belts of the connection system.
Suivant un mode de réalisation préféré de l'invention, les moyens de réglage automatique sont agencés de manière à régler la position relative de la courroie centrale par rapport au aux moins deux courroies auxiliaires, en fonction des mouvements de l'utilisateur.According to a preferred embodiment of the invention, the automatic adjustment means are arranged to adjust the relative position of the central belt relative to the at least two auxiliary belts, depending on the movements of the user.
Suivant un perfectionnement de l'invention, il est prévu au moins deux anneaux fixées à la courroie centrale formant pont, notamment à ses deux extrémités, et qui coulissent le long des courroies auxiliaires.According to an improvement of the invention, there are provided at least two rings fixed to the central belt forming a bridge, in particular at its two ends, and which slide along the auxiliary belts.
Suivant un mode de réalisation préféré de l'invention, les moyens de réglage automatique sont constitués par le fait qu'il est prévu au moins deux anneaux fixées à la courroie centrale formant pont, notamment à ses deux extrémités, et qui coulissent le long des courroies auxiliaires et qu'au moins une des courroies auxiliaires, de préférence chacune des au moins deux courroies auxiliaires est constituée de deux lanières s'étendant sensiblement sur la même longueur et sensiblement parallèlement l'une à l'autre, les deux lanières passant à l'intérieur de l'anneau coulissant le long de la courroie auxiliaire respective, l'une des lanières étant torsadée par rapport à l'autre, de sorte que ladite une des lanières pénètre dans l'anneau par l'un des côtés de l'anneau et l'autre lanière y pénètre par l'autre côté et ladite l'une des lanières sort du côté par lequel ladite autre lanière est entrée et l'autre lanière sort de l'anneau par le côté par lequel ladite l'une des lanière y est entrée.According to a preferred embodiment of the invention, the automatic adjustment means are constituted by the fact that at least two rings are provided fixed to the central belt forming a bridge, in particular at its two ends, and which slide along the auxiliary belts and at least one of the auxiliary belts, preferably each of the at least two auxiliary belts consist of two strips extending substantially the same length and substantially parallel to each other, the two strips passing inside the sliding ring along the respective auxiliary belt, the one of the straps being twisted with respect to the other, so that said one of the straps penetrates the ring by one side of the ring and the other strap enters through the other side and said one one of the strips comes out of the side by which said other strap is entered and the other strap out of the ring by the side by which said one of the strap is entered.
Il est ainsi formé une sorte de noeud ou croisement au niveau de l'anneau, qui est ainsi supporté entre les deux lanières et qui peut coulisser le long des deux lanières entre celles-ci. En outre, la torsion créée au niveau d'une lanière fait que le coulissement a lieu avec un certain frottement permettant d'assurer un coulissement progressif, de manière fluide et sans à-coups, jusqu'à la position d'équilibre sans dépasser celle-ci.There is thus formed a kind of knot or crossing at the level of the ring, which is thus supported between the two strips and which can slide along the two strips between them. In addition, the twist created at a strap makes the sliding occurs with a certain friction to ensure a smooth sliding smoothly and smoothly to the equilibrium position without exceeding that -this.
Suivant un perfectionnement de l'invention, les lanières sont en forme de bandes plates qui forment une surface dite de Moëbus.According to an improvement of the invention, the strips are in the form of flat strips which form a so-called Moebus surface.

L'utilisateur est toujours équilibré, la force exercée au point de suspension par les charges étant également sensiblement perpendiculaire à la courroie centrale et sans composante longitudinale, de sorte qu'il n'y a pas d'usure. L'utilisateur peut rester dans cette position en faisant beaucoup moins d'efforts que si les deux anneaux étaient restés en position identique par rapport aux courroies latérales. En effet, il n'y a plus de composante longitudinale contre laquelle il doit lutter pour rester dans la position souhaitée.The user is always balanced, the force exerted at the point of suspension by the loads being also substantially perpendicular to the central belt and without longitudinal component, so that there is no wear. The user can remain in this position by much less effort than if the two rings were remained in identical position relative to the side belts. Indeed, there is no longitudinal component against which he must fight to stay in the desired position.
On a ainsi décrit un système qui automatiquement, équilibre les charges appliquées aux trois points de support de charge, de sorte que la force de suspension exercée par l'anneau sur la courroie centrale reste toujours sensiblement « verticale » quelle que soit la position qu'il prenne à l'état suspendu. Au fur et à mesure que l'utilisateur se déplace, les anneaux coulissent lentement le long des courroies latérales et atteignent une nouvelle position équilibrée correspondant à la nouvelle position d'équilibre en répartissant les différentes forces exercées sur le système de manière équilibrée. On obtient ainsi une régulation automatique de l'équilibre en fonction des efforts de l'utilisateur. Le système effectue ce que l'on appelle une triangulation des forces, c'est à dire qu'il fait en sorte automatiquement que les trois forces issues des trois supports ait une résultante, dans un système de coordonnées XYZ, dans lequel XY correspondraient au plan passant par les trois supports et Z la perpendiculaire à ce plan, qui s'étend suivant l'axe des Z uniquement.A system has thus been described which automatically balances the loads applied to the three load bearing points, so that the suspension force exerted by the ring on the central belt always remains substantially "vertical" whatever the position that he takes the suspended state. As the user moves, the rings slide slowly along the side belts and reach a new balanced position corresponding to the new equilibrium position by distributing the different forces exerted on the system in a balanced manner. This gives an automatic regulation of the balance according to the efforts of the user. The system performs what is called a force triangulation, ie it automatically ensures that the three forces from the three The supports have a resultant, in an XYZ coordinate system, in which XY would correspond to the plane passing through the three supports and Z the perpendicular to this plane, which extends along the Z axis only.
Suivant l'invention, si on remplace un utilisateur vivant par un mannequin sans vie, celui ci va être maintenu en position équilibrée par le système de l'invention dans une grande plage de positions possibles, entre penché vers la droite, penché vers la gauche, penché vers l'avant, penché vers l'arrière ou une combinaison de deux de ces mouvements, et ce de manière automatique. Dans les dispositifs d'escalade antérieur, seule la position centrale est équilibré et si on penche un mannequin dans une direction quelconque, celui ci va tomber. Lorsqu'il s'agit d'un être humain, dans le cas de ces dispositifs de l'art antérieur, lorsqu'il se penche, il peut en exerçant une force s'opposer à cette chute. Le mannequin sans vie ne le peut pas. Ainsi, suivant l'invention, les moyens de réglage automatique sont tels qu'il maintienne un mannequin sans vie de la forme d'un être humain en équilibre même dans des positions penchées autre qu'une position d'équilibre de départ, et ce de manière automatique, c'est à dire sans intervention manuelle sur le dispositif.According to the invention, if a living user is replaced by a lifeless manikin, the latter will be maintained in a balanced position by the system of the invention in a wide range of possible positions, between leaning to the right, leaning to the left , leaning forward, leaning backward or a combination of two of these movements, and this automatically. In the previous climbing devices, only the central position is balanced and if we bend a manikin in any direction, it will fall. When it comes to a human being, in the case of these devices of the prior art, when he leans, he can exert a force to oppose this fall. The lifeless mannequin can not. Thus, according to the invention, the automatic adjustment means are such as to maintain a lifeless manikin in the shape of a human being in equilibrium even in bent positions other than a starting equilibrium position, and this automatically, ie without manual intervention on the device.
