Description

La présente invention se rapporte à un dispositif de sécurité pour le transport dans un véhicule d'une personne circulant en fauteuil roulant.The present invention relates to a safety device for the transport in a vehicle of a person traveling in a wheelchair.

Le transport par autocars ou autres véhicules terrestres, par navires ou par avions de personnes circulant en fauteuil roulant a toujours posé des problèmes. Ces véhicules sont en effet continuellement sujets à des forces diverses (accélération, décélération, force centrifuge, roulis, tangage, se- couses diverses, etc...) sans parler des chocs en cas d'accident. Le simple blocage des roues d'un fauteuil roulant par des freins ne procure pas à l'occupant du fauteuil une protection suffisante. De même, la présence éventuelle d'un garde personnel accompagnant l'occupant d'un fauteuil roulant est pratiquement sans effet à ce sujet.Transporting people in wheelchairs by coach or other land vehicle, ship or plane has always been a problem. These vehicles are in fact continually subject to various forces (acceleration, deceleration, centrifugal force, roll, pitch, various swaying, etc.) not to mention shock in the event of an accident. Simply locking the wheels of a wheelchair with brakes does not provide the occupant of the wheelchair with sufficient protection. Likewise, the possible presence of a personal guard accompanying the occupant of a wheelchair has practically no effect on this subject.

C'est la raison pour laquelle les personnes circulant en fauteuil roulant ne peuvent pas se déplacer aussi facilement qu'ils le désirent. Ce problème a été reconnu peu à peu, mais jusqu'à l'heure actuelle, aucune solution efficace permettant à ces personnes désavantagées de jouir d'une liberté de mouvement, donc d'une indépendance, plus grande, n'a été mise au point. Le transport de personnes circulant en fauteuil roulant implique jusqu'à présent des véhicules spécialement aménagés, et souvent aussi des modifications importantes aux fauteuils roulants eux-mêmes pour permettre l'immobilisation de ces derniers dans les véhicules. Néanmoins, cette immobilisation des fauteuils roulants ne procure pas de protection efficace aux occupants de ces fauteuils et ne peut pas être réalisée sans la présence d'un aide.This is the reason why people in wheelchairs cannot get around as easily as they want. This problem has been gradually recognized, but until now, no effective solution allowing these disadvantaged people to enjoy freedom of movement, and therefore, greater independence, has been put in place. point. The transport of people circulating in a wheelchair implies until now specially adapted vehicles, and often also important modifications to the wheelchairs themselves to allow the immobilization of these last in the vehicles. However, this immobilization of wheelchairs does not provide effective protection for the occupants of these wheelchairs and cannot be achieved without the presence of an assistant.

La présente invention a pour objet un dispositif de sécurité simple, n'impliquant que des adaptations de faible importance sur un véhicule de transport classique et sur des fauteuils roulants classiques tout en procurant aux occupants des fauteuils roulants, sans l'assistance d'un garde ou d'une autre personne, une protection efficace à la fois contre les effets des forces qui se produisent pendant le fonctionnement normal des véhicules et contre les effets des chocs survenant en cas d'accident éventuel.The present invention relates to a simple safety device, involving only minor adaptations on a conventional transport vehicle and on conventional wheelchairs while providing the occupants with wheelchairs, without the assistance of a guard. or another person, effective protection against both effects of the forces which occur during normal vehicle operation and against the effects of shocks occurring in the event of a possible accident.

Le dispositif de sécurité conforme à l'invention pour le transport, dans un véhicule, d'une personne circulant en fauteuil roulant comprend une ceinture de sécurité fixée au fauteuil roulant pour retenir la personne sur ce dernier et un mécanisme d'ancrage du fauteuil roulant au véhicule de transport.The safety device according to the invention for the transport, in a vehicle, of a person circulating in a wheelchair comprises a safety belt fixed to the wheelchair to retain the person on the latter and a mechanism for anchoring the wheelchair to the transport vehicle.

La combinaison de ces deux moyens assure à la fois l'immobilisation du fauteuil roulant par rapport au véhicule de transport et l'immobilisation, par rapport au fauteuil roulant, de la personne occupant ce dernier. Cette combinaison de deux fonctions de retenue fait que l'occupant du siège ne subit pas les effets de l'inertie de la masse du fauteuil roulant. L'occupant du fauteuil peut s'attacher lui-même sur le fauteuil à l'aide de la ceinture de sécurité et immobiliser le fauteuil roulant par rapport au véhicule par le mécanisme d'ancrage, et peut également se libérer, si nécessaire, par ses propres moyens à la suite d'un accident.The combination of these two means ensures both the immobilization of the wheelchair relative to the transport vehicle and the immobilization, relative to the wheelchair, of the person occupying the latter. This combination of two restraint functions means that the seat occupant is not affected by the inertia of the mass of the wheelchair. The occupant of the wheelchair can fasten himself on the wheelchair using the seat belt and immobilize the wheelchair relative to the vehicle by the anchoring mechanism, and can also be released, if necessary, by own means following an accident.

Le mécanisme d'ancrage comprend au moins un organe de retenue solidaire du véhicule et deux organes d'accrochage montés sur le fauteuil roulant et actionnés par l'occupant du fauteuil pour coopérer avec ledit organe de retenue.The anchoring mechanism comprises at least one retaining member secured to the vehicle and two hooking members mounted on the wheelchair and actuated by the occupant of the chair to cooperate with said retaining member.

Afin que les efforts auxquelles la ceinture de sécurité équipant le fauteuil roulant est soumise en cas d'accident éventuel du véhicule de transport soient reportés sur le véhicule directement et non pas par l'intermédiaire du fauteuil roulant, il est avantageux que la ceinture de sécurité soit fixée aux organes d'accrochage ou à l'élément de support desdits organes sur le châssis du fauteuil roulant. Cela évite également à l'occupant du fauteuil de supporter le poids de ce dernier en cas de choc.So that the forces to which the seat belt fitted to the wheelchair is subjected in the event of a possible accident of the transport vehicle are transferred to the vehicle directly and not via the wheelchair, it is advantageous for the seat belt either fixed to the attachment members or to the support element of said members on the chassis of the wheelchair. This also prevents the occupant of the chair from supporting the weight of the chair in the event of an impact.

Suivant un mode de réalisation, ledit organe de retenue peut être avantageusement constitué par un profilé allongé fixé au plancher du véhicule transversalement à la direction de marche normale du véhicule de manière que l'un des bords longitudinaux dudit profilé soit dégagé et soit accessible à. la fois depuis le bas et dans un sens suivant la direction 4e marche normale du véhicule. Ledit organe d'accrochage comprend alors avantageusement une patte de préhension montée sur le fauteuil roulant de manière à pouvoir être engagée en dessous dudit bord dégagé du profilé fixé au plancher et à pouvoir être relevé en vue de son accrochage sous ledit bord du profilé et verrouillée dans cette position par rapport au fauteuil roulant.According to one embodiment, said retaining member may advantageously be constituted by an elongated profile fixed to the floor of the vehicle transversely to the normal running direction of the vehicle so that one of the edges longitudinal of said profile is free and is accessible to. both from the bottom and in a direction in the direction of the normal fourth step of the vehicle. Said attachment member then advantageously comprises a gripping tab mounted on the wheelchair so as to be able to be engaged below said edge released from the profile fixed to the floor and to be able to be raised for hooking under said edge of the profile and locked in this position relative to the wheelchair.

Le profilé transversal non seulement assure une retenue parfaite, mais permet également l'accrochage de pattes de préhension ayant des écartements différents du fait du montage des deux organes d'accrochage sur des fauteuils roulants de largeurs différentes.The transverse profile not only ensures perfect retention, but also allows the attachment of gripping tabs having different spacings due to the mounting of the two attachment members on wheelchairs of different widths.

De préférence, ladite patte de préhension est disposée à l'extrémité inférieure d'une tige montée coulissante dans un tube fixé dans une position sensiblement verticale au fauteuil roulant, entre les roues avant et les roues arrière de ce dernier, ladite tige portant à son extrémité supérieure un moyen susceptible d'être actionné de façon simple par l'occupant du fauteuil roulant pour relever ladite tige par rapport audit tube et la bloquer en position relevée par rapport audit tube.Preferably, said gripping tab is disposed at the lower end of a rod mounted to slide in a tube fixed in a substantially vertical position to the wheelchair, between the front wheels and the rear wheels of the latter, said rod carrying its upper end means capable of being actuated in a simple manner by the occupant of the wheelchair to raise said rod relative to said tube and block it in the raised position relative to said tube.

Ledit moyen d'actionnement comprend de préférence un excentrique articulé par un axe sensiblement horizontal sur l'extrémité supérieure de ladite tige de manière que sa surface périphérique, formant came, coopère avec l'extrémité supérieure du tube, ainsi qu'une manette de manoeuvre fixée audit excentrique pour permettre la rotation de ce dernier, en vue du relèvement de la tige par rapport au tube et du blocage de la tige en position relevée, la patte de préhension étant accrochée sous le bord dégagé du profilé de retenue.Said actuation means preferably comprises an eccentric articulated by a substantially horizontal axis on the upper end of said rod so that its peripheral surface, forming a cam, cooperates with the upper end of the tube, as well as an operating lever. fixed to said eccentric to allow rotation of the latter, with a view to raising the rod relative to the tube and blocking the rod in the raised position, the gripping tab being hooked under the free edge of the retaining profile.

Le profilé de retenue peut être avantageusement encastré dans le plancher du véhicule de transport de manière que son bord dégagé se trouve sensiblement à la hauteur du plancher.The retaining profile can advantageously be embedded in the floor of the transport vehicle so that its clear edge is substantially at the height of the floor.

Pour assurer une bonne immobilisation du fauteuil roulant dans les deux sens de la direction de marche normale du véhicule, c'est-à-dire à la fois vers l'avant et vers l'arrière, il est avantageux que ledit bord dégagé du profilé de retenue présente un rebord tourné vers le bas et que ladite patte de préhension de chaque organe d'accrochage présente un rebord tourné vers le haut.'To ensure that the wheelchair is properly immobilized in both directions of normal vehicle driving direction cule, that is to say both forwards and backwards, it is advantageous that said free edge of the retaining profile has a flange facing downwards and that said gripping tab of each member d 'hanging has an edge facing upwards.'

De préférence, chaque organe d'accrochage comporte en outre un moyen pour immobiliser la tige coulissante par rapport au tube dans une position suffisamment relevée pour que la patte de préhension dégagée du profilé de retenue se trouve au-dessus du plancher du véhicule et ne gêne pas la circulation normale du fauteuil roulant.Preferably, each fastening member further comprises means for immobilizing the sliding rod relative to the tube in a position sufficiently raised so that the grip tab released from the retaining profile is located above the vehicle floor and does not interfere not normal wheelchair traffic.

De préférence, la ceinture de sécurité est du type à trois points et à enrouleur à inertie. L'une des colonnes du dossier du fauteuil peut être prolongée au-dessus de la hauteur des épaules de l'occupant et porter à son extrémité supérieure un renvoi pour la sangle de la ceinture dont une extrémité est fixée à l'un des organes d'accrochage et dont l'autre extrémité part de l'enrouleur fixé à l'arrière du fauteuil, la boucle de la ceinture étant fixée à l'autre organe d'accrochage.Preferably, the seat belt is of the three-point type and with inertia reel. One of the columns of the back of the chair can be extended above the height of the occupant's shoulders and carry at its upper end a reference for the belt strap, one end of which is fixed to one of the 'hooking and whose other end starts from the reel fixed to the rear of the chair, the belt buckle being fixed to the other hooking member.

Suivant un autre mode de réalisation de l'invention, le mécanisme d'ancrage du fauteuil roulant au véhicule de transport comprend deux organes de retenue reliés au véhicule à une distance réciproque réglable sur la largeur du fauteuil roulant et deux organes d'accrochage de longueur réglable montés sur le fauteuil roulant de manière à pouvoir être accrochés auxdits deux organes.de retenue sur les deux côtés opposés du , fauteuil.According to another embodiment of the invention, the mechanism for anchoring the wheelchair to the transport vehicle comprises two retaining members connected to the vehicle at a reciprocal distance adjustable over the width of the wheelchair and two latching members of length adjustable mounted on the wheelchair so as to be able to be hooked to said two retaining members on the two opposite sides of the wheelchair.

L'occupant du fauteuil roulant peut ainsi, en augmentant la longueur des deux organes d'accrochage, accrocher ces derniers aux deux organes de retenue reliés au véhicule même si le fauteuil roulant n'occupe pas une position optimale par rapport à ces deux organes de retenue. Il amène ensuite le fauteuil roulant à la position correcte et réduit alors à une valeur minimale la longueur des deux organes d'accrochage.The occupant of the wheelchair can thus, by increasing the length of the two fastening members, hook the latter to the two retaining members connected to the vehicle even if the wheelchair does not occupy an optimal position relative to these two retaining members. detention. He then brings the wheelchair to the correct position and then reduces the length of the two hooking devices to a minimum.

De préférence, lesdits organes de retenue comprennent chacun une boucle de verrouillage et lesdits organes d'accrochage comprennent chacun un lien souple de longueur réglable tel qu'une sangle, pourvu à une extrémité d'une languette susceptible d'être verrouillée dans ladite boucle, de façon analogue au bouclage d'une ceinture de sécurité.Preferably, said retaining members each comprise a locking loop and said hooking members each include a flexible link of adjustable length such as a strap, provided at one end with a tongue capable of being locked in said loop, in a manner similar to the fastening of a seat belt.

Pour simplifier le réglage de longueur des deux liens des organes d'accrochage, chacun de ces deux liens peut être relié au fauteuil par un enrouleur automatique, par exemple du type à inertie, analogue aux enrouleurs utilisés pour les ceintures de sécurité.To simplify the length adjustment of the two links of the fastening members, each of these two links can be connected to the chair by an automatic retractor, for example of the inertia type, similar to the retractors used for seat belts.

Suivant une variante de réalisation préférée, les deux liens des organes d'accrochage sont reliés au fauteuil par un enrouleur commun du type rétracteur dont le châssis est mobile en translation dans une glissière transversale à la direction longitudinale du fauteuil. Dans ce cas, l'un des deux liens est enroulé sur l'axe de l'enrouleur et l'autre lien, de longueur fixe, est attaché au châssis de cet enrouleur. Cette variante de réalisation plus simple et moins coûteuse que celle à deux enrouleurs permet néanmoins à l'occupant du fauteuil roulant d'ancrer ce dernier au véhicule par une manoeuvre extrêmement simple.According to a preferred embodiment, the two links of the fastening members are connected to the chair by a common retractor type retractor whose chassis is movable in translation in a slide transverse to the longitudinal direction of the chair. In this case, one of the two links is wound on the axis of the reel and the other link, of fixed length, is attached to the chassis of this reel. This simpler and less expensive variant of embodiment than that with two reels nevertheless allows the occupant of the wheelchair to anchor the latter to the vehicle by an extremely simple operation.

Les boucles de verrouillage peuvent être reliées aux parois ou au plancher du véhicule de transport. Dans ce dernier cas, elles sont avantageusement disposées aux extrémités supérieures de montants flexibles et élastiques fixés au plancher du véhicule. Chaque boucle peut être supportée par un unique montant flexible ou alors par deux montants flexibles fixés au plancher du véhicule en deux points espacés suivant une droite parallèle à l'axe, longitudinal du fauteuil à ancrer, lesdits deux montants se rejoignant à la hauteur de la boucle. Ces montants flexibles présentent une hauteur telle que les boucles soient à la portée de l'occupant du fauteuil roulant.The locking loops can be connected to the walls or the floor of the transport vehicle. In the latter case, they are advantageously arranged at the upper ends of flexible and elastic uprights fixed to the floor of the vehicle. Each loop can be supported by a single flexible upright or else by two flexible uprights fixed to the vehicle floor at two points spaced along a straight line parallel to the axis, longitudinal of the chair to be anchored, said two uprights meeting at the height of the loop. These flexible uprights have a height such that the loops are within the reach of the occupant of the wheelchair.

Referring to the accompanying drawings, there will be described below in more detail two illustrative and non-limiting embodiments of a safety device according to the invention; on the drawings:
  • fig. 1 is a side elevational view of a safety device according to the invention for the transport by vehicle of a person traveling in a wheelchair;
  • fig. 2 is a front elevational view of the same device;

  • fig. 5 shows another embodiment of a security device according to the invention.

Les fig. 1 et 2 illustrent un fauteuil roulant classique comprenant un châssis tubulaire formé de deux moitiés latérales 1. Chaque moitié de châssis 1 comprend un montant avant 2 et un montant arrière 3 reliés entre eux par un longeron inférieur 4 et un longeron supérieur 5. Chaque moitié de châssis 1 comporte à l'arrière une grande roue fixe 6 et à l'avant une petite roue orientable 7.Figs. 1 and 2 illustrate a conventional wheelchair comprising a tubular chassis formed by two lateral halves 1. Each chassis half 1 comprises a front upright 2 and a rear upright 3 connected together by a lower spar 4 and an upper spar 5. Each half chassis 1 has at the rear a large fixed wheel 6 and at the front a small steerable wheel 7.

Les deux moitiés de châssis 1 sont reliées entre elles par une assise 8 et, en dessous de cette dernière, par un système de bielles 9 permettant le pliage du châssis.The two chassis halves 1 are interconnected by a seat 8 and, below the latter, by a system of connecting rods 9 allowing the chassis to be folded.

Le dossier 10 est supporté à l'arrière du fauteuil par deux colonnes 11 dont chacune est fixée à l'une des moitiés de châssis 1.The backrest 10 is supported at the rear of the chair by two columns 11, each of which is fixed to one of the chassis halves 1.

Pour permettre le transport, en toute sécurité, de l'occupant du fauteuil roulant dans un véhicule (véhicule terrestre, bateau, avion, etc..) le fauteuil roulant est équipé d'une ceinture de sécurité pour retenir l'occupant du fauteuil sur ce dernier et d'un mécanisme d'ancrage du fauteuil roulant au véhicule.To allow the safe transport of the occupant of the wheelchair in a vehicle (land vehicle, boat, plane, etc.) the wheelchair is fitted with a seat belt to hold the occupant of the wheelchair on the latter and a mechanism for anchoring the wheelchair to the vehicle.

Le mécanisme d'ancrage du fauteuil au véhicule comprend un organe 12 fixé à chaque moitié de châssis 1 pour l'accrochage du fauteuil roulant au plancher 13 du véhicule de transport. Pour permettre l'accrochage de l'organe 12 au plancher 13 du véhicule, un profilé de retenue 14 est encastré dans le plancher 13. Le profilé de retenue 14 présente la forme d'une auge ouverte vers le haut, disposée transversalement à la direction de marche du véhicule. Le flanc arrière du profilé 14 s'étend de façon oblique vers l'arrière et vers le haut, jusqu'à la face supérieure du plancher 13. Le flanc avant du profilé 14 est prolongé vers l'arrière, au niveau de la face supérieure du plancher 13, par un bord horizontal 15 qui se termine par un rebord 16 orienté vers le bas. Le bord 15 est ainsi dégagé et accessible à la fois depuis le bas et de l'arrière dans le sens de marche du véhicule.The mechanism for anchoring the wheelchair to the vehicle comprises a member 12 fixed to each half of the chassis 1 for attaching the wheelchair to the floor 13 of the transport vehicle. To allow the attachment of the member 12 to the floor 13 of the vehicle, a retaining profile 14 is embedded in the floor 13. The retaining profile 14 has the shape of a trough open upwards, arranged transversely to the direction vehicle. The rear flank of the profile 14 extends obliquely backwards and upwards, up to the upper face of the floor 13. The front flank of the profile 14 is extended rearwards, at the level of the upper face of the floor 13, by a horizontal edge 15 which ends in a flange 16 oriented downwards. The edge 15 is thus cleared and accessible both from the bottom and from the rear in the direction of travel of the vehicle.

L'organe d'accrochage 12 comprend une tige 17 montée coulissante à l'intérieur d'un tube 18 fixé au deux longerons 4, 5 de chaque moitié de châssis 1. A son extrémité inférieure débordant du tube 18, la tige 17 présente un trou borgne taraudé dans lequel est vissée une tige filetée 19 portant à son extrémité inférieure une patte de préhension 20 munie d'un rebord 21 tourné vers le haut. Un écrou 22 permet de bloquer la tige filetée 19 par rapport à la tige 17.The attachment member 12 comprises a rod 17 slidingly mounted inside a tube 18 fixed to the two side members 4, 5 of each half of the chassis 1. At its lower end projecting from the tube 18, the rod 17 has a tapped blind hole into which is screwed a threaded rod 19 carrying at its lower end a gripping tab 20 provided with a flange 21 facing upwards. A nut 22 makes it possible to block the threaded rod 19 relative to the rod 17.

Le tube 18 est fixé à la moitié de châssis 1 à l'aide de deux colliers de serrage 23 (voir 2,3,4) dont chacun embrasse l'un des deux longerons 4, 5 de la moitié de châssis 1.The tube 18 is fixed to the half of the frame 1 using two clamps 23 (see 2,3,4) each of which embraces one of the two side members 4, 5 of the half of the frame 1.

Selon la fig. 3, la tige 17 est sollicitée vers le bas par rapport au tube 18 par'un ressort de compression 24 intercalé entre un épaulement que présente la tige 17 à l'intérieur du tube 18 et un bouchon 26 fixé à l'extrémité supérieure du tube 18 et traversé par l'extrémité supérieure de la tige 17. Un excentrique 27 est articulé par un axe transversal 28 sur l'extrémité supérieure de la tige 17, au-dessus du bouchon 26, de manière que la surface périphérique de l'excentrique 27 coopère à la manière d'une came avec le bouchon 26. Une manette de manoeuvre 29 est fixée à l'excentrique 27 de manière à permettre la rotation de ce dernier. La manette 29 est fixée à l'excentrique 27 de telle manière qu'elle se trouve sensiblement dans le prolongement du tube 18 lorsque l'axe 28 de l'excentrique 27 se trouve dans sa position la plus proche du bouchon 26 et soit rabattue contre le tube 18 lorsque l'axe 28 de l'excentrique 27 se trouve dans sa position la plus éloignée du bouchon 26. La manette 29 présente un profil transversal en arc de cercle adapté au profil circulaire du tube 18, de manière qu'en position rabattue contre le tube-18, la manette 27 s'emboîte sur une partie de la section du tube 18. Une poignée 30 fixée à la manette 29 facilite la manoeuvre de cette dernière.According to fig. 3, the rod 17 is biased downward relative to the tube 18 by a compression spring 24 interposed between a shoulder which the rod 17 has inside the tube 18 and a plug 26 fixed to the upper end of the tube 18 and crossed by the upper end of the rod 17. An eccentric 27 is articulated by a transverse axis 28 on the upper end of the rod 17, above the plug 26, so that the peripheral surface of the eccentric 27 cooperates in the manner of a cam with the plug 26. An operating lever 29 is fixed to the eccentric 27 so as to allow the latter to rotate. The handle 29 is fixed to the eccentric 27 so that it is substantially in the extension of the tube 18 when the axis 28 of the eccentric 27 is in its position closest to the plug 26 and is folded against the tube 18 when the axis 28 of the eccentric 27 is in its position furthest from the plug 26. The handle 29 has a transverse profile in an arc of a circle adapted to the circular profile of the tube 18, so that in position folded back against the tube-18, the handle 27 fits over part of the section of the tube 18. A handle 30 fixed to the handle 29 facilitates the operation of the latter.

Dans la position des organes d'accrochage 12 suivant les fig. 1 et 2, les pattes de préhension 20 sont accrochées en dessous du bord 15 du profil de retenue 14 encastré dans le plancher 13, les pattes de préhension 20 étant serrées vers le haut contre le bord 15 du profilé de retenue 14 sous l'action des excentriques 27 tournés de manière que les manettes 27 soient rabattues contre les tubes 18. Les organes d'accrochage 12 bloquent ainsi le fauteuil roulant sur le plancher 13.In the position of the fastening members 12 according to FIGS. 1 and 2, the gripping tabs 20 are hooked below the edge 15 of the retaining profile 14 embedded in the floor 13, the gripping tabs 20 being clamped upwards against the edge 15 of the retaining profile 14 under the action eccentrics 27 rotated so that the levers 27 are folded against the tubes 18. The fastening members 12 thus block the wheelchair on the floor 13.

La fig. 4 représente un organe d'accrochage 12 en position hors d'action, c'est-à-dire dans la position dans laquelle la patte de préhension 20 est relevée au-dessus de la surface du plancher 13 pour permettre la circulation du fauteuil roulant sur le plancher 13. Dans cette position, la tige 17 est relevée par rapport au tube 18 de manière que l'excentrique 27 se trouve à distance au-dessus du bouchon 26 et la tige 17 est immobilisée dans cette position par rapport au tube 18, à l'encontre de l'action du ressort 24, par la manette 29 rabattue contre le tube 18 dont l'extrémité libre, tournée vers le bas, est engagée depuis le haut derrière une patte d'accrochage 31 ouverte vers le haut, fixée au tube 18 à proximité de son extrémité supérieure.Fig. 4 shows a fastening member 12 in the inactive position, that is to say in the position in which the gripping tab 20 is raised above the surface of the floor 13 to allow the movement of the wheelchair on the floor 13. In this position, the rod 17 is raised relative to the tube 18 so that the eccentric 27 is at a distance above the plug 26 and the rod 17 is immobilized in this position relative to the tube 18 , against the action of the spring 24, by the lever 29 folded against the tube 18, the free end of which, facing downwards, is engaged from the top behind a hooking tab 31 open upwards, fixed to the tube 18 near its upper end.

Le fauteuil roulant est équipé d'une ceinture de sécurité à trois points, du type à enrouleur à inertie. L'enrouleur à inertie 32 est fixé à l'extrémité inférieure d'une des colonnes 11 qui est prolongée vers le haut au-dela du dossier 10. La sangle 33 de la ceinture s'étend depuis l'enrouleur 32 vers le haut jusqu'à un renvoi 34 monté sur l'extrémité supérieure de la colonne 11 plus haute. L'autre extrémité de la sangle 33 et la boucle de verrouillage 35 de la ceinture sont fixées respectivement aux organes d'accrochage 12 situés sur les deux côtés opposés du fauteuil roulant. Pour pouvoir déporter vers l'arrière ces deux points de fixation, une plaque 36 (non représentée sur les fig. 3 et 4) soudée à chaque tube 18 s'étend en direction du dossier 10 vers l'arrière à partir du tube-18, lesdites plaques 36 présentant, au voisinage de leur extrémité arrière libre, les deux points de fixation 37 inférieurs pour la ceinture, c'est-àdire pour la sangle 33 et pour la boucle 35.The wheelchair is equipped with a three-point seat belt, of the inertia reel type. The inertia reel 32 is fixed to the lower end of one of the columns 11 which is extended upwards beyond the backrest 10. The strap 33 of the belt extends from the reel 32 upwards to 'to a reference 34 mounted on the upper end of the higher column 11. The other end of the strap 33 and the locking loop 35 of the belt are respectively fixed to the fastening members 12 located on the two opposite sides of the wheelchair. In order to be able to offset these two fixing points to the rear, a plate 36 (not shown in FIGS. 3 and 4) welded to each tube 18 extends in the direction of the backrest 10 backwards from the tube-18 , said plates 36 having, in the vicinity of their free rear end, the two lower attachment points 37 for the belt, that is to say for the strap 33 and for the buckle 35.

L'occupant du fauteuil roulant peut, sans aucune aide, s'attacher lui-même au fauteuil, en bouclant la ceinture de sécurité, et ancrer le fauteuil au plancher du véhicule. Il suffit que l'occupant du fauteuil dirige ce dernier, les manettes 29 se trouvant à la position selon la fig. 4, c'est-à-dire les pattes 20 étant relevées au-dessus du plancher 13, jusqu'au voisinage de l'emplacement d'ancrage au plancher (profilé 14). Il soulève ensuite les manettes 29 pour les dégager des pattes 31 et les rabat vers le haut, de sorte que les tiges 17 descendent, sous l'effet des ressorts 24 jusqu'à ce que les pattes de préhension 20 portent sur le plancher 23. Si les pattes de préhension 20 se trouvaient déjà au-dessus du profilé de retenue 14, elles pénètrent directement dans ce dernier. Sinon, un léger déplacement du fauteuil permet de les engager dans ce profilé. Ensuite, l'occupant fait légèrement avancer le fauteuil, de manière que les pattes de préhension 20 s'engagent en dessous du rebord 15 du profilé 14, et rabat alors les manettes 29 vers le bas à la position selon les fig. 1 et 2, de sorte que les excentriques 27 soulèvent les tiges 17, ce qui serre les pattes de préhension 20 sous le rebord 15 du profilé 14. Le fauteuil est ainsi ancré au plancher 13.The occupant of the wheelchair can, without any help, attach himself to the wheelchair, by fastening the seat belt, and anchor the wheelchair to the floor of the vehicle. It suffices that the occupant of the chair directs the latter, the levers 29 being in the position according to FIG. 4, that is to say the tabs 20 being raised above the floor 13, up to the vicinity of the location for anchoring to the floor (profile 14). It then lifts the levers 29 to release them from the lugs 31 and flaps them upwards, so that the rods 17 descend, under the effect of the springs 24 until the gripping lugs 20 bear on the floor 23. If the gripping tabs 20 were already above the retaining profile 14, they penetrate directly into the latter. Otherwise, a slight movement of the chair allows them to be engaged in this profile. Then, the occupant slightly advances the chair, so that the gripping tabs 20 engage below the edge 15 of the profile 14, and then fold the levers 29 down to the position according to FIGS. 1 and 2, so that the eccentrics 27 raise the rods 17, which grips the gripping tabs 20 under the flange 15 of the profile 14. The chair is thus anchored to the floor 13.

Pour détacher le fauteuil du plancher 13, l'occupant du fauteuil rabat les manettes 29 vers le haut dans la position selon la fig. 3, de sorte que les excentriques 27 permettent aux tiges 17 de descendre, sous l'effet des ressorts 24. Les pattes de préhension 20 se dégagent ainsi du rebord 15 du profilé de retenue 14. L'occupant fait légèrement reculer le fauteuil et tire ensuite les manettes 29 vers le haut avant de les rabattre à la position de la fig. 4, et les verrouiller sur les pattes d'accrochage 31. Les pattes de préhension 20 sont ainsi retenues au-dessus du plancher 13 et le fauteuil peut circuler librement.To detach the chair from the floor 13, the occupant of the chair folds the levers 29 upwards into the position according to FIG. 3, so that the eccentrics 27 allow the rods 17 to descend, under the effect of the springs 24. The gripping tabs 20 thus emerge from the edge 15 of the retaining profile 14. The occupant moves the chair slightly back and pulls then the handles 29 upwards before folding them back to the position of FIG. 4, and lock them on the attachment tabs 31. The gripping tabs 20 are thus retained above the floor 13 and the chair can move freely.

Il va de soi que de nombreuses modifications et variantes peuvent être apportées au dispositif de sécurité tel que décrit ci-dessus. Ainsi, les tubes 18 des organes d'accrochage 12 pourraient être fixés aux moitiés de châssis 1 du fauteuil par des moyens autres que les colliers de serrage.23, par exemple à demeure par soudure. Les colliers 23.présentent néanmoins l'avantage de permettre une fixation amovible sur des fauteuil de modèles différents, les colliers 23 étant réglables suivant l'axe des tubes 18 grâce à des coulisseaux 38 pouvant être bloqués par des vis 39 dans des glissières 40 solidaires des tubes 18 (voir fig. 3).It goes without saying that many modifications and variants can be made to the safety device such as described above. Thus, the tubes 18 of the fastening members 12 could be fixed to the chassis halves 1 of the chair by means other than the clamps. 23, for example permanently by welding. The collars 23. nevertheless have the advantage of allowing removable fixing on armchairs of different models, the collars 23 being adjustable along the axis of the tubes 18 by means of sliders 38 which can be blocked by screws 39 in integral slides 40 tubes 18 (see fig. 3).

Par ailleurs, on peut également concevoir, pour l'actionnement des organes d'accrochage 12, des moyens autres que les excentriques 27 et les manettes 29, par exemple des moyens à vis, bien que les moyens représentés permettent une manoeuvre particulièrement simple et rapide.Furthermore, it is also possible to design, for the actuation of the fastening members 12, means other than the eccentrics 27 and the levers 29, for example screw means, although the means shown allow a particularly simple and rapid maneuver. .

Le ressort 24 qui sollicite la tige 17 vers le bas par rapport au tube 18 n'est pas indispensable, le poids de la tige 17 étant généralement suffisant pour permettre à cette dernière de.coulisser vers le bas dès qu'elle a été débloquée à son extrémité supérieure.The spring 24 which urges the rod 17 downwards relative to the tube 18 is not essential, the weight of the rod 17 being generally sufficient to allow the latter to slide down as soon as it has been released. its upper end.

Dans le mode de réalisation illustré par la fig. 5, le mécanisme d'ancrage du fauteuil roulant au plancher 13 du véhicule comprend deux supports de boucle de verrouillage 38 formés chacun d'un montant flexible et élastique 39 dont une extrémité est fixée, par exemple à l'aide d'une vis 40, au plancher 13 et dont l'autre extrémité porte une boucle de verrouillage 41. Ces supports de boucle de verrouillage sont analogues à ceux utilisés sur les véhicules automobiles pour le bouclage d'une ceinture de sécurité. Les deux montants 39 sont fixés au plancher 13 à une distance réciproque supérieure à la voie des roues avant 7 du fauteuil. Chaque montant 39 est constitué par exemple par au moins un câble métallique dont la flexibilité et l'élasticité permettent au montant de fléchir au passage des roues d'un fauteuil roulant et de reprendre ensuite sa position initiale, de préférence sensiblement verticale.In the embodiment illustrated in FIG. 5, the mechanism for anchoring the wheelchair to the floor 13 of the vehicle comprises two locking loop supports 38 each formed of a flexible and elastic upright 39, one end of which is fixed, for example using a screw 40 , to the floor 13 and the other end of which carries a locking loop 41. These locking loop supports are similar to those used on motor vehicles for fastening a seat belt. The two uprights 39 are fixed to the floor 13 at a reciprocal distance greater than the track of the front wheels 7 of the chair. Each upright 39 is constituted for example by at least one metal cable whose flexibility and elasticity allow the upright to flex when the wheels of a wheelchair pass and then return to its initial position, preferably substantially vertical.

Au lieu d'être fixés chacun l'aide d'une vis 40 au plancher 13, chaque support de boucle 38 peut également être fixé dans une rainure transversale du plancher, analogue au profilé de retenue 14 du mode de réalisation des fig. 1 à 4. Cela permet une adaptation extrêmement simple à des fauteuils de largeurs différentes.Instead of being each fixed with a screw 40 to the floor 13, each loop support 38 can also be fixed in a transverse groove in the floor, similar to the retaining profile 14 of the embodiment of FIGS. 1 to 4. This allows an extremely simple adaptation to armchairs of different widths.

Le fauteuil roulant est équipé de deux sangles 42 et 43 portant chacune à son extrémité libre une languette 44 susceptible d'être verrouillée de façon libérable dans l'une des boucles de verrouillage 41. Les deux sangles 42 et 43 passent dans deux fentes 45 ménagées dans un berceau 46 à profil en U dont les deux ailes 47 sont fixées aux deux longerons supérieurs 5 du châssis du fauteuil roulant et dont l'âme 48 horizontale s'étend en dessous de l'assise 8. Les deux fentes 45 sont ménagées dans le berceau 46 au voisinage des angles opposés entre les ailes 47 et l'âme 48, c'est-à-dire sur les deux côtés latéraux du fauteuil roulant. Chaque fente 45 présente une forme telle que la languette 44 fixée à l'extrémité libre de la sangle 42 ou 43, respectivement, ne puisse pas traverser la fente 45 et se trouve donc retenue à l'extérieur du berceau 46.The wheelchair is equipped with two straps 42 and 43 each carrying at its free end a tongue 44 capable of being releasably locked in one of the locking loops 41. The two straps 42 and 43 pass through two slots 45 provided in a cradle 46 with a U-shaped profile, the two wings 47 of which are fixed to the two upper side members 5 of the chassis of the wheelchair and the horizontal core 48 of which extends below the seat 8. The two slots 45 are provided in the cradle 46 in the vicinity of the opposite angles between the wings 47 and the core 48, that is to say on the two lateral sides of the wheelchair. Each slot 45 has a shape such that the tongue 44 fixed to the free end of the strap 42 or 43, respectively, cannot pass through the slot 45 and is therefore retained outside the cradle 46.

L'âme 48 du berceau 46 qui peut être de préférence télescopique pour permettre l'adaptation du berceau sur des fauteuils de largeurs différentes porte ou constitue une glissière transversale 49 dans laquelle est monté le châssis 50 d'un enrouleur automatique de sangle 51 du type rétracteur. De tels enrouleurs sont déjà utilisés pour des ceintures de sécurité et présentent la particularité d'être équipés d'un système à cliquet qui n'entre en action qu'après le déroulement d'une longueur prédéterminée de sangle et après relâchement subséquent de la sangle, pour s'opposer ensuite au déroulement ultérieur de la sangle en permettant cependant le réenroulement de la sangle, sous l'action du ressort de rappel de l'enrouleur, dès que la sangle est relâchée.The core 48 of the cradle 46 which may preferably be telescopic to allow the adaptation of the cradle on armchairs of different widths carries or constitutes a transverse slide 49 in which is mounted the chassis 50 of an automatic strap winder 51 of the type retractor. Such retractors are already used for seat belts and have the particularity of being fitted with a ratchet system which only comes into action after the unwinding of a predetermined length of strap and after subsequent release of the strap , to then oppose the subsequent unwinding of the strap, however allowing the rewinding of the strap, under the action of the return spring of the reel, as soon as the strap is released.

L'extrémité de la sangle 42 opposée à la languette 44 est fixée au carter 50 de l'enrouleur 51. L'extrémité de la sangle 43 opposée à la languette 44 est enroulée sur l'axe 52 de l'enrouleur 51.The end of the strap 42 opposite the tongue 44 is fixed to the casing 50 of the reel 51. The end of the strap 43 opposite the tongue 44 is wound on the axis 52 of the reel 51.

Le fauteuil roulant est en outre équipé d'une ceinture de sécurité pour retenir l'occupant du fauteuil sur ce dernier. On reconnaît sur la figure 5 une sangle 33 dont une extrémité est fixée en 53 à l'une des ailes 47 du berceau 46 et dont l'autre extrémité porte une languette 54 susceptible d'être verrouillée de façon amovible dans une boucle 35 fixée en 55 à l'autre aile 47 du berceau 46.The wheelchair is also fitted with a seat belt to restrain the occupant of the wheelchair. We recognize in FIG. 5 a strap 33, one end of which is fixed at 53 to one of the wings 47 of the cradle 46 and the other end of which carries a tongue 54 capable of being releasably locked in a loop 35 fixed at 55 to the other wing 47 of the cradle 46.

En vue de l'ancrage du fauteuil roulant au plancher du véhicule de transport, l'occupant du fauteuil roulant manoeuvre ce dernier de manière à l'amener dans une position telle que les deux supports de boucle 38 soient situés sur les deux côtés opposés du fauteuil, entre les grandes roues 6 et les petites roues 7, ce qui ne présente pas de difficulté dans la mesure où les montants 39 sont flexibles et s'écartent. Lorsque le fauteuil occupe cette position par rapport aux supports de boucle 38, l'occupant du fauteuil exerce d'abord une traction vers l'extérieur (vers la gauche sur la figure 5) sur la languette 44 de la sangle 42, cette languette 44 étant, tout comme la languette 44'de la sangle 43, appliquée sous l'effet du ressort de rappel de l'enrouleur 51 de l'extérieur contre le berceau 46 de manière à être située devant la fente 45. Sous l'effet de cette traction exercée sur la sangle 42 qui est de longueur fixe, l'enrouleur 51 se déplace (vers la gauche sur la figure-5) dans la glissière 49, de sorte qu'une longueur correspondante de la sangle 43 se trouve déroulée de l'axe d'enroulement 52 de l'enrouleur 51 dont le cliquet n'entre pas encore en action. Après verrouillage de la languette 44 de la sangle 42 dans la boucle 41 (de gauche sur la figure 5), l'occupant du fauteuil saisit la languette 44 de la sangle 43 et exerce sur cette languette une traction vers l'extérieur (vers la droite sur la figure 5) de manière à dérouler de l'axe 52 une longueur suffisante de la sangle 43 pour permettre le verrouillage de la languette 44 de cette sangle dans la boucle 41 (de droite sur la figure 5). Lorsque l'occupant relâche ensuite la languette 44 de la sangle 43, verrouillée dans la boucle 41, l'enrouleur 51 tend la sangle 43 en réenroulant la longueur excédentaire de cette sangle. Il suffit alors à l'occupant du siège de manoeuvrer ce dernier légèrement en avant et en arrière de manière que le siège adopte automatiquement, sous l'effet de la traction exercée par l'enrouleur 51 sur les deux sangles, la position optimale par rapport aux deux supports de boucle 38, c'est-à-dire la position dans laquelle la longueur des deux sangles 42 et 43 en dehors du berceau 46 est minimale.With a view to anchoring the wheelchair to the floor of the transport vehicle, the occupant of the wheelchair maneuvers the latter so as to bring it into a position such that the two buckle supports 38 are located on the two opposite sides of the armchair, between the large wheels 6 and the small wheels 7, which does not present any difficulty insofar as the uprights 39 are flexible and deviate. When the chair occupies this position relative to the buckle supports 38, the occupant of the chair first exerts traction towards the outside (towards the left in FIG. 5) on the tongue 44 of the strap 42, this tongue 44 being, like the tongue 44 ' of the strap 43, applied under the effect of the return spring of the reel 51 from the outside against the cradle 46 so as to be located in front of the slot 45. Under the effect of this traction exerted on the strap 42 which is of fixed length, the reel 51 moves (to the left in FIG. 5) in the slide 49, so that a corresponding length of the strap 43 is unwound from the 'winding axis 52 of the reel 51 whose pawl does not yet come into action. After locking the tongue 44 of the strap 42 in the loop 41 (on the left in FIG. 5), the occupant of the chair grasps the tongue 44 of the strap 43 and exerts on this tongue a pull towards the outside (towards the right in Figure 5) so as to unwind from the axis 52 a sufficient length of the strap 43 to allow the locking of the tongue 44 of this strap in the loop 41 (on the right in Figure 5). When the occupant then releases the tongue 44 of the strap 43, locked in the loop 41, the reel 51 tightens the strap 43 by rewinding the excess length of this strap. he the occupant of the seat then suffices to maneuver the latter slightly forward and backward so that the seat automatically adopts, under the effect of the traction exerted by the reel 51 on the two straps, the optimal position relative to the two buckle supports 38, that is to say the position in which the length of the two straps 42 and 43 outside the cradle 46 is minimum.

L'occupant au fauteuil s'attache ensuite à ce dernier en bouclant la ceinture de sécurité (33, 35, 54) s'il ne l'a pas déjà fait auparavant.The occupant in the wheelchair then attaches to the latter by fastening the seat belt (33, 35, 54) if he has not already done so before.

Pour supprimer l'ancrage du fauteuil roulant au plancher du véhicule, l'occupant du fauteuil déverrouille simplement les deux languettes 44 des boucles 41, soit simultanément, soit successivement. Dans un cas comme dans l'autre, l'enrouleur 51 rappelle les deux sangles 42 et 43 vers l'intérieur du berceau 46 jusqu'à l'arrêt des languettes 44 devant les fente 45 du berceau 46. L'occupant du fauteuil peut alors manoeuvrer ce dernier librement.To remove the anchoring of the wheelchair to the vehicle floor, the occupant of the wheelchair simply unlocks the two tabs 44 of the loops 41, either simultaneously or successively. In one case as in the other, the reel 51 recalls the two straps 42 and 43 towards the inside of the cradle 46 until the tongues 44 stop in front of the slots 45 of the cradle 46. The occupant of the wheelchair can then maneuver the latter freely.

Le mode de réalisation suivant la fig. 5 peut également recevoir de nombreuses modifications.The embodiment according to FIG. 5 can also receive numerous modifications.

Ainsi, chaque boucle 41, au lieu d'être disposée à l'extrémité d'un montant flexible 39, pourrait également être disposée à l'extrémité supérieure commune de deux montants flexibles dont les extrémités inférieures sont fixées au plancher 13 du véhicule en deux points espacés suivant une droite parallèle à l'axe longitudinal du fauteuil à ancrer.Thus, each loop 41, instead of being disposed at the end of a flexible upright 39, could also be disposed at the common upper end of two flexible uprights whose lower ends are fixed to the floor 13 of the vehicle in two points spaced along a straight line parallel to the longitudinal axis of the chair to be anchored.

L'enrouleur rétracteur unique pour les deux sangles pourrait également être remplacé par deux enrouleurs fixes, par exemple du type à inertie, agissant chacun sur l'une des deux sangles. On pourrait par ailleurs prévoir également des sangles sans enrouleur, mais le réglage de longueur manuel des sangles impliquerait alors des manoeuvres fastidieuses.The single retractor reel for the two straps could also be replaced by two fixed reels, for example of the inertia type, each acting on one of the two straps. We could also provide straps without reel, but the manual length adjustment of the straps would then involve tedious maneuvers.

La ceinture de sécurité pour attacher l'occupant du fauteuil à ce dernier peut être du type à deux points ou trois points, avec ou sans enrouleur, mais l'utilisation d'une ceinture à trois points et à enrouleur procure une meilleure protection, facilite le bouclage de la ceinture et donne à l'occupant du fauteuil une plus grande liberté de mouvement. Les montants flexibles et élastiques 39 peuvent être constitués, comme déjà mentionné, par des câbles métalliques ou par des câbles, sangles, cordons en d'autres matériaux, par exemple textiles, qui peuvent être entourés d'une gaine élastique, par exemple en matière plastique. La distance réciproque entre les montants portant les boucles pour l'ancrage d'un fauteuil est de préférence supérieure à la largeur du châssus du fauteuil, mais inférieure à la voie des grandes roues du fauteuil. De ce fait, les montants viennent se placer entre les grandes roues et le châssis du fauteuil et les grandes roues n'interfèrent pas avec le mécanisme d'ancrage dont l'enrouleur (ou les enrouleurs) et les sangles sont'de préférence situés dans un plan vertical transversal passant sensiblement par le centre de gravité du fauteuil roulant.The seat belt for attaching the occupant to the chair may be of the two-point or three-point type, with or without a retractor, but the use of a three-point retractable belt provides better protection, facilitates fastening the belt and giving occupying the chair more freedom of movement. The flexible and elastic uprights 39 can be constituted, as already mentioned, by metallic cables or by cables, straps, cords made of other materials, for example textiles, which can be surrounded by an elastic sheath, for example of material plastic. The reciprocal distance between the uprights carrying the loops for anchoring a chair is preferably greater than the width of the chair frame, but less than the track of the large wheels of the chair. As a result, the uprights are placed between the large wheels and the frame of the chair and the large wheels do not interfere with the anchoring mechanism whose reel (or reels) and the straps are preferably located in a transverse vertical plane passing substantially through the center of gravity of the wheelchair.

Le mode de réalisation des fig. 1 à 4 convient plus particulièrement au montage à demeure sur des fauteuils roulants pour des personnes utilisant systématiquement un même véhicule de transport.The embodiment of FIGS. 1 to 4 is more particularly suitable for permanent mounting on wheelchairs for people systematically using the same transport vehicle.

Le mode de réalisation de la fig. 5 est par contre destiné plus spécialement à l'adaptation sur des fauteuils roulants de personnes n'utilisant pas systématiquement un véhicule de transport, cette adaptation étant extrêmement simple et rapide, quelle que soit la largeur des fauteuils.The embodiment of FIG. 5 is on the other hand intended more specifically for the adaptation on wheelchairs of people not systematically using a transport vehicle, this adaptation being extremely simple and rapid, whatever the width of the armchairs.
