Definitions

  • the present invention relates to the field of stretchers, including rigid devices adapted to wear a hood and to be slid between a stretcher headrest frame and a mattress, to the hoods for stretcher headrest, and protection systems that include a rigid device and a hood.
  • a protection system is constituted by a hood that is attached to the stretcher so as to be disposed above the patient's head.
  • the hood comprises, in addition to the protective surface (typically made of fabric) and the means of deployment of this surface (typically made by whales whose ends meet in two hinges defining a deployment axis of the protective surface), fastening means which allow attachment of the hood to the stretcher (in general, the two side barriers which extend along the stretcher to the headrest).
  • stretchers are standardized, there are stretchers of different types and sizes (especially with regard to the width of the stretcher and also the distance between the side barriers of the headrest) . It follows that even if the top is designed for a stretcher model, it can be used for similar models, but the structural differences between the model of the stretcher used and the model of the stretcher design lead to more or less long term , and according to the importance of these differences, mechanical constraints on the hood and thus increased risks of breakage. For example, a width difference of the stretcher (transverse direction of the stretcher) causes a tension on the transverse spacing of the protective surface of the hood and deployment means of the protective surface. It may even be impossible to attach the hood to the stretcher if the structural differences between the stretcher and the design model are too great or if the shape of the place where the stretcher should be attached is incompatible with the shape of the fastening means.
  • the fixed elements of the frame of the stretcher being in the longitudinal zone of the headrest (such as the longitudinal bars carrying the handling handles of the stretcher and possibly the side rails) must be adjacent to the mattress of the headrest which prohibits both attachment to the frame of the headrest for lack of space and attachment to the fixed elements of the stretcher because of the risk of shock between the head of the patient resting on the headrest and the hood in case the headrest should be raised.
  • attachment means used require a more or less long and tedious handling for ambulance to attach the hood to the stretcher.
  • the present invention aims to provide a new protection system which, preferably, does not have any of the aforementioned drawbacks.
  • the invention relates to a rigid device adapted to wear a hood and to be slid between a frame of a headrest of a stretcher and a mattress resting on the frame so as to maintain the top over the headrest, the device comprising a plate and a rib which is projecting from the plate and which is adapted to abut against a transverse element of the armature when the device is slid in a direction parallel to the longitudinal direction of the stretcher.
  • the hood is no longer attached to the stretcher but to a substantially flat rigid device which is secured to the stretcher on the one hand by the weight of the mattress and on the other by its abutment against the frame of the headrest. Therefore, the only dimension of the stretcher which is a mandatory feature for the rigid device is the width of the mattress of the headrest, which makes the rigid device usable for any model of stretcher having this characteristic.
  • the used hood being connected to the rigid device for which it was designed, it does not undergo mechanical stress other than the constraints defined during its design.
  • the hood being fixed to the rigid device which is at the level of the headrest, there are no mechanical constraints related to the distance, taken in the longitudinal direction of the stretcher, between the protective surface and the fixing means.
  • the protective surface of the hood and the plate of the rigid device can pass between the mattress of the headrest and the fixed elements of the frame of the stretcher, which allows an indirect fixing of the hood to the stretcher in the area of the headrest.
  • the rigid device (even accompanied by a hood) can be implemented by simply sliding longitudinally between the mattress and the frame of the headrest.
  • the limitation of the sliding of the rigid device by the abutment against the transverse element of the frame of the headrest makes it possible to avoid the rigid device and the hood of sinking further towards the base of the headrest (at its junction with the rest of the stretcher) when it is raised and thus to avoid disturbing the patient.
  • the rigid device and the plate comprise a longitudinal direction which corresponds to the longitudinal direction of the stretcher when the rib is in abutment against the transverse element of the frame of the headrest.

Description

SYSTÈME DE PROTECTION OUR UN BRANCARD  PROTECTION SYSTEM FOR A BRANCARD
La présente invention se rapporte au domaine des brancards, et notamment à des dispositifs rigides adaptés à porter une capote et à être glissés entre une armature de têtière de brancard et un matelas, aux capotes pour têtière de brancard, et aux systèmes de protection qui comprennent un dispositif rigide et une capote .  The present invention relates to the field of stretchers, including rigid devices adapted to wear a hood and to be slid between a stretcher headrest frame and a mattress, to the hoods for stretcher headrest, and protection systems that include a rigid device and a hood.
On connaît des systèmes de protection permettant de protéger la tête d'un patient se trouvant sur un brancard quand ce dernier se trouve notamment à l'extérieur (protection contre le vent, la pluie...) . Classiquement, un tel système de protection est constitué par une capote qui est fixée au brancard de façon à être disposée au-dessus de la tête du patient . La capote comprend, outre la surface de protection (typiquement réalisée en tissu) et les moyens de déploiement de cette surface (typiquement réalisés par des baleines dont les extrémités se rejoignent en deux charnières définissant un axe de déploiement de la surface de protection) , des moyens de fixation qui permettent une fixation de la capote au brancard (de façon générale, aux deux barrières latérales qui s'étendent le long du brancard jusqu'à la têtière).  Protective systems are known to protect the head of a patient lying on a stretcher when the latter is especially outside (protection against the wind, rain ...). Conventionally, such a protection system is constituted by a hood that is attached to the stretcher so as to be disposed above the patient's head. The hood comprises, in addition to the protective surface (typically made of fabric) and the means of deployment of this surface (typically made by whales whose ends meet in two hinges defining a deployment axis of the protective surface), fastening means which allow attachment of the hood to the stretcher (in general, the two side barriers which extend along the stretcher to the headrest).
Cependant, ces systèmes de protection présentent plusieurs inconvénients .  However, these protection systems have several disadvantages.
D'une part, même si pour de nombreuses caractéristiques, les brancards sont normalisés, il existe des brancards de différents types et de différentes dimensions (notamment en ce qui concerne la largeur du brancard et également la distance séparant les barrières latérales de la têtière). Il s'ensuit que même si la capote est conçue pour un modèle de brancard, elle peut être utilisée pour des modèles proches, mais les différences structurelles entre le modèle du brancard utilisé et le modèle du brancard de conception entraînent à plus ou moins long terme, et selon l'importance de ces différences, des contraintes mécaniques sur la capote et donc des risques accrus de casse . Par exemple, un écart de largeur du brancard (direction transversale du brancard) entraîne une tension sur l'écartement transversal de la surface de protection de la capote et des moyens de déploiement de la surface de protection. Il peut même être impossible de fixer la capote au brancard si les différences structurelles entre ce dernier et le modèle de conception sont trop importantes ou si la forme du lieu du brancard où devraient se fixer la capote est incompatible avec la forme des moyens de fixation . On the one hand, even if for many features, stretchers are standardized, there are stretchers of different types and sizes (especially with regard to the width of the stretcher and also the distance between the side barriers of the headrest) . It follows that even if the top is designed for a stretcher model, it can be used for similar models, but the structural differences between the model of the stretcher used and the model of the stretcher design lead to more or less long term , and according to the importance of these differences, mechanical constraints on the hood and thus increased risks of breakage. For example, a width difference of the stretcher (transverse direction of the stretcher) causes a tension on the transverse spacing of the protective surface of the hood and deployment means of the protective surface. It may even be impossible to attach the hood to the stretcher if the structural differences between the stretcher and the design model are too great or if the shape of the place where the stretcher should be attached is incompatible with the shape of the fastening means.
D'autre part, notamment dans le cas où la capote est destinée à être fixée aux barrières latérales, des contraintes mécaniques supplémentaires existent du fait de la distance, prise dans le sens longitudinal du brancard, entre la surface de protection qui se trouve exclusivement au niveau de la têtière et les moyens de fixation qui se trouvent au niveau des barrières latérales (celles-ci pouvant, dans certains modèles de brancard, se trouver complètement hors de la zone de la têtière) .  On the other hand, especially in the case where the hood is intended to be fixed to the side rails, additional mechanical stresses exist because of the distance, taken in the longitudinal direction of the stretcher, between the protective surface which is exclusively at the level of the headrest and fastening means which are at the side barriers (they may, in some models stretcher, be completely outside the area of the headrest).
D'autre part, quand la têtière est relevable, les éléments fixes de l'armature du brancard se trouvant dans la zone longitudinale de la têtière (tels que les barres longitudinales portant les poignées de manipulation du brancard et éventuellement les barrières latérales) doivent être adjacents au matelas de la têtière ce qui interdit à la fois une fixation à l'armature de la têtière par manque de place et une fixation aux éléments fixes du brancard du fait du risque de choc entre la tête du patient reposant sur la têtière et la capote dans le cas où la têtière devrait être relevée.  On the other hand, when the headrest is liftable, the fixed elements of the frame of the stretcher being in the longitudinal zone of the headrest (such as the longitudinal bars carrying the handling handles of the stretcher and possibly the side rails) must be adjacent to the mattress of the headrest which prohibits both attachment to the frame of the headrest for lack of space and attachment to the fixed elements of the stretcher because of the risk of shock between the head of the patient resting on the headrest and the hood in case the headrest should be raised.
Enfin, les moyens de fixation utilisés nécessitent une manipulation plus ou moins longue et fastidieuse pour les ambulanciers afin de fixer la capote au brancard.  Finally, the attachment means used require a more or less long and tedious handling for ambulance to attach the hood to the stretcher.
La présente invention vise à réaliser un nouveau système de protection qui, de préférence, ne présente aucun des inconvénients précités . Selon un premier aspect, l'invention concerne un dispositif rigide adapté à porter une capote et à être glissé entre une armature d'une têtière d'un brancard et un matelas reposant sur l'armature de façon à maintenir la capote au-dessus de la têtière, le dispositif comprenant une plaque et une nervure qui est saillante de la plaque et qui est adaptée à venir en butée contre un élément transversal de l'armature quand le dispositif est glissé selon une direction parallèle à la direction longitudinale du brancard. The present invention aims to provide a new protection system which, preferably, does not have any of the aforementioned drawbacks. According to a first aspect, the invention relates to a rigid device adapted to wear a hood and to be slid between a frame of a headrest of a stretcher and a mattress resting on the frame so as to maintain the top over the headrest, the device comprising a plate and a rib which is projecting from the plate and which is adapted to abut against a transverse element of the armature when the device is slid in a direction parallel to the longitudinal direction of the stretcher.
Ainsi, la capote n'est plus fixée au brancard mais à un dispositif rigide essentiellement plan qui est solidarisé au brancard d'une part par le poids du matelas et d'autre part par sa mise en butée contre l'armature de la têtière. De ce fait, la seule dimension du brancard qui est une caractéristique impérative pour le dispositif rigide est la largeur du matelas de la têtière, ce qui rend le dispositif rigide utilisable pour tout modèle de brancard présentant cette caractéristique . De plus, la capote utilisée n'étant reliée qu'au dispositif rigide pour lequel elle a été conçue, elle ne subit pas de contrainte mécanique autre que les contraintes définies lors de sa conception. La capote étant fixée au dispositif rigide qui se trouve au niveau de la têtière, il n'y a pas de contraintes mécaniques liées à la distance, prise dans le sens longitudinal du brancard, entre la surface de protection et les moyens de fixation. Du fait de leur nature particulièrement mince, la surface de protection de la capote et la plaque du dispositif rigide peuvent passer entre le matelas de la têtière et les éléments fixes de l'armature du brancard, ce qui permet une fixation indirecte de la capote au brancard dans la zone de la têtière. Le dispositif rigide (même accompagné d'une capote) peut être mis en place par un simple coulissement longitudinal entre le matelas et l'armature de la têtière. Enfin, la limitation du coulissement du dispositif rigide par la mise en butée contre l'élément transversal de l'armature de la têtière permet d' éviter au dispositif rigide et à la capote de s'enfoncer plus vers la base de la têtière (au niveau de sa jonction avec le reste du brancard) quand celle-ci est relevée et donc d'éviter de gêner le patient. Thus, the hood is no longer attached to the stretcher but to a substantially flat rigid device which is secured to the stretcher on the one hand by the weight of the mattress and on the other by its abutment against the frame of the headrest. Therefore, the only dimension of the stretcher which is a mandatory feature for the rigid device is the width of the mattress of the headrest, which makes the rigid device usable for any model of stretcher having this characteristic. In addition, the used hood being connected to the rigid device for which it was designed, it does not undergo mechanical stress other than the constraints defined during its design. The hood being fixed to the rigid device which is at the level of the headrest, there are no mechanical constraints related to the distance, taken in the longitudinal direction of the stretcher, between the protective surface and the fixing means. Due to their particularly thin nature, the protective surface of the hood and the plate of the rigid device can pass between the mattress of the headrest and the fixed elements of the frame of the stretcher, which allows an indirect fixing of the hood to the stretcher in the area of the headrest. The rigid device (even accompanied by a hood) can be implemented by simply sliding longitudinally between the mattress and the frame of the headrest. Finally, the limitation of the sliding of the rigid device by the abutment against the transverse element of the frame of the headrest makes it possible to avoid the rigid device and the hood of sinking further towards the base of the headrest (at its junction with the rest of the stretcher) when it is raised and thus to avoid disturbing the patient.
Le dispositif rigide et la plaque comprennent une direction longitudinale qui correspond à la direction longitudinale du brancard quand la nervure est en butée contre l'élément transversal de l'armature de la têtière. Le dispositif rigide et la plaque comprennent une direction transversale qui est perpendiculaire à la direction longitudinale de la plaque. Le dispositif rigide et la plaque comprennent une direction verticale qui s'étend selon l'épaisseur de la plaque et qui est perpendiculaire aux directions longitudinale et transversale .  The rigid device and the plate comprise a longitudinal direction which corresponds to the longitudinal direction of the stretcher when the rib is in abutment against the transverse element of the frame of the headrest.

Selon un cinquième mode de réalisation, la nervure présente une échancrure afin d'éviter toute interaction avec des organes fixés à l'élément transversal de l'armature contre laquelle la nervure est en butée. De tels organes peuvent être des moyens de relèvement ou rabaissement de la têtière, tels que des crémaillères ou des vérins .  According to a fifth embodiment, the rib has a notch in order to avoid any interaction with members attached to the transverse element of the armature against which the rib is abutting. Such bodies may be means for raising or lowering the headrest, such as racks or jacks.
Selon un sixième mode de réalisation, la nervure comprend un orifice permettant, quand elle est en butée contre l'élément transversal de l'armature de la têtière, une fixation du dispositif rigide au brancard par le passage d'un élément de fixation (tel qu'une vis). Ce mode de réalisation permet de réaliser une fixation particulièrement sûre du dispositif rigide . According to a sixth embodiment, the rib comprises an orifice allowing, when it is in abutment against the transverse element of the frame of the headrest, a fixation of the rigid device to the stretcher by the passage of a fastening element (such that a screw). This embodiment makes it possible to achieve a particularly secure fixation of the rigid device.
Selon un septième mode de réalisation, une nervure supplémentaire est portée à l'extrémité libre de la nervure de façon à définir, avec cette dernière et la plaque, un logement pour l'élément transversal de l'armature de la têtière quand ce dernier est en butée contre la nervure .  According to a seventh embodiment, an additional rib is carried at the free end of the rib so as to define, with the latter and the plate, a housing for the transverse element of the armature of the headrest when the latter is in abutment against the rib.
Selon un huitième mode de réalisation, la nervure supplémentaire est une règle plate.  According to an eighth embodiment, the additional rib is a flat ruler.

Selon un quinzième mode de réalisation, la plaque comprend un orifice permettant, quand la nervure est en butée contre l'élément transversal de l'armature, une fixation du dispositif rigide au brancard par le passage d'un élément de fixation (tel qu'une vis). Ce mode de réalisation permet de réaliser une fixation particulièrement sûre du dispositif rigide. According to a fourteenth embodiment, the additional rib comprises an orifice allowing, when the rib is in abutment against the transverse element of the armature, an attachment of the rigid device to the stretcher by the passage of a fastening element (such as 'a screw) . This embodiment makes it possible to achieve a particularly secure attachment of the rigid device. According to a fifteenth embodiment, the plate comprises an orifice allowing, when the rib is in abutment against the transverse element of the armature, a fixation of the rigid device to the stretcher by the passage of a fastening element (such as a screw). This embodiment makes it possible to achieve a particularly secure attachment of the rigid device.
Selon un seizième mode de réalisation, la plaque a la forme d' un rectangle prolongé sur un côté transversal par un demi disque dont le diamètre est égal à la longueur des côtés transversaux. Le rectangle est destiné à être disposé du côté de la base de la têtière, et le demi-disque du côté du bord longitudinal libre de celle-ci .  According to a sixteenth embodiment, the plate has the shape of a rectangle extended on a transverse side by a half disk whose diameter is equal to the length of the transverse sides. The rectangle is intended to be disposed on the side of the base of the headrest, and the half-disc on the side of the free longitudinal edge thereof.
Selon un dix-septième mode de réalisation, le dispositif rigide comprend deux pattes qui sont saillantes de la face de la plaque opposée à celle portant la nervure . Les deux pattes sont disposées de façon à s'étendre de chaque côté de la têtière, entre cette dernière et des éléments fixes de l'armature du brancard, quand la nervure est en butée contre l'élément transversal de l'armature de la têtière. Les deux pattes sont adaptées à recevoir la capote. Selon ce mode de réalisation, en concevant des pattes s 'étendant verticalement au-delà du matelas, il est possible de fixer la capote aux deux pattes du dispositif rigide par l'intermédiaire des deux extrémités de baleines destinées à permettre le déploiement de la capote.  According to a seventeenth embodiment, the rigid device comprises two lugs which protrude from the face of the plate opposite to that carrying the rib. The two tabs are arranged so as to extend on each side of the headrest, between the latter and the fixed elements of the frame of the stretcher, when the rib is in abutment against the transverse element of the frame of the headrest . Both legs are adapted to receive the hood. According to this embodiment, by designing lugs extending vertically beyond the mattress, it is possible to attach the hood to the two legs of the rigid device via the two ends of whales intended to allow the deployment of the hood .
Selon un dix-huitième mode de réalisation, les deux pattes sont disposées symétriquement par rapport à un axe central longitudinal du dispositif rigide .  According to an eighteenth embodiment, the two tabs are arranged symmetrically with respect to a longitudinal central axis of the rigid device.
Selon un dix-neuvième mode de réalisation, les deux pattes sont disposées à proximité immédiate du bord longitudinal de la plaque qui est destiné à être situé à proximité de la base de la têtière quand la nervure est en butée contre l'élément transversal de l'armature de la têtière.  According to a nineteenth embodiment, the two tabs are arranged in the immediate vicinity of the longitudinal edge of the plate which is intended to be located near the base of the headrest when the rib is abutting against the transverse element of the plate. frame of the headrest.
Selon un vingtième mode de réalisation, les deux pattes sont deux règles plates . Selon un vingt-et-unième mode de réalisation, les deux pattes sont formées par le pliage de deux zones prédéfinies de la plaque, ce qui permet leur réalisation aisée. Chaque patte est ainsi disposée le long d' un bord transversal de la plaque . According to a twentieth embodiment, the two legs are two flat rules. According to a twenty-first embodiment, the two tabs are formed by the folding of two predefined areas of the plate, which allows their easy realization. Each tab is thus disposed along a transverse edge of the plate.
Selon un vingt-deuxième mode de réalisation, le dispositif rigide comprend deux pattes supplémentaires qui sont saillantes de la face de la plaque portant les pattes . Les deux pattes supplémentaires sont disposées de façon à s'étendre de chaque côté de la têtière, entre cette dernière et des éléments fixes de l'armature du brancard, quand la nervure est en butée contre l'élément transversal de l'armature de la têtière. Les deux pattes supplémentaires sont adaptées à recevoir la capote. Selon ce mode de réalisation il est possible de fixer la capote aux deux pattes supplémentaires du dispositif rigide.  According to a twenty-second embodiment, the rigid device comprises two additional tabs which project from the face of the plate carrying the tabs. The two additional tabs are arranged so as to extend on each side of the headrest, between the latter and fixed elements of the frame of the stretcher, when the rib is in abutment against the transverse element of the frame of the headrest. The two additional legs are adapted to receive the hood. According to this embodiment it is possible to attach the hood to the two additional legs of the rigid device.
Selon un vingt-troisième mode de réalisation, les deux pattes supplémentaires sont disposées symétriquement par rapport à un axe central longitudinal du dispositif rigide.  According to a twenty-third embodiment, the two additional tabs are arranged symmetrically with respect to a longitudinal central axis of the rigid device.
Selon un vingt-quatrième mode de réalisation, les deux pattes supplémentaires sont disposées de façon à être chacune dans le prolongement de la patte correspondante. Selon ce mode de réalisation il est possible de fixer de façon rotative deux tiges : à chaque patte supplémentaire est fixée de façon rotative une première extrémité d'une première tige ; la seconde extrémité de la première tige est montée de façon rotative à une première extrémité d' une seconde tige ; la seconde extrémité de la seconde tige est reliée de façon rotative à une baleine (de préférence, la baleine qui délimite un accès à l'espace situé entre la capote et le matelas). L'ensemble formé par les première et seconde tiges est un compas permettant de définir la position de déploiement maximal de la capote . Du fait de la configuration du dispositif rigide (l'orientation et la disposition des pattes, des pattes supplémentaires) et des baleines, le compas n'est soumis à aucune contrainte dans la direction transversale . Selon un vingt-cinquième mode de réalisation, les deux pattes supplémentaires sont deux règles plates . According to a twenty-fourth embodiment, the two additional tabs are arranged to be each in the extension of the corresponding tab. According to this embodiment it is possible to rotatably fix two rods: each additional tab is rotatably attached to a first end of a first rod; the second end of the first rod is rotatably mounted at a first end of a second rod; the second end of the second rod is rotatably connected to a whale (preferably the whale which defines an access to the space between the hood and the mattress). The assembly formed by the first and second rods is a compass for defining the maximum deployment position of the hood. Because of the configuration of the rigid device (the orientation and the arrangement of the legs, additional legs) and the whales, the compass is not subject to any constraint in the transverse direction. According to a twenty-fifth embodiment, the two additional tabs are two flat rules.
Selon un vingt-sixième mode de réalisation, les deux pattes supplémentaires sont formées par le pliage de deux zones prédéfinies de la plaque, ce qui permet leur réalisation aisée. Chaque patte supplémentaire est ainsi disposée le long d'un bord transversal de la plaque.  According to a twenty-sixth embodiment, the two additional tabs are formed by folding two predefined areas of the plate, which allows their easy realization. Each additional leg is thus disposed along a transverse edge of the plate.
Selon un vingt-septième mode de réalisation, la plaque comprend deux ouvertures de passage, chaque ouverture de passage étant adaptée à permettre le passage d'une sangle supérieure de maintien. En utilisant deux sangles supérieures de maintien, une pour chaque ouverture de passage, il est possible de maintenir en toute sécurité le patient au brancard pendant les transports, notamment dans le cas d'un transport par véhicule. Dans ce cas, pour chaque sangle supérieure de maintien, une première extrémité est fixée à l'armature de la têtière via l'ouverture de passage correspondante, et une deuxième extrémité est fixée de façon amovible à un harnais de maintien ou à tout autre dispositif similaire. Deux sangles inférieures de maintien peuvent également être fixées de façon amovible au harnais de maintien, chaque sangle inférieure de maintien étant par ailleurs fixée à l'armature du brancard.  According to a twenty-seventh embodiment, the plate comprises two passage openings, each passage opening being adapted to allow the passage of an upper retaining strap. By using two upper holding straps, one for each passage opening, it is possible to keep the patient safely stretcher during transport, especially in the case of transport by vehicle. In this case, for each upper holding strap, a first end is attached to the headrest frame via the corresponding through opening, and a second end is removably attached to a holding harness or other device. similar. Two lower holding straps can also be removably attached to the holding harness, each lower holding strap being further attached to the frame of the stretcher.
Selon un vingt-huitième mode de réalisation, les deux ouvertures de passage sont disposées symétriquement par rapport à un axe central longitudinal du dispositif rigide.  According to a twenty-eighth embodiment, the two passage openings are arranged symmetrically with respect to a longitudinal central axis of the rigid device.
Selon un vingt-neuvième mode de réalisation, la plaque comprend deux fentes principales de passage, chaque fente principale de passage étant adaptée à permettre le passage d'une ceinture de sécurité adaptée à ceinturer l'armature de la têtière et ainsi à serrer fermement le dispositif rigide (et la capote associée) au brancard. La ceinture de sécurité permet d'empêcher le déplacement involontaire du dispositif rigide (et la capote associée) hors du brancard, notamment pendant un transport du brancard dans un véhicule . Selon ce mode de réalisation, la ceinture de sécurité forme une boucle dont la partie supérieure est disposée le long de la surface supérieure de la plaque, et dont la partie inférieure est adaptée à être disposée sous l'armature de la têtière. De préférence, afin de permettre une liaison amovible entre les deux extrémités de la ceinture de sécurité, une première extrémité porte un premier moyen de liaison adapté à coopérer avec un second moyen de liaison porté par la deuxième extrémité . According to a twenty-ninth embodiment, the plate comprises two main passage slots, each main passage slot being adapted to allow the passage of a seat belt adapted to surround the armature of the headrest and thus to firmly tighten the rigid device (and the hood associated) to the stretcher. The seat belt prevents the involuntary movement of the rigid device (and the associated hood) out of the stretcher, in particular during a transport of the stretcher in a vehicle. According to this mode of embodiment, the safety belt forms a loop whose upper part is disposed along the upper surface of the plate, and whose lower part is adapted to be disposed under the frame of the headrest. Preferably, to allow a removable connection between the two ends of the safety belt, a first end carries a first connecting means adapted to cooperate with a second connecting means carried by the second end.
Selon un trentième mode de réalisation, les deux fentes principales de passage sont disposées symétriquement par rapport à un axe central longitudinal du dispositif rigide.  According to a thirtieth embodiment, the two main passage slots are arranged symmetrically with respect to a longitudinal central axis of the rigid device.
Selon un trente-et-unième mode de réalisation, les deux fentes principales de passage sont disposées à proximité immédiate du bord longitudinal de la plaque qui est destiné à être situé à proximité de la base de la têtière quand la nervure est en butée contre l'élément transversal de l'armature de la têtière .  According to a thirty-first embodiment, the two main passage slots are arranged in the immediate vicinity of the longitudinal edge of the plate which is intended to be located near the base of the headrest when the rib is in abutment against the transverse element of the frame of the headrest.
Selon un trente-deuxième mode de réalisation, les deux fentes principales de passage sont orientées parallèlement à l'axe longitudinal du dispositif rigide.  According to a thirty-second embodiment, the two main passage slots are oriented parallel to the longitudinal axis of the rigid device.
Selon un trente-troisième mode de réalisation, chaque fente principale de passage est disposée à environ 5 cm d'un bord transversal de la plaque.  According to a thirty-third embodiment, each main passage slot is disposed about 5 cm from a transverse edge of the plate.
Selon un trente-quatrième mode de réalisation, la plaque comprend deux fentes secondaires de passage adaptées à permettre le passage de la ceinture de sécurité, chaque fente secondaire de passage étant associée et disposée à proximité d'une fente principale de passage. Ce mode de réalisation permet une mise en place aisée du dispositif rigide (et de la capote associée) entre le matelas et l'armature de la têtière : la partie supérieure de la boucle formée par la ceinture de sécurité est divisée en trois parties : une partie centrale disposée entre deux parties latérales. Chaque partie latérale est délimitée par une fente principale de passage et par la fente secondaire de passage qui lui est associée, et la partie centrale est délimitée par les deux fentes secondaires de passage. Seules les deux parties latérales de la boucle supérieure de la ceinture de sécurité s'étendent le long de la surface supérieure de la plaque (et sont donc en contact avec le matelas lors de la mise en place du dispositif rigide équipé de la capote) . La partie centrale, s 'étendant sous la plaque (plus précisément, entre la plaque et une partie inférieure de la capote) , ne peut frotter contre le matelas . According to a thirty-fourth embodiment, the plate comprises two secondary passage slots adapted to allow the passage of the seat belt, each secondary passage slot being associated and disposed near a main passage slot. This embodiment allows an easy implementation of the rigid device (and the associated hood) between the mattress and the frame of the headrest: the upper part of the buckle formed by the safety belt is divided into three parts: a central portion disposed between two side portions. Each lateral part is delimited by a main passage slot and by the secondary slot of passage associated with it, and the central portion is delimited by the two secondary slots passage. Only the two lateral parts of the upper buckle of the safety belt extend along the upper surface of the plate (and are therefore in contact with the mattress during the introduction of the rigid device equipped with the hood). The central part, extending under the plate (more precisely, between the plate and a lower part of the hood), can not rub against the mattress.
Selon un trente-cinquième mode de réalisation, les deux fentes secondaires de passage sont disposées symétriquement par rapport à un axe central longitudinal du dispositif rigide.  According to a thirty-fifth embodiment, the two secondary passage slots are arranged symmetrically with respect to a longitudinal central axis of the rigid device.
Selon un trente-sixième mode de réalisation, les deux fentes secondaires de passage sont disposées à proximité immédiate du bord longitudinal de la plaque qui est destiné à être situé à proximité de la base de la têtière quand la nervure est en butée contre l'élément transversal de l'armature de la têtière.  According to a thirty-sixth embodiment, the two secondary passage slots are arranged in the immediate vicinity of the longitudinal edge of the plate which is intended to be located near the base of the headrest when the rib is in abutment against the element. transverse of the frame of the headrest.
Selon un trente-septième mode de réalisation, les deux fentes secondaires de passage sont orientées parallèlement aux deux fentes principales de passage.  According to a thirty-seventh embodiment, the two secondary passage slots are oriented parallel to the two main passage slots.
Selon un trente-huitième mode de réalisation, chaque fente secondaire de passage est disposée, selon la direction transversale, à environ 3 cm de la fente principale de passage qui lui est associée.  According to a thirty-eighth embodiment, each secondary passage slot is arranged, in the transverse direction, about 3 cm from the main passage slot associated therewith.
Selon un second aspect, l'invention concerne une capote adaptée à être reliée à dispositif rigide qui comprend une plaque et une nervure saillante de la plaque, la capote définissant une cavité interne ayant un unique accès, la capote comprenant, d'une part, une nappe inférieure plane et, d'autre part, une nappe supérieure en forme de capote de landau formant une surface de protection, chaque nappe comportant un rebord formé d'une première partie et d'une seconde partie complémentaire de la première partie, l'accès à la cavité interne étant délimité par les premières parties des rebords des nappes inférieure et supérieure de façon à permettre le glissement de la nappe inférieure entre une armature d'une têtière d'un brancard et un matelas reposant sur l'armature et à avoir la nappe supérieure disposée au-dessus de la têtière, caractérisé en ce que la nappe inférieure comprend une fente permettant le passage de la nervure du dispositif rigide quand la plaque de ce dispositif est disposée dans la cavité contre la nappe inférieure . According to a second aspect, the invention relates to a hood adapted to be connected to a rigid device which comprises a plate and a protruding rib of the plate, the hood defining an internal cavity having a single access, the hood comprising, on the one hand, a flat lower ply and, on the other hand, an upper ply in the shape of a pram cover forming a protective surface, each ply comprising a rim formed of a first part and a second part complementary to the first part, access to the internal cavity being delimited by the first portions of the flanges of the lower and upper plies so as to allow the sliding of the lower ply between a frame of a headrest of a stretcher and a mattress resting on the frame and to have the upper ply disposed above the headrest, characterized in that that the lower ply comprises a slot allowing the passage of the rib of the rigid device when the plate of this device is disposed in the cavity against the lower ply.
Ainsi, en utilisant une capote dont la forme de la nappe inférieure et la position de la fente correspondent à la forme de la plaque et la position de la nervure d'un dispositif rigide, il est possible de réaliser un maintien relativement serré de la capote au dispositif rigide .  Thus, by using a hood whose shape of the lower sheet and the position of the slot correspond to the shape of the plate and the position of the rib of a rigid device, it is possible to achieve a relatively tight hold of the hood to the rigid device.
Selon un premier mode de réalisation, les nappes inférieure et supérieure sont réalisées en tissu.  According to a first embodiment, the lower and upper plies are made of fabric.
Selon un second mode de réalisation, la nappe inférieure comprend un système de mise sous tension permettant une variation de la tension de la nappe inférieure. Ainsi, un tel système permet de diminuer la tension de la nappe inférieure afin de faciliter la mise en place du dispositif rigide, puis de renforcer la tension une fois le dispositif rigide en place.  According to a second embodiment, the lower sheet comprises a tensioning system allowing a variation of the tension of the lower sheet. Thus, such a system makes it possible to reduce the tension of the lower sheet in order to facilitate the installation of the rigid device, and then to reinforce the tension once the rigid device is in place.
Selon un troisième mode de réalisation, le système de mise sous tension est formé par une fermeture à glissière dont une extrémité débouche à la première partie du rebord de la nappe inférieure.  According to a third embodiment, the tensioning system is formed by a slide fastener, one end of which opens at the first part of the rim of the lower sheet.
Selon un quatrième mode de réalisation, la nappe supérieure est articulée autour d'un axe transversal de déploiement disposé le long de la première partie du rebord de la nappe inférieure, entre une position déployée dans laquelle la nappe supérieure recouvre sensiblement la nappe inférieure et une position repliée dans laquelle elle la découvre .  According to a fourth embodiment, the upper ply is articulated about a transverse axis of deployment disposed along the first portion of the rim of the lower ply, between an extended position in which the upper ply substantially covers the lower ply and a folded position in which she discovers it.
Selon un cinquième mode de réalisation, la nappe supérieure est formée de panneaux rigides reliés les uns aux autres au niveau de l'axe transversal de déploiement. Selon un sixième mode de réalisation, la nappe supérieure est tendue selon la direction transversale définie par l'axe transversal de déploiement par des baleines reliées les unes aux autres au niveau de l'axe transversal de déploiement. According to a fifth embodiment, the upper sheet is formed of rigid panels connected to each other at the transverse axis of deployment. According to a sixth embodiment, the upper sheet is stretched in the transverse direction defined by the transverse axis of deployment by whales connected to each other at the transverse axis of deployment.
Selon un septième mode de réalisation, la capote comprend, de chaque côté, un compas ayant deux tiges articulées l'une à l'autre, une première tige étant adaptée à être montée rotative au dispositif rigide et la seconde tige étant montée de façon rotative à la baleine qui délimite l'accès à la cavité interne de la capote.  According to a seventh embodiment, the hood comprises, on each side, a compass having two rods articulated to each other, a first rod being adapted to be rotatably mounted to the rigid device and the second rod being rotatably mounted. the whale which defines the access to the inner cavity of the hood.
Selon un huitième mode de réalisation, la nappe supérieure comprend une zone transparente . Cette zone permet notamment aux ambulanciers de pouvoir regarder la tête du patient .  According to an eighth embodiment, the upper layer comprises a transparent zone. This area allows paramedics to look at the patient's head.
Selon un neuvième mode de réalisation, la nappe inférieure comprend deux fentes de passage, chaque fente de passage étant adaptée à permettre le passage de la sangle supérieure de maintien mentionnée au vingt-septième mode de réalisation du premier aspect de l'invention.  According to a ninth embodiment, the lower ply comprises two passage slots, each passage slot being adapted to allow the passage of the upper holding strap mentioned in the twenty-seventh embodiment of the first aspect of the invention.
Selon un dixième mode de réalisation, les deux fentes de passage sont disposées de façon à être dans le prolongement vertical des deux ouvertures de passage mentionnées aux vingt- septième et vingt-huitième modes de réalisation du premier aspect de l'invention. De ce fait, les sangles supérieures de maintien ne génèrent pas de tension entre le dispositif rigide et la capote.  According to a tenth embodiment, the two passage slots are arranged to be in the vertical extension of the two passage openings mentioned in the twenty-seventh and twenty-eighth embodiments of the first aspect of the invention. As a result, the upper holding straps do not generate tension between the rigid device and the hood.
Selon un onzième mode de réalisation, la capote comprend, à sa face externe, deux ceintures adaptées à être reliées l'une à l'autre en ceinturant l'armature de la têtière et ainsi à serrer fermement la capote (et le dispositif rigide associé) au brancard. Les deux ceintures reliées l'une à l'autre permettent d'empêcher le déplacement involontaire de la capote (et du dispositif rigide associé) hors du brancard, notamment pendant un transport du brancard dans un véhicule . Selon un douzième mode de réalisation, afin de permettre une liaison amovible des deux ceintures, chaque ceinture porte à une première extrémité un moyen de liaison adapté à coopérer avec le moyen de liaison porté par l'autre ceinture. According to an eleventh embodiment, the hood comprises, on its outer face, two belts adapted to be connected to one another by surrounding the armature of the headrest and thus to firmly tighten the hood (and the associated rigid device ) to the stretcher. The two belts connected to each other to prevent the involuntary movement of the hood (and the associated rigid device) out of the stretcher, especially during transport of the stretcher in a vehicle. According to a twelfth embodiment, to allow a removable connection of the two belts, each belt carries at one end a connecting means adapted to cooperate with the connecting means carried by the other belt.
Selon un treizième mode de réalisation, les deux ceintures sont fixées à la capote au niveau de l'accès à la cavité interne .  According to a thirteenth embodiment, the two belts are fixed to the hood at the access to the internal cavity.
Selon un quatorzième mode de réalisation, les deux ceintures sont fixées à la capote au niveau de l'axe transversal de déploiement de la nappe supérieure .  According to a fourteenth embodiment, the two belts are fixed to the hood at the transverse axis of deployment of the upper web.
Selon un quinzième mode de réalisation, les deux ceintures sont cousues à la capote qui est en tissu.  According to a fifteenth embodiment, the two belts are sewn to the hood which is fabric.
Selon un seizième mode de réalisation, la nappe inférieure comprend deux fentes complémentaires de passage, chaque fente complémentaire de passage étant adaptée à permettre le passage de la ceinture de sécurité mentionnée du vingt-neuvième au trente-huitième mode de réalisation du premier aspect de 1' invention .  According to a sixteenth embodiment, the lower ply comprises two complementary passage slots, each complementary passage slot being adapted to allow the passage of the mentioned seat belt from the twenty-ninth to the thirty-eighth embodiment of the first aspect of 1 invention.
Selon un dix-septième mode de réalisation, les deux fentes complémentaires de passage sont disposées de façon à être dans le prolongement vertical des deux fentes principal de passage. De ce fait, la ceinture de sécurité ne génère pas de tension entre le dispositif rigide et la capote.  According to a seventeenth embodiment, the two complementary passage slots are arranged to be in the vertical extension of the two main passage slots. As a result, the seat belt does not generate tension between the rigid device and the hood.
Selon un troisième aspect, l'invention comprend un système de protection adapté à être associé à une têtière d' un brancard pour protéger une tête d'un patient, le système comprenant un dispositif rigide conforme au premier aspect de l'invention, et une capote conforme au second aspect .  According to a third aspect, the invention comprises a protection system adapted to be associated with a headrest of a stretcher for protecting a head of a patient, the system comprising a rigid device according to the first aspect of the invention, and a hood according to the second aspect.
Selon un mode de réalisation particulier, quand le dispositif rigide est conforme au vingt-neuvième mode de réalisation du premier aspect et la capote est conforme au seizième mode de réalisation, le système de protection comprend une ceinture de sécurité adaptée à ceinturer le système de protection au brancard. According to a particular embodiment, when the rigid device conforms to the twenty-ninth embodiment of the first aspect and the hood conforms to the sixteenth embodiment, the protection system comprises a seat belt adapted to surround the protection system on the stretcher.

Comme illustré à la figure 1, un brancard est associé d'un système de protection 1 conforme à la présente invention permettant de protéger une tête d'un patient. Le brancard s'étend selon une direction longitudinale 2 et il comprend une têtière 3 qui, ici, est articulée selon un axe d'articulation s 'étendant selon la direction transversale 4 de façon à pouvoir être relevée ou abaissée. As illustrated in Figure 1, a stretcher is associated with a protection system 1 according to the present invention to protect a head of a patient. The stretcher extends in a longitudinal direction 2 and comprises a headrest 3 which, here, is articulated along an axis of articulation extending in the transverse direction 4 so as to be raised or lowered.
La têtière 3 comprend, selon la direction longitudinale 2, une extrémité de base 5 parallèle et adjacente à l'axe d'articulation, et une extrémité libre opposée à l'extrémité de base 5. La têtière 3 comprend, d'une part, une armature 6 qui comporte des éléments longitudinaux et des éléments transversaux, et, d'autre part, un matelas 7 reposant sur l'armature 6. Dans les présents modes de réalisation, des moyens de déplacement de la têtière 3 (ici, un vérin) sont fixés à l'élément transversal de l'armature de la têtière 3 le plus proche de l'extrémité libre.  The headrest 3 comprises, in the longitudinal direction 2, a base end 5 parallel to and adjacent to the axis of articulation, and a free end opposite to the base end 5. The headrest 3 comprises, on the one hand, an armature 6 which comprises longitudinal elements and transverse elements, and, on the other hand, a mattress 7 resting on the armature 6. In the present embodiments, means for moving the headrest 3 (here, a jack ) are fixed to the transverse element of the armature of the headrest 3 closest to the free end.
Le brancard comprend également une armature fixe par rapport à laquelle la têtière 3 est articulée. L'armature fixe comprend des barres longitudinales 8 qui s'étendent tout le long du brancard et portent les poignées de manipulation de ce dernier . Au niveau de la zone longitudinale de la têtière 3, les deux barres longitudinales 8 sont disposées de façon adjacente à la têtière 3.  The stretcher also comprises a fixed armature with respect to which the headrest 3 is hinged. The fixed armature comprises longitudinal bars 8 which extend along the stretcher and carry the handling handles thereof. At the level of the longitudinal zone of the headrest 3, the two longitudinal bars 8 are arranged adjacent to the headrest 3.
Le système de protection 1 comprend un dispositif rigide 9 et une capote 10 reliée au dispositif rigide 9. Le système de protection 1 est configurée de façon à permettre, d'une part, le glissement, selon la direction longitudinale 2 du brancard, du dispositif rigide 9 entre l'armature 6 et le matelas 7 de la têtière 3, et, d'autre part, la fixation de la capote 10 au dispositif rigide 9 en faisant passer une partie de la capote 10 et une partie du dispositif rigide 9 de chaque côté de la têtière 3, entre celle-ci et la barre longitudinale 8 correspondante .  The protection system 1 comprises a rigid device 9 and a hood 10 connected to the rigid device 9. The protection system 1 is configured so as to allow, on the one hand, the sliding, in the longitudinal direction 2 of the stretcher, of the device. rigid 9 between the frame 6 and the mattress 7 of the headrest 3, and, secondly, the attachment of the hood 10 to the rigid device 9 by passing a portion of the hood 10 and a portion of the rigid device 9 of each side of the headrest 3, between the latter and the corresponding longitudinal bar 8.
Dans le premier mode de réalisation, le dispositif rigide 9 (ici, en métal) est adapté à porter la capote 10, et ici à y être fixé. Dans le second mode de réalisation, le dispositif rigide (ici, en matière plastique) est monobloc avec une partie de la capote 10. In the first embodiment, the rigid device 9 (here metal) is adapted to wear the hood 10, and here to be fixed. In the second embodiment, the device rigid (here, plastic) is monobloc with a portion of the hood 10.
Le dispositif rigide 9 comprend une plaque 24 qui est destinée à être disposée entre l'armature 6 et le matelas 7 de la têtière 3.  The rigid device 9 comprises a plate 24 which is intended to be disposed between the armature 6 and the mattress 7 of the headrest 3.
La capote 10, quand elle est tendue, définit une cavité interne avec un unique accès 11. La cavité interne est délimitée par deux nappes 12, 13 : une nappe inférieure plane 12 et une nappe supérieure 13 en forme de capote de landau, la nappe supérieure 13 étant une surface de protection permettant de protéger la tête du patient . La nappe inférieure 12 comporte un rebord qui comprend une première partie 14 et une seconde partie 15, la nappe supérieure 13 comportant également un rebord qui comprend une première partie 16 et une seconde partie 17. Les secondes parties 15, 17 des rebords des nappes inférieure 12 et supérieure 13 sont reliées entre elles. L'accès 11 à la cavité interne est délimité par les premières parties 14, 16 des rebords des nappes inférieure 12 et supérieure 13.  The hood 10, when stretched, defines an internal cavity with a single access 11. The internal cavity is delimited by two plies 12, 13: a flat lower ply 12 and an upper ply 13 in the shape of a pram cover, the ply upper 13 being a protective surface for protecting the patient's head. The lower ply 12 has a flange which includes a first portion 14 and a second portion 15, the upper ply 13 also having a flange which includes a first portion 16 and a second portion 17. The second portions 15, 17 of the flanges of the lower plies 12 and 13 are interconnected. The access 11 to the internal cavity is delimited by the first portions 14, 16 of the edges of the lower and upper layers 12 and 13.
Quand le dispositif rigide 9 est distinct de la capote 10 (comme dans le premier mode de réalisation) , il est destiné à être disposé dans la cavité interne, contre la nappe inférieure 12. Comme illustré à la figure 7, l'ensemble formé par la nappe inférieure 12 et le dispositif rigide 9 est destiné à être glissé entre l'armature 6 et le matelas 7 de la têtière 3 (la nappe supérieure 13 étant alors disposée au-dessus de la têtière 3) . La plaque 24 et la nappe inférieure 12 sont configurées de sorte que, mises en place, la plaque 24 tend la nappe inférieure 12.  When the rigid device 9 is distinct from the hood 10 (as in the first embodiment), it is intended to be disposed in the internal cavity, against the lower ply 12. As illustrated in FIG. 7, the assembly formed by the lower ply 12 and the rigid device 9 is intended to be slid between the frame 6 and the mattress 7 of the headrest 3 (the upper ply 13 is then disposed above the headrest 3). The plate 24 and the lower ply 12 are configured so that, put in place, the plate 24 tends to the lower ply 12.
Quand le dispositif rigide 9 est distinct de la capote 10, afin de faciliter la mise en place de la plaque 24 contre la nappe inférieure 12 , cette dernière comprend un système de mise sous tension 18 permettant de faire varier la tension de la nappe inférieure 12 (ici, le système de mise sous tension 18 est formé par une fermeture à glissière 18 débouchant à la première partie 14 du rebord de la nappe inférieure 12) . Ainsi, il est possible de diminuer la tension de la nappe inférieure 12 (en ouvrant la fermeture à glissière 18) pour faciliter la mise en place du dispositif rigide 9, puis de renforcer la tension (en refermant la fermeture à glissière 18) une fois le dispositif rigide 9 en place . When the rigid device 9 is separate from the hood 10, to facilitate the establishment of the plate 24 against the lower ply 12, the latter comprises a power system 18 for varying the tension of the lower ply 12 (here, the power-up system 18 is formed by a zipper 18 opening at the first part 14 of the rim of the lower layer 12). Thus, it is possible to reduce the tension of the lower ply 12 (by opening the zipper 18) to facilitate the introduction of the rigid device 9, then to reinforce the tension (by closing the zipper 18) once the rigid device 9 in place.
La nappe supérieure 13 est articulée autour d'un axe de déploiement qui est disposé le long de la première partie 14 du rebord de la nappe inférieure 12 (au niveau de la têtière 3) . La nappe supérieure 13 peut varier entre un état déployé dans lequel elle recouvre sensiblement l'ensemble formé par la nappe inférieure 12, la plaque 24 et la têtière 3, et un état replié dans laquelle elle découvre cet ensemble.  The upper ply 13 is hinged about a deployment axis which is arranged along the first portion 14 of the rim of the lower ply 12 (at the level of the headrest 3). The upper ply 13 may vary between an expanded state in which it substantially covers the assembly formed by the lower ply 12, the plate 24 and the headrest 3, and a folded state in which it discovers this assembly.
Le dispositif rigide 9 comprend également une nervure 19 qui est saillante de la plaque 24 et qui est adaptée à venir en butée contre un élément transversal de l'armature 6 quand le dispositif rigide 9 est glissé selon une direction parallèle à la direction longitudinale 2 du brancard. Ici, la nervure 19 est une règle plate et a été formée par le pliage d'une zone 20 partiellement prédécoupée d'une pièce 21 brute correspondant sensiblement au dispositif rigide 9. Cette nervure 19 s'étend perpendiculairement à la plaque 24 et selon la direction transversale 4. La mise en butée de la nervure 19 permet de définir la position d'utilisation du système de protection 1. La nervure 19 porte, à son extrémité libre, une nervure supplémentaire 22 qui définit, avec la nervure 19 et la plaque 24, un logement 23 pour l'élément transversal de l'armature 6 de la têtière 3 contre lequel la nervure 19 vient en butée. Ici, la nervure supplémentaire 22 est une règle plate et a été formée par pliage, comme la nervure 19, d'une seconde zone 25 prédécoupée de la pièce 21. La nervure supplémentaire 22 est le prolongement de la nervure 19. Cette nervure supplémentaire 22 s'étend perpendiculairement à la nervure 19 (parallèlement à la plaque 24) . Quand le dispositif rigide 9 est glissé entre le matelas 7 et l'armature 6 de la têtière 3 jusqu'à ce que la nervure 19 soit en butée contre l'élément transversal de l'armature 6, cet élément transversal est disposé dans le logement 23. De ce fait le système de protection 1 est ancré à la têtière 3 et ne peut pas basculer seul (par exemple, en cas de vent violent), ni heurter le patient. De plus, la nervure 19 et la nervure supplémentaire 22 sont configurées de façon à ne pas gêner le fonctionnement des moyens de déplacement de la têtière 3. The rigid device 9 also comprises a rib 19 which protrudes from the plate 24 and which is adapted to abut against a transverse element of the armature 6 when the rigid device 9 is slid in a direction parallel to the longitudinal direction 2 of the stretcher. Here, the rib 19 is a flat rule and was formed by folding a partially precut zone 20 of a raw part 21 substantially corresponding to the rigid device 9. This rib 19 extends perpendicular to the plate 24 and according to the transverse direction 4. The abutment of the rib 19 defines the position of use of the protection system 1. The rib 19 carries, at its free end, an additional rib 22 which defines, with the rib 19 and the plate 24, a housing 23 for the transverse element of the frame 6 of the headrest 3 against which the rib 19 abuts. Here, the additional rib 22 is a flat ruler and has been formed by folding, like the rib 19, a second precut zone 25 of the piece 21. The additional rib 22 is an extension of the rib 19. This additional rib 22 extends perpendicular to the rib 19 (parallel to the plate 24). When the rigid device 9 is slid between the mattress 7 and the armature 6 of the headrest 3 until the rib 19 is in abutment against the transverse element of the armature 6, this transverse element is disposed in the housing 23. As a result, the protection system 1 is anchored to the headrest 3 and can not rock alone (for example, in case of strong wind), do not hit the patient. In addition, the rib 19 and the additional rib 22 are configured so as not to hinder the operation of the means for moving the headrest 3.
Quand le dispositif rigide 9 est distinct de la capote 10, la nappe inférieure 12 comprend une fente 26 permettant le passage de la nervure 19 et de la nervure supplémentaire 22. Si nécessaire, afin de faciliter ce passage, le système de mise sous tension 18 atteint cette fente 26 et/ou un second système de mise sous tension (par exemple une fermeture à glissière) est disposé de façon à déboucher dans la fente 26.  When the rigid device 9 is distinct from the hood 10, the lower sheet 12 comprises a slot 26 allowing the passage of the rib 19 and the additional rib 22. If necessary, to facilitate this passage, the power system 18 reached this slot 26 and / or a second energizing system (for example a zipper) is arranged to open into the slot 26.
Si nécessaire, afin de réaliser une fixation avec le brancard, la nervure 19 et/ou la nervure supplémentaire 22 et/ou la plaque 24 peuvent comprendre, chacun, au moins un orifice 27, 28, 29 permettant, quand le dispositif rigide 1 est correctement mis en place, une fixation par le passage d'un élément de fixation (tel qu'une vis) coopérant avec un élément structurel de la têtière 3.  If necessary, in order to achieve a fixation with the stretcher, the rib 19 and / or the additional rib 22 and / or the plate 24 may each comprise at least one orifice 27, 28, 29 allowing, when the rigid device 1 is correctly set up, a fixing by the passage of a fastening element (such as a screw) cooperating with a structural element of the headrest 3.
Dans les présents modes de réalisation, la plaque 24 a la forme d' un rectangle prolongé sur un côté transversal par un demi-disque dont le diamètre est égal à la longueur des côtés transversaux. Le rectangle est destiné à être disposé du côté de l'extrémité de base 5 de la têtière 3, et le demi-disque du côté de l'extrémité libre de celle-ci. Quand le dispositif rigide 9 est distinct de la capote 10, la forme de la nappe inférieure 12 correspond à celle de la plaque 24. Plus la forme de la plaque 24 (et, le cas échéant, de la nappe inférieure 12) est proche d'un rectangle, plus le système de protection peut être utilisé avec des brancards ayant une têtière dont l'extrémité libre est large . Selon les premier et troisième modes de réalisation illustrés aux figures 1, 5 et 6, les nappes inférieure 12 et supérieure 13 sont réalisées en tissu. Ici, afin de permettre aux ambulanciers de surveiller le patient, la nappe supérieure 13 comprend une zone transparente 30. La nappe supérieure 13 est tendue selon la direction transversale par des baleines 31 qui sont reliées les unes aux autres par leurs deux extrémités au niveau de l'axe de déploiement. Afin de tendre la nappe supérieure 13 selon la direction longitudinale 2 quand elle est dans son état déployé, la capote 10 comprend, de chaque côté, un compas 32 comprenant deux tiges 33, 34 articulées l'une à l'autre. L'une 33 des tiges est montée en rotation par ses deux extrémités, d'une part à la baleine 31 qui délimite l'accès 11 à la cavité interne et qui forme la première partie 16 du rebord de la nappe supérieure 13, et, d'autre part, à une première extrémité de l'autre tige 34. In the present embodiments, the plate 24 has the shape of a rectangle extended on a transverse side by a half-disk whose diameter is equal to the length of the transverse sides. The rectangle is intended to be disposed on the side of the base end 5 of the headrest 3, and the half-disc on the side of the free end thereof. When the rigid device 9 is distinct from the hood 10, the shape of the lower ply 12 corresponds to that of the plate 24. The shape of the plate 24 (and, where appropriate, the lower ply 12) is close to a rectangle, plus the protection system can be used with stretchers having a headrest whose free end is wide. According to the first and third embodiments illustrated in FIGS. 1, 5 and 6, the lower plies 12 and upper 13 are made of fabric. Here, in order to allow the paramedics to monitor the patient, the upper sheet 13 comprises a transparent zone 30. The upper sheet 13 is stretched in the transverse direction by whales 31 which are connected to each other by their two ends at the level of the deployment axis. In order to tension the upper sheet 13 in the longitudinal direction 2 when it is in its deployed state, the hood 10 comprises, on each side, a compass 32 comprising two rods 33, 34 articulated to one another. One of the rods is rotated by its two ends, on the one hand to the whale 31 which delimits the access 11 to the internal cavity and which forms the first part 16 of the rim of the upper ply 13, and on the other hand, at one end of the other rod 34.
Selon les premier et troisième modes de réalisation, le dispositif rigide 9 comprend, de chaque côté longitudinal de la plaque 24, une patte 40 et une patte supplémentaire 41 qui sont saillantes de la face supérieure de la plaque 24 opposée à celle (inférieure) portant la nervure 19. Les deux pattes 40 et les deux pattes supplémentaires 41 permettent de réaliser une fixation de la capote 10 au dispositif rigide 9. Elles sont formées par quatre règles plates qui sont disposées de façon à s'étendre de chaque côté de la têtière 3, entre cette dernière et les barres longitudinales 8 du brancard, quand le système de protection 1 est en place sur ce dernier. De préférence, les deux pattes 40 et les deux pattes supplémentaires 41 font saillie verticalement au-delà du matelas 7 de façon à faciliter la fixation de la capote 10. Elles sont formées par le pliage de quatre zones prédéfinies de la plaque 35, 36.  According to the first and third embodiments, the rigid device 9 comprises, on each longitudinal side of the plate 24, a lug 40 and an additional lug 41 which project from the upper face of the plate 24 opposite to that (lower) bearing the rib 19. The two tabs 40 and the two additional tabs 41 allow a fastening of the hood 10 to the rigid device 9. They are formed by four flat rules which are arranged to extend on each side of the headrest 3, between the latter and the longitudinal bars 8 of the stretcher, when the protection system 1 is in place on the latter. Preferably, the two tabs 40 and the two additional tabs 41 protrude vertically beyond the mattress 7 so as to facilitate the attachment of the hood 10. They are formed by the folding of four predefined zones of the plate 35, 36.
Les deux pattes 40 et les deux pattes supplémentaires 41 sont disposées symétriquement par rapport à 1 ' axe longitudinal du dispositif rigide 9. Les deux pattes 40 sont disposées à proximité immédiate du bord de la plaque 24, de façon adjacente à l'accès 11 à la cavité interne de la capote 10. Il est possible de fixer à chaque patte 40 une charnière définissant l'axe de déploiement de la nappe supérieure 13. Ici, la fixation se fait par rivetage des extrémités des baleines 31 montées en rotation autour du rivet . The two tabs 40 and the two additional tabs 41 are arranged symmetrically with respect to the longitudinal axis of the rigid device 9. The two tabs 40 are arranged in the immediate vicinity of the edge of the plate 24, adjacent to the access 11 to the internal cavity of the hood 10. It is possible to fix each leg 40 a hinge defining the axis of deployment of the upper ply 13. Here, the attachment is by riveting the ends of the whales 31 rotatably mounted around the rivet.
Chaque patte supplémentaire 41 est disposée de façon à être dans le prolongement de la patte 40 correspondante. Il est possible de fixer de façon rotative, à chaque patte supplémentaire 41, la deuxième extrémité de l'autre tige 34 du compas 32 correspondant. De préférence, chaque patte supplémentaire 41 est disposée le plus loin possible de la patte correspondante 40. Du fait de la configuration du dispositif rigide 9 et de la capote 10, les compas 32 ne sont soumis à aucune contrainte autre que les contraintes longitudinales. Ici, la fixation de la nappe supérieure 13 et de l'autre tige 34 du compas 32 à la plaque supplémentaire 41 se fait par rivetage, l'autre tige 34 du compas 32 étant montée en rotation autour du rivet .  Each additional tab 41 is arranged to be in line with the corresponding lug 40. It is possible to attach rotatably to each additional leg 41, the second end of the other rod 34 of the compass 32 corresponding. Preferably, each additional tab 41 is disposed as far as possible from the corresponding tab 40. Due to the configuration of the rigid device 9 and the hood 10, the compasses 32 are not subjected to any stress other than the longitudinal stresses. Here, the attachment of the upper ply 13 and the other rod 34 of the compass 32 to the additional plate 41 is made by riveting, the other rod 34 of the compass 32 being rotatably mounted around the rivet.
Dans le premier mode de réalisation, le système de protection est mis en place par son simple coulissement longitudinal, la nappe inférieure 12 et le dispositif rigide 9 glissant entre le matelas 7 et l'armature 6 de la têtière 3.  In the first embodiment, the protection system is implemented by its simple longitudinal sliding, the lower sheet 12 and the rigid device 9 sliding between the mattress 7 and the frame 6 of the headrest 3.
Selon le second mode de réalisation, la surface de protection de la capote 10 est réalisée par quatre panneaux rigides articulés autour de l'axe de déploiement, la nappe inférieure et le dispositif rigide étant formé par un seul élément auquel les panneaux rigides de la capote 10 sont articulés autour de l'axe de déploiement.  According to the second embodiment, the protective surface of the hood 10 is formed by four rigid panels articulated around the deployment axis, the lower sheet and the rigid device being formed by a single element to which the rigid panels of the hood 10 are articulated around the axis of deployment.
Comme illustré à la figure 5, dans le troisième mode de réalisation, le système de protection 1 est configuré de façon à permettre le maintien en toute sécurité du patient au brancard pendant les transports, notamment dans le cas d'un transport par véhicule. Classiquement, le maintien du patient est réalisé par un harnais auquel sont fixées de façon amovible quatre sangles de maintien : deux sangles supérieures (une du côté droit, l'autre du côté gauche) et deux sangles inférieures (une du côté 5 droit, l'autre du côté gauche). Les quatre sangles de maintien sont par ailleurs fixées (de préférence de façon amovible) , à l'armature du brancard. As illustrated in FIG. 5, in the third embodiment, the protection system 1 is configured so as to allow the patient to be safely held in the stretcher during transport, in particular in the case of transport by vehicle. Conventionally, the patient is held by a harness to which four holding straps are removably attached: two upper straps (one on the right side, the other on the left side) and two lower straps (one on the right side, the other one on the right). other on the left). The four support straps are also fixed (preferably removably) to the frame of the stretcher.
De façon plus précise, les deux sangles supérieures de maintien sont fixées à l'armature 6 de la têtière 3. Afin de More specifically, the two upper support straps are attached to the frame 6 of the headrest 3. In order to
10 permettre le passage des deux sangles supérieures de maintien, d'une part, la plaque 24 comprend deux ouvertures de passage 42 (ici, les deux ouvertures de passage 42 sont disposées symétriquement par rapport à l'axe longitudinal du dispositif rigide 9), et, d'autre part, la nappe inférieure 12 de la capote10 allow the passage of the two upper holding straps, on the one hand, the plate 24 comprises two through openings 42 (here, the two passage openings 42 are arranged symmetrically with respect to the longitudinal axis of the rigid device 9), and, on the other hand, the lower ply 12 of the hood
15 10 comprend deux fentes de passage 43 (ici, les deux fentes de passage 43 sont disposées de façon à être dans le prolongement des deux ouvertures de passage 42) . 10 comprises two passage slots 43 (here, the two passage slots 43 are arranged to be in line with the two passage openings 42).
Comme illustré à la figure 6, dans le troisième mode de réalisation, le système de protection 1 est configuré de façon à 20 permettre son serrage ferme au brancard, ce serrage empêchant le déplacement du système de protection 1 hors du brancard par un mouvement inopiné de translation de retrait . Un tel mouvement peut notamment avoir lieu pendant les transports, notamment dans le cas d' un transport par véhicule .  As illustrated in FIG. 6, in the third embodiment, the protection system 1 is configured so as to allow it to be securely clamped to the stretcher, this clamping preventing the movement of the protection system 1 from the stretcher by an unexpected movement of withdrawal translation. Such a movement may especially take place during transport, especially in the case of transport by vehicle.
25 De façon plus précise, la capote 10 comprend, à sa face externe, deux ceintures 44 adaptées à être reliées l'une à l'autre en ceinturant, par le bas, la têtière 3 (plus précisément, en ceinturant l'armature 6 et le matelas 7 de la têtière 3) . Ici, les deux ceintures 44 sont fixées (ici, More specifically, the hood 10 comprises, on its outer face, two belts 44 adapted to be connected to one another by encircling, from below, the headrest 3 (more precisely, by surrounding the armature 6 and the mattress 7 of the headrest 3). Here, the two belts 44 are fixed (here,
30 cousues) au niveau de l'accès 11 à la cavité interne de la capote 10 (au niveau de l'axe de déploiement de la nappe supérieure 13) . Afin de permettre une liaison amovible entre elles, l'une des deux ceintures 44 porte un moyen de liaison 45 (ici, un moyen de liaison femelle) adapté à coopérer avec un30 sewn) at the access 11 to the internal cavity of the hood 10 (at the axis of deployment of the upper web 13). In order to allow a removable connection between them, one of the two belts 44 carries a connecting means 45 (here, a female connection means) adapted to cooperate with a
35 moyen de liaison 46 (ici, un moyen de liaison femelle) . Afin de pouvoir ajuster la position des moyens de liaison 45, 46 aux deux ceintures 44, chaque moyen de liaison 45, 46 est conformé de façon à permettre un passage répété de la ceinture 44 permettant un frottement de la ceinture avec elle-même . 35 connecting means 46 (here, a female connection means). In order to ability to adjust the position of the connecting means 45, 46 to the two belts 44, each connecting means 45, 46 is shaped to allow a repeated passage of the belt 44 allowing friction of the belt with itself.
Comme illustré à la figure 7, le quatrième mode de réalisation est une alternative au troisième mode de réalisation illustré à la figure 6 pour réaliser le serrage ferme du système de protection 1 au brancard.  As illustrated in FIG. 7, the fourth embodiment is an alternative to the third embodiment illustrated in FIG. 6 in order to firmly tighten the protection system 1 to the stretcher.
De façon plus précise, dans ce mode de réalisation, le système de protection 1 comprend une ceinture de sécurité 50 qui est associée au dispositif rigide 9 (plus précisément à la plaque 24 de ce dernier) et à la capote 10 (plus précisément à la nappe inférieure 12 de cette dernière) . Cette ceinture de sécurité 50 permet d'empêcher le déplacement involontaire du dispositif rigide 9 et la capote 10 hors du brancard, notamment pendant un transport du brancard dans un véhicule . Afin de permettre une liaison amovible entre les deux extrémités de la ceinture de sécurité 50, une première extrémité porte un premier moyen de liaison qui est adapté à coopérer avec un second moyen de liaison porté par la deuxième extrémité. De préférence, les moyens de liaison de ce présent mode de réalisation sont identiques à ceux du troisième mode de réalisation.  More specifically, in this embodiment, the protection system 1 comprises a safety belt 50 which is associated with the rigid device 9 (more precisely with the plate 24 of the latter) and with the hood 10 (more specifically with the lower sheet 12 of the latter). This safety belt 50 makes it possible to prevent the involuntary displacement of the rigid device 9 and the hood 10 from the stretcher, in particular during a transport of the stretcher in a vehicle. In order to allow a removable connection between the two ends of the safety belt 50, a first end carries a first connecting means which is adapted to cooperate with a second connecting means carried by the second end. Preferably, the connecting means of this present embodiment are identical to those of the third embodiment.
La ceinture de sécurité 50 forme une boucle dont la partie supérieure 51 est disposée au-dessus de la nappe inférieure 12 et dont la partie inférieure 52 est adaptée à être disposée sous l'armature 6 de la têtière.  The safety belt 50 forms a loop, the upper portion 51 is disposed above the lower ply 12 and the lower portion 52 is adapted to be disposed under the frame 6 of the headrest.
La nappe inférieure 12 comprend deux fentes complémentaires de passage 53 permettant le passage de la ceinture de sécurité 50 et faisant office de limite entre la partie supérieure 51 et la partie inférieure 52. La plaque 24 comprend deux fentes principales de passage 54 permettant le passage de la ceinture de sécurité 50. Les deux fentes principales de passage 54 sont disposées de façon à être dans le prolongement vertical des deux fentes complémentaires de passage 53 afin que la ceinture ne génère pas de tension sur la capote 10. De préférence, les deux fentes principales de passage 54 et les deux fentes complémentaires de passage 53 sont disposées symétriquement par rapport à un axe central longitudinal du système de protection 1. The lower sheet 12 comprises two complementary passage slots 53 allowing the passage of the seat belt 50 and serving as a boundary between the upper portion 51 and the lower portion 52. The plate 24 comprises two main passage slots 54 allowing the passage of the seat belt 50. The two main passage slots 54 are arranged to be in the vertical extension of the two complementary passage slots 53 so that the belt does not generate tension on the hood 10. Preferably, the two main passage slots 54 and the two complementary passage slots 53 are arranged symmetrically with respect to a longitudinal central axis of the protection system 1.
Afin de permettre un serrage efficace du système de protection 1 à la têtière 3, les deux fentes principales de passage 54 sont disposées à proximité immédiate du bord longitudinal de la plaque 24 qui est destiné à être situé à proximité de la base de la têtière 3.  In order to allow effective tightening of the protection system 1 to the headrest 3, the two main passage slots 54 are arranged in close proximity to the longitudinal edge of the plate 24 which is intended to be located near the base of the headrest 3 .
Afin que la ceinture de sécurité 50 ait une importante surface de serrage, les deux fentes principales de passage 54 et les deux fentes complémentaires de passage 53 sont orientées parallèlement à l'axe longitudinal du système de protection 1.  So that the safety belt 50 has a large clamping surface, the two main passage slots 54 and the two complementary passage slots 53 are oriented parallel to the longitudinal axis of the protection system 1.
Afin d'avoir un serrage efficace, même pour les brancards de largeur relativement faible, chaque fente principale de passage 54 est disposée à environ 5 cm d'un bord transversal de la plaque 24. De ce fait, il est beaucoup plus probable que la partie inférieure 52 de la ceinture de sécurité 50 soit serrée aux faces latérales des armatures 6 de la têtière 3, mêmes si les armatures 6 sont proches l'une de l'autre.  In order to have effective tightening, even for relatively small width stretchers, each main passage slot 54 is disposed about 5 cm from a transverse edge of the plate 24. As a result, it is much more likely that the lower part 52 of the safety belt 50 is clamped to the side faces of the frames 6 of the headrest 3, even if the frames 6 are close to each other.
Afin de ne pas être gêné lors de la mise en place du système de protection 1 entre le matelas 7 et l'armature 6 par une éventuelle mise en butée de la partie supérieure 51 de la ceinture de sécurité 50 contre le matelas 6, la plaque 24 comprend également deux fentes secondaires de passage 55 permettant le passage de la ceinture de sécurité 50 (plus précisément, le passage de la partie supérieure 51 de la ceinture de sécurité 50) . Chaque fente secondaire de passage 55 est associée et disposée à proximité d'une fente principale de passage 54. De ce fait, la partie supérieure 51 de la ceinture de sécurité 50 comprend une partie centrale 56 et deux parties latérales 57 disposées de part et d'autre de la partie centrale 56. Chaque partie latérale 57 est délimitée par une fente principale de passage 54 et par la fente secondaire de passage 55 qui lui est associée. La partie centrale 56 est délimitée par les deux fentes secondaires de passage 55. De ce fait, les deux parties latérales 57 sont situées au-dessus de la plaque 24 et la partie centrale 56 est située en-dessous (entre la plaque 24 et la nappe inférieure 12 de la capote 10) . En conséquence, seules les parties latérales 57 ont des risques de venir en butée contre le matelas 7. La longueur de chaque partie latérale 57 étant de préférence très faible (les fentes principale 54 et secondaire 55 de passage étant de préférence séparées de quelques centimètre - par exemple 3 cm) , le risque de décollage (même partiel) de la partie latérale 57 de la plaque 24 est quasi-nulle, ce qui entraîne un risque tout aussi faible de sa mise en butée contre le matelas 7. In order not to be embarrassed during the introduction of the protection system 1 between the mattress 7 and the armature 6 by a possible abutment of the upper portion 51 of the safety belt 50 against the mattress 6, the plate 24 also includes two secondary passage slots 55 for the passage of the safety belt 50 (more precisely, the passage of the upper portion 51 of the safety belt 50). Each secondary passage slot 55 is associated and disposed close to a main passage slot 54. As a result, the upper portion 51 of the seat belt 50 comprises a central portion 56 and two lateral portions 57 disposed on both sides. other of the central portion 56. Each lateral portion 57 is delimited by a slot main passage 54 and the secondary passage slot 55 associated therewith. The central portion 56 is delimited by the two secondary passage slots 55. As a result, the two lateral portions 57 are situated above the plate 24 and the central portion 56 is situated below (between the plate 24 and the lower sheet 12 of the hood 10). Consequently, only the lateral parts 57 have the risk of coming into abutment against the mattress 7. The length of each lateral portion 57 is preferably very small (the primary 54 and secondary 55 passage slots being preferably separated by a few centimeters - for example 3 cm), the risk of take-off (even partial) of the lateral part 57 of the plate 24 is almost zero, which entails an equally low risk of its abutment against the mattress 7.
De préférence, les deux fentes secondaires de passage 55 sont disposées symétriquement par rapport à un axe central longitudinal du système de protection 1.  Preferably, the two secondary passage slots 55 are arranged symmetrically with respect to a longitudinal central axis of the protection system 1.
Afin de ne pas contraindre la ceinture de sécurité, les deux fentes secondaires de passage 55 sont orientées parallèlement aux deux fentes principales de passage 54 et elles sont disposées à proximité immédiate du bord longitudinal de la plaque 24 qui est destiné à être situé à proximité de la base de la têtière 3.  In order not to constrain the safety belt, the two secondary passage slots 55 are oriented parallel to the two main passage slots 54 and they are arranged in the immediate vicinity of the longitudinal edge of the plate 24 which is intended to be located close to the base of the headrest 3.
Par ailleurs, d'une façon générale, les différents éléments constitutifs du système de protection sont conformés de façon à ne pas être dangereux, ni pour le patient, ni pour l'ambulancier, notamment les angles du dispositif rigide 9 qui sont tous arrondis .  Furthermore, in general, the various components of the protection system are shaped so as not to be dangerous, neither for the patient nor for the ambulance attendant, in particular the angles of the rigid device 9 which are all rounded.
