Description
PROCÉDÉ ET DISPOSITIF DE POSITIONNEMENT D’UNE BOUCLE DE CEINTURE DE SÉCURITÉ VIA UN PASSAGE D’UN SIÈGE DE VÉHICULE METHOD AND DEVICE FOR POSITIONING A SEAT BELT BUCKLE VIA A PASSAGE OF A VEHICLE SEAT
L’invention concerne les ceintures de sécurité qui sont associées à des sièges de véhicules, éventuellement de type automobile, et plus précisément le positionnement de la boucle de verrouillage de telles ceintures de sécurité. The invention relates to seat belts which are associated with vehicle seats, possibly of the automotive type, and more precisely the positioning of the locking buckle of such seat belts.
Certains véhicules, généralement de type automobile, comprennent au moins un siège (éventuellement une banquette) auquel doit être associée au moins une ceinture de sécurité dont la boucle de verrouillage est solidarisée à un lien (ou brin) passant entre son assise et son dossier. Ce lien (ou brin) comprend en effet une première extrémité qui est solidarisée fixement à un élément du véhicule, comme par exemple son plancher, avant l’installation du siège, et qui se retrouve donc initialement placé, avec la boucle (de verrouillage) associée, derrière la face arrière de ce siège ou sous ce dernier. Certain vehicles, generally of the automobile type, comprise at least one seat (possibly a bench seat) to which must be associated at least one seat belt, the locking loop of which is secured to a link (or strand) passing between its seat and its backrest. This link (or strand) indeed comprises a first end which is fixedly secured to an element of the vehicle, such as its floor, before the installation of the seat, and which is therefore found initially placed, with the loop (locking) associated behind the rear face of this seat or under it.
Une fois le siège installé sur le plancher du véhicule, il faut donc faire passer la boucle et une partie de son lien dans un passage très étroit défini entre l’assise et le dossier. L’étroitesse de ce passage, provoquée par les mousses de l’assise et du dossier contraint le technicien, qui doit installer la boucle, à pousser fortement d’une main cette dernière du côté de la face arrière du siège tout en écartant les mousses de l’autre main, ce qui s’avère non seulement contraignant physiquement, mais également très peu ergonomique et chronophage. En outre, cette opération manuelle peut parfois provoquer un endommagement local du revêtement de l’assise et/ou du dossier au voisinage du passage et/ou des plis qui nui(sen)t à l’impression de qualité. Once the seat is installed on the vehicle floor, it is therefore necessary to pass the buckle and part of its link in a very narrow passage defined between the seat and the backrest. The narrowness of this passage, caused by the foam of the seat and the backrest, forces the technician, who must install the buckle, to strongly push it with one hand on the side of the rear face of the seat while spreading the foam. with the other hand, which is not only physically restricting, but also very ergonomic and time-consuming. In addition, this manual operation can sometimes cause local damage to the upholstery of the seat and / or backrest in the vicinity of the passage and / or folds which adversely affect the impression of quality.
L’invention a donc notamment pour but d’améliorer la situation. The invention therefore aims in particular to improve the situation.
Elle propose notamment à cet effet un procédé destiné à permettre le positionnement d’une boucle d’une ceinture de sécurité par rapport à une face avant d’un siège de véhicule comprenant un dossier et une assise entre lesquels est défini un passage, la boucle comportant un mécanisme de verrouillage et étant solidarisée fixement à une extrémité d’un lien souple et ayant une autre extrémité solidarisée fixement à un élément du véhicule. It proposes in particular for this purpose a method intended to allow the positioning of a buckle of a seat belt with respect to a front face of a vehicle seat comprising a backrest and a seat between which a passage is defined, the buckle comprising a locking mechanism and being fixedly fixed at one end of a flexible link and having another end fixedly fixed to an element of the vehicle.
Ce procédé de positionnement se caractérise par le fait qu’il comprend :
- une première étape dans laquelle on introduit dans la boucle, initialement située derrière le passage, un pêne de verrouillage, extractible et solidarisé fixement à une première extrémité d’une lanière, afin qu’il soit verrouillé temporairement par le mécanisme de verrouillage, This positioning process is characterized by the fact that it includes: a first step in which a locking bolt, extractable and fixedly secured to a first end of a strap, is introduced into the loop, initially located behind the passage, so that it is temporarily locked by the locking mechanism,
- une deuxième étape dans laquelle on fait traverser le passage par une seconde extrémité de la lanière, opposée à la première extrémité, jusqu’à la face avant du siège, puis on tire sur cette lanière pour faire traverser le passage par la boucle et positionner cette dernière devant cette face avant dans une position finale, et - a second step in which the passage is made to cross a second end of the strap, opposite the first end, up to the front face of the seat, then pull on this strap to make the passage pass through the loop and position the latter in front of this front face in a final position, and
- une troisième étape dans laquelle on déverrouille le pêne de verrouillage afin de l’écarter, avec la lanière, de la boucle. - a third step in which the locking bolt is unlocked in order to move it away, with the strap, from the buckle.
Grâce à l’invention, le technicien peut désormais facilement faire traverser la boucle de verrouillage dans le passage du siège, sans avoir à écarter les mousses du dossier et de l’assise et sans risque d’endommager localement le revêtement de l’assise et/ou du dossier et/ou de provoquer la formation de plis. Thanks to the invention, the technician can now easily pass the locking loop through the seat passage, without having to spread the foam from the backrest and the seat and without the risk of locally damaging the seat cover and / or the backrest and / or cause the formation of folds.
Le procédé de positionnement selon l’invention peut comporter d’autres caractéristiques qui peuvent être prises séparément ou en combinaison, et notamment : The positioning method according to the invention may include other characteristics which can be taken separately or in combination, and in particular:
- dans sa deuxième étape on peut introduire la seconde extrémité de la lanière dans le passage en la poussant d’une face arrière du siège vers la face avant de ce dernier ; - In its second stage, the second end of the strap can be introduced into the passage by pushing it from a rear face of the seat towards the front face of the latter;
- en variante, dans sa deuxième étape on peut faire traverser le passage, de la face avant vers une face arrière du siège, par une tige fine munie d’une extrémité de couplage, puis on peut coupler cette dernière à la seconde extrémité de la lanière, puis on peut tirer sur la tige du côté de la face avant jusqu’à ce que la seconde extrémité débouche au niveau de cette face avant, puis soit on peut poursuivre la traction avec la tige, soit on peut découpler cette dernière de la seconde extrémité de la lanière afin de tirer sur cette dernière, pour faire traverser le passage par la boucle. - as a variant, in its second stage, the passage can be made to cross, from the front face to a rear face of the seat, by a thin rod provided with a coupling end, then the latter can be coupled to the second end of the strap, then you can pull the rod from the side of the front face until the second end opens at this front face, then either you can continue pulling with the rod, or you can decouple the latter from the second end of the strap in order to pull on the latter, to make the loop pass through the passage.
L’invention propose également un dispositif destiné à positionner une boucle d’une ceinture de sécurité par rapport à une face avant d’un siège de véhicule comprenant un dossier et une assise entre lesquels est défini un
passage, la boucle comportant un mécanisme de verrouillage et étant solidarisée fixement à une extrémité d’un lien souple et ayant une autre extrémité solidarisée fixement à un élément du véhicule. The invention also provides a device intended to position a buckle of a seat belt with respect to a front face of a vehicle seat comprising a backrest and a seat between which is defined a passage, the loop comprising a locking mechanism and being fixedly secured to one end of a flexible link and having another end fixedly secured to an element of the vehicle.
Ce dispositif de positionnement se caractérise par le fait qu’il comprend : This positioning device is characterized by the fact that it includes:
- un pêne de verrouillage extractible et propre à être introduit dans la boucle afin d’être verrouillé temporairement par le mécanisme de verrouillage, et - an extractable locking bolt suitable for being inserted into the loop in order to be temporarily locked by the locking mechanism, and
- une lanière comprenant une première extrémité solidarisée fixement au pêne et une seconde extrémité libre, opposée à la première extrémité et propre, une fois le verrouillage temporaire réalisé, à traverser le passage jusqu’à la face avant du siège puis, lorsqu’elle est tirée, à faire traverser la boucle par le passage pour la positionner devant cette face avant dans une position finale. - a strap comprising a first end fixedly fixed to the bolt and a second free end, opposite the first end and clean, once the temporary locking has been carried out, to cross the passage to the front face of the seat then, when it is pulled, to make the loop pass through the passage to position it in front of this front face in a final position.
Par exemple, la seconde extrémité de la lanière peut comprendre une boucle fermée facilitant la traction de cette dernière par au moins un doigt d’une personne réalisant le positionnement. For example, the second end of the strap may include a closed loop facilitating the traction of the latter by at least one finger of a person performing the positioning.
Egalement par exemple, il peut aussi comprendre une tige fine munie d’une extrémité de couplage destinée à être couplée à la seconde extrémité de la lanière, après avoir traversé le passage de la face avant vers une face arrière du siège, et à être tirée du côté de la face avant jusqu’à ce que la seconde extrémité débouche au niveau de cette face avant. Also for example, it can also include a thin rod provided with a coupling end intended to be coupled to the second end of the strap, after having passed through the passage from the front face to a rear face of the seat, and to be pulled on the side of the front face until the second end opens at this front face.
D’autres caractéristiques et avantages de l’invention apparaîtront à l’examen de la description détaillée ci-après, et des dessins annexés, sur lesquels : Other characteristics and advantages of the invention will appear on examining the detailed description below, and the attached drawings, in which:
- la figure 1 illustre de façon schématique, dans une vue en perspective, un exemple de réalisation d’un dispositif de positionnement selon l’invention, avant son couplage à une boucle de ceinture de sécurité d’un véhicule,FIG. 1 schematically illustrates, in a perspective view, an exemplary embodiment of a positioning device according to the invention, before it is coupled to a seat belt buckle of a vehicle,
- la figure 2 illustre de façon schématique, dans une vue en perspective, le dispositif de positionnement de la figure 1 , après son couplage à une boucle de ceinture de sécurité d’un véhicule mais avant que l’extrémité libre de sa lanière traverse le passage d’un siège de ce véhicule, - Figure 2 schematically illustrates, in a perspective view, the positioning device of Figure 1, after its coupling to a seat belt buckle of a vehicle but before the free end of its strap crosses the passage of a seat of this vehicle,
- la figure 3 illustre de façon schématique, dans une vue en coupe longitudinale, une petite partie d’un plancher de véhicule sur lequel est installé
un siège muni d’un passage que commence à traverser une boucle de ceinture de sécurité grâce à la traction exercée sur le dispositif de positionnement de la figure 1 , - Figure 3 illustrates schematically, in a longitudinal sectional view, a small part of a vehicle floor on which is installed a seat provided with a passage which begins to pass through a seat belt buckle thanks to the traction exerted on the positioning device of FIG. 1,
- la figure 4 illustre de façon schématique, dans une vue en coupe longitudinale, la partie du plancher de la figure 3 une fois la boucle positionnée devant la face avant du siège et une fois le dispositif de positionnement découplé de cette boucle, et FIG. 4 schematically illustrates, in a longitudinal section view, the part of the floor of FIG. 3 once the loop is positioned in front of the front face of the seat and once the positioning device is decoupled from this loop, and
- la figure 5 illustre schématiquement un exemple d’algorithme mettant en œuvre un procédé de positionnement selon l’invention. - Figure 5 schematically illustrates an example of an algorithm implementing a positioning method according to the invention.
L’invention a notamment pour but de proposer un procédé de positionnement, et un dispositif de positionnement 1 associé, destinés à permettre le positionnement d’une boucle de verrouillage 2 d’une ceinture de sécurité 3 d’un véhicule devant la face avant 4 d’un siège 5 de ce dernier. The object of the invention is in particular to propose a positioning method, and an associated positioning device 1, intended to allow the positioning of a locking loop 2 of a seat belt 3 of a vehicle in front of the front face 4 of a seat 5 of the latter.
Dans ce qui suit, on considère, à titre d’exemple non limitatif, que le véhicule est de type automobile. Il s’agit par exemple d’une voiture. Mais l’invention n’est pas limitée à ce type de véhicule. Elle concerne en effet tout type de véhicule possédant au moins un siège devant être associé à au moins une ceinture de sécurité dont la boucle de verrouillage doit traverser un passage défini entre son assise et son dossier. Par conséquent, elle concerne au moins les véhicules terrestres et les véhicules fluviaux (ou maritimes). In what follows, it is considered, by way of nonlimiting example, that the vehicle is of the automobile type. This is for example a car. However, the invention is not limited to this type of vehicle. It relates in fact to any type of vehicle having at least one seat to be associated with at least one seat belt, the locking loop of which must pass through a passage defined between its seat and its backrest. Consequently, it concerns at least land vehicles and river (or maritime) vehicles.
On a schématiquement représenté sur les figures 3 et 4 une petite partie d’un plancher 6 d’un véhicule sur lequel est installé un siège 5 muni d’un passage 7 destiné à permettre le passage d’une boucle (de verrouillage) 2 d’une ceinture de sécurité 3, solidarisée fixement à une extrémité d’un lien (ou brin) 8 souple et dont l’autre extrémité est solidarisée fixement à un élément du véhicule, par exemple via une patte de fixation 9. There is schematically shown in Figures 3 and 4 a small part of a floor 6 of a vehicle on which is installed a seat 5 provided with a passage 7 intended to allow the passage of a loop (locking) 2 d 'A seat belt 3, fixedly secured to one end of a flexible link (or strand) 8 and the other end of which is fixedly secured to an element of the vehicle, for example via a fixing lug 9.
On notera que dans l’exemple illustré non limitativement sur les figures 3 et 4 cet élément du véhicule est le plancher 6. Mais il pourrait s’agir d’un autre élément du véhicule. Note that in the example illustrated without limitation in Figures 3 and 4 this element of the vehicle is the floor 6. But it could be another element of the vehicle.
Le lien (ou brin) 8 peut être une sangle ou un câble. The link (or strand) 8 can be a strap or a cable.
La patte de fixation 9 est solidarisée, par exemple par vissage, à l’élément 6 (ici le plancher), derrière la face arrière 10 du siège 5 ou sous ce dernier (5) (comme illustré non limitativement sur les figures 3 et 4).
Le siège 5 comprend une assise 1 1 et un dossier 12 entre lesquels est défini le passage 7 qui doit être traversé par la boucle (de verrouillage) 2 grâce à la mise en œuvre du procédé de positionnement selon l’invention. Cette boucle 2 est destinée, une fois correctement positionnée devant la face avant 4 du siège 5, à verrouiller, grâce à un mécanisme de verrouillage qu’elle comprend, un pêne de verrouillage monté de façon coulissante sur la sangle de sa ceinture de sécurité 3 (associée au siège 5) pour protéger un passager assis sur ce dernier (5). The fixing lug 9 is secured, for example by screwing, to the element 6 (here the floor), behind the rear face 10 of the seat 5 or under the latter (5) (as illustrated without limitation in Figures 3 and 4 ). The seat 5 includes a seat 1 1 and a backrest 12 between which is defined the passage 7 which must be crossed by the loop (locking) 2 through the implementation of the positioning method according to the invention. This loop 2 is intended, once correctly positioned in front of the front face 4 of the seat 5, to lock, thanks to a locking mechanism which it comprises, a locking bolt slidably mounted on the strap of its seat belt 3 (associated with seat 5) to protect a passenger seated on the latter (5).
Le procédé de positionnement, selon l’invention, comprend trois étapes 100 à 120 qui peuvent être mises en œuvre au moyen d’un dispositif de positionnement 1 . The positioning method according to the invention comprises three steps 100 to 120 which can be implemented by means of a positioning device 1.
Un exemple d’algorithme permettant de mettre en œuvre le procédé de positionnement est illustré sur la figure 5. Par ailleurs, on a schématiquement représenté sur les figures 1 à 3 un exemple de réalisation d’un dispositif de positionnement 1 . Comme illustré, ce dernier (1 ) comprend un pêne de verrouillage 13 et une lanière 14 solidarisés entre eux. An example of an algorithm making it possible to implement the positioning method is illustrated in FIG. 5. Furthermore, an exemplary embodiment of a positioning device 1 has been schematically represented in FIGS. 1 to 3. As illustrated, the latter (1) comprises a locking bolt 13 and a strap 14 secured to each other.
Ce pêne de verrouillage 13 est similaire à celui qui doit être monté coulissant sur la sangle de la ceinture de sécurité 3. On notera seulement que ce pêne de verrouillage 13 peut éventuellement se différencier de celui qui est monté coulissant sur la sangle par l’absence de coque d’habillage en matière plastique au niveau de sa tête qui est solidarisée à une première extrémité 15 de la lanière 14. This locking bolt 13 is similar to that which must be slidably mounted on the strap of the seat belt 3. It will only be noted that this locking bolt 13 may possibly differ from that which is slidably mounted on the strap by the absence plastic covering shell at its head which is secured to a first end 15 of the strap 14.
Le pêne de verrouillage 13 est donc extractible et propre à être introduit dans la boucle 2 afin d’être verrouillé temporairement par son mécanisme de verrouillage, comme on le verra plus loin. The locking bolt 13 is therefore extractable and suitable for being inserted into the loop 2 in order to be temporarily locked by its locking mechanism, as will be seen below.
Par exemple, la lanière 14 peut être réalisée dans le même matériau que celui qui est utilisé pour la sangle de la ceinture de sécurité 3. Mais cela n’est pas obligatoire. Ainsi, il pourrait s’agir d’un cordon, éventuellement tressé, ou d’un câble. For example, the strap 14 can be made of the same material as that used for the strap of the seat belt 3. But this is not compulsory. So it could be a cord, possibly braided, or a cable.
On notera que le procédé de positionnement débute quand un technicien (ou une personne), tenant dans une main le pêne de verrouillage 13 du dispositif de positionnement 1 , se saisit avec son autre main de la boucle 2, alors qu’elle est initialement située derrière le passage 7, c’est-à-dire du côté de
la face arrière 10 du siège 5 ou sous ce dernier (5). It will be noted that the positioning process begins when a technician (or a person), holding in one hand the locking bolt 13 of the positioning device 1, grasps the loop 2 with his other hand, while it is initially located behind passage 7, i.e. on the side of the rear face 10 of the seat 5 or under the latter (5).
Dans une première étape 100 du procédé de positionnement, on (le technicien) introduit dans la boucle 2 le pêne de verrouillage 13 afin qu’il soit verrouillé temporairement par le mécanisme de verrouillage qu’elle comprend. In a first step 100 of the positioning process, the (technician) introduces into the loop 2 the locking bolt 13 so that it is temporarily locked by the locking mechanism which it comprises.
Dans une deuxième étape 1 10 du procédé de positionnement, on (le technicien) commence par faire traverser le passage 7 par une seconde extrémité 16 de la lanière 14, qui est opposée à la première extrémité 15, jusqu’à ce qu’elle débouche au niveau de la face avant 4 du siège 5. Puis, on (le technicien) tire sur cette lanière 14 du côté de la face avant 4 (comme illustré par la flèche 17 de la figure 3), pour faire traverser le passage 7 par la boucle 2 et positionner cette dernière (2) devant cette face avant 4 dans une position finale (illustrée sur la figure 4). In a second step 1 10 of the positioning process, we (the technician) begin by passing the passage 7 through a second end 16 of the strap 14, which is opposite to the first end 15, until it opens out. at the front face 4 of the seat 5. Then, we (the technician) pull on this strap 14 on the side of the front face 4 (as illustrated by the arrow 17 in FIG. 3), to make the passage 7 pass through loop 2 and position the latter (2) in front of this front face 4 in a final position (illustrated in FIG. 4).
Dans une troisième étape 120 du procédé de positionnement, on (le technicien) déverrouille le pêne de verrouillage 13, en actionnant l’organe de commande du mécanisme de verrouillage que comprend la boucle 2, afin d’écarter ce pêne de verrouillage 13, avec la lanière 14 associée, de la boucle 2. La boucle 2 est alors correctement positionnée dans sa position finale par rapport au siège 5 (voir figure 4). In a third step 120 of the positioning method, one (the technician) unlocks the locking bolt 13, by actuating the control member of the locking mechanism that includes the loop 2, in order to move this locking bolt 13 apart, with the associated strap 14, of the loop 2. The loop 2 is then correctly positioned in its final position relative to the seat 5 (see FIG. 4).
Grâce à cette traction exercée sur la boucle 2 de l’arrière du siège 5 vers l’avant de ce dernier (5), au moyen de la lanière 14, le technicien peut désormais facilement faire traverser la boucle 2 dans le passage 7, sans avoir à écarter les mousses du dossier 12 et de l’assise 1 1 , et sans risque d’endommager localement le revêtement de l’assise 1 1 et/ou du dossier 12 au voisinage du passage 7, et/ou de provoquer la formation de plis de nature à nuire à l’impression de qualité. L’ergonomie du positionnement est donc notablement améliorée, et la durée du positionnement est réduite. Thanks to this traction exerted on the loop 2 from the rear of the seat 5 towards the front of the latter (5), by means of the strap 14, the technician can now easily make loop 2 pass through in passage 7, without have to separate the foam from the backrest 12 and the seat 1 1, and without the risk of locally damaging the covering of the seat 1 1 and / or the backrest 12 in the vicinity of the passage 7, and / or cause formation wrinkles that could affect the impression of quality. The ergonomics of positioning are therefore significantly improved, and the duration of positioning is reduced.
Par exemple, et comme illustré non limitativement sur les figures 1 à 3, la seconde extrémité 16 de la lanière 14 peut avantageusement comprendre une boucle fermée 2 facilitant la traction de cette dernière (14) par au moins un doigt de la personne (le technicien) qui réalise le positionnement de la boucle 2. On comprendra qu’une telle boucle fermée, qui constitue une espèce de poignée, permet au technicien de tirer plus facilement la lanière 14 et donc la boucle 2 lors de sa traversée du passage 7.
On notera que dans la deuxième étape 110 on (le technicien) peut introduire la seconde extrémité 16 de la lanière 14 dans le passage 7 en la poussant de la face arrière 10 du siège 5 vers la face avant 4 de ce dernier (5). Cette opération s’effectue facilement manuellement du fait de la faible épaisseur de la lanière 14. For example, and as illustrated without limitation in Figures 1 to 3, the second end 16 of the strap 14 may advantageously include a closed loop 2 facilitating the traction of the latter (14) by at least one finger of the person (the technician ) which realizes the positioning of the loop 2. It will be understood that such a closed loop, which constitutes a kind of handle, allows the technician to more easily pull the strap 14 and therefore the loop 2 during its crossing of the passage 7. Note that in the second step 110 (the technician) can introduce the second end 16 of the strap 14 into the passage 7 by pushing it from the rear face 10 of the seat 5 towards the front face 4 of the latter (5). This operation is easily carried out manually due to the small thickness of the strap 14.
En variante de cette deuxième étape 110, le dispositif de positionnement 1 pourrait comporter une tige fine munie d’une extrémité de couplage destinée à être couplée à la seconde extrémité 16 de la lanière 14, après que le technicien lui ait fait traverser le passage 7 de la face avant 4 vers la face arrière 10 du siège 5. Dans ce cas, une fois ce couplage effectué, le technicien n’a plus qu’à tirer sur la tige du côté de la face avant 4 du siège 5 jusqu’à ce que la seconde extrémité 16 débouche au niveau de cette face avant 4. Puis, il peut soit poursuivre la traction avec la tige, soit découpler cette dernière de la seconde extrémité 16 de la lanière 14 afin de tirer sur cette dernière (14), pour faire traverser le passage 7 par la boucle 2.
As a variant of this second step 110, the positioning device 1 could comprise a fine rod provided with a coupling end intended to be coupled to the second end 16 of the strap 14, after the technician has made it pass through the passage 7 from the front face 4 towards the rear face 10 of the seat 5. In this case, once this coupling has been carried out, the technician only has to pull the rod on the side of the front face 4 of the seat 5 until that the second end 16 opens at this front face 4. Then, it can either continue pulling with the rod, or decouple the latter from the second end 16 of the strap 14 in order to pull on the latter (14), to make loop 2 pass through passage 7.
