Description

Description Description
Titre de l'invention : Véhicule comprenant un dispositif de retenue de la roue de secours Title of the invention: Vehicle comprising a device for retaining the spare wheel
[0001] La présente invention concerne un véhicule comprenant un dispositif de retenue de la roue de secours. The present invention relates to a vehicle comprising a spare wheel retaining device.
[0002] Habituellement, une roue de secours est logée dans un évidement d’un plancher de coffre arrière d’un véhicule. Généralement, cette roue de secours est complètement incluse dans l’évidement, si bien que lors d’un choc arrière accidentel du véhicule contre un obstacle extérieur, ladite roue demeure logée dans cet évidement, sans risque d’en sortir et de constituer un projectile susceptible de venir impacter le dos d’un occupant qui serait assis à l’arrière du véhicule. [0002] Usually, a spare wheel is housed in a recess in the rear boot floor of a vehicle. Generally, this spare wheel is completely included in the recess, so that during an accidental rear impact of the vehicle against an external obstacle, said wheel remains housed in this recess, without risk of coming out and constituting a projectile. likely to impact the back of an occupant who is seated in the rear of the vehicle.
[0003] Or, dans le contexte d’hybridation des véhicules, consistant à adjoindre à ces véhicules une propulsion électrique d’appoint pour notamment limiter leur consommation en carburant lors de certaines phases de roulage, il a fallu fixer une batterie électrique sous le plancher du coffre arrière. Cette opération a nécessité un relèvement de ce plancher au-dessus de longerons du véhicule, entraînant une surélévation de la roue de secours dans le coffre. La roue de secours repose alors sur le plancher, sans être au moins partiellement incluse dans un évidement dudit plancher. Les conséquences d’une telle situation sont que la roue de secours n’est plus retenue dans le coffre arrière et que, dans le cas d’un choc arrière du véhicule contre un obstacle extérieur, elle peut être projetée violemment vers l’avant et venir blesser des occupants qui seraient assis à l’arrière du véhicule. [0003] However, in the context of hybridization of vehicles, consisting in adding to these vehicles a booster electric propulsion in particular to limit their fuel consumption during certain driving phases, it was necessary to fix an electric battery under the floor from the rear trunk. This operation required raising this floor above the vehicle's side members, causing the spare wheel to be raised in the boot. The spare wheel then rests on the floor, without being at least partially included in a recess of said floor. The consequences of such a situation are that the spare wheel is no longer retained in the rear boot and that, in the event of a rear impact of the vehicle against an external obstacle, it can be thrown violently forwards and injure occupants who are seated in the rear of the vehicle.
[0004] Un véhicule selon l’invention est un véhicule hybride possédant une batterie électrique sous le plancher du coffre arrière et une roue de secours logée dans ledit coffre, ledit véhicule étant configuré pour empêcher la roue de secours d’être projetée vers l’avant dans le cas d’un choc arrière dudit véhicule contre un obstacle extérieur. A vehicle according to the invention is a hybrid vehicle having an electric battery under the floor of the rear boot and a spare wheel housed in said boot, said vehicle being configured to prevent the spare wheel from being thrown front in the event of a rear impact of said vehicle against an external obstacle.
[0005] Afin de bien comprendre le positionnement des différentes pièces impliquées dans un véhicule selon l’invention, la description est réalisée en faisant référence à un repère orthonormé direct XYZ lié au véhicule, dans lequel X est un axe longitudinal avant-arrière du véhicule orienté vers l’arrière, Y est un axe transversal orienté vers la droite du véhicule et Z est un axe vertical dirigé vers le haut. In order to fully understand the positioning of the various parts involved in a vehicle according to the invention, the description is made with reference to a direct orthonormal reference XYZ linked to the vehicle, in which X is a longitudinal front-rear axis of the vehicle directed towards the rear, Y is a transverse axis directed towards the right of the vehicle and Z is a vertical axis directed upwards.
[0006] L’invention a pour objet un véhicule hybride possédant un coffre arrière délimité par un plancher arrière, et une batterie électrique fixée sous ledit plancher arrière, ledit véhicule comprenant en outre une roue de secours reposant sur ledit plancher arrière et émergeant de celui-ci. The invention relates to a hybrid vehicle having a rear trunk delimited by a rear floor, and an electric battery fixed under said rear floor, said vehicle further comprising a spare wheel resting on said rear floor and emerging from that -this.
[0007] Selon l’invention, le véhicule comprend une butée de retenue de la roue de secours fixée au plancher arrière entre ladite roue de secours et une rangée arrière de sièges, ladite butée de retenue ayant pour fonction d’empêcher la roue de secours de se déplacer vers la rangée arrière de sièges dans le cas d’un choc arrière dudit véhicule contre un obstacle extérieur. En effet, lors d’un tel choc, la roue de secours peut se transformer en projectile dangereux susceptible de venir impacter le dos d’un occupant qui serait assis sur la rangée arrière de sièges, et le blesser gravement. Cette butée de retenue est solidement arrimée au plancher arrière du coffre arrière, de manière à ne pas être déplacée lors d’un choc accidentel du véhicule contre un obstacle extérieur. En effet, puisqu’elle a pour vocation de stopper la course de la roue de secours lors d’un tel choc, il ne faut pas qu’elle puisse elle-même constituer un projectile en se déplaçant. De même, cette butée de retenue est conçue pour ne pas se déformer lors de ce choc, afin d’éviter la situation pour laquelle elle ne serait plus en mesure de retenir la roue de secours. Il est supposé que l’arrimage de la batterie électrique sous le plancher arrière du coffre arrière a entrainé un relèvement dudit plancher arrière, plaçant la roue de secours dans la catégorie des sources de danger potentiel pour les occupants de la rangée arrière lors d’un choc arrière du véhicule. L’expression « rangée arrière de sièges » est une expression générique désignant la rangée de sièges située juste devant le coffre arrière. Si le véhicule ne possède qu’une seule rangée de sièges comprenant un siège conducteur et un siège passager, l’expression « rangée arrière de sièges » peut désigner cette rangée unique de sièges. De même, cette expression peut également désigner une banquette arrière. Afin de bien comprendre la configuration d’un véhicule selon l’invention, il faut rappeler que la roue de secours présente un axe de révolution et que, lorsqu’elle repose sur le plancher arrière, cet axe de révolution s’étend perpendiculairement audit plancher. Autrement dit, il peut être supposé que la roue s’inscrive dans un plan, et que, lorsqu’elle repose sur le plancher arrière, ledit plan est parallèle audit plancher. [0007] According to the invention, the vehicle comprises a spare wheel retaining stop fixed to the rear floor between said spare wheel and a rear row of seats, said retaining stop having the function of preventing the spare wheel to move towards the rear row of seats in the event of a rear impact of said vehicle against an external obstacle. In fact, during such an impact, the spare wheel may turn into a dangerous projectile liable to impact the back of an occupant who is seated on the rear row of seats, and seriously injure him. This retaining stop is securely fastened to the rear floor of the trunk, so as not to be moved in the event of an accidental impact of the vehicle against an external obstacle. Indeed, since its purpose is to stop the travel of the spare wheel during such an impact, it must not itself be able to form a projectile by moving. Likewise, this retaining abutment is designed not to deform during this impact, in order to avoid the situation in which it would no longer be able to retain the spare wheel. It is assumed that the stowage of the electric battery under the rear floor of the rear boot caused the said rear floor to rise, placing the spare wheel in the category of sources of potential danger for the occupants of the rear row during a rear impact of the vehicle. The expression "rear row of seats" is a generic expression designating the row of seats located just in front of the rear boot. If the vehicle has only one row of seats comprising a driver's seat and a passenger seat, the expression "rear row of seats" may designate this single row of seats. Likewise, this expression can also refer to a rear seat. In order to fully understand the configuration of a vehicle according to the invention, it should be remembered that the spare wheel has an axis of revolution and that, when it rests on the rear floor, this axis of revolution extends perpendicularly to said floor. In other words, it can be assumed that the wheel is inscribed in a plane, and that, when it rests on the rear floor, said plane is parallel to said floor.
[0008] Selon une caractéristique possible de l’invention, la hauteur de la butée de retenue est supérieure ou égale à la hauteur de la roue de secours émergeant du plancher arrière. En effet, il faut éliminer tout risque de voir la roue de secours passer par-dessus la butée de retenue lors d’un choc du véhicule, car dans ce cas, la roue pourrait être projetée de façon aléatoire dans le véhicule et causer des dommages corporels importants. La hauteur de la roue correspond à la largeur d’un pneu de ladite roue. According to a possible characteristic of the invention, the height of the retaining stop is greater than or equal to the height of the spare wheel emerging from the rear floor. In fact, it is necessary to eliminate any risk of the spare wheel going over the retaining stop during a vehicle impact, because in this case the wheel could be thrown randomly into the vehicle and cause damage. important bodies. The height of the wheel corresponds to the width of a tire of said wheel.
[0009] Selon une caractéristique possible de l’invention, la dimension de la butée de retenue considérée suivant un axe transversal Y du véhicule est supérieure ou égale à un diamètre de la roue de secours. De même, il faut également empêcher que la roue de secours ne puisse s’échapper sur les côtés de la butée de retenue. [0009] According to a possible characteristic of the invention, the dimension of the retaining stop considered along a transverse axis Y of the vehicle is greater than or equal to a diameter of the spare wheel. In the same way, it must also be prevented that the spare wheel cannot escape on the sides of the retaining stop.
[0010] Selon une caractéristique possible de l’invention, la butée de retenue présente une partie inclinée s’étendant d’une zone du plancher arrière située devant la roue de secours vers une zone avant supérieure de la roue de secours. Lors d’un choc du véhicule, cette partie inclinée va stopper la course vers l’avant de la roue de secours, en ayant tendance à la rabaisser vers le plancher arrière du coffre arrière. [0010] According to a possible feature of the invention, the retaining stop has an inclined part extending from a zone of the rear floor located in front of the spare wheel towards an upper front zone of the spare wheel. In the event of a vehicle impact, this inclined part will stop the forward travel of the spare wheel, tending to lower it towards the rear floor of the boot.
[0011] Selon une caractéristique possible de l’invention, la dimension de la partie inclinée de la butée de retenue considérée suivant un axe transversal Y du véhicule est supérieure ou égale à un diamètre de la roue de secours. According to a possible characteristic of the invention, the dimension of the inclined part of the retaining stop considered along a transverse axis Y of the vehicle is greater than or equal to a diameter of the spare wheel.
[0012] Selon une caractéristique possible de l’invention, la partie inclinée de la butée de retenue présente plusieurs segments tubulaires disposés en treillis. De cette manière, la butée de retenue présente une résistance mécanique accrue, lui conférant un caractère de grande robustesse et d’indéformabilité. Une telle butée va bloquer efficacement toute course vers l’avant de la roue de secours lors d’un choc du véhicule, en ne se déformant pas. De plus, une telle butée de retenue ajourée va contribuer à alléger le véhicule. [0013] Selon une caractéristique possible de l’invention, la butée de retenue présente une paroi de fixation située devant la partie inclinée et en continuité avec celle-ci, ladite paroi de fixation étant orientée par rapport à la partie inclinée de telle sorte qu’elle établisse un contact surfacique avec une surface du plancher arrière. Cette paroi de fixation va définir un plan d’interface avec une surface du plancher arrière, améliorant les conditions de contact entre la butée de retenue et le plancher arrière du coffre arrière. According to a possible characteristic of the invention, the inclined part of the retaining abutment has several tubular segments arranged in a latticework. In this way, the retaining abutment has increased mechanical strength, giving it a character of great robustness and non-deformability. Such a stop will effectively block any forward travel of the spare wheel during a vehicle impact, while not deforming. In addition, such a perforated retaining stop will contribute to lightening the vehicle. According to a possible characteristic of the invention, the retaining abutment has a fixing wall located in front of the inclined part and in continuity with the latter, said fixing wall being oriented with respect to the inclined part so that it establishes surface contact with a surface of the rear floor. This fixing wall will define an interface plane with a surface of the rear floor, improving the conditions of contact between the retaining abutment and the rear floor of the rear trunk.
[0014] Selon une caractéristique possible de l’invention, la paroi de fixation s’étend suivant un axe transversal Y du véhicule et possède une pluralité d’orifices par lesquels passent des vis pour assurer la fixation de la butée de retenue au plancher arrière. Ce mode de fixation est particulièrement mais non exclusivement adapté à un véhicule selon l’invention. Une fixation par soudure peut également être envisagée si les matériaux de la butée de retenue et du plancher sont compatibles pour une telle soudure. [0014] According to a possible characteristic of the invention, the fixing wall extends along a transverse axis Y of the vehicle and has a plurality of holes through which screws pass to ensure the fixing of the retaining stop to the rear floor . This method of attachment is particularly but not exclusively suitable for a vehicle according to the invention. Fixing by welding can also be envisaged if the materials of the retaining abutment and of the floor are compatible for such a weld.
[0015] Selon une caractéristique possible de l’invention, la butée de retenue est métallique. [0015] According to a possible characteristic of the invention, the retaining abutment is metallic.
[0016] Selon une caractéristique possible de l’invention, la butée de retenue comprend un fil rigide formant une boucle et recouvrant la roue de secours, ledit fil ayant pour fonction de stabiliser la position de la roue de secours sur le plancher arrière lors d’une utilisation routinière dudit véhicule. Ce fil rigide contribue à stabiliser la position de la roue de secours dans le coffre arrière du véhicule, lors d’une phase de roulage normale du véhicule mais ne joue aucun rôle particulier lors d’un choc accidentel du véhicule contre un obstacle extérieur. Avantageusement, ce fil doit être soulevée manuellement pour pouvoir retirer la roue de secours du coffre arrière. According to a possible characteristic of the invention, the retaining stop comprises a rigid wire forming a loop and covering the spare wheel, said wire having the function of stabilizing the position of the spare wheel on the rear floor during routine use of said vehicle. This rigid wire helps to stabilize the position of the spare wheel in the rear boot of the vehicle, during normal vehicle driving, but plays no particular role in the event of an accidental impact of the vehicle against an external obstacle. Advantageously, this wire must be raised manually to be able to remove the spare wheel from the rear boot.
[0017] Un véhicule selon l’invention présente l’avantage de posséder une roue de secours ainsi qu’une batterie électrique placée sous le plancher arrière du coffre arrière, en respectant la sécurité des passagers grâce à une mise en place judicieuse d’une butée de retenue de la roue de secours. De cette manière, la roue de secours ne représente plus un danger pour les occupants du véhicule dans le cas d’un choc accidentel du véhicule contre un obstacle extérieur. Il a de plus l’avantage de posséder une butée de retenue ayant une géométrie optimisée, pour permettre à ladite butée de retenir efficacement la roue de secours, tout en étant légère. [0017] A vehicle according to the invention has the advantage of having a spare wheel as well as an electric battery placed under the rear floor of the rear trunk, respecting the safety of the passengers thanks to a judicious installation of a spare wheel retaining stop. In this way, the spare wheel no longer represents a danger for the occupants of the vehicle in the event of an accidental impact of the vehicle against an external obstacle. It also has the advantage of having a retaining abutment having a geometry optimized, to allow said stopper to effectively retain the spare wheel, while being light.

This trunk 2 is delimited by a rear floor 7 extending in a horizontal plane when the vehicle 1 itself rests on horizontal ground.
[0025] En se référant à la figure 4, un véhicule 1 selon l’invention est un véhicule hybride comprenant une batterie électrique 8 pouvant par exemple être une batterie de 200V. Cette batterie électrique 8 devant être placée sous le plancher arrière 7 du coffre arrière 2, il a fallu surélever ledit plancher arrière 7 et l’amener ainsi au-dessus de deux longerons dudit véhicule 1 . Referring to Figure 4, a vehicle 1 according to the invention is a hybrid vehicle comprising an electric battery 8 which can for example be a 200V battery. This electric battery 8 having to be placed under the rear floor 7 of the rear trunk 2, it was necessary to raise said rear floor 7 and thus bring it above two side members of said vehicle 1 .
[0026] En se référant aux figures 1 à 4, un véhicule 1 selon l’invention possède également une roue de secours 9, qui est logée dans le coffre arrière 2. Mais en raison de la présence de la batterie électrique 8 sous le plancher arrière 7, il n’est plus possible de loger cette roue de secours 9 dans un évidement dudit plancher arrière 7. La roue de secours 9 se retrouve alors fixée au plancher arrière 7 surélevé, sans être placée dans un évidement dudit plancher arrière 7. Dans ces conditions, dans le cas d’un choc arrière du véhicule 1 contre un obstacle extérieur, la roue de secours 9 risque de se détacher du plancher arrière 7, et d’être ensuite projetée vers l’avant en direction du dos d’un occupant qui serait assis sur un siège 4, 5, 6 de la rangée 3 arrière. Cette roue de secours 9 deviendrait alors assimilable à un projectile, susceptible de causer des blessures graves audit occupant. Pour bien préciser le positionnement de la roue de secours 9 dans le coffre 2, il faut rappeler que cette roue de secours 9 présente un axe de révolution. Elle est alors placée dans le coffre 2 arrière, de sorte que ledit axe de révolution s’étende perpendiculairement au plancher arrière 7. Autrement dit, on peut supposer que la roue de secours 9 s’inscrive dans un plan, et la roue de secours 9 est placée dans le coffre 2 de sorte que ledit plan soit parallèle audit plancher 7. Referring to Figures 1 to 4, a vehicle 1 according to the invention also has a spare wheel 9, which is housed in the rear trunk 2. But due to the presence of the electric battery 8 under the floor rear 7, it is no longer possible to house this spare wheel 9 in a recess of said rear floor 7. The spare wheel 9 is then fixed to the raised rear floor 7, without being placed in a recess of said rear floor 7. Under these conditions, in the event of a rear impact of the vehicle 1 against an external obstacle, the spare wheel 9 risks detaching from the rear floor 7, and to then be thrown forward in the direction of the back of an occupant who would be seated on a seat 4, 5, 6 of row 3 behind. This spare wheel 9 would then become comparable to a projectile, liable to cause serious injury to said occupant. To clearly specify the positioning of the spare wheel 9 in the trunk 2, it must be remembered that this spare wheel 9 has an axis of revolution. It is then placed in the rear trunk 2, so that said axis of revolution extends perpendicularly to the rear floor 7. In other words, it can be assumed that the spare wheel 9 is inscribed in a plane, and the spare wheel 9 is placed in the trunk 2 so that said plane is parallel to said floor 7.
[0027] Afin d’empêcher cette roue de secours 9 d’être brutalement projetée vers l’avant dans le cas d’un choc arrière du véhicule contre un obstacle extérieur, un véhicule 1 selon l’invention met en œuvre une butée de retenue 10 destinée à bloquer ladite roue de secours 9 afin de l’empêcher de venir impacter le dos d’un occupant. [0027] In order to prevent this spare wheel 9 from being suddenly thrown forward in the event of a rear impact of the vehicle against an external obstacle, a vehicle 1 according to the invention implements a retaining stop 10 intended to block said spare wheel 9 in order to prevent it from impacting the back of an occupant.
[0028] En se référant aux figures 1 , 2, 3 et 5, cette butée de retenue 10 comprend une partie avant 11 , destinée à venir se placer devant la roue de secours 9 entre ladite roue de secours 9 et la rangée 3 arrière de sièges 4, 5, 6, et une partie arrière 12, destinée à recouvrir la roue de secours 9. [0028] Referring to Figures 1, 2, 3 and 5, this retaining stop 10 comprises a front part 11, intended to be placed in front of the spare wheel 9 between said spare wheel 9 and the rear row 3 of seats 4, 5, 6, and a rear part 12, intended to cover the spare wheel 9.
[0029] La partie avant 11 présente une zone centrale 13 considérée le long d’un axe transversal Y du véhicule 1 , qui est composée de plusieurs segments tubulaires 14 disposés en treillis. Ces segments 14 s’inscrivent dans un même plan, qui est incliné par rapport au plancher arrière 7. En effet, ce plan prend naissance sur une zone du plancher arrière 7 située à l’avant de la roue de secours 9, et s’étend de façon rectiligne jusqu’à une zone avant supérieure de ladite roue de secours 9. The front part 11 has a central zone 13 considered along a transverse axis Y of the vehicle 1, which is composed of several tubular segments 14 arranged in a trellis. These segments 14 are part of the same plane, which is inclined with respect to the rear floor 7. Indeed, this plane originates in a zone of the rear floor 7 located at the front of the spare wheel 9, and extends straight to an upper front area of said spare wheel 9.
[0030] En se référant aux figures 3 et 5, la partie avant 11 comprend une paroi de fixation 30 située devant la zone centrale inclinée 13 et en continuité avec celle- ci. Cette paroi de fixation 30, qui comprend un segment central 15 bordé par deux segments latéraux inclinés 16, 17, est orientée par rapport à la zone centrale inclinée 13 de telle sorte qu’elle établisse un contact surfacique avec une surface du plancher arrière 7. Lorsque le véhicule 1 repose sur un sol horizontal, cette paroi de fixation 30 s’étend également dans un plan horizontal, de sorte que le segment central 15 soit parallèle à un axe transversal Y du véhicule en étant situé devant la zone centrale inclinée 13. Cette paroi de fixation 30 présente plusieurs orifices destinés chacun à recevoir une vis pour arrimer la butée de retenue 10 au plancher arrière 7 du coffre arrière 2. [0030] Referring to Figures 3 and 5, the front part 11 comprises a fixing wall 30 located in front of the inclined central zone 13 and in continuity therewith. This fixing wall 30, which comprises a central segment 15 bordered by two inclined lateral segments 16, 17, is oriented with respect to the inclined central zone 13 such that it establishes surface contact with a surface of the rear floor 7. When vehicle 1 rests on the ground horizontal, this fixing wall 30 also extends in a horizontal plane, so that the central segment 15 is parallel to a transverse axis Y of the vehicle while being located in front of the inclined central zone 13. This fixing wall 30 has several orifices each intended to receive a screw to secure the retaining stop 10 to the rear floor 7 of the rear boot 2.
[0031 ] En se référant aux figures 1 , 3 et 5, la butée de retenue 10 comprend un segment 18 arrière profilé, s’étendant parallèlement au segment central 15 de la paroi de fixation 30, ledit segment arrière 18 joignant deux extrémités des segments latéraux 16, 17 de ladite paroi de fixation 30, et délimitant une zone arrière supérieure du plan dans lequel s’inscrivent les segments tubulaires 14 de la zone centrale 13 de la partie avant 11 de la butée de retenue 10. [0031] Referring to Figures 1, 3 and 5, the retaining abutment 10 comprises a profiled rear segment 18, extending parallel to the central segment 15 of the fixing wall 30, said rear segment 18 joining two ends of the segments 16, 17 of said fixing wall 30, and delimiting an upper rear zone of the plane in which the tubular segments 14 of the central zone 13 of the front part 11 of the retaining abutment 10 are inscribed.
[0032] En se référant aux figures 2, 3 et 5, la partie arrière 12 comprend un fil rigide 19 formant une boucle prenant naissance en un point du segment arrière 18 et se terminant en un autre point dudit segment arrière 18. Ce fil 19 est monté pivotant sur le segment arrière 18, au niveau de ses deux points d’intersection avec ledit segment arrière. Referring to Figures 2, 3 and 5, the rear part 12 comprises a rigid wire 19 forming a loop originating at a point of the rear segment 18 and ending at another point of said rear segment 18. This wire 19 is pivotally mounted on the rear segment 18, at its two points of intersection with said rear segment.
[0033] En se référant à la figure 2, ce fil 19 recouvre la roue de secours 9 et présente une boucle secondaire 20 ayant des dimensions compatibles avec celles d’une poignée, ladite boucle secondaire 20 reposant sur une surface du plancher arrière 7 du coffre arrière 2. Ce fil 19 recouvre la roue de secours 9 afin de stabiliser la position de ladite roue de secours 9 dans le coffre 2 arrière, lors d’une phase de roulage normale du véhicule 1 . Le conducteur désirant utiliser la roue de secours 9, va se saisir de la boucle secondaire 20 du fil 19, puis va exercer un effort vers le haut de manière à faire pivoter ledit fil 19 autour du segment arrière 18. La roue de secours 9 est alors dégagée, et le conducteur peut alors s’en saisir afin de la monter sur le véhicule à la place de la roue défectueuse. Referring to Figure 2, this wire 19 covers the spare wheel 9 and has a secondary loop 20 having dimensions compatible with those of a handle, said secondary loop 20 resting on a surface of the rear floor 7 of the rear trunk 2. This wire 19 covers the spare wheel 9 in order to stabilize the position of said spare wheel 9 in the rear trunk 2, during a normal driving phase of the vehicle 1 . The driver wishing to use the spare wheel 9, will grab the secondary loop 20 of the wire 19, then will exert an effort upwards so as to make said wire 19 pivot around the rear segment 18. The spare wheel 9 is then disengaged, and the driver can then grab hold of it in order to mount it on the vehicle in place of the defective wheel.
[0034] Il est à noter que la butée de retenue 10 comprenant la partie avant 11 et la partie arrière 12 est préférentiellement réalisée en métal. It should be noted that the retaining stop 10 comprising the front part 11 and the rear part 12 is preferably made of metal.
[0035] Lorsque survient un choc arrière accidentel du véhicule 1 contre un obstacle extérieur, ledit choc s’effectuant à une certaine vitesse pouvant par exemple être supérieur à 50km/h, la roue de secours 9 qui est arrimée au plancher arrière 7 du coffre arrière 2, va avoir tendance à se déplacer brutalement vers l’avant. Mais ce mouvement brutal vers l’avant est stoppé très tôt grâce à la présence de la butée de retenue 10. En effet, à l’amorce de ce mouvement de la roue de secours 9, la partie avant de ladite roue de secours 9 va immédiatement venir s’insérer dans l’espace compris entre le plancher 7 et la zone centrale 13 inclinée de la partie avant 11 de ladite butée de retenue 10. De cette manière, la roue de secours 9 va se retrouver piégée dans cet espace, grâce à la zone centrale inclinée 13 qui a tendance à rabaisser la roue de secours 9 vers le plancher 7. [0035] When an accidental rear impact of the vehicle 1 against an external obstacle occurs, said impact taking place at a certain speed which may for example be greater than 50 km/h, the spare wheel 9 which is secured to the rear floor 7 of the rear boot 2, will tend to move forwards suddenly. But this sudden forward movement is stopped very early thanks to the presence of the retaining stop 10. Indeed, at the start of this movement of the spare wheel 9, the front part of said spare wheel 9 goes immediately fit into the space between the floor 7 and the inclined central zone 13 of the front part 11 of said retaining stop 10. In this way, the spare wheel 9 will find itself trapped in this space, thanks to the inclined central zone 13 which tends to lower the spare wheel 9 towards the floor 7.
[0036] Dans le cadre d’un véhicule selon l’invention, la butée de retenue 10 présente une grande résistance mécanique, notamment en raison de la présence des segments tubulaires 14, et est supposée ne pas se déformer lors de la survenance d’un tel choc. De même, les points d’ancrage de la butée de retenue 10 dans le plancher arrière 7 sont suffisamment solides pour empêcher ladite butée de retenue 10 de se déplacer dans le cas d’un tel choc arrière. In the context of a vehicle according to the invention, the retaining abutment 10 has a high mechanical strength, in particular due to the presence of the tubular segments 14, and is supposed not to deform when the occurrence of such a shock. Likewise, the anchoring points of the retaining stop 10 in the rear floor 7 are strong enough to prevent said retaining stop 10 from moving in the event of such a rear impact.
