Description
La présente invention concerne, de manière générale, la partie avant d’un véhicule automobile dans laquelle s’étend la colonne de direction et se rapporte plus particulièrement à une coquille d’habillage pour colonne de direction.The present invention relates, in general, to the front part of a motor vehicle in which the steering column extends and relates more particularly to a trim shell for the steering column.
Plus précisément, l’invention se rapporte à une coquille d’habillage inférieure de coquille d’habillage pour une colonne de direction d’un véhicule automobile et un procédé de fabrication associé.More specifically, the invention relates to a lower trim shell trim shell for a steering column of a motor vehicle and an associated method of manufacture.
La colonne de direction, présente sur tous les véhicules automobiles, est un élément mécanique reliant le volant de direction à la crémaillère et permet au conducteur de transmettre le mouvement de rotation à cette dernière pour l’actionnement d’une barre de direction pour le braquage des roues motrices.The steering column, present on all motor vehicles, is a mechanical element connecting the steering wheel to the rack and allows the driver to transmit the rotational movement to the latter for the actuation of a steering bar for steering driving wheels.
De ce fait, lorsque le conducteur est installé en position de conduite, la partie basse de son corps et notamment ses genoux sont positionnés sous le volant, en regard de la colonne de direction.Therefore, when the driver is installed in the driving position, the lower part of his body and in particular his knees are positioned under the steering wheel, facing the steering column.
La figure 1 illustre la structure sous le volant de direction (non représenté) d’une partie avant d’un véhicule automobile, selon l’art antérieur.Figure 1 illustrates the structure under the steering wheel (not shown) of a front part of a motor vehicle, according to the prior art.
Comme cela est représenté, la colonne de direction 1 est intégrée dans la partie avant du véhicule et une coquille d’habillage 2 s’étend de part et d’autre de la colonne de direction. La coquille d’habillage 2 comporte une coquille d’habillage inférieure 3 s’étendant le long de la colonne de direction, sous le volant, en regard du siège conducteur, et une coquille d’habillage supérieure 4 diamétralement opposée par rapport à la colonne de direction.As shown, the steering column 1 is integrated into the front part of the vehicle and a trim shell 2 extends on either side of the steering column. The trim shell 2 comprises a lower trim shell 3 extending along the steering column, under the steering wheel, facing the driver's seat, and an upper trim shell 4 diametrically opposed with respect to the column of management.
Lors d’une collision du véhicule avec un élément extérieur, les genoux du conducteur se trouvent être la première partie du corps susceptible de venir frapper contre la coquille d’habillage voire, selon l’intensité du choc, contre la colonne de direction. Compte tenu de la rigidité de la colonne et de sa forme allongée, les dommages pour le conducteur peuvent être considérables.In the event of a collision of the vehicle with an external element, the driver's knees are the first part of the body likely to strike against the trim shell or, depending on the intensity of the impact, against the steering column. Given the rigidity of the column and its elongated shape, the damage to the driver can be considerable.
Pour cette raison, il est indispensable qu’une protection limitant les risques de blessures du conducteur soit prévue dans la structure avant du véhicule.For this reason, it is essential that protection limiting the risk of injury to the driver be provided in the front structure of the vehicle.
Classiquement, comme on peut le voir sur la figure 1, un élément ou bloc de rembourrage de protection 5 est inséré entre la coquille d’habillage inférieure 3 et des éléments de structure 6 et 7.Conventionally, as can be seen in Figure 1, a protective padding element or block 5 is inserted between the lower covering shell 3 and structural elements 6 and 7.
Cependant, la fabrication du bloc de rembourrage de protection 5 en plus de la coquille d’habillage inférieure 3 rallonge et rend plus coûteuse l’étape de fabrication de la coquille d’habillage 2.However, the manufacture of the protective padding block 5 in addition to the lower covering shell 3 lengthens and makes the stage of manufacturing the covering shell 2 more expensive.
La mise en place du bloc de rembourrage de protection complexifie également l’installation de la coquille d’habillage autour de la colonne de direction 1 et nécessite la réalisation de plusieurs outillages impliquant un coût plus élevé.The installation of the protective padding block also complicates the installation of the trim shell around the steering column 1 and requires the production of several tools involving a higher cost.
L’invention a donc pour but de remédier à ces inconvénients et de proposer une protection simple et peu coûteuse à fabriquer, destinée à prévenir les dommages liés aux chocs entre les genoux d’un conducteur et la coquille d’habillage d’une colonne de direction.The object of the invention is therefore to remedy these drawbacks and to propose a protection that is simple and inexpensive to manufacture, intended to prevent damage linked to impacts between the knees of a driver and the covering shell of a column of direction.
Il est donc proposé une coquille d’habillage inférieure d’une coquille d’habillage pour colonne de direction d’un véhicule automobile, destinée à être disposée en vis-à-vis des genoux d’un conducteur installé en position de conduite, comprenant un moyen de protection des genoux du conducteur en cas de choc des genoux du conducteur avec la coquille d’habillage.There is therefore proposed a lower trim shell of a trim shell for a steering column of a motor vehicle, intended to be arranged opposite the knees of a driver installed in the driving position, comprising a means of protecting the driver's knees in the event of impact of the driver's knees with the trim shell.
En outre, ledit moyen de protection des genoux du conducteur et la coquille d’habillage inférieure sont configurés de sorte qu’ils forment une seule pièce.Furthermore, said driver's knee protection means and the lower trim shell are configured so that they form a single piece.
De préférence, le moyen de protection des genoux du conducteur et la coquille d’habillage inférieure sont formés d’un même matériau de sorte qu’ils forment une structure unique monobloc.Preferably, the driver's knee protection means and the lower trim shell are formed from the same material so that they form a single one-piece structure.
Selon un mode de réalisation, la coquille d’habillage inférieure est formée au moins en partie de polypropylène expansé EPP.According to one embodiment, the lower trim shell is formed at least in part from expanded polypropylene EPP.
Selon une caractéristique, la coquille d’habillage inférieure peut être entièrement formée en polypropylène expansé EPP.According to one feature, the lower trim shell can be formed entirely from EPP expanded polypropylene.
Avantageusement, la coquille d’habillage inférieure peut être configurée pour recevoir un ou plusieurs inserts destinés à structurer la coquille d’habillage.Advantageously, the lower trim shell can be configured to receive one or more inserts intended to structure the trim shell.
L’invention se rapporte aussi à une coquille d’habillage pour colonne de direction d’un véhicule automobile, comprenant une coquille d’habillage inférieure comme décrite précédemment. Un revêtement choisi parmi du cuir, du textile ou du polychlorure de vinyle est disposé sur la surface extérieure de la coquille d’habillage inférieure destinée à être disposée en vis-à-vis des genoux du conducteur.The invention also relates to a covering shell for the steering column of a motor vehicle, comprising a lower covering shell as described previously. A coating chosen from leather, textile or polyvinyl chloride is placed on the outer surface of the lower trim shell intended to be placed opposite the driver's knees.
L’invention concerne également un véhicule automobile comprenant une colonne de direction et une coquille d’habillage de la colonne de direction. La coquille d’habillage comporte une coquille d’habillage inférieure telle que décrite précédemment.The invention also relates to a motor vehicle comprising a steering column and a trim shell of the steering column. The trim shell has a lower trim shell as previously described.
L’invention concerne aussi un procédé de fabrication d’une coquille d’habillage inférieure de coquille d’habillage pour une colonne de direction d’un véhicule automobile.The invention also relates to a method of manufacturing a lower trim shell trim shell for a steering column of a motor vehicle.
En outre, le procédé de fabrication comprend une étape de formation d’une seule pièce formant la coquille d’habillage inférieure et un moyen de protection des genoux du conducteur.In addition, the manufacturing process includes a step of forming a single piece forming the lower trim shell and a means of protecting the driver's knees.
Avantageusement, l’étape de formation de la pièce formant la coquille d’habillage inférieure et le moyen de protection des genoux du conducteur peut être obtenue par moulage.Advantageously, the step of forming the part forming the lower trim shell and the driver's knee protection means can be obtained by molding.
De préférence, l’étape de formation de la pièce formant la coquille d’habillage inférieure et le moyen de protection des genoux du conducteur est obtenue par moulage de polypropylène expansé.Preferably, the step of forming the part forming the lower trim shell and the driver's knee protection means is obtained by molding expanded polypropylene.
D’autres buts, avantages et caractéristiques ressortiront de la description qui va suivre, donnée à titre purement illustratif et faite en référence aux dessins annexés sur lesquels :Other aims, advantages and characteristics will emerge from the description which follows, given for purely illustrative purposes and made with reference to the appended drawings in which:
Dans la suite de la description, les termes « bas » et « haut » s’entendent par rapport au repère orthogonal usuel des véhicules automobiles, représenté sur les figures 1 et 2, et comprenant :In the rest of the description, the terms "low" and "high" are understood with respect to the usual orthogonal reference of motor vehicles, represented in Figures 1 and 2, and comprising:
- un axe longitudinal X, horizontal et dirigé de l’avant vers l’arrière du véhicule ;- a longitudinal axis X, horizontal and directed from the front to the rear of the vehicle;
- un axe transversal Y, horizontal, perpendiculaire à l’axe X et dirigé de la droite à la gauche du véhicule se déplaçant vers l’avant ;- a transverse Y axis, horizontal, perpendicular to the X axis and directed from the right to the left of the vehicle moving forwards;
- un axe Z, orthogonal aux axes X et Y et vertical dirigé de bas en haut.- a Z axis, orthogonal to the X and Y axes and vertical directed from bottom to top.
La figure 2 illustre la structure d’une partie avant d’un véhicule automobile comportant une colonne de direction 8 et une coquille d’habillage 9 selon un mode de réalisation de l’invention.FIG. 2 illustrates the structure of a front part of a motor vehicle comprising a steering column 8 and a trim shell 9 according to one embodiment of the invention.
La coquille d’habillage 9 comporte une coquille d’habillage inférieure 10 et une coquille d’habillage supérieure 11. Considérant l’axe Z, la coquille d’habillage inférieure 10 est disposée en bas et la coquille d’habillage supérieure 11 est disposée en haut de l’axe.The trim shell 9 comprises a lower trim shell 10 and an upper trim shell 11. Considering the Z axis, the lower trim shell 10 is disposed at the bottom and the upper trim shell 11 is disposed at the top of the axis.
D’une part, la coquille d’habillage inférieure 10 s’étend le long de la colonne de direction 8 et est destinée à être disposée en vis-à-vis des genoux d’un conducteur installé en position de conduite. Elle est disposée dans une zone sous le volant, en regard du siège conducteur (non représentés).On the one hand, the lower trim shell 10 extends along the steering column 8 and is intended to be arranged opposite the knees of a driver installed in the driving position. It is arranged in an area under the steering wheel, facing the driver's seat (not shown).
D’autre part, la coquille d’habillage supérieure 11 est disposée de façon à être diamétralement opposée à la coquille d’habillage supérieure 11 par rapport à la colonne de direction 8.On the other hand, the upper trim shell 11 is arranged so as to be diametrically opposite to the upper trim shell 11 with respect to the steering column 8.
La coquille d’habillage inférieure 10 comprend un moyen de protection des genoux du conducteur en cas de choc des genoux du conducteur avec la coquille d’habillage.The lower trim shell 10 includes means for protecting the driver's knees in the event of impact of the driver's knees with the trim shell.
En outre, le moyen de protection des genoux du conducteur et la coquille d’habillage inférieure sont configurés de sorte qu’ils forment une seule pièce 10. Le moyen de protection des genoux fait ainsi partie intégrante de la coquille d’habillage inférieure 10.In addition, the driver's knee protection means and the lower trim shell are configured so that they form a single piece 10. The knee protection means thus forms an integral part of the lower trim shell 10.
De préférence, la coquille d’habillage inférieure 10 est formée au moins en partie de matériau polymère expansé formant un moyen de protection efficace des genoux du conducteur en cas de choc des genoux avec la coquille d’habillage voire avec la colonne de direction en cas de choc particulièrement violent.Preferably, the lower covering shell 10 is formed at least in part of expanded polymer material forming an effective means of protecting the driver's knees in the event of an impact of the knees with the covering shell or even with the steering column in the event of particularly violent shock.
De préférence, on choisira le polypropylène expansé (EPP) particulièrement adapté pour l’absorption des chocs.Preferably, expanded polypropylene (EPP), which is particularly suitable for shock absorption, will be chosen.
Dans l’exemple illustré sur la figure 2, le moyen de protection des genoux du conducteur et la coquille d’habillage inférieure sont formés d’un même matériau de sorte qu’ils forment une structure unique monobloc 10. En d’autres termes, le moyen de protection et la coquille d’habillage inférieure sont confondus. La structure même de la coquille d’habillage inférieure 10 joue ainsi un rôle de protection des genoux du conducteur.In the example illustrated in FIG. 2, the driver's knee protection means and the lower trim shell are formed from the same material so that they form a single one-piece structure 10. In other words, the means of protection and the lower covering shell are merged. The very structure of the lower trim shell 10 thus plays a role in protecting the driver's knees.
Selon cet exemple, la coquille d’habillage inférieure 10 est entièrement formée en polypropylène expansé EPP.According to this example, the lower covering shell 10 is entirely formed of expanded polypropylene EPP.
Le matériau polypropylène expansé permet d’obtenir une coquille d’habillage inférieure 10 suffisamment rigide pour former une pièce ayant à la fois une tenue aux chocs importante et une fonction structurante de la coquille d’habillage 9.The expanded polypropylene material makes it possible to obtain a lower covering shell 10 that is sufficiently rigid to form a part having both high impact resistance and a structuring function of the covering shell 9.
Bien entendu, on pourra prévoir que la coquille d’habillage inférieure 10 soit configurée pour recevoir un ou plusieurs inserts 12, 13 destinés à structurer la coquille d’habillage 9.Of course, provision could be made for the lower covering shell 10 to be configured to receive one or more inserts 12, 13 intended to structure the covering shell 9.
Un revêtement peut être disposé sur la surface extérieure 15 de la coquille d’habillage inférieure 10 destinée à être disposée en vis-à-vis des genoux du conducteur afin de participer à l’aspect extérieur de la coquille d’habillage inférieure 10 et son intégrité.A coating may be placed on the outer surface 15 of the lower trim shell 10 intended to be placed facing the driver's knees in order to participate in the external appearance of the lower trim shell 10 and its integrity.
Par exemple, le revêtement peut être choisi parmi les matériaux suivants : du cuir, du textile ou du polychlorure de vinyle.For example, the coating can be chosen from the following materials: leather, textile or polyvinyl chloride.
La coquille d’habillage inférieure 10 est avantageusement formée par moulage, et notamment dans l’exemple illustré, par moulage de polypropylène expansé.The lower covering shell 10 is advantageously formed by molding, and in particular in the example illustrated, by molding expanded polypropylene.
