Abstract

The arrangement has a protective cell protecting a sheath (30) against crushing during frontal impact. A cable part is slidably mounted inside the sheath and is extended between a front transversal wall (24) of a technical front face (16) and a rear transversal wall (26) of a radiator (22) of a motor vehicle. The cell is formed of ribs (32) that are extended on both sides of the sheath to form an incompressible zone during frontal impact. The ribs are carried by the front transversal wall of the technical front face.

Description

'ENCEMENT D'UN CJ DE EHICULE AUTOMO L'invention concerne un agencement à l'intérieur d'un véhicule automobile 'un câble de commande d'ouverture d'un capot, dans lequel une partie dudit i )le, montée coulissante à l'intérieur d'une gaine, s'étend entre une paroi transversale avant d'une face avant technique et une paroi transversale d'un radiateur du véhicule. Dans un véhicule automobile, l'ouverture de capot s'effectue par in iàdiaire d'une commande située dans l'habitacle, Ladite commande est rt à une Io serrure fixée sur --te face avant -nique du véhicule, sous un bord capot par l'inters liaire d'un cât .. dont le trajet sous le capot est iné par des contra : d'architecture. The invention relates to an arrangement within a motor vehicle of a hood opening control cable, in which a portion of said motor, which is slidably mounted to a motor vehicle, is Inside a sheath, extends between a transverse wall before a technical front and a transverse wall of a radiator of the vehicle. In a motor vehicle, the hood opening is effected by means of a control located in the passenger compartment, said control is rt to a lock Io fixed on -the front -nique vehicle, under a bonnet edge through the inter-liar of a cate .. whose path under the hood is iné by contra: architecture.

Ainsi da trtains véhicules, le câble présente une portion passant entre la face ave ;hnique et le radiateur, ce qui pose des difficultés import 1 15 cas de el lue. En effet, la portion de câble située entre le radiateur et 1 avant technique est montée coulissante dans une gaine. Or, lors d'un choc frontal, même à faible vitesse (ce qui est le cas d'un choc dit Danner à 16km/h), le radiateur recule en direction de la face avant technique. La gaine du câble risque donc d'être écrasée par des parties saillantes du radiateur, 20 entrainant alors une immobilisation du câble à l'intérieur de la gaine. La commande d'ouverture risque ainsi d'être fortement endommagée, ce qui est très gênant en raison de la perte de la fonctionnalité que cela représente, mais aussi en raison des coûts de réparation engendrés par le remplacement du câble complet. 25 Cependant, les essais en chocs étant se .ffectués ssez tardivement dans le développement du véhicule, il n'e alors pas risesible de modifier l'architecture du véhicule lorsqu'un tel problème est constaté. Afin de pallier ces inconvénients, l'invention a pour objet un agencement d'un câble de commande d'ouverture de capot simple, peu onéreux et ne 30 nécessitant pas de modifi de l'architecture du véhicule. Thus in some vehicles, the cable has a portion passing between the avehique face and the radiator, which poses difficulties import ell case. Indeed, the cable portion between the radiator and 1 front technical is slidably mounted in a sheath. However, during a frontal impact, even at low speed (which is the case of a Danner shock at 16km / h), the radiator moves back towards the technical front. The cable sheath may therefore be crushed by protruding parts of the radiator, thus causing the cable to become immobilized inside the sheath. The opening command is likely to be heavily damaged, which is very troublesome because of the loss of functionality that this represents, but also because of the repair costs incurred by the replacement of the complete cable. However, as the impact tests are performed late in the development of the vehicle, it is not feasible to modify the vehicle architecture when such a problem is found. In order to overcome these drawbacks, the object of the invention is an arrangement of a simple hood opening control cable, inexpensive and requiring no modification of the vehicle architecture.

Tel que représenté à la figure 1, un véhicule automobile comporte une commande d'ouverture 10 d'un capot 12. Ladite corn Inde 10 est reliée, par l'intermédiaire d'un câble 20, à une serrure 14 par une face avant technique 16 du véhicule et située sous un bord avant -a capot 12. En avant de la face avant technique 16, le véhicule comporte ég un radiateur 22. Io Tel que représenté aux figures 2 et 3, avant de parvenir à la serrure 14, le câble 20 passe entre une paroi - ns ersale avant 24 de la face avant ti inique 16 et une paroi transveu. 26 du radis ..i 22. Les parois 2 ' et 26 sont d'orientation vertical La portion 28 de câble 20 passant entre les deux parois 24 et 26 est munie 15 d'une gaine 30i Le ie 20 est monté coulissant à L, H Ir de ladite gaine 30, permettant ainsi l'ouverture du capot 12 lorsque la commande 10 est actionnée. Au moins deux nervures 32, sont prévues sur ln paroi avant 24 de la face avant ehnique 16. Les nervures 32 s'étende' . une direction sensiblement ,ndiculaire à la paroi avant 24 et sont disposées en regard de la portion 28 20 able 20, de façon qu'elle soient situées de part et d'autre de la geine 30. La gaine 30 est ainsi apte à venir se loger entre .iervures 32. artement entre les nervures 32 est donc au moins égal au nètre de la ge En outre, entre les nervures 32, une cavité 34, apte à Heillir la gaine 30, est ménagée dans la paroi avant 24 de la face avant techniqt 16. 25 Ainsi la somme de la hauteur h des nervures 32 et de la profondeur p de la cavité 34 est au moins égale au diamètre de la gaine 30. Les nervures 32 forment des zones incompressibles en cas de choc. Ainsi, lorsque le radiateur 22 recule en direction de la face avant technique 16 sous l'effet d'un effort dû à un choc, la paroi arrière 26 du radiateur 22 entre en 30 contact avec les nervures 32 et non pas directement avec la paroi avant 24 de la face avant technique 16. De ce fait, la gaine 30, en étant logée entre les - - s 32 et dans la ce 34 est ainsi pr- d'u intuel écr lent lors d'un choc.

By the transverse wall before the front technical front, said ribs extending on either side of the gains, thong to form an incomprehensible area in case of impact. the spindle is formed in the front wall of the airstream, so that the protective cell is able to catch the sheath in the event of an impact, the ribs and the cavity are made of material With the front wall of the front face, the ribs and the cavity are formed by a chute attached to the outer wall, which is at least equal to the diameter of the sheath. The sum of the height r ', s and the depth of the cavity is at least equal to the diameter e the sheath.' Ure a 'vehicle, in comma. in which: - Figure 1 is a general view of a front part of a motor vehicle - Figure 2 is a sectional view along a longitudinal plane P of the detail D of Figure 1. - Figure 3 is a view according to a plant 'al of the det d Figure 2. 20 d'aut characteristics and front of the apparal invention' 'the descript of examples In the description which follows, we give a non-limiting longitudinal, vertical and transverse distribution of the trihedron L, V, T di ds 1 to 3. As shown in FIG. motor vehicle comprises an opening control 10 of a hood 12. Said corn India 10 is connected, via a cable 20, to a lock 14 by a front end 16 of the vehicle and located under a front edge -a hood 12. In front of the technical front panel 16, the vehicle includes a radiator 22. Io As shown in Figures 2 and 3, before reaching the lock 14, the cable 20 passes between a wall - ns ersale before 24 of the front face ti inique 16 and a transveu wall. 22. The walls 2 'and 26 are of vertical orientation The portion 28 of cable 20 passing between the two walls 24 and 26 is provided with a sheath 30i, ie 20 is slidably mounted at L, H Ir of said sheath 30, allowing the opening of the cover 12 when the control 10 is actuated. At least two ribs 32 are provided on the front wall 24 of the ethnic front face 16. The ribs 32 extend. a direction substantially ndicular to the front wall 24 and are arranged opposite the portion 28 able 20 20, so that it is located on either side of the groin 30. The sheath 30 is thus able to come to It is therefore at least equal to the geometry of the ge 32 between the ribs 32. A cavity 34, capable of sheathing the sheath 30, is formed in the front wall 24 of the face. Thus, the sum of the height h of the ribs 32 and the depth p of the cavity 34 is at least equal to the diameter of the sheath 30. The ribs 32 form incompressible zones in the event of impact. Thus, when the radiator 22 moves back towards the technical front face 16 under the effect of a force due to an impact, the rear wall 26 of the radiator 22 comes into contact with the ribs 32 and not directly with the wall. Thus, the sheath 30, being housed between the ss 32 and in the sce 34, is thus intui gally blank during an impact.
