Abstract
L'invention concerne un couvercle d'obturation pour la tubulure de remplissage d'un réservoir de carburant pour véhicules automobiles, le corps de ce couvercle étant pourvu d'une saillie de prise, la saillie faisant en sorte que, en cas d'accident et lors d'une percussion de cette saillie de prise contre une partie de la carrosserie, une obturation correcte de la tubulure de remplissage reste maintenue. Pour obtenir ce résultat, la saillie de prise (36) est séparable du corps de couvercle (10) sous l'action de forces produites lors d'un accident.The invention relates to a sealing cover for the filler neck of a fuel tank for motor vehicles, the body of this cover being provided with an engaging projection, the projection ensuring that, in the event of an accident and during a percussion of this engagement projection against a part of the bodywork, correct sealing of the filler pipe remains maintained. To achieve this result, the engagement projection (36) is separable from the cover body (10) under the action of forces produced during an accident.
Description
La présente invention concerne un couvercle d'obturation pour la tubulureThe present invention relates to a closure cover for the tubing

La partie de paroi de carrosserie comportant l'ouverture constitue alors généralement le fond d'un alvéole pouvant être fermé au moyen d'un volet et recevant The body wall portion having the opening then generally constitutes the bottom of a cell that can be closed by means of a flap and receiving

Lors de déformations de la carrosserie causées par un accident et se produisant dans une zone de paroi de la carrosserie qui comporte l'ouverture ou alvéole, il peut se produire une déformation de cette zone de paroi, au cours de laquelle le bord périphérique de l'ouverture s'applique contre la saillie de prise du couvercle dl obturation et arrache celui-ci de la partie extrême de la tubulure de remplissage ou bien le pousse dans une position inclinée de sorte que l'ouverture When body deformations caused by an accident occur in a wall area of the bodywork which has the opening or socket, deformation of the wall area may occur, during which the peripheral edge of the body The opening is applied against the catching projection of the closure cover and pulls it from the end portion of the filler neck or pushes it into an inclined position so that the opening
de la tubulure est partiellement dégagée. the tubing is partially disengaged.
En outre, un accident peut produire, le cas échéant en addition à une déformation correspondante de la zone de paroi comportant l'ouverture, un décalage du réservoir de carburant dans la carrosserie qui est tel que sa tubulure de remplissage dépasse au moins In addition, an accident may produce, if necessary in addition to a corresponding deformation of the wall area having the opening, a shift of the fuel tank in the body which is such that its filler neck exceeds at least

ment la saillie de prise du couvercle d'obturation vient également buter contre le bord périphérique de l'ouverture de paroi, avec les conséquences précisées ci-dessus. L'invention a pour but de concevoir un couvercle d'obturation du type défini ci-dessus, qui assure une obturation correcte de la tubulure également dans le cas d'une percussion de sa saillie de prise contre une the protrusion of the closure cover also abuts against the peripheral edge of the wall opening, with the consequences specified above. The invention aims to design a closure cover of the type defined above, which ensures a correct closure of the tubing also in the case of a percussion of its engagement projection against a

Ce problème est résolu conformément à l'inven- tio en ce que la saillie de prise est séparable du corps de couvercle sous l'action de forces produites lors This problem is solved according to the invention in that the catch protrusion is separable from the lid body under the action of forces produced during

Selon d'autres caractéristiques du couvercle d'obturation conforme à l'invention: La saillie de prise peut être arrachée du corps de couvercle. La saillie de prise fait partie d'un chapeau distinct monté sans possibilité de rotation relative sur le corps According to other characteristics of the closure cover according to the invention: The engagement projection can be torn from the cover body. The protrusion is part of a separate cap mounted without the possibility of relative rotation on the body

Le chapeau 22 a également une forme de coupelle inversée et son bord de coupelle 24 s'accroche sur le bord de coupelle 26 du corps de couvercle 10 Au moyen d'ergots d'arrêt 28, la paroi de coupelle 24 du chapeau 22 s'accroche en arrière du bord frontal 30 de la paroi 26 du corps de couvercle, ce qui assure le blocage axial The cap 22 also has an inverted cup shape and its cup edge 24 hooks onto the cup edge 26 of the lid body 10. By means of locking pins 28, the cup wall 24 of the cap 22 is hooks behind the front edge 30 of the wall 26 of the cover body, which ensures the axial locking

Lorsque des forces exercées en cas d'accident agissent sur la saillie de prise 36 quand la tubulure de remplissage est fermée, on est assuré que cette saillie soit arrachée du fond 34 du chapeau 22 notamment grâce à la prévision de la zone de rupture imposée 38 en forme de rainure annulaire, de sorte que le corps de couvercle , y compris la partie du chapeau 22 qui reste sur lui, conserve la position d'obturation sur la tubulure When the forces exerted in the event of an accident act on the engagement protrusion 36 when the filler neck is closed, it is ensured that this protrusion is torn off the bottom 34 of the cap 22, in particular by virtue of the prediction of the imposed rupture zone 38 in the form of an annular groove, so that the lid body, including the part of the cap 22 which remains on it, keeps the closed position on the tubing
