Description

SERRURE DE VEHICULE AUTOMOBILE  LOCK OF MOTOR VEHICLE
L'invention concerne une serrure de véhicule automobile et peut s'appliquer à une serrure d'ouvrant, tel qu'un hayon ou une porte latérale, ou de siège de véhicule automobile. The invention relates to a lock of a motor vehicle and can be applied to an opening lock, such as a tailgate or a side door, or a motor vehicle seat.
De manière connue, une telle serrure comporte une platine, en général métallique, par laquelle la serrure est appliquée contre le chant de l'ouvrant ou du siège et fixée à celui-ci et un boîtier, en général en matière plastique, renfermant l'ensemble du mécanisme de la serrure.  In known manner, such a lock comprises a plate, generally metal, by which the lock is applied against the edge of the opening or seat and fixed thereto and a housing, generally made of plastic, enclosing the set of the mechanism of the lock.
La serrure comporte un pêne rotatif destiné à coopérer avec une gâche montée en saillie sur le bâti fixe. A cet effet, le pêne présente une encoche dans laquelle s'engage la gâche lors de la fermeture de l'ouvrant ou le positionnement du siège. La serrure renferme également un cliquet rotatif destiné à retenir le pêne dans la position de fermeture dans laquelle ce dernier retient la gâche.  The lock comprises a rotary bolt intended to cooperate with a keeper mounted projecting on the fixed frame. For this purpose, the bolt has a notch in which engages the striker when closing the opening or the positioning of the seat. The lock also contains a rotating ratchet for holding the bolt in the closed position in which the latter holds the striker.
Une telle serrure est décrite dans le document de brevet EP 1 039 079 dont le but est d'améliorer la tenue dans un même plan du pêne et du cliquet.  Such a lock is described in patent document EP 1 039 079, the purpose of which is to improve the holding in the same plane of the bolt and the pawl.
Une traverse est disposée du côté du plan moyen du pêne et du cliquet où ne se trouve pas la platine et, au moyen de collets et de vis, elle entraîne l'application de la platine contre le chant du battant mobile, cette traverse formant alors un obstacle s'opposant à un décalage du plan moyen du pêne par rapport au plan moyen du cliquet.  A crossbar is disposed on the side of the mean plane of the bolt and the pawl where the plate is not located and, by means of collars and screws, it causes the application of the plate against the edge of the movable wing, this cross then forming an obstacle opposing an offset of the mean plane of the bolt relative to the mean plane of the pawl.
Par ailleurs, dans une telle serrure, il est en général disposé un tampon ou cale-gâche en matière souple, afin d'absorber toutes les fréquences en vibration lors du déplacement du véhicule. Ce tampon est disposé dans un logement du boîtier, est fixé sur la traverse et, la serrure de l'ouvrant ou du siège étant en position fermée, la gâche est pressée contre ce cale-gâche, bloquée par le pêne, avec déformation en compression du cale-gâche. Par ailleurs, il existe en général sur le boîtier une ou des nervures moulées sur le boîtier et dirigées sensiblement perpendiculairement au plan moyen du pêne. En cas de vibrations lors du déplacement du véhicule, le pêne vient en contact avec cette ou ces nervure(s) et est ainsi maintenu en place dans son plan moyen. Furthermore, in such a lock, it is generally arranged a buffer or chock-keeper made of flexible material, to absorb all frequencies in vibration during the movement of the vehicle. This buffer is disposed in a housing of the housing, is fixed to the crossbar and, the lock of the opening or the seat being in the closed position, the striker is pressed against this wedge-keeper, blocked by the bolt, with deformation in compression chock-keeper. Moreover, there is generally on the housing one or ribs molded on the housing and directed substantially perpendicular to the mean plane of the bolt. In the event of vibrations during the movement of the vehicle, the bolt comes into contact with this or these ribs and is thus held in place in its mid-plane.
Une épaisseur connue du cale-gâche, dans le sens de sa compression parallèle au plan moyen du pêne et correspondante à la distance entre sa fixation sur la traverse et le contact de la gâche en position fermée, est de l'ordre de 9,5 mm. Cependant, il s'avère qu'une telle épaisseur entraîne la nécessité d'un trop fort effort de pression lors de la fermeture de l'ouvrant ou du siège.  A known thickness of the wedge-striker, in the direction of its compression parallel to the mean plane of the bolt and corresponding to the distance between its attachment to the cross member and the contact of the striker in the closed position, is of the order of 9.5 mm. However, it turns out that such a thickness causes the need for too much pressure when closing the sash or seat.
Il peut donc être envisagé de réduire cette épaisseur, afin de diminuer cet effort de fermeture. Cependant, la gâche étant pressée dans l'encoche du pêne entre le cale-gâche et le pêne, la pression résultante sur le pêne est alors également diminuée, et ce dernier, moins tenu, a tendance à se déplacer perpendiculairement à son plan moyen et en particulier à venir cogner contre les nervures décrites plus haut, lorsque le véhicule roule.  It can therefore be envisaged to reduce this thickness, in order to reduce this closing force. However, the striker being pressed into the notch of the bolt between the striker and the bolt, the resulting pressure on the bolt is then also decreased, and the latter, less held, tends to move perpendicularly to its mean plane and in particular to come bump against the ribs described above, when the vehicle rolls.
L'invention résout ces problèmes en proposant une solution assurant tout autant l'obtention d'un effort de pression de fermeture raisonnable que la suppression du bruit occasionné suite au contact du pêne avec ces nervures, suite aux vibrations provoquées lors du déplacement du véhicule.  The invention solves these problems by proposing a solution ensuring as much the obtaining of a reasonable closing pressure force as the suppression of noise caused by contact of the bolt with these ribs, following the vibrations caused during the movement of the vehicle.
Pour ce faire, l'invention propose une serrure de véhicule automobile comportant une platine et un boîtier renfermant l'ensemble du mécanisme de la serrure comprenant un pêne rotatif destiné à coopérer avec une gâche montée en saillie sur un bâti fixe, un cliquet rotatif destiné à retenir la gâche en position de fermeture et un cale- gâche en matériau souple disposé dans un logement du boîtier, ladite gâche étant pressée entre ce cale-gâche et le pêne en position fermée de la serrure, ledit boîtier contenant également au moins une nervure dirigée sensiblement perpendiculairement au plan moyen du pêne, caractérisée en ce que ledit cale-gâche comporte au moins une extension logée à proximité de ladite nervure et d'épaisseur débordant de la hauteur de la nervure en direction du pêne, de telle sorte qu'un déplacement du pêne perpendiculaire à son plan moyen entraîne une compression de cette extension, sans contact avec ladite nervure. To do this, the invention provides a motor vehicle lock comprising a plate and a housing enclosing the entire mechanism of the lock comprising a rotary bolt intended to cooperate with a striker mounted on a fixed frame, a rotary ratchet for to retain the keeper in the closed position and a wedge of flexible material disposed in a housing of the housing, said striker being pressed between this wedge-keeper and the bolt in the closed position of the lock, said housing also containing at least one rib directed substantially perpendicular to the mean plane of the bolt, characterized in that said wedge-keeper comprises at least one extension housed near said rib and of thickness exceeding the height of the rib in the direction of the bolt, so that a displacement of the bolt perpendicular to its mean plane causes a compression of this extension, without contact with said rib.
Grâce à l'invention, les problèmes sont résolus sans ajout de pièces supplémentaires et le nombre de composant est conservé.  Thanks to the invention, the problems are solved without adding additional parts and the number of components is preserved.
Selon un mode de réalisation préféré de l'invention, ledit cale- gâche est fixé sur une traverse disposée du côté du plan moyen du pêne et du cliquet où ne se trouve pas la platine et formant obstacle à un décalage du plan moyen du pêne par rapport au plan moyen du cliquet.  According to a preferred embodiment of the invention, said chock is attached to a crosspiece disposed on the side of the mean plane of the bolt and pawl where the plate is not located and forming an obstacle to a shift of the mean plane of the bolt by relative to the average ratchet plane.
Avantageusement, ladite extension peut être disposée à proximité d'un tronçon d'extrémité formé d'un tronçon de nervure perpendiculaire à ladite nervure et de forme rectangulaire.  Advantageously, said extension may be disposed near an end section formed of a rib portion perpendicular to said rib and of rectangular shape.
Ladite extension peut également être disposée à proximité d'un tronçon d'extrémité formé d'un tronçon de nervure perpendiculaire à ladite nervure et de forme triangulaire ou incliné par rapport à ladite nervure et de forme triangulaire.  Said extension may also be disposed near an end section formed of a rib portion perpendicular to said rib and of triangular or inclined shape with respect to said rib and of triangular shape.
De préférence, l'épaisseur de l'extension déborde d'environ de 0,4 mm de la hauteur de la nervure.  Preferably, the thickness of the extension extends approximately 0.4 mm from the height of the rib.
Le cale-gâche peut comporter deux extensions symétriques par rapport à son plan central .  The chock-keeper may have two extensions symmetrical with respect to its central plane.
Avantageusement, ledit cale-gâche est en caoutchouc à base de nitrile.  Advantageously, said chock-keeper is made of nitrile rubber.

1. 1.
Dans la description qui suit, dans un but de simplification, les directions telles que « vers le haut » ou « vers le bas » sont à considérer uniquement selon l'orientation des figures, la serrure pouvant être disposée différemment sur le véhicule automobile.  In the following description, for purposes of simplification, the directions such as "upwards" or "downwards" are to be considered solely according to the orientation of the figures, the lock being able to be arranged differently on the motor vehicle.
Comme représenté sur la figure 1, une serrure de véhicule automobile destinée à un ouvrant ou un siège comporte une platine non représentée et un boîtier 1 renfermant l'ensemble du mécanisme de la serrure comprenant un pêne rotatif 2 destiné à coopérer avec une gâche 3 montée en saillie sur un bâti fixe, un cliquet rotatif 4 destiné à retenir la gâche 3 en position de fermeture et un cale-gâche 5 en matériau souple disposé dans un logement du boîtier, la gâche 3 étant pressée entre ce cale-gâche 5 et le pêne 2 en position fermée de la serrure.  As represented in FIG. 1, a lock of a motor vehicle intended for an opening or a seat comprises a not shown plate and a casing 1 enclosing the whole mechanism of the lock comprising a rotary bolt 2 intended to cooperate with a striker 3 mounted protruding on a fixed frame, a rotating pawl 4 for retaining the striker 3 in the closed position and a striker wedge 5 of flexible material disposed in a housing of the housing, the striker 3 being pressed between the striker pad 5 and the bolt 2 in the closed position of the lock.
Dans cette position fermée, la gâche 3 est plus précisément pressée dans l'encoche du pêne 2 entre le cale-gâche 5 et le pêne 2, le cale-gâche se déformant par compression. De préférence, ledit cale-gâche est en caoutchouc à base de nitrile, de préférence d'une dureté supérieure à 50 Shore A, de préférence de l'ordre de 70 Shore A. In this closed position, the striker 3 is more precisely pressed into the notch of the bolt 2 between the striker block 5 and the bolt 2, the striker being deformed by compression. Preferably, said chock-keeper is made of nitrile-based rubber, preferably of a hardness greater than 50 Shore A, preferably of the order of 70 Shore A.
La serrure comporte également une traverse 6 disposée du côté du plan moyen du pêne et du cliquet où ne se trouve pas la platine et formant obstacle à un décalage du plan moyen du pêne par rapport au plan moyen du cliquet, telle que décrite dans le document de brevet EP 1 039 079, et le cale-gâche 5 est fixé sur cette traverse 6 comme représenté sur les figure 2 et 3. Le cale-gâche comporte un orifice 5A dans lequel est introduite une branche 6A de la traverse 6.  The lock also comprises a crosspiece 6 disposed on the side of the mean plane of the bolt and the pawl where the plate is not located and forming an obstacle to an offset of the mean plane of the bolt relative to the mean plane of the pawl, as described in document Patent EP 1 039 079, and the chock-keeper 5 is fixed on this crosspiece 6 as shown in Figures 2 and 3. The wedge-keeper has an orifice 5A into which is introduced a branch 6A of the cross member 6.
Cette fixation 5A, 6A constitue la fixation du cale-gâche qui peut éventuellement être réalisée de façon différente selon la conformation de la serrure et la présente d'une traverse ou non.  This attachment 5A, 6A is the fixing of the wedge-keeper which may optionally be performed differently depending on the conformation of the lock and the present of a cross or not.
Par ailleurs, et comme visible sur la figure 4, le boîtier 1 comportant une nervure 1A dirigée sensiblement perpendiculairement au plan moyen du pêne 2. Selon l'art antérieur, cette nervure est destinée à maintenir le pêne 2 en position dans le boîtier. Plusieurs nervures de ce type peuvent être prévues.  Furthermore, and as visible in Figure 4, the housing 1 having a rib 1A directed substantially perpendicularly to the mean plane of the bolt 2. According to the prior art, this rib is intended to hold the bolt 2 in position in the housing. Several ribs of this type can be provided.
Selon l'invention, une telle nervure connue est diminuée en hauteur et le cale-gâche 5 comporte une extension 5B logée à proximité de la nervure 1A et d'épaisseur supérieure à la hauteur de cette rainure, de telle sorte qu'un déplacement du pêne 2 perpendiculairement à son plan moyen entraîne une compression de cette extension 5A, sans contact avec la nervure 1A, comme visible sur la figure 5. De préférence, l'épaisseur de l'extension 5A est supérieure de 0,4 mm de la hauteur de la nervure 1A. De façon plus générale, l'épaisseur de l'extension 5B déborde de la hauteur de la nervure 1A en direction du pêne 2, d'environ 0,4 mm.  According to the invention, such a known rib is reduced in height and the chock-keeper 5 has an extension 5B housed near the rib 1A and thicker than the height of this groove, so that a displacement of 2 bolt perpendicular to its mean plane causes a compression of this extension 5A, without contact with the rib 1A, as shown in Figure 5. Preferably, the thickness of the extension 5A is 0.4 mm higher than the height of rib 1A. More generally, the thickness of the extension 5B exceeds the height of the rib 1A towards the bolt 2, about 0.4 mm.
Comme également visible sur la figure 1, la nervure 1A est raccourcie d'environ 0,6 mm et comporte un tronçon 1B d'extrémité formé de façon inclinée tout autant à son bord en formant un tronçon de nervure triangulaire que relativement à son positionnement relatif avec la nervure 1A. L'extension 5B comporte donc un bord externe 5C également incliné correspondant à ce tronçon d'extrémité 1B. As also visible in FIG. 1, the rib 1A is shortened by approximately 0.6 mm and comprises an end section 1B formed as inclined at its edge by forming a triangular rib section relative to its relative positioning with the rib 1A. The extension 5B therefore comprises an outer edge 5C also inclined corresponding to this end section 1B.
Cependant, ce tronçon d'extrémité 1B de la nervure 1A peut être également formé de façon inclinée à son bord en formant un tronçon de nervure triangulaire et non pas relativement à son positionnement relatif avec la nervure 1A, comme visible sur les figures 4, 5 et 6 où son plan est perpendiculaire à celui de la nervure 1A. L'extension 5B comporte alors un bord externe 5C droit correspondant à ce tronçon d'extrémité 1B.  However, this end portion 1B of the rib 1A can also be formed inclined at its edge by forming a triangular rib section and not relative to its relative positioning with the rib 1A, as can be seen in FIGS. and 6 where its plane is perpendicular to that of the rib 1A. The extension 5B then has an external edge 5C right corresponding to this end section 1B.
Enfin, ce tronçon d'extrémité 1B de la nervure 1A peut ne pas être inclinée ni à son bord et ni relativement à son positionnement relatif avec la nervure 1A, et être un tronçon de nervure perpendiculaire à la nervure 1A et de forme rectangulaire. L'extension 5B comporte alors également un bord externe 5C droit correspondant à ce tronçon d'extrémité 1B.  Finally, this end portion 1B of the rib 1A may not be inclined neither at its edge nor relative to its relative positioning with the rib 1A, and may be a rib portion perpendicular to the rib 1A and of rectangular shape. The extension 5B then also comprises a right outer edge 5C corresponding to this end section 1B.
Eventuellement, une fine nervure 1C peut subsister au-dessus de l'extension 5A du cale-gâche 5, comme visible sur les figures 6 et 7, l'épaisseur de l'extension 5B étant modifiée en conséquence.  Optionally, a thin rib 1C may remain above the extension 5A of the keeper 5, as shown in Figures 6 and 7, the thickness of the extension 5B being modified accordingly.
L'épaisseur e du cale-gâche 5, dans le sens de sa compression parallèle au plan moyen du pêne 2 et correspondante à la distance entre sa fixation sur la traverse 6 et le contact de la gâche 3 en position fermée est de préférence de l'ordre de 8,7 mm.  The thickness e of the lock wedge 5, in the direction of its compression parallel to the mean plane of the bolt 2 and corresponding to the distance between its fixing on the crosspiece 6 and the contact of the keeper 3 in the closed position is preferably 1 order of 8.7 mm.
Le cale-gâche 5 peut comporter plusieurs extensions telles que l'extension 5B précédemment décrite, selon l'agencement de nervures 1A disposées sur le boîtier. En particulier, il peut présenter deux extensions symétriques par rapport à son plan central P.  The chock-keeper 5 may include several extensions such as extension 5B described above, according to the arrangement of ribs 1A disposed on the housing. In particular, it can have two extensions symmetrical with respect to its central plane P.
