On a illustré sur la figure 1 un système de sécurité 10 de véhicule automobile comportant une poignée d'ouvrant de véhicule automobile.FIG. 1 illustrates a security system 10 of a motor vehicle comprising a handle of an opening motor vehicle.

La poignée comporte un support de poignée 14 qui est destiné à être fixé sur un panneau externe de carrosserie 12 de l'ouvrant, plus particulièrement sur une face interne de celui-ci. Un levier de préhension 16 est destiné à être monté du côté extérieur de ce panneau 12 en étant articulé sur le support 14 par une extrémité longitudinale avant 18, autour d'un axe A1.The handle has a handle support 14 which is intended to be fixed to an external body panel 12 of the opening, more particularly on an internal face of this one. A gripping lever 16 is intended to be mounted on the outside of this panel 12 while being articulated on the support 14 by a front longitudinal end 18, around an axis A1.

Pour ce faire, l'extrémité avant 18 du levier 16, qui se présente sensiblement sous la forme d'une barre d'orientation longitudinale, comporte un timon 20 destiné à être engagé au travers d'un orifice avant 22 du panneau de carrosserie 12, afin d'être monté à rotation sur le support 14. To do this, the front end 18 of the lever 16, which is substantially in the form of an orientation bar longitudinal, includes a drawbar 20 intended to be engaged at through a front orifice 22 of the body panel 12, in order to be rotatably mounted on the support 14.

L'extrémité arrière 24 du levier de préhension 16 comporte un pied arrière 26 qui s'étend transversalement vers l'intérieur au travers d'un orifice arrière 28 aménagé dans le panneau 12 de manière à coopérer avec une tringlerie dont on a représenté sur la figure 1 un renvoi 30.The rear end 24 of the gripping lever 16 has a rear leg 26 which extends transversely towards the interior through a rear orifice 28 arranged in the panel 12 so as to cooperate with a linkage which has shown in Figure 1 a reference 30.

Un utilisateur est ainsi susceptible de manoeuvrer le levier de préhension en saisissant une partie sensiblement centrale du levier 16 et en le tirant transversalement vers l'extérieur depuis une position de repos jusqu'à une position d'ouverture. Lors de ce mouvement de rotation autour de l'axe A1 du levier 16, le pied arrière 26 est destiné à provoquer une rotation d'axe A2 du renvoi 30 entre une position de repos et une position d'ouverture, positions qui correspondent à celles du levier de préhension 16.A user is thus likely to manipulate the grip lever by grasping a part substantially central lever 16 and pulling it transversely towards outside from a rest position to a position opening hours. During this rotational movement around the axis A1 of the lever 16, the rear foot 26 is intended to cause a axis rotation A2 of the reference 30 between a rest position and an open position, positions which correspond to those gripping lever 16.

Le renvoi 30 permet par exemple de commander l'ouverture d'une serrure, par l'intermédiaire d'un câble (non représenté).The reference 30 allows for example to order the opening of a lock, via a cable (not represented).

Pour amener le levier de préhension vers sa position d'ouverture, l'utilisateur du véhicule doit donc introduire sa main entre le panneau de carrosserie 12 et une surface de préhension 32 du levier 16 pour pouvoir tirer ce dernier vers lui, vers l'extérieur par rapport au panneau 12. Pour ce faire, il est prévu entre le panneau 12 et le levier 16 un espace 34 qui, dans un plan perpendiculaire à l'axe A1, est délimité transversalement par un renfoncement vers l'intérieur 36 du panneau 12 et par la surface de préhension 32 du levier 16 qui sont en vis-à-vis l'un de l'autre.To bring the gripping lever to its position vehicle user must therefore enter their hand between the body panel 12 and a surface of grip 32 of lever 16 in order to be able to pull the latter towards him, outwards with respect to the panel 12. To do this, he is provided between the panel 12 and the lever 16 a space 34 which, in a plane perpendicular to the axis A1, is delimited transversely by an inward recess 36 of the panel 12 and by the gripping surface 32 of the lever 16 which are facing each other.

Conformément aux enseignements de l'invention, le système de sécurité comporte des moyens de détection qui permettent de détecter la présence de la main de l'utilisateur dans l'espace 34 avant que celui-ci n'ait effectivement saisi le levier 16 par sa surface de préhension 32, et qui sont portés par le support de poignée 14 agencé du côté de la face interne du panneau 12.In accordance with the teachings of the invention, the security system includes detection means which detect the presence of the user's hand in space 34 before he actually entered the lever 16 by its gripping surface 32, and which are carried by the handle support 14 arranged on the side of the internal face from panel 12.

Plus particulièrement, et comme on peut le voir sur les figures 2 et 3, les moyens de détection comportent notamment un émetteur 38 et un récepteur 40 qui sont portés par un boítier 42 lui-même fixé sur le support de poignée 14. L'émetteur 38 et le récepteur 40 sont tous les deux reliés à un module électronique de commande 44 qui est agencé à l'intérieur du boítier 42.More particularly, and as we can see on the Figures 2 and 3, the detection means include in particular a transmitter 38 and a receiver 40 which are carried by a case 42 itself fixed on the handle support 14. Both transmitter 38 and receiver 40 are connected to a electronic control module 44 which is arranged at inside the housing 42.

Dans l'exemple de réalisation illustré, l'émetteur 38 émet un signal de type électromagnétique qui est destiné à être reçu par le récepteur 40. Le signal est émis de manière à effectuer une trajectoire qui s'étend au travers de l'espace 34 de telle manière que, lorsque la main de l'utilisateur pénètre à l'intérieur de cet espace 34, elle s'interpose obligatoirement dans la trajectoire du signal si bien que la transmission du signal entre l'émetteur et le récepteur se trouve coupée. Le récepteur 40 ne recevant plus de signal, il en sera déduit une information relative à la présence de la main dans cet espace 34.In the illustrated embodiment, the transmitter 38 emits an electromagnetic type signal which is intended for be received by the receiver 40. The signal is transmitted so as to make a trajectory that extends through space 34 in such a way that when the user's hand enters inside this space 34, it must interpose in the signal path so that the transmission of the signal between the transmitter and the receiver is cut off. The receiver 40 no longer receiving a signal, this will result in a information relating to the presence of the hand in this space 34.

Le signal émis par l'émetteur 38 est par exemple un signal lumineux dans le domaine infrarouge. Dans l'exemple illustré, l'émetteur 38 et le récepteur 40 sont agencés sensiblement côte à côte en retrait vers l'intérieur par rapport au panneau de carrosserie. Ils sont agencés en regard d'une fenêtre 46 qui est découpée dans le renfoncement 36 du panneau de carrosserie 12. Dans l'exemple de réalisation illustré, l'émetteur et le récepteur sont agencés en regard de la même fenêtre 46. Le signal émis par l'émetteur 38 est donc dirigé vers l'extérieur au travers de la fenêtre 46 du panneau 12 et il est prévu un réflecteur 48 qui est porté par le levier 16 et qui renvoie le signal en direction du récepteur 40, de nouveau au travers de la fenêtre 46.The signal emitted by the transmitter 38 is for example a light signal in the infrared range. In the example illustrated, the transmitter 38 and the receiver 40 are arranged substantially side by side set back inward from body panel. They are arranged next to a window 46 which is cut in the recess 36 of the body panel 12. In the exemplary embodiment illustrated, the transmitter and the receiver are arranged opposite the same window 46. The signal emitted by the transmitter 38 is therefore directed outward through window 46 of the panel 12 and there is provided a reflector 48 which is carried by the lever 16 and which sends the signal back to the receiver 40, again through window 46.

Conformément aux enseignements de l'invention, le boítier 42 qui regroupe les moyens de détection est destiné à être fixé sur le support 14 par simple emboítement élastique. Plus particulièrement, on voit que le support 14 comporte, du côté de sa face externe qui est en regard du panneau 12, une empreinte en creux 50 qui est sensiblement de forme complémentaire de celle du boítier 42, plus particulièrement de forme complémentaire de celle d'un corps principal 52 du boítier 42. En l'occurrence, le corps principal 52 est sensiblement parallélépipédique.In accordance with the teachings of the invention, the box 42 which groups together the detection means is intended for be fixed on the support 14 by simple elastic fitting. More particularly, it can be seen that the support 14 includes, side of its external face which is opposite panel 12, a hollow imprint 50 which is substantially of complementary shape of that of the housing 42, more particularly in shape complementary to that of a main body 52 of the housing 42. In this case, the main body 52 is substantially parallelepiped.

Comme on peut le voir sur les figures 2 et 3, le boítier 42 est susceptible d'être engagé transversalement de l'extérieur vers l'intérieur dans l'empreinte 50 et il comporte des pions de positionnement 54 qui s'étendent transversalement vers l'intérieur depuis une face interne 56 et qui sont destinés à être reçus dans des orifices correspondants 58 aménagés dans la face externe 60 du support de poignée 14 qui forme en l'occurrence le fond de l'empreinte 50.As can be seen in Figures 2 and 3, the housing 42 is likely to be engaged transversely from outside to inside in footprint 50 and it has positioning pins 54 which extend transversely inwards from an internal face 56 and which are intended to be received in orifices correspondents 58 arranged in the external face 60 of the handle support 14 which in this case forms the bottom of footprint 50.

Les deux pions de positionnement 54 permettent donc d'assurer une grande précision de la position relative entre d'une part le boítier 42, qui porte l'émetteur 38 et le récepteur 40, et d'autre part le support de poignée 14.The two positioning pins 54 therefore allow ensure high accuracy of the relative position between on the one hand the housing 42, which carries the transmitter 38 and the receiver 40, and on the other hand the handle support 14.

Pour la fixation du boítier 42 sur le support 14, il est prévu deux pattes élastiques 61 qui s'étendent transversalement vers l'extérieur depuis le fond de l'empreinte 50 et dont l'extrémité libre en forme de crochet est destinée à coopérer avec des ergots d'accrochage 62 aménagés sur des faces latérales du corps principal du boítier 42. For fixing the housing 42 on the support 14, it is provided with two elastic legs 61 which extend transversely outward from the bottom of the footprint 50 and whose free end in the form of a hook is intended to cooperate with latching lugs 62 arranged on side faces of the main body of the housing 42.

Ainsi, la fixation du boítier 42 sur le support 14 est réalisée par simple emboítement élastique ou encliquetage.Thus, the fixing of the housing 42 on the support 14 is made by simple elastic fitting or snap-fastening.

Le boítier 42 comporte, en plus du corps principal 52, un corps de connecteur 64. Le corps de connecteur renferme des broches de connexion par lesquelles le circuit de commande 44 des moyens de détection est destiné à être relié d'une part une alimentation électrique et, d'autre part, à une centrale d'antivol (non représentée).The housing 42 comprises, in addition to the main body 52, a connector body 64. The connector body contains connection pins through which the circuit control 44 of the detection means is intended to be connected on the one hand a power supply and, on the other hand, to a anti-theft control unit (not shown).

Avantageusement, le corps principal 52 et le corps de connecteur 64 sont réalisés venus de matière en une seule pièce par moulage en matière plastique. Comme on peut le voir, le corps principal 52 s'étend sensiblement selon un plan parallèle au plan du panneau de carrosserie 12 et le corps de connecteur 64 s'étend verticalement vers le bas, en étant ouvert vers le bas. Toutefois, le corps de connecteur 64 s'étend dans un plan qui est parallèle mais décalé transversalement vers l'extérieur par rapport au plan dans lequel s'étend le corps principal 52.Advantageously, the main body 52 and the body of connector 64 are made from one material plastic molding part. As we can see, the main body 52 extends substantially in a plane parallel to the plane of the body panel 12 and the body of connector 64 extends vertically downwards, being open down. However, the connector body 64 extends in a plane which is parallel but offset transversely outward from the plane in which extends the main body 52.

De la sorte, le corps de connecteur 64, qui s'étend en dehors de l'empreinte 50, présente, au niveau de sa jonction avec le corps principal 52, une épaisseur transversale réduite qui délimite une entaille longitudinale 66 ouverte transversalement vers l'intérieur. Cette entaille 66 est destinée à recevoir un élément 68 d'une paroi latérale du support 14 qui délimite l'empreinte 50.In this way, the connector body 64, which extends in outside of the imprint 50, present, at its junction with the main body 52, a reduced transverse thickness which defines a longitudinal notch 66 open transversely towards the inside. This notch 66 is intended to receive an element 68 of a side wall of the support 14 which delimits footprint 50.

Ainsi, grâce au décalage du corps de connecteur et grâce à la présence de l'entaille 66, il est possible de conserver tout autour de l'empreinte 50 une paroi latérale continue qui assure une bonne rigidité au support 14.Thus, thanks to the offset of the connector body and thanks to the presence of the notch 66, it is possible to keep a side wall all around the footprint 50 continuous which provides good rigidity to the support 14.

Par ailleurs, les moyens de détection comportent un interrupteur qui est agencé à l'intérieur du boítier 42. Cet interrupteur est destiné à être commandé par un actionneur 70 lié à la tringlerie d'ouverture de la serrure. En effet, un tel interrupteur peut par exemple être utilisé pour suppléer à une éventuelle défaillance du système de détection à distance par signal électromagnétique.Furthermore, the detection means include a switch which is arranged inside the housing 42. This switch is intended to be controlled by an actuator 70 linked to the opening linkage of the lock. Indeed, such switch can for example be used to supplement a possible failure of the remote detection system by electromagnetic signal.

Dans l'exemple illustré, on peut voir que l'actionneur 70 est un actionneur basculant articulé autour du même axe A2 que le renvoi 30 de la tringlerie. Lorsque le renvoi 30 est en position de repos, il force l'actionneur 70 vers une position inactive, à l'encontre de moyens de rappel élastique 72. Dès que le renvoi 30 quitte sa position de repos, les moyens élastiques 72 peuvent solliciter l'actionneur 70 en rotation autour de l'axe A2 vers une position active dans laquelle un doigt d'actionnement 74 de l'actionneur 70, qui s'étend du côté intérieur du support 14, se déplace transversalement vers l'extérieur.In the example illustrated, it can be seen that the actuator 70 is a tilting actuator articulated around the same axis A2 as reference 30 of the linkage. When the reference 30 is in rest position, it forces the actuator 70 to a position inactive, against elastic return means 72. From that the reference 30 leaves its rest position, the means elastic 72 can act on the actuator 70 in rotation around the A2 axis towards an active position in which a actuating finger 74 of the actuator 70, which extends from the side inside of the support 14, moves transversely towards outside.

Selon l'invention, l'interrupteur est agencé dans le boítier de manière à être situé juste en regard d'une fenêtre aménagée dans la face interne 56 du boítier 42, laquelle se situe en regard d'une fenêtre 76 correspondante aménagée dans la face interne 60 du support 14 qui forme le fond de l'empreinte 50. Avantageusement, la fenêtre du boítier 42 est fermée de manière étanche par une membrane souple 78.According to the invention, the switch is arranged in the case so as to be located right next to a window fitted in the internal face 56 of the housing 42, which is located next to a corresponding fitted window 76 in the internal face 60 of the support 14 which forms the bottom of the imprint 50. Advantageously, the window of the housing 42 is tightly closed by a flexible membrane 78.

De la sorte, le doigt d'actionnement 74 est susceptible de pénétrer transversalement de l'intérieur vers l'extérieur au travers de la fenêtre 76 du support 14 pour déformer la membrane 78 et pour actionneur l'interrupteur agencé dans le boítier 42.In this way, the actuating finger 74 is susceptible to penetrate transversely from the inside to the outside at through the window 76 of the support 14 to deform the diaphragm 78 and for actuator the switch arranged in the housing 42.

Par ailleurs, on peut voir sur les figures que l'émetteur 38 et le récepteur 40 sont agencés en regard d'une fenêtre 47 qui est aménagée dans une face externe du corps principal 52 du boítier 42 et qui correspond à la fenêtre 46 du panneau de carrosserie 12 de telle sorte que les deux capteurs puissent "observer" l'espace 34. Autour de la fenêtre 47, il est prévu une paroi tubulaire 49 qui s'étend axialement vers l'extérieur en direction du panneau 12, sans atteindre ce dernier.Furthermore, we can see in the figures that the transmitter 38 and the receiver 40 are arranged opposite a window 47 which is arranged in an external face of the main body 52 of the housing 42 and which corresponds to the window 46 of the panel body 12 so that the two sensors can "observe" space 34. Around window 47, there is provision a tubular wall 49 which extends axially outwards towards panel 12, without reaching the latter.

Dans l'exemple illustré, la fenêtre 46 du panneau de carrosserie 12 est destinée à être obturée par un cache 80 dont une paroi transversale externe 82 s'étend sensiblement parallèlement au panneau de carrosserie 12, du côté externe de celui-ci. Bien entendu, la paroi transversale externe 82 du cache 80 est réalisée en un matériau qui est transparent pour le signal électromagnétique.In the example illustrated, window 46 of the control panel body 12 is intended to be closed by a cover 80 an outer transverse wall 82 of which extends substantially parallel to the body panel 12, on the external side of it. Of course, the external transverse wall 82 of the cover 80 is made of a material which is transparent for the electromagnetic signal.

Le cache 80 comporte une jupe tubulaire 84 qui s'étend axialement vers l'intérieur depuis la paroi transversale externe 82, au travers de la fenêtre 38 du panneau 12. L'extrémité interne de la jupe 84 est destinée à entourer par l'extérieur la paroi tubulaire 49 du boítier 42 et il est prévu des moyens d'étanchéité interposés entre la paroi tubulaire 49 du boítier 42 et la jupe tubulaire 84 du cache 80 pour éviter que des poussières ou de l'humidité ne puissent pénétrer à l'intérieur du boítier 42.The cover 80 comprises a tubular skirt 84 which extends axially inward from the outer transverse wall 82, through window 38 of panel 12. The end internal of the skirt 84 is intended to surround from the outside the tubular wall 49 of the housing 42 and means are provided sealing interposed between the tubular wall 49 of the housing 42 and the tubular skirt 84 of the cover 80 to prevent dust or moisture cannot get inside housing 42.

Comme on peut le voir sur la figure 4, les moyens d'étanchéité peuvent par exemple être réalisés sous la forme d'un joint 86 en matériau élastomère surmoulé autour de l'extrémité externe de la paroi tubulaire 49. Ce joint 86 présente en l'occurrence trois lèvres 88 dirigées radialement vers l'extérieur, ces trois lèvres étant concentriques et décalées transversalement les unes par rapport aux autres. Ces lèvres 88 sont destinés à venir en contact avec la jupe tubulaire 84 du cache 80 pour assurer l'étanchéité.As can be seen in Figure 4, the means sealing can for example be made in the form a seal 86 of elastomeric material overmolded around the outer end of the tubular wall 49. This seal 86 in this case has three lips 88 directed radially outwards, these three lips being concentric and offset transversely with respect to each other. These lips 88 are intended to come into contact with the skirt 84 of the cover 80 for sealing.
