Description

Système de détection de position de sièges amovibles dans un véhicule. Position detection system for removable seats in a vehicle.
La présente invention concerne un système de détection de position de sièges amovibles dans un véhicule. ARRIERE PLAN DE L'INVENTIONThe present invention relates to a position detection system of removable seats in a vehicle. BACKGROUND OF THE INVENTION
On sait que pour améliorer la gestion de l'espace disponible dans un véhicule il est souhaitable que les sièges arrières soient montés de façon amovible. Pour certaines applications, notamment pour le contrôle du verrouillage des ceintures de sécurité, il est nécessaire de pouvoir détecter la position de chaque siège installé. On connaît du document US-A-5 804 887 un système de détection de position de sièges amovibles comprenant un circuit de détection implanté dans le plancher du véhicule. Le circuit de détection comporte des interrupteurs à commande magnétique à chacun des emplacements ou un siège amovible est susceptible- implanté, et chaque fauteuil est équipé d'un aimant de commande. Lorsqu'un siège est mis en place dans le véhicule, l'aimant de com- mande porté par le siège vient en regard de l'interrupteur à commande magnétique et provoque un changement d'état de celui-ci, ce qui permet de détecter la position du siège. Toutefois l'implantation du circuit dans le plancher du véhicule augmente de façon non négligeable le coût de réalisation du véhicule et le circuit est difficilement accessible, de sorte qu'en cas de défaillance, 1 ' intervention pour la remise en état du circuit est complexe .It is known that to improve the management of the available space in a vehicle it is desirable that the rear seats are mounted removably. For certain applications, in particular for the control of the locking of the safety belts, it is necessary to be able to detect the position of each installed seat. Document US-A-5 804 887 discloses a detachable seat position detection system comprising a detection circuit implanted in the floor of the vehicle. The sensing circuit has magnetically controlled switches at each of the locations where a removable seat is susceptible-implanted, and each chair is equipped with a control magnet. When a seat is placed in the vehicle, the control magnet carried by the seat faces the magnetically controlled switch and causes a change of state thereof, which makes it possible to detect the position of the seat. However, the implementation of the circuit in the floor of the vehicle significantly increases the cost of realization of the vehicle and the circuit is difficult to access, so that in case of failure, 1 intervention for the rehabilitation of the circuit is complex .
On connaît également des documents GB-A-2 383 879 et GB 2 401 467, un système de détection de position de sièges amovibles dans lequel chaque siège est équipé d'un organe de communication sans fil pour communiquer avec un organe de communication correspondant monté dans le plancher du véhicule afin de permettre une mise en communica- tion sélective d'un organe de communication porté par le siège avec l'un des organes de communication implanté dans le plancher. Comme précédemment, il est nécessaire de prévoir dans le plancher un circuit de liaison des différents organes de communication avec l'unité centrale de gestion de la position des sièges de sorte que ce système présente les mêmes inconvénients de coût de réalisation et de complexité d'intervention en cas de défaillance. En outre pour s'assurer de la détection correcte de la position du siège, ce document propose un système complexe comprenant deux organes de communication indépendants associés à chaque siège.Also known are GB-A-2 383 879 and GB 2 401 467, a detachable seat position detection system in which each seat is equipped with a wireless communication member for communicating with a corresponding communication member mounted in the floor of the vehicle to enable selective communication of a communication device carried by the vehicle. seat with one of the communication devices located in the floor. As before, it is necessary to provide in the floor a connecting circuit of the various communication members with the central unit for managing the position of the seats so that this system has the same drawbacks of cost of implementation and complexity of intervention in case of failure. In addition to ensuring the correct detection of the seat position, this document proposes a complex system comprising two independent communication members associated with each seat.
OBJET DE L'INVENTIONOBJECT OF THE INVENTION
Un but de 1 ' invention est de proposer un système de détection de position de sièges amovibles pouvant être implanté facilement dans le véhicule et sur lequel une intervention puisse être effectuée de façon simple.An object of the invention is to provide a detachable seat position detection system that can be easily implanted in the vehicle and on which an intervention can be performed in a simple manner.
BREVE DESCRIPTION DE L'INVENTIONBRIEF DESCRIPTION OF THE INVENTION
En vue de la réalisation de ce but, on propose selon l'invention un système de détection de position de sièges amovibles dans un véhicule, chaque siège étant équipé d'un organe de communication sans fil pour communiquer avec un organe de communication correspondant monté dans le véhicule, dans lequel l'organe de communication sans fil de chaque siège amovible est associé à un circuit de détection de position comprenant au moins deux interrupteurs de détection de position à commande magnétique et élabore un signal en fonction d'un état des interrupteurs de détection de position, et le véhicule est équipé d'une série d'aimants de commande disposés pour commander de façon sélective les interrupteurs de détection de position en fonction de la position de chaque siège .In order to achieve this object, the invention proposes a system for detecting the position of removable seats in a vehicle, each seat being equipped with a wireless communication element for communicating with a corresponding communication element mounted in a vehicle. the vehicle, in which the wireless communication member of each removable seat is associated with a position detection circuit comprising at least two magnetically controlled position detection switches and generates a signal according to a state of the switches of the position detection, and the vehicle is equipped with a series of control magnets arranged to selectively control the position detection switches according to the position of each seat.
Ainsi l'organe de communication sans fil de chaque siège émet un signal qui est représentatif de l'état de chacun des interrupteurs de détection de position de sorte qu'il est possible d'implanter en un point quelconque du véhicule un récepteur unique associé à une unité de traitement qui détermine la position exacte du siège en fonction du signal reçu. En outre, lorsque le siège amovible est monté sur des coulisseaux mobiles lon- gitudinalement dans des rails, il suffit de disposer les aimants de commande sur les coulisseaux pour repérer la position du siège, quel que soit l'emplacement du coulis- seau dans le rail. Par ailleurs, les sièges amovibles sont généralement équipés de deux boîtiers de verrouillage de ceinture de sécurité disposés sur chacun des côtés du siège pour permettre un verrouillage de la ceinture de sécurité sur un côté opposé à l'enrouleur de la ceinture de sécurité quelle que soit la position du siège.Thus the wireless communication member of each seat emits a signal which is representative of the state of each of the position detection switches of the seat. so that it is possible to implement at any point in the vehicle a single receiver associated with a processing unit that determines the exact position of the seat according to the received signal. In addition, when the removable seat is mounted on sliders movable longitudinally in rails, it is sufficient to arrange the control magnets on the sliders to identify the position of the seat, regardless of the location of the slider in the seat. rail. Furthermore, the removable seats are generally equipped with two seat belt lock boxes disposed on each side of the seat to allow locking of the seat belt on a side opposite to the seat belt retractor whatever the position of the seat.
Selon une version avantageuse de 1 ' invention deux interrupteurs de détection de position sont montés en série avec des détecteurs de verrouillage de ceinture de sécurité portés par chaque siège. Ainsi la détection du verrouillage de la ceinture de sécurité est effectuée en relation avec la position du siège de sorte qu'il est possible de s'assurer que la boucle de la ceinture de sécurité est bien introduite dans le boîtier de verrouillage correspondant à la position du siège. BREVE DESCRIPTION DES DESSINSAccording to an advantageous version of the invention two position detection switches are connected in series with seat belt locking sensors carried by each seat. Thus the detection of the locking of the safety belt is performed in relation to the position of the seat so that it is possible to ensure that the buckle of the safety belt is inserted into the locking housing corresponding to the position. from the headquarters.

In connection with this mode of locking of seat belts, the position detection switches 9.1, 9.2 are preferably in a closed position at rest, that is to say in the absence of magnetic control. With reference to FIG. 4, the implantation of the control magnets 15 is such that for a configuration of three contiguous seats, the control magnet 15.11 is opposite the position detection switch 9.1 of the left seat while the control magnet 15.21 is opposite the position detection switch 9.2 of the right seat and no control magnet is opposite the detection switches 9.1, 9.2 of the central seat. The position detection switch
9.1 du siège de gauche est donc en position ouverte tan- dis que l'interrupteur de détection de position 9.2 du même siège est en position fermée. Si un utilisateur introduit par erreur la bouche 3 de la ceinture de sécurité dans le boîtier de verrouillage 2 de gauche de ce siège, l'interrupteur 5 correspondant est mis dans un état fermé mais la' position ouverte de l'interrupteur de détection de position 9.1 interrompt le circuit de sorte qu'aucun signal de verrouillage effectif n'est envoyé vers le récepteur 14. Au contraire si l'occupant du siège de gauche introduit convenablement la boucle 3 dans le boîtier de verrouillage 2 de droite, les deux interrupteurs en série9.1 of the left seat is thus in the open position while the position detection switch 9.2 of the same seat is in the closed position. If a user error introduced by the mouth 3 of the seat belt 2 in the left seat of the lock housing, the switch 5 caller is put in a closed state but the open position of the position detecting switch 9.1 interrupts the circuit so that no effective locking signal is sent to the receiver 14. On the other hand, if the occupant of the left seat appropriately introduces the loop 3 into the right lock housing 2, the two switches series
9.2 et 5 sont fermés et un signal de verrouillage positif est alors envoyé vers le récepteur 14. De la même manière on constatera que compte tenu de l'état fermé des interrupteurs de détection de position 9.1 et 9.2 un signal positif de verrouillage du siège central ne sera envoyé que si les deux boîtiers de verrouillage 2 ont reçu une boucle 3. Pour le siège de droite un signal de verrouillage positif ne sera envoyé que si la boucle de sécurité est introduite dans le boîtier de verrouillage de gauche qui correspond à l'interrupteur de détection de position 9.1 dans un état fermé .9.2 and 5 are closed and a positive locking signal is then sent to the receiver 14. In the same manner it will be seen that, in view of the closed state of the position detection switches 9.1 and 9.2, a positive locking signal of the central seat will only be sent if the two lock boxes 2 have received a loop 3. For the seat on the right a positive locking signal will be sent only if the safety loop is inserted into the left lock box which corresponds to the position detection switch 9.1 in a closed state.
La figure 5 illustre une configuration de deux sièges implantés de façon centrée. Pour permettre une détection convenable de la position du siège et assurer un contrôle du verrouillage de la ceinture de sécurité correspondante, l'aimant de commande 15.12 est implanté en regard de la position prise par l'interrupteur de détection de position 9.1 du siège de gauche lorsque celui-ci est mis en place, et l'aimant de commande 15.22 est im- planté en regard de la position prise par 1 ' interrupteur de détection de position 9.2 du siège de droite lorsque celui-ci est mis en place. Le fonctionnement est alors analogue à celui qui a été décrit à propos de la figure 4. Les interrupteurs de détection de position 9.11 et 9.12 forment une première paire sur une ligne et les interrupteurs de détection de position 9.21 et 9.22 forment une seconde paire sur une ligne décalée.Figure 5 illustrates a configuration of two centrally located seats. To enable proper detection of the seat position and to control the locking of the corresponding safety belt, the control magnet 15.12 is implanted opposite the position taken by the position detection switch 9.1 of the left seat. when it is in place, and the control magnet 15.22 is implanted opposite the position taken by the position detection switch 9.2 of the right seat when it is put in place. The operation is then analogous to that described with reference to FIG. 4. The position detection switches 9.11 and 9.12 form a first pair on one line and the position detection switches 9.21 and 9.22 form a second pair on a line. offset line.
Les figures 6 à 8 illustrent un second mode de réalisation de l'invention, plus particulièrement adapté à détecter la position des sièges amovibles lorsque ceux- ci sont disposés selon deux rangs différents. Sur la figure 6 qui illustre le dispositif de détection porté par chacun des sièges amovibles, les éléments communs avec le circuit de détection 6 portent la même référence numérique. La seule différence entre le circuit de détection 6 et le circuit de détection 16 est la présence dans le circuit de détection 16 d'un troisième interrupteur de détection de position 9.3 qui dans l'état de repos, dit fermé, illustré par la figure, renvoie la tension de contrôle sur une borne 17 du microprocesseur tandis que dans l'état dit ouvert le signal de contrôle est renvoyé sur une borne 18.Figures 6 to 8 illustrate a second embodiment of the invention, more particularly adapted to detect the position of the removable seats when they are arranged in two different rows. In Figure 6 which illustrates the detection device carried by each of the removable seats, the elements common with the detection circuit 6 have the same reference numeral. The only difference between the detection circuit 6 and the detection circuit 16 is the presence in the detection circuit 16 of a third position detection switch 9.3 which, in the so-called closed state of rest, illustrated by the figure, returns the control voltage to a terminal 17 of the microprocessor while in the so-called open state the control signal is returned to a terminal 18.
Dans ce mode de réalisation du système selon l'invention, les aimants de commande 15 correspondant au premier rang de sièges amovibles sont disposés comme illustré sur la figure 3. Quelle que soit la position d'un siège dans ce rang, l'interrupteur de détection de position 9.3 reste fermé. Les aimants de commande du deuxième rang des sièges amovibles comportent d'une part des aimants de commande 15 analogues à ceux du premier rang et également une série complémentaire d'aimants de commande portant la référence générale 19 et les références particulières 19.1, 19.2, 19.3, 19.4 et 19.5. Dans le mode de réalisation illustré les interrupteurs de détection de position 9.3 sont disposés selon une ligne décalée par rapport aux lignes des interrupteurs de détection de position 9.1 et 9.2, et les aimants de commande 19.1 - 19.5 sont disposés selon une troisième ligne. Dans le cas de trois sièges accolés sur le deuxième rang de sièges amovibles comme illustrés par la figure 8, les aimants de commande 19.1, 19.3 et 19.5 sont implantés pour commander le basculement des interrupteurs de détection de position 9.3 de chacun des sièges, ce qui permet de détecter que les sièges correspondants sont les sièges du deuxième rang. De même, le aimants de commande 19.2 et 19.4 sont implantés pour venir en regard de l'interrupteur de détection de positions 9.3 de deux sièges disposés de façon centrée selon une configuration analo- gue à celle de la figure 5.In this embodiment of the system according to the invention, the control magnets 15 corresponding to the first row of removable seats are arranged as shown in Figure 3. Regardless of the position of a seat in this row, the position detection switch 9.3 remains closed. The control magnets of the second row of the removable seats comprise firstly control magnets 15 similar to those of the first row and also a complementary series of control magnets bearing the general reference 19 and the special references 19.1, 19.2, 19.3 , 19.4 and 19.5. In the illustrated embodiment, the position detection switches 9.3 are arranged in a line offset from the lines of the position detection switches 9.1 and 9.2, and the control magnets 19.1 - 19.5 are arranged in a third line. In the case of three seats contiguous to the second row of removable seats as illustrated in Figure 8, the control magnets 19.1, 19.3 and 19.5 are located to control the tilting of the position detection switches 9.3 of each of the seats, which allows to detect that the corresponding seats are the second row seats. Similarly, the control magnets 19.2 and 19.4 are located to face the position detection switch 9.3 of two seats arranged centrally in a configuration similar to that of FIG.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications. En particulier, bien que l'invention ait été décrite en relation avec des sièges pouvant être implantés sur une même rangée soit selon une configuration de trois sièges accolés soit selon une configuration de deux sièges centrés, ce qui implique l'implantation de deux pai- res d'aimants de commande 15, on peut prévoir que les sièges amovibles soient disposés selon une seule configuration. Dans ce cas, il est possible de réduire le nombre d'aimants de commande à deux seulement pour le premier rang de sièges et à deux ou trois aimants de commande supplémentaires pour le deuxième rang de sièges.Of course, the invention is not limited to the embodiments described and variants can be made without departing from the scope of the invention as defined by the claims. In particular, although the invention has been described in relation to seats that can be located on the same row or in a configuration of three seats contiguous or in a configuration of two seats centered, which involves the implementation of two countries. of control magnets 15, it can be provided that the removable seats are arranged in a single configuration. In this case, it is possible to reduce the number of control magnets to only two for the first row of seats and two or three additional control magnets for the second row of seats.
Bien qu'il ait été prévu des interrupteurs de détection de position fermés au repos, ce qui minimise le nombre d'aimants de commande nécessaires, on peut également renforcer la sécurité positive en prévoyant des in- terrupteurs de détection de positions ouverts au repos et en y associant les aimants de commande correspondants pour chaque siège mis en place, y compris le siège central.Although closed position detecting switches have been provided, which minimizes the number of control magnets required, the positive safety can also be enhanced by providing open position detecting switches. by associating the corresponding control magnets for each seat put in place, including the central seat.
Bien que le système selon l'invention ait été dé- crit en relation avec des aimants de contrôle disposés sur des lignes décalées, ce qui permet de mieux espacer les aimants de commande et d'éviter toute interférence entre les aimants, on peut placer sur la même ligne des aimants correspondants à différents interrupteurs de dé- tection de position, voire même d'utiliser les mêmes aimants de commande pour actionner différents interrupteurs de détection de position en fin de la configuration. Although the system according to the invention has been described in relation to control magnets arranged on offset lines, which makes it possible to better space the control magnets and to avoid any interference between the magnets, it is possible to place on the same line of magnets corresponding to different position detection switches, or even using the same control magnets to actuate different position detection switches at the end of the configuration.
