Description
Dispositif de commande du feu stop dun vehicule automobile Les dispositifs de commande connus du feu stop d'un vehicule automobile sont actionnes exclusivement par la pedale de freie du vdhicule. Lorsque 1e conducteur actionne la pedale de freie, un interrupteur branch6 dans 1e circuit d'alimentation du feu stop est ferme et celui-ci s'allume. Cet interrupteur s'ouvre et 1e feu stop s'eteint aussitöt que 1e conducteur reläche la pedale de freie. Control device for the brake light of a motor vehicle The known control devices for the brake light of a motor vehicle are actuated exclusively by the brake pedal of the vehicle. When the driver actuates the brake pedal, a switch connected to the brake light supply circuit is closed and the latter lights up. This switch opens and the brake light goes out as soon as the driver releases the brake pedal.
Ainsi, dans les cri oü un conducteur prend cons- cience trop tard d'un obstacle qui se trouve sur son chemin et ne parvient plus ä freiner de fa@on ä s'arreter avant 1'obstacle, la collision qui s'ensuit a gen6ralement pour consequence d'amener 1e conducteur ä lächer sa pedale de freie, de sorte que son feu stop s'eteint. Si ce conducteur est suivi par une file de voitures, il peut en resulter une collision en chaine. Thus, in the cries where a driver becomes aware too late of an obstacle which is in his path and no longer manages to brake in such a way as to stop before the obstacle, the collision which follows has generally as a consequence of causing the driver to let go of his brake pedal, so that his brake light goes out. If this driver is followed by a line of cars, a chain collision may result.
Le but de la prdsente Invention est d'6carter 1e Ban ger dune telle collision, en creant un dispositif de com- mande du feu stop d'un vehicule automobile qui avertisse les condueteurs suivants de la premiere collision. The object of the present invention is to prevent the Ban ger from such a collision, by creating a control device for the brake light of a motor vehicle which warns the following drivers of the first collision.
Le dispositif de commande selon 1'invention est carac- teris6 en ce que 1e circuit d'alimentation du feu stop com- prend un interrupteur dont seule la fermeture est command6e par la pedale de freie, lors d'un freinage, 1'ouverture de cet interrupteur 6tant commandee par 1'accelerateur. The control device according to the invention is characterized in that the brake light supply circuit comprises a switch, the closing of which alone is controlled by the brake pedal, during braking, the opening of the this switch being controlled by the accelerator.
Grace ä ce dispositif, 1e feu stop, qui est allum6 lors d'un freinage, ne s'eteint que lorsque 1e conducteur du vehicule, apres avoir läche la pedale de freie, actionne ä nouveau 1'accelerateur. Le feu stop, qui reste ainsi allume aussi longtemps que 1e conducteur n'a pas remis 1e pied sur 1'acc616rateur, Bonne par cons6quent ä en- tendre au conducteur du vehicule suivant qu'il n'a pas cesse de freiner. Celui-ei est averti de cette fagon du Ban ger qui se pr6sente devant lui. Thanks to this device, the brake light, which is on during braking, only goes out when the driver of the vehicle, after releasing the brake pedal, activates the accelerator again. The brake light, which thus remains lit as long as the driver has not put his foot back on the accelerator, is therefore good for telling the driver of the following vehicle that he has not stopped braking. The latter is warned of this way of the Ban ger who presents himself before him.
Pour eviter que 1e feu stop ne reste allumd dans les cas oü, apres un freinage, 1e conducteur d & ide de pour- suivre sa route, mais n'a pas ä cet effet ä presser 1'acce- lerateur, par exemple parce qu'il se trouve ä une descen- te, 1'interrupteur du dispositif de commande selon 1'in- vention peut eire, dune part, connect6 en parallele avec un interrupteur electro-pneumatique ä basse pression, destin6 ä etre commande RTI ID="0001.0274" WI="21" HE="4" LX="1512" LY="1506"> exclusivement par la pedale de freie, et, d'autre part, soumis, quant ä sa fermeture, ä un interrupteur electro-pneumatique ä haute pression, qui, lui aussi, est destine ä etre commandd exelusive- ment par la pedale de freie. Dans ce cas, 1'interrupteur du dispositif de commande West actionne que Tors d'un freinage violent. Si 1e conducteur du v6hicule ne freine que legerement, ä une descente, ledit interrupteur du dispositif de commande reste ouvert et 1e feu stop s'eteint aussitöt que 1e conducteur läche la pMale de freie. En ajoutant un temporisateur Jans 1e circuit de 1'interrup- teur du dispositif de commande, il est possible de faire clignoter 1e feu stop, lorsque le conducteur du v6hicule läche la pedale de freie apres un freinage violent. To prevent the brake light from remaining on in cases where, after braking, the driver wishes to continue on his way, but does not have to press the accelerator for this purpose, for example because If it is at a descent, the switch of the control device according to the invention can be, on the one hand, connected in parallel with a low pressure electro-pneumatic switch, intended to be controlled RTI ID=" 0001.0274" WI="21" HE="4" LX="1512" LY="1506"> exclusively by the brake pedal, and, on the other hand, subject, as to its closing, to an electro-pneumatic switch high pressure, which is also intended to be controlled exclusively by the brake pedal. In this case, the switch of the West control device actuates only Tors of a violent braking. If the driver of the vehicle brakes only lightly, on a descent, said switch of the control device remains open and the brake light goes out as soon as the driver releases the brake lever. By adding a timer to the control device switch circuit, it is possible to cause the brake light to flash when the driver of the vehicle releases the brake pedal after hard braking.
Trois formes d'execution du dispositif de comman- de selon 1'invention sont represent6es sch6matiquement et ä titre d'exemple au dessin annexe, dans lequel la fig. 1 est une vue en perspective de la premiere forme d'execution ; la fig. 2 est une vue en plan, partiellement coup6e dune partie du dispositif represente ä la fig. 1 ; la fig. 3 est une vue en perspective de la deuxieme forme d'execution, et la fig. 4 est une vue en perspective de la troisieme for me d'execution. Three embodiments of the control device according to the invention are represented schematically and by way of example in the appended drawing, in which FIG. 1 is a perspective view of the first embodiment; fig. 2 is a partially sectioned plan view of part of the device shown in FIG. 1; fig. 3 is a perspective view of the second embodiment, and FIG. 4 is a perspective view of the third embodiment.
Le dispositif de commande repr6sent6 aux fig. 1 et 2 comprend un interrupteur compose d'un contact fixe 1 et d'un contact mobile 2 et branche dans 1e circuit d'ali- mentation 3 du feu stop 4 du vehicule automobile. Le contact mobile 2 de 1'interrupteur (1, 2) est port6 par la tige 5 dune ancre 6 basculant autour d'un pivot 7. Un ressort de traction 8, arme entre un tenon fixe 9 et une goupille 10, Plantee dans la tige 5 de 1'ancre 6, maintient normalement ä cette ancre 6, ou bien dans la Position repr6sentee au dessin, dans laquelle Je ressort 8 en fait appuyer la tige 5 contra une butee fixe 11, 1e contact (1,2) 6tant ouvert, ou alors dans une seconde Position, dans laquelle 1e ressort 8 fait appuyer 1e contact mobile 2 contra 1e contact fixe 1 de 1'interrupteur (1, 2) et maintient celui-ei ferne. The control device represented in FIGS. 1 and 2 comprises a switch composed of a fixed contact 1 and a movable contact 2 and branch into the first supply circuit 3 of the brake light 4 of the motor vehicle. The movable contact 2 of the switch (1, 2) is carried by the rod 5 of an anchor 6 swinging around a pivot 7. A tension spring 8, armed between a fixed stud 9 and a pin 10, planted in the rod 5 of the anchor 6, normally held at this anchor 6, or else in the position represented in the drawing, in which I spring 8 in fact press the rod 5 against a fixed stop 11, the first contact (1,2) being open , or else in a second position, in which the first spring 8 presses the first movable contact 2 against the first fixed contact 1 of the switch (1, 2) and maintains the latter closed.
La bras 12 de 1'ancre 6 est place sous 1'aetion dune came 13 et 1e bras 14 de 1'ancre 6 est place sous 1'action dune came 15, chacune des cames 13, 15 est mont6e folle sur un tourillon, 16, 17, auquel alle est reliee angu- lairement par un ressort ä boudin, 18, 19. Chacun des ressorts 18, 19 est armd entre une Partie, 20, 21, solidaire du tourillon, 16, 17, et une goupille, 22, Plantee Jans la came correspondante. Au repos, chacun des ressorts 18, 19, maintient la goupille 22, appuyde contra une goupille, 23, 24, Plantee dans 1e tourillon, 16, 17 corres- pondant. The arm 12 of the anchor 6 is placed under the aetion of a cam 13 and the first arm 14 of the anchor 6 is placed under the action of a cam 15, each of the cams 13, 15 is mounted loose on a trunnion, 16 , 17, to which it is angularly connected by a coil spring, 18, 19. Each of the springs 18, 19 is reinforced between a part, 20, 21, integral with the journal, 16, 17, and a pin, 22, Plant Jans the corresponding cam. At rest, each of the springs 18, 19, maintains the pin 22, presses against a pin, 23, 24, planted in the first journal, 16, 17 corresponding.
La tourillon 16 Porte un bras 25, qui est muni d'un Plot 26, de fagon ä tenir lieu de maneton de commande au tourillon 16. Comme an 1e voit ä la fig. 1, 1e Plot 26 est place Jans 1e chemin de la Pedale de freie 27 du vehicule pivotant autour d'un axe 28. La tourillon 17 Porte de meine un bras 29, muni d'un Plot 30, place dans 1e chemin de l'acc616rateur constitud par une p6da-- le 31 pivotant autour d'un axe 32. The trunnion 16 carries an arm 25, which is provided with a stud 26, so as to act as a control crank pin to the trunnion 16. As seen in FIG. 1, the first stud 26 is placed in the first path of the brake pedal 27 of the vehicle pivoting around an axis 28. The journal 17 carries an arm 29, fitted with a stud 30, placed in the first path of the accelerator consisting of a pedal 31 pivoting around an axis 32.
Si 1e conducteur du vehieule presse sur la pddale de freie 27 dans la Position repr6sentee ä la fig. 1, celle-ci fait toumer 1e maneton (25, 26) et 1e tourillon 16 en armant 1e ressort 18. Ce dernier entraine la came 13, qui agit sur 1e bras 12 de 1'ancre 6, et fait basculer cette demiere de fagon ä amener 1e contact mobile 2 sur 1e contact fixe 1 et ä ferner 1'interrupteur branch6 Jans 1e circuit 3. La feu stop 4 s'allume. Des que 1e contaet mobile 2 a atteint 1e contact fixe 1, 1'ancre 6 est immo- bilisee et alle retient egalement la came 13. Cela m'em- peche pas 1e tourillon 16 et son maneton de commande (25, 26) de suivre 1e deplacement imprime ä la Pedale 27, puisque la came 13 est montde folle sur 1e tourillon 16. Salon 1'amplitude du deplacement de la Pedale 27, 1e ressort 18 s'armera plus ou moins. Lorsque 1e condueteur du vehicule reläche la Pedale de freie 27, celle-ei retour- ne dans sa Position de repos et 1e ressort 18 entraine 1e tourillon 16 et son maneton (25, 26) ä la suite de cette Pedale. L'ancre 6 raste toutefois dans la nouvelle Position quelle a atteinte, dans laquelle alle est maintenue par 1e ressort B. L'ancre 6 ne reviendra contra la butde 11 qu'au moment oü RTI ID="0002.0274" WI="3" HE="4" LX="468" LY="2057"> 1e condueteur du v6hicule pesera sur 1'accelerateur 31. L'actionnement de ce dernier aura pour effet de faire tourner 1e tourillon 17 en ecartant la gou- pille 24 de la goupille 22. Cette rotation du tourillon 17 aura pour effet d'armer 1e ressort 19, d'exercer un cou- ple sur la came 15 et d'exercer une Pression sur 1e bras 14 de 1'ancre 6. Au cours de ce mouvement de retour de 1'ancre 6, 1e bras 12 de cette derniere pourra d6pla- cer la came 13 sans difficultd, car le maneton (25, 26) est entierement libre, lorsque la Pedale de freie 27 est au repos. If the driver of the vehicle presses on the brake pedal 27 in the position shown in FIG. 1, this rotates the first crank pin (25, 26) and the first journal 16 by winding the first spring 18. The latter drives the cam 13, which acts on the first arm 12 of the anchor 6, and tilts the latter to bring the movable contact 2 to the fixed contact 1 and to close the connected switch in the first circuit 3. The brake light 4 lights up. As soon as the mobile contact 2 has reached the fixed contact 1, the anchor 6 is immobilized and also retains the cam 13. follow the displacement imparted to the Pedal 27, since the cam 13 is mounted loose on the trunnion 16. According to the amplitude of the displacement of the Pedal 27, the spring 18 will arm more or less. When the driver of the vehicle releases the brake pedal 27, the latter returns to its rest position and the spring 18 drives the pin 16 and its crank pin (25, 26) following this pedal. The anchor 6 remains however in the new position which it has reached, in which it is maintained by the first spring B. The anchor 6 will only return against the goal of 11 when RTI ID="0002.0274" WI="3" HE="4" LX="468" LY="2057"> the driver of the vehicle will press on the accelerator 31. The actuation of the latter will have the effect of rotating the pin 17 by moving the pin 24 away from the pin 22. This rotation of the pin 17 will have the effect of arming the first spring 19, of exerting a torque on the cam 15 and of exerting a Pressure on the first arm 14 of the anchor 6. During this return movement of the anchor 6, the arm 12 of the latter will be able to move the cam 13 without difficulty, because the crankpin (25, 26) is entirely free, when the brake pedal 27 is at rest.
Qual que soit 1e d6placement angulaire de 1'acc616- rateur 31 autour de son axe 32, 1'ancre 6 raste immobile des quelle a atteint la butde 11, 1e seul effet de la Pedale 31 sur 1e dispositif de commande ddcrit Cant d'armer plus ou inoins 1e ressort 19. Regardless of the angular displacement of the accelerator 31 around its axis 32, the anchor 6 remains immobile from which it has reached the goal of 11, the sole effect of the pedal 31 on the described control device more or less the first spring 19.
Dans la seconde forme d'execution (fig. 3), 1e dis- positif de commande comprend une ancre 6a sembla- ble ä 1'ancre 6 de la Premiere forme d'exdcution. L'ancre 6a est egalement destin6e ä ouvrir et ferner un interrup- teur (1, 2), branche dans 1e circuit d'alimentation 3a du feu stop 4. La circuit 3a comprend en outre un tem- porisateur 33, qui a pour effet d'interrompre periodi- quement 1e circuit 3a lorsque 1'interrupteur (1, 2) est ferne et de faire par consequent clignoter 1e feu 4. Le temporisateur' 33 pourrait naturellement aussi etre sup- prim6 et 1e circuit 3a etre compose de la meine fagon que dans la Premiere forme d'exdcution. In the second embodiment (fig. 3), the control device comprises an anchor 6a similar to the anchor 6 of the first embodiment. The anchor 6a is also intended to open and close a switch (1, 2), connected to the supply circuit 3a of the brake light 4. The circuit 3a further comprises a timer 33, which has the effect to periodically interrupt the circuit 3a when the switch (1, 2) is closed and therefore cause the light 4 to flash. way than in the First form of execution.
La dispositif de commande selon la seeonde forme d'execution differe de celui de la Premiere forme d'exd- cution par las moyens qui commandent 1'ancre 6a. Dans la seconde forme d'execution, cette ancre est com- mandee par deux dlectro-aimants 34, 35, dopt las arma- tures 36, 37 sont portees par des tiges 38, 39, articulees chacune ä 1'extremite de 1'un des bras de 1'ancre 6a. Las circuits d'excitation 40, 41 des enroulements des electro-aimants 34, 35 sont alimentds en parallele par la meine batterie 42, qui alimente egalement 1e circuit du feu 4. Un mierorupteur de Passage 43, placd sous la commande la Pedale de freie 27, est branche dans 1e circuit 40 et un microrupteur similaire 44, place sous la commande de 1'accdlerateur 31, est branchd de meine dans 1e circuit 41. The control device according to the second embodiment differs from that of the First embodiment by the means which control the anchor 6a. In the second form of execution, this anchor is controlled by two electromagnets 34, 35, the armatures 36, 37 are carried by rods 38, 39, each articulated at the end of one arms of the anchor 6a. The excitation circuits 40, 41 of the windings of the electromagnets 34, 35 are supplied in parallel by the same battery 42, which also supplies the first circuit of the light 4. A passage microswitch 43, placed under the control of the brake pedal 27 is plugged into circuit 40 and a similar microswitch 44, placed under the control of accelerator 31, is also plugged into circuit 41.
La dispositif represente ä la fig. 3 fonctionne de la meine fagon que celui des fig. 1 et 2. Lorsque la pddale 27 est actionnde, 1e microrupteur 43 ferne momen- tanement 1e circuit 40 ; 1'electro-aimant 34 tire 1'armature 36, qui provoque un basculement de 1'ancre 6a. Cette derniUe raste dans sa nouvelle Position, Jans laquelle 1'interrupteur (1, 2) est ferne, jusqu'au moment oü 1e condueteur du vdhicule actionne 1'acc616rateur 31. Ce demier a pour effet d'agir sur 1e microrupteur 44, qui ferne momentanement 1e circuit d'excitation de 1'electro- aimant 35. L'armature 37 est alors attiree, ce qui fait basculer 1'ancre 6a dans sa Position de repos, en ou- vrant 1'interrupteur (1, 2). The device shown in FIG. 3 works in the same way as that of FIGS. 1 and 2. When pedal 27 is actuated, microswitch 43 momentarily closes circuit 40; electromagnet 34 pulls armature 36, which causes rocking of anchor 6a. This last raster remains in its new position, in which the switch (1, 2) is closed, until the moment when the driver of the vehicle activates the accelerator 31. The latter has the effect of acting on the microswitch 44, which momentarily closes the excitation circuit of the electromagnet 35. The armature 37 is then attracted, which tilts the anchor 6a into its rest position, by opening the switch (1, 2).
Dans la troisieme forme d'execution (fig. 4), la Pe dale de freie 27 commande las gamitures 45 des freies du v6hicule par des moyens hydrauliques. Acet effet, la Pedale 27 eommande la tige 46 du piston d'un cylin- dre hydraulique 47 qu'une tubulure 48 relie aux cylin- dres - dont un seul est repr6sente en 49 - des tam- bours de freie du v6hicule. La tubulure 48 est reliee par une Premiere derivation 50 ä un interrupteur electro- pneumatique ä basse Pression 51 et par une seconde de- rivation 52 ä un interrupteur electropneumatique ä hau te Pression 53. L'interrupteur 51 est r6gle de fagon ä se ferner des que la Pression augmente dans la tubulure 48 et la derivation 50. En d'autres termes, 1'interrupteur 51 se ferne des que la Pedale 27 aetionne las gamitures 45. Quant ä 1'interrupteur 53, il est reg16 de fagon ä ne se ferner qu'en cas de freinage violent, c'est-ä-dire quand la Pression dans la tubulure 48 et la ddrivation 52 augmente dans des proportions relativement grandes. In the third form of execution (Fig. 4), the Pe dale of freie 27 controls las gamitures 45 of the freies of the vehicle by hydraulic means. To this end, the Pedal 27 controls the rod 46 of the piston of a hydraulic cylinder 47 which a pipe 48 connects to the cylinders - of which only one is represented at 49 - of the brake drums of the vehicle. Tubing 48 is connected by a first branch 50 to a low pressure electro-pneumatic switch 51 and by a second branch 52 to a high pressure electro-pneumatic switch 53. Pressure increases in tubing 48 and bypass 50. In other words, switch 51 closes as soon as Pedal 27 activates fittings 45. close only in the event of violent braking, that is to say when the pressure in the pipe 48 and the bypass 52 increases in relatively large proportions.
Comme an Je voit ä la fig. 4, 1'interrupteur 51 est branch6 dans 1e eircuit d'alimentation 3b du feu stop 4 du vehicule. As I see in fig. 4, the switch 51 is connected to the supply circuit 3b of the brake light 4 of the vehicle.
La dispositif de commande represente ä la fig. 4 comprend, comme ceux des deux premieres formes d'execution, un interrupteur (1, 2), qui est dgalement branche Jans 1e circuit 3b, en parallele avec 1'interrup- teur 51. Comme dans la seconde forme d'execution, 1e contact mobile 2 de 1'interrpteur (1, 2) est port6 par la tige dune ancre 6b, commandee par deux electro-ai-. mants 54, 55. L'interrupteur 53 est Branche dans 1e cir- cuit d'excitation 56 de 1'electro-aimant 54. Un micro- rupteur de passalte 57, place sous 1'action de 1'accelera- teur 31, est Branche dans 1e circuit d'excitation 58 de 1'zlectro-aimant 55. Un temporisateur 59 est enfin mon- te en serie avec Finterrupteur (1, 2). The control device shown in FIG. 4 comprises, like those of the first two embodiments, a switch (1, 2), which is also connected in the first circuit 3b, in parallel with the switch 51. As in the second embodiment, the first movable contact 2 of 1'interrpteur (1, 2) is carried by the rod dune anchor 6b, controlled by two electro-ai-. switches 54, 55. Switch 53 is connected to the excitation circuit 56 of the electromagnet 54. A passalte microswitch 57, placed under the action of the accelerator Connected to the excitation circuit 58 of the electromagnet 55. A timer 59 is finally mounted in series with the switch (1, 2).
Le dispositif de commande represente ä Ja fig. 4 fonctionne de la fa@on suivante Lorsque la pedale de frein 27 est actionnee pour un leger freinage, comme c'est 1e cas par exemple Jans une descente, 1'interrupteur 51 est Beul actionne par 1e cylin- dre 47. La fermeture de Finterrupteur 51 a pour effet d'allumer 1e feu stop 4. Ce dernier s'eteint des quo la pedale 27 est relächee. Si cette derniere est au contraire actionnee violemment, Pinterrupteur 53 se forme aussi, ce qui a pour effet d'exciter Nlectro-aimant 54. Celui- ci fait basculer Pancre 6b autour de son pivot 7, ce qui provoque la fermeture de Pinterrupteur (1, 2). Aussi longtemps quo 1e conducteur du vehicule garde 1e pied sur la pedale 27, Pinterrupteur 51 maintient 1e feu 4 allum6 de fa@on continue. Lorsque la pedale 27 est relä- chee, 1'interrupteur 51 s'ouvre, mais 1'interrupteur (1, 2) roste forme. Le temporisateur 59 fait par cons4uent clignoter 1e feu 4. Celui-ei ne s'eteint qu'au moment oü 1e conducteur du vehicule actionne l'accelerateur 31. Com- me dans la seconde forme d'execution, 1'accelerateur 31 agit sur 1e microrupteur 57, qui excite 1'dlectro-ai- mant 55, ce qui a pour effet de ramener 1'ancre 6b dans sa position de repos, d'ouvrir Finterrupteur (1, 2) et par consequent d'eteindre 1e feu 4. The control device represented in FIG. 4 operates in the following fashion. When the brake pedal 27 is actuated for light braking, as is the case for example on a descent, the switch 51 is actuated by the cylinder 47. The switch 51 has the effect of lighting the first brake light 4. The latter goes out as soon as the pedal 27 is released. If the latter is on the contrary actuated violently, the switch 53 is also formed, which has the effect of exciting the electromagnet 54. This causes the anchor 6b to tilt around its pivot 7, which causes the closing of the switch (1 , 2). As long as the driver of the vehicle keeps his foot on the pedal 27, the switch 51 keeps the light 4 lit continuously. When pedal 27 is released, switch 51 opens, but switch (1, 2) closes. The timer 59 consequently causes the light 4 to flash. The latter only goes out when the driver of the vehicle activates the accelerator 31. the microswitch 57, which excites the electromagnet 55, which has the effect of returning the anchor 6b to its rest position, of opening the switch (1, 2) and consequently of extinguishing the fire 4 .
Comme dans la seconde forme d'execution, los dif- ferents circuits electriques du dispositif represente ä la fig. 4 sont alimentes par la meine Batterie 42. As in the second embodiment, the various electrical circuits of the device shown in FIG. 4 are powered by the same Battery 42.
Dans cette troisieme forme d'execution, an pourrait aussi provoquer 1e elignotement du feu 4 des quo 1e vehicule est soumis ä un freinage violent et pas seule- ment au moment oü la pedale de frein est relächee apres un tel freinage. A cet effet, il suffirait de remplacer la butee 11 par un second contact fixe, semblable au con- tact 1, de disposer un second contact mobile, sembla- ble au contact 2, sur 1'ancre 6b et de connecter 1'inter- rupteur electropneumatique ä basse pression 51 au se cond contact fixe, au lieu de 1e connecter ä la Batterie 42. En faisant basculer Pancre 6b, un freinage violent aurait alors pour effet d'ouvrir 1e second contact quo Pancre forme quand eile est au repos et de mehre 1'inter- rupteur 51 hors circuit, 1e circuit du feu 4 n'etant plus forme quo par Finterrupteur (1, 2), ä travers Je tempo- risateur 59. In this third embodiment, it could also cause the light 4 to go out whenever the vehicle is subjected to heavy braking and not just when the brake pedal is released after such braking. To this end, it would suffice to replace the stopper 11 with a second fixed contact, similar to the contact 1, to place a second mobile contact, similar to the contact 2, on the anchor 6b and to connect the switch. low pressure electro-pneumatic breaker 51 at the second fixed contact, instead of connecting it to the Battery 42. likewise the switch 51 is off, the circuit of the light 4 no longer being formed except by the switch (1, 2), through the timer 59.
