Carburetor throttle causes. The head 3a is here of the piston 5 with a stop 17 of the carburetor 13 in contact. If desired, this stop 17 can also winke1-raäBig be adjustable to each other compared to the piston head 3a to be able to provide a specific one of a multiplicity of surfaces 17a, each with a different radial At a distance from the axis of the abovementioned stop, as can be seen from FIG. 4 of the drawings, is in the present Case the warning system with a pair of backwards and in appropriate Catfish grounded warning lights 18 are provided, which are ever preferred are colored amber and have a triangular shape, as it is in Flg. 6 and 7 is shown. The respective form and the shape of such rear warning lights can, however, also be configured differently depending on requirements, wherein it is still easily possible to equip the system with just a single such lamp.

In any case, the system is designed so that if the operator releases the throttle to then start with Stepping on the same foot on the brake pedal, the piston head 3a alters the stop by the rotary movement of the army 11a 17 is brought into contact to fix the throttle while the throttle valve is still open by the respective amount, so that the idle or a slower running of the Ho sector is present. However, this is still going on during this movement

of the piston 5 to contact the head against the contact 17, this piston 3 is initially actuated against the action of the spring 6 so that the switching element 7 is brought into contact with the two switching elements 9, thereby closing the pre-braking warning circuits and the light up rear or rear warning lights. This process occurs while before the FuS the operating jm "reaches the person BremsfuShebel so that the warning lamps light up before the brake lights are set in motion. In addition, the piston head Ja is held firmly against the spring force in such a position that the switch remains in its closed position in any case, but if, on the other hand, the switch is moved away from the stop 17 by stepping down the throttle lever together with the Arn 11a in the direction of stop 17 and from the same is released, then the piston j5 is also released and moves slob under the action of the spring 6 into a position in which the switch W is open, so that the warning lamp or lamps go out.

In the so shown in Fig. 4, the safety switch is of the invention generally referred to as S. One of the wires 8 going out from holder S is connected to the one Side of the ignition switch, while the other wire 8 is connected to one of a pair of rear warning lights18 connected in series and grounded.

If desired, this system can also additionally contain the grounded indicator light 19 that operates automatically lights up and goes out when the warning lights 18 light up or go out. If such an indicator light is visibly affixed in front of the driver of the vehicle »then can the same appoint whether the warning light or «actually shine work·

A further implementation possibility for the invention is given if the safety switch is not used in place of the usual adjusting screw for the idling of the carburetor, but if an arrangement is found in which the switch is operated directly by the throttle lever itself. Such an arrangement is illustrated in Fig. 3 of the drawings. in which the tubular switch housing 2 in one; KiIc 20 is arranged, which is fastened to the vehicle by means of screws, so that the 3-piston head 3a is opposite the upper one of the throttle lever 22. If the throttle is now released or the pressure of the operator's foot on the lever is released, the throttle lever 22 goes up and comes into contact with the old atm piston head 3a in such a way that the safety switch is closed. By stepping down on the throttle lever, on the other hand, "ie by moving in this way in the direction of arrow A", it becomes possible for the piston 3 to move out of the action of the spring 6

In the execution examples described so far, the Effect such that the warning lights of the foremost The warning system lights up every time the operator interrupts the foot pressure on the accelerator pedal. this has however, the result is that the said lights 18 also then Light up temporarily when an Oangwehsel is carried out, unless special measures are taken here. If it is desired that the possibility be switched off, The following drivers are confused by the lighting up of the warning lights every time the vehicle changes gear is carried out, then precautions must be taken to close the safety switch by an automatic and at the same time opening the Waraetroakrelses every time then to neutralize «when the clutch pedal of the vehicle is operated. For this purpose it is preferred, if desired, a swelter safety switch S1 according to FIG. circle included with respect to the clutch lever 23 so arranged and operated by the same as it is in the first-mentioned switch S with respect to the throttle lever Case 1st (Fig. 3), but with the following essential Difference. If you see the vehicle in normal driving, then the first switch 8 (Flg. 5) remains in its switched off or open position and is only closed when the pressure on the oas lever is released,

909832/0271

U55742

while the other switch is switched on or closed position and is only temporarily opened when the clutch pedal is depressed will. Thus, when the vehicle is in normal driving mode, the right foot of the vehicle driver rests on the oaspedal and his left foot is empty and at rest remains, then the first switch S is opened, while the second Sohalter Sl is closed (see the full lines in Flg. 5), the rear warning lights 18 remaining switched off. Takes now the driver to suddenly reduce the driving speed his right foot off the accelerator and puts it on the brake pedal, with his left foot still remains in the rest position, then there is an open » The rear warning lights 18 light up during the tent duration, during which the right foot moves from one to the other Lever is translated and before the brake pedal is depressed, as described above. These Possibility is given by the fact that during breeding the clutch pedal is not depressed, so that the zwdbe switch S1 is switched on in its closed position Position remains. However, during a gang bang, if the brake pedal is not touched and a balance between the actuation of the throttle lever and the clutch lever

takes place against each other, the switch S is initially simultaneously with djin open the switch Sl closed and then the latter switch is closed at the same time as the switch S is opened, so that the overall situation occurs that the rear warning lights remain completely switched off while the signal change is being carried out.

It is not necessary that the Pig. I pictured Safety switch always receives the embodiment shown and described.

One or more can easily be provided To have pins received by the tubular housing in such a way that that the same either with a plate or a corresponding one Element or a base or bases cooperate, which are assigned to the piston under spring pressure are or vice versa. On the other hand, you can also provide a metallic cap over one end of the tubular Housing f ^ st overlaid and combined with a clamp so that it works together with a flange on the piston, which is connected to another terminal.
