Accident and breakdown warning device for motor vehicles

The present innovation relates to an 'iciail and breakdown warning device for motor vehicles which ttaem motor vehicle drivers an accident, one driving in front of him and possibly for him, for example because of fog - still invisible motor vehicle.

With increasing traffic density and thus also increasing frequency of accidents, one is at the expense of opening> _x i »» r. .el endeavors to reduce the risk of accidents. An essential ** & play those measures that the forcer _. See and be seen ". Light-reflecting and self-illuminating warning devices are prescribed which must be used in the event of breakdowns and accidents in order to warn the following traffic.

However, there are numerous situations in which all have been known to date Warning devices could no longer fulfill their purpose: In the event of a collision, the front lighting

Tung destroyed. Often the vehicle turns around its vertical in the opposite direction, so that the possibly on Rear still functioning flashing system for the following traffic not see! s3.r is. If the leader does not hurt is more able to set up his "warning triangle" at a sufficient distance, there will be more vehicles with a high degree of probability involved in this accident. This means that - especially when it is foggy - there are frequent rear-end collisions on the autobahn with deaths, many injuries and obvious material damage. Such mass accidents are often caused by a very simple breakdown triggered because the driver of the stopped vehicle for the speeds usual on highways cannot deploy his warning device quickly enough.

The present innovation is therefore based on the task of providing an accident and breakdown warning device for motor vehicles create that switches itself on automatically in an accident, both when the vehicle hits an obstacle or turns over, as well as when it is or is rammed by another vehicle - regardless of the direction from which it is coming being hit by a falling tree. The device should work independently of the vehicle's electrical system, Can also be switched on by hand - for example in the event of a breakdown - and also in dense fog or other total visual impairment be effective.

According to the innovation, this is achieved by an in the motor vehicles arranged small radio device with a signal emitting transmitter and a receiver, which can be switched on and off by hand A power switch is also assigned to the transmitter, which is activated in the event of a shock caused by a collision or the like of the vehicle comes into operation while the receiver

is switched on when the vehicle is in operation or can be switched on manually as required.

The on-switch assigned to the transmitter is made according to the invention from a housing in which a weight is arranged in a detent releasable against an adjustable resistance, wherein one end of the switch line to the housing and the other End is associated with the weight.

The innovation is explained in more detail with reference to a drawing that shows it, for example. Show it:

1 shows a schematic representation of the entire device, FIG. 2 shows the automatic switch-on of the transmitter.

The device consists of a small radio device 1 with a transmitter 1 a and a receiver 1 b, the transmitter of a vehicle naturally interacting with the receivers of the other vehicles in the vicinity. While the receiver Ib analogously to the illumination in the dark, fog, or other visual obstruction by hand eingebchaltet - it may also in principle at ^r peration of the vehicle to be switched on - the transmitter la ei power switch 2 is assigned, the ien automatically in a collision or the vehicle overturning Transmitter la switches on. This then emits a radio signal, which is received by the vehicles in the vicinity and there is perceived by the drivers as an acoustic or optical signal. A range of a few hundred meters for the transmitter is sufficient for the drivers of the vehicles in the vicinity to be able to adjust to an obstacle on the roadway.

In the exemplary embodiment shown here, the on / off switch 2 consists of a vertically arranged cylindrical metal housing 3, in the cover 3a of which a helical spring 4 is fastened in an electrically insulated manner and which has a metal ball 5 at its free end wearing. Also electrically insulated, a screw 6 is arranged in the bottom 3b of the housing 3, and its screw 6 is inserted into the housing 8

protruding end is designed as a trough 6a in which the Metal ball lies. The screw 6 is screwed so far into the housing 3 that the metal ball 5 under slight pressure Spring 4 is pressed into the trough 6a, with the tension of the Spring 4, which can be regulated with the screw 6, the sensitivity of the switch 2 is adjustable. One end of the Switch line is connected to the housing 3 and the other end to the spring 4 with the metal ball 5. With a side Impact - no matter from which direction - or if it falls over of the vehicle, the metal ball 6 jumps out of its holder due to its mass wear and is between the Screw 6 and the wall of the housing 3 held by the spring 4. In this position the switch is closed and the transmitter is switched on. Due to its construction, this is a power switch 2, however, largely insensitive to vertical impacts, such as when driving through potholes and the like appear.

In order to also switch on the transmitter la emitting the warning signal by hand - for example in the event of a flat tire or the like to be able to, the automatic on / off switch 2 is a bridging line 7 assigned to a manual switch 8. Furthermore, the on-switch 2 and the manual switch 8 are suitable Signal generator (not shown in the drawing) assigned, which indicates to the driver whether his own warning transmitter is switched on or not.
