description Helmut Franke Device for soft braking of passenger cars

The invention relates to a device for soft braking of passenger cars. You can both from the police can be used to stop escape vehicles as well as to protect construction sites.

Two situations are conceivable during police operations an escape vehicle is to be stopped:

1. The getaway vehicle is and is already recognized as such pursued by the police. But his direction of escape is not exactly predictable.

2. The police control all or some of the vehicles on a street. The road cannot be complete be blocked. A driver ignores the police stop signs and flees.

In case 1, the device must be used to gently brake the escape vehicle can be set up quickly in an unprepared location. In case 2, the device must be prepared in this way that it is ready for use within a few seconds.

It is common practice to create roadblocks to stop the escape vehicle by moving vehicles or nail chains. this can lead to rear-end collisions or after breaking the roadblock lead to dangerous chase drives. If you take into account that the escape is often only due to panic repulsion of the fugitive, these means are inadequate.

Construction sites are usually protected by optical means. To protect the construction workers are also sometimes Construction vehicles set up in front of the construction site. Driving on these leads to serious traffic accidents.

Mr. lireibun ^ Helmut Franke Device for soft braking of passenger cars

The invention is based on the object of a passenger car braking reliably and so softly that major injuries to the occupants are prevented. It is also necessary that the braking device, especially during police operations, transported in the trunk of a passenger car can be (case 1), or the structure can be prepared in such a way that the flowing traffic is little obstructed, the braking device is operational within seconds if necessary (case B).

The object is achieved according to the invention in that a safety net, consisting of inelastic stretchable plastic ropes or -belts parked on two parallel to the roadside or at an acute angle against the direction of travel of the escape vehicle Passenger car is attached.

According to a further embodiment of the invention, additional Shock absorption and energy absorption hydraulic shock absorbers in the vicinity of the coupling pieces in the horizontal bands of the network.

In order to be able to set up such a safety net quickly and so that it has the desired shape, after further training The invention sewn suitably shaped tubular air bags on the net, which are attached to the net from small compressed air bottles or cartridges are filled.

In order to be able to stop breaching vehicles immediately during a roadside check (case 2), the network can after another Embodiment of the invention designed in a protective cover on the street v / ground. It can be in this without being damaged Condition of vehicles being run over; If necessary, it can be done by letting the compressed air into the air sacs in a few Seconds to be erected.

Contraption; for soft braking of passenger cars

The advantages that can be achieved with the invention are that the escape vehicle without any major risk to occupants and Can be stopped by the police. The safety net can be set up in a very short time on almost any police operation Road possible without the need for special holding devices for the network.

An embodiment of the invention is shown in the drawing. Figure 1 a shows a top view and Figure 2 shows a side view of the stretched net. In Figure 1 b the state after braking is shown.

Horizontal and vertical bands of the network are at the crossing points tear-proof sewn. This ensures that all horizontal bands are stretched approximately equally. To a To avoid rolling over or under the net, the net has a concave shape, which is created by sewn air sacs. The horizontal bands are brought together at both ends of the net and sewn to a coupling piece that is attached to the Fastening devices of the parked cars can be hung. At this point you can add additional Shock absorption and energy absorption hydraulic shock absorbers inserted into the horizontal belts of the net. The passenger cars are used to accommodate the after the inelastic Deformation of the network remaining kinetic energy of the vehicle to be braked. They're dragged along until the getaway car has come to a standstill.

To secure a construction site, the net can be attached to sufficiently heavy, flat concrete slabs that are on the road surface be placed.
