Definitions

  • the invention relates to a safety system in a motor vehicle with a closable with a flap engine compartment.
  • DE 103 33 382 A1 describes a device for firefighting, in particular in a commercial vehicle, which usually has a brake system actuated by compressed air.
  • a stored in a memory extinguishing liquid with the aid of existing in one or more compressed air tanks in the motor vehicle operating air is distributed via known devices, for example in the engine compartment of the motor vehicle, in order to combat such an emerging fire.
  • DE 90 12 180 Ul shows a control unit for fire extinguishing systems in motor vehicles with a three-way switch to test the functionality of the entire fire extinguishing system in a motor vehicle with the help of a test operation.
  • DE 87 15 208 Ul discloses a kit for a fire extinguishing device for motor vehicles with an extinguishing agent tank, connecting lines leading to spray nozzles, for example in an engine compartment of the motor vehicle, as well as the spray nozzles associated valves for opening the lines.
  • the kit is installed in a motor vehicle, with the spray nozzles arranged in the engine compartment, in order to be able to fight an emerging fire.
  • the object is achieved in that on an inside of the engine compartment filled with an extinguishing agent containers are arranged, which release the extinguishing agent when a limit temperature is exceeded.
  • the core idea of the invention is to use a passively acting system for fire fighting.
  • This consists essentially of one or more containers which are filled with any extinguishing agent, for example a liquid, a gas or a gel described below.
  • the containers or their walls are designed such that when a threshold temperature, as necessarily occurs in the occurrence of a fire in the engine compartment of the motor vehicle, the extinguishing agent release.

  • Hollow-sphere-like structures are preferably used as containers which are filled with an extinguishing gel, wherein the containers are preferably in the form of spherical wax envelopes, which melt when a fire is generated.
  • the extinguishing gel is designed in such a way that it contains on the one hand water to escape from the heat by evaporating the water and on the other hand foaming substances are contained in the extinguishing gel, for example, dripping onto an engine block and form an airtight foam layer on the hot metal of the engine block , whereby it is separated by the foam layer from the surrounding atmospheric oxygen.
  • sizing agents e.g. B. in the form of alkaline substances, containing the carbon in the lubricating oil or in the fuel together with the water contained in the extinguishing gel to enter an endothermic reaction
  • the advantage of the invention is that no electrical or mechanical components for triggering the security system are necessary, so that even with a complete failure of the on-board electronics by the automatic release of the extinguishing agent from the arranged in the engine compartment containers an emerging fire in the engine compartment of the motor vehicle reliably fought can be.
  • the containers are expediently configured in the shape of balls and / or pads and are preferably distributed over the entire interior of the engine compartment of the motor vehicle.

  • the extinguishant storage solid liquid or gaseous extinguishing media can be stored, for. As powder or CO 2 .
  • the extinguishing agent is preferably released by means of pumps via lines and nozzles and possibly the nozzles associated valves at suitable positions in the engine compartment of the motor vehicle to extinguish such a fire.
  • the control unit can also be integrated in a central control unit for controlling all functions of the motor vehicle.
  • the sensors for detecting a fire may be temperature and / or crash and / or airbag sensors. Temperature sensors are used to detect an increased temperature in the engine compartment with any desired measuring principles, with crash sensors, for example, a deformation - S -
  • the active safety system also has a fuel shut-off device to prevent the supply of further fuel from the fuel tank into the engine compartment.
  • a fuel shut-off device may for example be designed as a solenoid valve, which is also in communication with the control unit.
  • the safety system is also provided with a manual triggering device for triggering it, for example, by actuating a switch on the dashboard by an occupant of the motor vehicle.
  • a corresponding actuator may be provided to allow rescue workers to trigger the security system.
  • the active security system was associated with a passive security system. described. However, it will be apparent to those skilled in the art that the active safety system may be installed on a vehicle alone.
  • FIG. 1 shows a schematic representation of an engine compartment of a motor vehicle in cross section, but for simplicity without actual engine.

Abstract

L'invention concerne un système de sécurité d'un véhicule automobile placé dans un compartiment moteur (1) pouvant être fermé par un capot (2). L'invention vise à augmenter la sécurité passive du véhicule automobile. A cet effet, des contenants remplis d'un produit d'extinction sont placés sur une face interne du compartiment moteur (1) et libèrent le produit d'extinction lors du dépassement d'une température limite.
