Definitions

  • the invention relates to a security alarm system for vehicles of the type mentioned in the preamble of claim 1.
  • the acoustic signal generator of such alarm systems is activated by a trigger when unauthorized persons attempt to open the door lock and / or to actuate the starter and / or to break a window of the vehicle.
  • the security alarm system according to the invention is intended in particular for protecting the driver of the vehicle against attacks from outside or against attacks by passengers. Because it is often desirable that e.g. a driver of a vehicle who is in an emergency situation or a driver who is threatened by another vehicle occupant has the possibility of making others aware of himself and the existing emergency situation in order to have help brought in, in particular by the police. In addition, there are sometimes emergency situations after accidents in which e.g. a vehicle that has strayed from the road falls over an embankment into the adjoining terrain without the accident being perceptible to others. In these cases, too, it makes sense for a possibly injured driver to be able to draw attention to his or her emergency state for bringing help.
  • a taxi alarm system that can be triggered by hand or foot operated by a taxi driver and causes the horn and headlights and / or the taxi roof sign to flash is known from "Motor-Rundschau" 23/1967, pp. 10 ff.
  • a taxi alarm system is insufficient because it does not reveal a separate emergency call as a sign of a personal dangerous situation.
  • the invention is therefore based on the object of specifying a safety alarm system for vehicles, which is used to protect a vehicle driver is easy to activate in order to make others aware of a certain emergency situation inside or on the vehicle.
  • a security alarm system of the type mentioned at the outset in that at least one acoustic signal transmitter and at least one optical signal transmitter arranged on the vehicle are provided, which can be perceived by others, and a blocking or control device is provided, which keeps the acoustic and optical signal transmitter in the activated state after activation, their deactivation being possible only by using a key element and / or a predetermined coding and / or a contactless switch-off device (magic eye).
  • the trigger which can be designed for any conceivable triggering possibility and is preferably within reach of the vehicle driver, e.g. can be a trigger operated by hand or foot or actuated by acoustic code, heat receptors, light barrier ("magic eye”) etc., furthermore at least one optical signal transmitter and one acoustic signal transmitter, at least one of the optical signal transmitters being located on one for another clearly visible location of the vehicle and a blocking or control device which, after the alarm is triggered, keeps the activated acoustic and optical elements in their activated state.
  • the alarm which keeps the activated acoustic and optical signal transmitters in their activated state by the blocking or control device
  • This can be done, for example, by inserting a key element and / or by mechanical (manual) or foot-operated, acoustic or electronic code word or code number input or "magic eye", so that the driver himself cannot switch off the triggered alarm system is and can also not be enforced by a person who may threaten the vehicle driver.
  • the safety alarm system can therefore only be switched off by inserting a corresponding key element, e.g. a plug, magnetic or chip card or the like and / or by entering a mechanical and / or acoustic code, such devices preferably being in the possession of authorized persons only, such as e.g. the police or security and auxiliary services, so that the security alarm system according to this embodiment of the invention can only be switched off by these authorized persons called.

This prevents improper triggering of the safety alarm system and prevents a person threatening or attacking the driver from turning off the alarm himself or having the driver turn it off.
  • the safety alarm system according to the invention can be switched off again by the vehicle driver himself.
  • this switch-off option will always be coupled with a certain difficulty for the person triggering the alarm to be able to actuate the switch-off device from the place of the triggering, so that the same effect is achieved to prevent improper triggering of the system as is also the case in the first embodiment is achieved through the exclusive intervention of the police or authorized persons.
  • the switch-off device will either be arranged invisibly (as a heat or photoreceptor or acoustic or optical barrier, such as "magic eye") in the vehicle interior, so that the threatened driver can pretend that the system cannot be switched off , and the threatener himself cannot find the switch-off device.
  • the switch-off device can also be difficult to access or attached to the outside of the vehicle, which also has the advantage that the vehicle driver cannot be easily forced to switch off the safety alarm system.
  • the difficulty in accessing the switch-off option also guarantees that the acoustic and visual alarm signals, which, as in the first embodiment, can lead to the police becoming aware of the alarm-triggering vehicle and coming to the aid of the threatened driver.
  • the safety alarm system can only be switched off by a switch, plug, chip card or similar switch-off device located on the outside of the vehicle, there is also the advantage that the deactivation of the system stops the vehicle depends on what creates an additional possibility for the threatened driver to catch the attention of others or to escape the threat of flight.

  • one or more inflatable, balloon-like display devices 9 can be provided in the roof area, which are inflated in the manner of an airbag when the trigger 1 is actuated and have a striking emergency display on their surface.
  • a third possibility consists in attaching one or more hinged signs, panels, pyramids or the like 11, which normally lie flat on the roof and are erected when actuated and also carry a striking emergency display.

Abstract

L'invention concerne un système d'alarme de sécurité pour véhicule, qui comprend un dispositif d'alarme caractérisé par au moins un émetteur acoustique de signaux et au moins un émetteur optique de signaux, monté sur le véhicule, que d'autres personnes peuvent percevoir. Les deux émetteurs peuvent être activés pour attirer l'attention du conducteur sur une situation d'urgence. Le système d'alarme de sécurité comporte un dispositif de blocage et de commande qui maintient l'émetteur acoustique de signaux et le ou les émetteur(s) optique(s) de signaux à l'état activé, après leur activation. La désactivation de ces émetteurs de signaux ne peut s'effectuer que dans des conditions particulières, notamment à l'aide d'une clé et/ou d'un code prédéfini ou à l'aide de décodeurs optiques et acoustiques, de barrages photoélectriques ou de détecteurs thermiques de proximité.
