  • the invention has for its object the generic actuator trained so that they are easy to assemble can and a failure or malfunction of the release even under extreme conditions is reliably avoided.
  • the trigger signal transmitted wirelessly from the actuator to the controller. Because of the wireless unlocking, lines are cables and the like not necessary. This makes it a very simple one Assembly of the actuator guaranteed. It is above Furthermore, not susceptible to faults and in particular free of wear. An outage or a disturbance of the unlocking is therefore also under extreme Conditions excluded.
  • the actuator is part of a passive receiver. It advantageously has a preferably as a planar antenna trained passive antenna.
  • the actuator and the controller are only a short distance apart, so that even low powers are sufficient to transmit the signal, to unlock it. So the distance between the actuator and the control, for example, only 1 to 2 cm.

  • a receiver 39 is located on the rear window 37 of the motor vehicle a button 1 is provided, which is connected to a planar antenna 2 is. It is adjusted to a predetermined value via a matching element 3 Tuned resonance frequency. In the simplest and preferred Fall is the adjustment element 3 by two parallel Capacitors 4, 5 formed. You can be adjustable.
  • the button 1 is pressed and thus the resonant circuit 6 closed.
  • the resonance frequency 13.560 MHz.
  • the resonance frequency be chosen differently.
  • the resonant circuit 6 with the planar antenna 2 and the button 1 forms a passive antenna. It does not have to be powered.
  • the battery voltage which in the example is 12 volts, is determined by a voltage regulator 15 stabilized, in the embodiment to 7 volts.
  • the input and the output of the controller 15 is in each case a resistor 35 and 36 assigned. That at the output of the controller 15 applied signal is fed to the plus input of the comparator 13, which is the controller signal with the rectified output signal of the oscillator 9 compares and delivers the control signal.
  • the oscillator 9 has a transistor 16 which is connected via the quartz 11 in Resonance frequency preferably 13.560 MHz (ISM band) to the transmitting antenna 8 is brought. It is advantageously a planar antenna. you connected in series are two series resistors 17, 18, a voltage divider to the base or to the working point of the Form transistor 16. Parallel to resistor 17 or in series with Resistor 18 has two capacitors 19, 20, which are used for the feedback are responsible for generating the vibration amplitude. A resistor 21 determines the emitter current to the transistor 16th
  • the oscillator 9 is provided with a low-pass filter 22 from the outside to screen out incoming interference.
  • the low pass 22 consists of a resistor 23, a capacitor 24 and a resistor 25 are subordinate.
  • Resistor 25 is in the collector circuit of transistor 16 is connected and is in series with resistor 18 of the voltage divider.
  • the rectifier 12 is advantageously temperature compensated so that the offset voltage of the comparator input not changed.
  • the rectifier 12 is included two diodes 26, 27 combined to form a unit, which are thermally integrated on a chip.
  • the decoupling point 10 on the oscillator 9 is formed by a capacitor that is set that the voltage is still so high that it Threshold voltage of the rectifier 12 exceeds sufficiently far, in order to enable a reliable evaluation in the comparator 13.
  • the decoupling point 10 of the oscillator 9 is a low-pass filter 28, 29 downstream to suppress RF interference from the outside could lead to an unwanted actuation of the control.

  • a low-resistance load 34 are operated.
  • the resonance circuit 3 By pressing the button 1 of the passive element, the resonance circuit 3 closed, whereby 7 energy is removed from the transmitter becomes. It leads to the triggering of a control signal, which causes the unlocking of the rear window 37 is reached.
  • the transfer between the passive element and the transmitter 7 are used the resonance frequency wired or wireless.
  • the passive Secondary circuit 6, which is tuned to the transmission frequency or via the button 1 is out of tune with the transmission frequency, deprives the In the resonance case, oscillator 9 has sufficient energy so that the waste the RF voltage across the RF rectifier 12 to the following Comparator circuit is detected. It provides a corresponding one at output 14 Logic signal to control a power FET switch 40, with which the unlocking of the rear window 37 is reached becomes.
  • the transmitter 7 Due to the wireless unlocking of the rear window 37 without use of lines, cables and the like results in a very simple assembly of the actuator. It is not prone to failure and is particularly wear-free.
  • the transmitter 7 only needs a minimum current, which is, for example, only about 3 mA. As a result, the transmitter 7 can also be in the standby position for a long time be without the vehicle battery which transmitter is connected, too much energy is being drawn.
  • the transmitter 7 with the central locking of the motor vehicle to couple. If the vehicle is centrally locked, it is too the transmitter 7 is switched off so that it does not require any current. Becomes the central locking is opened, the transmitter 7 is also switched on, so that it is ready for use. If the transmitter 7 via the central locking switched off, there is no possibility for unauthorized persons manipulate the transmitter 7 from the outside and the rear window 37 to open without authorization.
  • Fig. 5 shows a transmitter 7, in which the quartz 11 resonates with part of the antenna 8 and capacitors connected to it 41, 42 is. As a result, the load on the quartz 11 becomes low held.
