Definitions

  • the invention relates to a safety device for an electric motor drive according to the preamble of the main claim.
  • DE-OS 31 11 684 describes an electronic safety control circuit for driving a car window.
  • the control circuit comprises an electrical conductor arranged along the upper edge of the glass pane as a sensor which can be influenced capacitively and which is part of a control circuit.
  • This control circuit must be designed in a very complex manner, since different interference signals must be separated from the useful signal and recognized.
  • This safety device is only suitable for sunroofs or window panes, which consist of an electrical insulating material, e.g. B. plastic. However, this is a significant limitation. Movable feed lines are also necessary, so that additional space is required and the window can easily be blocked.
  • the safety device according to the invention with the characterizing features of the main claim has the advantage that it can be used regardless of the material of the moving part. She only works in emergency situations. The drive is not switched off during normal jamming, such as when the panes tilt or freeze. Even before the actual pinching, if e.g. B. Children with their chin resting on the window, a load can be detected and the engine can be switched off.
  • the manufacturing costs for the optical fiber guide are very low; a simple electronic evaluation circuit can also be used.
  • the optical fiber conductors used have a high degree of flexibility and are therefore very elastic, so that no additional movable feed line to the disk is required.
  • a reference light guide can suppress interference such as aging and fluctuations in the operating voltage of the radiation source.
  • the optical fiber conductor can be arranged directly in the surface of the window pane without additional protective devices.
  • FIG. 1 shows a first exemplary embodiment with the window normally closed
  • FIG. 2 when there is a risk of being caught
  • FIG. 3 shows a second exemplary embodiment
  • FIG. 4 shows an evaluation circuit to explain the mode of operation
  • FIG. 5 shows a special design of the fiber conductor.
  • 10 denotes a side window of a motor vehicle, which is moved back and forth by an electric motor.
  • the upper edge 11 of the side windows 10 is inserted into a sealing lip 12, which is located in a metallic window frame 13.
  • One or two optical fiber conductors 14 are embedded in the sealing lip 12.
  • a normal closing of the side windows 10 is shown in FIG. When closing, the side windows 10 are inserted into the sealing lip 12 without deforming the optical fiber conductors 14.
  • the radiation emitted by a radiation source 18 shown in FIG. 4 can pass through the fiber conductor 14 to a receiver 19 without being disturbed.
  • FIG. 3 A second exemplary embodiment is shown in FIG.
  • the optical fiber conductor 14 is not arranged in the sealing lip, but in the upper edge 11 of the side window 10 in a longitudinal groove 24.
  • the fiber conductor 14 is extrusion-coated with a plastic layer 25.
  • the amount of radiation passing through the fiber conductor 14 is already when the arm rests on the upper edge 11 of the side window 10 decreased. However, this can already be taken into account by specifying a corresponding threshold value in the threshold switch 22. It can be set such that the amount of radiation is noticeably reduced and the motor is only switched off when the arm is slightly pinched between the sealing lips 12. However, the electric motor can also be switched off before the actual clamping.
  • the fiber conductor is also arranged in the side edges of the pane, which are always guided in the window frame. Since the fiber conductor itself has a high degree of flexibility, no additional movable feed line is necessary. The fiber conductor 14 yields during the movement of the disk.
  • a second fiber conductor 26 as a so-called reference line, for example in the door frame.
  • the radiation emitted from the radiation source 18 reaches the receiver 19 without being influenced.
  • the measurement effect can be further increased if the distances between the pressure points are adapted to the distances of increased radiation intensity in the fiber guide 14.
  • These distances of increased radiation intensity depend on the fiber geometry, the fiber material and the wavelength of the radiation used .
  • These local contact points can also by a sufficiently hard, helical winding of the fiber conductor 14, z.
  • the safety device can also be used for sunroofs of motor vehicles.
