Definitions

  • the invention relates to a device for monitoring the closing process of a motor-driven window pane, in particular a motor vehicle window pane, with a transmitter and a receiver for electromagnetic radiation, with at least one light-deflecting means which conducts the electromagnetic radiation from the transmitter to the receiver and in which the window pane is driven is stopped or vice versa if the radiation intensity recorded by the receiver changes during the closing process of the window.
  • Such devices are known and are used to prevent the trapping of limbs or objects during the closing process of a motor-driven window.
  • DE-PS 31 07 847 proposes a device in which a light guide is attached along the closing edge of a window frame and guides a light beam from a transmitter to a receiver by means of total reflection. If this light guide, which is designed as an optical fiber bundle, is pressed together, for example because an object is jammed between the window and window frame, the light intensity received by the receiver changes, whereupon the window drive is stopped or reversed.
  • the disadvantage is even more serious that the light guide must be deformed in order to respond to this monitoring device, so that the monitoring device only reacts after an object or a body part has already been pinched with a certain force.
  • the object of the invention is therefore to provide a monitoring device which is of particularly simple and inexpensive construction and in which it is possible to influence the window pane drive without a pinching process taking place.
  • the light-deflecting means is arranged along, at least in part, the upper edge region of the window opening.
  • Refractive or reflecting means can be provided as light-deflecting means.
  • Suitable refractive agents are, for example, prism and / or lens arrangements which conduct the electromagnetic radiation from the transmitter to the receiver.
  • Reflective means can be suitably designed flat or concave reflection surfaces, via which the electromagnetic radiation is guided from the transmitter to the receiver by means of single or multiple reflection.
  • the infrared light is guided to the receiver by the light-deflecting means along the upper edge region of the window opening. If an object or a body part comes into this area during the closing process of the window, only a reduced radiation intensity reaches the receiver, which then causes the pane movement to be stopped or reversed via control electronics.
  • a particular advantage of such an arrangement is that no light-guiding medium is used, the light-guiding properties of which are changed by an external force, as is the case, for. B. is the case with an optical fiber bundle or with a compressible, internally mirrored hose or tube.
  • the arrangement is also particularly simple and inexpensive since, despite the curved beam path, only one transmitter and receiver is required.
  • the design of the light-deflecting means is also possible without any special effort.
  • a particularly inexpensive arrangement can be obtained in that a radiation transmitter is irradiated with several receivers or a receiver is irradiated with several transmitters, the individual element being arranged at a suitable, central location between the multiple elements.
  • a reflecting means for example a mirror
  • the transmitter and receiver can be arranged in one housing.
  • structures with several transmitters and / or receivers are also possible here.
  • an area of the underside of the upper door pillar can be designed as a reflecting means, for example by polishing the surface thereof and is covered with a reflective varnish. This configuration is particularly advantageous in view of the low cost of materials.
  • a strip of metal foil or sheet metal can also be applied as a reflecting agent along the underside of the upper door spar.
  • Such a design offers the advantage that no special requirements have to be made of the shape of the door spar and that no subsequent shaping measures have to be carried out on it, since the specification of the light path is brought about by the shape of the reflecting means applied and, for example, easily by bending a sheet metal strip acting as a reflecting agent can take place.
  • the reflective means is designed as part of an interior door panel.
  • the direction of reflection can be predefined in a simple manner by the shape of the inner door lining without the need to change the door frame.
  • the protective layer can, for. B. can be designed as a dark infrared-transparent plastic film or as an infrared-transparent lacquer layer.
  • Such protective layers can also bring about an improvement in the aesthetic effect of the reflective agent, in particular if the reflective agent is in the form of a brightly polished metal surface.
  • FIG. 1 shows the external view of a motor vehicle door which has a motor-operated window pane (1) and a monitoring device according to the invention.
  • a reflective means (4) is attached to the inside of the door in a manner to be described.
  • An infrared radiation transmitter (2) or an infrared radiation receiver (3) is arranged on the door on each opposite side of the upper edge region of the window opening or is embedded in the door.
  • At least part of the radiation intensity emitted by the transmitter (2) reaches the receiver (3) from the infrared transmitter (2) via single or multiple reflection.
  • a possible beam path is shown as an example in FIG.
  • FIGS. 2 and 3 show a cross section through the area marked A-A in FIG.
  • the reference symbols for identical or equivalent objects correspond to those in FIG. 1.
  • Figure 2 shows a cross section through the upper door spar (7).
  • the upper door spar (7) is one Rubber seal (10) fitted into which the motor-driven window pane (1) runs in during the closing process.
  • a flat area of the upper door handle (7) is used here as reflecting means (4).
  • the surface of the door bar plate has been polished in this area to achieve reflective properties. It is advantageous to provide this area of the door spar (7) with a protective cover (9).
  • a protective cover (9) For example, an infrared-transparent protective lacquer or an infrared-transparent film is suitable for this.
  • the door spar (7) can also be provided with a reflective lacquer layer. Polished metal foils or metal sheets which are applied to this area of the door spar (7) are also suitable as reflecting means (4). The shape of the applied metal foil or sheet can easily be used to specify the beam path from the transmitter (2) to the receiver (3).
  • the reflective means (4) is formed here by a reflective surface on the inner door panel (8).
  • the reflective surface which is applied at a suitable point on the inner door trim (8), can also be designed here as a reflective lacquer layer or as a polished metal foil or sheet metal.
  • a particular advantage of this embodiment can be seen in the fact that the adjustment of the light path by means of shaping measures, for example the door interior trim (8) can be done before attaching the door lining (8) to the door spar (7).
  • the assembly and adjustment of the reflecting means (4) can therefore advantageously take place independently of the assembly of the door frame.
  • the reflecting surface (4) applied to the door interior trim (8) is also covered in this exemplary embodiment by a suitable protective layer (infrared-transparent plastic film or infrared-transparent protective lacquer or the like).
  • the beam path (11) of the light directed from the transmitter (2) to the receiver (3) is shown in a highly simplified manner.
  • different beam paths are possible, in particular depending on the shape of the reflecting means (4), in particular by means of multiple reflections. It is therefore advantageous to design the receiver (3) or the electronics connected to it in such a way that it does not react solely to a lack of light, but already to a reduction in the light intensity, so that the window drive is influenced as soon as a possible light path is interrupted.
  • the control circuits or the mechanical part of the window drive are well known, so that it can be omitted here.
  • the only advantageous measures to be proposed here are that the transmitter (2) is operated in pulsed mode and the receiver (3) should be provided with a tube in order to rule out interference from direct or scattered light and to further increase the sensitivity of the system.
