Definitions

  • the invention relates to a buckle according to the preamble of claim 1 and the use of the buckle in motor vehicles.
  • Belt buckles with sensor units that detect the closing state of the buckle are known, for example from the publications DE 10 2006 061 033 AI and WO 2004/065843 A2.
  • Belt buckles with lighting units are also known, as disclosed for example in the publications DE 10 2007 047 704 AI, DE 197 29 567 C1 and DE 10 2006 008 251 AI.
  • the object of the invention has been found to propose a buckle, which is relatively inexpensive and / or easy to install and / or is compact and has both a sensor unit and a lighting unit.
  • the sensor lighting assembly is preferably designed so that it can be installed pre-assembled in the buckle.
  • the common sensor-illumination assembly is preferably understood as a sensor-illumination module.
  • the sensor illumination assembly comprises a base element, which is designed in particular as a leadframe on which the sensor unit and the illumination unit are arranged.
  • the lighting unit preferably comprises at least one lighting element, which is designed in particular as a light-emitting diode, and a light guide element, which is designed and arranged so that it leads light from the lighting element to at least one Gurtschbetuschistste.
  • the sensor unit and the at least one illumination element of the illumination unit are formed in each case or jointly as an electronic SMD component (surface-mounted device or surface-mounted component).
  • Gurtschlos süfus is expediently optically scattering and / or transparent or semi-transparent, in particular made of plastic.
  • the optical waveguide element has a convex optical design, in particular an optical lens, on the light-incident side, to which the illumination element is assigned, and has a concave optical design, in particular an optical lens, on the light-emitting side.
  • the light guide element in a housing part, especially preferably in a housing shell, integrated, for example by injection molding, wherein the light guide element is preferably advantageously arranged substantially centrally in or on the housing part.
  • the light guide element is formed as a glass fiber element, in which the convex and the concave optical training are integrated.
  • the belt buckle preferably has an at least three-wire cable connection which is electrically conductively connected to the base element designed as a leadframe, on which the sensor unit is arranged and is electrically conductively connected to the cable connection, the illumination unit being arranged directly in particular in the region of the cable connection is electrically connected to the cable connection or the leadframe.
  • the sensor unit expediently comprises at least one magnetic field sensor element, in particular a Hall element, as well as a permanent magnet, for detecting the closed state of the belt buckle.
  • the sensor illumination assembly comprises a housing segment of the buckle, in particular with locking elements for mounting or mounting the sensor lighting assembly in the buckle.
  • the at least one lighting element of the lighting unit is preferably dependent on the closed state activated by the buckle.
  • the buckle can take the closed states “open” and “closed”, wherein the closing state “open” is detected by the sensor unit when the closer of the belt is not or not completely or sufficiently engaged in the buckle or connected to this fully engaging is and wherein the closed state “closed” is detected by the sensor unit, when the closer of the belt is fully engaged in the buckle or is connected to this fully engaging.
  • the lighting unit in a closed state "detected" by the sensor unit, controls the lighting element so that it lights up and, in the case that the sensor unit detects a closed state "closed", the lighting element is driven so that it does not shines.
  • the lighting element is controlled in such a way that it constantly lights when the motor vehicle is switched off and flashes when the motor vehicle is switched on, in each case in the event that the closed state is "open.” In the event that the vehicle is locked or the doors of the vehicle are locked Passenger compartment are locked, but the lighting unit is turned off to avoid unnecessary energy consumption.
  • the lighting unit comprises two or more different lighting elements which have different colors, for example a green one and a red lighting element, wherein these different lighting elements are controlled in dependence of the detected by the sensor unit closed state.
  • the buckle control button is illuminated even in the "closed” state, for example, "green", which can be helpful in the dark.

  • Fig. 1 an exemplary buckle is shown, with sensor lighting assembly 1, comprising a lighting unit 3, with a light emitting diode 9 and a light guide element 5.
  • the sensor unit is not recognizable, since it is covered by the other components of the buckle.
  • the sensor lighting assembly 1 is powered by a three-wire cable connection 7 with electrical energy.
  • Light guide element 5 passes light from light emitting diode 9 to belt lock operating button 6, shown in an unactuated state, so that it is lit or optically better visible.
  • Fig. 2 shows the exemplary buckle of FIG. 1, some other internal components of the buckle are no longer shown, and so the housing 10 of the sensor lighting assembly 1 and its positioning in the buckle is better visible.
  • the sensor lighting assembly is designed so that it can be installed as an integrated module, for example, including the light guide element 5, which may alternatively be mounted separately or integrated in the housing shell 8, in a relatively simple manner together in the buckle.
