Definitions

  • the invention relates to a heatable vehicle window with a plurality of straight heating wires embedded in it, which run parallel to one another and at a substantially constant distance from one another almost over the entire window width and have busbars which can be connected to a direct current source only at their ends, the part of which Disk height-running adjacent heating wires are combined in sub-groups with heating wires connected in parallel, and the remaining heating wires are connected in parallel to form a residual group, and the busbars and the direct current source have a switch arrangement with a first switching position in which only the heating wires of the sub-groups are current-flowed when the sub-groups are connected in parallel, and with a second switching position, in which all the heating wires have current flowing through them when the subgroups are connected in series.
  • the invention has for its object to provide approximately the same load on the DC source in a heatable vehicle window of the type mentioned in both switch positions of the switch arrangement, with the heating wires in the first switch position having a significantly higher power per unit length than in the second switch position.
  • This object is achieved according to the invention in that in the second switching position the remainder of the sub-group is connected in parallel and that the number of heating wires in the remainder, the number of parts Groups and the number of heating wires in the individual sub-groups are coordinated so that the total resistance of the heating wires in the first and second switching position is substantially identical.
  • the invention is based on the knowledge that one can easily achieve approximately constant total resistance and thus constant load on the direct current source in the aforementioned switching of the heating wires by appropriate variation of the number and group assignment of the heating wires in both switching positions.
  • the subgroups preferably each have the same resistance and / or the same number of heating wires. Since, in general less sufficient than half of the disc height for rapid heating, it is recommended to make the number of the heating wires of all subgroups smaller than the number of the heating wires in the residual group 1. According to a further preferred embodiment, the! is of particular importance because it adds a further variation parameter, the heating wires have a different resistance per unit length, at least in groups. In this context, the variant in which the heating wires of the subgroups each have a lower resistance per unit length than the heating wires of the remaining group is particularly recommended. A practical,! The embodiment containing all the measures mentioned is characterized by nine heating wires in the remaining group and a total of six, one compared to the heating wires the rest Group halved resistance per unit length of heating wires in two sub-groups.
  • Fifteen straight heating wires 2, 3 are embedded in each of the two heated vehicle windows 1, which run parallel to one another and at a substantially constant distance from one another almost over the entire width of the window and have busbars 5 which can only be connected to a direct current source 4 at their ends.
  • the total of six adjacent heating wires 2 running in part of the disk height are combined in two sub-groups, each of which has three heating wires 2 connected in parallel.
  • the two subgroups are in the lower region and in the embodiment according to FIG. 2 in the middle region of the vehicle window 1.
  • the remaining, a total of nine heating wires 3 are connected in parallel to form a single remaining group.
  • the busbars 5 and the direct current source 4 is a switch arrangement 6 consisting of two coupled switches in corresponding connections; Interconnection lines.
  • the switch arrangement 6i is adjustable between two switch positions. In the ; In the first switch position (shown in dots in dots 1 and 2), only the heating wires 2 of the subgroups are energized when the subgroups are connected in parallel. In the second switch position (shown in solid lines in FIGS. 1 and 2), all heating wires 2, 3 have current flowing through them, the two subgroups being connected in series and the remaining group of the series connection of the two subgroups being connected in parallel. Different line widths in FIGS.
