Abstract

Bei einer beheizbaren Fahrzeugscheibe 1 mit mehreren parallelen, über endseitige Sammelleiter 5 mit einer Gleich­ stromquelle 4 verbindbaren Heizdrähten 2, 3 sind die Heizdrähte 2 in einem Teil der Scheibenhöhe in Teilgruppen mit jeweils parallelgeschalteten Heizdrähten 2 zusammenge­ faßt. Die übrigen Heizdrähte 3 sind zu einer Restgruppe parallelgeschaltet. Den Sammelleitern 5 und der Gleich­ stromquelle 4 ist eine Schalteranordnung 6 zwischenge­ schaltet. In einer ersten Schaltstellung sind nur die Heizdräh­ te 2 der parallel-geschalteten Teilgruppen stromdruchflos­ sen. In einer zweiten Schaltstellung sind alle Heizdrähte 2, 3 bei hintereinandergeschalteten Teilgruppen stromdurchflos­ sen. Etwa gleiche Belastung der Gleichstromquelle 4 in beiden Schaltstellungen erreicht man, indem die Restgruppe in der zweiten Schaltstellung der Hintereinanderschaltung der Teilgruppe parallelgeschaltet wird und die Heizdrähte 2, 3 den Teilgruppen bzw. der Restgruppe so zugeordnet werden, daß der Gesamtwiderstand in beiden Schaltstellun­ gen im wesentlichen identisch ist. In the case of a heated vehicle window 1 with several parallel, via end-side busbar 5 with an equal Current source 4 connectable heating wires 2, 3 are the Heating wires 2 in a part of the disc height in sub-groups together with heating wires 2 connected in parallel sums up. The remaining heating wires 3 are a residual group connected in parallel. The common conductors 5 and the same Current source 4 is a switch arrangement 6 intermediate switches. Only the heating wires are in a first switch position te 2 of the sub-groups connected in parallel without current sen. In a second switch position, all heating wires 2, 3 are with sub-groups connected in series without current sen. Approximately the same load on the DC power source 4 in Both switch positions are achieved by the rest of the group in the second switching position of the series connection the sub-group is connected in parallel and the heating wires 2, 3 assigned to the subgroups or the rest of the group be that the total resistance in both switching positions gene is essentially identical.
