First Claim
1. In an illuminated safety belt buckle having a guasi-static light-conducting system with which movable cables and leads are completely eliminated, especially for a motor vehicle, having a buckle housing and a sliding key to actuate a securing device that is disposed in said housing to one side thereof and that, when an associated buckle tongue is inserted into a funnel-like insertion slot that is formed in the housing to the other side thereof, interlocks with said tongue, with a source of light being disposed in said buckle housing to provide illumination for said sliding key and said funnel-like insertion slot for said buckle tongue, including the improvement therewith wherein:
- said source of light is a single light source that is disposed directly longitudinally to one side in said buckle housing beyond said sliding key and said funnel-like insertion slot as functional components that are to be illuminated by said single light source in particular; and
a light-conducting path of highly transparent material is provided to couple said light source with said sliding key and said funnel-like insertion slot, with said light-conducting path comprising prefabricated material portions that are to be placed in said buckle housing, and with said light-conducting path having at least one tap that branches off between said light source and said sliding key on the one side and said funnel-like insertion slot on the other side.

Abstract
An illuminated safety belt buckle, especially for a motor vehicle, having a buckle housing and a key to actuate a securing device that is disposed in the housing. When an associated buckle tongue is inserted into the insertion slot formed in the housing, the securing device interlocks with the tongue. To provide illumination for the key and the insertion slot, a single light source is disposed in the buckle housing beyond these functional components. A light-conducting path of light-conducting material couples the light source with the key and the insertion slot.
