Illuminated belt buckle for a seat belt device of a motor vehicle
First Claim
1. An illuminated belt buckle for a seat belt device for a motor vehicle, comprising,a housing,a push button that is displaceable in the housing,an insertion slot for inserting a belt latch that can be locked in the belt buckle,the insertion slot bounded by an edge section of the housing,at least one light source,at least two light emission surfaces that are arranged at different, opposite edge sides of the push button whereinthe light source and the at least one light emission surface are connected via at least one optical waveguide, the optical waveguide includes a light entry surface associated with the light source and two separate light emission surfaces, wherein the optical waveguide branches from the light entry surface into two separate branches, wherein each one of the two separate light emission surfaces is associated with one of the two separate branches,a deflecting element arranged or formed on at least one boundary surface end of the two separate branches of the optical waveguide or on at least one boundary surface of each of the two separate light emission surfaces,the deflecting element having a geometry that differs from the rest of the boundary surface of the optical waveguide or the light emission surface.

Abstract
An illuminated belt buckle (1) for a seat belt device of a motor vehicle, having a housing (2), a push button (3) displaceable in the housing (2), an insertion slot (4) bounded by an edge section (21) of the housing (2). A light source (10) and the at least one light emission surface (12, 13, 38, 39) are connected via at least one optical waveguide (11), and wherein a deflecting element (14, 15, 16) is arranged or formed on at least one boundary surface (7) of the optical waveguide (11) and/or on at least one boundary surface (8, 9) of the light emission surface (12, 13, 38, 39). The deflecting element having a geometry that differs from the rest of the boundary surface (7, 8, 9).
