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).

Abstract: An illuminated belt buckle for a seat belt device of a motor vehicle including a housing (1), a push button (2) displaceable in the housing (1), an insertion slot (12) delimited by an edge section (23) of the housing (1) and the push button (2) for insertion of a belt tongue that can be locked in the belt buckle, and at least one light-emitting surface (13,14). The light-emitting surface (13,14) having a linear contour, the shape of which matches the shaping of a laterally positioned edge side (24) of the push button (2) when viewed toward the insertion slot (12).
