Abstract: The present invention relates to an illuminated belt buckle (1) for a safety belt device of a motor vehicle. The illuminated belt buckle (1) comprises a housing (2), a push-button (3) displaceable in the housing (2), an insertion slot (4), bordered by an edge section (21) of the housing (2) and the push-button (3), for inserting a latch plate lockable in the belt buckle (1), at least one light source (10) and at least one light guide (11), wherein the light guide (11) is coupled to at least one light-emitting surface (12, 13) starting from a light entry surface (22). It is provided that a shielding element (14) is arranged on the light guide (11) and shields the light guide (11) at least from a housing part (7, 8, 9) of the housing (2) and/or a cavity (15) in the interior of the housing (2) in which the push-button (3) is arranged. The invention also relates to a method for producing such an illuminated belt buckle (1).

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).
