Apparatus for releasably attaching a lamp on a reflector of a motor vehicle headlight

Apparatus to releasably attach a lamp to a reflector of a motor vehicle headlight, wherein the reflector has an opening therein for receiving the lamp, with a glass bulb of the lamp extending through the reflector from a rear side thereof, the lamp having a socket with a surrounding flange from which radial positioning ears extend outwardly for engaging a plastic attaching ring which is affixed to the reflector so as to surround the opening said plastic attaching ring having spring tongues formed thereon between which the positioning ears of the lamp socket can be placed for engaging the positioning ears with the spring tongues upon a screwing motion of the lamp about its length axis so that the positioning ears glide along tongue contact surfaces until the tongues, at an end position of the lamp, lie biased against the positioning ears, with the flange of the socket pressing against a ring contact surface facing in an opposite direction from a mounting direction of the lamp;

• wherein the attaching ring is formed as one piece to comprise the spring tongues and an inner rim portion extending in a spaced relationship to the tongue contact surfaces between the spring tongues and the reflector, said inner rim portion providing the ring contact surface facing the tongues for engaging the flange of the socket of the lamp;
• wherein the inner rim portion is circular and has a radially outwardly directed wall portion extending beneath the respective tongues;
• wherein the wall portion of the inner rim portion is formed from a one piece ring-shaped disc extending in spaced relationship to the spring tongues;
• wherein each tongue of said spring tongues is respectively coupled to the ring-shaped disc, which is arranged to be displaced from the reflector, by end walls whose inner sides, which border the underside of the respective tongue, extend so that they, together with the underside of the tongue and the side of the wall portion facing the tongue, can be molded during molding of the attaching ring by a mold part of an adjustable mold which can be moved outwardly.
