Method of production of a reflector wall having a core of thermosetting material enclosed in a skin of thermoplastic material, by two-material injection molding. Between a concave mold face having projecting points and a convex mold face, a thermoplastic skin material and a thermosetting core material having a polycondensation temperature greater than the plasto-elasticity temperature of the thermoplastic skin material are successively injected, while holding a temperature intermediate between the two temperatures; the points cause in the skin material interruptions permitting the emergence of the core material to the concave mold face, in localised zones of this in which open vents; the polycondensation of the core material and the hardening of the skin material is successively caused.

Method of producing a reflector for a headlight, particularly for an

The present invention relates to a protective cap for a motor vehicle headlamp and is intended to be mounted on the rear of a reflector (100) incorporated in the headlamp. The cap comprises an enveloping sleeve (20) which has inwardly projecting fastening means (21, 22) for co-operating with a rim (111) on the headlamp. The sleeve also has a flexible sealing lip (30) which rests, in use, against the reflector. According to the invention, the fastening means are arranged in a plurality of levels of generally annular structures projecting from the inside face of the sleeve and axially spaced along said inside face (23). In addition, the sealing lip is suitable for withstanding deformation including a radial component which is of the same order of magnitude as the axial separation between two adjacent levels of the projecting structures, while still providing proper sealing for the rear surface of the reflector (100).

Universal protective cap for motor vehicle headlamps

The device is of the type comprising a lamp-supporting ring (10) having an opening for receiving the base of a lamp, and a clip (30) in the form of a loop of wire which is pivotally mounted to one side of the said opening to pivot between an open position in which the opening is clear and a closed position in which the clip locks a lamp in position. The device includes the improvement wherein a first end (32) of the said wire is pivotally mounted in at least one bearing (16) provided on the said one side of the ring, and wherein the opposite end of the clip (40) is so shaped as to present a cradle suitable for receiving a portion of the first end and for being itself received, when the clip is in the closed position, in a recess (42) provided in the ring. The device is particularly intended for use in car headlights.
