  • Headlight for motor vehicles, especially road vehicles
    Patent number: 4893218
    Abstract: A reflector, made from a thermosetting plastic, has three tightening faces on its crown neck that act as a catch, into which three protrusions, such as pawls, dig in a thread-like manner with teeth of the ring. As a result, the ring secures an incandescent bulb in the reflector. By means of this unilaterally acting friction catch, lateral slides, in particular, become unnecessary on an injection holder of the reflector, which is a considerable advantage in the processing of thermosetting plastics.
