Definitions

  • the invention relates to a headlight for vehicles with a reflector, with a lens covering the reflector, with one in an opening of the Reflector used light element, with a between the light element and the lens arranged aperture, which is a separate part and has at least one support arm through the opening of the reflector passes through and with a radially outward end portion on one Stop surface of the reflector back lies and between a retaining ring and the rear of the reflector is clamped.
  • Such a headlight for vehicles is known from DE 195 14 085 A1.
  • the headlight has a pot-shaped housing made of plastic on whose front through a translucent lens is closed.
  • a bowl-shaped reflector used, which consists of plastic and adjustable in the housing is stored.
  • In the apex area of the bowl-shaped reflector is one Opening for receiving a light element, which is an incandescent lamp, brought in.
  • the light element is through a housing opening in the rear wall of the pot-shaped housing accessible.
  • the case opening is through a Housing cap releasably closed with the housing.
  • the Light element is in the opening of the reflector by one from the back of the Mounted reflector from the reflector.
  • the aperture is cylindrical and has support arms connected to the reflector. Guide the support arms through the opening of the reflector and lie radially outwards directed end sections on a stop surface of the reflector back. The end sections of the support arms of the panel are between the stop surface of the reflector and the retaining ring clamped.
  • the retaining ring extends into the opening of the reflector and holds the support legs on the Inside of the opening of the reflector.
  • the panel made of sheet metal is from the back of the reflector through the opening of the reflector passed through until the free end portions of their support arms to the Attach the stop surface of the rear of the reflector. Then the Retaining ring with the reflector from the back of the reflector. Of the Retaining ring first dips into the opening of the reflector until it touches the free one End sections of the support arms strikes. The next step is the Fix the retaining ring to the reflector using separate fasteners. There both the cover and the retaining ring are a separate part, the Retaining ring can be used universally with many headlights and Attach differently designed panels to the reflector.
  • the bezel has to the assembly of the retaining ring exactly to the optically effective reflection surface of the Be aligned reflector. Since the cover after its assembly with the free End sections of their support arms only loosely on the stop surface of the The back of the reflector, it is not certain that the aperture is in its position up to Fixing the retaining ring on the reflector maintains.
  • the aperture can Insert the retaining ring into the opening of the reflector from its position be moved.
  • the panel can be turned in any position the opening of the reflector can be used.
  • the light element is not exactly aligned to the reflector, since the light element is exclusively from the Retaining ring is worn.
  • a headlight for vehicles has become known from EP 0 548 555 B1, in which the panel has a single support arm, the end portion Is U-shaped, with the free leg of the U-shape on the Reflector back, the other tavern of the U-shape on the reflection surface and the web connecting the legs on the inside of the opening of the reflector is present.
  • the web of the U-shape of the support arm of the panel is on the inside held by the retaining ring engaging in the opening of the reflector.
  • the cover must be held on the edge of the opening until the retaining ring is installed be, and the reflective surface of the reflector can be created by the system The aperture on the reflective surface may be damaged.
  • the free end section of the panel is a connector part that fits into a vehicle molded connector receptacle is inserted into the front of the reflector.
  • the plug part is inserted into the plug receptacle until it is connected to one strikes the front of the connector receptacle.
  • the panel is punched out of sheet metal and has one double support arm. This makes the aperture stable with the reflector connected.
  • the support arm runs radially with its wide side surfaces optical axis of the reflector, and thus the support arm shields very little Reflecting surface of the reflector.
  • the object of the invention is that described in the preamble of claim 1 To design headlights for vehicles in such a way that with a simple and easy mounting of the retaining ring an exact location of a separate Partly formed aperture to the reflector is safe and the reflector continues on its front, which has the reflecting surface, neither Fastener still a stop surface for the support arm of the panel must have.
  • This object is achieved according to the invention in that the radially outward end portion of the support arm of the panel Plug part is that with its side facing the reflector in one to the Reflector rear molded plug receptacle and arranged in the Plug holder is held.
  • the bezel is from the back of the reflector passed through the opening of the reflector until the free one End portion of the support arm formed connector part in the connector receptacle Engages the rear of the reflector and on the stop surface of the rear of the reflector is present.
  • the aperture By between the end section and the reflector back existing connector is the aperture exactly to the reflective surface of the Reflector aligned.
  • the aperture keeps its exact position to the reflector up to the assembly of the retaining ring as well as the assembly of the Retaining rings at.
  • the mounting ring can be installed easily and easily, since the retaining ring only the plug part on the stop surface of the plug receptacle must hold.
  • the connector can go from one to the rear of the reflector molded approach be formed.
  • the reflector does not have to be on its front Fastener still a stop surface for the support arm of the panel exhibit. Due to the radially outward facing connector part of the support arm The stop surface of the rear of the reflector can be designed over a large area.
  • the plug connection between the support leg and the reflector is simple designed when the connector receptacle inserted into the rear of the reflector Has bag, which is closed to the front of the reflector and into which the connector part of the panel engages with a projection. Because of the existing connector between the panel and the reflector is also with small holding forces of the retaining ring, the panel is securely attached to the Given reflector. In this context, it is also advantageous if the projection is formed by at least one resilient element which is attached to rests resiliently on one side of the pocket of the plug receptacle. This is a the plug part can be easily inserted into the plug receptacle.
  • the bracket's arm is firmly attached to the reflector, if the support arm has a groove which is in the joining direction of its plug part is open and of the free end portion of the support arm, the Projection and the support arm is limited, and the reflector one in the groove engaging spring, the groove against the joining direction narrowed. This continues to be a simple and easy insertion of the Given connector part in the connector receptacle of the reflector, and from the The front side of the reflector is the end section having the projection the connector part is not visible.
