Definitions

  • the invention relates to a headlight for vehicles with a bowl-shaped reflector made of plastic, the opening for receiving the light bulb is surrounded by an outwardly projecting collar, with a light bulb inserted into the collar from the back of the reflector, the bulb socket surrounding flange abuts the end face of the collar, with a U-shaped wire spring seen in the direction of the optical axis towards the rear of the reflector, the legs of which bear on opposite sides of the flange of the incandescent lamp under tension and is attached to two holding devices which are formed on the other two opposite sides of the opening receiving the light bulb on the reflector and the first holding device receiving the free ends of the legs of the wire spring serves as a pivot bearing, the axis of which extends transversely to the legs, for the wire spring, while the second holding member direction has at least one undercut, which is engaged by the wire spring self-locking.
  • a headlight of this type is known from DE-AS 1 281 371.
  • the incandescent lamp inserted into the collar from the rear of the plastic reflector lies with its incandescent lamp base on the end face of the collar.
  • a holding device for the wire spring that fixes the light bulb to the reflector is molded onto the reflector.
  • the wire spring is essentially U-shaped and rests with the two legs on the two other opposite sides of the flange of the bulb base under prestress.
  • the free ends of the wire spring are bent outwards and rotatably supported in openings of one of the two holding devices.
  • the other holding device is arranged between the two legs of the wire spring.
  • the sides of the holding device facing the two legs each have a projection which forms an undercut.
  • the undercuts are caught behind by the legs of the wire spring.
  • the tool of the reflector is relatively complex to construct, since an adjustable tool part is necessary for the production of the two undercuts.
  • changing the light bulb is very cumbersome and can only be carried out by a specialist, since the two legs of the wire spring do not have a handle that makes it easier to loosen. This applies particularly to the usually very limited space on the back of the headlight.
  • the disadvantage described above has a particularly strong effect if the wire spring is to bear against the flange of the incandescent lamp with a very high prestress.
  • it is advantageous here that a secure tight fit of the incandescent lamp is ensured on the reflector and the wire spring can counteract a high pull-off force of a plug placed on the incandescent lamp base. This advantage should be retained in the invention.
  • the second holding device having the undercut is molded onto the reflector at a distance from the collar. This allows the legs of the wire spring to be produced in any desired length.
  • the light bulb (5) is fixed to the reflector (1) by a wire spring (13) which bears against the flange (6) of the light bulb (5) under pre-tension.
  • the wire spring (13) is bent in a U-shape as seen in the direction of the optical axis on the back of the reflector (1).
  • the protective collar (8) is arranged between the legs (14) of the wire spring.
  • the wire spring (13) lies with the central, U-shaped area (15) under prestress on the flange (6) of the incandescent lamp (5).
  • the wire spring (13) is fixed to the reflector (1) on the holding devices (16 and 17) formed on opposite sides of the collar (4).
  • the wire spring (13) is pivotably mounted on the first holding device (16) with the free ends (31) of the legs (14) bent outwards.
  • the free end section (18) of the legs (14) of the wire spring (13) is bent towards the rear of the reflector (1).
  • the outwardly bent free ends (31) of the wire spring (13) are rotatably inserted in bores of two projections (32) of the first holding device (16) molded onto the back and outside of the collar (4).
  • the pivot axis (19) of the wire spring (13) extends transversely to its legs (14).
  • the sections (21) of the legs (14) adjoining the web (20) of the wire spring (13) connecting the legs are bent towards the rear of the reflector.
  • the free end section of the lever projects over the edge (28) serving as the pivot point by about 2/3 of its entire length.
  • the sections (23) of the web (20) of the wire spring (13) pivot out of the undercuts (24).
  • the web (20) connecting the legs (14) can then be pivoted over the protective collar (8) surrounding the contact tabs (7).
  • the lever (22) serves as a handle.
  • the sections (23) of the web (20) lying next to the lever (22) slide along run-up slopes (29) of the columns of the second holding device (17) until they engage behind the undercut (24) of the columns (25) in a self-locking manner.
  • the second holding device (17) has two walls (30) formed parallel to one another and to the rear of the reflector for guiding and holding, between which the wire spring (13) with its sections (21) of the legs adjoining the web (20) (14) is arranged.
  • the wire spring (13) and their holding devices (16 and 17) are shown, that is, the pivot bearing of the wire spring can, for. B. can also be arranged below the incandescent lamp.
